UpdatePoint # will empty point and rcpoint, and set betapoint=0. # ## STABLE: # # To start a -stable beta cycle, which normally occurs before a -stable # -RC1 during the runup to a -stable point release, UpdatePoint needs # no changes here. Both betapoint and point will be incremented, and # prerelease will be set to beta. # # To move on from -stable beta to RC set prerelease=rc. # # To fall back from -stable RC to beta set prerelease=beta. # # To skip over -stable beta1 directly to -RC1, set prerelease=rc. # # To skip all -stable prereleases and move from one primary or point # release directly to the next point release, or to go from RC to # release, set rcpoint=GO. # ## # # To see what UpdatePoint will do without modifying packageinfo.sh as it # does by default, use the -t/--test option before the repo type: # # shell# scripts/UpdatePoint -t stable # # repotype must be stable or dev repotype=stable # version=Protocol.Major.Minor # odd minor numbers are for -dev, even minor numbers are for -stable # UpdatePoint will fail if repotype is inconsistent with minor. proto=4 major=2 minor=6 version=${proto}.${major}.${minor} # Special.

See http://support.ntp.org/security for more information. NTP mode 7 (MODE_PRIVATE) is used by the ntpdc query and control utility. In contrast, ntpq uses NTP mode 6 (MODE_CONTROL), while routine NTP time transfers use modes 1 through 5. Upon receipt of an incorrect mode 7 request or a mode 7 error response from an address which is not listed in a "restrict ... noquery" or "restrict ... ignore" statement, ntpd will reply with a mode 7 error response (and log a message). In this case: * If an attacker spoofs the source address of ntpd host A in a mode 7 response packet sent to ntpd host B, both A and B will continuously send each other error responses, for as long as those packets get through. * If an attacker spoofs an address of ntpd host A in a mode 7 response packet sent to ntpd host A, A will respond to itself endlessly, consuming CPU and logging excessively. Credit for finding this vulnerability goes to Robin Park and Dmitri Vinokurov of Alcatel-Lucent. THIS IS A STRONGLY RECOMMENDED UPGRADE. --- ntpd now syncs to refclocks right away. Backward-Incompatible changes: ntpd no longer accepts '-v name' or '-V name' to define internal variables. Use '--var name' or '--dvar name' instead. (Bug 817) --- NTP 4.2.4p7 (Harlan Stenn , 2009/05/04) Focus: Security and Bug Fixes Severity: HIGH This release fixes the following high-severity vulnerability: * [Sec 1151] Remote exploit if autokey is enabled. CVE-2009-1252 See http://support.ntp.org/security for more information. If autokey is enabled (if ntp.conf contains a "crypto pw whatever" line) then a carefully crafted packet sent to the machine will cause a buffer overflow and possible execution of injected code, running with the privileges of the ntpd process (often root). Credit for finding this vulnerability goes to Chris Ries of CMU. This release fixes the following low-severity vulnerabilities: * [Sec 1144] limited (two byte) buffer overflow in ntpq. CVE-2009-0159 Credit for finding this vulnerability goes to Geoff Keating of Apple. * [Sec 1149] use SO_EXCLUSIVEADDRUSE on Windows Credit for finding this issue goes to Dave Hart. This release fixes a number of bugs and adds some improvements: * Improved logging * Fix many compiler warnings * Many fixes and improvements for Windows * Adds support for AIX 6.1 * Resolves some issues under MacOS X and Solaris THIS IS A STRONGLY RECOMMENDED UPGRADE. --- NTP 4.2.4p6 (Harlan Stenn , 2009/01/07) Focus: Security Fix Severity: Low This release fixes oCERT.org's CVE-2009-0021, a vulnerability affecting the OpenSSL library relating to the incorrect checking of the return value of EVP_VerifyFinal function. Credit for finding this issue goes to the Google Security Team for finding the original issue with OpenSSL, and to ocert.org for finding the problem in NTP and telling us about it. This is a recommended upgrade. --- NTP 4.2.4p5 (Harlan Stenn , 2008/08/17) Focus: Minor Bugfixes This release fixes a number of Windows-specific ntpd bugs and platform-independent ntpdate bugs. A logging bugfix has been applied to the ONCORE driver. The "dynamic" keyword and is now obsolete and deferred binding to local interfaces is the new default. The minimum time restriction for the interface update interval has been dropped. A number of minor build system and documentation fixes are included. This is a recommended upgrade for Windows. --- NTP 4.2.4p4 (Harlan Stenn , 2007/09/10) Focus: Minor Bugfixes This release updates certain copyright information, fixes several display bugs in ntpdc, avoids SIGIO interrupting malloc(), cleans up file descriptor shutdown in the parse refclock driver, removes some lint from the code, stops accessing certain buffers immediately after they were freed, fixes a problem with non-command-line specification of -6, and allows the loopback interface to share addresses with other interfaces. --- NTP 4.2.4p3 (Harlan Stenn , 2007/06/29) Focus: Minor Bugfixes This release fixes a bug in Windows that made it difficult to terminate ntpd under windows. This is a recommended upgrade for Windows. --- NTP 4.2.4p2 (Harlan Stenn , 2007/06/19) Focus: Minor Bugfixes This release fixes a multicast mode authentication problem, an error in NTP packet handling on Windows that could lead to ntpd crashing, and several other minor bugs. Handling of multicast interfaces and logging configuration were improved. The required versions of autogen and libopts were incremented. This is a recommended upgrade for Windows and multicast users. --- NTP 4.2.4 (Harlan Stenn , 2006/12/31) Focus: enhancements and bug fixes. Dynamic interface rescanning was added to simplify the use of ntpd in conjunction with DHCP. GNU AutoGen is used for its command-line options processing. Separate PPS devices are supported for PARSE refclocks, MD5 signatures are now provided for the release files. Drivers have been added for some new ref-clocks and have been removed for some older ref-clocks. This release also includes other improvements, documentation and bug fixes. K&R C is no longer supported as of NTP-4.2.4. We are now aiming for ANSI C support. --- NTP 4.2.0 (Harlan Stenn , 2003/10/15) Focus: enhancements and bug fixes. ntp-4.2.6p5/flock-build0000755000175000017500000000570211336477343013751 0ustar peterpeter#! /bin/sh IAM=`hostname || uname -n` MYNAME=`IFS=. ; set $IAM ; echo $1` case "$1" in '--one'|'-1') shift FB_FIRSTONLY=1 LIST=$MYNAME ;; *) FB_FIRSTONLY=0 esac BUILD_ARGS="$@" PARSE="--enable-parse-clocks" #PARSE= STD="--enable-simulator" case "$SIMUL::$FB_FIRSTONLY" in ::*) PARALLEL_BUILDS=1 ;; *::0) PARALLEL_BUILDS=$SIMUL ;; *) PARALLEL_BUILDS=1 esac case "$PARALLEL_BUILDS" in 1) ;; *) echo Launching $PARALLEL_BUILDS parallel builds on each machine esac # Backroom: # barnstable freebsd-6.1 # beauregard freebsd-6.0 # X churchy alpha-dec-osf5.1 # deacon sparc-sun-solaris2.10 # grundoon freebsd-6.2 # howland freebsd-6.1 # o macabre freebsd-6.1-STABLE # o mort freebsd-6.1 # whimsy sparc-sun-solaris2.10 # Campus: # * baldwin sparc-sun-solaris2.10 # * bridgeport sparc-sun-solaris2.10 # * malarky sparc-sun-solaris2.10 # * pogo sparc-sun-solaris2.10 # * rackety freebsd-6.1 # HMS: we need $PWD because solaris produces /deacon/backroom when # we are in /backroom and in general there is no /deacon/backroom. c_d=${PWD:-`pwd`} SIG=`perl -e 'print rand'` case "$LIST" in '') LIST="malarky rackety" ;; esac for i in $LIST do SKIPTHIS=0 [ -f .buildkey-$i ] && SKIPTHIS=1 case "$SKIPTHIS" in 1) echo flock-build running on $i? check LIST, skipping ;; 0) echo $i echo $SIG > .buildkey-$i case "1" in 0) ssh $i "cd $c_d ; ./build $SIG $PARSE $STD $BUILD_ARGS" & ssh $i "cd $c_d ; ./build $SIG $PARSE $STD --without-crypto $BUILD_ARGS" & ssh $i "cd $c_d ; ./build $SIG $STD --disable-all-clocks $BUILD_ARGS" & ;; 1) cat > .flockbuild-$i-$SIG <<-ENDQUOT #!/bin/sh # script uses job control and expects to be invoked # in a ssh session started with the -tt option, # which forces a pseudo-tty to be used. cd $c_d COUNT=0 ./build $SIG $PARSE $STD $BUILD_ARGS & COUNT=\`expr \$COUNT + 1\` echo \`date -u '+%H:%M:%S'\` $i started build \$COUNT of 4 [ 0 -lt \`expr \$COUNT % $PARALLEL_BUILDS\` ] || wait case $FB_FIRSTONLY in '0') ./build $SIG $PARSE $STD --disable-debugging $BUILD_ARGS & COUNT=\`expr \$COUNT + 1\` echo \`date -u '+%H:%M:%S'\` $i started build \$COUNT of 4 [ 0 -lt \`expr \$COUNT % $PARALLEL_BUILDS\` ] || wait ./build $SIG $PARSE $STD --without-crypto $BUILD_ARGS & COUNT=\`expr \$COUNT + 1\` echo \`date -u '+%H:%M:%S'\` $i started build \$COUNT of 4 [ 0 -lt \`expr \$COUNT % $PARALLEL_BUILDS\` ] || wait ./build $SIG $STD --disable-all-clocks $BUILD_ARGS & COUNT=\`expr \$COUNT + 1\` echo \`date -u '+%H:%M:%S'\` $i started build \$COUNT of 4 wait esac echo \`date -u '+%H:%M:%S'\` $i flock-build $c_d done. rm .buildkey-$i ENDQUOT chmod +x .flockbuild-$i-$SIG ssh -tt $i "$c_d/.flockbuild-$i-$SIG ; \ rm $c_d/.flockbuild-$i-$SIG" 2>/dev/null & esac esac done echo `date -u '+%H:%M:%S'` flock-build launched ntp-4.2.6p5/libparse/0000755000175000017500000000000011710605402013406 5ustar peterpeterntp-4.2.6p5/libparse/data_mbg.c0000644000175000017500000002730211307651604015323 0ustar peterpeter/* * /src/NTP/REPOSITORY/ntp4-dev/libparse/data_mbg.c,v 4.8 2006/06/22 18:40:01 kardel RELEASE_20060622_A * * data_mbg.c,v 4.8 2006/06/22 18:40:01 kardel RELEASE_20060622_A * * $Created: Sun Jul 20 12:08:14 1997 $ * * Copyright (c) 1997-2005 by Frank Kardel ntp.org> * * Redistribution and use in source and binary forms, with or without * modification, are permitted provided that the following conditions * are met: * 1.

To address # this issue, we use a deps-ver file which is updated with each change # that breaks old .deps files. A copy of deps-ver is made into # $(DEPDIR) if not already present.

For this reason, we use the # intermediate target .deps-ver, which invokes make recursively if # DEPDIR exists. # # If you modify depsver.mf, please make the changes to the master # copy, the one in sntp is copied by the bootstrap script from it. # # This comment block follows rather than leads the related code so that # it stays with it in the generated Makefile.in and Makefile. # # Tell versions [3.59,3.63) of GNU make to not export all variables. # Otherwise a system limit (for SysV at least) may be exceeded. .NOEXPORT: ntp-4.2.6p5/libparse/clk_trimtsip.c0000644000175000017500000003264211307651603016273 0ustar peterpeter/* * /src/NTP/REPOSITORY/ntp4-dev/libparse/clk_trimtsip.c,v 4.19 2009/11/01 10:47:49 kardel RELEASE_20091101_A * * clk_trimtsip.c,v 4.19 2009/11/01 10:47:49 kardel RELEASE_20091101_A * * Trimble TSIP support * Thanks to Sven Dietrich for providing test hardware * * Copyright (c) 1995-2009 by Frank Kardel ntp.org> * Copyright (c) 1989-1994 by Frank Kardel, Friedrich-Alexander Universität Erlangen-Nürnberg, Germany * * Redistribution and use in source and binary forms, with or without * modification, are permitted provided that the following conditions * are met: * 1.

For reasonably sane clocks this refclock drivers allows a refclock implementation by just providing a conversion routine and the appropriate NTP parameters. Refclock support can run as low a 3k code with the parse refclock driver. The modules in here are designed to live in two worlds. In userlevel as part of the xntp daemon and in kernel land as part of a STREAMS module or, if someone gets to it, as part of a line discipline. Currently only SunOS4.x/SunOS5.x STREAMS are supported (volunteers for other vendors like HP?). This structure means, that refclock_parse can work with or without kernel support. Kernelsupport increases accuracy tremendingly. The current restriction of the parse driver is that it only supports SYSV type ttys and that kernel support is only available for Suns right now. Three kernel modules are part of this directory. These work only on SunOS (SunOS4 and SunOS5). SunOS4 (aka Solaris 1.x): parsestreams.loadable_module.o - standard parse module for SunOS 4 Both modules can be loaded via modload . SunOS5 (aka Solaris 2.x): parse - auto loadable streams module To install just drop "parse" into /kernel/strmod and start the daemon (SunOS5 will do the rest). The structure of the parse reference clock driver is as follows: ntpd - contains NTP implementation and calls a reference clock 127.127.8.x which is implemented by refclock_parse.c - which contains several refclock decriptions. These are selected by the x part of the refclock address. The lower two bits specify the device to use. Thus the value (x % 4) determines the device to open (/dev/refclock-0 - /dev/refclock-3). The kind of clock is selected by the mode parameter. This parameter selects the clock type which deterimines how I/O is done, the tty parameters and the NTP parameters. refclock_parse operates on an abstract reference clock that delivers time stamps and stati. Offsets and sychron- isation information is derived from this data and passed on to refclock_receive of xntp which uses that data for syncronisation. The abstract reference clock is generated by the parse* routines. They parse the incoming data stream from the clock and convert it to the appropriate time stamps. The data is also mapped int the abstract clock states POWERUP - clock has no valid phase and time code information NOSYNC - Time code is not confirmed, phase is probably ok. SYNC - Time code and phase are correct. A clock is trusted for a certain time (type parameter) when it leaves the SYNC state. This is derived from the observation that quite a few clocks can still generate good time code information when losing contact to their synchronisation source. When the clock does not reagain synchronisation in that trust period it will be deemed unsynchronised until it regains synchronisation. The same will happen if xntp sees the clock unsynchronised at startup. The upper bit of x specifies that all samples delivered from the clock should be used to discipline the NTP loopfilter. For clock with accurate once a second time information this means big improvements for time keeping. A prerequisite for passing on the time stamps to the loopfilter is, that the clock is in synchronised state. parse.c These are the general routines to parse the incoming data stream. Usually these routines should not require modification. clk_*.c These files hole the conversion code for the time stamps and the description how the time code can be parsed and where the time stamps are to be taken. If you want to add a new clock type this is the file you need to write in addition to mention it in parse_conf.c and setting up the NTP and TTY parameters in refclock_parse.c. Further information can be found in parse/README.parse and the various source files.

The result is a really hot audio driver for the NIST WWV/WWVH time/frequency station plus a makeover for the CHU audio driver. Currently, they and their IRIG audio driver buddy use the SunOS/Solaris audio interface, which is clean and simple. I hook the line in jack to a shortwave radio and these drivers (driver 7 for CHU and driver 36 for WWV) and the drivers do the rest. The WWV/H driver is really hot - I am currently watching the ionosphere move from the doppler that shows up on the tick modulation tracked by the program. During midday when the F2 layer settles down, the program closes in on a few tens of microseconds of spare jitter and wander. This watch on whichever 15/20 MHz signal sounds the best. At night on 5/10 MHz and even 2.5 HMz where the multipath, interference and noise are much worse, the driver bangs around somewhat more. The CHU driver makeover discovered a few broken bones after all these years, but its majority decoder is back in business. For various reasons to icky to reveal here, its 103-modem demodulator is not quite as good as the chip, but it comes close and hey, 2025/2125 FSK is just not a good idea for HF radio. This driver is not nearly as sophisitcated as the WWV/H driver, but here a few hundred miles south of Ottawa, it does a passably good job. I tell you this in the hopes of getting somebody interested in porting the audio interface to other machines, in particular Linux, FreeBSD and anything else with a sound card. When the ionosphere stays cool, the WWV/H driver is as good as anything else around here and with much less jitter than a serial port. The only downside is all the audio drivers chew up a modest fraction of cycles for the DSP routines - a few percent on the newer silicon, up to half the cycles on an old Sparc IPC. Whattheheck, these old machines aren't doing anything else around here except serving time, and even when sucking cycles for DSP they still mind the PPS microseconds. The audio driver documentation had a makeover, too.

Description:
  $program prints per host given in  the NTP stratum level, the
  clock offset in seconds, the daemon version, the operating system and
  the processor. Optionally recursing through all peers.

Options:
--help
    Print this short help text and exit.
--version
    Print version ($version) and exit.

    Specify hosts file. File format is one hostname or ip number per line.
    Lines beginning with # are considered as comment.
--host 
    Speficy a single host, bypassing the need for a hosts file.
--peers
    Recursively list all peers a host synchronizes to.
    An '= ' before a peer means a loop. Recursion stops here.
--maxlevel 
    Traverse peers up to this level (4 is a reasonable number).
--strip 
    Strip  from hostnames.

Examples:
    $program myhosts.txt --strip .foo.com
    $program --host some.host --peers --maxlevel 4

    exit 1;

Following are examples of the serial timecode formats used by various
timecode receivers as given in the instruction manuals. These examples
are intended only for illustration and not as the basis of system
design. The following symbols are used to identify the timecode
character that begins a subfield. The values given after this symbol
represent the character offset from the beginning of the timecode string
as edited to remove control characters.

C         on-time character (start bit)
Y         year of century
T         time of day
D         day of year or month/day
A         alarm indicator (format specific)
Q         quality indicator (format specific)
      ASCII line feed (hex 0a)
      ASCII carriage return (hex 0d)
      ASCII space (hex 20)

In order to promote uniform behavior in the various implementations, it
is useful to have a common interpretation of alarm conditions and signal
quality. When the alarm indicator it on, the receiver is not operating
correctly or has never synchronized to the broadcast signal. When the
alarm indicator is off and the quality indicator is on, the receiver has
synchronized to the broadcast signal, then lost the signal and is
coasting on its internal oscillator.

In the following uppercase letters, punctuation marks and spaces 
stand for themselves; lowercase letters stand for fields as described.
Special characters other than ,  and  are preceded by ^.

Spectracom 8170 and Netclock/2 WWV Synchonized Clock (format 0)

"i  ddd hh:mm:ss  TZ=zz"
 C       A  D   T

     poll: ?; offsets: Y = none, D = 3, T = 7, A = 0, Q = none
     i = synchronization flag ( = in synch, ? = out synch)
     ddd = day of year
     hh:mm:ss = hours, minutes, seconds
     zz = timezone offset (hours from UTC)

     Note: alarm condition is indicated by other than  at A, which
     occurs during initial synchronization and when received signal has
     been lost for about ten hours

     example: "   216 15:36:43  TZ=0"
               A  D   T

Netclock/2 WWV Synchonized Clock (format 2)

"iqyy ddd hh:mm:ss.fff ld"
 C       AQY  D   T

     poll: ?; offsets: Y = 2, D = 5, T = 9, A = 0, Q = 1
     i = synchronization flag ( = in synch, ? = out synch)
     q = quality indicator ( < 1ms, A < 10 ms, B < 100 ms, C < 500
     ms, D > 500 ms)
     yy = year (as broadcast)
     ddd = day of year
     hh:mm:ss.fff = hours, minutes, seconds, milliseconds of day
     l = leap-second warning (L indicates leap at end of month)
     d = standard/daylight time indicator ( standard, D daylight)

     Note: alarm condition is indicated by other than  at A, which
     occurs during initial synchronization and when received signal has
     been lost for about ten hours; unlock condition is indicated by
     other than  at Q, with time since last lock indicated by the
     letter code A < 13 min, B < 1.5 hr, C < 7 hr, D > 7 hr.

     example: "  92 216 15:36:43.640  D"

     poll: none; offsets: Y = none, D = 0, T = 4, A = 12, Q = 12
     hh:mm:ss = hours, minutes, seconds
     q = quality/alarm indicator ( = locked, ? = alarm)

     Note: alarm condition is indicated by ? at A, which occurs during
     initial synchronization and when received signal is lost for an
     extended period; unlock condition is indicated by other than 
     at Q

     example: "216:15:36:43 "
               D   T       Q

Heath GC-1000 Most Accurate Clock (WWV/H)

"hh:mm:ss.f     dd/mm/yy"
 C   T        A     D

     poll: none; offsets: Y = none, D = 15, T = 0, A = 9, Q = none
     hh:mm:ss = hours, minutes, seconds
     f = deciseconds (? when out of spec)
     dd/mm = day, month
     yy = year of century (from DIPswitches)

     Note: 0?:??:??.? is displayed before synch is first established and
     hh:mm:ss.? once synch is established and then lost again for about
     a day.

     example: "15:36:43.6     04/08/91"

     f = frequency enable (O = all frequencies enabled)
     r = baud rate (3 = 1200, 6 = 9600)
     d = features indicator (@ = month/day display enabled)
     z = time zone (0 = UTC)
     y = year (5 = 1991)
     cc = WWV propagation delay (52 = 22 ms)
     hh = WWVH propagation delay (81 = 33 ms)
     SS = status (80 or 82 = operating correctly)
     F = current receive frequency (1-5 = 2.5, 5, 10, 15, 20 MHz)
     T = transmitter (C = WWV, H = WWVH)
     tttt = time since last update (minutes)
     uu = flush character (03 = ^C)
     xx = 94 (unknown) (firmware revision X4.01.999 only)

     a = AM/PM indicator (A = AM, P = PM,  - 24-hour format)
     hh:mm:ss.fff = hours, minutes, seconds, milliseconds of day
     s = daylight-saving indicator ( standard, D daylight)

     yy = year of century (from DIPswitches)
     dd/mm/ddd = day of month, month of year, day of year

     Note: The alarm condition is indicated by other than ? at A, which
     occurs during initial synchronization and when received signal is
     lost for an extended period. A receiver unlock condition is
     indicated by other than "0000" in the tttt subfield at Q.

The xntp3 daemon can produce a variety of statistics files which are
useful for maintenance, evaluation and retrospective calibration
purposes. See the xntpd.8 man page for instructions on how to configure
this feature. Since these files can become rather large and cumbersome,
they are ordinarily reduced to summary form by running the summary.sh
shell script once per day, week or month, as appropriate. There are
three file collections presently defined: peerstats, loopstats and
clockstats, each of which is described in this note.

peerstats

The following data are collected in the peerstats files. The files are
reduced to summary data using the peer.sh shell script. See the peer.awk
script for further information. A line in the file is produced upon
reception of each valid update from a configured peer.

  49236 30.756 140.173.96.1 9474 0.000603 0.37532

  49236             modified Julian day number
  30.756            time of day (s) past midnight UTC
  140.173.96.1      peer identifier (IP address or receiver identifier)
  9474              peer status word (hex) (see NTP specification)
  0.000603          offset (s)
  0.08929           delay (s)
  0.37532           dispersion (s)

loopstats

The following data are collected in the loopstats files. The files are
reduced to summary data using the loop.sh shell script. See the loop.awk
script for further information. A line in the file is produced at each
valid update of the local clock.

  49236 11.897 -0.000004 -35.9384 0

  49236             modified Julian day number
  11.897            time of day (s) past midnight UTC
  -0.000004         time offset (s)
  -35.9384          frequency offset (ppm)
  0                 phase-lock loop time constant

clockstats

The following data are collected in the clockstats files. The files are
reduced to summary data using the clock.sh shell script, which also
updates the ensemble, etf, itf and tdata data files as well. See the
clock.awk, ensemble.awk, etf.awk, itf.awk and tdta.awk scripts for
further information. A line in the file is produced at each valid update
received from a configured radio clock. Data are at present recorded for
several radios. The first part of each data line is similar for all
radios, e.g.:

  49234 60517.826 127.127.4.1   93 247 16:48:21.814

  93 247 16:48:21.814  timecode (format varies)

In the case of the Austron GPS receiver, a good deal of additional
information is extracted from the radio, as described below. The formats
shown consist of one line with all the fields shown in order. The
timecode formats specific to each radio follow. See the file
README.timecodes for detailed information on the timecode formats used
by these radios.

Spectracom 8170/Netclock-2 WWVB receiver

  49234 60517.826 127.127.4.1 ?A93 247 16:48:21.814

  The '?' and 'A' characters are present only when the receiver is
  unsynchronized; otherwise, they are replaced by space ' ' characters.

IRIG audio decoder

  49234 60517.826 127.127.6.0 247 16:48:21?

  The '?' character is present only when the receiver is unsynchronized.

Austron 2200A/2201A GPS receiver

  49234 60580.843 127.127.10.1 93:247:16:49:24.814?

  The '?' character is present only when the receiver is unsynchronized.

Depending on the installed options, the Austron 2200A/2201A recognizes a
number of special commands that report various data items. See the
refclock_as2201.c source module for a list of the commands used. These
data are collected only if the following line is included in the
configuration file ntp.conf:

  fudge 127.127.10.1 flag4 1    # enable extended statistics collection

The format of each data line returned is summarized in the following
list.

This directory contains a number of scripts for use with the filegen
facility. Those files ending in .awk are for the Unix awk utility, while
those ending in .sh are for the csh utility. Normally, the summary.sh
script is called from a cron job once per day. This script processes the
daily loopstats, peerstats and clockstats files produced by the daemon,
updates the loop_summary, peer_summary and clock_summary archive files,
and deletes the daily files.

In the case of the Austron 2201A GPS receiver, the clockstats file
contains a wealth of additional monitoring data. These data are summarized
and writted to the clock_summary file, then a series of special files are
constructed for later processing by the S utility.

The summary.sh script invokes a number of awk scripts to actually produce
the data. This may result in multiple scans of the same input file.
The input file is deleted after processing. In fact, the shell scripts will
process all input files found of the correct type in chronological order,
deleting each one as it is scanned, except the current day file.

The summary.sh script can produce input files for the S utility, if it
is found on the search path. This utility makes PostScript graphs of the
loopstats data for each day, as well as various statistics produced by
the Austorn 220aA GPS receiver. The S utility is automatically run
as a background job. Its control files have the .S extension.

The psummary.awk script can be used to scan the peer_summary file and
construct an historical reprise of the daily summaries. 

The file formats are documented in the README.stats file and in the
scripts themselves. Further detail on the radio clock ASCII timecode
formats and related data are in the README.timecode file.

;#
;# Usage:
;#	$time = timelocal($sec,$min,$hours,$mday,$mon,$year,$junk,$junk,$isdst);
;#	$time = timegm($sec,$min,$hours,$mday,$mon,$year);

;# These routines are quite efficient and yet are always guaranteed to agree
;# with localtime() and gmtime().  We manage this by caching the start times
;# of any months we've seen before.  If we know the start time of the month,
;# we can always calculate any time within the month.  The start times
;# themselves are guessed by successive approximation starting at the
;# current time, since most dates seen in practice are close to the
;# current date.  Unlike algorithms that do a binary search (calling gmtime
;# once for each bit of the time value, resulting in 32 calls), this algorithm
;# calls it at most 6 times, and usually only once or twice.  If you hit
;# the month cache, of course, it doesn't call it at all.

;# timelocal is implemented using the same cache.  We just assume that we're
;# translating a GMT time, and then fudge it when we're done for the timezone
;# and daylight savings arguments.  The timezone is determined by examining
;# the result of localtime(0) when the package is initialized.  The daylight
;# savings offset is currently assumed to be one hour.

WARNING: The scripts and routines contained in this directory are beta
	 release!  Do not depend on their correct operation. They are,
	 however, in regular use at University of Erlangen-Nuernberg.
	 No severe problems are known for this code.

!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
PLEASE THINK TWICE BEFORE STARTING MONITORING REMOTE XNTP DEAMONS !!!!
MONITORING MAY INCREASE THE LOAD OF THE DEAMON MONITORED AND MAY
INCREASE THE NETWORK LOAD SIGNIFICANTLY
!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!


Files are:

README:
	This file

ntptrap:
	perl script to log ntp mode 6 trap messages.

	It sends a set_trap request to each server given and dumps the
	trap messages received. It handles refresh of set_trap.
	Currently it handles only NTP V2, however the NTP V3 servers
	also accept v2 requests. It will not interpret v3 system and
	peer stati correctly.

	usage:
	  ntptrap [-n] [-p ] [-l ] servers...
	
	-n:		do not send set_trap requests

	port:		port to listen for responses
			useful if you have a configured trap

	debug-output:	file to write trace output to (for debugging)

	This script convinced me that ntp trap messages are only of
	little use.

ntploopstat:
	perl script to gather loop info statistics from xntpd via mode 7
	LOOP_INFO requests.

	This script collects data to allow monitoring of remote xntp servers
	where it is not possible to directly access the loopstats file
	produced by xntpd itself. Of course, it can be used to sample
	a local server if it is not configured to produce a loopstats file.

	Please note, this program poses a high load on the server as
	a communication takes place every delay seconds ! USE WITH CARE !

	usage:
	  ntploopstat [-d] [-t] [-l ] [-v] [ntpserver]
	
	delay:		number of seconds to wait between samples
			default: 60 seconds
	timeout:	number of seconds to wait for reply
			default 12 seconds
	logfile:	file to log samples to
			default: loopstats::
			(note the trailing colon)
			This name actually is a prefix.
			The file name is dynamically derived by appending
			the name of the month the sample belongs to.
			Thus all samples of a month end up in the same file.

	the format of the files generated is identical to the format used by
	xntpd with the loopstats file:
		MJD  offset frequency compliance
	
	if a timeout occurs the next sample is tried after delay/2 seconds

	The script will terminate after MAX_FAIL (currently 60)
	consecutive errors.

	Errors are counted for:
		- error on send call
		- error on select call
		- error on recv call
		- short packet received
		- bad packet 
		- error on open for logfile

ntploopwatch:
	perl script to display loop filter statistics collected by ntploopstat
	or dumped directly by xntpd.

	Gnuplot is used to produce a graphical representation of the sample
	values, that have been preprocessed and analysed by this script.

	It can either be called to produce a printout of specific data set or
	used to continously monitor the values. Monitoring is achieved by 
	periodically reprocessing the logfiles, which are updated regularly
	either by a running ntploopstat process or by the running xntpd.

	usage:
	  to watch statistics permanently:
	     ntploopwatch [-v[]] [-c ] [-d ]

	  to get a single print out specify also
			  -P [-s]
				      [-S ] [-E ]
				      [-O ] [-o ]
	
	level:		level of verbosity for debugging
	config-file:	file to read configurable settings from
			On each iteration it is checked and reread
			if it has been changed
			default: loopwatch.config
	working-dir:	specify working directory for process, affects
			interpretation of relative file names
	
	All other flags are only useful with printing plots, as otherwise
	command line values would be replaced by settings from the config file.

	printer:	specify printer to print plot
			BSD print systems semantics apply; if printer
			is omitted the name "ps" is used; plots are
			prepared using PostScript, thus the printer
			should best accept postscript input

	For the following see also the comments in loopwatch.config.SAMPLE

	samples:	use last # samples from input data
	start-time:	ignore input samples before this date
	end-time:	ignore input samples after this date
			if both start-time and end-time are specified
			a given samples value is ignored
	MaxOffs:
	MinOffs:	restrict value range 

loopwatch.config.SAMPLE:
	sample config file for ntploopwatch
	each configurable option is explained there

lr.pl:
	linear regression package used by ntploopwatch to compute
	linear approximations for frequency and offset values
	within display range

timelocal.pl:

	used during conversion of ISO_DATE_TIME values specified in
	loopwatch config files to unix epoch values (seconds since
	1970-01-01_00:00_00 UTC)

	A version of this file is distributed with perl-4.x, however,
	it has a bug related to dates crossing 1970, causing endless loops..
	The version contained here has been fixed.

ntp.pl:
	perl support for ntp v2 mode 6 message handling
	WARNING: This code is beta level - it triggers a memory leak;
		 as for now it is not quite clear, wether this is caused by a
		 bug in perl or by bad usage of perl within this script.

This directory contains shell and perl script files for the configuration,
monitoring and support of NTP installations. See the README and RELNOTES
files in the parent directory for directions on how to use these files.

calc_tickadj	Calculates "optimal" value for tick given ntp.drift file

freq_adj	Calculates and optionally sets the clock frequency
		based on ntp.drift .  For FreeBSD systems.

mkver.in	script to create new version numbers for all sources

monitoring      directory containing perl scripts useful for monitoring
                operations

rc1		start/stop scripts for NTP

rc2		start/stop script for NTP

ntp-close	find public stratum 2 servers that don't respond

ntp-groper	script useful for reaching out and rattling the cages of
		NTP peers to see if animals are inside the bars

ntp-restart	script useful for killing and restarting the NTP daemon

ntp-wait	Blocks until ntpd is in state 4 (synchronized).
		Hopefully useful at boot time, to delay the boot sequence
		until after "ntpd -g" has set the time.

ntpsweep	prints per host given in  the NTP stratum level, the
		clock offset in seconds, the daemon version, the operating
		system and the processor.

ntpver		What version of the NTP daemon is running?

stats		directory containing awk and shell scripts useful for
		maintaining statistics summaries of clockstats, loopstats
		and peerstats files

support         directory containing shell and perl scripts useful for
                configuration and monitoring of NTP subnets

 * NTP uses two fixed point formats.  The first (l_fp) is the "long"
 * format and is 64 bits long with the decimal between bits 31 and 32.
 * This is used for time stamps in the NTP packet header (in network
 * byte order) and for internal computations of offsets (in local host
 * byte order). We use the same structure for both signed and unsigned
 * values, which is a big hack but saves rewriting all the operators
 * twice. Just to confuse this, we also sometimes just carry the
 * fractional part in calculations, in both signed and unsigned forms.
 * Anyway, an l_fp looks like:
 *
 *    0			  1		      2			  3
 *    0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1

  NTP_SYSCALLS_STD	- use the "normal" ones

HOW TO GET IP INTERFACE INFORMATION

  Some UNIX V.4 machines implement a sockets library on top of
  streams. For these systems, you must use send the SIOCGIFCONF down
  the stream in an I_STR ioctl. This ususally also implies
  USE_STREAMS_DEVICE FOR IF_CONFIG. Dell UNIX is a notable exception.

WHAT DOES IOCTL(SIOCGIFCONF) RETURN IN THE BUFFER

  UNIX V.4 machines implement a sockets library on top of streams.
  When requesting the IP interface configuration with an ioctl(2) calll,
  an array of ifreq structures are placed in the provided buffer.  Some
  implementations also place the length of the buffer information in
  the first integer position of the buffer.

  SIZE_RETURNED_IN_BUFFER - size integer is in the buffer

WILL IOCTL(SIOCGIFCONF) WORK ON A SOCKET

  Some UNIX V.4 machines do not appear to support ioctl() requests for the
  IP interface configuration on a socket.  They appear to require the use
  of the streams device instead.

  USE_STREAMS_DEVICE_FOR_IF_CONFIG - use the /dev/ip device for configuration

MISC

  DOSYNCTODR		- Resync TODR clock  every hour.
  RETSIGTYPE		- Define signal function type.
  NO_SIGNED_CHAR_DECL - No "signed char" see include/ntp.h
  LOCK_PROCESS		- Have plock.

 * membership in several lists at once using multiple next link fields.
 *
 * When possible, placing the link field first in the entry structure
 * allows slightly smaller code to be generated on some platforms.
 *
 * LINK_SLIST(listhead, pentry, nextlink)
 *	add entry at head
 *
 * LINK_TAIL_SLIST(listhead, pentry, nextlink, entrytype)
 *	add entry at tail.  This is O(n), if this is a common
 *	operation the FIFO template may be more appropriate.
 *
 * LINK_SORT_SLIST(listhead, pentry, beforecur, nextlink, entrytype)
 *	add entry in sorted order.  beforecur is an expression comparing
 *	pentry with the current list entry.  The current entry can be
 *	referenced within beforecur as L_S_S_CUR(), which is short for
 *	LINK_SORT_SLIST_CUR().  beforecur is nonzero if pentry sorts
 *	before L_S_S_CUR().
 *
 * UNLINK_HEAD_SLIST(punlinked, listhead, nextlink)
 *	unlink first entry and point punlinked to it, or set punlinked
 *	to NULL if the list is empty.
 *
 * UNLINK_SLIST(punlinked, listhead, ptounlink, nextlink, entrytype)
 *	unlink entry pointed to by ptounlink.  punlinked is set to NULL
 *	if the entry is not found on the list, otherwise it is set to
 *	ptounlink.
 *
 * UNLINK_EXPR_SLIST(punlinked, listhead, expr, nextlink, entrytype)
 *	unlink entry where expression expr is nonzero.  expr can refer
 *	to the entry being tested using UNLINK_EXPR_SLIST_CURRENT(),
 *	alias U_E_S_CUR().  See the implementation of UNLINK_SLIST()
 *	below for an example. U_E_S_CUR() is NULL iff the list is empty.
 *	punlinked is pointed to the removed entry or NULL if none
 *	satisfy expr.
 *
 * FIFO: singly-linked lists plus tail pointer
 * ===========================================
 *
 * This is the same as FreeBSD's sys/queue.h STAILQ -- a singly-linked
 * list implementation with tail-pointer maintenance, so that adding
 * at the tail for first-in, first-out access is O(1).
 *
 * DECL_FIFO_ANCHOR(entrytype)
 *	provides the type specification portion of the declaration for
 *	a variable to refer to a FIFO queue (similar to listhead).  The
 *	anchor contains the head and indirect tail pointers.  Example:
 *
 *		#include "ntp_lists.h"
 *
 *		typedef struct myentry_tag myentry;
 *		struct myentry_tag {
 *			myentry *next_link;
 *			...
 *		};
 *
 *		DECL_FIFO_ANCHOR(myentry) my_fifo;
 *
 *		void somefunc(myentry *pentry)
 *		{
 *			LINK_FIFO(my_fifo, pentry, next_link);
 *		}
 *
 *	If DECL_FIFO_ANCHOR is used with stack or heap storage, it
 *	should be initialized to NULL pointers using a = { NULL };
 *	initializer or memset.
 *
 * HEAD_FIFO(anchor)
 * TAIL_FIFO(anchor)
 *	Pointer to first/last entry, NULL if FIFO is empty.
 *
 * LINK_FIFO(anchor, pentry, nextlink)
 *	add entry at tail.
 *
 * UNLINK_FIFO(punlinked, anchor, nextlink)
 *	unlink head entry and point punlinked to it, or set punlinked
 *	to NULL if the list is empty.
 *
 * CONCAT_FIFO(q1, q2, nextlink)
 *	empty fifoq q2 moving its nodes to q1 following q1's existing
 *	nodes.
 *
 * DLIST: doubly-linked lists
 * ==========================
 *
 * Elements on DLISTs always have non-NULL forward and back links,
 * because both link chains are circular.  The beginning/end is marked
 * by the listhead, which is the same type as elements for simplicity.
 * An empty list's listhead has both links set to its own address.
 *

 *
 * where the fields are (note that the client sends requests, the server
 * responses):
 *
 * Response Bit:  This packet is a response (if clear, packet is a request).
 *
 * More Bit:	Set for all packets but the last in a response which
 *		requires more than one packet.
 *
 * Version Number: 2 for current version
 *
 * Mode:	Always 7
 *
 * Authenticated bit: If set, this packet is authenticated.
 *
 * Sequence number: For a multipacket response, contains the sequence
 *		number of this packet.  0 is the first in the sequence,
 *		127 (or less) is the last.  The More Bit must be set in
 *		all packets but the last.
 *
 * Implementation number: The number of the implementation this request code
 *		is defined by.  An implementation number of zero is used
 *		for requst codes/data formats which all implementations
 *		agree on.  Implementation number 255 is reserved (for
 *		extensions, in case we run out).
 *
 * Request code: An implementation-specific code which specifies the
 *		operation to be (which has been) performed and/or the
 *		format and semantics of the data included in the packet.
 *
 * Err:		Must be 0 for a request.  For a response, holds an error
 *		code relating to the request.  If nonzero, the operation
 *		requested wasn't performed.
 *
 *		0 - no error
 *		1 - incompatable implementation number
 *		2 - unimplemented request code
 *		3 - format error (wrong data items, data size, packet size etc.)
 *		4 - no data available (e.g. request for details on unknown peer)
 *		5-6 I don't know
 *		7 - authentication failure (i.e. permission denied)
 *
 * Number of data items: number of data items in packet.  0 to 500
 *
 * MBZ:		A reserved data field, must be zero in requests and responses.
 *
 * Size of data item: size of each data item in packet.  0 to 500
 *
 * Data:	Variable sized area containing request/response data.  For
 *		requests and responses the size in octets must be greater
 *		than or equal to the product of the number of data items
 *		and the size of a data item.  For requests the data area
 *		must be exactly 40 octets in length.  For responses the
 *		data area may be any length between 0 and 500 octets
 *		inclusive.
 *
 * Message Authentication Code: Same as NTP spec, in definition and function.
 *		May optionally be included in requests which require
 *		authentication, is never included in responses.
 *
 * The version number, mode and keyid have the same function and are
 * in the same location as a standard NTP packet.  The request packet
 * is the same size as a standard NTP packet to ease receive buffer
 * management, and to allow the same encryption procedure to be used
 * both on mode 7 and standard NTP packets.  The mac is included when
 * it is required that a request be authenticated, the keyid should be
 * zero in requests in which the mac is not included.
 *
 * The data format depends on the implementation number/request code pair
 * and whether the packet is a request or a response.  The only requirement
 * is that data items start in the octet immediately following the size
 * word and that data items be concatenated without padding between (i.e.
 * if the data area is larger than data_items*size, all padding is at
 * the end).  Padding is ignored, other than for encryption purposes.
 * Implementations using encryption might want to include a time stamp
 * or other data in the request packet padding.  The key used for requests
 * is implementation defined, but key 15 is suggested as a default.

NTP uses A.B.C - style release numbers.

At the moment:

 A is 4, for ntp V4.
 B is the major release number.
 C is the minor release number.  Even numbers are 'stable' releases and
 odd numbers are "development" releases.

Following the release number may be the letter 'p' followed by a number.
This indicates a point (or patch) release.

Release candidates have -RC in the release number.

Here are some recent versions numbers as an example:

 4.2.2		A production release (from the ntp-stable repository)
 4.2.2p2	A production release (from the ntp-stable repository)
 4.2.3p12	A development release
 4.2.3p15-rc1	A release candidate for 4.2.4

Note that after the ntp-dev repo produces a production release it will
be copied into the ntp-stable and the cycle will repeat.

Feel free to suggest improvements...

 * until (one of) the synchronization character(s) (we allow two) is seen.
 * When the magic character arrives we take a timestamp by calling
 * microtime() and insert the eight bytes of struct timeval into the
 * buffer after the magic character.  We then wake up anyone waiting
 * for the buffer and return the whole mess on the next read.
 *
 * To use this the calling program is expected to first open the
 * port, and then to set the port into raw mode with the speed
 * set appropriately with a TIOCSETP ioctl(), with the erase and kill
 * characters set to those to be considered magic (yes, I know this
 * is gross, but they were so convenient).  If only one character is
 * magic you can set then both the same, or perhaps to the alternate
 * parity versions of said character.  After getting all this set,
 * change the line discipline to CLKLDISC and you are on your way.
 *
 * The only other bit of magic we do in here is to flush the receive
 * buffers on writes if the CRMOD flag is set (hack, hack).
 */

/*
 * We run this very much like a raw mode terminal, with the exception
 * that we store up characters locally until we hit one of the
 * magic ones and then dump it into the rawq all at once.  We keep
 * the buffered data in clists since we can then often move it to
 * the rawq without copying.  For sanity we limit the number of
 * characters between specials, and the total number of characters
 * before we flush the rawq, as follows.

/*
 * The following defines establish the engineering parameters of the
 * phase-lock loop (PLL) model used in the kernel implementation. These
 * parameters have been carefully chosen by analysis for good stability
 * and wide dynamic range.
 *
 * The hz variable is defined in the kernel build environment. It
 * establishes the timer interrupt frequency, 100 Hz for the SunOS
 * kernel, 256 Hz for the Ultrix kernel and 1024 Hz for the OSF/1
 * kernel. SHIFT_HZ expresses the same value as the nearest power of two
 * in order to avoid hardware multiply operations.
 *
 * SHIFT_KG and SHIFT_KF establish the damping of the PLL and are chosen
 * for a slightly underdamped convergence characteristic. SHIFT_KH
 * establishes the damping of the FLL and is chosen by wisdom and black
 * art.
 *
 * MAXTC establishes the maximum time constant of the PLL. With the
 * SHIFT_KG and SHIFT_KF values given and a time constant range from
 * zero to MAXTC, the PLL will converge in 15 minutes to 16 hours,
 * respectively.
 */

#define MAXTC 6			/* maximum time constant (shift) */

/*
 * The following defines establish the scaling of the various variables
 * used by the PLL. They are chosen to allow the greatest precision
 * possible without overflow of a 32-bit word.
 *
 * SHIFT_SCALE defines the scaling (shift) of the time_phase variable,
 * which serves as a an extension to the low-order bits of the system
 * clock variable time.tv_usec.
 *
 * SHIFT_UPDATE defines the scaling (shift) of the time_offset variable,
 * which represents the current time offset with respect to standard
 * time.
 *
 * SHIFT_USEC defines the scaling (shift) of the time_freq and
 * time_tolerance variables, which represent the current frequency
 * offset and maximum frequency tolerance.
 *
 * FINEUSEC is 1 us in SHIFT_UPDATE units of the time_phase variable.

/*
 * The following defines establish the performance envelope of the PLL.
 * They insure it operates within predefined limits, in order to satisfy
 * correctness assertions. An excursion which exceeds these bounds is
 * clamped to the bound and operation proceeds accordingly. In practice,
 * this can occur only if something has failed or is operating out of
 * tolerance, but otherwise the PLL continues to operate in a stable
 * mode.
 *
 * MAXPHASE must be set greater than or equal to CLOCK.MAX (128 ms), as
 * defined in the NTP specification. CLOCK.MAX establishes the maximum
 * time offset allowed before the system time is reset, rather than
 * incrementally adjusted. Here, the maximum offset is clamped to
 * MAXPHASE only in order to prevent overflow errors due to defective
 * protocol implementations.
 *
 * MAXFREQ is the maximum frequency tolerance of the CPU clock
 * oscillator plus the maximum slew rate allowed by the protocol. It
 * should be set to at least the frequency tolerance of the oscillator
 * plus 100 ppm for vernier frequency adjustments. If the kernel
 * PPS discipline code is configured (PPS_SYNC), the oscillator time and
 * frequency are disciplined to an external source, presumably with
 * negligible time and frequency error relative to UTC, and MAXFREQ can
 * be reduced.
 *
 * MAXTIME is the maximum jitter tolerance of the PPS signal if the
 * kernel PPS discipline code is configured (PPS_SYNC).
 *
 * MINSEC and MAXSEC define the lower and upper bounds on the interval
 * between protocol updates.

 * lock loop used to discipline the CPU clock oscillator to the PPS
 * signal.
 *
 * PPS_AVG is the averaging factor for the frequency loop, as well as
 * the time and frequency dispersion.
 *
 * PPS_SHIFT and PPS_SHIFTMAX specify the minimum and maximum
 * calibration intervals, respectively, in seconds as a power of two.

This directory contains system header files used by the clock discipline
and STREAMS modules in the .. (./kernel) directory.

If the precision-time kernel (KERNEL_PLL define) is configured, the
installation process requires the header file /usr/include/sys/timex.h
for the particular architecture to be in place. The file timex.h included
in this distribution is for Suns; the files for other systems can be
found in the kernel distributions available from the manufacturer's
representatives.

Description

Most radio and modem clocks used for a primary (stratum-1) NTP server
utilize serial ports operating at speeds of 9600 baud or greater. The
timing jitter contributed by the serial port hardware and software
discipline can accumulate to several milliseconds on a typical Unix
workstation. In order to reduce these errors, a set of special line
disciplines can be configured in the operating system process. These
disciplines intercept special characters or signals provided by the
radio or modem clock and save a local timestamp for later processing.

The disciplines can be compiled in the kernel in older BSD-derived
systems, or installed as System V streams modules and either compiled in
the kernel or dynamically loaded when required. In either case, they
require reconfiguration of the Unix kernel and provisions in the NTP
daemon xntpd. The streams modules can be pushed and popped from the
streams stack using conventional System V streams program primitives.
Note that not all Unix kernels support line disciplines and of those
that do, not all support System V streams. The disciplines here are
known to work correctly with SunOS 4.x kernels, but have not been tested
for other kernels.

There are two line disciplines included in the distribution. Support for
each is enabled by adding flags to the DEFS_LOCAL line of the build
configuration file ./Config.local. This can be done automatically by the
autoconfiguration build procedures, or can be inserted/deleted after the
process has completed.

tty_clk (CLK)

     This discipline intercepts characters received from the serial port
     and passes unchanged all except a set of designated characters to
     the generic serial port discipline. For each of the exception
     characters, the character is inserted in the receiver buffer
     followed by a timestamp in Unix timeval format. Both select() and
     SIGIO are supported by the discipline. The -DCLK flag is used to
     compile support for this disipline in the NTP daemon. This flag is
     included if the clkdefs.h file is found in the /sys/sys directory,
     or it can be added (or deleted) manually.

tty_chu (CHU)

     This discipline is a special purpose line discipline for receiving
     a special timecode broadcast by Canadian time and frequency
     standard station CHU. The radio signal is first demodulated by the
     300-baud modem included in the gadget box, then processed by the
     discipline and finally processed by the Scratchbuilt CHU Receiver
     discipline (type 7). This discipline should be used in raw mode.
     The -DCHU flag is used to compile support for this disipline in the
     NTP daemon. This flag is included if the chudefs.h file is found in
     the /sys/sys directory, or it can be added (or deleted) manually.

There are two sets of line disciplines. The tty_clk.c and chu_clk.c are
designed for use with older BSD systems and are compiled in the kernel.
The tty_clk_STREAMS.c and chu_clk_STREAMS.c are designed for use with
System V streams, in which case they can be either compiled in the
kernel or dynamically loaded. Since these disciplines are small,
unobtrusive, and to nothing unless specifically enabled by an
application program, it probably doesn't matter which method is choosen.

Compiling with the Kernel

The following procedures are for the tty_clk line discipline; for the
chu_clk, change "tty" to "chu".
1.   Copy tty_clk.c into /sys/os and clkdefs.h into /sys/sys.

2.   For SunOS 4.x systems, edit /sys/os/tty_conf.c using some facsimile
     of the following lines:

     #include "clk.h"
     ...
     #if NCLK > 0
     int  clkopen(), clkclose(), clkwrite(), clkinput(), clkioctl();
     #endif
     ...
     #if NCLK > 0
          { clkopen, clkclose, ttread, clkwrite, clkioctl,
            clkinput, nodev, nulldev, ttstart, nullmodem, /* 10 CLK */
            ttselect },
     #else
          { nodev, nodev, nodev, nodev, nodev,
            nodev, nodev, nodev, nodev, nodev,
            nodev },
     #endif

     For Ultrix 4.x systems, edit /sys/data/tty_conf_data.c using some
     facsimile of the following lines:

     #include "clk.h"
     ...
     #if NCLK > 0
     int  clkopen(), clkclose(), clkwrite(), clkinput(), clkioctl();
     #endif
     ...
     #if NCLK > 0
          clkopen, clkclose, ttread, clkwrite, clkioctl, /* 10 CLK */
          clkinput, nodev, nulldev, ttstart, nulldev,
     #else
          nodev, nodev, nodev, nodev, nodev,
          nodev, nodev, nodev, nodev, nodev,
     #endif

     If the kernel doesn't include the ??select() entry in the structure
     (i.e., there are only ten entry points in the structure) just leave
     it out. Also note that the number you give the line discipline (10
     in most kernels) will be specific to that kernel and will depend on
     what is in there already. The entries sould be in order with no
     missing space; that is, if there are only seven disciplines already
     defined and you want to use 10 for good reason, you should define a
     dummy 9th entry like this:

     nodev, nodev, nodev, nodev, nodev, /* 9 CLK */
     nodev, nodev, nodev, nodev, nodev,

3.   Edit /sys/h/ioctl.h and include a line somewhere near where other
     line disciplines are defined like:

     #define  CLKLDISC  10        /* clock line discipline */

     The "10" should match what you used as the number in the preceding
     step.

4.   Edit /sys/conf/files and add a line which looks like:

     sys/tty_clk.c     optional clk

5.   Edit the kernel configuration file to include the following:

     pseudo-device  tty 4  # TTY clock support
6.   Run config, then make clean, then make depend, then make vmunix,
     then reboot the new kernel.

Installing as a streams module

The following procedures are for the tty_clk_STREAMS line discipline;
for the tty_chu_STREAMS, change "clk" to "chu".

1.   Copy your choice to /sys/os, removing the "_STREAMS" in the
     filename.

2.   Copy the clkdefs.h file to /usr/include/sys, then construct a soft
     link to /sys/sys.

3.   Append to /sys/conf.common/files.cmn:

     os/tty_tty.c  optional tty

4.   Edit /sys/sun/str_conf.c. You'll want to add lines in three places.
     It'll be sort of clear where when you see the file.

     #include "tty.h"
     ...
     #if NTTY > 0
     extern struct streamtab ttyinfo;
     #endif
     ...
     #if NTTY > 0
          { "tty", &ttyinfo },
     #endif

5.   Edit /sys/[arch]/conf/[k-name] (substituting the architecture and
     kernel name) to stick in:

     pseudo-device  tty 4  # TTY clock support

     You can change "4" to anything you like. It will limit the number
     of instantiations of the tty discipline you can use at the same
     time.

6.   Run config, then make clean, then make depend, then make vmunix,
     then reboot the new kernel.

Both disciplines can be dynamically loaded using streams procedures
specific to the kernel. Before using the chu_clk discipline, all other
streams modules that may already be on the stack should be popped, then
the discipline should be pushed on the stack.

How to Use the tty_clk Line Discipline

The tty_clk line discipline defines a new ioctl(), CLK_SETSTR, which
takes a pointer to a string of no more than CLK_MAXSTRSIZE characters.
Until the first CLK_SETSTR is performed, the discipline will simply pass
through characters. Once it is passed a string by CLK_SETSTR, any
character in that string will be immediately followed by a timestamp in
Unix timeval format. You can change the string whenever you want by
doing another CLK_SETSTR. The character must be an exact, 8 bit match.
The character '\000' cannot, unfortunately, be used, as it is the string
terminator. Passing an empty string to CLK_SETSTR turns off stamping.
Passing NULL will produce undefined results.

How to Use the tty_chu Line Discipline
The tty_chu line discipline translates data received from the CHU modem
and returns chucode structures, as defined in chudefs.h, and expected by
the Scratchbuilt CHU Receiver reference clock  driver. Depending on the
settings of PEDANTIC and ANAL_RETENTIVE used when compiling the kernel,
some checking of the data may or may not be necessary.

  address enumeration, allowing ntpq and ntpdc's hardcoding to 127.0.0.1 
  on Windows to end.

  I've now spent eleven months of a sabbatical year - 7 days a week, 6-10
  hours most days - working on NTP. I have carefully reviewed every major
  algorithm, examined its original design and evolution from that design.
  I've trimmed off dead code and briar patches and did zillions of tests
  contrived to expose evil vulnerabilities. The development article is in
  rather good shape and should be ready for prime time.

  1. The protostats statistics files have been very useful in exposing
  little twitches and turns when something hiccups, like a broken PPS
  signal. Most of what used to be syslog messages are now repackaged as
  protostats messages with optional syslog as well. These can also be sent
  as traps which might be handy to tiggle a beeper or celltext. These, the
  sysstats files and cryptostats files reveal the ambient health of a busy
  server, monitor traffic and error counts and spot crypto attacks.

  2. Close inspection of the clock discipline behavior at long poll
  intervals (36 h) showed it not doing as well as it should. I redesigned
  the FLL loop to improve nominal accuracy from  several tens of
  milliseconds to something less than ten milliseconds.

  3. Autokey (again). The enhanced error checking was becoming a major
  pain. I found a way to toss out gobs of ugly fat code and replace the
  function with a much simpler and more comprehensive scheme. It resists
  bait-and-switch attacks and quickly detect cases when the protocol is
  not correctly synchronized.

  4. The interface code for the kernel PPS signal was not in sync with the
  kernel code itself. Some error checks were duplicated and some
  ineffective. I found none of the PPS-capable drivers, including the atom
  driver, do anything when the prefer peer fails; the kernel PPS signal
  remains in control. The atom driver now disables the kernel PPS when the
  prefer peer comes bum. This is important when the prefer peer is not a
  reference clock but a remote NTP server.

  5. The flake restrict bit turned out to be really interesting,
  especially with symmtric modes and of those especially those using
  Autokey. Small changes in the recovery procedures when packets are lost
  now avoid almost all scenarios which previously required protocol resets.

  6. I've always been a little uncomfortable when using the clock filter
  with long poll intervals because the samples become less and less
  correlated as the sample age exceeds the Allan intercept. Various
  schemes have been used over the years to cope with this fact. The latest
  one and the one that works the best is to use a modified sort metric
  where the delay is used when the age of the sample is less than the
  intercept and the sum of delay and dispersion above that. The net result
  is that, at small poll intervals the algorithm operates as a minimum
  filter, while at larger poll intervals it morphs to FIFO. Left
  unmodified, a sample could be used when twelve days old. This along with
  the FLL modifications has made a dramatic improvement at large poll
  intervals.

- [Backward Incompatible] The 'state' variable is no longer reported or
  available via ntpq output.  The following system status bit names
  have been changed:
  - sync_alarm -> leap_alarm
  - sync_atomic -> sync_pps
  - sync_lf_clock -> sync_lf_radio
  - sync_hf_clock -> sync_hf_radio
  - sync_uhf_clock -> sync_uhf_radio
  - sync_local_proto -> sync_local
  - sync_udp/time -> sync_other
  Other names have been changed as well.  See the change history for
  libntp/statestr.c for more details.
  Other backward-incompatible changes in ntpq include:
  - assID -> associd
  - rootdispersion -> rootdisp
  - pkt_head -> pkt_neader
  See the change history for other details.

This is a distribution of the Network Time Protocol (NTP) Version 4
sources and documentation. NTP can be used by Unix, DEC VMS and
Microsoft Windows NT platforms to synchronize the computer clock to
external sources of time, such as other NTP time servers or a local
radio clock. The daemon included in this distribution can operate as a
server, a client, or a relay from a set of servers to a dependent client
population on a local net. This distribution includes the daemon itself,
plus utility programs and supporting documentation.

You are welcome to the lot, with due consideration of the copyright
information in the COPYRIGHT file. You are also invited to contribute
bugfixes and drivers for new and exotic radios, telephones and sundials.
This distribution is normally available by anonymous ftp as the
compressed tar archive ntp-.tar.gz in the pub/ntp directory on
huey.udel.edu and  is the version number. The current stable
and development version numbers can be found at .

A considerable amount of documentation, including build instructions,
configuration advice, program usage and miscellaneous information is
included in the ./html directory of this distribution. The intended
access method is using a web browser such as netscape; however, the
pages have been formatted so that viewing with an ordinary text editor
is practical. Start the browser on the ./html/index.html page, which
contains additional instructions and hotlinks to the remaining pages.
Some hotlinks for the larger documents, such as related technical
memoranda, reports and papers, lead to other web sites where this
information is stashed. We apologize for the inconvenience this may
cause for users without Internet and World Wide Web access.

If you are an old hand and just want to build the distribution, you
might find the INSTALL file a useful shortcut. A descriptive list of all
files in the base directory of this distribution is in the README file.
A list of "significant" changes for the release is in the NEWS file.

If you're interested in helping us test pre-release versions of ntpd,
please look in .

\`configure' configures ntp 4.2.6p5 to adapt to many kinds of systems.

Usage: $0 [OPTION]... [VAR=VALUE]...

To assign environment variables (e.g., CC, CFLAGS...), specify them as
VAR=VALUE.  See below for descriptions of some of the useful variables.

Defaults for the options are specified in brackets.

Configuration:
  -h, --help              display this help and exit
      --help=short        display options specific to this package
      --help=recursive    display the short help of all the included packages
  -V, --version           display version information and exit
  -q, --quiet, --silent   do not print \`checking ...' messages
      --cache-file=FILE   cache test results in FILE [disabled]
  -C, --config-cache      alias for \`--cache-file=config.cache'
  -n, --no-create         do not create output files
      --srcdir=DIR        find the sources in DIR [configure dir or \`..']

Installation directories:
  --prefix=PREFIX         install architecture-independent files in PREFIX
                          [$ac_default_prefix]
  --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
                          [PREFIX]

By default, \`make install' will install all the files in
\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
an installation prefix other than \`$ac_default_prefix' using \`--prefix',
for instance \`--prefix=\$HOME'.

For better control, use the options below.

Fine tuning of the installation directories:
  --bindir=DIR            user executables [EPREFIX/bin]
  --sbindir=DIR           system admin executables [EPREFIX/sbin]
  --libexecdir=DIR        program executables [EPREFIX/libexec]

  --localstatedir=DIR     modifiable single-machine data [PREFIX/var]
  --libdir=DIR            object code libraries [EPREFIX/lib]
  --includedir=DIR        C header files [PREFIX/include]
  --oldincludedir=DIR     C header files for non-gcc [/usr/include]
  --datarootdir=DIR       read-only arch.-independent data root [PREFIX/share]

Some influential environment variables:
  CC          C compiler command
  CFLAGS      C compiler flags
  LDFLAGS     linker flags, e.g. -L if you have libraries in a
              nonstandard directory 
  LIBS        libraries to pass to the linker, e.g. -l
  CPPFLAGS    (Objective) C/C++ preprocessor flags, e.g. -I if
              you have headers in a nonstandard directory 
  CPP         C preprocessor
  YACC        The `Yet Another Compiler Compiler' implementation to use.
              Defaults to the first program found out of: `bison -y', `byacc',
              `yacc'.
  YFLAGS      The list of arguments that will be passed by default to $YACC.
              This script will default YFLAGS to the empty string to avoid a
              default value of `-d' given by some make applications.

Use these variables to override the choices made by `configure' or to help
it to find libraries and programs with nonstandard names/locations.

Report bugs to the package provider.

######################################################################
#
# Revision: mkver.bat
# Author:   Frederick Czajka
# Date:     02/10/2000
# Purpose:  Provide a NT Shell script to replace the perl script 
#           that replaced the UNIX mkver shell script.
#           
# 
#
# Notes:  I had two goals with this script one to only use native
#         NT Shell commands and two was too emulate the PERL style
#         output. This required some work for the DATE format as 
#         you will see and TIME was really tricky to get a format 
#         matching PERLs!
#
#
# Changes:
# 12/21/2009	Dave Hart
#				- packageinfo.sh uses prerelease= now not
#				  releasecandidate=
# 08/28/2009	Dave Hart	
#				- support for building using per-compiler subdirs of winnt
# 08/08/2006	Heiko Gerstung
#				- bugfixed point / rcpoint errors leading to a wrong
#				  version string 
#				- added a few cases for uppercase strings
# 03/09/2005	Heiko Gerstung
#				- added UTC offset to version time information
#				- bugfixed several issues preventing this script to be used on NT4 
#				- removed an obsolete warning
#
# 03/08/2005	Danny Mayer
#				- bugfixed NOBK label position
#
# 03/08/2005	Heiko Gerstung
#				- bugfixed BK detection and support for multiple ChangeSets 
#				
# 02/24/2005	Heiko Gerstung
#				- check if BK is installed and do not try to call it if not
#
#
# 02/03/2005	Heiko Gerstung
#				- now getting NTP version from version.m4 (not configure)
#				- added BK ChangeSet revision and Openssl-Indicator (-o) 
#				  to the version number
#				- major rework of the time and date recognition routines
#				  in order to reflect international settings and OS-
#				  dependand formats
#
######################################################################

Notes/Howtos:

If you spot an error stating that bk.exe could not be found or executed
although it is installed on your computer, you should try to add the path 
to your BK binary in your IDE configuration (for VisualStudio see 
Tools/Options/Directories/Executables).

Alternatively you can create a file called 'version' in the root path of 
your ntp source tree which holds a string that is added to the version number.

 This file contains the message definitions for the Win32
 syslog support messages for the nntp firewall
-------------------------------------------------------------------------
 HEADER SECTION

 The header section defines names and language identifiers for use
 by the message definitions later in this file. The MessageIdTypedef,
 SeverityNames, FacilityNames, and LanguageNames keywords are
 optional and not required.



 The MessageIdTypedef keyword gives a typedef name that is used in a
 type cast for each message code in the generated include file. Each
 message code appears in the include file with the format: #define
 name ((type) 0xnnnnnnnn) The default value for type is empty, and no
 type cast is generated. It is the programmer's responsibility to
 specify a typedef statement in the application source code to define
 the type. The type used in the typedef must be large enough to
 accomodate the entire 32-bit message code.



 The SeverityNames keyword defines the set of names that are allowed
 as the value of the Severity keyword in the message definition. The
 set is delimited by left and right parentheses. Associated with each
 severity name is a number that, when shifted left by 30, gives the
 bit pattern to logical-OR with the Facility value and MessageId
 value to form the full 32-bit message code. The default value of
 this keyword is:

 SeverityNames=(
   Success=0x0
   Informational=0x1
   Warning=0x2
   Error=0x3
   )

 Severity values occupy the high two bits of a 32-bit message code.
 Any severity value that does not fit in two bits is an error. The
 severity codes can be given symbolic names by following each value
 with :name


FacilityNames=(System=0x0:FACILITY_SYSTEM
               Runtime=0x2:FACILITY_RUNTIME
               Stubs=0x3:FACILITY_STUBS
               Io=0x4:FACILITY_IO_ERROR_CODE
              )

 The FacilityNames keyword defines the set of names that are allowed
 as the value of the Facility keyword in the message definition. The
 set is delimited by left and right parentheses. Associated with each
 facility name is a number that, when shift it left by 16 bits, gives
 the bit pattern to logical-OR with the Severity value and MessageId
 value to form the full 32-bit message code. The default value of
 this keyword is:

 FacilityNames=(
   System=0x0FF
   Application=0xFFF
   )

 Facility codes occupy the low order 12 bits of the high order
 16-bits of a 32-bit message code. Any facility code that does not
 fit in 12 bits is an error. This allows for 4,096 facility codes.
 The first 256 codes are reserved for use by the system software. The
 facility codes can be given symbolic names by following each value
 with :name


 The LanguageNames keyword defines the set of names that are allowed
 as the value of the Language keyword in the message definition. The
 set is delimited by left and right parentheses. Associated with each
 language name is a number and a file name that are used to name the
 generated resource file that contains the messages for that
 language. The number corresponds to the language identifier to use
 in the resource table. The number is separated from the file name
 with a colon. The initial value of LanguageNames is:

 LanguageNames=(English=1:MSG00001)

 Any new names in the source file which don't override the built-in
 names are added to the list of valid languages. This allows an
 application to support private languages with descriptive names.


-------------------------------------------------------------------------
 MESSAGE DEFINITION SECTION

 Following the header section is the body of the Message Compiler
 source file. The body consists of zero or more message definitions.
 Each message definition begins with one or more of the following
 statements:

 MessageId = [number|+number]
 Severity = severity_name
 Facility = facility_name
 SymbolicName = name

 The MessageId statement marks the beginning of the message
 definition. A MessageID statement is required for each message,
 although the value is optional. If no value is specified, the value
 used is the previous value for the facility plus one. If the value
 is specified as +number then the value used is the previous value
 for the facility, plus the number after the plus sign. Otherwise, if
 a numeric value is given, that value is used. Any MessageId value
 that does not fit in 16 bits is an error.

 The Severity and Facility statements are optional. These statements
 specify additional bits to OR into the final 32-bit message code. If
 not specified they default to the value last specified for a message
 definition. The initial values prior to processing the first message
 definition are:

 Severity=Success
 Facility=Application

 The value associated with Severity and Facility must match one of
 the names given in the FacilityNames and SeverityNames statements in
 the header section. The SymbolicName statement allows you to
 associate a C/C++ symbolic constant with the final 32-bit message
 code.

dnl	txc.tick	1	    Linux
dnl	(every / 10)	50	    WinNT - tickadj is roughly 500/hz
dnl	1000000L/hz	(nlist)     (Solaris && !ADJTIME_IS_ACCURATE),

#
# depsver.mf	included in Makefile.am for directories with .deps
#
# When building in the same directory with sources that change over
# time, such as when tracking using bk, the .deps files can become
# stale with respect to moved, deleted, or superceded headers.  Most
# commonly, this would exhibit as make reporting a failure to make a
# header file which is no longer in the location given.  To address
# this issue, we use a deps-ver file which is updated with each change
# that breaks old .deps files.  A copy of deps-ver is made into
# $(DEPDIR) if not already present.  If $(DEPDIR)/deps-ver is present
# with different contents than deps-ver, we make clean to ensure all
# .o files built before the incompatible change are rebuilt along with
# their updated .deps files, then remove $(DEPDIR) and recreate it as
# empty stubs.
#
# It is normal when configured with --disable-dependency-tracking for
# the DEPDIR to not have been created.  For this reason, we use the
# intermediate target .deps-ver, which invokes make recursively if
# DEPDIR exists.
#
# If you modify depsver.mf, please make the changes to the master
# copy, the one in sntp is copied by the bootstrap script from it.
#
# This comment block follows rather than leads the related code so that
# it stays with it in the generated Makefile.in and Makefile.

/*
 * This driver supports the Arbiter 1088A/B Satellite Controlled Clock.
 * The claimed accuracy of this clock is 100 ns relative to the PPS
 * output when receiving four or more satellites.
 *
 * The receiver should be configured before starting the NTP daemon, in
 * order to establish reliable position and operating conditions. It
 * does not initiate surveying or hold mode. For use with NTP, the
 * daylight savings time feature should be disables (D0 command) and the
 * broadcast mode set to operate in UTC (BU command).
 *
 * The timecode format supported by this driver is selected by the poll
 * sequence "B5", which initiates a line in the following format to be
 * repeated once per second until turned off by the "B0" poll sequence.
 *
 * Format B5 (24 ASCII printing characters):
 *
 * i yy ddd hh:mm:ss.000bbb  
 *
 *	on-time = 
 *	i = synchronization flag (' ' = locked, '?' = unlocked)
 *	yy = year of century
 *	ddd = day of year
 *	hh:mm:ss = hours, minutes, seconds
 *	.000 = fraction of second (not used)
 *	bbb = tailing spaces for fill
 *
 * The alarm condition is indicated by a '?' at i, which indicates the
 * receiver is not synchronized. In normal operation, a line consisting
 * of the timecode followed by the time quality character (TQ) followed
 * by the receiver status string (SR) is written to the clockstats file.
 * The time quality character is encoded in IEEE P1344 standard:
 *
 * Format TQ (IEEE P1344 estimated worst-case time quality)
 *
 *	0	clock locked, maximum accuracy
 *	F	clock failure, time not reliable
 *	4	clock unlocked, accuracy < 1 us
 *	5	clock unlocked, accuracy < 10 us
 *	6	clock unlocked, accuracy < 100 us
 *	7	clock unlocked, accuracy < 1 ms
 *	8	clock unlocked, accuracy < 10 ms
 *	9	clock unlocked, accuracy < 100 ms
 *	A	clock unlocked, accuracy < 1 s
 *	B	clock unlocked, accuracy < 10 s
 *
 * The status string is encoded as follows:
 *
 * Format SR (25 ASCII printing characters)
 *
 *	V=vv S=ss T=t P=pdop E=ee
 *
 *	vv = satellites visible
 *	ss = relative signal strength
 *	t = satellites tracked
 *	pdop = position dilution of precision (meters)
 *	ee = hardware errors
 *
 * If flag4 is set, an additional line consisting of the receiver
 * latitude (LA), longitude (LO), elevation (LH) (meters), and data
 * buffer (DB) is written to this file. If channel B is enabled for
 * deviation mode and connected to a 1-PPS signal, the last two numbers
 * on the line are the deviation and standard deviation averaged over
 * the last 15 seconds.

 * Kernel PLL/PPS state machine. This is used with the kernel PLL
 * modifications described in the documentation.
 *
 * If kernel support for the ntp_adjtime() system call is available, the
 * ntp_control flag is set. The ntp_enable and kern_enable flags can be
 * set at configuration time or run time using ntpdc. If ntp_enable is
 * false, the discipline loop is unlocked and no corrections of any kind
 * are made. If both ntp_control and kern_enable are set, the kernel
 * support is used as described above; if false, the kernel is bypassed
 * entirely and the daemon discipline used instead.
 *
 * There have been three versions of the kernel discipline code. The
 * first (microkernel) now in Solaris discipilnes the microseconds. The
 * second and third (nanokernel) disciplines the clock in nanoseconds.
 * These versions are identifed if the symbol STA_PLL is present in the
 * header file /usr/include/sys/timex.h. The third and current version
 * includes TAI offset and is identified by the symbol NTP_API with
 * value 4.
 *
 * Each PPS time/frequency discipline can be enabled by the atom driver
 * or another driver. If enabled, the STA_PPSTIME and STA_FREQ bits are
 * set in the kernel status word; otherwise, these bits are cleared.
 * These bits are also cleard if the kernel reports an error.
 *
 * If an external clock is present, the clock driver sets STA_CLK in the
 * status word. When the local clock driver sees this bit, it updates
 * via this routine, which then calls ntp_adjtime() with the STA_PLL bit
 * set to zero, in which case the system clock is not adjusted. This is
 * also a signal for the external clock driver to discipline the system
 * clock. Unless specified otherwise, all times are in seconds.

/*
 * This driver supports the Spectracom Model 8170 and Netclock/2 WWVB
 * Synchronized Clocks and the Netclock/GPS Master Clock. Both the WWVB
 * and GPS clocks have proven reliable sources of time; however, the
 * WWVB clocks have proven vulnerable to high ambient conductive RF
 * interference. The claimed accuracy of the WWVB clocks is 100 us
 * relative to the broadcast signal, while the claimed accuracy of the
 * GPS clock is 50 ns; however, in most cases the actual accuracy is
 * limited by the resolution of the timecode and the latencies of the
 * serial interface and operating system.
 *
 * The WWVB and GPS clocks should be configured for 24-hour display,
 * AUTO DST off, time zone 0 (UTC), data format 0 or 2 (see below) and
 * baud rate 9600. If the clock is to used as the source for the IRIG
 * Audio Decoder (refclock_irig.c in this distribution), it should be
 * configured for AM IRIG output and IRIG format 1 (IRIG B with
 * signature control). The GPS clock can be configured either to respond
 * to a 'T' poll character or left running continuously. 
 *
 * There are two timecode formats used by these clocks. Format 0, which
 * is available with both the Netclock/2 and 8170, and format 2, which
 * is available only with the Netclock/2, specially modified 8170 and
 * GPS.
 *
 * Format 0 (22 ASCII printing characters):
 *
 * i  ddd hh:mm:ss TZ=zz
 *
 *	on-time = first 
 *	hh:mm:ss = hours, minutes, seconds
 *	i = synchronization flag (' ' = in synch, '?' = out of synch)
 *
 * The alarm condition is indicated by other than ' ' at i, which occurs
 * during initial synchronization and when received signal is lost for
 * about ten hours.
 *
 * Format 2 (24 ASCII printing characters):
 *
 * iqyy ddd hh:mm:ss.fff ld
 *
 *	on-time = 
 *	i = synchronization flag (' ' = in synch, '?' = out of synch)
 *	q = quality indicator (' ' = locked, 'A'...'D' = unlocked)
 *	yy = year (as broadcast)
 *	ddd = day of year
 *	hh:mm:ss.fff = hours, minutes, seconds, milliseconds
 *
 * The alarm condition is indicated by other than ' ' at i, which occurs
 * during initial synchronization and when received signal is lost for
 * about ten hours. The unlock condition is indicated by other than ' '
 * at q.
 *
 * The q is normally ' ' when the time error is less than 1 ms and a
 * character in the set 'A'...'D' when the time error is less than 10,
 * 100, 500 and greater than 500 ms respectively. The l is normally ' ',
 * but is set to 'L' early in the month of an upcoming UTC leap second
 * and reset to ' ' on the first day of the following month. The d is
 * set to 'S' for standard time 'I' on the day preceding a switch to
 * daylight time, 'D' for daylight time and 'O' on the day preceding a
 * switch to standard time. The start bit of the first  is
 * synchronized to the indicated time as returned.
 *
 * This driver does not need to be told which format is in use - it
 * figures out which one from the length of the message. The driver
 * makes no attempt to correct for the intrinsic jitter of the radio
 * itself, which is a known problem with the older radios.
 *
 * PPS Signal Processing
 *
 * When PPS signal processing is enabled, and when the system clock has
 * been set by this or another driver and the PPS signal offset is
 * within 0.4 s of the system clock offset, the PPS signal replaces the
 * timecode for as long as the PPS signal is active. If for some reason
 * the PPS signal fails for one or more poll intervals, the driver
 * reverts to the timecode. If the timecode fails for one or more poll
 * intervals, the PPS signal is disconnected.
 *
 * Fudge Factors
 *
 * This driver can retrieve a table of quality data maintained
 * internally by the Netclock/2 clock. If flag4 of the fudge
 * configuration command is set to 1, the driver will retrieve this
 * table and write it to the clockstats file when the first timecode
 * message of a new day is received.
 *
 * PPS calibration fudge time 1: format 0 .003134, format 2 .004034

 * This is a hack to allow a machine to use its own system clock as a
 * reference clock, i.e., to free-run using no outside clock discipline
 * source. Note that the clock selection algorithm will not select this
 * driver unless all other sources of synchronization have been lost.
 * This is useful if you want to use NTP in an isolated environment
 * with no radio clock or NIST modem available. Pick a machine that you
 * figure has a good clock oscillator and configure it with this
 * driver. Set the clock using the best means available, like
 * eyeball-and-wristwatch. Then, point all the other machines at this
 * one or use broadcast (not multicast) mode to distribute time.
 *
 * Another application for this driver is if you want to use a
 * particular server's clock as the clock of last resort when all other
 * normal synchronization sources have gone away. This is especially
 * useful if that server has an ovenized oscillator. However, the
 * preferred was to do this is using orphan mode. See the documentation.
 *
 * A third application for this driver is when an external discipline
 * source is available, such as the NIST "lockclock" program, which
 * synchronizes the local clock via a telephone modem and the NIST
 * Automated Computer Time Service (ACTS), or the Digital Time
 * Synchronization Service (DTSS), which runs on DCE machines. In this
 * case the stratum should be set at zero, indicating a bona fide
 * stratum-1 source. Exercise some caution with this, since there is no
 * easy way to telegraph via NTP that something might be wrong in the
 * discipline source itself. In the case of DTSS, the local clock can
 * have a rather large jitter, depending on the interval between
 * corrections and the intrinsic frequency error of the clock
 * oscillator. In extreme cases, this can cause clients to exceed the
 * 128-ms slew window and drop off the NTP subnet.
 *
 * Fudge Factors
 *
 * If fudge flag1 is lit, the leap second bit is set in the peer
 * status word. It should be set early in the day of a leap second
 * event and set dark on the day after the event.
 *
 * Note the fudge time1 and time2 have been deprecated. The fudge time1
 * was intended to apply a bias offset. This can be done using the Unix
 * date command. The fudge time2 was intended to apply a bias frequency.
 * This can be done using the frequency file and/or the freq
 * configuration command.

/*
 * Audio IRIG-B/E demodulator/decoder
 *
 * This driver synchronizes the computer time using data encoded in
 * IRIG-B/E signals commonly produced by GPS receivers and other timing
 * devices. The IRIG signal is an amplitude-modulated carrier with
 * pulse-width modulated data bits. For IRIG-B, the carrier frequency is
 * 1000 Hz and bit rate 100 b/s; for IRIG-E, the carrier frequenchy is
 * 100 Hz and bit rate 10 b/s. The driver automatically recognizes which
 & format is in use.
 *
 * The driver requires an audio codec or sound card with sampling rate 8
 * kHz and mu-law companding. This is the same standard as used by the
 * telephone industry and is supported by most hardware and operating
 * systems, including Solaris, SunOS, FreeBSD, NetBSD and Linux. In this
 * implementation, only one audio driver and codec can be supported on a
 * single machine.
 *
 * The program processes 8000-Hz mu-law companded samples using separate
 * signal filters for IRIG-B and IRIG-E, a comb filter, envelope
 * detector and automatic threshold corrector. Cycle crossings relative
 * to the corrected slice level determine the width of each pulse and
 * its value - zero, one or position identifier.
 *
 * The data encode 20 BCD digits which determine the second, minute,
 * hour and day of the year and sometimes the year and synchronization
 * condition. The comb filter exponentially averages the corresponding
 * samples of successive baud intervals in order to reliably identify
 * the reference carrier cycle. A type-II phase-lock loop (PLL) performs
 * additional integration and interpolation to accurately determine the
 * zero crossing of that cycle, which determines the reference
 * timestamp. A pulse-width discriminator demodulates the data pulses,
 * which are then encoded as the BCD digits of the timecode.
 *
 * The timecode and reference timestamp are updated once each second
 * with IRIG-B (ten seconds with IRIG-E) and local clock offset samples
 * saved for later processing. At poll intervals of 64 s, the saved
 * samples are processed by a trimmed-mean filter and used to update the
 * system clock.
 *
 * An automatic gain control feature provides protection against
 * overdriven or underdriven input signal amplitudes. It is designed to
 * maintain adequate demodulator signal amplitude while avoiding
 * occasional noise spikes. In order to assure reliable capture, the
 * decompanded input signal amplitude must be greater than 100 units and
 * the codec sample frequency error less than 250 PPM (.025 percent).
 *
 * Monitor Data
 *
 * The timecode format used for debugging and data recording includes
 * data helpful in diagnosing problems with the IRIG signal and codec
 * connections. The driver produces one line for each timecode in the
 * following format:
 *
 * 00 00 98 23 19:26:52 2782 143 0.694 10 0.3 66.5 3094572411.00027
 *
 * If clockstats is enabled, the most recent line is written to the
 * clockstats file every 64 s. If verbose recording is enabled (fudge
 * flag 4) each line is written as generated.
 *
 * The first field containes the error flags in hex, where the hex bits
 * are interpreted as below. This is followed by the year of century,
 * day of year and time of day. Note that the time of day is for the
 * previous minute, not the current time. The status indicator and year
 * are not produced by some IRIG devices and appear as zeros. Following
 * these fields are the carrier amplitude (0-3000), codec gain (0-255),
 * modulation index (0-1), time constant (4-10), carrier phase error
 * +-.5) and carrier frequency error (PPM). The last field is the on-
 * time timestamp in NTP format.
 *
 * The error flags are defined as follows in hex:
 *
 * x01	Low signal. The carrier amplitude is less than 100 units. This
 *	is usually the result of no signal or wrong input port.
 * x02	Frequency error. The codec frequency error is greater than 250
 *	PPM. This may be due to wrong signal format or (rarely)
 *	defective codec.
 * x04	Modulation error. The IRIG modulation index is less than 0.5.
 *	This is usually the result of an overdriven codec, wrong signal
 *	format or wrong input port.
 * x08	Frame synch error. The decoder frame does not match the IRIG
 *	frame. This is usually the result of an overdriven codec, wrong
 *	signal format or noisy IRIG signal. It may also be the result of
 *	an IRIG signature check which indicates a failure of the IRIG
 *	signal synchronization source.
 * x10	Data bit error. The data bit length is out of tolerance. This is
 *	usually the result of an overdriven codec, wrong signal format
 *	or noisy IRIG signal.
 * x20	Seconds numbering discrepancy. The decoder second does not match
 *	the IRIG second. This is usually the result of an overdriven
 *	codec, wrong signal format or noisy IRIG signal.
 * x40	Codec error (overrun). The machine is not fast enough to keep up
 *	with the codec.
 * x80	Device status error (Spectracom).
 *
 *
 * Once upon a time, an UltrSPARC 30 and Solaris 2.7 kept the clock
 * within a few tens of microseconds relative to the IRIG-B signal.
 * Accuracy with IRIG-E was about ten times worse. Unfortunately, Sun
 * broke the 2.7 audio driver in 2.8, which has a 10-ms sawtooth
 * modulation.
 *
 * Unlike other drivers, which can have multiple instantiations, this
 * one supports only one. It does not seem likely that more than one
 * audio codec would be useful in a single machine. More than one would
 * probably chew up too much CPU time anyway.
 *
 * Fudge factors
 *
 * Fudge flag4 causes the dubugging output described above to be
 * recorded in the clockstats file. Fudge flag2 selects the audio input
 * port, where 0 is the mike port (default) and 1 is the line-in port.
 * It does not seem useful to select the compact disc player port. Fudge
 * flag3 enables audio monitoring of the input signal. For this purpose,
 * the monitor gain is set t a default value. Fudgetime2 is used as a
 * frequency vernier for broken codec sample frequency.
 *
 * Alarm codes
 *
 * CEVNT_BADTIME	invalid date or time
 * CEVNT_TIMEOUT	no IRIG data since last poll

 * --------------------------------------------------------------------------
 * Reg Clemens (June 2009)
 * BUG[1220] OK, big patch, but mostly done mechanically.  Change direct calls to write
 * to clockstats to a call to oncore_log, which now calls the old routine plus msyslog.
 * Have to set the LOG_LEVELS of the calls for msyslog, and this was done by hand. New
 * routine oncore_log.
 * --------------------------------------------------------------------------
 * Reg Clemens (June 2009)
 * BUG[1218] The comment on where the oncore driver gets its input file does not
 * agree with the code.  Change the comment.
 * --------------------------------------------------------------------------
 * Reg Clemens (June 2009)
 * change exit statements to return(0) in main program.  I had assumed that if the
 * PPS driver did not start for some reason, we shuould stop NTPD itelf.  Others
 * disagree.  We now give an ERR log message and stop this driver.
 * --------------------------------------------------------------------------
 * Reg Clemens (June 2009)
 * A bytes available message for the input subsystem (Debug message).
 * --------------------------------------------------------------------------
 * Reg Clemens (Nov 2008)
 * This code adds a message for TRAIM messages.  Users often worry about the
 * driver not starting up, and it is often because of signal strength being low.
 * Low signal strength will give TRAIM messages.
 * --------------------------------------------------------------------------
 * Reg Clemens (Nov 2008)
 * Add waiting on Almanac Message.
 * --------------------------------------------------------------------------
 * Reg Clemens (Nov 2008)
 * Add back in @@Bl code to do the @@Bj/@@Gj that is in later ONCOREs
 * LEAP SECONDS: All of the ONCORE receivers, VP -> M12T have the @@Bj command
 * that says 'Leap Pending'.  As documented it only becomes true in the month
 * before the leap second is to be applied, but in practice at least some of
 * the receivers turn this indicator on as soon as the message is posted, which
 * can be 6months early.  As such, we use the Bj command to turn on the
 * instance->pp->leap indicator but only run this test in December and June for
 * updates on 1Jan and 1July.
 *
 * The @@Gj command exists in later ONCOREs, and it gives the exact date
 * and size of the Leap Update.  It can be emulated in the VP using the @@Bl
 * command which reads the raw Satellite Broadcast Messages.
 * We use these two commands to print informative messages in the clockstats
 * file once per day as soon as the message appears on the satellites.
 * --------------------------------------------------------------------------
 * Reg Clemens (Feb 2006)
 * Fix some gcc4 compiler complaints
 * Fix possible segfault in oncore_init_shmem
 * change all (possible) fprintf(stderr, to record_clock_stats
 * Apply patch from Russell J. Yount  Fixed (new) MT12+T UTC not correct
 *   immediately after new Almanac Read.
 * Apply patch for new PPS implementation by Rodolfo Giometti 
 *   now code can use old Ulrich Windl  or
 *   the new one.  Compiles depending on timepps.h seen.
 * --------------------------------------------------------------------------
 * Luis Batanero Guerrero  (Dec 2005) Patch for leap seconds
 * (the oncore driver was setting the wrong ntpd variable)
 * --------------------------------------------------------------------------
 * Reg.Clemens (Mar 2004)
 * Support for interfaces other than PPSAPI removed, for Solaris, SunOS,
 * SCO, you now need to use one of the timepps.h files in the root dir.
 * this driver will 'grab' it for you if you dont have one in /usr/include
 * --------------------------------------------------------------------------
 * This code uses the two devices
 *	/dev/oncore.serial.n
 *	/dev/oncore.pps.n
 * which may be linked to the same device.
 * and can read initialization data from the file
 *	/etc/ntp.oncoreN, /etc/ntp.oncore.N, or /etc/ntp.oncore, where
 *	n or N are the unit number, viz 127.127.30.N.
 * --------------------------------------------------------------------------
 * Reg.Clemens  Sep98.
 *  Original code written for FreeBSD.
 *  With these mods it works on FreeBSD, SunOS, Solaris and Linux
 *    (SunOS 4.1.3 + ppsclock)
 *    (Solaris7 + MU4)
 *    (RedHat 5.1 2.0.35 + PPSKit, 2.1.126 + or later).
 *
 *  Lat,Long,Ht, cable-delay, offset, and the ReceiverID (along with the
 *  state machine state) are printed to CLOCKSTATS if that file is enabled
 *  in /etc/ntp.conf.
 *
 * --------------------------------------------------------------------------
 *
 * According to the ONCORE manual (TRM0003, Rev 3.2, June 1998, page 3.13)
 * doing an average of 10000 valid 2D and 3D fixes is what the automatic
 * site survey mode does.  Looking at the output from the receiver
 * it seems like it is only using 3D fixes.
 * When we do it ourselves, take 10000 3D fixes.

	   The Windows port of ntpd arranges to return duplicate handles for

 *    (1) NO RESET, Read Position, delays from data file, lock it in, go to 0D mode.
 *    (2) NO RESET, Read Delays from data file, do SITE SURVEY to get position,
 *		    lock this in, go to 0D mode.
 *    (3) HARD RESET, Read Position, delays from data file, lock it in, go to 0D mode.
 *    (4) HARD RESET, Read Delays from data file, do SITE SURVEY to get position,
 *		    lock this in, go to 0D mode.
 *     NB. If a POSITION is specified in the config file with mode=(2,4) [SITE SURVEY]
 *	   then this position is set as the INITIAL position of the ONCORE.
 *	   This can reduce the time to first fix.
 * -------------------------------------------------------------------------------
 * Note that an Oncore UT without a battery backup retains NO information if it is
 *   power cycled, with a Battery Backup it remembers the almanac, etc.
 * For an Oncore VP, there is an eeprom that will contain this data, along with the
 *   option of Battery Backup.
 * So a UT without Battery Backup is equivalent to doing a HARD RESET on each
 *   power cycle, since there is nowhere to store the data.
 * -------------------------------------------------------------------------------
 *
 * If we open one or the other of the files, we read it looking for
 *   MODE, LAT, LON, (HT, HTGPS, HTMSL), DELAY, OFFSET, ASSERT, CLEAR, HARDPPS,
 *   STATUS, POSN3D, POSN2D, CHAN, TRAIM
 * then initialize using method MODE.  For Mode = (1,3) all of (LAT, LON, HT) must
 *   be present or mode reverts to (2,4).
 *
 * Read input file.
 *
 *	# is comment to end of line
 *	= allowed between 1st and 2nd fields.
 *
 *	Expect to see one line with 'MODE' as first field, followed by an integer
 *	   in the range 0-4 (default = 4).
 *
 *	Expect to see two lines with 'LONG', 'LAT' followed by 1-3 fields.
 *	All numbers are floating point.
 *		DDD.ddd
 *		DDD  MMM.mmm
 *		DDD  MMM  SSS.sss
 *
 *	Expect to see one line with 'HT' as first field,
 *	   followed by 1-2 fields.  First is a number, the second is 'FT' or 'M'
 *	   for feet or meters.	HT is the height above the GPS ellipsoid.
 *	   If the receiver reports height in both GPS and MSL, then we will report
 *	   the difference GPS-MSL on the clockstats file.
 *
 *	There is an optional line, starting with DELAY, followed
 *	   by 1 or two fields.	The first is a number (a time) the second is
 *	   'MS', 'US' or 'NS' for miliseconds, microseconds or nanoseconds.
 *	    DELAY  is cable delay, typically a few tens of ns.
 *
 *	There is an optional line, starting with OFFSET, followed
 *	   by 1 or two fields.	The first is a number (a time) the second is
 *	   'MS', 'US' or 'NS' for miliseconds, microseconds or nanoseconds.
 *	   OFFSET is the offset of the PPS pulse from 0. (only fully implemented
 *		with the PPSAPI, we need to be able to tell the Kernel about this
 *		offset if the Kernel PLL is in use, but can only do this presently
 *		when using the PPSAPI interface.  If not using the Kernel PLL,
 *		then there is no problem.
 *
 *	There is an optional line, with either ASSERT or CLEAR on it, which
 *	   determine which transition of the PPS signal is used for timing by the
 *	   PPSAPI.  If neither is present, then ASSERT is assumed.
 *	   ASSERT/CLEAR can also be set with FLAG2 of the ntp.conf input.
 *	   For Flag2, ASSERT=0, and hence is default.
 *
 *	There is an optional line, with HARDPPS on it.	Including this line causes
 *	   the PPS signal to control the kernel PLL.
 *	   HARDPPS can also be set with FLAG3 of the ntp.conf input.
 *	   For Flag3, 0 is disabled, and the default.
 *
 *	There are three options that have to do with using the shared memory option.
 *	   First, to enable the option there must be a SHMEM line with a file name.
 *	   The file name is the file associated with the shared memory.
 *
 *	In shared memory, there is one 'record' for each returned variable.
 *	For the @@Ea data there are three 'records' containing position data.
 *	   There will always be data in the record corresponding to the '0D' @@Ea record,
 *	   and the user has a choice of filling the '3D' record by specifying POSN3D,
 *	   or the '2D' record by specifying POSN2D.  In either case the '2D' or '3D'
 *	   record is filled once every 15s.
 *
 *	Two additional variables that can be set are CHAN and TRAIM.  These should be
 *	   set correctly by the code examining the @@Cj record, but we bring them out here
 *	   to allow the user to override either the # of channels, or the existence of TRAIM.
 *	   CHAN expects to be followed by in integer: 6, 8, or 12. TRAIM expects to be
 *	   followed by YES or NO.
 *
 *	There is an optional line with MASK on it followed by one integer field in the
 *	   range 0 to 89. This sets the satellite mask angle and will determine the minimum
 *	   elevation angle for satellites to be tracked by the receiver. The default value
 *	   is 10 deg for the VP and 0 deg for all other receivers.
 *
 * So acceptable input would be
 *	# these are my coordinates (RWC)
 *	LON  -106 34.610
 *	LAT    35 08.999
 *	HT	1589	# could equally well say HT 5215 FT
 *	DELAY  60 ns

/*
 * This driver supports the TRAK 8810/8820 GPS Station Clock. The claimed
 * accuracy at the 1-pps output is 200-300 ns relative to the broadcast
 * signal; however, in most cases the actual accuracy is limited by the
 * precision of the timecode and the latencies of the serial interface
 * and operating system.
 *
 * For best accuracy, this radio requires the LDISC_ACTS line
 * discipline, which captures a timestamp at the '*' on-time character
 * of the timecode. Using this discipline the jitter is in the order of
 * 1 ms and systematic error about 0.5 ms. If unavailable, the buffer
 * timestamp is used, which is captured at the \r ending the timecode
 * message. This introduces a systematic error of 23 character times, or
 * about 24 ms at 9600 bps, together with a jitter well over 8 ms on Sun
 * IPC-class machines.
 *
 * Using the memus, the radio should be set for 9600 bps, one stop bit
 * and no parity. It should be set to operate in computer (no echo)
 * mode. The timecode format includes neither the year nor leap-second
 * warning. No provisions are included in this preliminary version of
 * the driver to read and record detailed internal radio status.
 *
 * In operation, this driver sends a RQTS\r request to the radio at
 * initialization in order to put it in continuous time output mode. The
 * radio then sends the following message once each second:
 *
 *	*RQTS U,ddd:hh:mm:ss.0,q
 *
 *	on-time = '*' *	ddd = day of year
 *	hh:mm:ss = hours, minutes, seconds
 *	q = quality indicator (phase error), 0-6:
 * 		0 > 20 us
 *		6 > 10 us
 *		5 > 1 us
 *		4 > 100 ns
 *		3 > 10 ns
 *		2 < 10 ns
 *
 * The alarm condition is indicated by '0' at Q, which means the radio
 * has a phase error than 20 usec relative to the broadcast time. The
 * absence of year, DST and leap-second warning in this format is also
 * alarming.
 *
 * The continuous time mode is disabled using the RQTX request,
 * following which the radio sends a RQTX DONE response. In the
 * normal mode, other control and status requests are effective,
 * including the leap-second status request RQLS. The radio responds
 * wtih RQLS yy,mm,dd, where yy,mm,dd are the year, month and
 * day. Presumably, this gives the epoch of the next leap second,
 * RQLS 00,00,00 if none is specified in the GPS message. Specified in
 * this form, the information is generally useless and is ignored by
 * the driver.
 *
 * Fudge Factors
 *
 * There are no special fudge factors other than the generic.

THIS CODE IS SUPPLIED AS IS, WITH NO WARRANTY OF ANY KIND.  USE AT
YOUR OWN RISK.

Orginally developed and used with ntp3-5.85 by Derek Mulcahy.

Built against ntp3-5.90 on Solaris 2.5 using gcc 2.7.2.

This code may be freely copied and used and incorporated in other
systems providing the disclaimer and notice of authorship are
reproduced.

-------------------------------------------------------------------------------

Nigel's notes:

1) Called tcgetattr() before modifying, so that fields correctly initialised
   for all operating systems

2) Altered parsing of timestamp line so that it copes with fields which are
   not always ASCII digits (e.g. status field when battery low)

-------------------------------------------------------------------------------

Christopher's notes:

MAJOR CHANGES SINCE V1.2 
========================
 1) Applied patch by Andrey Bray 
    2001-02-17 comp.protocols.time.ntp

 2) Added WWVB support via clock mode command, localtime/UTC time configured
    via flag1=(0=UTC, 1=localtime)

 3) Added ignore resync request via flag2=(0=resync, 1=ignore resync)

 4) Added simplified conversion from localtime to UTC with dst/bst translation

 5) Added average signal quality poll

 6) Fixed a badformat error when no code is available due to stripping 
    \n & \r's 

 7) Fixed a badformat error when clearing lencode & memset a_lastcode in poll
    routine

 8) Lots of code cleanup, including standardized DEBUG macros and removal 
    of unused code 

-------------------------------------------------------------------------------

Author's original note:

I enclose my ntp driver for the Galleon Systems Arc MSF receiver.

It works (after a fashion) on both Solaris-1 and Solaris-2.

I am currently using ntp3-5.85.  I have been running the code for
about 7 months without any problems.  Even coped with the change to BST!

I had to do some funky things to read from the clock because it uses the
power from the receive lines to drive the transmit lines.  This makes the
code look a bit stupid but it works.  I also had to put in some delays to
allow for the turnaround time from receive to transmit.  These delays
are between characters when requesting a time stamp so that shouldn't affect
the results too drastically.

...

The bottom line is that it works but could easily be improved.  You are
free to do what you will with the code.  I haven't been able to determine
how good the clock is.  I think that this requires a known good clock
to compare it against.

-------------------------------------------------------------------------------

Damon's notes for adjustments:

MAJOR CHANGES SINCE V1.0
========================
 1) Removal of pollcnt variable that made the clock go permanently
    off-line once two time polls failed to gain responses.

 2) Avoiding (at least on Solaris-2) terminal becoming the controlling
    terminal of the process when we do a low-level open().

 3) Additional logic (conditional on ARCRON_LEAPSECOND_KEEN being
    defined) to try to resync quickly after a potential leap-second
    insertion or deletion.

 4) Code significantly slimmer at run-time than V1.0.


GENERAL
=======

 1) The C preprocessor symbol to have the clock built has been changed
    from ARC to ARCRON_MSF to CLOCK_ARCRON_MSF to minimise the
    possiblity of clashes with other symbols in the future.

 2) PRECISION should be -4/-5 (63ms/31ms) for the following reasons:

     a) The ARC documentation claims the internal clock is (only)
	accurate to about 20ms relative to Rugby (plus there must be
	noticable drift and delay in the ms range due to transmission
	delays and changing atmospheric effects).  This clock is not
	designed for ms accuracy as NTP has spoilt us all to expect.

     b) The clock oscillator looks like a simple uncompensated quartz
	crystal of the sort used in digital watches (ie 32768Hz) which
	can have large temperature coefficients and drifts; it is not
	clear if this oscillator is properly disciplined to the MSF
	transmission, but as the default is to resync only once per
	*day*, we can imagine that it is not, and is free-running.  We
	can minimise drift by resyncing more often (at the cost of
	reduced battery life), but drift/wander may still be
	significant.

     c) Note that the bit time of 3.3ms adds to the potential error in
	the the clock timestamp, since the bit clock of the serial link
	may effectively be free-running with respect to the host clock
	and the MSF clock.  Actually, the error is probably 1/16th of
	the above, since the input data is probably sampled at at least
	16x the bit rate.

    By keeping the clock marked as not very precise, it will have a
    fairly large dispersion, and thus will tend to be used as a
    `backup' time source and sanity checker, which this clock is
    probably ideal for.  For an isolated network without other time
    sources, this clock can probably be expected to provide *much*
    better than 1s accuracy, which will be fine.

    By default, PRECISION is set to -4, but experience, especially at a
    particular geographic location with a particular clock, may allow
    this to be altered to -5.  (Note that skews of +/- 10ms are to be
    expected from the clock from time-to-time.)  This improvement of
    reported precision can be instigated by setting flag3 to 1, though
    the PRECISION will revert to the normal value while the clock
    signal quality is unknown whatever the flag3 setting.

    IN ANY CASE, BE SURE TO SET AN APPROPRIATE FUDGE FACTOR TO REMOVE
    ANY RESIDUAL SKEW, eg:

	server 127.127.27.0 # ARCRON MSF radio clock unit 0.
	# Fudge timestamps by about 20ms.
	fudge 127.127.27.0 time1 0.020

    You will need to observe your system's behaviour, assuming you have
    some other NTP source to compare it with, to work out what the
    fudge factor should be.  For my Sun SS1 running SunOS 4.1.3_U1 with
    my MSF clock with my distance from the MSF transmitter, +20ms
    seemed about right, after some observation.

 3) REFID has been made "MSFa" to reflect the MSF time source and the
    ARCRON receiver.

 4) DEFAULT_RESYNC_TIME is the time in seconds (by default) before
    forcing a resync since the last attempt.  This is picked to give a
    little less than an hour between resyncs and to try to avoid
    clashing with any regular event at a regular time-past-the-hour
    which might cause systematic errors.

    The INITIAL_RESYNC_DELAY is to avoid bothering the clock and
    running down its batteries unnecesarily if ntpd is going to crash
    or be killed or reconfigured quickly.  If ARCRON_KEEN is defined
    then this period is long enough for (with normal polling rates)
    enough time samples to have been taken to allow ntpd to sync to
    the clock before the interruption for the clock to resync to MSF.
    This avoids ntpd syncing to another peer first and then
    almost immediately hopping to the MSF clock.

    The RETRY_RESYNC_TIME is used before rescheduling a resync after a
    resync failed to reveal a statisfatory signal quality (too low or
    unknown).

 5) The clock seems quite jittery, so I have increased the
    median-filter size from the typical (previous) value of 3.  I
    discard up to half the results in the filter.  It looks like maybe
    1 sample in 10 or so (maybe less) is a spike, so allow the median
    filter to discard at least 10% of its entries or 1 entry, whichever
    is greater.

 6) Sleeping *before* each character sent to the unit to allow required
    inter-character time but without introducting jitter and delay in
    handling the response if possible.

 7) If the flag ARCRON_KEEN is defined, take time samples whenever
    possible, even while resyncing, etc.  We rely, in this case, on the
    clock always giving us a reasonable time or else telling us in the
    status byte at the end of the timestamp that it failed to sync to
    MSF---thus we should never end up syncing to completely the wrong
    time.

 8) If the flag ARCRON_OWN_FILTER is defined, use own versions of
    refclock median-filter routines to get round small bug in 3-5.90
    code which does not return the median offset. XXX Removed this
    bit due NTP Version 4 upgrade - dlm.

 9) We would appear to have a year-2000 problem with this clock since
    it returns only the two least-significant digits of the year.  But
    ntpd ignores the year and uses the local-system year instead, so
    this is in fact not a problem.  Nevertheless, we attempt to do a
    sensible thing with the dates, wrapping them into a 100-year
    window.

 10)Logs stats information that can be used by Derek's Tcl/Tk utility
    to show the status of the clock.

 11)The clock documentation insists that the number of bits per
    character to be sent to the clock, and sent by it, is 11, including
    one start bit and two stop bits.  The data format is either 7+even
    or 8+none.


TO-DO LIST
==========

  * Eliminate use of scanf(), and maybe sprintf().

  * Allow user setting of resync interval to trade battery life for
    accuracy; maybe could be done via fudge factor or unit number.

  * Possibly note the time since the last resync of the MSF clock to
    MSF as the age of the last reference timestamp, ie trust the
    clock's oscillator not very much...

  * Add very slow auto-adjustment up to a value of +/- time2 to correct
    for long-term errors in the clock value (time2 defaults to 0 so the
    correction would be disabled by default).

  * Consider trying to use the tty_clk/ppsclock support.

  * Possibly use average or maximum signal quality reported during
    resync, rather than just the last one, which may be atypical.

/* These notes seem also to apply usefully to the ARCRON clock. */

/* The HKW clock module is a radio receiver tuned into the Rugby */
/* MSF time signal tranmitted on 60 kHz. The clock module connects */
/* to the computer via a serial line and transmits the time encoded */
/* in 15 bytes at 300 baud 7 bits two stop bits even parity */

/* Clock communications, from the datasheet */
/* All characters sent to the clock are echoed back to the controlling */
/* device. */
/* Transmit time/date information */
/* syntax ASCII o */
/* Character o may be replaced if neccesary by a character whose code */
/* contains the lowest four bits f(hex) eg */
/* syntax binary: xxxx1111 00001101 */

/* DHD note:
You have to wait for character echo + 10ms before sending next character.
*/

/* The clock replies to this command with a sequence of 15 characters */
/* which contain the complete time and a final  making 16 characters */
/* in total. */
/* The RC computer clock will not reply immediately to this command because */
/* the start bit edge of the first reply character marks the beginning of */
/* the second. So the RC Computer Clock will reply to this command at the */
/* start of the next second */
/* The characters have the following meaning */
/* 1. hours tens   */
/* 2. hours units  */
/* 3. minutes tens */
/* 4. minutes units */
/* 5. seconds tens  */
/* 6. seconds units */
/* 7. day of week 1-monday 7-sunday */
/* 8. day of month tens */
/* 9. day of month units */
/* 10. month tens */
/* 11. month units */
/* 12. year tens */
/* 13. year units */
/* 14. BST/UTC status */
/*	bit 7	parity */
/*	bit 6	always 0 */
/*	bit 5	always 1 */
/*	bit 4	always 1 */
/*	bit 3	always 0 */
/*	bit 2	=1 if UTC is in effect, complementary to the BST bit */
/*	bit 1	=1 if BST is in effect, according to the BST bit     */
/*	bit 0	BST/UTC change impending bit=1 in case of change impending */
/* 15. status */
/*	bit 7	parity */
/*	bit 6	always 0 */
/*	bit 5	always 1 */
/*	bit 4	always 1 */
/*	bit 3	=1 if low battery is detected */
/*	bit 2	=1 if the very last reception attempt failed and a valid */
/*		time information already exists (bit0=1) */
/*		=0 if the last reception attempt was successful */
/*	bit 1	=1 if at least one reception since 2:30 am was successful */
/*		=0 if no reception attempt since 2:30 am was successful */
/*	bit 0	=1 if the RC Computer Clock contains valid time information */
/*		This bit is zero after reset and one after the first */
/*		successful reception attempt */

/* DHD note:
Also note g command which confirms that a resync is in progress, and
if so what signal quality (0--5) is available.
Also note h command which starts a resync to MSF signal.

 *
 * 1. Added support for alternate PPS schemes, with code mostly

 *    This code runs on SunOS 4.1.3 with ppsclock-1.6a1 and Solaris 7.

/*
 * This driver supports the Heath GC-1000 Most Accurate Clock, with
 * RS232C Output Accessory. This is a WWV/WWVH receiver somewhat less
 * robust than other supported receivers. Its claimed accuracy is 100 ms
 * when actually synchronized to the broadcast signal, but this doesn't
 * happen even most of the time, due to propagation conditions, ambient
 * noise sources, etc. When not synchronized, the accuracy is at the
 * whim of the internal clock oscillator, which can wander into the
 * sunset without warning. Since the indicated precision is 100 ms,
 * expect a host synchronized only to this thing to wander to and fro,
 * occasionally being rudely stepped when the offset exceeds the default
 * clock_max of 128 ms. 
 *
 * There were two GC-1000 versions supported by this driver. The original
 * GC-1000 with RS-232 output first appeared in 1983, but dissapeared
 * from the market a few years later. The GC-1001 II with RS-232 output
 * first appeared circa 1990, but apparently is no longer manufactured.
 * The two models differ considerably, both in interface and commands.
 * The GC-1000 has a pseudo-bipolar timecode output triggered by a RTS
 * transition. The timecode includes both the day of year and time of
 * day. The GC-1001 II has a true bipolar output and a complement of
 * single character commands. The timecode includes only the time of
 * day.
 *
 * The GC-1001 II was apparently never tested and, based on a Coverity
 * scan, apparently never worked [Bug 689].  Related code has been disabled.
 *
 * GC-1000
 *
 * The internal DIPswitches should be set to operate in MANUAL mode. The
 * external DIPswitches should be set to GMT and 24-hour format.
 *
 * In MANUAL mode the clock responds to a rising edge of the request to
 * send (RTS) modem control line by sending the timecode. Therefore, it
 * is necessary that the operating system implement the TIOCMBIC and
 * TIOCMBIS ioctl system calls and TIOCM_RTS control bit. Present
 * restrictions require the use of a POSIX-compatible programming
 * interface, although other interfaces may work as well.
 *
 * A simple hardware modification to the clock can be made which
 * prevents the clock hearing the request to send (RTS) if the HI SPEC
 * lamp is out. Route the HISPEC signal to the tone decoder board pin
 * 19, from the display, pin 19. Isolate pin 19 of the decoder board
 * first, but maintain connection with pin 10. Also isolate pin 38 of
 * the CPU on the tone board, and use half an added 7400 to gate the
 * original signal to pin 38 with that from pin 19.
 *
 * The clock message consists of 23 ASCII printing characters in the
 * following format:
 *
 * hh:mm:ss.f AM  dd/mm/yr
 *
 *	hh:mm:ss.f = hours, minutes, seconds
 *	f = deciseconds ('?' when out of spec)
 *	AM/PM/bb = blank in 24-hour mode
 *	dd/mm/yr = day, month, year
 *
 * The alarm condition is indicated by '?', rather than a digit, at f.
 * Note that 0?:??:??.? is displayed before synchronization is first
 * established and hh:mm:ss.? once synchronization is established and
 * then lost again for about a day.
 *
 * GC-1001 II
 *
 * Commands consist of a single letter and are case sensitive. When
 * enterred in lower case, a description of the action performed is
 * displayed. When enterred in upper case the action is performed.
 * Following is a summary of descriptions as displayed by the clock:
 *
 * The clock responds with a command The 'A' command returns an ASCII
 * local time string:  HH:MM:SS.T xx, where
 *
 *	HH = hours
 *	MM = minutes
 *	SS = seconds
 *	T = tenths-of-seconds
 *	xx = 'AM', 'PM', or '  '
 *	 = carriage return
 *
 * The 'D' command returns 24 pairs of bytes containing the variable
 * divisor value at the end of each of the previous 24 hours. This
 * allows the timebase trimming process to be observed.  UTC hour 00 is
 * always returned first. The first byte of each pair is the high byte
 * of (variable divisor * 16); the second byte is the low byte of
 * (variable divisor * 16). For example, the byte pair 3C 10 would be
 * returned for a divisor of 03C1 hex (961 decimal).
 *
 * The 'I' command returns:  | TH | TL | ER | DH | DL | U1 | I1 | I2 | ,
 * where
 *
 *	TH = minutes since timebase last trimmed (high byte)
 *	TL = minutes since timebase last trimmed (low byte)
 *	ER = last accumulated error in 1.25 ms increments
 *	DH = high byte of (current variable divisor * 16)
 *	DL = low byte of (current variable divisor * 16)
 *	U1 = UT1 offset (/.1 s):  | + | 4 | 2 | 1 | 0 | 0 | 0 | 0 |
 *	I1 = information byte 1:  | W | C | D | I | U | T | Z | 1 | ,
 *	     where
 *
 *		W = set by WWV(H)
 *		C = CAPTURE LED on
 *		D = TRIM DN LED on
 *		I = HI SPEC LED on
 *		U = TRIM UP LED on
 *		T = DST switch on
 *		Z = UTC switch on
 *		1 = UT1 switch on
 *
 *	I2 = information byte 2:  | 8 | 8 | 4 | 2 | 1 | D | d | S | ,
 *	     where
 *
 *		8, 8, 4, 2, 1 = TIME ZONE switch settings
 *		D = DST bit (#55) in last-received frame
 *		d = DST bit (#2) in last-received frame
 *		S = clock is in simulation mode
 *
 * The 'P' command returns 24 bytes containing the number of frames
 * received without error during UTC hours 00 through 23, providing an
 * indication of hourly propagation.  These bytes are updated each hour
 * to reflect the previous 24 hour period.  UTC hour 00 is always
 * returned first.
 *
 * The 'T' command returns the UTC time:  | HH | MM | SS | T0 | , where
 *	HH = tens-of-hours and hours (packed BCD)
 *	MM = tens-of-minutes and minutes (packed BCD)
 *	SS = tens-of-seconds and seconds (packed BCD)
 *	T = tenths-of-seconds (BCD)
 *
 * Fudge Factors
 *
 * A fudge time1 value of .04 s appears to center the clock offset
 * residuals. The fudge time2 parameter is the local time offset east of
 * Greenwich, which depends on DST. Sorry about that, but the clock
 * gives no hint on what the DIPswitches say.

** The datum_pts_receive callback function is handled differently from the

** request message to the Datum Programmable Time System. Then, ntpd
** waits on a select() call to receive data back. The datum_pts_receive()
** function is called as data comes back. We expect a seven byte time
** code to be returned but the datum_pts_receive() function may only get
** a few bytes passed to it at a time. In other words, this routine may
** get called by the io stuff in ntpd a few times before we get all seven
** bytes. Once the last byte is received, we process it and then pass the
** new time measurement to ntpd for updating the system time. For now,
** there is no 3 state filtering done on the time measurements. The
** jitter may be a little high but at least for its current use, it is not
** a problem. We have tried to keep things as simple as possible. This
** clock should not jitter more than 1 or 2 mseconds at the most once
** things settle down. It is important to get the right drift calibrated
** in the ntpd.drift file as well as getting the right tick set up right
** using tickadj for SUNs. Tickadj is not used for the HP but you need to
** remember to bring up the adjtime daemon because HP does not support

 * variables in a state analogous to an actual peer and pass reference

 * refclock_unpeer() are called to initialize and terminate reference
 * clock associations.  A set of utility routines is included to open
 * serial devices, process sample data, edit input lines to extract
 * embedded timestamps and to perform various debugging functions.
 *
 * The main interface used by these routines is the refclockproc
 * structure, which contains for most drivers the decimal equivalants
 * of the year, day, month, hour, second and millisecond/microsecond
 * decoded from the ASCII timecode.  Additional information includes
 * the receive timestamp, exception report, statistics tallies, etc. 
 * In addition, there may be a driver-specific unit structure used for
 * local control of the device.
 *
 * The support routines are passed a pointer to the peer structure,
 * which is used for all peer-specific processing and contains a
 * pointer to the refclockproc structure, which in turn contains a
 * pointer to the unit structure, if used.  The peer structure is

/*
 * This code keeps a simple address-and-mask list of hosts we want
 * to place restrictions on (or remove them from). The restrictions
 * are implemented as a set of flags which tell you what the host
 * can't do. There is a subroutine entry to return the flags. The
 * list is kept sorted to reduce the average number of comparisons
 * and make sure you get the set of restrictions most specific to
 * the address.
 *
 * The algorithm is that, when looking up a host, it is first assumed
 * that the default set of restrictions will apply. It then searches
 * down through the list. Whenever it finds a match it adopts the
 * match's flags instead. When you hit the point where the sorted
 * address is greater than the target, you return with the last set of
 * flags you found. Because of the ordering of the list, the most
 * specific match will provide the final set of flags.
 *
 * This was originally intended to restrict you from sync'ing to your
 * own broadcasts when you are doing that, by restricting yourself from
 * your own interfaces. It was also thought it would sometimes be useful
 * to keep a misbehaving host or two from abusing your primary clock. It
 * has been expanded, however, to suit the needs of those with more
 * restrictive access policies.

/* This should support the use of an EES M201 receiver with RS232

 *
 * For the format of the message sent by the clock, see the EESM_
 * definitions below.
 *
 * It appears to run free for an integral number of minutes, until the error
 * reaches 4mS, at which point it steps at second = 01.
 * It appears that sometimes it steps 4mS (say at 7 min interval),
 * then the next minute it decides that it was an error, so steps back.
 * On the next minute it steps forward again :-(
 * This is typically 16.5uS/S then 3975uS at the 4min re-sync,
 * or 9.5uS/S then 3990.5uS at a 7min re-sync,
 * at which point it may lose the "00" second time stamp.
 * I assume that the most accurate time is just AFTER the re-sync.
 * Hence remember the last cycle interval,
 *
 * Can run in any one of:
 *
 *	PPSCD	PPS signal sets CD which interupts, and grabs the current TOD
 *	(sun)		*in the interupt code*, so as to avoid problems with
 *			the STREAMS scheduling.
 *
 * It appears that it goes 16.5 uS slow each second, then every 4 mins it
 * generates no "00" second tick, and gains 3975 uS. Ho Hum ! (93/2/7)

 *
 * -------  BYTE-SWAPPING  -------
 * TSIP is big-endian (Motorola) protocol.  To use on little-endian (Intel)
 * systems, the bytes of all multi-byte types (shorts, floats, doubles, etc.)
 * must be reversed.  This is controlled by the MACRO BYTESWAP; if defined, it
 * assumes little-endian protocol.
 * --------------------------------
 *
 * T_PARSER.C and T_PARSER.H contains primitive functions that interpret
 * reports received from the receiver.  A second source file pair,
 * T_FORMAT.C and T_FORMAT.H, contin the matching TSIP command formatters.
 *
 * The module is in very portable, basic C language.  It can be used as is, or
 * with minimal changes if a TSIP communications application is needed separate
 * from TSIPCHAT. The construction of most argument lists avoid the use of
 * structures, but the developer is encouraged to reconstruct them using such
 * definitions to meet project requirements.  Declarations of T_PARSER.C
 * functions are included in T_PARSER.H to provide prototyping definitions.
 *
 * There are two types of functions: a serial input processing routine,
 *                            tsip_input_proc()
 * which assembles incoming bytes into a TSIPPKT structure, and the
 * report parsers, rpt_0x??().
 *
 * 1) The function tsip_input_proc() accumulates bytes from the receiver,
 * strips control bytes (DLE), and checks if the report end sequence (DLE ETX)
 * has been received.  rpt.status is defined as TSIP_PARSED_FULL (== 1)
 * if a complete packet is available.
 *
 * 2) The functions rpt_0x??() are report string interpreters patterned after
 * the document called "Trimble Standard Interface Protocol".  It should be
 * noted that if the report buffer is sent into the receiver with the wrong
 * length (byte count), the rpt_0x??() returns the Boolean equivalence for
 * TRUE.

 * T_REPORT.C consists of a primary function TranslateTSIPReportToText()

 *
 * This function takes a character buffer that has been received as a report

 *
 * A large case statement directs processing to one of many mid-level
 * functions.  The mid-level functions specific to the current report
 * code passes the report buffer to the appropriate report decoder
 * rpt_0x?? () in T_PARSER.C, which converts the byte stream in rpt.buf
 * to data values approporaite for use.

/*
 * Audio CHU demodulator/decoder
 *
 * This driver synchronizes the computer time using data encoded in
 * radio transmissions from Canadian time/frequency station CHU in
 * Ottawa, Ontario. Transmissions are made continuously on 3330 kHz,
 * 7850 kHz and 14670 kHz in upper sideband, compatible AM mode. An
 * ordinary shortwave receiver can be tuned manually to one of these
 * frequencies or, in the case of ICOM receivers, the receiver can be
 * tuned automatically as propagation conditions change throughout the
 * day and season.
 *
 * The driver requires an audio codec or sound card with sampling rate 8
 * kHz and mu-law companding. This is the same standard as used by the
 * telephone industry and is supported by most hardware and operating
 * systems, including Solaris, SunOS, FreeBSD, NetBSD and Linux. In this
 * implementation, only one audio driver and codec can be supported on a
 * single machine.
 *
 * The driver can be compiled to use a Bell 103 compatible modem or
 * modem chip to receive the radio signal and demodulate the data.
 * Alternatively, the driver can be compiled to use the audio codec of
 * the workstation or another with compatible audio drivers. In the
 * latter case, the driver implements the modem using DSP routines, so
 * the radio can be connected directly to either the microphone on line
 * input port. In either case, the driver decodes the data using a
 * maximum-likelihood technique which exploits the considerable degree
 * of redundancy available to maximize accuracy and minimize errors.
 *
 * The CHU time broadcast includes an audio signal compatible with the
 * Bell 103 modem standard (mark = 2225 Hz, space = 2025 Hz). The signal
 * consists of nine, ten-character bursts transmitted at 300 bps between
 * seconds 31 and 39 of each minute. Each character consists of eight
 * data bits plus one start bit and two stop bits to encode two hex
 * digits. The burst data consist of five characters (ten hex digits)
 * followed by a repeat of these characters. In format A, the characters
 * are repeated in the same polarity; in format B, the characters are
 * repeated in the opposite polarity.
 *
 * Format A bursts are sent at seconds 32 through 39 of the minute in
 * hex digits (nibble swapped)
 *
 *	6dddhhmmss6dddhhmmss
 *
 * The first ten digits encode a frame marker (6) followed by the day
 * (ddd), hour (hh in UTC), minute (mm) and the second (ss). Since
 * format A bursts are sent during the third decade of seconds the tens
 * digit of ss is always 3. The driver uses this to determine correct
 * burst synchronization. These digits are then repeated with the same
 * polarity.
 *
 * Format B bursts are sent at second 31 of the minute in hex digits
 *
 *	xdyyyyttaaxdyyyyttaa
 *
 * The first ten digits encode a code (x described below) followed by
 * the DUT1 (d in deciseconds), Gregorian year (yyyy), difference TAI -
 * UTC (tt) and daylight time indicator (aa) peculiar to Canada. These
 * digits are then repeated with inverted polarity.
 *
 * The x is coded
 *
 * 1 Sign of DUT (0 = +)
 * 2 Leap second warning. One second will be added.
 * 4 Leap second warning. One second will be subtracted.
 * 8 Even parity bit for this nibble.
 *
 * By design, the last stop bit of the last character in the burst
 * coincides with 0.5 second. Since characters have 11 bits and are
 * transmitted at 300 bps, the last stop bit of the first character
 * coincides with 0.5 - 9 * 11/300 = 0.170 second. Depending on the
 * UART, character interrupts can vary somewhere between the end of bit
 * 9 and end of bit 11. These eccentricities can be corrected along with
 * the radio propagation delay using fudge time 1.
 *
 * Debugging aids
 *
 * The timecode format used for debugging and data recording includes
 * data helpful in diagnosing problems with the radio signal and serial
 * connections. With debugging enabled (-d on the ntpd command line),
 * the driver produces one line for each burst in two formats
 * corresponding to format A and B.Each line begins with the format code
 * chuA or chuB followed by the status code and signal level (0-9999).
 * The remainder of the line is as follows.
 *
 * Following is format A:
 *
 *	n b f s m code
 *
 * where n is the number of characters in the burst (0-10), b the burst
 * distance (0-40), f the field alignment (-1, 0, 1), s the
 * synchronization distance (0-16), m the burst number (2-9) and code
 * the burst characters as received. Note that the hex digits in each
 * character are reversed, so the burst
 *
 *	10 38 0 16 9 06851292930685129293
 *
 * is interpreted as containing 10 characters with burst distance 38,
 * field alignment 0, synchronization distance 16 and burst number 9.
 * The nibble-swapped timecode shows day 58, hour 21, minute 29 and
 * second 39.
 *
 * Following is format B:
 * 
 *	n b s code
 *
 * where n is the number of characters in the burst (0-10), b the burst
 * distance (0-40), s the synchronization distance (0-40) and code the
 * burst characters as received. Note that the hex digits in each
 * character are reversed and the last ten digits inverted, so the burst
 *
 *	10 40 1091891300ef6e76ec
 *
 * is interpreted as containing 10 characters with burst distance 40.
 * The nibble-swapped timecode shows DUT1 +0.1 second, year 1998 and TAI
 * - UTC 31 seconds.
 *
 * Each line is preceeded by the code chuA or chuB, as appropriate. If
 * the audio driver is compiled, the current gain (0-255) and relative
 * signal level (0-9999) follow the code. The receiver volume control
 * should be set so that the gain is somewhere near the middle of the
 * range 0-255, which results in a signal level near 1000.
 *
 * In addition to the above, the reference timecode is updated and
 * written to the clockstats file and debug score after the last burst
 * received in the minute. The format is
 *
 *	sq yyyy ddd hh:mm:ss l s dd t agc ident m b      
 *
 * s	'?' before first synchronized and ' ' after that
 * q	status code (see below)
 * yyyy	year
 * ddd	day of year
 * hh:mm:ss time of day
 * l	leap second indicator (space, L or D)
 * dst	Canadian daylight code (opaque)
 * t	number of minutes since last synchronized
 * agc	audio gain (0 - 255)
 * ident identifier (CHU0 3330 kHz, CHU1 7850 kHz, CHU2 14670 kHz)
 * m	signal metric (0 - 100)
 * b	number of timecodes for the previous minute (0 - 59)
 *
 * Fudge factors
 *
 * For accuracies better than the low millisceconds, fudge time1 can be
 * set to the radio propagation delay from CHU to the receiver. This can
 * be done conviently using the minimuf program.
 *
 * Fudge flag4 causes the dubugging output described above to be
 * recorded in the clockstats file. When the audio driver is compiled,
 * fudge flag2 selects the audio input port, where 0 is the mike port
 * (default) and 1 is the line-in port. It does not seem useful to
 * select the compact disc player port. Fudge flag3 enables audio
 * monitoring of the input signal. For this purpose, the monitor gain is
 * set to a default value.
 *
 * The audio codec code is normally compiled in the driver if the
 * architecture supports it (HAVE_AUDIO defined), but is used only if
 * the link /dev/chu_audio is defined and valid. The serial port code is
 * always compiled in the driver, but is used only if the autdio codec
 * is not available and the link /dev/chu%d is defined and valid.
 *
 * The ICOM code is normally compiled in the driver if selected (ICOM
 * defined), but is used only if the link /dev/icom%d is defined and
 * valid and the mode keyword on the server configuration command
 * specifies a nonzero mode (ICOM ID select code). The C-IV speed is
 * 9600 bps if the high order 0x80 bit of the mode is zero and 1200 bps
 * if one. The C-IV trace is turned on if the debug level is greater
 * than one.
 *
 * Alarm codes
 *
 * CEVNT_BADTIME	invalid date or time
 * CEVNT_PROP		propagation failure - no stations heard

 * This driver supports the US (NIST, USNO) and European (PTB, NPL,
 * etc.) modem time services, as well as Spectracom GPS and WWVB
 * receivers connected via a modem. The driver periodically dials a
 * number from a telephone list, receives the timecode data and
 * calculates the local clock correction. It is designed primarily for
 * use as backup when neither a radio clock nor connectivity to Internet
 * time servers is available.
 *
 * This driver requires a modem with a Hayes-compatible command set and
 * control over the modem data terminal ready (DTR) control line. The
 * modem setup string is hard-coded in the driver and may require
 * changes for nonstandard modems or special circumstances. For reasons
 * unrelated to this driver, the data set ready (DSR) control line
 * should not be set when this driver is first started.
 *
 * The calling program is initiated by setting fudge flag1, either
 * manually or automatically. When flag1 is set, the calling program
 * dials the first number in the phone command of the configuration
 * file. If that call fails, the calling program dials the second number
 * and so on. The number is specified by the Hayes ATDT prefix followed
 * by the number itself, including the prefix and long-distance digits
 * and delay code, if necessary. The flag1 is reset and the calling
 * program terminated if (a) a valid clock update has been determined,
 * (b) no more numbers remain in the list, (c) a device fault or timeout
 * occurs or (d) fudge flag1 is reset manually.
 *
 * The driver is transparent to each of the modem time services and
 * Spectracom radios. It selects the parsing algorithm depending on the
 * message length. There is some hazard should the message be corrupted.
 * However, the data format is checked carefully and only if all checks
 * succeed is the message accepted. Corrupted lines are discarded
 * without complaint.
 *
 * Fudge controls
 *
 * flag1	force a call in manual mode
 * flag2	enable port locking (not verified)
 * flag3	no modem; port is directly connected to device
 * flag4	not used
 *
 * time1	offset adjustment (s)
 *
 * Ordinarily, the serial port is connected to a modem; however, it can
 * be connected directly to a device or another computer for testing and
 * calibration. In this case set fudge flag3 and the driver will send a
 * single character 'T' at each poll event. In principle, fudge flag2
 * enables port locking, allowing the modem to be shared when not in use
 * by this driver. At least on Solaris with the current NTP I/O
 * routines, this results only in lots of ugly error messages.

#
# depsver.mf	included in Makefile.am for directories with .deps
#
# When building in the same directory with sources that change over
# time, such as when tracking using bk, the .deps files can become
# stale with respect to moved, deleted, or superceded headers.  Most
# commonly, this would exhibit as make reporting a failure to make a
# header file which is no longer in the location given.  To address
# this issue, we use a deps-ver file which is updated with each change
# that breaks old .deps files.  A copy of deps-ver is made into
# $(DEPDIR) if not already present.  If $(DEPDIR)/deps-ver is present
# with different contents than deps-ver, we make clean to ensure all
# .o files built before the incompatible change are rebuilt along with
# their updated .deps files, then remove $(DEPDIR) and recreate it as
# empty stubs.
#
# It is normal when configured with --disable-dependency-tracking for
# the DEPDIR to not have been created.  For this reason, we use the
# intermediate target .deps-ver, which invokes make recursively if
# DEPDIR exists.
#
# If you modify depsver.mf, please make the changes to the master
# copy, the one in sntp is copied by the bootstrap script from it.
#
# This comment block follows rather than leads the related code so that
# it stays with it in the generated Makefile.in and Makefile.
#

# Tell versions [3.59,3.63) of GNU make to not export all variables.
# Otherwise a system limit (for SysV at least) may be exceeded.

/*
 * This driver supports the Austron 2200A/2201A GPS Receiver with
 * Buffered RS-232-C Interface Module. Note that the original 2200/2201
 * receivers will not work reliably with this driver, since the older
 * design cannot accept input commands at any reasonable data rate.
 *
 * The program sends a "*toc\r" to the radio and expects a response of
 * the form "yy:ddd:hh:mm:ss.mmm\r" where yy = year of century, ddd =
 * day of year, hh:mm:ss = second of day and mmm = millisecond of
 * second. Then, it sends statistics commands to the radio and expects
 * a multi-line reply showing the corresponding statistics or other
 * selected data. Statistics commands are sent in order as determined by
 * a vector of commands; these might have to be changed with different
 * radio options. If flag4 of the fudge configuration command is set to
 * 1, the statistics data are written to the clockstats file for later
 * processing.
 *
 * In order for this code to work, the radio must be placed in non-
 * interactive mode using the "off" command and with a single 
 * response using the "term cr" command. The setting of the "echo"
 * and "df" commands does not matter. The radio should select UTC
 * timescale using the "ts utc" command.
 *
 * There are two modes of operation for this driver. The first with
 * default configuration is used with stock kernels and serial-line
 * drivers and works with almost any machine. In this mode the driver
 * assumes the radio captures a timestamp upon receipt of the "*" that
 * begins the driver query. Accuracies in this mode are in the order of
 * a millisecond or two and the receiver can be connected to only one
 * host.
 *
 * The second mode of operation can be used for SunOS kernels that have
 * been modified with the ppsclock streams module included in this
 * distribution. The mode is enabled if flag3 of the fudge configuration
 * command has been set to 1. In this mode a precise timestamp is
 * available using a gadget box and 1-pps signal from the receiver. This
 * improves the accuracy to the order of a few tens of microseconds. In
 * addition, the serial output and 1-pps signal can be bussed to more
 * than one hosts, but only one of them should be connected to the
 * radio input data line.

.BR \-g ", " \--panicgate
Allow the first adjustment to be Big.
This option may appear an unlimited number of times.
.sp
Normally,
ntpd
exits with a message to the system log if the offset exceeds the panic threshold, which is 1000 s by default. This option allows the time to be set to any value without restriction; however, this can happen only once. If the threshold is exceeded after that,
ntpd
will exit with a message to the system log. This option can be used with the
-q
and
-x
options.
See the
tinker
configuration file directive for other options.
.TP
.BR \-i " \fIstring\fP, " \--jaildir "=" \fIstring\fP

logfile logfile
configuration file directive.
.TP
.BR \-L ", " \--novirtualips
Do not listen to virtual interfaces.
.sp
Do not listen to virtual interfaces, defined as those with
names containing a colon.  This option is deprecated.  Please
consider using the configuration file interface command, which
is more versatile.
.TP
.BR \-M ", " \--modifymmtimer
Modify Multimedia Timer (Windows only).
.sp
Set the Windows Multimedia Timer to highest resolution.  This
ensures the resolution does not change while ntpd is running,
avoiding timekeeping glitches associated with changes.

path to the PID file.
.sp
Specify the name and path of the file used to record
ntpd's
process ID.
This is the same operation as the
pidfile pidfile
configuration file directive.
.TP
.BR \-P " \fInumber\fP, " \--priority "=" \fInumber\fP
Process priority.
This option takes an integer number as its argument.
.sp
To the extent permitted by the operating system, run
ntpd
at the specified
sched_setscheduler(SCHED_FIFO)
priority.
.TP
.BR \-q ", " \--quit
Set the time and quit.
.sp
ntpd
will exit just after the first time the clock is set. This behavior mimics that of the
ntpdate
program, which is to be retired.
The
-g
and
-x
options can be used with this option.
Note: The kernel time discipline is disabled with this option.
.TP
.BR \-r " \fIstring\fP, " \--propagationdelay "=" \fIstring\fP
Broadcast/propagation delay.
.sp
Specify the default propagation delay from the broadcast/multicast server to this client. This is necessary only if the delay cannot be computed automatically by the protocol.
.TP
.BR \--saveconfigquit "=\fIstring\fP"
Save parsed configuration and quit.
.sp
Cause ntpd to parse its startup configuration file and save an
equivalent to the given filename and exit.  This option was
designed for automated testing.
.TP
.BR \-s " \fIstring\fP, " \--statsdir "=" \fIstring\fP
Statistics file location.
.sp
Specify the directory path for files created by the statistics facility.
This is the same operation as the
statsdir statsdir
configuration file directive.
.TP
.BR \-t " \fItkey\fP, " \--trustedkey "=" \fItkey\fP
Trusted key number.
This option may appear an unlimited number of times.
.sp
Add a key number to the trusted key list.
.TP
.BR \-u " \fIstring\fP, " \--user "=" \fIstring\fP
Run as userid (or userid:groupid).
.sp
Specify a user, and optionally a group, to switch to.
This option is only available if the OS supports adjusting the clock
without full root privileges.
This option is supported under NetBSD (configure with
--enable-clockctl
) and Linux (configure with
--enable-linuxcaps
).
.TP
.BR \-U " \fInumber\fP, " \--updateinterval "=" \fInumber\fP
interval in seconds between scans for new or dropped interfaces.
This option takes an integer number as its argument.
.sp
Give the time in seconds between two scans for new or dropped interfaces.
For systems with routing socket support the scans will be performed shortly after the interface change
has been detected by the system.
Use 0 to disable scanning. 60 seconds is the minimum time between scans.
.TP
.BR \--var "=\fInvar\fP"
make ARG an ntp variable (RW).
This option may appear an unlimited number of times.
.sp

.TP
.BR \--dvar "=\fIndvar\fP"
make ARG an ntp variable (RW|DEF).
This option may appear an unlimited number of times.
.sp

.TP
.BR \-x ", " \--slew
Slew up to 600 seconds.
.sp
Normally, the time is slewed if the offset is less than the step threshold, which is 128 ms by default, and stepped if above the threshold.
This option sets the threshold to 600 s, which is well within the accuracy window to set the clock manually.
Note: Since the slew rate of typical Unix kernels is limited to 0.5 ms/s, each second of adjustment requires an amortization interval of 2000 s.
Thus, an adjustment as much as 600 s will take almost 14 days to complete.
This option can be used with the
-g
and
-q
options.
See the
tinker
configuration file directive for other options.
Note: The kernel time discipline is disabled with this option.
.TP
.BR \--usepcc
Use CPU cycle counter (Windows only).
.sp
Attempt to substitute the CPU counter for QueryPerformanceCounter.
The CPU counter and QueryPerformanceCounter are compared, and if
they have the same frequency, the CPU counter (RDTSC on x86) is
used directly, saving the overhead of a system call.
.TP
.BR \--pccfreq "=\fIstring\fP"
Force CPU cycle counter use (Windows only).
.sp
Force substitution the CPU counter for QueryPerformanceCounter.
The CPU counter (RDTSC on x86) is used unconditionally with the
given frequency (in Hz).
.TP
.BR \-? , " \--help"
Display extended usage information and exit.
.TP
.BR \-! , " \--more-help"
Extended usage information passed thru pager.
.TP
.BR \- " [{\fIv|c|n\fP}]," " \--version" "[=\fI{v|c|n}\fP]"
Output version of program and exit.  The default mode is `v', a simple
version.  The `c' mode will print copyright information and `n' will
print the full copyright notice.

/*
 * This driver supports NMEA-compatible GPS receivers
 *
 * Prototype was refclock_trak.c, Thanks a lot.
 *
 * The receiver used spits out the NMEA sentences for boat navigation.
 * And you thought it was an information superhighway.	Try a raging river
 * filled with rapids and whirlpools that rip away your data and warp time.
 *
 * If HAVE_PPSAPI is defined code to use the PPSAPI will be compiled in.
 * On startup if initialization of the PPSAPI fails, it will fall back
 * to the "normal" timestamps.
 *
 * The PPSAPI part of the driver understands fudge flag2 and flag3. If
 * flag2 is set, it will use the clear edge of the pulse. If flag3 is
 * set, kernel hardpps is enabled.
 *
 * GPS sentences other than RMC (the default) may be enabled by setting
 * the relevent bits of 'mode' in the server configuration line
 * server 127.127.20.x mode X
 * 
 * bit 0 - enables RMC (1)
 * bit 1 - enables GGA (2)
 * bit 2 - enables GLL (4)
 * bit 3 - enables ZDA (8) - Standard Time & Date
 * bit 3 - enables ZDG (8) - Accord GPS Clock's custom sentence with GPS time 
 *			     very close to standard ZDA
 * 
 * Multiple sentences may be selected except when ZDG/ZDA is selected.
 *
 * bit 4/5/6 - selects the baudrate for serial port :
 *		0 for 4800 (default) 
 *		1 for 9600 
 *		2 for 19200 
 *		3 for 38400 
 *		4 for 57600

 * This function is used to correlate a receive time stamp and a
 * reference time with a PPS edge time stamp. It applies the necessary
 * fudges (fudge1 for PPS, fudge2 for receive time) and then tries to
 * move the receive time stamp to the corresponding edge. This can
 * warp into future, if a transmission delay of more than 500ms is not
 * compensated with a corresponding fudge time2 value, because then
 * the next PPS edge is nearer than the last. (Similiar to what the
 * PPS ATOM driver does, but we deal with full time stamps here, not
 * just phase shift information.) Likewise, a negative fudge time2
 * value must be used if the reference time stamp correlates with the
 * *following* PPS pulse.
 *
 * Note that the receive time fudge value only needs to move the receive
 * stamp near a PPS edge but that close proximity is not required;
 * +/-100ms precision should be enough. But since the fudge value will
 * probably also be used to compensate the transmission delay when no PPS
 * edge can be related to the time stamp, it's best to get it as close
 * as possible.
 *
 * It should also be noted that the typical use case is matching to
 * the preceeding edge, as most units relate their sentences to the
 * current second.
 *
 * The function returns PPS_RELATE_NONE (0) if no PPS edge correlation
 * can be fixed; PPS_RELATE_EDGE (1) when a PPS edge could be fixed, but
 * the distance to the reference time stamp is too big (exceeds +/-400ms)
 * and the ATOM driver PLL cannot be used to fix the phase; and
 * PPS_RELATE_PHASE (2) when the ATOM driver PLL code can be used.
 *
 * On output, the receive time stamp is replaced with the
 * corresponding PPS edge time if a fix could be made; the PPS fudge
 * is updated to reflect the proper fudge time to apply. (This implies
 * that 'refclock_process_f()' must be used!)

/*
 * About dynamic interfaces, sockets, reception and more...
 *
 * the code solves following tasks:
 *
 *   - keep a current list of active interfaces in order
 *     to bind to to the interface address on NTP_PORT so that
 *     all wild and specific bindings for NTP_PORT are taken by ntpd
 *     to avoid other daemons messing with the time or sockets.
 *   - all interfaces keep a list of peers that are referencing 
 *     the interface in order to quickly re-assign the peers to
 *     new interface in case an interface is deleted (=> gone from system or
 *     down)
 *   - have a preconfigured socket ready with the right local address
 *     for transmission and reception
 *   - have an address list for all destination addresses used within ntpd
 *     to find the "right" preconfigured socket.
 *   - facilitate updating the internal interface list with respect to
 *     the current kernel state
 *
 * special issues:
 *
 *   - mapping of multicast addresses to the interface affected is not always
 *     one to one - especially on hosts with multiple interfaces
 *     the code here currently allocates a separate interface entry for those
 *     multicast addresses
 *     iff it is able to bind to a *new* socket with the multicast address (flags |= MCASTIF)
 *     in case of failure the multicast address is bound to an existing interface.
 *   - on some systems it is perfectly legal to assign the same address to
 *     multiple interfaces. Therefore this code does not keep a list of interfaces
 *     but a list of interfaces that represent a unique address as determined by the kernel
 *     by the procedure in findlocalinterface. Thus it is perfectly legal to see only
 *     one representative of a group of real interfaces if they share the same address.

 * 2002/07/15 cjh
 * preparing for bitkeeper reposity
 *
 * 2002/09/09 cjh
 * Revision 1.1
 * - don't assume sprintf returns an int anymore
 * - change the way the firmware version is read
 * - some customers would like to put a device called
 *   data diode to the NeoClock4X device to disable
 *   the write line. We need to now the firmware
 *   version even in this case. We made a compile time
 *   definition in this case. The code was previously
 *   only available on request.
 *
 * 2003/01/08 cjh
 * Revision 1.11
 * - changing xprinf to xnprinf to avoid buffer overflows
 * - change some logic
 * - fixed memory leaks if drivers can't initialize
 *
 * 2003/01/10 cjh
 * Revision 1.12
 * - replaced ldiv
 * - add code to support FreeBSD
 *
 * 2003/07/07 cjh
 * Revision 1.13
 * - fix reporting of clock status
 *   changes. previously a bad clock
 *   status was never reset.
 *
 * 2004/04/07 cjh
 * Revision 1.14
 * - open serial port in a way
 *   AIX and some other OS can
 *   handle much better
 *
 * 2006/01/11 cjh
 * Revision 1.15
 * - remove some unsued #ifdefs
 * - fix nsec calculation, closes #499
 *
 * 2009/12/04 cjh
 * Revision 1.16
 * - change license to ntp COPYRIGHT notice. This should allow Debian
 *   to add this refclock driver in further releases.
 * - detect R2 hardware

 *
 * Notes on 468-DC and OMEGA receiver:
 *
 * Send the clock a 'R' or 'C' and once per second a timestamp will
 * appear.  Send a 'P' to get the satellite position once (GOES only.)
 *
 * Notes on the 468-DC receiver:
 *
 * Since the old east/west satellite locations are only historical, you can't
 * set your clock propagation delay settings correctly and still use
 * automatic mode. The manual says to use a compromise when setting the
 * switches. This results in significant errors. The solution; use fudge
 * time1 and time2 to incorporate corrections. If your clock is set for
 * 50 and it should be 58 for using the west and 46 for using the east,
 * use the line
 *
 * fudge 127.127.5.0 time1 +0.008 time2 -0.004
 *
 * This corrects the 4 milliseconds advance and 8 milliseconds retard
 * needed. The software will ask the clock which satellite it sees.
 *
 * Ntp.conf parameters:
 * time1 - offset applied to samples when reading WEST satellite (default = 0)
 * time2 - offset applied to samples when reading EAST satellite (default = 0)
 * val1  - stratum to assign to this clock (default = 0)
 * val2  - refid assigned to this clock (default = "TRUE", see below)
 * flag1 - will silence the clock side of ntpd, just reading the clock
 *         without trying to write to it.  (default = 0)
 * flag2 - generate a debug file /tmp/true%d.
 * flag3 - enable ppsclock streams module
 * flag4 - use the PCL-720 (BSD/OS only)

 *
 * Thanks to the author of the PST driver, which was the starting point for
 * this one.
 *
 * This driver supports the HP 58503A Time and Frequency Reference Receiver.
 * This receiver uses HP SmartClock (TM) to implement an Enhanced GPS receiver.
 * The receiver accuracy when locked to GPS in normal operation is better
 * than 1 usec. The accuracy when operating in holdover is typically better
 * than 10 usec. per day.
 *
 * The same driver also handles the HP Z3801A which is available surplus
 * from the cell phone industry.  It's popular with hams.
 * It needs a different line setup: 19200 baud, 7 data bits, odd parity
 * That is selected by adding "mode 1" to the server line in ntp.conf
 * HP Z3801A code from Jeff Mock added by Hal Murray, Sep 2005
 *
 *
 * The receiver should be operated with factory default settings.
 * Initial driver operation: expects the receiver to be already locked
 * to GPS, configured and able to output timecode format 2 messages.
 *
 * The driver uses the poll sequence :PTIME:TCODE? to get a response from
 * the receiver. The receiver responds with a timecode string of ASCII
 * printing characters, followed by a , followed by a prompt string
 * issued by the receiver, in the following format:
 * T#yyyymmddhhmmssMFLRVccscpi > 
 *
 * The driver processes the response at the  and , so what the
 * driver sees is the prompt from the previous poll, followed by this
 * timecode. The prompt from the current poll is (usually) left unread until
 * the next poll. So (except on the very first poll) the driver sees this:
 *
 * scpi > T#yyyymmddhhmmssMFLRVcc
 *
 * The T is the on-time character, at 980 msec. before the next 1PPS edge.
 * The # is the timecode format type. We look for format 2.
 * Without any of the CLK or PPS stuff, then, the receiver buffer timestamp
 * at the  is 24 characters later, which is about 25 msec. at 9600 bps,
 * so the first approximation for fudge time1 is nominally -0.955 seconds.
 * This number probably needs adjusting for each machine / OS type, so far:
 *  -0.955000 on an HP 9000 Model 712/80 HP-UX 9.05
 *  -0.953175 on an HP 9000 Model 370    HP-UX 9.10 
 *
 * This receiver also provides a 1PPS signal, but I haven't figured out
 * how to deal with any of the CLK or PPS stuff yet. Stay tuned.
 *

/*

 ** error message regression handling
 **
 ** there are quite a few errors that can occur in rapid succession such as
 ** noisy input data or no data at all. in order to reduce the amount of
 ** syslog messages in such case, we are using a backoff algorithm. We limit
 ** the number of error messages of a certain class to 1 per time unit. if a
 ** configurable number of messages is displayed that way, we move on to the
 ** next time unit / count for that class. a count of messages that have been
 ** suppressed is held and displayed whenever a corresponding message is
 ** displayed. the time units for a message class will also be displayed.
 ** whenever an error condition clears we reset the error message state,
 ** thus we would still generate much output on pathological conditions
 ** where the system oscillates between OK and NOT OK states. coping
 ** with that condition is currently considered too complicated.

/*
 * This driver supports the Trimble SVee Six Plus GPS receiver module.
 * It should support other Trimble receivers which use the Trimble Standard
 * Interface Protocol (see below).
 *
 * The module has a serial I/O port for command/data and a 1 pulse-per-second
 * output, about 1 microsecond wide. The leading edge of the pulse is
 * coincident with the change of the GPS second. This is the same as
 * the change of the UTC second +/- ~1 microsecond. Some other clocks
 * specifically use a feature in the data message as a timing reference, but
 * the SVee Six Plus does not do this. In fact there is considerable jitter
 * on the timing of the messages, so this driver only supports the use
 * of the PPS pulse for accurate timing. Where it is determined that
 * the offset is way off, when first starting up ntpd for example,
 * the timing of the data stream is used until the offset becomes low enough
 * (|offset| < CLOCK_MAX), at which point the pps offset is used.
 *
 * It can use either option for receiving PPS information - the 'ppsclock'
 * stream pushed onto the serial data interface to timestamp the Carrier
 * Detect interrupts, where the 1PPS connects to the CD line. This only
 * works on SunOS 4.1.x currently. To select this, define PPSPPS in
 * Config.local. The other option is to use a pulse-stretcher/level-converter
 * to convert the PPS pulse into a RS232 start pulse & feed this into another
 * tty port. To use this option, define PPSCLK in Config.local. The pps input,
 * by whichever method, is handled in ntp_loopfilter.c
 *
 * The receiver uses a serial message protocol called Trimble Standard
 * Interface Protocol (it can support others but this driver only supports
 * TSIP). Messages in this protocol have the following form:
 *
 *  ...  ... 
 *
 * Any bytes within the  portion of value 10 hex () are doubled
 * on transmission and compressed back to one on reception. Otherwise
 * the values of data bytes can be anything. The serial interface is RS-422
 * asynchronous using 9600 baud, 8 data bits with odd party (**note** 9 bits
 * in total!), and 1 stop bit. The protocol supports byte, integer, single,
 * and double datatypes. Integers are two bytes, sent most significant first.
 * Singles are IEEE754 single precision floating point numbers (4 byte) sent
 * sign & exponent first. Doubles are IEEE754 double precision floating point
 * numbers (8 byte) sent sign & exponent first.
 * The receiver supports a large set of messages, only a small subset of
 * which are used here. From driver to receiver the following are used:
 *
 *  ID    Description
 *
 *  21    Request current time
 *  22    Mode Select
 *  2C    Set/Request operating parameters
 *  2F    Request UTC info
 *  35    Set/Request I/O options

 * From receiver to driver the following are recognised:
 *
 *  ID    Description
 *
 *  41    GPS Time
 *  44    Satellite selection, PDOP, mode
 *  46    Receiver health
 *  4B    Machine code/status
 *  4C    Report operating parameters (debug only)
 *  4F    UTC correction data (used to get leap second warnings)
 *  55    I/O options (debug only)
 *
 * All others are accepted but ignored.

/*
 * This driver furnishes an interface for pulse-per-second (PPS) signals
 * produced by a cesium clock, timing receiver or related equipment. It
 * can be used to remove accumulated jitter over a congested link and
 * retime a server before redistributing the time to clients. It can 
 *also be used as a holdover should all other synchronization sources
 * beconme unreachable.
 *
 * Before this driver becomes active, the local clock must be set to
 * within +-0.4 s by another means, such as a radio clock or NTP
 * itself. There are two ways to connect the PPS signal, normally at TTL
 * levels, to the computer. One is to shift to EIA levels and connect to
 * pin 8 (DCD) of a serial port. This requires a level converter and
 * may require a one-shot flipflop to lengthen the pulse. The other is
 * to connect the PPS signal directly to pin 10 (ACK) of a PC paralell
 * port. These methods are architecture dependent.
 *
 * This driver requires the Pulse-per-Second API for Unix-like Operating
 * Systems, Version 1.0, RFC-2783 (PPSAPI). Implementations are
 * available for FreeBSD, Linux, SunOS, Solaris and Tru64. However, at
 * present only the Tru64 implementation provides the full generality of
 * the API with multiple PPS drivers and multiple handles per driver. If
 * the PPSAPI is normally implemented in the /usr/include/sys/timepps.h
 * header file and kernel support specific to each operating system.
 *
 * This driver normally uses the PLL/FLL clock discipline implemented in
 * the ntpd code. Ordinarily, this is the most accurate means, as the
 * median filter in the driver interface is much larger than in the
 * kernel. However, if the systemic clock frequency error is large (tens
 * to hundreds of PPM), it's better to used the kernel support, if
 * available.
 *
 * This deriver is subject to the mitigation rules described in the
 * "mitigation rulse and the prefer peer" page. However, there is an
 * important difference. If this driver becomes the PPS driver according
 * to these rules, it is acrive only if (a) a prefer peer other than
 * this driver is among the survivors or (b) there are no survivors and
 * the minsane option of the tos command is zero. This is intended to
 * support space missions where updates from other spacecraft are
 * infrequent, but a reliable PPS signal, such as from an Ultra Stable
 * Oscillator (USO) is available.
 *
 * Fudge Factors
 *
 * The PPS timestamp is captured on the rising (assert) edge if flag2 is
 * dim (default) and on the falling (clear) edge if lit. If flag3 is dim
 * (default), the kernel PPS support is disabled; if lit it is enabled.
 * If flag4 is lit, each timesampt is copied to the clockstats file for
 * later analysis. This can be useful when constructing Allan deviation
 * plots. The time1 parameter can be used to compensate for
 * miscellaneous device driver and OS delays.

 * Audio WWV/H demodulator/decoder
 *
 * This driver synchronizes the computer time using data encoded in
 * radio transmissions from NIST time/frequency stations WWV in Boulder,
 * CO, and WWVH in Kauai, HI. Transmissions are made continuously on
 * 2.5, 5, 10 and 15 MHz from WWV and WWVH, and 20 MHz from WWV. An
 * ordinary AM shortwave receiver can be tuned manually to one of these
 * frequencies or, in the case of ICOM receivers, the receiver can be
 * tuned automatically using this program as propagation conditions
 * change throughout the weasons, both day and night.
 *
 * The driver requires an audio codec or sound card with sampling rate 8
 * kHz and mu-law companding. This is the same standard as used by the
 * telephone industry and is supported by most hardware and operating
 * systems, including Solaris, SunOS, FreeBSD, NetBSD and Linux. In this
 * implementation, only one audio driver and codec can be supported on a
 * single machine.
 *
 * The demodulation and decoding algorithms used in this driver are
 * based on those developed for the TAPR DSP93 development board and the
 * TI 320C25 digital signal processor described in: Mills, D.L. A
 * precision radio clock for WWV transmissions. Electrical Engineering
 * Report 97-8-1, University of Delaware, August 1997, 25 pp., available
 * from www.eecis.udel.edu/~mills/reports.html. The algorithms described
 * in this report have been modified somewhat to improve performance
 * under weak signal conditions and to provide an automatic station
 * identification feature.
 *
 * The ICOM code is normally compiled in the driver. It isn't used,
 * unless the mode keyword on the server configuration command specifies
 * a nonzero ICOM ID select code. The C-IV trace is turned on if the
 * debug level is greater than one.
 *
 * Fudge factors
 *
 * Fudge flag4 causes the dubugging output described above to be
 * recorded in the clockstats file. Fudge flag2 selects the audio input
 * port, where 0 is the mike port (default) and 1 is the line-in port.
 * It does not seem useful to select the compact disc player port. Fudge
 * flag3 enables audio monitoring of the input signal. For this purpose,
 * the monitor gain is set to a default value.
 *
 * CEVNT_BADTIME	invalid date or time
 * CEVNT_PROP		propagation failure - no stations heard

 * phase delay is 0.91 ms, while the receiver delay is approximately 4.7
 * ms at 1000 Hz. The fudge value -0.45 ms due to the codec and other
 * causes was determined by calibrating to a PPS signal from a GPS
 * receiver. The additional propagation delay specific to each receiver
 * location can be  programmed in the fudge time1 and time2 values for
 * WWV and WWVH, respectively.
 *
 * The resulting offsets with a 2.4-GHz P4 running FreeBSD 6.1 are
 * generally within .02 ms short-term with .02 ms jitter. The long-term
 * offsets vary up to 0.3 ms due to ionosperhic layer height variations.
 * The processor load due to the driver is 5.8 percent.

You may need to also specify a
-u
option.
This option is only available if the OS supports adjusting the clock
without full root privileges.
This option is supported under NetBSD (configure with
--enable-clockctl
) and Linux (configure with
--enable-linuxcaps
).

@node ntpd keyfile
@subsection keyfile option (-k)
@cindex ntpd-keyfile

This is the ``path to symmetric keys'' option.
Specify the name and path of the symmetric key file.
/etc/ntp.keys
is the default.
This is the same operation as the
keys keyfile
configuration file directive.

@node ntpd logfile
@subsection logfile option (-l)
@cindex ntpd-logfile

This is the ``path to the log file'' option.
Specify the name and path of the log file.

logfile logfile
configuration file directive.

@node ntpd modifymmtimer
@subsection modifymmtimer option (-M)
@cindex ntpd-modifymmtimer

This is the ``modify multimedia timer (windows only)'' option.

This option has some usage constraints.  It:
@itemize @bullet
@item
must be compiled in by defining @code{SYS_WINNT} during the compilation.
@end itemize

Set the Windows Multimedia Timer to highest resolution.  This
ensures the resolution does not change while ntpd is running,
avoiding timekeeping glitches associated with changes.

@node ntpd novirtualips
@subsection novirtualips option (-L)
@cindex ntpd-novirtualips

This is the ``do not listen to virtual interfaces'' option.
Do not listen to virtual interfaces, defined as those with
names containing a colon.  This option is deprecated.  Please
consider using the configuration file interface command, which
is more versatile.

@node ntpd panicgate
@subsection panicgate option (-g)
@cindex ntpd-panicgate

This is the ``allow the first adjustment to be big'' option.

This option has some usage constraints.  It:
@itemize @bullet
@item
may appear an unlimited number of times.
@end itemize

Normally,
ntpd
exits with a message to the system log if the offset exceeds the panic threshold, which is 1000 s by default. This option allows the time to be set to any value without restriction; however, this can happen only once. If the threshold is exceeded after that,
ntpd
will exit with a message to the system log. This option can be used with the
-q
and
-x
options.
See the
tinker
configuration file directive for other options.

@node ntpd pccfreq
@subsection pccfreq option
@cindex ntpd-pccfreq

This is the ``force cpu cycle counter use (windows only)'' option.

This option has some usage constraints.  It:
@itemize @bullet
@item
must be compiled in by defining @code{SYS_WINNT} during the compilation.
@end itemize

Force substitution the CPU counter for QueryPerformanceCounter.
The CPU counter (RDTSC on x86) is used unconditionally with the
given frequency (in Hz).

@node ntpd pidfile
@subsection pidfile option (-p)
@cindex ntpd-pidfile

This is the ``path to the pid file'' option.
Specify the name and path of the file used to record
ntpd's
process ID.
This is the same operation as the
pidfile pidfile
configuration file directive.

@node ntpd priority
@subsection priority option (-P)
@cindex ntpd-priority

This is the ``process priority'' option.
To the extent permitted by the operating system, run
ntpd
at the specified
sched_setscheduler(SCHED_FIFO)
priority.

@node ntpd propagationdelay
@subsection propagationdelay option (-r)
@cindex ntpd-propagationdelay

This is the ``broadcast/propagation delay'' option.
Specify the default propagation delay from the broadcast/multicast server to this client. This is necessary only if the delay cannot be computed automatically by the protocol.

@node ntpd quit
@subsection quit option (-q)
@cindex ntpd-quit

This is the ``set the time and quit'' option.
ntpd
will exit just after the first time the clock is set. This behavior mimics that of the
ntpdate
program, which is to be retired.
The
-g
and
-x
options can be used with this option.
Note: The kernel time discipline is disabled with this option.

@node ntpd saveconfigquit
@subsection saveconfigquit option
@cindex ntpd-saveconfigquit

This is the ``save parsed configuration and quit'' option.

This option has some usage constraints.  It:
@itemize @bullet
@item
must be compiled in by defining @code{SAVECONFIG} during the compilation.
@end itemize

Cause ntpd to parse its startup configuration file and save an
equivalent to the given filename and exit.  This option was
designed for automated testing.

@node ntpd set-debug-level
@subsection set-debug-level option (-D)
@cindex ntpd-set-debug-level

This is the ``set the output debug message level'' option.

This option has some usage constraints.  It:
@itemize @bullet
@item
may appear an unlimited number of times.
@item
must be compiled in by defining @code{DEBUG} during the compilation.
@end itemize

Set the output debugging level.  Can be supplied multiple times,
but each overrides the previous value(s).

@node ntpd slew
@subsection slew option (-x)
@cindex ntpd-slew

This is the ``slew up to 600 seconds'' option.
Normally, the time is slewed if the offset is less than the step threshold, which is 128 ms by default, and stepped if above the threshold.
This option sets the threshold to 600 s, which is well within the accuracy window to set the clock manually.
Note: Since the slew rate of typical Unix kernels is limited to 0.5 ms/s, each second of adjustment requires an amortization interval of 2000 s.
Thus, an adjustment as much as 600 s will take almost 14 days to complete.
This option can be used with the
-g
and
-q
options.
See the
tinker
configuration file directive for other options.
Note: The kernel time discipline is disabled with this option.

@node ntpd statsdir
@subsection statsdir option (-s)
@cindex ntpd-statsdir

This is the ``statistics file location'' option.
Specify the directory path for files created by the statistics facility.
This is the same operation as the
statsdir statsdir
configuration file directive.

@node ntpd trustedkey
@subsection trustedkey option (-t)
@cindex ntpd-trustedkey

This is the ``trusted key number'' option.

This option has some usage constraints.  It:
@itemize @bullet
@item
may appear an unlimited number of times.
@end itemize

Add a key number to the trusted key list.

@node ntpd updateinterval
@subsection updateinterval option (-U)
@cindex ntpd-updateinterval

This is the ``interval in seconds between scans for new or dropped interfaces'' option.
Give the time in seconds between two scans for new or dropped interfaces.
For systems with routing socket support the scans will be performed shortly after the interface change
has been detected by the system.
Use 0 to disable scanning. 60 seconds is the minimum time between scans.

@node ntpd usepcc
@subsection usepcc option
@cindex ntpd-usepcc

This is the ``use cpu cycle counter (windows only)'' option.

This option has some usage constraints.  It:
@itemize @bullet
@item
must be compiled in by defining @code{SYS_WINNT} during the compilation.
@end itemize

Attempt to substitute the CPU counter for QueryPerformanceCounter.
The CPU counter and QueryPerformanceCounter are compared, and if
they have the same frequency, the CPU counter (RDTSC on x86) is
used directly, saving the overhead of a system call.

@node ntpd user
@subsection user option (-u)
@cindex ntpd-user

This is the ``run as userid (or userid:groupid)'' option.

This option has some usage constraints.  It:
@itemize @bullet
@item
must be compiled in by defining @code{HAVE_DROPROOT} during the compilation.
@end itemize

Specify a user, and optionally a group, to switch to.
This option is only available if the OS supports adjusting the clock
without full root privileges.
This option is supported under NetBSD (configure with
--enable-clockctl
) and Linux (configure with
--enable-linuxcaps
).

@node ntpd var
@subsection var option
@cindex ntpd-var

This is the ``make arg an ntp variable (rw)'' option.

This option has some usage constraints.  It:
@itemize @bullet

/*
 * ntp.conf syntax is slightly irregular in that some tokens such as
 * hostnames do not require quoting even if they might otherwise be
 * recognized as T_ terminal tokens.  This hand-crafted lexical scanner
 * uses a "followed by" value associated with each keyword to indicate
 * normal scanning of the next token, forced scanning of the next token
 * alone as a T_String, or forced scanning of all tokens to the end of
 * the command as T_String.
 * In the past the identifiers for this functionality ended in _ARG:
 *
 * NO_ARG	->	FOLLBY_TOKEN
 * SINGLE_ARG	->	FOLLBY_STRING
 * MULTIPLE_ARG	->	FOLLBY_STRINGS_TO_EOC
 *
 * Note that some tokens use FOLLBY_TOKEN even though they sometimes
 * are followed by strings.  FOLLBY_STRING is used only when needed to
 * avoid the keyword scanner matching a token where a string is needed.
 *
 * FOLLBY_NON_ACCEPT is an overloading of this field to distinguish
 * non-accepting states (where the state number does not match a T_
 * value).

/* 
 * Define a structure to hold the FSA for the keywords.
 * The structure is actually a trie.
 *
 * To save space, a single u_int32 encodes four fields, and a fifth
 * (the token completed for terminal states) is implied by the index of
 * the rule within the scan state array, taking advantage of the fact
 * there are more scan states than the highest T_ token number.
 *
 * The lowest 8 bits hold the character the state matches on.
 * Bits 8 and 9 hold the followedby value (0 - 3).  For non-accepting
 *   states (which do not match a completed token) the followedby
 *   value 3 (FOLLBY_NONACCEPTING) denotes that fact.  For accepting
 *   states, values 0 - 2 control whether the scanner forces the
 *   following token(s) to strings.
 * Bits 10 through 20 hold the next state to check not matching
 * this state's character.

 * This driver provides support for the TOD serial port of a Zyfer GPStarplus.
 * This clock also provides PPS as well as IRIG outputs.
 * Precision is limited by the serial driver, etc.
 *
 * If I was really brave I'd hack/generalize the serial driver to deal
 * with arbitrary on-time characters.  This clock *begins* the stream with
 * `!`, the on-time character, and the string is *not* EOL-terminated.
 *
 * Configure the beast for 9600, 8N1.  While I see leap-second stuff
 * in the documentation, the published specs on the TOD format only show
 * the seconds going to '59'.  I see no leap warning in the TOD format.
 *
 * The clock sends the following message once per second:
 *
 *	!TIME,2002,017,07,59,32,2,4,1
 *	      YYYY DDD HH MM SS m T O
 *
 *	!		On-time character
 *	YYYY		Year
 *	DDD	001-366	Day of Year
 *	HH	00-23	Hour
 *	MM	00-59	Minute
 *	SS	00-59	Second (probably 00-60)
 *	m	1-5	Time Mode:
 *			1 = GPS time
 *			2 = UTC time
 *			3 = LGPS time (Local GPS)
 *			4 = LUTC time (Local UTC)
 *			5 = Manual time
 *	T	4-9	Time Figure Of Merit:
 *			4         x <= 1us
 *			5   1us < x <= 10 us
 *			6  10us < x <= 100us
 *			7 100us < x <= 1ms

 * The CRYPTO_RESP bit is set to 0 for requests, 1 for responses.
 * Requests carry the association ID of the receiver; responses carry
 * the association ID of the sender. Some messages include only the
 * operation/length and association ID words and so have length 8
 * octets. Ohers include the value structure and associated value and
 * signature fields. These messages include the timestamp, filestamp,
 * value and signature words and so have length at least 24 octets. The
 * signature and/or value fields can be empty, in which case the
 * respective length words are zero. An empty value with nonempty
 * signature is syntactically valid, but semantically questionable.
 *
 * The filestamp represents the time when a cryptographic data file such
 * as a public/private key pair is created. It follows every reference
 * depending on that file and serves as a means to obsolete earlier data
 * of the same type. The timestamp represents the time when the
 * cryptographic data of the message were last signed. Creation of a
 * cryptographic data file or signing a message can occur only when the
 * creator or signor is synchronized to an authoritative source and
 * proventicated to a trusted authority.
 *
 * Note there are several conditions required for server trust. First,
 * the public key on the server certificate must be verified, which can
 * involve a hike along the certificate trail to a trusted host. Next,
 * the server trust must be confirmed by one of several identity
 * schemes. Valid cryptographic values are signed with attached
 * timestamp and filestamp. Individual packet trust is confirmed
 * relative to these values by a message digest with keys generated by a
 * reverse-order pseudorandom hash.
 *
 * State decomposition. These flags are lit in the order given. They are
 * dim only when the association is demobilized.
 *
 * CRYPTO_FLAG_ENAB	Lit upon acceptance of a CRYPTO_ASSOC message
 * CRYPTO_FLAG_CERT	Lit when a self-digned trusted certificate is
 *			accepted.
 * CRYPTO_FLAG_VRFY	Lit when identity is confirmed.
 * CRYPTO_FLAG_PROV	Lit when the first signature is verified.
 * CRYPTO_FLAG_COOK	Lit when a valid cookie is accepted.
 * CRYPTO_FLAG_AUTO	Lit when valid autokey values are accepted.
 * CRYPTO_FLAG_SIGN	Lit when the server signed certificate is
 *			accepted.
 * CRYPTO_FLAG_LEAP	Lit when the leapsecond values are accepted.

 ***********************************************************************
 *								       *
 * The following routines implement the Schnorr (IFF) identity scheme  *
 *								       *
 ***********************************************************************
 *
 * The Schnorr (IFF) identity scheme is intended for use when
 * certificates are generated by some other trusted certificate
 * authority and the certificate cannot be used to convey public
 * parameters. There are two kinds of files: encrypted server files that
 * contain private and public values and nonencrypted client files that
 * contain only public values. New generations of server files must be
 * securely transmitted to all servers of the group; client files can be
 * distributed by any means. The scheme is self contained and
 * independent of new generations of host keys, sign keys and
 * certificates.
 *
 * The IFF values hide in a DSA cuckoo structure which uses the same
 * parameters. The values are used by an identity scheme based on DSA
 * cryptography and described in Stimson p. 285. The p is a 512-bit
 * prime, g a generator of Zp* and q a 160-bit prime that divides p - 1
 * and is a qth root of 1 mod p; that is, g^q = 1 mod p. The TA rolls a
 * private random group key b (0 < b < q) and public key v = g^b, then
 * sends (p, q, g, b) to the servers and (p, q, g, v) to the clients.
 * Alice challenges Bob to confirm identity using the protocol described
 * below.
 *
 * How it works
 *
 * The scheme goes like this. Both Alice and Bob have the public primes
 * p, q and generator g. The TA gives private key b to Bob and public
 * key v to Alice.
 *
 * Alice rolls new random challenge r (o < r < q) and sends to Bob in
 * the IFF request message. Bob rolls new random k (0 < k < q), then
 * computes y = k + b r mod q and x = g^k mod p and sends (y, hash(x))
 * to Alice in the response message. Besides making the response
 * shorter, the hash makes it effectivey impossible for an intruder to
 * solve for b by observing a number of these messages.
 * 
 * Alice receives the response and computes g^y v^r mod p. After a bit
 * of algebra, this simplifies to g^k. If the hash of this result
 * matches hash(x), Alice knows that Bob has the group key b. The signed
 * response binds this knowledge to Bob's private key and the public key
 * previously received in his certificate.
 *

 ***********************************************************************
 *
 * The Guillou-Quisquater (GQ) identity scheme is intended for use when
 * the certificate can be used to convey public parameters. The scheme
 * uses a X509v3 certificate extension field do convey the public key of
 * a private key known only to servers. There are two kinds of files:
 * encrypted server files that contain private and public values and
 * nonencrypted client files that contain only public values. New
 * generations of server files must be securely transmitted to all
 * servers of the group; client files can be distributed by any means.
 * The scheme is self contained and independent of new generations of
 * host keys and sign keys. The scheme is self contained and independent
 * of new generations of host keys and sign keys.
 *
 * The GQ parameters hide in a RSA cuckoo structure which uses the same
 * parameters. The values are used by an identity scheme based on RSA
 * cryptography and described in Stimson p. 300 (with errors). The 512-
 * bit public modulus is n = p q, where p and q are secret large primes.
 * The TA rolls private random group key b as RSA exponent. These values
 * are known to all group members.
 *
 * When rolling new certificates, a server recomputes the private and
 * public keys. The private key u is a random roll, while the public key
 * is the inverse obscured by the group key v = (u^-1)^b. These values
 * replace the private and public keys normally generated by the RSA
 * scheme. Alice challenges Bob to confirm identity using the protocol
 * described below.
 *
 * How it works
 *
 * The scheme goes like this. Both Alice and Bob have the same modulus n
 * and some random b as the group key. These values are computed and
 * distributed in advance via secret means, although only the group key
 * b is truly secret. Each has a private random private key u and public
 * key (u^-1)^b, although not necessarily the same ones. Bob and Alice
 * can regenerate the key pair from time to time without affecting
 * operations. The public key is conveyed on the certificate in an
 * extension field; the private key is never revealed.
 *
 * Alice rolls new random challenge r and sends to Bob in the GQ
 * request message. Bob rolls new random k, then computes y = k u^r mod
 * n and x = k^b mod n and sends (y, hash(x)) to Alice in the response
 * message. Besides making the response shorter, the hash makes it
 * effectivey impossible for an intruder to solve for b by observing
 * a number of these messages.
 * 
 * Alice receives the response and computes y^b v^r mod n. After a bit
 * of algebra, this simplifies to k^b. If the hash of this result
 * matches hash(x), Alice knows that Bob has the group key b. The signed
 * response binds this knowledge to Bob's private key and the public key
 * previously received in his certificate.

 * The following routines implement the Mu-Varadharajan (MV) identity  *
 * scheme                                                              *
 *								       *
 ***********************************************************************
 *
 * The Mu-Varadharajan (MV) cryptosystem was originally intended when
 * servers broadcast messages to clients, but clients never send
 * messages to servers. There is one encryption key for the server and a
 * separate decryption key for each client. It operated something like a
 * pay-per-view satellite broadcasting system where the session key is
 * encrypted by the broadcaster and the decryption keys are held in a
 * tamperproof set-top box.
 *
 * The MV parameters and private encryption key hide in a DSA cuckoo
 * structure which uses the same parameters, but generated in a
 * different way. The values are used in an encryption scheme similar to
 * El Gamal cryptography and a polynomial formed from the expansion of
 * product terms (x - x[j]), as described in Mu, Y., and V.
 * Varadharajan: Robust and Secure Broadcasting, Proc. Indocrypt 2001,
 * 223-231. The paper has significant errors and serious omissions.
 *
 * Let q be the product of n distinct primes s1[j] (j = 1...n), where
 * each s1[j] has m significant bits. Let p be a prime p = 2 * q + 1, so
 * that q and each s1[j] divide p - 1 and p has M = n * m + 1
 * significant bits. Let g be a generator of Zp; that is, gcd(g, p - 1)
 * = 1 and g^q = 1 mod p. We do modular arithmetic over Zq and then
 * project into Zp* as exponents of g. Sometimes we have to compute an
 * inverse b^-1 of random b in Zq, but for that purpose we require
 * gcd(b, q) = 1. We expect M to be in the 500-bit range and n
 * relatively small, like 30. These are the parameters of the scheme and
 * they are expensive to compute.
 *
 * We set up an instance of the scheme as follows. A set of random
 * values x[j] mod q (j = 1...n), are generated as the zeros of a
 * polynomial of order n. The product terms (x - x[j]) are expanded to
 * form coefficients a[i] mod q (i = 0...n) in powers of x. These are
 * used as exponents of the generator g mod p to generate the private
 * encryption key A. The pair (gbar, ghat) of public server keys and the
 * pairs (xbar[j], xhat[j]) (j = 1...n) of private client keys are used
 * to construct the decryption keys. The devil is in the details.
 *
 * This routine generates a private server encryption file including the
 * private encryption key E and partial decryption keys gbar and ghat.
 * It then generates public client decryption files including the public
 * keys xbar[j] and xhat[j] for each client j. The partial decryption
 * files are used to compute the inverse of E. These values are suitably
 * blinded so secrets are not revealed.
 *
 * The distinguishing characteristic of this scheme is the capability to
 * revoke keys. Included in the calculation of E, gbar and ghat is the
 * product s = prod(s1[j]) (j = 1...n) above. If the factor s1[j] is
 * subsequently removed from the product and E, gbar and ghat
 * recomputed, the jth client will no longer be able to compute E^-1 and
 * thus unable to decrypt the messageblock.
 *
 * How it works
 *
 * The scheme goes like this. Bob has the server values (p, E, q, gbar,
 * ghat) and Alice has the client values (p, xbar, xhat).
 *
 * Alice rolls new random nonce r mod p and sends to Bob in the MV
 * request message. Bob rolls random nonce k mod q, encrypts y = r E^k
 * mod p and sends (y, gbar^k, ghat^k) to Alice.
 * 
 * Alice receives the response and computes the inverse (E^k)^-1 from
 * the partial decryption keys gbar^k, ghat^k, xbar and xhat. She then
 * decrypts y and verifies it matches the original r. The signed
 * response binds this knowledge to Bob's private key and the public key
 * previously received in his certificate.

/*
 * cert_sign - sign x509 certificate equest and update value structure.
 *
 * The certificate request includes a copy of the host certificate,
 * which includes the version number, subject name and public key of the
 * host. The resulting certificate includes these values plus the
 * serial number, issuer name and valid interval of the server. The
 * valid interval extends from the current time to the same time one
 * year hence. This may extend the life of the signed certificate beyond
 * that of the signer certificate.
 *
 * It is convenient to use the NTP seconds of the current time as the
 * serial number. In the value structure the timestamp is the current
 * time and the filestamp is taken from the extension field. Note this
 * routine is called only when the client clock is synchronized to a
 * proventic source, so timestamp comparisons are valid.
 *
 * The host certificate is valid from the time it was generated for a
 * period of one year. A signed certificate is valid from the time of
 * signature for a period of one year, but only the host certificate (or
 * sign certificate if used) is actually used to encrypt and decrypt
 * signatures. The signature trail is built from the client via the
 * intermediate servers to the trusted server. Each signature on the
 * trail must be valid at the time of signature, but it could happen
 * that a signer certificate expire before the signed certificate, which
 * remains valid until its expiration. 
 *
 * Returns
 * XEVNT_OK	success
 * XEVNT_CRT	bad or missing certificate
 * XEVNT_PER	host certificate expired
 * XEVNT_PUB	bad or missing public key
 * XEVNT_VFY	certificate not verified

Hardware Platform: Sun Sparc

OS: Solaris 2.6

Compiler: gcc

Version: 2.8.1

Repairs:  9

No. of files Repaired: 13


Compilation of Patches Required: yes

Results Description:

1)	Tested suspicious code.

2)	Repaired problem code and added documentation to ntp.h.

3)	Verified ntpd works on critical Y2K dates.


Comments:

1)	Errors were found in improper use of tm_year within struct tm,
	calculations that did not support year 2000 as a leap year
	(it truly is, despite any unchanged comments remaining in 
	the NTP source), and some incorrect date calculations, while
	not traditional Y2K errors, would break in the year 2000.

2)	include/ntpd.h
    	Added some definitions and documentation about the right way
        of doing things.  Definitions used by most, if not all, of
        the Y2K repairs.

Cautions:

1)	Some of the Y2K repairs were to reference clock drivers that
	we did not have the local hardware to test.  While I believe
	the changes are sound, they really need to be tested.
	This includes:

		refclock_arc.c
		refclock_heath.c
		refclock_hpgps.c

	Also, parseutil/dcfd.c is another hardware dependent module that
	was repaired without live testing.

Non-Y2K Problems Observed:

1)	Inconsistent casts of variables containing time values may
	make expansion to 64 bit integer values in a portable manner
	difficult.

2)	libntp/caltontp.c:
        Has logic I believe will fail starting in year 2100 or so.
        Left unchanged/untested as it works well beyond basic NTP 2036 
	limit checked by check_y2k.c.
        If NTP is implemented on 64-bit machines, this should be fixed

3)	ntpd/refclock_acts.c:
	ACTS time format has changed somewhat since the code was written.
	In particular the '*' '#' character switch no longer occurs...
	only '*' is typed.

      NOTE: Author (falsely) stated Y2K is NOT a leap year when it 
      really is.

      TRUTH: ACTS will go beyond Y2K: it uses FourDigitYear % 100 values
      for year so year 2000 will revert to "00".


4)     ntpd/refclock_oncore.c
       Some very strange logic in manipulating year values:
       1122         instance->pp->year = buf[6]*256+buf[7];
       Multiply by 256????
 
    Response from PHK:
       The entire protocol is binary, the year is a 16 bit quantity 
       which according to the manual can have the range 1998-2018.

Description

		
The ntpd program is an operating system daemon that synchronises the system clock with remote NTP time servers or local reference clocks. It is a complete implementation of the Network Time Protocol (NTP) version 4, but also retains compatibility with version 3, as defined by RFC-1305, and version 1 and 2, as defined by RFC-1059 and RFC-1119, respectively. The program can operate in any of several modes, as described on the Association Management page, and with both symmetric key and public key cryptography, as described on the Authentication Options page.

		
The ntpd program ordinarily requires a configuration file as desccribe on the Configuration Commands and Options collection above. However a client can discover remote servers and configure them automatically. This makes it possible to deploy a fleet of workstations without specifying configuration details specific to the local environment. Further details are on the Automatic Server Discovery page.

		
Once the NTP software distribution has been compiled and installed and the configuration file constructed, the next step is to verify correct operation and fix any bugs that may result. Usually, the command line that starts the daemon is included in the system startup file, so it is executed only at system boot time; however, the daemon can be stopped and restarted from root at any time. Once started, the daemon will begin sending and receiving messages, as specified in the configuration file.

		
Setting the Time and Frequency

		
The ntpd program operates by exchanging messages with one or more servers at designated intervals ranging from about one minute to about 17 minutes. When started, the program requires several exchanges while the algorithms accumulate and groom the data before setting the clock. The initial delay to set the clock can be reduced using options on the Server Options page.

		
Most compters today incorporate a time-of-year (TOY) chip to maintain the time during periods when the power is off. When the machine is booted, the chip is used to initialize the operating system time. In case there is no TOY chip or the TOY time is more than 1000 s from the server time, ntpd assumes something must be terribly wrong and exits with a panic message to the system operator. With the -g option the clock will be initially set to the server time regardless of the chip time. However, once the clock has been set, an error greater than 1000 s will cause ntpd to exit anyway.

		
Under ordinary conditions, ntpd slews the clock so that the time is effectively continuous and never runs backwards. If due to extreme network congestion an error spike exceeds the step threshold, by default 128 ms, the spike is discarded. However, if the error persists for more than the stepout threshold, by default 900 s, the system clock is stepped to the correct value. In practice the need for a step has is extremely rare and almost always the result of a hardware failure. With the -x option the step threshold is increased to 600 s. Other options are available using the tinker command on the Miscellaneous Options page.

		
The issues should be carefully considered before using these options. The maximum slew rate possible is limited to 500 parts-per-million (PPM) by the Unix kernel. As a result, the clock can take 2000 s for each second the clock is outside the acceptable range. During this interval the clock will not be consistent with any other network clock and the system cannot be used for distributed applications that require correctly synchronized network time.

		
The frequency file, usually called ntp.drift, contains the latest estimate  of clock frequency. If this file does not exist when ntpd is started, it enters a special mode designed to measure the particular frequency directly. The measurement takes 15 minutes, after which the frequency is set and ntpd resumes normal mode where the time and frequency are continuously adjusted. The frequency file is updated at intervals of an hour or more depending on the measured clock stability.

		
Operating Modes

		
The ntpd program normally operates continuously while adjusting the time and frequency, but in some cases it may not be practical to run it continuously. With the -q option ntpd operates as in continous mode, but exits just after setting the clock for the first time with the configured servers. Most applications will probably want to specify the iburst option with the server command. With this option a volley of messages is exchanged to groom the data and set the clock in about 10 s. If nothing is heard after a few minutes, the daemon times out and exits.

		
Poll Interval Control

		
NTP uses an intricate heuristic algorithm to automatically control the poll interval for maximum accuracy consistent with minimum network overhead. The algorithm measures the incidental offset and jitter to determine the best poll interval. When ntpd starts, the interval is the default minimum 64 s. Under normal conditions when the clock discipline has stabilized, the interval increases in steps to the default maximum 1024 s. In addition, should a server become unreachable after some time, the interval increases in steps to the maximum in order to reduce network overhead.

		
The default poll interval range is suitable for most conditions, but can be changed using options on the Server Options and Miscellaneous Options pages. However, when using maximum intervals much larger than the default, the residual clock frequency error must be small enough for the discipline loop to capture and correct. The capture range is 500 PPM with a 64-s interval decreasing by a factor of two for each interval doubling. At a 36-hr interval, for example, the capture range is only 0.24 PPM.

		
The huff-n'-puff Filter

		
In scenarios where a considerable amount of data are to be downloaded or uploaded over telephone modems, timekeeping quality can be seriously degraded. This occurs because the differential delays on the two directions of transmission can be quite large. In many cases the apparent time errors are so large as to exceed the step threshold and a step correction can occur during and after the data transfer.

		
The huff-n'-puff filter is designed to correct the apparent time offset in these cases. It depends on knowledge of the propagation delay when no other traffic is present, such as during other than work hours. The filter remembers the minimum delay over the most recent interval measured usually in hours. Under conditions of severe delay, the filter corrects the apparent offset using the sign of the offset and the difference between the apparent delay and minimum delay. The name of the filter reflects the negative (huff) and positive (puff) correction, which depends on the sign of the offset. The filter is activated by the tinker huffpuff command, as described in the Miscellaneous Options page.

		
Leap Second Processing

		
As provided by international agreement, an extra second is sometimes inserted
			in Coordinated Universal Time (UTC) at the end of a selected month,
			usually June or December. The National Institutes of Standards and
			Technology (NIST) provides an historic leapseconds file at time.nist.gov for
			retrieval via FTP. When this file, usually called ntp-leapseconds.list,
			is copied and installed in a directory. 
			The leapfile configuration command  specifies the path to
			this file. At startup, ntpd reads
			it  and initializes three leapsecond values: the NTP seconds
			at the next leap event, the offset of UTC relative to International
			Atomic Time (TAI) after the leap and the NTP seconds when the leapseconds
			file expires and should be retrieved again.

	
If a host does not have the leapsecond values, they can be obtained over the net using the Autokey security protocol. Ordinarily, the leapseconds file is installed on the primary servers and the values flow from them via secondary servers to the clients. When multiple servers are involved, the values with the latest expiration time are used.

		
If the latest leap is in the past, nothing further is done other than to install the TAI offset. If the leap is in the future less than 28 days, the leap warning bits are set. If in the future less than 23 hours, the kernel is armed to insert one second at the end of the current day. If the kernel is enabled, the leap is done automatically at that time; otherwise, the clock is effectively stopped for one second at the leap. Additional details are in the The NTP Timescale and Leap Seconds white paper

		
If none of the above provisions are available, dsependent servers and clients
			tally the leap warning bits of surviving servers and reference clocks.
			When a majority of the survivors show warning, a leap is programmed
			at the end of the current month. During the month and day of insertion,
			they operate as above. In this way the leap is is propagated at all
			dependent servers and clients.

	
Additional Features

		
A new experimental feature called interleaved modes can be used  in NTP
			symmetric or broadcast modes. It is designed to improve accuracy
			by avoiding kernel latency and queueing delay, as described on the NTP
			Interleaved Modes page. It is activated by the xleave option
			with the peer or broadcast configuration commands. The NTP
			protocol automatically reconfigures in normal or interleaved mode
			as required. Ordinary broadcast clients can use the same servers
			as interleaved clients at the same time. Further details are in the
			white paper NTP
			Interleaved On-Wire Protocol and the briefing Interleaved
			Synchronization Protocols for LANs and Space Data Links.

		
If ntpd, is configured with NetInfo support, it will attempt to read its configuration from the NetInfo service if the default ntp.conf file cannot be read and no file is specified by the -c option.

		
In contexts where a host name is expected, a -4 qualifier preceding the host name forces DNS resolution to the IPv4 namespace, while a -6 qualifier forces DNS resolution to the IPv6 namespace.

		
Various internal ntpd variables can be displayed and configuration options altered while the ntpd is running using the ntpq and ntpdc utility programs.

		
When ntpd starts it looks at the value of umask, and if zero ntpd will set the umask to 022.

		
Unless the -n, -d or -D option is used, ntpd changes the current working directory to the root directory, so any options or commands specifying paths need to use an absolute path or a path relative to the root.

		
Command Line Options

		

			
-4
			
Force DNS resolution of host names to the IPv4 namespace.
			
-6
			
Force DNS resolution of host names to the IPv6 namespace.
			
-a

			
Require cryptographic authentication for broadcast client, multicast client and symmetric passive associations. This is the same operation as the enable auth command and is the default.

			
-A

			
Do not require cryptographic authentication for broadcast client, multicast client and symmetric passive associations. This is the same operation as the disable auth command and almost never a good idea.

			
-b

			
Enable the client to synchronize to broadcast servers.

			
-c conffile

			
Specify the name and path of the configuration file, default /etc/ntp.conf.

			
-d

			
Specify debugging mode. This option may occur more than once, with each occurrence indicating greater detail of display.

			
-D level

			
Specify debugging level directly.

			
-f driftfile

			
Specify the name and path of the frequency file. This is the same operation as the driftfile driftfile command.

			
-g

			
Normally, ntpd exits with a message to the system log if the offset exceeds the panic threshold, which is 1000 s by default. This option allows the time to be set to any value without restriction; however, this can happen only once. If the threshold is exceeded after that, ntpd will exit with a message to the system log. This option can be used with the -q and -x options. See the tinker command for other options.

			
-i jaildir

			
Chroot the server to the directory jaildir. This option also implies that the server attempts to drop root privileges at startup (otherwise, chroot gives very little additional security), and it is only available if the OS supports to run the server without full root privileges. You may need to also specify a -u option.

			
-I [address | interface name]

			
Open the network address given, or all the addresses associated with the given interface name. This option may appear multiple times. This option also implies not opening other addresses, except wildcard and localhost. This option is deprecated. Please consider using the configuration file interface command, which is more versatile.

			
-k keyfile

			
Specify the name and path of the symmetric key file. This is the same operation as the keys keyfile  command.

			
-l logfile

			
Specify the name and path of the log file. The default is the system log file. This is the same operation as the logfile logfile command.

			
-L

			
Do not listen to virtual interfaces, defined as those with names containing a colon. This option is deprecated. Please consider using the configuration file interface command, which is more versatile.

			
-M

			
Raise scheduler precision to its maximum (1 msec) using timeBeginPeriod. (Windows only)

			
-n

			
Don't fork.

			
-N

			
To the extent permitted by the operating system, run the ntpd at the highest priority.

			
-p pidfile

			
Specify the name and path of the file used to record the ntpd process ID. This is the same operation as the pidfile pidfile command.

			
-P priority

			
To the extent permitted by the operating system, run the ntpd at the specified priority.

			
-q

			
Exit the ntpd just after the first time the clock is set. This behavior mimics that of the ntpdate program, which is to be retired. The -g and -x options can be used with this option. Note: The kernel time discipline is disabled with this option.

			
-r broadcastdelay

			
Specify the default propagation delay from the broadcast/multicast server to this client. This is necessary only if the delay cannot be computed automatically by the protocol.

			
-s statsdir

			
Specify the directory path for files created by the statistics facility. This is the same operation as the statsdir statsdir command.

			
-t key

			
Add a key number to the trusted key list. This option can occur more than once. This is the same operation as the trustedkey key command.

			
-u user[:group] 

			
Specify a user, and optionally a group, to switch to. This option is only available if the OS supports running the server without full root privileges. Currently, this option is supported under NetBSD (configure with --enable-clockctl) and Linux (configure with --enable-linuxcaps).

			
-U interface update interval

			
Number of seconds to wait between interface list scans to pick up new and delete network interface. Set to 0 to disable dynamic interface list updating. The default is to scan every 5 minutes.

			
-v variable

			
-V variable

			
Add a system variable listed by default.

			
-x

			
Normally, the time is slewed if the offset is less than the step threshold, which is 128 ms by default, and stepped if above the threshold. This option sets the threshold to 600 s, which is well within the accuracy window to set the clock manually. Note: Since the slew rate of typical Unix kernels is limited to 0.5 ms/s, each second of adjustment requires an amortization interval of 2000 s. Thus, an adjustment as much as 600 s will take almost 14 days to complete. This option can be used with the -g and -q options. See the tinker command for other options. Note: The kernel time discipline is disabled with this option.

			
--pccfreq frequency

			
Substitute processor cycle counter for QueryPerformanceCounter unconditionally
				using the given frequency (in Hz). --pccfreq can be used on systems
				which do not use the PCC to implement QueryPerformanceCounter
				and have a fixed PCC frequency. The frequency specified must
				be accurate within 0.5 percent. --usepcc is equivalent on many systems and should
				be tried first, as it does not require determining the frequency
				of the processor cycle counter. For x86-compatible processors, the PCC is
				also referred to as RDTSC, which is the assembly-language instruction to retrieve
				the current value.  (Windows only)

			
--usepcc

			
Substitute processor cycle counter for QueryPerformanceCounter if they
				appear equivalent. This option should be used only if the PCC
				frequency is fixed. Power-saving functionality on many laptops varies the
			PCC frequency. (Windows only)

	

		
The Configuration File

		
Ordinarily, ntpd reads the ntp.conf configuration file at startup in order to determine the synchronization sources and operating modes. It is also possible to specify a working, although limited, configuration entirely on the command line, obviating the need for a configuration file. This may be particularly useful when the local host is to be configured as a broadcast client, with servers determined by listening to broadcasts at run time.

		
Usually, the configuration file is installed as/etc/ntp.conf, but could be installed elsewhere (see the -c conffile command line option). The file format is similar to other Unix configuration files - comments begin with a # character and extend to the end of the line; blank lines are ignored.

		
Configuration commands consist of an initial command keyword followed by a list of option keywords separated by whitespace. Commands may not be continued over multiple lines. Options may be host names, host addresses written in numeric, dotted-quad form, integers, floating point numbers (when specifying times in seconds) and text strings. Optional arguments are delimited by [ ] in the options pages, while alternatives are separated by |. The notation [ ... ] means an optional, indefinite repetition of the last item before the [ ... ].

Exit Codes

		
A non-zero exit code indicates an error. Any error messages are logged to the system log by default.

		
The exit code is 0 only when ntpd is terminated by a signal, or when the -q option is used and ntpd successfully sets the system clock.

Description

		
NTP reference clock support maintains the fiction that the clock is actually an ordinary server in the NTP tradition, but operating at a synthetic stratum of zero. The entire suite of algorithms filter the received data and select the best sources to correct the system clock. No packets are exchanged with a reference clock; however, the transmit, receive and packet procedures are replaced with code to simulate them.

		
The driver assumes three timescales: standard time maintained by a distant laboratory such as USNO or NIST, reference time maintained by the external radio and the system time maintained by NTP. The radio synchronizes reference time via radio, satellite or modem. As the transmission means may not always be reliable, most radios continue to provide clock updates for some time after signal loss using an internal reference oscillator. In such cases the radio may or may not reveal the time since last synchronized or the estimated time error.

		
All three timescales run only in Coordinated Universal Time (UTC) and are not adjusted for local timezone or standard/daylight time. The local timezone, standard/daylight indicator and year, if provided, are ignored. However, it is important to determine whether a leap second is to be inserted in the UTC timescale in the near future so NTP can insert it in the system timescale at the appropriate epoch.

		
The interface routines in the ntp_refclock.c source file call the following driver routines via a transfer vector:

		

			
startup

			
The association has just been mobilized. The driver may allocate a private structure and open the device(s) required.

			
			
shutdown

			
The association is about to be demobilized. The driver should close all device(s) and free private structures.

			
receive

			
A timecode string is ready for retrieval using the refclock_gtlin() or refclock_gtraw() routines and provide clock updates.

			
poll

			
Called at poll timeout, by default 64 s. Ordinarily, the driver will send a poll sequence to the radio as required.

			
timer

			
Called once per second. This can be used for housekeeping functions. In the case with pulse-per-second (PPS) signals, this can be used to process the signals and provide clock updates.

		

		
The receive routine retrieves a timecode string via serial or parallel port, PPS signal or other means. It decodes the timecode in days, hours, minutes, seconds and nanoseconds and checks for errors. It provides these data along with the on-time timestamp to the refclock_process routine, which saves the computed offset in a 60-sample circular buffer. On occasion, either by timeout, sample count or call to the poll routine, the driver calls refclock_receive to process the circular buffer samples and update the system clock.

		
The best way to understand how the clock drivers work is to study one of the drivers already implemented, such as refclock_wwvb.c. The main interface is the refclockproc structure, which contains for most drivers the decoded timecode, on-time timestamp, reference timestamp, exception reports and statistics tallies, etc. The support routines are passed a pointer to the peer structure, which contains a pointer to the refclockproc structure, which in turn contains a pointer to the unit structure, if used. For legacy purposes, a table typeunit[type][unit] contains the peer structure pointer for each configured clock type and unit. This structure should not be used for new implementations.

		
Radio and modem reference clocks by convention have addresses of the form 127.127.t.u, where t is the clock type and u in the range 0-3 is used to distinguish multiple instances of clocks of the same type. Most clocks require a serial or parallel port or special bus peripheral. The particular device is normally specified by adding a soft link /dev/deviceu to the particular hardware device.

		
By convention, reference clock drivers are named in the form refclock_xxxx.c, where xxxx is a unique string. Each driver is assigned a unique type number, long-form driver name, short-form driver name and device name. The existing assignments are in the Reference Clock Drivers page and its dependencies. All drivers supported by the particular hardware and operating system are automatically detected in the autoconfigure phase and conditionally compiled.

		
Conventions, Fudge Factors and Flags

		
Most drivers support manual or automatic calibration for systematic offset bias using values encoded in the fudge configuration command. By convention, the time1 value defines the calibration offset in seconds. For those drivers that support statistics collection using the filegen utility and the clockstats file, the flag4 switch enables the utility.

		
If the calibration feature has been enabled, the flag1 switch is set and the PPS signal is actively disciplining the system time, the time1 value is automatically adjusted to maintain a residual offset of zero. Once the its value has stabilized, the value can be inserted in the configuration file and the calibration feature disabled.

		
Files Which Need to be Changed

		
When a new reference clock driver is installed, the following files need to be edited. Note that changes are also necessary to properly integrate the driver in the configuration and makefile scripts, but these are decidedly beyond the scope of this page.

		

			
./include/ntp.h

			
The reference clock type defines are used in many places. Each driver is assigned a unique type number. Unused numbers are clearly marked in the list. A unique REFCLK_xxxx identification code should be recorded in the list opposite its assigned type number.

			
./libntp/clocktypes.c

			
The ./libntp/clktype array is used by certain display functions. A unique short-form name of the driver should be entered together with its assigned identification code.

			
./ntpd/ntp_control.c

			
The clocktypes array is used for certain control message displays functions. It should be initialized with the reference clock class assigned to the driver, as per the NTP specification RFC-1305. See the ./include/ntp_control.h header file for the assigned classes.

			
./ntpd/refclock_conf.c

			
This file contains a list of external structure definitions which are conditionally defined. A new set of entries should be installed similar to those already in the table. The refclock_conf array is a set of pointers to transfer vectors in the individual drivers. The external name of the transfer vector should be initialized in correspondence with the type number.
			
		

		
Interface Routine Overview

		

			
refclock_newpeer - initialize and start a reference clock.

			
This routine allocates and initializes the interface structure which supports a reference clock in the form of an ordinary NTP peer. A driver-specific support routine completes the initialization, if used. Default peer variables which identify the clock and establish its reference ID and stratum are set here. It returns one if success and zero if the clock address is invalid or already running, insufficient resources are available or the driver declares a bum rap.

			
refclock_unpeer - shut down a clock

			
This routine is used to shut down a clock and return its resources to the system.

			
refclock_transmit - simulate the transmit procedure

			
This routine implements the NTP transmit procedure for a reference clock. This provides a mechanism to call the driver at the NTP poll interval, as well as provides a reachability mechanism to detect a broken radio or other madness.

			
refclock_process - insert a sample in the circular buffer

			
This routine saves the offset computed from the on-time timestamp and the days, hours, minutes, seconds and nanoseconds in the circular buffer. Note that no provision is included for the year, as provided by some (but not all) radio clocks. Ordinarily, the year is implicit in the Unix file system and hardware/software clock support, so this is ordinarily not a problem.

			
refclock_receive - simulate the receive and packet procedures

			
This routine simulates the NTP receive and packet procedures for a reference clock. This provides a mechanism in which the ordinary NTP filter, selection and combining algorithms can be used to suppress misbehaving radios and to mitigate between them when more than one is available for backup.

			
refclock_gtraw, refclock_gtlin - read the buffer and on-time timestamp

			
These routines return the data received from the clock and the on-time timestamp. The refclock_gtraw routine returns a batch of one or more characters returned by the Unix terminal routines in raw mode. The refclock_gtlin routine removes the parity bit and control characters and returns all the characters up to and including the line terminator. Either routine returns the number of characters delivered.

			
refclock_open - open a serial port for reference clock

			
This routine opens a serial port for I/O and sets default options. It returns the file descriptor if success and zero if failure.

			
refclock_ioctl - set serial port control functions
			
			
This routine attempts to hide the internal, system-specific details of serial ports. It can handle POSIX (termios), SYSV (termio) and BSD (sgtty) interfaces with varying degrees of success. The routine returns one if success and zero if failure.

			
refclock_ppsapi

			
This routine initializes the Pulse-per-Second interface (see below).

			
refclock_pps

			
This routine is called once per second to read the latest PPS offset and save it in the circular buffer (see below).

		

		
Pulse-per-Second Interface

		
When the Pulse-per-Second Application Interface (RFC 2783) is present, a
			compact PPS interface is available to all drivers. See the Mitigation
			Rules and the Prefer Peer page for further information. To use this interface,
			include the timeppps.h and refclock_atom.h header files
			and define the refclock_atom structure in the driver private storage.
			The timepps.h file is specific to each operating system and may not
			be available for some systems.

		
To use the interface, call refclock_ppsapi from the startup routine
			passing the device file descriptor and refclock_atom structure pointer.
			Then, call refclock_pps from the timer routine passing the association
			pointer and refclock_atom structure pointer. See the refclock_atom.c file
			for examples and calling sequences. If the PPS signal is valid, the offset
			sample will be save in the circular buffer and a bit set in the association
			flags word indicating the sample is valid and the driver an be selected as
			a PPS peer. If this bit is set when the poll routine is called, the driver
			calls the refclock_receive routine to process the samples in the
			circular buffer and update the system clock.

Introduction

		
This page describes the various rate management provisions in NTPv4. Details about the configuration commands and options are given on the Configuration Options page. Details about the cryptographic authentication schemes are given on the Authentication Options page. Details about the automatic server discovery schemes are described on the Automatic Server Discovery Schemes page. Additional information is available in the papers, reports, memoranda and briefings on the  NTP Project page.

		
Some national time metrology laboratories, including NIST and USNO, use the ntpd reference implementation in their very busy public time servers. They operate multiple servers behind load-balancing devices to support aggregate rates up to several thousand packets per second. The servers need to defend themselves against all manner of broken implementations that can clog the server and and network infrastructure. On the other hand, friendly ntpd clients need to avoid configurations that can result in unfriendly rates.

		
There are several features in ntpd designed to defend the servers, clients and network against accidental or intentional flood attack. On the other hand these features are also used to insure ntpd is a good citizen, even if configured in unfriendly ways. The ground rules are:

		
    
			
  • Send at the lowest rate consistent with the expected accuracy expectations.
    • 
			
  • Maintain strict minimum average headway and guard times, even if multiple burst options and/or the Autokey protocol are operating.
    • 
			
  • When the first packet of a burst is sent to a server, do not send further packets until the first packet has been received from the server.
    • 
			
  • Upon receiving a Kiss-o'-Death packet (see below), immediately reduce the sending rate.
    • 
		

		
Rate management involves four algorithms to manage resources: (1) poll rate control, (2) burst control, (3) average headway time and (4) guard time. These are described in following sections.

		
Poll Rate Control

		
Control of the poll interval is an intricate balance between expected acuracy and network load. The poll interval is constrained by the lower limit minpoll and upper limit maxpoll options of the server command and represented by the poll exponent in log2 s units. The limits default to 6 (64 s) and 10 (1024 s), respectively, which are appropriate for the vast majority of cases. The default limits can be changed with these options to a minimum set by the average option of the discard command (see below) to a maximum of 17 (36 h). Unless the best possible accuracy is required, the well mannered NTP client automatically increases the poll interval to the maximum when possible, whether or not the server is reachable. The current poll interval for each association is displayed by the ntpq program pe command. The global poll interval/time constant is displayed as the poll system variable by the rv command. The minimum global poll interval/time constant is displayed as the minpoll system variable by the rv command.

		
As a rule of thumb, the expected errors increase by a factor of two as the poll interval increases by a factor of four. The ntpd poll interval algorithm slowly increases the poll interval when jitter dominates the error budget, but quickly reduces the interval when wander dominates it. The algorithm uses a jiggle counter which operates over the range from -30 to +30 and is initialized at 0. If the measured offset is less than four times the measured average jitter, the counter is increased by the pollcurrent  exponent; if not, it is decreased by twice the poll exponent. If the counter reaches +30, the poll exponent is incremented by 1; if the counter reaches -30, the exponent is decremented by 1. In either case the counter is set to 0.

		
The poll interval is proportional to the time constant of the feedback loop which disciplines the system clock. The optimum time constant depends on the network time jitter and the clock oscillator frequency wander. Errors due to jitter decrease as the time constant increases, while errors due to wander decrease as the time constant decreases. The two error characteristics intersect at a point called the Allan intercept, which represents the ideal time constant. With a compromise Allan intercept of 2000 s, the optimim poll interval is about 64 s, which corresponds to a poll exponent of 6.

		
There is normally no need to change the poll limits, as the poll interval is managed automatically as a function of prevailing jitter and wander. The most common exceptions are the following.

		
    
			
  • With fast, lightly loaded LANs and modern processors, the nominal Allan intercept is about 500 s. In these cases the expected errors can be further reduced using a poll exponent of 4 (16 s). In the case of the pulse-per-second (PPS) driver, this is the recommended value.
    • 
			
  • With symmetric modes the most stable behavior results when both peers are configured in symmetric active mode with matching poll intervals of 6 (64 s).
    • 
			
  • The poll interval should not be modified for reference clocks, with the single exception the ACTS telephone modem driver. In this case the recommended minimum and maximum intervals are 12 (1.1 h) and 17 (36 h), respectively.
    • 
			

		
Burst Control

		
Occasionally it is necessary to send packets at intervals less than the poll interval. For instance, with the burst and iburst options of the server command, the poll algorithm sends a burst of several packets at 2-s intervals. The ntpd poll algorithm avoids sending needless packets if the server is not responding. The client begins a burst with a single packet. When the first packet is received from the server, the client continues with the remaining packets in the burst. If the first packet is not received within 64 s, it will be sent again for two additional retries before beginning backoff. The result is to minimize network load if the server is not responding.

		
For the iburst option the number of packets in the burst is six, which is the number normally needed to synchronize the clock; for the burst option, the number of packets in the burst is determined by the difference between the poll interval and the minimum poll interval set by the minpoll option of the server command. For instance, with a poll exponent of 6 (64 s), only a single packet is sent for every poll, while the full number of eight packets is sent at poll intervals of 9 (512 s) or more.

		
Average Headway Time

		
There are two features in ntpd to manage the interval between one packet and the next. These features make use of a set of counters: a client output counter for each association and a server input counter for each distinct client address. Each counter increments by a value called the headway when a packet is processed and decrements by one each second. The default minimum average headway in ntpd is 8 s, but this can be changed using the average option of the discard command, but not less than 3 (8 s).

		
If the iburst or burst options are present, the poll algorithm sends a burst of packets instead of a single packet at each poll opportunity. The NTPv4 specification requires that bursts contain no more than eight packets; so, starting from an output counter value of zero, the maximum counter value or ouput ceiling can be no more than eight times the minimum poll interval set by the minpoll option of the server command. However, if the burst starts with a counter value other than zero, there is a potential to exceed the ceiling. The poll algorithm avoids this by computing an additional headway time so that the next packet sent will not exceed the ceiling. Additional headway time can result from Autokey protocol operations. Designs such as this are often called leaky buckets. The current headway is displayed as the headway peer variable by the ntpq rv command.

		
The ntpd input packet routine uses a special list of entries, one for each distinct client address found. Each entry includes an IP address, input counter and interval since the last packet arrival. The entries are ordered by interval from the smallest to the largest. As each packet arrives, the IP source address is compared to the IP address in each entry in turn. If a match is found the entry is removed and inserted first on the list. If the IP source address does not match any entry, a new entry is created and inserted first, possibly discarding the last entry on the list if it is full. Observers will note this is the same algorithm used for page replacement in virtual memory systems.

		
In the virtual memory algorithm the entry of interest is the last, whereas here the entry of interest is the first. The input counter is decreased by the interval since it was last referenced, but not below zero. If the value of the counter plus the headway is greater than the input ceiling set by the average option, the packet is discarded. Otherwise, the counter is increased by the headway and the packet is processed. The result is, if the client maintains a maximum average headway not less than the input ceiling and transmits no more than eight packets in a burst, the input counter will not exceed the ceiling.

		
Guard Time

		
A review of past client abuse incidence shows the most frequent scenario is a broken client that attempts to send a number of packets at rates of one per second or more. On one occasion due to a defective client design, over 750,000 clients fell into this mode. There have been occasions where this abuse has persisted for days at a time. These scenarios are the most damaging, as they can threaten not only the victim server but the network infrastructure as well.

		
In the ntpd design the minimum headway between the last packet received and the current packet is called the guard time. If the headway is less than the guard time, the packet is discarded. The guard time defaults to 2 s, but this can be changed using the minimum option of the discard ommand.

		
The Kiss-of-Death Packet

		
Ordinarily, packets denied service are simply dropped with no further action except incrementing statistics counters. Sometimes a more proactive response is needed to cause the client to slow down. A special packet format has been created for this purpose called the kiss-o'-death (KoD) packet. KoD packets have leap indicator 3, stratum 0 and the reference identifier set to a four-byte ASCII code. At present, only one code RATE is sent by the server if the limited and kod flags are set in the restrict command and the rate limit is exceeded.

		
A client receiving a KoD packet is expected to slow down; however, no explicit mechanism is specified in the protocol to do this. In the current reference implementation, the server sets the packet poll to the greater of (a) minimum average headway and (b) client packet poll. The client sets the peer poll field to the maximum of (a) minimum average headway and (b) server packet poll. For KoD packets (only), the minimum peer poll is clamped not less than the peer poll and the headway temporarily increased.  

		
At present there is only one KoD packet with code RATE. In order to make sure the client notices the KoD, the receive and transmit timestamps are set to the transmit timestamp of the client packet and all other fields left as in the client packet. Thus, even if the client ignores the KoD, it cannot do any useful time computations. KoDs themselves are rate limited in the same way as arriving packets in order to deflect a flood attack.

The ntpq and ntpdc utility programs can be used to debug reference clocks, either on the server itself or from another machine elsewhere in the network. The server is compiled, installed and started using the configuration file described in the ntpd page and its dependencies. If the clock appears in the ntpq utility and pe command, no errors have occurred and the daemon has started, opened the devices specified and waiting for peers and radios to come up. If not, the first thing to look for are error messages on the system log. These are usually due to improper configuration, missing links or multiple instances of the daemon.

		
It normally takes a minute or so for evidence to appear that the clock is running and the driver is operating correctly. The first indication is a nonzero value in the reach column in the pe billboard. If nothing appears after a few minutes, the next step is to be sure the RS232 messages, if used, are getting to and from the clock. The most reliable way to do this is with an RS232 tester and to look for data flashes as the driver polls the clock and/or as data arrive from the clock. Our experience is that the overwhelming fraction of problems occurring during installation are due to problems such as miswired connectors or improperly configured device links at this stage.

		
If RS232 messages are getting to and from the clock, the variables of interest can be inspected using the ntpq program and various commands described on the documentation page. First, use the pe and as commands to display billboards showing the peer configuration and association IDs for all peers, including the radio clock. The assigned clock address should appear in the pe billboard and the association ID for it at the same relative line position in the as billboard.

		
Additional information is available with the rv and clockvar commands, which take as argument the association ID shown in the as billboard. The rv command with no argument shows the system variables, while the rv command with association ID argument shows the peer variables for the clock, as well as other peers of interest. The clockvar command with argument shows the peer variables specific to reference clock peers, including the clock status, device name, last received timecode (if relevant), and various event counters. In addition, a subset of the fudge parameters is included. The poll and error counters in the clockvar billboard are useful debugging aids. The poll counts the poll messages sent to the clock, while the noreply, badformat and baddate count various errors. Check the timecode to be sure it matches what the driver expects. This may require consulting the clock hardware reference manual, which is probably pretty dusty at this stage.

		
The ntpdc utility program can be used for detailed inspection of the clock driver status. The most useful are the clockstat and clkbug commands described in the document page. While these commands permit getting quite personal with the particular driver involved, their use is seldom necessary, unless an implementation bug shows up. If all else fails, turn on the debugging trace using two -d flags in the ntpd startup command line. Most drivers will dump status at every received message in this case. While the displayed trace can be intimidating, this provides the most detailed and revealing indicator of how the driver and clock are performing and where bugs might lurk.

		
Most drivers write a message to the clockstats file as each timecode or surrogate is received from the radio clock. By convention, this is the last ASCII timecode (or ASCII gloss of a binary-coded one) received from the radio clock. This file is managed by the filegen facility described in the ntpd page and requires specific commands in the configuration file. This forms a highly useful record to discover anomalies during regular operation of the clock. The scripts included in the ./scripts/stats directory can be run from a cron job to collect and summarize these data on a daily or weekly basis. The summary files have proven inspirational to detect infrequent misbehavior due to clock implementation bugs in some radios.

Synopsis

		sntp [{-h --help -?}][{ -v -V -W }][{-r -a}][-P prompt][-e minerr][-E maxerr][-c count][-d delay][address(es)]
		
Description

		
This program is a Simple Network Time Protocol (SNTP) client that can be used to query a Network Time Protocol (NTP) server and display the time offset of the system clock relative to the server clock. Run as root it can correct the system clock to this offset as well. It can be run as an interactive command or from a script by a cron job. The program implements the SNTP protocol defined in RFC-4330, which is a subset of the NTP protocol defined in RFC-1305, but does not provide the sanity checks, access controls, security functions and mitigation algorithms as in the full NTP implementation.

		
By default, sntp writes the local date and time (i.e., not UTC) to the standard output in the format

		
1996 Oct 15 20:17:25.123 + 4.567 +/- 0.089 secs,

		
where the + 4.567 +/- 0.089 secs indicates the time offset and error bound of the system clock relative to the server clock.

		
If a NTP server address is explicitly specified, the program sends a single message to the server and waits up to delay seconds for a unicast server message. Otherwise, it sends no message and waits up to delay seconds for a broadcast server message.

		
Options

		
sntp recognizes the following options:

		

			
-h, --help
			
displays usage information.
			
-v
			
writes diagnostic messages and a limited amount of tracing to standard error. The -v, -V and -W give increasing levels of detail.
			
-r
			
steps the system clock to the correct time by the Unix settimeofday system call. Requires root priviledge.
			
-a
			
slews the system clock to the correct time by the Unix adjtime system call. Requires root priviledge.
			
-e minerr
			
sets the minimum offset to minerr seconds. Measured offsets less than this are ignored. Acceptable values are from 0.001 to 1 with default 0.1 if unicast mode and 0.5 for broadcast mode.
			
-E maxerr
			
sets the maximum offset to maxerr seconds. Measured offsets greater than this are ignored. Acceptable values are from 1 to 60 with default 5.
			
-P prompt
			
sets the maximum automatic offset to maxerr seconds. Acceptable values are from 1 to 3600 or no, with default 30. If the program is being run interactively, measured offsets greater than this will prompt the user for confirmation. Specifying no will disable this and the correction will be made regardless.
			
-c count
			
sets the maximum number of NTP packets required to count. Acceptable values are from 1 to 25 in unicast mode and 5 to 25 in broadcast mode. The default is 5 in either mode.
			
-d delay
			
sets the maximum waiting time in broadcast mode to delay seconds. Acceptable values are from 1 to 3600, with default 15 in unicast mode and 300 in broadcast mode.
		

		
Return Value

		
The program returns an exit status of zero for success and non-zero otherwise.

The technical report [2], which is a revision and update of an earlier report [3], describes an engineering model for a precision clock discipline function for a generic operating system. The model is the same hybrid phase/frequecy-lock feedback loop used by ntpd, but implemented in the kernel. The code described in [2] is included in Solaris and Digital/Compaq/HP Tru64. It provides two system calls ntp_gettime() and ntp_adjtime() and can discipline the system clock with microsecond resolution. However, newer hardware and kernels with the same system calls can discipline the clock with nanosecond resolution. The new code described in [1] is in FreeBSD and is an option for Linux, SunOS and Tru64; however, of the options, only the Linux implementation, which does not include licensed code, is readily available. The software and documentation, including a simulator used to verify correct behavior, but not involving licensed code, is available from nanokernel.tar.gz.

		
The kernel model also provides support for an external precision timing source, such as described in the Pulse-per-second (PPS) Signal Interfacing page. The new system calls are used by the PPSAPI interface and in turn by the PPS Clock Discipline driver (type 22) to provide synchronization limited in principle only by the accuracy and stability of the external timing source.

Introduction

		
This page describes the automatic server discovery schemes provided in NTPv4. Details about the configuration commands and options are described on the Configuration Options page. Details about the cryptographic authentication schemes are described on the Authentication Options page. Details about the other modes not directly involved in these schemes are described on the Association Management page. Additional information is available in the papers, reports, memoranda and briefings on the NTP Project page.

		
There are three automatic server discovery schemes: broadcast/multicast, manycast and server pool described on this page. The broadcast/multicast and manycast schemes utilize the ubiquitous broadcast or one-to-many paradigm native to IPv4 and IPv6. The server pool scheme uses DNS to resolve addresses of multiple volunteer servers scattered throughout the world. All three schemes work in much the same way and might be described as grab-n'-prune. Through one means or another they grab a number of associations either directly or indirectly from the configuration file, order them from best to worst according to a defined metric, then cast off the associations with the lowest  metric until no more than the number specified by the maxclock option of the tos command remain.

		
Association Management

		
All schemes use a stratum filter to select just those servers with stratum considered useful. This can avoid large numbers of clients ganging up on a small number of low-stratum servers and avoid servers below or above specified stratum levels. By default, servers of all strata are acceptable; however, the tos command can be used to restrict the acceptable range from the floor option, inclusive, to the ceiling option, exclusive. Potential servers operating at the same stratum as the client will be avoided, unless the cohort option is present.

		
The pruning process is handled using a set of counters, one for each preemptible association. Once each poll interval the counter is increased by one. If the association survives the selection and clustering algorithms; that is, it is a candidate for synchronization, the counter is reset to zero. If not and the counter reaches a defined threshold and the number of assocations is greater than maxclock, the association becomes a candidate for pruning. The pruning algorithm assigns to each association a metric ranging from the lowest, corresponding to no possibility of synchronization, to the highest, corresponding to a very likely possibility of synchronization. Upon reaching the threshold, an association is demobilized if it has the lowest metric of all associations. Operation continues in this way until the number of remaining associations is not greater than maxclock.

		
Following is a summary of each scheme. Note that reference to option applies to the commands described on the Configuration Options page. See that page for applicability and defaults.

		
Broadcast/Multicast Scheme

		
A broadcast server generates messages continuously at intervals by default 64 s and time-to-live by default 127. These defaults can be overriden by the minpoll and ttl options, respectively. Not all kernels support the ttl option. A broadcast client responds to the first message received by waiting a randomized interval to avoid implosion at the server. It then polls the server in client/server mode using the iburst option in order to quickly authenticate the server, calibrate the propagation delay and set the host clock. This normally results in a volley of six client/server exchanges at 2-s intervals during which both the synchronization and cryptographic protocols run concurrently.

		
Following the volley, the server continues in listen-only mode and sends no further messages. If for some reason the broadcast server does not respond to these messages, the client will cease transmission and continue in listen-only mode with a default propagation delay. The volley can be avoided by using the authdelay command with nonzero argument.

		
A server is configured in broadcast mode using the broadcast command and specifying the broadcast address of a local interface. If two or more local interfaces are installed with different broadcast addresses, a broadcast command is needed for each address. This provides a way to limit exposure in a firewall, for example. A broadcast client is configured using the broadcastclient command. 

		
NTP multicast mode can be used to extend the scope using IPv4 multicast or IPv6 broadcast with defined span. The IANA has assigned IPv4 multicast address 224.0.1.1 and IPv6 address FF05::101 (site local) to NTP, but these addresses should be used only where the multicast span can be reliably constrained to protect neighbor networks. In general, administratively scoped IPv4 group addresses should be used, as described in RFC-2365, or GLOP group addresses, as described in RFC-2770.

		
A multicast server is configured using the broadcast command, but specifying a multicast address instead of a broadcast address. A multicast client is configured using the multicastclient command specifying a list of one or more multicast addresses. Note that there is a subtle distinction between the IPv4 and IPv6 address families. The IPv4 broadcast or mulitcast mode is determined by the IPv4 class. For IPv6 the same distinction can be made using the link-local prefix FF02 for each interface and site-local prefix FF05 for all interfaces.

		
It is possible and frequently useful to configure a host as both broadcast client and broadcast server. A number of hosts configured this way and sharing a common broadcast address will automatically organize themselves in an optimum configuration based on stratum and synchronization distance.

		
Since an intruder can impersonate a broadcast server and inject false time values, broadcast mode should always be cryptographically authenticated. By default, a broadcast association will not be mobilized unless cryptographically authenticated. If necessary, the auth option of the disable command will disable this feature. The feature can be selectively enabled using the notrust option of the restrict command.

		
With symmetric key cryptography each broadcast server can use the same or different keys. In one scenario on a broadcast LAN, a set of broadcast clients and servers share the same key along with another set that share a different key. Only the clients with matching key will respond to a server broadcast.

		
Public key cryptography can be used with some restrictions. If multiple servers belonging to different secure groups share the same broadcast LAN, the clients on that LAN must have the client keys for all of them. This scenario is illustrated in the example on the Authentication Options page.

		
Manycast Scheme

		
Manycast is a automatic server discovery and configuration paradigm new to NTPv4. It is intended as a means for a client to troll the nearby network neighborhood to find cooperating servers, validate them using cryptographic means and evaluate their time values with respect to other servers that might be lurking in the vicinity. It uses the grab-n'-drop paradigm with the additional feature that active means are used to grab additional servers should the number of survivors fall below the minclock option of the tos command.

		
The manycast paradigm is not the anycast paradigm described in RFC-1546, which is designed to find a single server from a clique of servers providing the same service. The manycast paradigm is designed to find a plurality of redundant servers satisfying defined optimality criteria.

		
A manycast clients is configured using the manycastclient configuration command, which is similar to the server configuration command. It sends ordinary client mode messages, but with a broadcast address rather than a unicast address and sends only if less than minclock associateons remain and then only at the minimum feasible rate and minimum feasible time-to-live (TTL) hops. The polling strategy is designed to reduce as much as possible the volume of broadcast messages and the effects of implosion due to near-simultaneous arrival of manycast server messages. There can be as many manycast client associations as different addresses, each one serving as a template for a future unicast client/server association.

		
A manycast server is configured using the manycastserver command, which listens on the specified broadcast address for manycast client messages. If a manycast server is in scope of the current TTL and is itself synchronized to a valid source and operating at a stratum level equal to or lower than the manycast client, it replies with an ordinary unicast server message.

		
The manycast client receiving this message mobilizes a preemptable client association according to the matching manycast client template, but only if cryptographically authenticated and the server stratum is less than or equal to the client stratum. 

		
It is possible and frequently useful to configure a host as both manycast client and manycast server. A number of hosts configured this way and sharing a common multicast group address will automatically organize themselves in an optimum configuration based on stratum and synchronization distance.

		
The use of cryptograpic authentication is always a good idea in any server descovery scheme. Both symmetric key and public key cryptography can be used in the same scenarios as described above for the broadast/multicast scheme.

		
Server Pool Scheme

		
The idea of targeting servers on a random basis to distribute and balance the load is not a new one; however, the NTP pool scheme puts this on steroids. At present, several hundred operators around the globe have volunteered their servers for public access. In general, NTP is a lightweight service and servers used for other purposes don't mind an additional small load. The trick is to randomize over the population and minimize the load on any one server while retaining the advantages of multiple servers using the NTP mitigation algorithms.

		
To support this service the DNS for some volunteer servers as been
			modified to collect a number of other volunteer servers and return a
			randomized list in response to a DNS query. The client receiving this list
			mobilizes some or all of them just as in the other discovery schemes and casts
			off the excess.

		
The pool scheme is configured using one or pool commands with the DNS name region.pool.ntp.org, where region is a region of the world, country of the region or state of the country or even the whole world if absent. The pool command can be used more than once; duplicate servers are detected and discarded. In principle, it is possible to use a configuration file containing a single line pool pool.ntp.org.

Introduction

		
Drivers for most radio and modem reference clocks is included by default in the NTP distribution. Individual drivers can be activated using server commands as described in the ntpd program manual page. Drivers have addresses in the form 127.127.t.u, where t is the driver type and u is a unit number in the range 0-3 to distinguish multiple instances of the same driver. Most drivers require a serial or parallel port or special bus peripheral, but some can work directly from an audio codec or sound card when availble. The particular device is specified by adding a soft link from the name used by the driver to the device name.

		
All radio clock drivers require that the radio be set for Coordinated Universal Time (UTC) only. Timezone and standard/daylight adjustments are performed by the kernel. There are difference in the various Unix and Windows port interfaces detected at configuration time, so it is important that the NTP daemon and utilities be compiled on the target system or clone.

		
When a pulse-per-second (PPS) signal is available, the  PPS Clock Discipline driver is can be used. It normally works in conjunction with the reference clock that produces the signal, but can work with another driver or remote server. When PPS kernel features are present, the driver can redirect the PPS signal to the kernel.

		
In general, performance can be improved, especially when more than one driver is supported, to use the prefer peer function described in the Mitigation Rules and the prefer Keyword page. The prefer peer is ordinarily designated the remote peer or local clock driver which provides the best quality time. All other things equal, only the prefer peer is used to discipline the system clock and jitter-producing "clockhopping" between sources is avoided. This is especially valuable when the PPS clock discipline driver is available.

		
There are audio drivers for each of the NIST time stations WWV and WWVH, Canadian time station CHU and generic IRIG signals. Currently, support for FreeBSD, Solaris and SunOS is in the distribution. It is left to the volunteer corps to confirm this works in other systems. Further information on hookup, debugging and monitoring is given in the Audio Drivers page.

		
The  Undisciplined Local Clock driver can simulate a reference clock when no external synchronization sources are available. If a server with this driver is connected directly or indirectly to the public Internet, there is some danger that it can destabilize other clients. It is not recommended that the loccal clock driver be used in this way, as the orphan mode descibed on the Association Management page provides a generic backup capability.

		
The local clock driver can also be used when  an external synchronization source such as the IEEE 1588 Precision Time Protocol or NIST Lockclock directly synchronizes the computer time. Further information is on the External Clock Discipline and the Local Clock Driver page.

		
Driver Calibration

		
Some drivers depending on longwave or shortwave radio services need to know the radio propagation time from the transmitter to the receiver. This must be calculated for each specific receiver location and requires the geographic coordinates of both the transmitter and receiver. The transmitter coordinates for various radio services are given in the Time and Frequency Standard Station Information page. Receiver coordinates can be obtained locally or from Google Earth. The actual calculations are beyond the scope of this document.

		
Depending on interface type, port speed, etc., a reference clock can have a small residual offset relative to another. To reduce the effects of jitter when switching from one driver to the another, it is useful to calibrate the drivers to a common ensemble offset. The enable calibrate configuration command described on the Miscellaneous Options page activates a special feature which automatically calculates a correction factor for each driver relative to an association designated the prefer peer.

Table of Contents





Following is a description of the configuration commands in NTPv4. There are
	two classes of commands, configuration commands that configure an association
	with a remote server, peer or reference clock, and auxilliary commands that
	specify environmental variables that control various related operations. 


The various modes described on the Association Management page
	are determined by the command keyword and the DNS name or IP address. Addresses
	are classed by type as (s) a remote server or peer (IPv4 class A, B and C),
	(b) the IP broadcast address of a local interface, (m) a multicast address (IPv4
	class D), or (r) a reference clock address (127.127.x.x). For type m addresses
	the IANA has assigned the multicast group address IPv4 224.0.1.1 and IPv6 ff05::101
	(site local) exclusively to NTP, but other nonconflicting addresses can be used. 


If the Basic Socket Interface Extensions for IPv6 (RFC-2553) is detected,
	support for the IPv6 address family is generated in addition to the default
	IPv4 address family. IPv6 addresses can be identified by the presence of colons ":" in
	the address field. IPv6 addresses can be used almost everywhere where IPv4 addresses
	can be used, with the exception of reference clock addresses, which are always
	IPv4. Note that in contexts where a host name is expected, a -4 qualifier
	preceding the host name forces DNS resolution to the IPv4 namespace, while a -6 qualifier
	forces DNS resolution to the IPv6 namespace.


Configuration Commands



	
server address [options ...]

		peer address [options ...]

		broadcast address [options ...]

		manycastclient address [options ...]

		pool address [options ...]

		unpeer [address | associd]

	
These commands specify the time server name or address to be used and the
		mode in which to operate. The address can be either a DNS name or a
		IPv4 or IPv6 address in standard notation. In general, multiple commands of
		each type can be used for different server and peer addresses or multicast
		groups.
		

			
server

			
For type s and r addresses (only), this command mobilizes a persistent
				client mode association with the specified remote server or local reference
				clock. If the preempt flag is specified, a preemptable client mode
				association is mobilized instead.

			
peer

			
For type s addresses (only), this command mobilizes a persistent symmetric-active
				mode association with the specified remote peer.

			
broadcast

			
For type b and m addressees (only), this command mobilizes a persistent
				broadcast or multicast server mode association. Note that type
				b messages go only to the interface specified, but type m messages go to
				all interfaces.

			
manycastclient

			
For type m addresses (only), this command mobilizes a manycast client
				mode association for the multicast group address specified. In this mode
				the address must match the address specified on the manycastserver command
				of one or more designated manycast servers.

			
pool

			
For type s messages (only) this command mobilizes a client mode association
				for servers implementing the pool automatic server discovery scheme described
				on the Association Management page. The address
				is a DNS name in the form area.pool.ntp.org, where area is
				a qualifier designating the server geographic area such as us or europe.

			
unpeer

			
This command removes a previously configured association. An address or association ID can
				be used to identify the association.  Either an IP address or DNS name can be used.  This
				command is most useful when supplied via ntpq runtime
				configuration commands :config and config-from-file.

		




Command Options



	
autokey

	
Send and receive packets authenticated by the Autokey scheme described
		in the Authentication Options page. This option
		is mutually exclusive with the key option.

	
burst

	
When the server is reachable, send a burst of eight packets instead of the
		usual one. The packet spacing is normally 2 s; however, the spacing between
		the first and second packets can be changed with the calldelay command
		to allow additional time for a modem or ISDN call to complete. This option
		is valid only with  the server command and type s addressesa.
		It is a recommended option when the maxpoll option is greater than
		10 (1024 s).

	
iburst

	
When the server is unreachable, send a burst of eight packets instead of
		the usual one. The packet spacing is normally 2 s; however, the spacing between
		the first and second packets can be changed with the calldelay command
		to allow additional time for a modem or ISDN call to complete. This option
		is valid only with the server command and type s addresses. It is
		a recommended option with this command.

	
key key

	
Send and receive packets authenticated by the symmetric key scheme described
		in the Authentication Options page. 
		The key specifies the key identifier with values from 1 to
		65534, inclusive. This option is mutually exclusive with the autokey option.

	
minpoll minpoll

		maxpoll maxpoll

	
These options specify the minimum and maximum poll intervals for NTP messages,
		in seconds as a power of two. The maximum poll interval defaults to 10
		(1024 s), but can be increased by the maxpoll option to an upper limit
		of 17 (36 h). The minimum poll interval defaults to 6 (64 s), but can
		be decreased by the minpoll option to a lower limit of 3 (8 s).

	
mode option

	
Pass the option to a reference clock driver, where option is
		an integer in the range from 0 to 255, inclusive. This option is valid
		only with type r addresses.

	
noselect

	
Marks the server or peer to be ignored by the selection algorithm but visible
		to the monitoring program. This option is ignored with the broadcast command.

	
preempt

	
Specifies the association as preemptable rather than the default persistent.
		This option is ignored with the broadcast command and is most useful
		with the manycastclient and pool commands.

	
prefer

	
Mark the server as preferred. All other things being equal, this host will
		be chosen for synchronization among a set of correctly operating hosts. See
		the Mitigation Rules and the prefer Keyword page
		for further information. This option is valid only with the server and peer commands.

	
true

	
Mark the association to assume truechimer status; that is, always survive
		the selection and clustering algorithms. This option can be used with any association,
		but is most useful for reference clocks with large jitter on the serial port
		and precision pulse-per-second (PPS) signals. Caution: this option defeats
		the algorithms designed to cast out falsetickers and can allow these sources
		to set the system clock. This option is valid only with the server and peer commands.

	
ttl ttl

	
This option specifies the time-to-live ttl for the broadcast command
		and the maximum ttl for the expanding ring search used by the manycastclient command.
		Selection of the proper value, which defaults to 127, is something of a black art and should be coordinated with the network administrator. This option is invalid with type r addresses.

	
version version

	
Specifies the version number to be used f
or outgoing NTP packets. Versions
		1-4 are the choices, with version 4 the default.

	
xleave

	
Operate in interleaved mode (symmetric and broadcast modes only). (see NTP
			Interleaved Modes)




Auxilliary Commands



	
broadcastclient

	
Enable reception of broadcast server messages to any local interface (type
		b address). Ordinarily, upon receiving a broadcast message for the first
		time, the broadcast client measures the nominal server propagation delay using
		a brief client/server exchange, after which it continues in listen-only mode.
		If a nonzero value is specified in the broadcastdelay command, the
		value becomes the delay and the volley is not executed. Note: the novolley option
		has been deprecated for future enhancements. Note that, in order to avoid
		accidental or malicious disruption in this mode, both the server and client
		should operate using symmetric key or public key authentication as described
		in the Authentication
		Options page. Note that the novolley keyword is incompatible with
		public key authentication.

	
manycastserver address [...]

	
Enable reception of manycast client messages (type m)to the multicast group
		address(es) (type m) specified. At least one address is required. Note that,
		in order to avoid accidental or malicious disruption, both the server and client
		should operate using symmetric key or public key authentication as described
		in the Authentication Options page.

	
multicastclient address [...]

	
Enable reception of multicast server messages to the multicast group address(es)
		(type m) specified. Upon receiving a message for the first time, the multicast
		client measures the nominal server propagation delay using a brief client/server
		exchange with the server, then enters the broadcast client mode, in which it
		synchronizes to succeeding multicast messages. Note that, in order to avoid
		accidental or malicious disruption in this mode, both the server and client
		should operate using symmetric key or public key authentication as described
		in the Authentication Options page.




Bugs


The syntax checking is not picky; some combinations of ridiculous and even
	hilarious options and modes may not be detected.

Introduction

		
Note: The NTP Version 4 software contained in this distribution is available without charge under the conditions set forth in the Copyright Notice.

		

		
It is very important that readers understand that the NTP document collection began 25 years ago and remains today a work in progress. It has evolved as new features were invented and old features retired. It has been widely copied, cached and morphed to other formats, including man pages, with varying loss of fidelity. However, these HTML pages are the ONLY authoritative and definitive reference. Readers should always use the collection that comes with the distribution they use. A copy of the online collection at www.ntp.org is normally included in the most recent snapshot, but might not agree with an earlier snapshot or release version.

		

		
The Network Time Protocol (NTP) is widely used to synchronize a computer
			to Internet time servers or other sources, such as a radio or satellite
			receiver or telephone modem service. It can also be used as a server
			for dependent clients. It provides accuracies typically less than
			a millisecond on LANs and up to a few milliseconds on WANs. Typical
			NTP configurations utilize multiple redundant servers and diverse
			network paths in order to achieve high accuracy and reliability.
			Authentication is provided  using symmetric key cryptography and
			the MD5 message digest algorithm included in the distribution. If
			the OpenSSL cryptographic library is installed, the SHA or SHA1 message
			digest algorithms can be used. If the OpenSSL library is installed,
			additional options based on public key cryptography are available.

	
NTP time synchronization services are widely available in the public Internet.
		The public NTP subnet in early 2008 includes several thousand servers
		in most countries and on every continent of the globe, including Antarctica.
		These servers support a total population estimated at over 25 million computers
		in the global Internet. The NTP subnet operates with a hierarchy of levels,
		where each level is assigned a number called the stratum. Stratum 1 (primary)
		servers at the lowest level are directly synchronized to national time services.
		Stratum 2 (secondary) servers at the next higher level are synchronize to stratum
		1 servers and so on. Normally, NTP clients and servers with a relatively small
		number of clients do not synchronize to public primary servers. There
		are several hundred public secondary servers operating at higher strata and
		are the preferred choice. 

		
Background information on computer network time synchronization is on the Executive Summary - Computer Network Time Synchronization page. Discussion on new features and interoperability with previous NTP versions is on the NTP Version 4 Release Notes page. Background information, bibliography and briefing slides suitable for presentations are on the Network Time Synchronization Research Project page. Additional information is at the NTP web site www.ntp.org.

		
Building and Installing NTP

		
NTP supports Unix, VMS and Windows (Vista, XP, NT4 and 2000) systems. The Building and Installing the Distribution page details the procedures for building and installing on a typical system. This distribution includes drivers for 44 radio and satellite receivers and telephone modem services in the US, Canada and Europe. A list of supported drivers is on the Reference Clock Drivers page. The default build includes the debugging options and all drivers that run on the target machine; however, options and drivers can be included or excluded using options on the Configuration Options page.

		
Configuring Clients and Servers

		
NTP is by its very nature a complex distributed network application and can be configured for widely divergent timekeeping scenarios. The documentation on these pages attempts to cover the entire suite of configuration, operation and maintenance features which this distribution supports. However, most applications will need only a few of these features. The Quick Start page may be useful to get a simple workstation on the air with existing servers.

		
The most important factor in providing accurate, reliable time is the selection of modes and servers in the configuration file. A discussion on the available modes is on the Association Management page. The current public server list is maintained at the www.ntp.org web site. In many cases the configuration can be automated using the schemes described on the Automatic Server Discovery Schemes page.

		
Features and Options

		
This distribution includes a statistics data recording facility which can record performance statistics and events of various types for retrospective analysis. These include time and frequency statistics, significant events and usage statistics described on the Monitoring Options page.

		
Some programs included in this distribution use cryptographic algorithms to verify server authenticity. Where local security policy permits relatively weak symmetric key cryptography, the required software is included in this distribution. Where local policy requires stronger public key cryptography, the OpenSSL library available from http://www.openssl.org is required. This library is also used by the Secure Shell facility, so is often already installed. Additional details are on the Authentication Options page.

		
This distribution includes features that can restrict access in various ways as described on the Access Control Options page. This can be used to deny service if not authenticated, deny service requiring persistent resources or deny service altogether.

		
This distribution includes a simulation framework in which substantially
			all the runtime NTP operations and most features can be tested and
			evaluated. This has been very useful in exploring in vitro response
			to unusual circumstances or over time periods impractical in vivo. Details
			are on the Network
			Time Protocol (NTP) Simulator page.

		
Resolving Problems

		
Like other things in modern Internet life, NTP problems can be devilishly intricate. This distribution includes a number of utilities designed to identify and repair problems using an integrated management protocol supported by the ntpq utility program In addition, the ntpdc utility program can be useful in some cases.

		
The NTP Debugging Techniques and Hints and Kinks pages contain useful information for identifying problems and devising solutions. Additional information on reference clock driver construction and debugging is in the Debugging Hints for Reference Clock Drivers page.

		
Users are invited to report bugs and offer suggestions via the NTP Bug Reporting Procedures page.

		
Further Information

		
The Site Map page contains a list of document collections arranged by topic. The Program Manual Pages collection may be the best place to start, followed by the Configuration Commands and Options collection. The Command Index collection contains a list of all configuration file commands together with a short function description. A great wealth of additional information is available via the External Links collection, including a book and numerous background papers and briefing presentations.

Sound Card Drivers

		
There are some applications in which the computer time can be disciplined to an audio signal, rather than a serial timecode and communications port or special purpose bus peripheral. This is useful in such cases where the audio signal is sent over a telephone circuit, for example, or received directly from a shortwave receiver. In such cases the audio signal can be connected via an ordinary sound card or baseboard audio codec. The suite of NTP reference clock drivers currently includes three drivers suitable for these applications. They include a driver for the Inter Range Instrumentation Group (IRIG) signals produced by many radio clocks and timing devices, another for the Canadian time/frequency radio station CHU and a third for the NIST time/frequency radio stations WWV and WWVH. The radio drivers are designed to work with ordinary inexpensive shortwave radios and may be one of the least expensive ways to build a good primary time server.

		
All three drivers make ample use of sophisticated digital signal processing
			algorithms designed to efficiently extract timing signals from noise and interference.
			The radio station drivers in particular implement optimum linear demodulation
			and decoding techniques, including maximum-likelihood and soft-decision methods.
			The documentation page for each driver contains an in-depth discussion on
			the algorithms and performance expectations. In some cases the algorithms
			are further analyzed, modeled and evaluated in a technical report.

		
Currently, the audio drivers work with with Sun operating systems and audio codecs, including SunOS 4.1.3 and Solaris from 2.6 and probably all others in between. They also work with FreeBSD from 4.1 with compatible sound card. In fact, the interface is quite generic and support for other systems, in particular the various Unix generics, should not be difficult. Volunteers are solicited.

		
The audio drivers include a number of common features designed to groom input signals, suppress spikes and normalize signal levels. An automatic gain control (AGC) feature provides protection against overdriven or underdriven input signals. It is designed to maintain adequate demodulator signal amplitude while avoiding occasional noise spikes. In order to assure reliable operation, the signal level must be in the range where the audio gain control is effective. In general, this means the input signal level must be such as to cause the AGC to set the gain somewhere in the middle of the range from 0 to 255, as indicated in the timecode displayed by the ntpq program.

		
The IRIG and WWV drivers operate by disciplining a logical clock based on the codec sample clock to the audio signal as received. This is done by stuffing or slipping samples as required to maintain exact frequency to the order of 0.1 PPM. In order for the driver to reliably lock on the audio signal, the sample clock frequency tolerance must be less than 250 PPM (.025 percent) for the IRIG driver and half that for the WWV driver. The largest error observed so far is about 60 PPM, but it is possible some sound cards or codecs may exceed that value. In any case, the configuration file command tinker codec command can be used to change the systematic offset in units of 125 PPM.

		
The drivers include provisions to select the input port and to monitor the input signal. The fudge flag 2 command selects the microphone port if set to zero or the line-in port if set to one. It does not seem useful to specify the compact disc player port. The fudge flag 3 command enables the input signal monitor using the previously selected output port and output gain. Both of these flags can be set in the configuration file or remotely using the ntpdc utility program.

		
Shortwave Radio Drivers

		
The WWV/H and CHU audio drivers require an external shortwave radio with the radio output - speaker or headphone jack - connected to either the microphone or line-in port on the computer. There is some degree of art in setting up the radio and antenna and getting the setup to work. While the drivers are highly sophisticated and efficient in extracting timing signals from noise and interference, it always helps to have as clear a signal as possible.

		
The most important factor affecting the radio signal is the antenna. It need not be long - even 15 feet is enough if it is located outside of a metal frame building, preferably on the roof, and away from metallic objects. An ordinary CB whip mounted on a PVC pipe and wooden X-frame on the roof should work well with most portable radios, as they are optimized for small antennas.

		
The radio need not be located near the computer; in fact, it generally works better if the radio is outside the near field of computers and other electromagnetic noisemakers. It can be in the elevator penthouse connected by house wiring, which can also be used to power the radio. A couple of center-tapped audio transformers will minimize noise pickup and provide phantom power to the radio with return via the building ground.

		
The WWV/H and CHU transmitters operate on several frequencies simultaneously, so that in most parts of North America at least one frequency supports propagation to the receiver location at any given hour. While both drivers support the ICOM CI-V radio interface and can tune the radio automatically, computer-tunable radios are expensive and probably not cost effective compared to a GPS receiver. So, the radio frequency must usually be fixed and chosen by compromise.

		
Shortwave (3-30 MHz) radio propagation phenomena are well known to shortwave enthusiasts. The phenomena generally obey the following rules:

		
    
			
  • The optimum frequency is higher in daytime than nighttime, stays high longer on summer days and low longer on winter nights.
			
  • Transitions between daytime and nighttime conditions generally occur somewhat
				after sunrise and sunset at the midpoint of the path from transmitter to
				receiver.
			
  • Ambient noise (static) on the lower frequencies follows the thunderstorm season, so is higher on summer afternoons and evenings.
			
  • The lower frequency bands are best for shorter distances, while the higher bands are best for longer distances.
			
  • The optimum frequencies are higher at the peak of the 11-year sunspot cycle and lower at the trough. The current sunspot cycle began at the minimum in late 2006 and should reach its peak in 2012.

		
The best way to choose a frequency is to listen at various times over the day and determine the highest (daytime) and lowest (nighttime) frequencies that work well. Choose the frequency that works for the most number of hours in the day, usually the highest frequency. For instance, on the east coast the best compromise CHU frequency is 7335 kHz and the best WWV frequency is 15 MHz.

		
Autotune Modes

		
The shortwave drivers include support for an optional autotune function compatible with ICOM receivers and transceivers. The mode keyword of the server configuration command specifies the ICOM ID select code in decimal. A missing or zero argument disables the CI-V interface. Since all ICOM select codes are less than 128, the high order bit of the code is used by the driver to specify the baud rate. If this bit is not set, the rate is 9600 bps for the newer radios; if set, the rate is 1200 bps for the older radios. Following are the ID select codes for the known radios.

Setup and Debugging Aids

		
The audio drivers include extensive setup and debugging support to help hook up the audio signals and monitor the driver operations. The documentation page for each driver describes the various messages that can be produced either in real time or written to the clockstats file for later analysis. Of particular help in verifying signal connections and compatibility is a provision to monitor the signal via headphones or speaker.

		
Connecting radios and IRIG devices to the computer and verifying correct
			configuration is somewhat of a black art. The signals have to be connected
			to the correct ports and the signal level maintained within tolerances. Some
			radios have recorder outputs which produce a microphone-level signal not affected
			by the volume control. These signals can be connected to the microphone port
			on the computer. If the radio does not have a recorder output, connect the
			headphone or speaker output to the line-in port and adjust the volume control
			so the driver indicates comfortably above the minimum specified and the AGC
			level somewhere in the middle of the range 0-255. IRIG signals are usually
			much larger than radio outputs, usually in the range to several volts and
			may even overload the line-in port. In such cases the signal is designed to
			drive a cable terminated with a 50-ohm resistor, which results in a level

It is very easy to underdriven or overdrive the audio codec, in which case
			the drivers will not synchronize to the signal. The drivers use fudge
			flag2 to enable audio monitoring of the input signal. This is useful
			during setup to confirm the signal is actually reaching the audio
			codec and generally free of noise and interference. Note that the monitor
			volume must be set before the driver is started.

		
The drivers write a synthesized timecode to the clockstats file each time the clock is set or verified and at other times if verbose monitoring is enabled. The format includes several fixed-length fields defining the UTC time to the millisecond, together with additional variable-length fields specific to each driver. The data include the intervals since the clock was last set or verified, the audio gain and various state variables and counters specific to each driver.

Most modern software distributions include an autoconfigure utility which
			customizes the build and install configuration according to the specific
			hardware, operating system and file system conventions. For NTP this
			utility is called configure, which is run before building and installing
			the program components. For most installations no additional actions
			are required other than running configure with no options.
			However, it is possible to customize the build and install configuration
			through the use of configure options.

		
The available options, together with
			a concise description, can be displayed by running  configure		 	with
			the --help option. Various options can be used to reduce the memory
			footprint, adjust the scheduling priority, enable or disable debugging
			support or reference clock driver support. The options can be used
			to specify where to install the program components or where to find
			various libraries if they are not in the default place.

Association Modes

		
This page describes the various modes of operation provided in NTPv4. Details about the configuration commands and options are given on the Configuration Options page. Details about the cryptographic authentication schemes are given on the Authentication Options page. Details about the automatic server discovery schemes are described on the Automatic Server Discovery Schemes page. Additional information is available in the papers, reports, memoranda and briefings on the  NTP Project page.

		
There are three types of associations in NTP: persistent, preemptable and ephemeral. Persistent associations are mobilized by a configuration command and never demobilized. Preemptable associations, which are new to NTPv4, are mobilized by a configuration command which includes the prempt option and are demobilized by a "better" server or by timeout, but only if the number of survivors exceeds the threshold set by the tos maxclock configuration command. Ephemeral associations are mobilized upon arrival of designated messages and demobilized by timeout.

		
Ordinarily, successful mobilization of ephemeral associations requires the server to be cryptographically authenticated to the client. This can be done using either symmetric key or Autokey public key cryptography, as described in the Authentication Options page.

		
There are three principal modes of operation in NTP: client/server, symmetric active/passive and broadcast/multicast. There are three automatic server discovery schemes in NTP: broadcast/multicast, manycast and pool described on the Automatic Server Discovery Schemes page. In addition, the orphan mode and burst options described on this page can be used in appropriate cases.

		
Following is a summary of the operations in each mode. Note that reference to option applies to the commands described on the Configuration Options page. See that page for applicability and defaults.

		
Client/Server Mode

		
Client/server mode is the most common configuration in the Internet today. It operates in the classic remote-procedure-call (RPC) paradigm with stateless servers and stateful clients. In this mode a host sends a client (mode 3) request to the specified server and expects a server (mode 4) reply at some future time. In some contexts this would be described as a "pull" operation, in that the host pulls the time and related values from the server.

		
A host is configured in client mode using the server (sic) command and specifying the server DNS name or IPv4 or IPv6 address; the server requires no prior configuration. The iburst option described later on this page is recommended for clients, as this speeds up initial synchronization from several minutes to several seconds. The burst option described later on this page can be useful to reduce jitter on very noisy dial-up or ISDN network links.

		
Ordinarily, the program automatically manages the poll interval between the default minimum and maximum values. The minpoll and maxpoll options can be used to bracket the range. Unless noted otherwise, these options should not be used with reference clock drivers.

		
Symmetric Active/Passive Mode

		
Symmetric active/passive mode is intended for configurations were a clique
			of low-stratum peers operate as mutual backups for each other. Each peer operates
			with one or more primary reference sources, such as a radio clock, or a set
			of secondary (stratum, 2) servers known to be reliable and authentic. Should
			one of the peers lose all reference sources or simply cease operation, the
			other peers will automatically reconfigure so that time and related values
			can flow from the surviving peers to all hosts in the subnet. In some contexts
			this would be described as a "push-pull" operation, in that the
			peer either pulls or pushes the time and related values depending on the particular
			configuration.

		
In symmetric active mode a peer symmetric active (mode 1) message to a designated peer. If a matching configured symmetric active association is found, the designated peer returns a symmetric active message. If no matching association is found, the designated peer mobilizes a ephemeral symmetric passive association and returns a symmetric passive (mode 2) message. Since an intruder can impersonate a symmetric active peer and cause a spurious symmetric passive association to be mobilized, symmetric passive mode should always be cryptographically validated.

		
A peer is configured in symmetric active mode using the peer command and specifying the other peer DNS name or IPv4 or IPv6 address. The burst and iburst options should not be used in symmetric modes, as this can upset the intended symmetry of the protocol and result in spurious duplicate or dropped messages.

		
As symmetric modes are most often used as root servers for moderate to large subnets where rapid response is required, it is generally best to set the minimum and maximum poll intervals of each root server to the same value using the minpoll and maxpoll options.

		
Broadcast/Multicast Modes

		
NTP broadcast and multicast modes are intended for configurations involving one or a few servers and a possibly very large client population. Broadcast mode can be used with Ethernet, FDDI and WiFi spans interconnected by hubs or switches. Ordinarily, broadcast packets do not extend beyond a level-3 router. Where service is intended beyond a level-3 router, multicast mode can be used. Additional information is on the Automatic NTP Configuration Options page.

		
Manycast Mode

		
Manycast mode is a automatic discovery and configuration paradigm new to NTPv4. It is intended as a means for a multicast client to troll the nearby network neighborhood to find cooperating manycast servers, validate them using cryptographic means and evaluate their time values with respect to other servers that might be lurking in the vicinity. The intended result is that each manycast client mobilizes ephemeral client associations with some number of the "best" of the nearby manycast servers, yet automatically reconfigures to sustain this number of servers should one or another fail. Additional information is on the Automatic NTP Configuration Options page.

		
Orphan Mode

		
Sometimes an NTP subnet becomes isolated from all UTC sources such as local reference clocks or Internet time servers. In such cases it may be necessary that the subnet servers and clients remain synchronized to a common timescale, not necessarily the UTC timescale. Previously, this function was provided by the local clock driver to simulate a UTC source. A server with this driver could be used to synchronize other hosts in the subnet directly or indirectly.

		
There are many disadvantages using the local clock driver, primarily that the subnet is vulnerable to single-point failures and multiple server  redundancy is not possible. Orphan mode is intended to replace the local clock driver. It provides a single simulated UTC source with multiple servers and provides seamless switching as servers fail and recover.

		
A common configuration for private networks includes one or more core servers operating at the lowest stratum. Good practice is to configure each of these servers as backup for the others using symmetric or broadcast modes. As long as at least one core server can reach a UTC source, the entire subnet can synchronize to it.

		
If no UTC sources are available to any core server, one of them can provide a simulated UTC source for all other hosts in the subnet. However, only one core server can simulate the UTC source and all direct dependents, called orphan children, must select the same one, called the orphan parent.

		
A host is enabled for orphan mode using the tos orphan stratum command, where stratum is some stratum less than 16 and greater than any anticipated stratum that might occur with configured Internet time servers. However, sufficient headroom should remain so every subnet host dependent on the orphan children has stratum less than 16. Where no associations for other servers or reference clocks are configured, the orphan stratum can be set to 1. These are the same considerations that guide the local clock driver stratum selection.

		
A orphan parent with no sources shows reference ID LOOP if
			operating at stratum 1 and 127.0.0.1 (Unix loopback address) otherwise.
			While ordinary NTP clients use a selection metric based on delay
			and dispersion, orphan children use a metric computed from the IP
			address of each core server. Each orphan child chooses the orphan
			parent as the root server with the smallest metric.

		
For orphan mode to work well, each core server with available sources should operate at the same stratum. All core servers and orphan children should include the same tos command in the configuration file. Each orphan child should include in the configuration file all root servers.

		

				gif
		

		
For example, consider the peer network configuration above, where two or more campus primary or secondary (stratum 2) servers are configured with reference clocks or public Internet primary servers and with each other using symmetric modes. With this configuration a server that loses all sources continues to discipline the system clock using the other servers as backup. Only the core servers and orphan children need to be enabled for orphan mode.

		

			gif
		

		
For broadcast networks each core server is configured in both broadcast server and broadcast client modes as shown above. Orphan children operate as broadcast clients of all core servers. As in peer networks, the core servers back up each other and only they and the orphan children need to be enabled for orphan mode.

		
In normal operation subnet hosts operate below stratum 5, so the subnet is automatically configured as described in the NTP specification. If all UTC sources are lost, all core servers become orphans and the orphan children will select the same root server to become the orphan parent.

		
Burst Options

		
There are two burst options where a single poll event triggers a burst of eight packets at 2-s intervals instead of the normal one packet. They should be used only with the server and pool commands, but not with reference clock drivers nor symmetric peers. The burst option sends a burst when the server is reachable, while the iburst option sends a burst when the server is unreachable. Each mode is independently of the other and both can be used at the same time. In either mode the client sends one packet, waits for the reply, then sends the remaining packets in the burst.  This may be useful to allow a modem to complete a call.

		
In both modes received server packets update the clock filter, which selects the best (most accurate) time values. When the last packet in the burst is sent, the next received packet updates the system variables and adjusts the system clock as if only a single packet exchange had occurred.

		
The iburst option is useful where the system clock must be set quickly or when the network attachment requires an initial calling or training sequence. The burst is initiated only when the server first becomes reachable. This improves accuracy with intermittent connections typical of PPP and ISDN services. Outliers due to initial dial-up delays, etc., are avoided and the client sets the clock within a few seconds after the first received packet.

		
The burst option can be configured in cases of excessive network
			jitter or when the network attachment requires an initial calling or training
			sequence. The burst is initiated at each poll interval when the server is
			reachable. The number of packets in the burst is determined by the poll interval
			so that the average interval between packets is no less than 16. At a poll
			interval of 16 s, only one packet is sent in the burst; at 32 s, two packets
			are sent and so forth until at 128 s and above eight packets are sent.

Synopsis

		
The NTP configuration process is driven by a phrase-structure grammar which is used to specify the format of the configuration commands and the actions needed to build an abstract syntax tree (AST). The grammar is fed to a parser generator (Bison) which produces a parser for the configuration file.

		
The generated parser is used to parse an NTP configuration file and check it for syntax and semantic errors. The result of the parse is an AST, which contains a representation of the various commands and options. This AST is then traversed to set up the NTP daemon to the correct configuration.

		
This document is intended for developers who wish to modify the configuration code and/or add configuration commands and options. It contains a description of the files used in the configuration process as well as guidelines on how to construct them.

		
Files

		
A brief description of the files used by the configuration code is given below:

		

			
				

					File
					Description
				

				

					ntp_config.y
					This file is a Bison source file that contains the phrase-structure grammar and the actions that need to be performed to generate an AST.
				

				

					ntp_config.c
					This file contains the major chunk of the configuration code. It contains all the functions that are called for building the AST as well as the functions that are needed for traversing the AST.
				

				

					ntp_config.h
					This file is the header file for ntp_config.c. It mainly contains the structure definitions needed to build the AST. 
				

				

					ntp_scanner.c
					This file contains the code for a simple lexical analyzer. This file is directly included into the ntp_config.c file since this code is only used by the configuration code. The most important function in this file is yylex, which is called by the generated parser to get the next token on the input line.
				

				

					ntp_data_structures.c
					This file contains a generic implementation of a priority queue and a simple queue. This code can be used to create a queue for any structure.
				

				

					ntp_data_structures.h
					This header file contains the structure declarations and function prototypes needed to use the data structures defined in ntp_data_structures.c. This file forms the public interface of the data structures.
				

				

					ntp_config.tab.c
					This file is generated by Bison from the ntp_config.y file. This file is also included directly into the configuration code.

The scanner reads in an NTP configuration file and converts it into tokens. The Bison generated parser reads these tokens and converts them into an AST. The AST traverser consists of a set of functions that configure parts of NTP on the basis of what is on the tree. A more detailed description of these parts and the files used is given below:

		
Detailed Description

		

			
ntp_scanner.c
			
This file contains the scanner. The scanner is a small program that converts an input NTP configuration file into a set of tokens that correspond to lexemes in the input. Lexemes are strings in the input, delimited by whitespace and/or special characters. Tokens are basically unique integers that represent these lexemes. A different token is generated for each reserved word and special character in the input. There are two main functions in the public interface of this file:
			
int yylex()
			
This function is called yylex for historical reasons; lex is a program that takes a set of regular expressions and generates a scanner that returns tokens corresponding to those regular expressions. The name of the generated function is called yylex. We aren't using lex because it requires linking against an external library and we didn't want to increase the compile-time requirements of NTP.
			
History lessons aside, this function basically checks to see if the next input character is a special character as defined in the array char special_char[]. (The function int is_special(char ch), can be used for this.) If yes, the special character is returned as the token. If not, a set of characters is read until the next whitespace or special character is encountered. This set of characters forms the lexeme; yylex then checks whether this lexeme is an integer, a double, an IP address or a reserved word. If yes, the corresponding token is returned. If not, a token for a string is returned as the default token.
			
struct state *create_keyword_scanner(struct key_tok *keyword_list)
			
This function takes a list of (keyword, token) pairs and converts them into a trie that can recognize the keywords (reserved words). Every time the scanner reads a lexeme, it compares it against the list of reserved words. If it finds a match, it returns the corresponding token for that keyword.
			
ntp_data_structures.c
			
This file contains an implementation of a generic priority queue and FIFO queue. By generic, we mean that these queues can hold element of any type (integers, user-defined structs, etc.), provided that these elements are allocated on the heap using the function void *get_node(size_t size). Note that the prototype for this function is exactly the same as that of malloc and that it can be used in the exact same way. Behind the scenes, get_node calls malloc to allocate size plus some extra memory needed for bookkeeping. The allocated memory can be freed using the function void free_node (void *my_node). In addition to these two functions, the public interface of this file contains the following functions:
			
queue *create_priority_queue(int (*get_order)(void *, void*))
			
This function creates a priority queue in which the order of the elements is determined by the get_order function that is passed as input to the priority queue. The get_order function should return positive if the priority of the first element is less than the priority of the second element.
			
queue *create_queue(void)
			
This function creates a FIFO queue. It basically calls the create_priority_queue function with the get_fifo_order function as its argument.
			
void destroy_queue(queue *my_queue)
			
This function deletes my_queue and frees up all the memory allocated to it an its elements.
			
int empty(queue *my_queue)
			
This function checks to see if my_queue is empty. Returns true if my_queue does not have any elements, else it returns false.
			
queue *enqueue(queue *my_queue, void *my_node)
			
This function adds an element, my_node, to a queue, my_queue. my_node must be allocated on the heap using the get_node function instead of malloc.
			
void *dequeue(queue *my_queue)
			
This function returns the element at the front of the queue. This element will be element with the highest priority.
			
int get_no_of_elements(queue *my_queue)
			
This function returns the number of elements in my_queue.
			
void append_queue(queue *q1, queue *q2)
			
This function adds all the elements of q2 to q1. The queue q2 is destroyed in the process.
			
ntp_config.y
			
This file is structured as a standard Bison file and consists of three main parts, separated by %%:
		

		
    
			
  1. The prologue and bison declarations: This section contains a list of the terminal symbols, the non-terminal symbols and the types of these symbols.
    2. 
			
  2. The rules section: This section contains a description of the actual phrase-structure rules that are used to parse the configuration commands. Each rule consists of a left-hand side (LHS), a right-hand side (RHS) and an optional action. As is standard with phrase-structure grammars, the LHS consists of a single non-terminal symbol. The RHS can contain both terminal and non-terminal symbols, while the optional action can consist of any arbitrary C code.
    3. 
			
  3. The epilogue: This section is left empty on purpose. It is traditionally used to code the support functions needed to build the ASTs Since, we have moved all the support functions to ntp_config.c, this section is left empty.
    4.  
		

		
Prologue and Bison Declarations

		
All the terminal symbols (also known as tokens) have to be declared in the prologue section. Note that terminals and non-terminals may have values associated with them and these values have types. (More on this later). An unnamed union has to be declared with all the possible types at the start of the prologue section. For example, we declare the following union at the start of the ntp_config.y file:

			
%union {

					    char *String;

					    double Double;

					    int Integer;

					    void *VoidPtr;

					    queue *Queue;

					    struct attr_val *Attr_val;

					    struct address_node *Address_node;

					    struct setvar_node *Set_var;

					    /* Simulation types */

					    server_info *Sim_server;

					    script_info *Sim_script;

						}

		
Some tokens may not have any types. For example, tokens that correspond to reserved words do not usually have types as they simply indicate that a reserved word has been read in the input file. Such tokens have to be declared as follows:

			
%token T_Discard

						%token T_Dispersion

		
Other tokens do have types. For example, a T_Double token is returned by the scanner whenever it sees a floating-point double in the configuration file. The value associated with the token is the actual number that was read in the configuration file and its type (after conversion) is double. Hence, the token T_Double will have to be declared as follows in the prologue of ntp_config.y file:

			
%token <Double> T_Double 

		
Note that the declaration given in the angled brackets is not double but Double, which is the name of the variable given in the %union {} declaration above.

		
Finally, non-terminal symbols may also have values associated with them, which have types. This is because Bison allows non-terminal symbols to have actions associated with them. Actions may be thought of as small functions which get executed whenever the RHS of a non-terminal is detected. The return values of these functions are the values associated with the non-terminals. The types of the non-terminals are specified with a %type declaration as shown below:

			
%type <Queue> address_list

					%type <Integer> boolean

		
The %type declaration may be omitted for non-terminals that do not return any value and do not have type information associated with them.

		
The Rules Section 

		
The rule section only consists of phrase-structure grammar rules. Each rule typically has the following format:

			
LHS : RHS [{ Actions }]

					    ;

		
where LHS consists of a single non-terminal symbol and the RHS consists of one or more terminal and non-terminal symbols. The Actions are optional and may consist of any number of arbitrary C statements. Note that Bison can only process LALR(1) grammars, which imposes additional restrictions on the kind of rules that can be specified. Examples of rules are shown below:

			
orphan_mode_command

					    : T_Tos tos_option_list

					        { append_queue(my_config.orphan_cmds, $2); }

					    ;

			
tos_option_list

					    : tos_option_list tos_option { $$ = enqueue($1, $2); }

					    | tos_option { $$ = enqueue_in_new_queue($1); }

					    ;

		
The $n notation, where n is an integer, is used to refer to the value of a terminal or non-terminal symbol. All terminals and non-terminal symbols within a particular rule are numbered (starting from 1) according to the order in which they appear within the RHS of a rule. $$ is used to refer to the value of the LHS terminal symbol - it is used to return a value for the non-terminal symbol specified in the LHS of the rule.

		
Invoking Bison 

		
Bison needs to be invoked in order to convert the ntp_config.y file into a C source file. To invoke Bison, simply enter the command:

		
bison ntp_config.y

		
at the command prompt. If no errors are detected, an ntp_config.tab.c file will be generated by default. This generated file can be directly included into the ntp_config.c file.

		
If Bison report shift-reduce errors or reduce-reduce errors, it means that the grammar specified using the rules in not LALR(1). To debug such a grammar, invoke Bison with a -v switch, as shown below. This will generate a ntp_config.output file, which will contain a description of the generated state machine, together with a list of states that have shift-reduce/reduce-reduce conflicts. You can then change the rules to remove such conflicts.

		
bison -v ntp_config.y

		
For more information, refer to the Bison manual.

		
ntp_config.c

		
This file contains the major chunk of the configuration code including all the support functions needed for building and traversing the ASTs. As such, most of the functions in this file can be divided into two groups:

		
    
			
  1. Functions that have a create_ prefix. These functions are used to build a node of the AST.
    2.  
			
  2. Functions that have a config_ prefix. These functions are used to traverse the AST and configure NTP according to the nodes present on the tree.
    3.  
		

		
Guidelines for Adding Configuration Commands

		
The following steps may be used to add a new configuration command to the NTP reference implementation:

		
    
			
  1. Write phrase-structure grammar rules for the syntax of the new command. Add these rules to the rules section of the ntp_config.y file. 
    2. 
			
  2. Write the action to be performed on recognizing the rules. These actions will be used to build the AST.
    3. 
			
  3. If new reserved words are needed, add these to the struct key_tok keyword_list[]structure in the ntp_config.c file. This will allow the scanner to recognize these reserved words and generate the desired tokens on recognizing them.
    4.  
			
  4. Specify the types of all the terminals and non-terminal symbols in the prologue section of the ntp_config.c file.
    5.  
			
  5. Write a function with a config_ prefix that will   be executed for this new command. Make sure this function is called in the config_ntpd()function.
    6.

PPSAPI Interface for Precision Time Signals

Introduction

		
RFC-2783 describes the PPSAPI application programming interface for external precision time signals, such as the pulse-per-second (PPS) signal generated by some radio clocks and cesium oscillators. The PPSAPI provides a generic capability in the ubiquitous Unix kernel which can be used for a wide variety of measurement applications, including network time synchronization and related experiments. The hardware to do this requires only a serial port and a modem control lead, such as the data carrier detect (DCD) lead, which can be driven by an external source via a level converter/pulse generator such as described on the Pulse-per-second (PPS) Signal Interfacing page. In some systems a parallel port can be used for the same purpose.

		
The PPSAPI interface defined in RFC-2783 is the only PPS interface supported in NTP Version 4. The PPSAPI is supported in stock FreeBSD and, with the addition of the PPSkit kernel module, in Linux.

		
The special header file /usr/include/sys/timepps.h implements the PPSAPI using whatever primitives are available in each archeticture and operating system. It obsoletes previous APIs based on the tty_clock and ppsclock line disciplines and streams modules, which are no longer supported.

		
The PPS Clock Discipline driver (type 22) uses the PPSAPI in conjunction with a local radio clock or remote NTP server as a reference clock. The driver can also use the PPSAPI as an interface directly to the kernel PPS facility as described on the Kernel Model for Precision Timekeeping page.

		
PPSAPI Application Program Interface

		
The PPSAPI interface provides the following functions:

		

			
time_pps_create
			
Creates a PPS interface instance and returns a handle to it.
			
time_pps_destroy
			
Destroys a PPS interface and returns the resources used.
			
time_pps_setparams
			
Sets the parameters associated with a PPS interface instance, including offsets to be automatically added to captured timestamps.
			
time_pps_getparams
			
Returns the parameters associated with a PPS interface instance.
			
time_pps_getcap
			
Returns the capabilities of the current interface and kernel implementation.
			
time_pps_fetch
			
Returns the current timestamps associated with a PPS interface instance in either nanoseconds and nanoseconds (Unix timespec) or seconds and fraction (NTP) format.
			
time_pps_kcbind
			
If kernel PPS processing is supported, this binds the support to the associated PPS interface instance.
		

		
The entire PPS interface functionality is currently provided by inline code in the timepps.h header file. While not all implementations support the full PPSAPI specification, they do support all the functions required for the PPS driver described next. The FreeBSD, Linux and Solaris implementations can be used with the stock kernels provided with those systems; however, the Tru64 and SunOS kernels require additional functions not provided in the stock kernels. Solaris users are cautioned that these functions operate improperly in Solaris versions prior to 2.8 with patch Generic_108528-02. Header files for other systems can be found via the web at nanokernel.tar.gz.

Initial Startup

		
This page discusses ntpd program monitoring and debugging techniques using the ntpq - standard NTP query program, either on the local server or from a remote machine. In special circumstances the ntpdc - special NTP query program, can be useful, but its use is not covered here. The ntpq program implements the management functions specified in the NTP specification RFC-1305, Appendix A. It is used to read and write the variables defined in the NTP Version 4 specification now navigating the standards process. In addition, the program can be used to send remote configuration commands to the server.

		
The ntpd daemon can operate in two modes, depending on the presence of the -d command-line option. Without the option the daemon detaches from the controlling terminal and proceeds autonomously. With one or more -d options the daemon does not detach and generates special trace output useful for debugging. In general, interpretation of this output requires reference to the sources. However, a single -d does produce only mildly cryptic output and can be very useful in finding problems with configuration and network troubles.

		
Some problems are immediately apparent when the daemon first starts running. The most common of these are the lack of a UDP port for NTP (123) in the Unix /etc/services file (or equivalent in some systems). Note that NTP does not use TCP in any form. Also note that NTP requires port 123 for both source and destination ports. These facts should be pointed out to firewall administrators.

		
Other problems are apparent in the system log, which ordinarily shows the startup banner, some cryptic initialization data and the computed precision value. Event messages at startup and during regular operation are sent to the optional protostats monitor file, as described on the Event Messages and Status Words page. These and other error messages are sent to the system log, as described on the ntpd System Log Messages page. In real emergencies the daemon will sent a terminal error message to the system log and then cease operation.

		
The next most common problem is incorrect DNS names. Check that each DNS name used in the configuration file exists and that the address responds to the Unix ping command. The Unix traceroute or Windows tracert utility can be used to verify a partial or complete path exists. Most problems reported to the NTP newsgroup are not NTP problems, but problems with the network or firewall configuration.

		
Verifying Correct Operation

		
Unless using the iburst option, the client normally takes a few
			minutes to synchronize to a server. If the client time at startup happens
			to be more than 1000 s distant from NTP time, the daemon exits with a message
			to the system log directing the operator to manually set the time within 1000
			s and restart. If the time is less than 1000 s but more than 128 s distant,
			a step correction occurs and the daemon restarts automatically.

		
When started for the first time and a frequency file is not present, the
			daemon enters a special mode in order to calibrate the frequency. This takes
			900 s during which the time is not disciplined. When calibration is complete,
			the daemon creates the frequency file and enters normal mode to amortize whatever
			residual offset remains.

		
The ntpq commands pe, as and rv are
			normally sufficient to verify correct operation and assess nominal performance.
			The pe command displays a list showing
			the DNS name or IP address for each association along with selected status
			and statistics variables. The first character in each line is the tally code,
			which shows which associations are candidates to set the system clock and
			of these which one is the system peer. The encoding is shown in the select
			field of the peer status word.

		
The as command displays a list of associations and association identifiers. Note the condition column, which reflects the tally code. The rv command displays the system variables billboard, including the system status word. The rv assocID command, where assocID is the association ID, displays the peer variables billboard, including the peer status word. Note that, except for explicit calendar dates, times are in milliseconds and frequencies are in parts-per-million (PPM).

		
A detailed explanation of the system, peer and clock variables in the billboards is beyond the scope of this page; however, a comprehensive explanation for each one is in the NTPv4 protocol specification. The following observations will be useful in debugging and monitoring.

		
    
			
  1. The server has successfully synchronized to its sources if the leap peer
				variable has value other than 3 (11b) The client has successfully synchronized
				to the server when the leap system variable has value other than
				3.
			
  2. The reach peer variable is an 8-bit shift register displayed in octal format. When a valid packet is received, the rightmost bit is lit. When a packet is sent, the register is shifted left one bit with 0 replacing the rightmost bit. If the reach value is nonzero, the server is reachable; otherwise, it is unreachable. Note that, even if all servers become unreachable, the system continues to show valid time to dependent applications.
			
  3. A useful indicator of miscellaneous problems is the flash peer variable, which shows the result of 13 sanity tests. It contains the flash status word bits, commonly called flashers, which displays the current errors for the association. These bits should all be zero for a valid server.
			
  4. The three peer variables filtdelay, filtoffset and filtdisp show the delay, offset and jitter statistics for each of the last eight measurement rounds. These statistics and their trends are valuable performance indicators for the server, client and the network. For instance, large fluctuations in delay and jitter suggest network congestion. Missing clock filter stages suggest packet losses in the network.
			
  5. The synchronization distance, defined as one-half the delay plus the dispersion, represents the maximum error statistic. The jitter represents the expected error statistic. The maximum error and expected error calculated from the peer variables represents the quality metric for the server. The maximum error and expected error calculated from the system variables represents the quality metric for the client. If the root synchronization distance for any server exceeds 1.5 s, called the select threshold, the server is considered invalid.

		
Large Frequency Errors

		
The frequency tolerance of computer clock oscillators varies widely, sometimes above 500 PPM. While the daemon can handle frequency errors up to 500 PPM, or 43 seconds per day, values much above 100 PPM reduce the headroom, especially at the lowest poll intervals. To determine the particular oscillator frequency, start ntpd  using the noselect option with the  server configuration command.

		
Record the time of day and offset displayed by the ntpq pe command. Wait for an hour or so and record the time of day and offset. Calculate the frequency as the offset difference divided by the time difference. If the frequency is much above 100 PPM, the tickadj program might be useful to adjust the kernel clock frequency below that value. For systems that do not support this program, this might be one using a command in the system startup file.

		
Access Controls

		
Provisions are included in ntpd for access controls which deflect unwanted traffic from selected hosts or networks. The controls described on the Access Control Options include detailed packet filter operations based on source address and address mask. Normally, filtered packets are dropped without notice other than to increment tally counters. However, the server can be configured to send a "kiss-o'-death" (KOD) packet to the client either when explicitly configured or when cryptographic authentication fails for some reason. The client association is permanently disabled, the access denied bit (TEST4) is set in the flash variable and a message is sent to the system log.

		
The access control provisions include a limit on the packet rate from a
			host or network. If an incoming packet exceeds the limit, it is dropped and
			a KOD sent to the source. If this occurs after the client association has
			synchronized, the association is not disabled, but a message is sent to the
			system log. See the Access Control Options page
			for further information.

		
Large Delay Variations

		
In some reported scenarios an access line may show low to moderate network delays during some period of the day and moderate to high delays during other periods. Often the delay on one direction of transmission dominates, which can result in large time offset errors, sometimes in the range up to a few seconds. It is not usually convenient to run ntpd throughout the day in such scenarios, since this could result in several time steps, especially if the condition persists for greater than the stepout threshold.

		
Specific provisions have been built into ntpd to cope with these problems. The scheme is called "huff-'n-puff and is described on the Miscellaneous Options page. An alternative approach in such scenarios is first to calibrate the local clock frequency error by running ntpd in continuous mode during the quiet interval and let it write the frequency to the ntp.drift file. Then, run ntpd -q from a cron job each day at some time in the quiet interval. In systems with the nanokernel or microkernel performance enhancements, including Solaris, Tru64, Linux and FreeBSD, the kernel continuously disciplines the frequency so that the residual correction produced by ntpd is usually less than a few milliseconds.

		
Cryptographic Authentication

		
Reliable source authentication requires the use of symmetric key or public key cryptography, as described on the Authentication Options page. In symmetric key cryptography servers and clients share session keys contained in a secret key file In public key cryptography, which requires the OpenSSL software library, the server has a private key, never shared, and a public key with unrestricted distribution. The cryptographic media required are produced by the ntp-keygen program.

		
Problems with symmetric key authentication are usually due to mismatched keys or improper use of the trustedkey command. A simple way to check for problems is to use the trace facility, which is enabled using the ntpd -d command line. As each packet is received a trace line is displayed which shows the authentication status in the auth field. A status of 1 indicates the packet was successful authenticated; otherwise it has failed.

		
A common misconception is the implication of the auth bit in the enable and disable commands. This bit does not affect authentication in any way other than to enable or disable mobilization of a new persistent association in broadcast/multicast client, manycast client or symmetric passive modes. If enabled, which is the default, these associations require authentication; if not, an association is mobilized even if not authenticated. Users are cautioned that running with authentication disabled is very dangerous, since an intruder can easily strike up an association and inject false time values.

		
Public key cryptography is supported in NTPv4 using the Autokey protocol, which is described in briefings on the NTP Project page linked from www.ntp.org. Development of this protocol is mature and the ntpd implementation is basically complete. Autokey version 2, which is the latest and current version, includes provisions to hike certificate trails, operate as certificate authorities and verify identity using challenge/response identification schemes. Further details of the protocol are on the Authentication Options page. Common problems with configuration and key generation are mismatched key files, broken links and missing or broken random seed file.

		
As in the symmetric key cryptography case, the trace facility is a good way to verify correct operation. A statistics file cryptostats records protocol transactions and error messages. The daemon requires a random seed file, public/private key file and a valid certificate file; otherwise it exits immediately with a message to the system log. As each file is loaded a trace message appears with its filestamp. There are a number of checks to insure that only consistent data are used and that the certificate is valid. When the protocol is in operation a number of checks are done to verify the server has the expected credentials and its filestamps and timestamps are consistent. Errors found are reported using NTP control and monitoring protocol traps with extended trap codes shown in the Authentication Options page.

		
To assist debugging every NTP extension field is displayed in the trace along with the Autokey operation code. Every extension field carrying a verified signature is identified and displayed along with filestamp and timestamp where meaningful. In all except broadcast/multicast client mode, correct operation of the protocol is confirmed by the absence of extension fields and an auth value of one. It is normal in broadcast/multicast client mode that the broadcast server use one extension field to show the host name, status word and association ID.

		
Debugging Checklist

		
If the ntpq or ntpdc programs do not show that messages are being received by the daemon or that received messages do not result in correct synchronization, verify the following:

		
    
			
  1. Verify the /etc/services file host machine is configured to accept UDP packets on the NTP port 123. NTP is specifically designed to use UDP and does not respond to TCP.
			
  2. Check the system log for ntpd messages about configuration errors, name-lookup failures or initialization problems. Common system log messages are summarized on the ntpd System Log Messages page. Check to be sure that only one copy of ntpd is running.
			
  3. Verify using ping or other utility that packets actually do make the round trip between the client and server. Verify using nslookup or other utility that the DNS server names do exist and resolve to valid Internet addresses.
			
  4. Check that the remote NTP server is up and running. The usual evidence that it is not is a Connection refused message.
			
  5. Using the ntpdc program, verify that the packets received and packets sent counters are incrementing. If the sent counter does not increment and the configuration file includes configured servers, something may be wrong in the host network or interface configuration. If this counter does increment, but the received counter does not increment, something may be wrong in the network or the server NTP daemon may not be running or the server itself may be down or not responding.
			
  6. If both the sent and received counters do increment, but the reach values in the pe billboard with ntpq continues to show zero, received packets are probably being discarded for some reason. If this is the case, the cause should be evident from the flash variable as discussed above and on the ntpq page. It could be that the server has disabled access for the client address, in which case the refid field in the ntpq pe billboard will show a kiss code. See earlier on this page for a list of kiss codes and their meaning.
			
  7. If the reach values in the pe billboard show the servers are alive and responding, note the tattletale symbols at the left margin, which indicate the status of each server resulting from the various grooming and mitigation algorithms. The interpretation of these symbols is discussed on the ntpq page. After a few minutes of operation, one or another of the reachable server candidates should show a * tattletale symbol. If this doesn't happen, the intersection algorithm, which classifies the servers as truechimers or falsetickers, may be unable to find a majority of truechimers among the server population.
			
  8. If all else fails, see the FAQ and/or the discussion and briefings at the NTP Project page.

Introduction

		
Many radio clocks used as a primary reference source for NTP servers produce
			a pulse-per-second (PPS) signal that can be used to improve accuracy to a
			high degree. However, the signals produced are usually incompatible with the
			modem interface signals on the serial ports used to connect the signal to
			the host. The gadget box consists of a handful of electronic components assembled
			in a small aluminum box. It includes level converters and a optional radio
			modem designed to decode the radio timecode signals transmitted by the Canadian
			time and frequency station CHU. A complete set of schematics, PCB artwork,
			drill templates can be obtained via the web from ftp.udel.edu as gadget.tar.Z.

		
The gadget box is assembled in a 5"x3"x2" aluminum minibox containing the level converter and modem circuitry. It includes two subcircuits. One of these converts a TTL positive edge into a fixed-width pulse at EIA levels and is for use with a timecode receiver or oscillator including a TTL PPS output. The other converts the timecode modulation broadcast by Canadian time/frequency standard station CHU into a 300-bps serial character stream at EIA levels and is for use with the Radio CHU Audio Demodulator/Decoder driver.

Introduction

			
Most radio clocks are connected using a serial port operating at speeds of 9600 bps. The accuracy using typical timecode formats, where the on-time epoch is indicated by a designated ASCII character like carriage-return <cr>, is normally limited to a hundred microseconds. Using carefuly crafted averaging techniques, the NTP algorithms can whittle this down to a few tens of microseconds. However, some radios produce a PPS signal which can be used to improve the accuracy to few microseconds. This page describes the hardware and software necessar for NTP to use the PPS signal.

Gadget Box

			
The PPS signal can be connected in either of two ways: via the DCD data carrier detect pin of a serial port or via the ACK acknowledge pin of a parallel port, depending on the hardware and operating system. Note that NTP no longer supports connection via the RD data pin of a serial port.

			
However, the PPS signal levels are usually incompatible with serial port levels. The gadget box consists of a handful of electronic components assembled in a small aluminum box. It includes level converters and a optional modem designed to decode the radio timecode signals transmitted by Canadian time and frequency station CHU. This can be used with the Radio CHU Audio Demodulator/Decoder. A complete set of schematics, PCB artwork and drill templates can be obrtained via the web at gadget.tar.Z.

			
Operating System Support

			
Both the serial and parallel port connection require operating system support, which is available in only a few operating systems, including FreeBSD, Linux (with PPSkit patch) and Solaris. Support on an experimental basis is available for several other systems, including SunOS and HP/Compaq/Digital Tru64. The kernel interface described on the PPSAPI Interface for Precision Time Signals page is the only interface currently supported. Older PPS interfaces based on the ppsclock and tty_clk streams modules are no longer supported.

			
PPS Driver

			
PPS support requires the PPS driver (described on the Type 22 PPS Clock Discipline page. The driver operates in conjunction with a prefer peer, as described in the Mitigation Rules and the prefer Keyword page. The prefer peer is ordinarily the radio clock that provides the PPS signal, but in principle another radio clock or remote Internet server could be designated prerred. A source is desgnated prefer using the prefer keyword, as described on the Mitigation Rules and the prefer keyword page. Only one source can be designated preferred. PPS signals are processed by the PPS driver and other clock drivers which might be involved need not know or care about PPS capability. Note that the pps configuration command has been obsoleted by this driver.

			
Using the Pulse-per-Second (PPS) Signal

			
The PPS signal  can be used in two ways, one using the NTP grooming and mitigations algorithms and the other using PPS signal support in the kernel, as described in the Kernel Model for Precision Timekeeping page. In either case, the PPS signal must be present and within nominal jitter and wander tolerances. In addition, the PPS driver and prefer peer must survive the sanity checks and intersection algorithms. Finally, the offset of the system clock relative to the prefer peer must be less than 128 ms, or well within the 0.5-s unambiguous range. The PPS peer remains active as long as these conditions are met.

			
The presence of PPS kernel support is automatically detected during the NTP configuration process and supporting code automatically compiled. When kernel PPS support is enabled, the PPS driver can direct the signal directly to the kernel. Note that the PPS driver does not normally enable the PPS kernel, since performance is generally better with older systems. However, the kernel can be enabled by a driver fudge flag if necessary. This is advised for newer machines in the Pentium class.

			
The kernel maintains a watchdog timer for the PPS signal; if the signal has not been heard or is out of tolerance for more than some interval, currently two minutes, the kernel discipline is disabled and operation continues as if it were not present.

tickadj - set time-related kernel variables

		
Last update: 18:53 UTC Wednesday, January 16, 2008

		

		
Synopsis

		
tickadj [ tick ]

		
tickadj [ -Aqs ] [ -a tickadj ] [ -t tick ]

		
Description

		
The tickadj program reads, and optionally modifies, several timekeeping-related variables in older kernels that do not have support for precision ttimekeeping, including HP-UX, SunOS, Ultrix, SGI and probably others. Those machines provide means to patch the kernel /dev/kmem. Newer machines with kernel time support, including Solaris, Tru64, FreeBSD and Linux, should NOT use the program, even if it appears to work, as it will destabilize the kernel time support. Use the ntptime program instead.

		
The particular variables that can be changed with tickadj include tick, which is the number of microseconds added to the system time for a clock interrupt, tickadj, which sets the slew rate and resolution used by the adjtime system call, and dosynctodr, which indicates to the kernels on some machines whether they should internally adjust the system clock to keep it in line with time-of-day clock or not.

		
On Linux, only the tick variable is supported and the only allowed argument is the tick value.

		
By default, with no arguments, tickadj reads the variables of interest in the kernel and displays them. At the same time, it determines an "optimal" value for the value of the tickadj variable if the intent is to run the ntpd Network Time Protocol (NTP) daemon, and prints this as well. Since the operation of tickadj when reading the kernel mimics the operation of similar parts of the ntpd program fairly closely, this can be useful when debugging problems with ntpd.

		
Note that tickadj should be run with some caution when being used for the first time on different types of machines. The operations which tickadj tries to perform are not guaranteed to work on all Unix machines and may in rare cases cause the kernel to crash.

		
Command Line Options

		

			
-a tickadj
			
Set the kernel variable tickadj to the value tickadjspecified.
			
-A
			
Set the kernel variable tickadj to an internally computed "optimal" value.
			
-t tick
			
Set the kernel variable tick to the value tick specified.
			
-s
			
Set the kernel variable dosynctodr to zero, which disables the hardware time-of-year clock, a prerequisite for running the ntpd daemon under SunOS 4.x.
-q
			
Normally, tickadj is quite verbose about what it is doing. The -q flag tells it to shut up about everything except errors.

Bugs

		Fiddling with kernel variables at run time as a part of ordinary operations is a hideous practice which is only necessary to make up for deficiencies in the implementation of adjtime in many kernels and/or brokenness of the system clock in some vendors' kernels. It would be much better if the kernels were fixed and the tickadj program went away.

		Making PARSE Clocks
		
	

	
		
How to build new PARSE clocks

		
Here is an attempt to sketch out what you need to do in order to add another clock to the parse driver: Currently the implementation is being cleaned up - so not all information in here is completely correct. Refer to the included code where in doubt.

		
Prerequisites:

		
    
			
  • Does the system you want the clock connect to have the include files termio.h or termios.h ? (You need that for the parse driver)
		

		
What to do:

		
Make a conversion module (libparse/clk_*.c)

		
    
			
  1. What ist the time code format ?
				
      
					
    • find year, month, day, hour, minute, second, status (synchronised or not), possibly time zone information (you need to give the offset to UTC) You will have to convert the data from a string into a struct clocktime:
						
            struct clocktime                /* clock time broken up from time code */
      {
	long day;
	long month;
	long year;
	long hour;
	long minute;
	long second;
	long usecond;
	long utcoffset;       /* in seconds */
	time_t utcoffset;     /* true utc time instead of date/time */
	long flags;           /* current clock status */
      };

      
						
      Conversion is usually simple and straight forward. For the flags following values can be OR'ed together:
      
						
           PARSEB_ANNOUNCE           switch time zone warning (informational only)
     PARSEB_POWERUP            no synchronisation - clock confused (must set then)
     PARSEB_NOSYNC             timecode currently not confirmed (must set then)
                               usually on reception error when there is still a
                               chance the the generated time is still ok.

     PARSEB_DST                DST in effect (informational only)
     PARSEB_UTC                timecode contains UTC time (informational only)
     PARSEB_LEAPADD            LEAP addition warning (prior to leap happening - must set when imminent)
			       also used for time code that do not encode the
			       direction (as this is currently the default).
     PARSEB_LEAPDEL            LEAP deletion warning (prior to leap happening - must set when imminent)
     PARSEB_ALTERNATE          backup transmitter (informational only)
     PARSEB_POSITION           geographic position available (informational only)
     PARSEB_LEAPSECOND         actual leap second (this time code is the leap
                               second - informational only)

      
						
      These are feature flags denoting items that are supported by the clock:
      
						
           PARSEB_S_LEAP             supports LEAP - might set PARSEB_LEAP
     PARSEB_S_ANTENNA          supports ANTENNA - might set PARSEB_ALTERNATE
     PARSEB_S_PPS              supports PPS time stamping
     PARSEB_S_POSITION         supports position information (GPS)
   
      
						
      If the utctime field is non zero this value will be take as time code value. This allows for conversion routines that already have the utc time value. The utctime field gives the seconds since Jan 1st 1970, 0:00:00. The useconds field gives the respective usec value. The fields for date and time (down to second resolution) will be ignored.
      
						
      Conversion is done in the cvt_* routine in parse/clk_*.c files. look in them for examples. The basic structure is:
      
						
           struct clockformat <yourclock>_format = {
       lots of fields for you to fill out (see below)
     };

     static cvt_<yourclock>()
       ...
     {
       if (<I do not recognize my time code>) {
         return CVT_NONE;
       } else {
         if (<conversion into clockformat is ok>) {
           <set all necessary flags>;
           return CVT_OK;
         } else {
           return CVT_FAIL|CVT_BADFMT;
         }
       }

      
						
      The struct clockformat is the interface to the rest of the parse driver - it holds all information necessary for finding the clock message and doing the appropriate time stamping.
      
						
      struct clockformat
{
  u_long (*input)();
  /* input routine - your routine - cvt_<yourclock> */
  u_long (*convert)();
  /* conversion routine - your routine - cvt_<yourclock> */
  /* routine for handling RS232 sync events (time stamps) - usually sync_simple */
  u_long (*syncpps)(); 
  /* PPS input routine - usually pps_one */
  void           *data;
  /* local parameters - any parameters/data/configuration info your conversion
     routine might need */
  char           *name;
  /* clock format name - Name of the time code */
  unsigned short  length;
  /* maximum length of data packet for your clock format */
  u_long   flags;
 /* information for the parser what to look for */
};

      
						
      The above should have given you some hints on how to build a clk_*.c file with the time code conversion. See the examples and pick a clock closest to yours and tweak the code to match your clock.
      
						
      In order to make your clk_*.c file usable a reference to the clockformat structure must be put into parse_conf.c.
      
				
    
			
  2. TTY setup and initialisation/configuration will be done in ntpd/refclock_parse.c.
				
      
					
    • Find out the exact tty settings for your clock (baud rate, parity, stop bits, character size, ...) and note them in terms of termio*.h c_cflag macros.
					
    • in ntpd/refclock_parse.c fill out a new the struct clockinfo element (that allocates a new "IP" address - see comments) (see all the other clocks for example)

Well, this is very sketchy, i know. But I hope it helps a little bit. The best way is to look which clock comes closest to your and tweak that code.

		
Two sorts of clocks are used with parse. Clocks that automatically send their time code (once a second) do not need entries in the poll routines because they send the data all the time. The second sort are the clocks that need a command sent to them in order to reply with a time code (like the Trimble clock).

		
For questions: kardel@acm.org.

		
Please include an exact description on how your clock works. (initialisation, TTY modes, strings to be sent to it, responses received from the clock).

External Clock Discipline and the Local Clock Driver

		
Last update: 18:38 UTC Thursday, July 28, 2005

		

		
The NTPv4 implementation includes provisions for an external clock, where
			the system clock is implemented by some external hardware device.
			One implementation might take the form of a bus peripheral with a high resolution
			counter disciplined by a GPS receiver, for example. Another implementation
			might involve another synchronization protocol, such as the Digital Time Synchronization
			Service (DTSS), where the system time is disciplined to this protocol and
			NTP clients of the server obtain synchronization indirectly via the server.
			A third implementation might be a completely separate clock discipline algorithm
			and synchronization protocol, such as the Lockclock algorithm used
			with NIST Automated Computer Time Service (ACTS) modem synchronized time.

		
When external clocks are used in conjunction with NTP service, some way needs to be provided for the external clock driver and NTP daemon ntpd to communicate and determine which discipline is in control. This is necessary in order to provide backup, for instance if the external clock or protocol were to fail and synchronization service fall back to other means, such as a local reference clock or another NTP server. In addition, when the external clock and driver are in control, some means needs to be provided for the clock driver to pass on status information and error statistics to the NTP daemon.

		
Control and monitoring functions for the external clock and driver are implemented using the Local Clock (type 1) driver and the ntp_adjtime() system call. This system call is implemented by special kernel provisions included in the kernel of several operating systems, including Solaris, Tru64, FreeBSD and Linux, and possibly others. When the external clock is disabled or not implemented, the system call is used to pass time and frequency information, as well as error statistics, to the kernel. Besides disciplining the system time, the same interface can be used by other applications to determine the operating parameters of the discipline.

		
When the external clock is enabled, ntpd does not discipline the system clock, nor does it maintain the error statistics. In this case, the external clock and driver do this using mechanisms unknown to ntpd; however, in this case the kernel state variables are retrieved at 64-s intervals by the Local Clock driver and used by the clock selection and mitigation algorithms to determine the system variables presented to other NTP clients and peers. In this way, downstream clients and servers in the NTP subnet can make an intelligent choice when more than one server is available.

		
In order to implement a reliable mitigation between ordinary NTP sources and the external clock source, a protocol is necessary between the local clock driver and the external clock driver. This is implemented using Boolean variables and certain bits in the kernel clock status word. The Boolean variables include the following:

		
ntp_enable. set/reset by the enable command. enables ntpd
			clock discipline

		
ntp_control. set during initial configuration if kernel support is available

		
kern_enable Set/reset by the enable command

		
If the kern_enable switch is set, the daemon computes the offset,
			frequency, maximum error, estimated error, time constant and status bits,
			then provides them to the kernel via ntp_adjtime(). If this switch
			is not set, these values are not passed to the kernel; however, the daemon
			retrieves their present values and uses them in place of the values computed
			by the daemon.

		
The pps_update bit set in the protocol routine if the prefer peer has survived and has offset less than 128 ms; otherwise set to zero.

		
The PPS control Updated to the current time by kernel support if
			the PPS signal is enabled and working correctly. Set to zero in the adjust
			routine if the interval since the last update exceeds 120 s.

		
The ntp_enable and kern_enable are set by the configuration module. Normally, both switches default on, so the daemon can control the time and the kernel discipline can be used, if available. The pps_update switch is set by the protocol module when it believes the PPS provider source is legitimate and operating within nominals. The ntp_control switch is set during configuration by interrogating the kernel. If both the kern_enable and ntp_control switches are set, the daemon disciplines the clock via the kernel and the internal daemon discipline is disabled.

		
The external clock driver controls the system time and clock selection in the following way. Normally, the driver adjusts the kernel time using the ntp_adjtime() system call in the same way as the daemon. In the case where the kernel discipline is to be used intact, the clock offset is provided in this call and the loop operates as specified. In the case where the driver steers only the frequency, the offset is specified as zero.

On some systems, including AIX, the compiler quits on the ntp_refclock.c
file when processing the refclock_report() routine. The problem, which
is eithre a feature or a bug, has to do with an unwanted promotion of
the u_char argument to an int and a failure of the compiler to recognize
the preceding prototype. A workaround is to use ANSI syntax to delare
the arguments. Since ANSI compilers are not universally available, this
syntax can't be used in the stock distribution.

Subject: time and AIX 3.2.5 raw tty bug
 
This posting isn't strictly about NTP, any program that may stop the
clock or set the clock backwards is subject to the AIX 3.2.5 bug.
 
On AIX 3.2.5, there is a bug in the tty driver for a raw device which
may crash the box under certain conditions: basically a read() on a
raw tty in effect, a character was read but not as many as specified
by VMIN when a read timeout occurred. VTIME specifies the timeout. See
the AIX manual page on termios.h or that include file. for Information
on VMIN (or MIN) VTIME (or TIME).
 
A remedy other than to not use raw tty's is to apply patch U435110.
 
Details of the problem report follow.

A bug in SunOS 4.1.1 results in the kernel time losing 1 microsecond
per tick of the system clock. The bug was fixed (bugid 1094383) for
SunOS 4.1.1 and corrected in SunOS 4.1.3. The easiest way to fix this
is to replace the 4.1.1 binary clock.o with the corresponding 4.1.3
binary. Without this change it is necessary to use the tickadj program
included in this distribution with the -t 9999 option.

The tickadj option will work in all cases except when the kernel has
been modified to correct the CPU clock oscillator frequency using a
1-pps signal from a precision source. The bugfix must be installed for
this wrinkle to work properly.

INTRODUCTION:
-------------
Last revision:  06-Jul-1994

Included in this distribution of XNTP V3 is a configuration file suitable
for use under Apple's A/UX Version 3.x.x  There is also one for A/UX 2.0.1
but it has not been fully tested. To make the executables follow the steps
outlined below.

*** NOTE:  You must have gcc installed to successfully compile the current
distribution; the native cc supplied with A/UX will NOT correctly compile
this source.  See the FAQ in comp.unix.aux for places to obtain gcc from
and how to install it.

----------------------
MAKING XNTPD FOR A/UX:
----------------------

First, you need to create the makefiles (after you've downloaded the
source, of course):

    % make clean
    % make refconf

After that, you should edit Config.local to make sure that BINDIR is
correct for where you wish the programs to be "installed". The default
(and what I use) is /usr/local/etc. Make sure that DEFS_LOCAL and
CLOCKDEFS are commented out! Presently, only the LOCAL_CLOCK/REFCLOCK
clock is used and supported.


After this is done (you should be told that your system is A/UX 3), make
'xntpd' (the options to 'gcc' are held in compilers/aux3.gcc):

    % make

I do not normally use the `make install' option and so have not verified its
compatibility with A/UX.  Rather, I pull out each of the executables and
place them in the locally appropriate locations.

---------------
STARTING XNTPD:
---------------

At this point you need to set things up so that 'xntpd' is started upon
boot-up. You can do this in 1 of 2 ways: either add entries in /etc/inittab
or, more ideally, create and use an /etc/rc.local file. Since rc.local is
what I recommend, here's how you do it:

By default, A/UX doesn't have rc.local, so you'll need to add the following to
/etc/inittab:

    net6:2:wait:/etc/syslogd		# set to "wait" to run a syslog daemon
+   jmj0:2:wait:/etc/rc.local 1>/dev/syscon 2>&1	# Local stuff
    dbg2::wait:/etc/telinit v	# turn off init's verbose mode

Now, the look of a sample /etc/rc.local is as follows:

    #!/bin/sh
    :
    : rc.local
    :
    #	@(#)Copyright Apple Computer 1987	Version 1.17 of rc.sh on 91/11/08 15:56:21 (ATT 1.12)
    
    
    #	Push line discipline/set the device so it will print
    /etc/line_sane 1
    echo " "
    echo "Entering rc.local..."
    
    set `/bin/who -r`
    if [ "$7" = 2 ]
    then
        /bin/echo " now setting the time..."
        /usr/local/etc/ntpdate -s -b 
        sleep 5
    #
    # start up 'xntpd' if we want
    #
        if [ -f /etc/ntp.conf ]
        then
    	/bin/echo " setting tick and tickadj..."
    	/usr/local/etc/tickadj -t 16672 -a 54
    	sleep 5
    	/bin/echo " starting xntpd..."
    	/usr/local/etc/xntpd <&- > /dev/null 2>&1
    	sleep 5
        fi
    #
    fi
    
    echo "Leaving rc.local..."

There are a few things to notice about the above:

    o When run, 'ntpdate' forces your clock to the time returned by the
      host(s) specified by  (you'll need to replace this
      be the IP address(es) of your timehosts. This is good since it gets
      things close to start off with. You can use more than one time
      server.

    o 'tickadj' is also called. This does two things: changes the
      default value of 'tick' (which the the amount of time, in ms, that
      is added to the clock every 1/60 seconds) and changes the value
      of 'tickadj' which the the amount that is added or subtracted
      from 'tickadj' when adjtime() is called.

      Now Mac clocks are pretty bad and tend to be slow. Sooo, instead of
      having A/UX add the default of 16666ms every 1/60th of a second, you
      may want it to add more (or less) so that it keeps better time. The
      above value works for me but your "best" value may be different and
      will likely require some fooling around to find the best value. As a
      general rule of thumb, if you see 'xntpd' make a lot of negative clock
      adjustments, then your clock is fast and you'll need to _decrease_
      the value of 'tick'. If your adjustments are positive, then you need
      to increase 'tick'. To make a guess on how fast/slow your clock is,
      use 'ntpdate' to sync your clock. Now watch 'xntpd' and see how it
      operates. If, for example, it resets your clock by 1 second every 30
      minutes, then your clock is (1/(30*60)) is about 0.056% off and you'll
      need to adjust 'tick' by 16666*0.00056 or about 9 (i.e. 'tick' should
      be ~16675 if slow or ~16657 if fast)

      A/UX's default value of 'tickadj' is 1666 which is too big for
      'xntpd'... so it also needs to be adjusted. I like using larger
      values then the recommended value of 9 for 'tickadj' (although not
      anything near as big as 1666) since this allows for quick slews
      when adjusting the clock. Even with semi-large values of 'tickadj'
      (~200), getting 5ms (1/200 s) accuracy is easy.


Finally, before A/UX and 'xntpd' will work happily together, you need to
patch the kernel. This is due to the fact that A/UX attempts to keep the
UNIX-software clock and the Mac-hardware clock in sync. Neither the h/w or
the s/w clock are too accurate. Also, 'xntpd' will be attempting to adjust
the software clock as well, so having A/UX muck around with it is asking
for headaches. What you therefore need to do is tell the kernel _not_ to
sync the s/w clock with the h/w one. This is done using 'adb'. The
following is a shell script that will do the patch for you:

    #! /bin/sh
    adb -w /unix < (xntpd/refclock_parse.c):
	- Added support to supply power from RS232 with CLOCK_RAWDCF.
	  Known to work with Linux 1.2.
	- Made Linux ignore parity errors with CLOCK_RAWDCF.

Ulrich Windl  (parse/util/dcfd.c):
	- Removed conflicting prototype for Linux (sscanf)

Solaris hints and kinks



Information on compiling and executing ntpd under Solaris.


Last Updated: Sun Jun 21 01:32:18 EDT 1998,
John Hawkinson,
 <jhawk@MIT.EDU>


If you're not running Solaris 2.5.1 or later, it is likely
that you will have problems; upgrading would be a really good plan.



All Solaris versions



      We have a report that says starting with Solaris 2.6 we should leave
      dosynctodr alone.
      Here is the report.


Proper operation of ntp under Solaris may require setting the kernel
variable dosynctodr to zero (meaning "do not synchronize the clock
to the hardware time-of-day clock").  This can be done with the
tickadj utility:


tickadj -s


If you prefer, it can also be done with the native Solaris kernel debugger:


echo dosynctodr/W0 | adb -k -w /dev/ksyms /dev/mem




Or, it can also be set by adding a line to /etc/system:


set dosynctodr = 0




Instead of the tick kernel variable, which many operating
systems use to control microseconds added to the system time every
clock tick (c.f. Dealing
with Frequency Tolerance Violations), Solaris has the variables
nsec_per_tick and usec_per_tick.


nsec_per_tick and usec_per_tick control the number of
nanoseconds and microseconds, respectively, added to the system clock
each clock interrupt. Enterprising souls may set these based on
information collected by ntpd in the /etc/ntp.drift file
to correct for individual hardware variations.


On UltraSPARC systems, nsec_per_tick and usec_per_tick
are ignored in favor of the cpu_tick_freq variable, which
should be automatically be determined by the PROM in an accurate
fashion.


In general, the same ntp binaries should not be used across multiple
operating system releases. There is enough variation in the core operating
system support for timekeeping that a rebuild of ntpd for the idiosyncracies
of your specific operating system version is advisable.


It is recommended that ntp be started via a script like this one, installed in
/etc/init.d/ntpd with a symbol link from
/etc/rc2.d/S99ntpd.


Solaris 2.6



Solaris 2.6 adds support for kernel PLL timekeeping, but breaks this
support in such a fashion that using it worse than not. This is  SUN Bug ID 4095849, and it is not yet
fixed as of June 1998.



Solaris 2.5 and 2.5.1



On UltraSPARC systems, calculation of cpu_tick_freq is broken
such that values that are off by significant amounts may be used
instead. This unfortunately means that ntpd may have severe problems
keeping synchronization. This is  SUN Bug ID
4023118. Bryan Cantrill  of Sun
posted patchfreq, a workaround script,
to comp.protocols.time.ntp in March of 1997.





OLD DATA

I can't vouch for the accuracy the information below this
rule. It may be significantly dated or incorrect.





Solaris 2.2



Solaris 2.2 and later contain completely re-written clock code to
provide high resolution microsecond timers. A benefit of the
re-written clock code is that adjtime does not round off its
adjustments, so ntp does not have to compensate for this
rounding. Under Solaris 2.2 and later, ntp #define's
ADJTIME_IS_ACCURATE, and does not look for the tickadj
kernel variable.



Solaris 2.1

(This originally written by William L. Jones <jones@chpc.utexas.edu>)


Solaris 2.1 contains fairly traditional clock code, with tick
and tickadj.


Since settimeofday under Solaris 2.1 only sets the seconds part of timeval
care must be used in starting xntpd.  I suggest the following start
up script:


tickadj -s -a 1000

ntpdate -v server1 server2

sleep 20

ntpdate -v server1 server2

sleep 20

tickadj -a 200

xntpd



The first tickadj turns of the time of day clock and sets the tick
adjust value to 1 millisecond.  This will insure that an adjtime value
of at most 2 seconds will complete in 20 seconds.


The first ntpdate will set the time to within two seconds 
using settimeofday or it will adjust time using adjtime.


The first sleep insures the adjtime has completed for the first ntpdate.


The second ntpdate will use adjtime to set the time of day since the
clock should be within 2 seconds of the correct time.


The second tickadj set the tick adjust system value to 5 microseconds.


The second sleeps insure that adjtime will complete before starting 
the next xntpd.


I tried running with a tickadj of 5 microseconds with out much success.
200 microseconds seems to work well.

    Older SCO Unix versions
    
		
    NTP 4.0.x does not run on SCO Unix prior to version 3.2.5.0.0. If you need NTP on an older SCO Unix system and don't mind to modify your kernel, use 3.5.91 which has patches for SCO Unix 3.2.4.x. Apply the kernel modifications as described in XNTP on SCO 3.2.4.2.
    
		
    Compiling NTP
    
		
    Delete the old SCO supplied NTP programs using the "custom" utility. Run the NTP configure program with CFLAGS="-b elf -K processor-type" for best results.
    
		
    Running NTP
    
		
    Run "tickadj -As" after every reboot to set the variables "clock_drift" and "track_rtc" to the right values.
    
		
    Run "ntpd" with a high negative nice-value, i.e. "nice --19 ntpd" for best results.

hardware running DEC OSF/1.  All "long" and "u_long" declarations and
casts in the code were changed to "LONG" and "U_LONG" and a new header
file (include/ntp_types.h) was added.  The new header file defines
LONG as int and U_LONG as u_int for the Alpha hardware and as long
and u_long for anything else.  A couple of #ifs where changed in
ntpq and xntpdc to get the result of a signal defined correctly.  The
Config.decosf1 file built the programs here with no problems.

I don't have a radio clock here, so none of that code has been tested.
I have run xntpd, xntpdc, xntpres, ntpq, ntpdate, and tickadj under
DEC OSF/1 v1.2-2 (BL10).

Support for NTP Version 2 is included with the current OSF/1 release. If
you are upgrading to NTP Version 3 with this distribution, you should not
use the xntpd or ntpq programs that come with the OSF/1 release. The
older programs should be replaced by the newer programs of the same name,
either in situ or via a link to a tranquil spot like /usr/local/bin. The
make install script in the this distribution don't work due to a silly
install program incompatibility, so you will need to copy the programs by
hand.

Don't use the setup utility to install or configure the xntpd installation,
as it will cheerfully clobber your painstakingly crafted ntp.conf program.
However, assuming you put this file in /etc/ntp.conf, you can use the
/sbin/init.d/xntpd script to start and stop the daemon.

This distribution compiles with nominal mumur with the stock cc compiler
that comes with OSF/1.

 Category: kernel
 Subcategory: syscall
 State: evaluated
 Synopsis: time_constant value >6 with PLL in use leads to integer divide
           zero trap panic
 Description:
If the time_constant parameter is 7 or higher, and the phase-lock looping model
is in use, the system will take a "integer divide zero trap" panic in
the clock routine as soon as the time_offset becomes non-zero.

time_constant defaults to 0.  The only place it is set is in the ntp_adjtime
system call, from the 'constant' element of the timex structure argument.

 Work around:
Never set the constant element of the timex structure passed to ntp_adjtime to
a value larger than 6.

1. Use Sun's version of NTP software instead of PD version. This problem
is not seen with Sun's NTP version (which is mostly eqivalent to PD NTP 3.4
plus some Sun's local functionality futures).

2. Workaround for the public domain NTP version  ONLY:
 =====================================================
The workaround for public domain NTP version is to disable the
KERNEL_PLL from the NTP code. This way ntp_Adjtime() system call is
totally bypassed without sacrificing any of the functionality of the
NTP. The only hit you might see is the way  kernel precision timminig
is done without the PLL algorithm in the kernel.

    The easiest way to disable ntp_adjtime option is(without changing
    any makefiles or other config files) to disable the KERNEL_PLL
    value in the ./config.h file.

After doing a ./configure for probing for all the necessary tools(compilers,
os version, libraries),  please comment out KERNEL_PLL macro in
the ./config.h  file.  This will disable the KERNEL_PLL part of the source
code and the newly obtained xntpd is just similar to the old one but it
does not use ntp_adjtime() system call. This prevents it from panic'ng
the kernel.

/*#define KERNEL_PLL 1*/

I complied a new xntpd binary this way and it does nothave any ntp_adjtime()
related stuff.

--------------------------

The SGI value for HZ is 100 under Irix 4, with the system clock running
in nominal mode (ftimer off), so the value for tick is 10000 usec.
Tickadj is a bit more tricky because of the behaviour of adjtime(),
which seems to try to perform the correction over 100-200 seconds, with
a rate limit of 0.04 secs/sec for large corrections.  Corrections of
less than 0.017 seconds generally complete in less than a second,
however.

Some measured rates are as follows:

	Delta       Rate (sec/sec)

	> 1		0.04
	0.75		0.04
	0.6		0.004
	0.5		0.004
	0.4		0.0026
	0.3		0.0026
	0.2		0.0013
	0.1		0.0015
	0.05		0.0015
	0.02		0.0003
	0.01		0.015
Strange.  Anyway, since adjtime will complete adjustments of less than
17msec in less than a second, whether the fast clock is on or off, I
have used a value of 150usec/tick for the tickadj value.

Fast clock:
-----------

I get smoother timekeeping if I turn on the fast clock, thereby making
the clock tick at 1kHz rather than 100Hz.  With the fast clock off, I
see a sawtooth clock offset with an amplitude of 5msec.  With it on,
the amplitude drops to 0.5msec (surprise!).  This may be a consequence
of having a local reference clock which spits out the time at exactly
one-second intervals - I am probably seeing sampling aliasing between
that and the machine clock.  This may all be irrelevant for machines
without a local reference clock.  Fiddling with the fast clock doesn't
seem to compromise the above choices for tick and tickadj.

I use the "ftimer" program to switch the fast clock on when the system
goes into multiuser mode, but you can set the "fastclock" flag in
/usr/sysgen/master.d/kernel to have it on by default.  See ftimer(1).

timetrim:
---------

Irix has a kernel variable called timetrim which adjusts the system
time increment, effectively trimming the clock frequency.  Xntpd could
use this rather than adjtime() to do it's frequency trimming, but I
haven't the time to explore this.  There is a utility program,
"timetrim", in the util directory which allows manipulation of the
timetrim value in both SGI and xntpd native units.  You can fiddle with
default timetrim value in /usr/sysgen/master.d/kernel, but I think
that's ugly.  I just use xntpd to figure out the right value for
timetrim for a particular CPU and then set it using "timetrim" when
going to multiuser mode.

Serial I/O latency:
-------------------

If you use a local clock on an RS-232 line, look into the kernel
configuration stuff with regard to improving the input latency (check
out /usr/sysgen/master.d/[sduart|cdsio]).  I have a Kinemetrics OM-DC
hooked onto /dev/ttyd2 (the second CPU board RS-232 port) on an SGI
Crimson, and setting the duart_rsrv_duration flag to 0 improves things
a bit.

 Category: kernel
 Subcategory: other
 State: integrated
 Synopsis: sun4u doesn't keep accurate time
 Description:

[ bmc, 12/20/96 ]

The clock on a sun4u drifts unacceptably.  On a typical 143 mHz Ultra,
the clock took 1.0001350 seconds to count 1 second.  While this may seem
trivial, it adds up quickly.  In this case, the TOD chip will have to
pull the clock forward by 2 seconds every 4 hours and 7 minutes.
This drift rate is so high, that the clock is close to being too broken
for NTP to guarantee correctness (in order for NTP's mechanism to work,
it must be assured that the local clock drifts no more than 20 ms in 64
seconds;  this particular 143 mHz Ultra will drift by nearly 9 ms in that
period).  This problem has been reproduced on virtually all sun4u
classes.

The fundamental problem lies in the kernel's perception of ticks per
second.  The PROM is responsible for determining this figure exactly,
and the kernel extracts it into the variable cpu_tick_freq.  On sun4u's,
this number is disconcertingly round:  143000000, 167000000, 248000000,
etc.  Indeed, a simple experiment revealed that these numbers were
quite far from the actual ticks per second.  Typical was the 143 mHz
Ultra which was discovered to tick around 142,980,806 (+/- 10) times
per second.

        vxWorks Port of NTP
		
	


    
        
    VxWorks port of NTP
    
        
    Creating a port for vxWorks posed some problems. This port may help as a starting point for similar ports to real-time OS's and other embeddable kernels, particularly where main() is not allowed, and where the configure scripts need to be altered.
    
        
    Configuration issues
    
        
    I decided to do as little invasive surgery as possible on the NTP code, so I brought the vxWorks header tree in line with the standard Unix tree. The following changes were needed, as a side effect these changes will allow for easy porting of other autoconfigure enabled code.
    
        
    Where I have 386 you will need to put in your target type. The vxWorks tree entry point is /usr/wind. If these are the same for your system, you should be able to cut and paste the changes.
    
        
    WARNING: Check you are not overwriting files, before entering the following: there should be no conflict, but check first...
    
		
                export CC="cc386 -nostdlib -m486 -DCPU=I80486 -I/usr/wind/target/h"
            export RANLIB=ranlib386
            export AR=ar386
            export VX_KERNEL=/usr/wind/target/config/ims_std_bsp/vxWorks

            ln -s ../time.h
            ln -s socket.h sockio.h
            ln -s ../selectLib.h select.h
            ln -s ../timers.h
            touch file.h param.h resource.h utsname.h var.h ../netdb.h ../a.out.h ../termios.h
         echo " ******ADD #include \"sys/times.h\" to sys/time.h "
            
    
		The configure script must be changed in the following way to get the linking tests to work, once in the correct directory issue the following commands:
		
		
          sed -e 's%main.*()%vxmain()%' configure > configure.vxnew
            mv configure.vxnew configure
            chmod 755 configure
      
    
		
    The new version 4 of NTP requires some maths functions so it links in the maths library (-lm) in the ./ntpd/Makefile.am file change the line ntpd_LDADD = $(LDADD) -lm by removing the "-lm".
    
		 
    >You are now ready to compile
		
    The ./configure.in file needed to be altered to allow for a host-target configuration to take place.
    
		
      
            
    • The define SYS_VXWORKS was added to the compilation flags.
            
    • Little endianess is set if the target is of type iX86.
            
    • The size of char, integer, long values are all set. If Wind River ever changes these values they will need to be updated.
            
    • clock_settime() is defined to be used for setting the clock.
            
    • The Linking flags have -r added to allow for relinking into the vxWorks kernel
        
    
        
    Unfortunately I have had to make use of the ./include/ntp_machine.h file to add in the checks that would have been checked at linking stage by autoconf, a better method should be devised.
    
        
      
            
    • There is now a NO_MAIN_ALLOWED define that simulates command line args, this allows the use of the normal startup sysntax.
            
    • POSIX timers have been added.
            
    • Structures normally found in netdb.h have been added with, the corresponding code is in ./libntp/machines.c. Where possible the defines for these have been kept non-vxWorks specific.
        
    
        
    Unfortunately there are still quite a few SYS_VXWORKS type defines in the source, but I have eliminated as many as possible. You have the choice of using the usrtime.a library avaliable from the vxworks archives or forgoing adjtime() and using the clock_[get|set]time(). The ./include/ntp_machine.h file clearly marks how to do this.
    
        
    Compilation issues
    
        
    You will need autoconf and automake ... available free from the gnu archives worldwide.
    
        
    The variable arch is the target architecture (e.g. i486)
    
        
                mkdir A.vxworks)
            cd A.vxworks
            ../configure --target=arch-wrs-vxworks
            make
       
    
        
    Options I normally use are the --disable-all-clocks --enable-LOCAL-CLOCK flags. The program should proceed to compile without problem. The daemon ntpd, ntpdate, ntptrace, ntpdc, ntpq programs and of course the libraries are all fully ported. The other utilities are not, but they should be easy to port.
    
        
    Running the software
    
        
    Load in the various files, call them in the normal vxWorks function type manner. Here are some examples. Refer to the man pages for further information.

----------------------------------------

NTP was first ported to MPE several years ago, but those diffs were never
submitted back to the official NTP distribution.  For more information about
that deprecated port, please see http://www.bixby.org/mark/xntpix.html.

NTP was re-ported to MPE in May 2001.  What follows are hints learned from
working with NTP 4.0.99k23.  For additional information about NTP on MPE,
please see http://jazz.external.hp.com/src/hp_freeware/ntp/.

MPE lacks the clock-related APIs expected by NTP, so adjtime(), gettimeofday(),
and settimeofday() all had to be implemented from scratch by calling
privileged, undocumented internal OS functions.

Unfortunately the implementation of adjtime() has exposed a sub-second accuracy
bug when slewing the system time.  This bug is documented in SR 5003462838, and
exists on all current versions of MPE.  It has not been fixed at the time of
this writing.  The adjtime() code may possibly need to be altered if/when this
bug is fixed.

This bug has a side-effect whereby the ntpd daemon will screw up the hardware
PDC clock time by many minutes if used for continuous clock adjustments or in
the one-time -q mode.  But note that you can safely run ntpd in order to become
a time server if you include "disable ntp" in the ntp.conf configuration file.

The one-time clock adjustment functionality of ntpdate and ntp_timeset is not
affected by this bug side-effect.  You can safely use these commands to alter
your system time with reasonable accuracy.

The only reference clock that has been tested on MPE is the local clock.  So
building NTP with --disable-all-clocks --enable-LOCAL_CLOCK is strongly
recommended.

NTP makes use of Privileged Mode (PM) capability in order to bind to the NTP
network port (123) and to access the low-level clock functions.

NTP was ported using the gcc compiler.  Attempting to use the HP C/iX compiler
is not recommended and has not been tested.

Please note that NTP is not an HP product and is NOT supported by HP.  The best
place for asking MPE-specific questions about NTP is the HP3000-L mailing list
at http://raven.utc.edu/Archives/hp3000-l.html or the associated Usenet
newsgroup of comp.sys.hp.mpe.

This file hopefully describes the whatever and however of how to get xntp
running on hpux 7.0 and later s300. s400, s700, and s800.  

First off,  all the standard disclaimers hold here ... HP doesn't have anthing
to do with this stuff.  I fool with it in my spare time because we use it and
because I like to.  We just happen to have a lot of HP machines around here :-)
Xntpd has been in use here for several years and has a fair amount of mileage
on various HP platforms within the company.  I can't really guarantee bug fixes
but I'd certainly like to hear about bugs and I won't hestitate to look at
any fixes sent to me.  

Now lets talk OS.  If you don't have 7.0 or later, pretty much hang it up now.
This stuff has run here on pretty much everything from 8.0 upward on s300, 
s700, and s800.  It is known to run on 7.0 s300/s400 but all reports are 
from the field and not my personal experience.

If you are lucky enough to have a s300 or s400 with 9.03, then you no longer
have to worry about adjtimed as HP-UX now has adjtime(2).  The rest of you
will have to wait on 10.0 which will have adjtime(2) and a supported though
a bit older version of xntpd.

Next, let me explain a bit about how this stuff works on HP-UX's that do not
have adjtime(2).  The directory adjtime contains libadjtime.a and the adjtimed
daemon.  Instead of the adjtime(2) system call, we use a library routine to
talk to adjtimed thru message queues.  Adjtimed munges into /dev/kmem and
causes the clock to skew properly as needed.  PLEASE NOTE that the adjtime
code provided here is NOT a general replacement for adjtime(2) ... use of
this adjtime(3)/adjtimed(8) other than with xntpd may yield very odd results.

What to do to get this stuff running ?

    * If you are running an OS less than 10.0 or do not have a s300/s400 
      with 9.03 or better
	-> cd machines
	-> vi hpux
	-> (change -DSYS_HPUX=? to match whatever you are running [7,8,9])
	-> cd ..

    * Say "make makeconfig"

    * Say "make", sit back for a few minutes.

    * cd authstuff
	* Say "./authcert < certdata" and check the output.  Every line should
	  end with "OK" ... if not, we got trouble.
	* Now try "./authspeed auth.samplekeys".  What we want to 
	  remember here is the "authentication delay in CPU time" 
	* cd ..

    * Say "make install"

    * I'd suggest reading the xntp docs about now :-) ... seriously !!

    * One thing I have added to this version of xntpd is a way to select 
      config files if you are sharing /usr/local thru NFS or whatever.  
      If the file /usr/local/etc/xntp.conf happens to be a directory, the 
      files in that directory are searched until a match is found.  The 
      rules for a match are:

	1. Our hostname
	2. default. (as in default.375 or default.850)
	3. default

    * Ok, make sure adjtimed is running (just start it up for now with
      "/usr/local/etc/adjtimed").  Using -z as an option will get you 
      a usage message.

    * Now start up xntpd and watch it work.

    * Make sure that adjtimed gets started at boot right before xntpd.
      We do this in /etc/netbsdsrc.  They must both run as root !!

Possible problems ?

    * On some 320's and 835's we have had to run adjtimed with "-p 45" or
      so to get rid of syslog messages about "last adjust did not finish".

    * At 9.0, there is a problem with DIAGMON (patch available from the
      response center) which causes it to delete the message queue that
      adjtimed/xntpd use to communicate. (see next note for result)

    * Xntpd has been known to get really ticked off when adjtime() fails
      which is usually only while running the emulation code on HP-UX.
      When it gets mad, it usually jumps the clock into never never land.
      Possible reasons for this are adjtimed being killed or just never
      started or adjtimed being completely swapped out on a really busy
      machine (newer adjtimed try to lock themselves in memory to prevent
      this one).

Dave,
   After reading the hpux hints file, I realized I didn't install or 
start adjtimed.  In the course of doing this, I discovered that:

--> $(TOP) is not defined in adjtime/Makefile, so "make install" can't
    find the install.sh script.

--> "make install" from the main Makefile never goes into the adjtime
    directory, so I added the following two lines into the install
    target of the main Makefile:

    @echo installing from adjtime
    @cd adjtime && $(MAKE) $(MFLAGS) MFLAGS="$(MFLAGS)" MAKE="$(MAKE)" install

This twiddle may not be right for all systems, but it got adjtimed
installed for me.

   You might also want to add to the hpux hints file that one way to
fire things up at boot time is to add the following lines to the localrc
function of /etc/rc:

    #---daemons for Network Time Protocol (version 3.4s)
    #---note that adjtimed is only needed for HP-UX 9.X, not 10.0
    #---adjtimed must be running or xntpd won't work right...
    if [ -x /usr/local/bin/adjtimed ]; then
        /usr/local/bin/adjtimed -r & echo -n ' adjtimed'
        if [ -x /usr/local/bin/xntpd ]; then
            /usr/local/bin/xntpd &    echo -n ' xntpd'
        fi
    fi

I discovered that the "-r" option of adjtimed is needed to clear out any
trash from a previous execution of it.  Otherwise adjtimed quietly dies
and leaves xntpd in the lurch...

Thanks for the help.

Included in this distribution of XNTP is a configuration file suitable
for use with BSDI's BSD/OS 1.1 (formerly BSD/386 1.1).  On this system,
the "cc" command is GCC 1.4x rather than PCC or GCC 2.x.  It is imperative
that "cc" be used since it predefines the symbol __bsdi__; if you want to
use another compiler you will need to add -D__bsdi__ to catch the various
#ifdef's required for this system.

The Kinemetrics/Truetime GPS-TM/TMD driver is known to work on this system.
The GPS-805 and GOES should also work fine.  Hell, they should all work fine
but it's hard to test very many locally.

Due to BNR2's strict interpretation of POSIX and XNTP's use of SIGIO, BSD/OS
can only handle one refclock per daemon.  We're working this out with the
system architects.

The config file is machine/bsdi, and the following steps should be all that
are required to install and use the bits.

Note that you will need GNU sed; the version supplied with BSD/OS 1.1 loops
endlessly during "make refconf".  Likewise you should get GNU make, which
the instructions below assume that you have put in /usr/local/bin/gnumake.

To build the software:

	rm -f Config.local
	gnumake refconf
	gnumake MAKE=gnumake

To install the software:

	gnumake install

	This will place all of the executables in /usr/local/etc.  The config
	file is expected to be /usr/local/etc/xntp.conf and the key file for
	the optional authentication is /etc/ntp.keys.

	Craft a config file and a key file, and put them in the right places.
	There is information on how to do this elsewhere in the documentation,
	the only thing I'll mention is that I put the drift file in 
	/var/log/ntp.drift, and the authdelay on my 486DX/50 system is 
	0.000064.  Your mileage will vary, learn to use the authspeed tools
	if you're going to authenticate.
	
	In the file /etc/rc.local, make sure that the invocation of ntpd is
	commented out, and add an invocation of xntpd.  Here's what I'm using:

		echo -n 'starting local daemons:'

		if [ -f /etc/ntp.keys -a -f /usr/local/etc/xntp.conf ]; then
		    echo -n ' xntpd';           /usr/local/etc/xntpd
		fi

		#XXX# echo -n ' ntpd';          /usr/libexec/ntpd -t

At this point, you should be good to go.  Try running /usr/local/etc/xntpd and
using ntpq or xntpdc to see if things are working, then pay attention the next
time you reboot to make sure that xntpd is being invoked, and use ntpq or
xntpdc again to make sure all is well.  

Enjoy!

This version operates in much the same manner as Version 2 with the
following changes and additions:

1.   The protocol machinery operates in conformance with the RFC1305 NTP
     Version 3 specification. The most visible characteristic of this
     version is that the poll intervals for all polls, even selected
     ones, is significantly increased. This is especially desirable when
     serving a large client population. This implementation supports
     previous versions as non-configured peers; for version-2 configured
     peers a "version 2" keyword should be included on the "peer" line.

2.   The configuration file has a new keyword: statfile , where
      is the name of a statistics file." When present, each clock
     update generates an entry of the form:

      .     

     where  is the modified Julian day, . is the time of
     day,  is the peer address and  is the peer status.
     The ,  and  are the measured offset, delay and
     dispersion, respectively, of the peer clock relative to the local
     clock. About once per day the current file is closed and a new one
     created with names ., where  starts at one and
     increments for each new generation.

3.   A number of additional platforms are supported. See ./Config file
     for details.

4.   A driver for the TrueTime 468DC GOES Synchronized Clock is
     included. This driver (refclock_goes.c) should also work for other
     TrueTime radio clocks, since all use the same format.

5.   A replacement driver for the Spectracom 8170 WWVB Synchronized
     Clock is included. This driver (refclock_wwvb.c) (a) does not
     require a 1-pulse-per-second signal, (b) supports both format 0
     (original 8170) and format 2 (Netclock/2 and upgraded 8170), (c)
     can be connected to more than one computer and (d) automatically
     compensates for all serial baud rates.

6.   A driver for the German time/frequency station DCF77 is included.
     This requires a special STREAMS module.

7.   In Version 2 special line-discipline modules were required for the
     CHU and WWVB drivers. This code continues to work in Version 3,
     although it is no longer needed for the WWVB driver. However, this
     code does not work under STREAMS, as used in SunOS 4.1.1.
     Equivalent STREAMS modules are supplied with Version 3.

8.   Support for an external 1-pulse-per-second (pps) signal is
     provided. The signal is connected to a serial port (see
     xntpd/ntp_loopfilter.c for details). When present the leading edge
     of the pulse establishes the on-time epoch within an interval
     established by the selected radio clock or other NTP time server.
     Use of the pps is indicated when the tattletale displayed by ntpq
     changes from "*" to "o".

9.   The clock-selection and poll-update procedures have been modified
     slightly in order to achieve better performance on high speed LANs
     with compromise in performance on typical WANs.

10.  In order to comply with U.S. Commerce Department regulations, the DES
     encryption routine lib/authdes.c cannot be exported. For exportable
     versions of this distribution a DES-encrypted version of this routine
     lib/authdes.c.des is included along with an unencrypted version
     lib/authdes.c.export, which allows normal operation, but without the
     NTP authentication feature. Further information is available in the
     lib/authdes.c.export file.

11.  As an alternative to the DES-based authentication mechanism, an
     implementation of the RSA Message Digest 5 algorithm is provided.
     (see applicable copyright information in the library files).

12.  A driver for the Magnavox MX4200 GPS clock.

13.  A STREAMS module which captures carrier-detect data-lead transitions to
     connect a precision source of 1-pps, yet avoid the ugly overhead in the
     usual STREAMS processing. See the ppsclock subdirectory.

14.  Support for the Apple A/UX operating system and enhanced support for the
     Hewlet-Packard HP/UX operating system. See the various README and Config
     files for further information. 

See the COPYRIGHT file for authors and copyright information. Note that some
modules in this distribution contain copyright information that supersedes
the copyright information in that file.

Bugs and notes

A bug in the original tty_clk_STREAMS.c module has been fixed.

The poll-interval randomization feature of poll_update (in
xntpd/ntp_proto.c) has been extended to apply when the poll interval is
increased, as well as reduced. This spreads the update messages in time
and helps avoid unpleasant bursts of messages.

In the clock_select algorithm the peers selected for combining are
limited to those survivors at the lowest stratum, not the entire list.
This helps avoid whiplash when large numbers of peers are at the same
stratum.

The number formerly displayed by ntpq as "compliance" is now the time
constant of integration.

The DNS resolver xntpd/ntp_intres.c is now integrated into xntpd, making
configuration of multiple hosts easier.

System and peer event are now written to the system log at priority
LOG_INFO.

The leap-second code was fixed to avoid broadcasting leap warnings on
all except the last day of June and December.

        NTP on Windows NT
		
	
    
        
    NTP 4.x for Windows NT
    

        
    Introduction
    
		
    The NTP 4 distribution runs as service on Windows Vista, Windows NT 4.0, Windows 2000, Windows XP, Windows .NET Server 2003. It will NOT run on Windows 95, 98, ME, etc. The binaries work on multi-processor systems. This port has not been tested on the Alpha platform. This release now uses OpenSSL for authentication. IPv6 is not implemented yet for Win32 platforms. A ready-to-run install distribution is available from Meinberg at http://www.meinberg.de/english/sw/ntp.htm.
    
		
    Users should note that the stock Windows client sends requests as mode-1 packets, which can have unintended consequences and create a security risk. The client should send requests as mode-3 (client) packets, which conform to the protocol specification. The issues and resolution are described in Microsoft KB 875424. A less desirable alternative that avoids changing registry keys is to use the --with-wintime option when building the executable.
    
		
    Authentication Keys
    
		
    With this release ntp-keygen is supported. See the  ntp keygen documentation for details on how to use ntp-keygen.
    
        
    ntpd can now use the generated keys in the same way as on Unix platforms. Please refer to the Authentication Options for details on how to use these.
    
        
    NOTE: ntpd and ntp-keygen both use OpenSSL which requires a random
        character file called .rnd by default. Both of these programs will automatically generate this file if they are not found. The programs will look for an environmental variable called RANDFILE and use that for the name of the random character file if the variable exists. If it does not exist it will look for an environmental variable called HOME and use that directory to search for a file called .rnd in that directory. Finally, if neither RANDFILE nor HOME exists it will look in C:\ for a .rnd file. In each case it will search for and create the file if the environmental variable exists or in the C:\ directory if it doesn't.
    
        
    Note that ntpd normally runs as a service so that the only way that it will have either RANDFILE or HOME defined is if it is a System environmental variable or if the service is run under a specific account name and that account has one of those variables defined. Otherwise it will use the file c:\.rnd. This was done so that OpenSSL will work normally on Win32 systems. This obviates the need to ship the OpenSSL.exe file and explain how to generate the .rnd file. A future version may change this behavior.
    
        
    Refer to Compiling Requirements and Instructions for how to compile the program.
    
        
    Reference Clocks
    
        
    Reference clock support under Windows NT is tricky because the IO functions are so much different. Some of the clock types have been built into the ntpd executable and should work but have not been tested by the ntp project. If you have a clock that runs on Win32 and the driver is there but not implemented on Win32 you will have make the required configuration changes in config.h and then build ntpd from source and test it. The following reference clock is known to work and is supported by Windows NT: Type 1 Undisciplined Local Clock (LOCAL)
    
        
    Functions Supported
    
        
    All NTP functions are supported with some constraints. See the TODO list below. Note that the ntptrace executable is not supported and you should use the PERL script version instead.
    
        
    Accuracy
    
        
    Greg Brackley has implemented a fantastic interpolation scheme that improves the precision of the NTP clock using a realtime thread (is that poetic or what!) which captures a tick count from the 8253 counter after each OS tick. The count is used to interpolate the time between operating system ticks.
    
        
    On a typical 200+ MHz system NTP achieves a precision of about 5 microseconds and synchronizes the clock to +/-500 microseconds using the Trimble Palisade as UTC reference. This allows distributed applications to use the 10 milliseconds ticks available to them with high confidence.
    
        
    Binaries
    
        
    Recent InstallShield based executable versions of NTP for Windows NT (intel) are available from:
    
        
        
    ToDo
    
        
    These tasks are in no particular order of priority.
    
        
      
            
    • Create a proper install/uninstall program
            
    • Add sntp to the list of supported programs
            
    • Add support for Visual C++ 7.0 or later (.NET)
            
    • Add IPv6 support
            
    • See if precision can be improved by using CPU cycle counter for tick interpolation.
            
    • Make precision time available to applications using NTP_GETTIME API
        
    
        
    Compiling Requirements
    
        
      
            
    • Windows NT 4.0 Windows 2000, Windows XP,Windows Vista or Windows.NET Server 2003
            
    • Microsoft Visual C++ 2008 EE or Visual C++ 2010 EE
            
    • Some way of uncompressing and untarring the gzipped tar file.
            
    • OpenSSL must be built on the box before building NTP. Additional steps would
            be required to not use OpenSSL.
        
    • Microsoft Visual C++ redistributables
    
        Compiling Instructions
        
      
            
    1. Install Micosoft Visual C++ redistributables
            
    2. Install OpenSSL full installer for Windows. Add the following to your system environment variables in the control panel (adjusting paths as appropriate to point to the directory containing only an openssl subdirectory, for OPENSSL_INC, and to the directory containing openssl .lib files for OPENSSL_LIB:

      • 	OPENSSL_INC=C:\OpenSSL\include

      • 	OPENSSL_LIB=C:\OpenSSL\lib
      
            
    3. Unpack the NTP-4.x.tar.gz using utilities such as WinZip or WinRar.
            
    4. Run Microsoft Visual C++ 2008 EE.  On Windows Vista and later, Run as Administrator.
            
    5. Open the ports\winnt\vs2008\ntp.sln solution file
            
    6. Batch build all projects (Build menu, Batch Build..., select all, build).
            
    7. The built binaries can be found in the ports\winnt\v2008\bin\ directory.
            
    8. If you are shipping binaries in a kit it is strongly recommended that you ship this file (winnt.html) along with the binaries.
        
    
        
    Configuration File
    
        
    The default NTP configuration file path is %SystemRoot%\system32\drivers\etc\. (%SystemRoot% is an environmental variable that can be determined by typing "set" at the "Command Prompt" or from the "System" icon in the "Control Panel").
    
        
    Refer to your system environment and create your ntp.conf file in the directory corresponding to your system  installation. The older <WINDIR>\ntp.conf is still supported but you will get a log entry reporting that the first file wasn't found.
        
    Installation Instructions
    
        
    The instsrv program in the instsrv subdirectory of the distribution can be used to install 'ntpd' as a service and start automatically at boot time. Instsrv is automatically compiled with the rest of the distribution if you followed the steps above.
    
        
      
            
    1. Start a command prompt and enter "instsrv.exe <pathname_for_ntpd.exe>"
            
    2. Clicking on the "Services" icon in the "Control Panel" will display the list of currently installed services in a dialog box. The NetworkTimeProtocol service should show up in this list. Select it in the list and hit the "Start" button in the dialog box. The NTP service should start.
            
    3. You can also stop and start the service by typing net start|stop NetworkTimeProtocol at the DOS prompt.
            
    4. View the event log by clicking on the "Event Viewer" icon in the "Administrative Tools" group, there should be several successful startup messages from NTP. NTP will keep running and restart automatically when the machine is rebooted.
        
    
        
    You can change the start mode (automatic/manual) and other startup parameters corresponding to the NTP service in the "Services" dialog box if you wish.
    
        
    Removing NTP
    
        
    You can also use instsrv to delete the NTP service by entering: >"instsrv.exe remove"
        
    Command Line Parameters and Registry Entries
    
        
    Unlike the Unix environment, there is no clean way to run 'ntpdate' and reset the clock before starting 'ntpd' at boot time. NTP will step the clock up to 1000 seconds by default. While there is no reason that the system clock should be that much off during bootup if ntpd was running before, you may wish to override this default and/or pass other command line directives.
        
    Use the registry editor to edit the value for the ntpd executable under LocalMachine\System\CurrentControlSet\Services\NTP.
    
        
    Add the -g option to the ImagePath key, behind "%INSTALLDIR>\ntpd.exe". This will force NTP to accept large time errors (including 1.1.1980 00:00)

    by Danny Mayer (mayer@ntp.org>)
    
        
    Significant Changes:
    
        
    This latest release of NTP constitutes a major upgrade to its ability to build and run on Windows platforms and should now build and run cleanly. More importantly it is now able to support all authentication in the same way as Unix boxes. This does require the usage of OpenSSL which is now a prerequisite for build on Windows. ntp-keygen is now supported and builds on Win32 platforms.

    ignificant Changes:
    
        
      
            
    • Fixed I/O problem delaying packet responses which resulted in no-replys to NTPQ and others.
            
    • The default configuration file path is <WINDIR>\system32\drivers\etc\ntp.conf. The old <WINDIR>\ntp.conf is still supported but you will get a log entry reporting that the first file wasn't found. The NTP 3.x legacy ntp.ini file is no longer supported.
        
    
        
    Known Problems / TODO:

    This version corrects problems with building the XNTPversion 3.5-86 distribution under Windows NT. The following files were modified:
    
      	
      
            
    • blddbg.bat
            
    • bldrel.bat
            
    • include\ntp_machine.h
            
    • xntpd\ntp_unixclock.c
            
    • xntpd\ntp_refclock.c
            
    • scripts\wininstall\build.bat
            
    • scripts\wininstall\setup.rul
            
    • scripts\wininstall\readme.nt
            
    • scripts\wininstall\distrib\ntpog.wri
            
    • html\hints\winnt (this file)
        
    
        
    In order to build the entire Windows NT distribution you           need to modify the file scripts\wininstall\build.bat with the installation directory of the InstallShield software.  Then, simply type "bldrel" for non-debug or "blddbg" for debug executables.

    This set of changes fixes all known bugs, and it includes
    
        several major enhancements. Many changes have been made both to the build environment as well as the code.  There is no longer an ntp.mak file, instead there is a buildntall.bat file that will build the entire    release in one shot. The batch file requires Perl.  Perl is easily available from the NT Resource Kit or on the Net.
    
        
    The multiple interface support was adapted from Larry Kahn's       work on the BIND NT port.  I have not been able to test it,      adequately as I only have NT servers with one network interfaces on which to test.
    
        
    Enhancements:
    
        
      
            
    • Event Logging now works correctly.
            
    • Version numbers now work (requires Perl during build)
            
    • Support for multiple network interface cards (untested)
            
    • NTP.CONF now default, but supports ntp.ini if not found
            
    • Installation procedure automated.
            
    • All paths now allow environment variables such as %windir%
        
    
        
    Bug fixes
    
        
      
            
    • INSTSRV replaced, works correctly
            
    • Cleaned up many warnings
            
    • Corrected use of an uninitialized variable in XNTPD
            
    • Fixed ntpdate -b option
            
    • Fixed ntpdate to accept names as well as IP addresses
            (Winsock WSAStartup was called after a gethostbyname())
            
    • Fixed problem with "longjmp" in xntpdc/ntpdc.c that  caused a software exception on doing a Control-C in xntpdc. A Cntrl-C now terminates the program.
        
    
        
    See below for more detail
    
        
    Note: SIGINT is not supported for any Win32 application including; Windows NT and Windows 95. When a CTRL+C interrupt occurs, Win32 operating systems generate a new thread to specifically handle that interrupt. This can cause a single-thread application such as UNIX, to become multithreaded, resulting in unexpected behavior.
    
        
    Possible enhancements and things left to do:
    
        
      
            
    • Reference clock drivers for NT (at least Local Clock support)
            
    • Control Panel Applet
            
    • InstallShield based installation, like NT BIND has
            
    • Integration with NT Performance Monitor
            
    • SNMP integration
            
    • Fully test multiple interface support
        
    
        
    Known problems:
    
        
      
            
    • bug in ntptrace - if no Stratum 1 servers are available, such as on an IntraNet, the application crashes.

    This NTPv3 distribution includes a sample configuration file and the project makefiles for WindowsNT 3.5 platform using Microsoft Visual C++ 2.0 compiler. Also included is a small routine to install the NTP daemon as a "service" on a WindowsNT box. Besides xntpd, the utilities that have been ported are ntpdate and xntpdc. The port to WindowsNT 3.5 has been tested using a Bancomm TimeServe2000 GPS receiver clock that acts as a stratum 1 NTP server with no authentication (it has not been tested with any refclock drivers compiled in).
		
    Following are the known flaws in this port
    
		
      
		
    • Currently, I do not know of a way in NT to get information about multiple network interface cards. The current port uses just one socket bound to INADDR_ANY address. Therefore when dealing with a multihomed NT time server, clients should point to the default address on the server (otherwise the reply is not guaranteed to come from the same interface to which the request was sent). Working with Microsoft to get this resolved.
		
    • There is some problem with "longjmp" in xntpdc/ntpdc.c that causes a software exception on doing a Control-C in xntpdc. Be patient!> 3) The error messages logged by xntpd currently contain only the numerical error code. Corresponding error message string has to be looked up in "Books Online" on Visual C++ 2.0 under the topic "Numerical List of Error Codes".

From: Andy Chittenden 

Dave

Here is a uuencoded, compressed tar file. The only file I've
changed is Makefile - I've included the full file rather than diffs.
There are some new files as well:

	xntp	shell script that starts up ntp during boot up
		(the packaging stuff creates links to it so it comes
		up at run level 2). As with all svr4 start/stop
		scripts, it takes one parameter which is either
		start or stop. It assumes that ntp.conf is in
		/etc/inet/ntp.conf (where it should be on svr4
		machines).
	prototype	describes the file contents of the package.
			You might like to review its contents to
			see whether you want to include any other
			files or remove some. NB I've made the man 
			pages go into 1m as they should on svr4.
	preinstall	runs before installation takes place. It
			ensures that ntp is down if it is up before
			installing a replacement package
	postinstall	starts up ntp after package installation.
	preremove	brings down ntp before removing the package.

You create a package using "make package". This creates a file
called xntp.pkg. To install this package, you use 
"pkgadd -d `pwd`/xntp.pkg xntp". This will start up ntp if
/etc/inet/ntp.conf exists. If you don't want the package anymore, use 
"pkgrm xntp". I have tested this on Solaris 2.4.

indicate that the ntpd process is trying to use unavailable sched_
calls, it means you are running a kernel that does not have the POSIX
scheduling calls enabled.

You have two choices:

- Ignore the messages

- Generate a new kernel, where the kernel configuration file contains
  the lines:

  options		"P1003_1B"
  options		"_KPOSIX_PRIORITY_SCHEDULING"
  options		"_KPOSIX_VERSION=199309L"

Compilation using gcc fails with ntp_config.c. The problem is an apparent
error in the /usr/include/sys/procset.h and /usr/include/sys/wait.h

    Introduction
    


    This page describes the various cryptographic authentication provisions  in
	NTPv4. Details about the configuration commands and options are given on
	the Configuration
	Options page. Details about the automatic server discovery schemes are described
	on the Automatic Server Discovery Schemes page. Additional
	information is available in the papers, reports, memoranda and briefings
	cited on the  NTP Project page.
	Authentication support allows the NTP client to verify that servers are in
	fact known and trusted and not intruders intending accidentally or intentionally
	to masquerade as a legitimate server.
    


     The NTPv3 specification RFC-1305 defines a  scheme properly described as
	symmetric key cryptography. It uses the Data Encryption Standard (DES)
	algorithm operating in cipher-block chaining (CBC) mode. Subsequently, this
	scheme was replaced by the RSA Message Digest 5 (MD5) algorithm commonly
	called keyed-MD5. Either algorithm computes a message digest or one-way hash
	which can be used to verify the client has the same key and key identifier
	as the server. If the OpenSSL cryptographic library is installed, support
	is available for all algorithms included in the library. Note however, if
	conformance to FIPS 140-2 is required, only a limited subset of these algorithms
	is available.
    


    NTPv4 includes the NTPv3 scheme
	and optionally a new scheme based on public key cryptography and called
	Autokey. Public key cryptography is generally considered more secure than
	symmetric key cryptography, since the security is based on private and public
	values which are generated by each participant and where the private value
	is never revealed. Autokey uses X.509 public certificates, which can be produced
	by commercial services, utility programs in the OpenSSL software library
	or the ntp-keygen utility
	program in the NTP software distribution.
    


    While the algorithms for MD5 symmetric key cryptography are included in the
	NTPv4 software distribution, modern algorithms for symmetric key and public
	key cryptograpny   requires the OpenSSL software library
	to be installed before building the NTP distribution. This library is available
	from http://www.openssl.org and
	can be installed using the procedures outlined in the Building
	and Installing the Distribution page. Once installed, the configure and
	build process automatically detects the library and links the library routines
	required.
    


    Note that according to US law, NTP binaries including OpenSSL library components,
	including the OpenSSL library itself, cannot be exported outside the
	US without license from the US Department of Commerce. Builders outside the
	US are advised to obtain the OpenSSL library directly from OpenSSL, which
	is outside the US, and build outside the US.
    


    Authentication is configured separately for each association using the key or autokey option of the server configuration command, as described in the Server Options page, and the options described on this page. The ntp-keygen page describes the files required for the various authentication schemes. Further details are in the briefings, papers and reports at the NTP project page linked from www.ntp.org.
    


    Symmetric Key Cryptography
    


    The original RFC-1305 specification allows any one of possibly 65,534 keys
	(excluding zero), each distinguished by a 32-bit key ID, to authenticate
	an association. The servers and clients involved must agree on the key, key
	ID and key type to authenticate NTP packets. If an NTP packet includes a
	message authentication code (MAC), consisting of a key ID and message digest,
	it is accepted only if the key ID matches a trusted key and the message digest
	is verified with this key. Note that for historic reasons the message digest
	algorithm is not consistent with RFC-1828. The digest is computed directly
	from the concatenation of the key string followed by the packet contents
	with the exception of the MAC itself.
    
 

    Keys and related information are specified in a keys file, usually called ntp.keys,
	which must be distributed and stored using secure means beyond the scope
	of the NTP protocol itself. Besides the keys used for ordinary NTP associations,
	additional keys can be used as passwords for the ntpq and ntpdc utility
	programs. Ordinarily, the ntp.keys file is generated by the ntp-keygen program,
	but it can be constructed and edited using an ordinary text editor. The
	program generates pseudo-random keys, one key for each line. Each line consists
	of three fields, the key identifier as a decimal number from 1 to 65534 inclusive,
	a key type chosen from the  keywords of the digest option of the crypto command,
	and a 20-character printable ASCII string or a 40-character hex string as
	the key itself.
    


    When ntpd is first started, it reads the key file specified by the keys command and installs the keys in the key cache. However, individual keys must be activated with the trustedkey configuration command before use. This allows, for instance, the installation of possibly several batches of keys and then activating a key remotely using ntpdc. The requestkey command selects the key ID used as the password for the ntpdc utility, while the controlkey command selects the key ID used as the password for the ntpq utility.
    

    By default, the message digest algorithm is MD5 selected by the key type
	M in the keys file. However, if the OpenSSL library is installed,
	any message digest algorithm supported by that library can be used. The key
	type is selected as the algorithm name given in the OpenSSL documentation.
	The key type is associated with the key and can be different for different
	 keys. The server and client
	must share the same key, key ID and key type and both must be trusted. Note
	that if conformance to FIPS 140-2 is required, the message digest algorithm
	must conform to the Secure Hash Standard (SHS), which requires an algorithm
	from the Secure Hash Algorithm (SHA) family, and the digital signature encryption
	algorithm, if used, must conform to the Digital Signature Standard (DSS),
	which requires the Digital Signature Algorithm (DSA).
    

    In addition to the above means,  ntpd now  supports
	  Microsoft Windows MS-SNTP authentication using Active Directory services.
	This support was contributed by the Samba Team and is still in development.
	It is enabled using the mssntp flag
	of the restrict command described on
	the Access Control Options page. Note:
	Potential users should be aware that these services involve a TCP connection
	to another process that could potentially block, denying services to other
	users. Therefore, this flag should be used only for a dedicated server with
	no clients other than MS-SNTP.
    

    Public Key Cryptography
    


    NTPv4 supports the Autokey security protocol, which is based on public key cryptography. The Autokey Version 2 protocol described on the Autokey Protocol page verifies packet integrity using MD5 message digests and verifies the source using digital signatures and any of several digest/signature schemes. Optional identity schemes described on the Autokey Identity Schemes page are based on cryptographic challenge/response exchanges. These schemes provide strong security against replay with or without message modification, spoofing, masquerade and most forms of clogging attacks. These schemes are described along with an executive summary, current status, briefing slides and reading list on the Autonomous Authentication page.
    


    Autokey authenticates individual packets using cookies bound to the IP source and destination addresses. The cookies must have the same addresses at both the server and client. For this reason operation with network address translation schemes is not possible. This reflects the intended robust security model where government and corporate NTP servers are operated outside firewall perimeters.
    


    There are three timeouts associated with the Autokey scheme. The key list timeout, which defaults to about 1.1 h, specifies the interval between generating new key lists. The revoke timeout, which defaults to about 36 h, specifies the interval between generating new private values. The restart timeout, with default about 5 d, specifies the interval between protocol restarts to refresh public values. In general, the behavior when these timeouts expire is not affected by the issues discussed on this page.
    


    NTP Secure Groups
    


    NTP secure groups are used to define cryptographic compartments and security
	hierarchies. All hosts belonging to a secure group have the same group name
	but different host names. The string specified in the host option of
	the crypto command is the name of the host and the name used in the
	host key, sign key and certificate files. The string specified in the ident option
	of the crypto command is the group name of all group hosts and the
	name used in the identity files. The file naming conventions are described on
	the ntp-keygen page.
    


    Each group includes one or more trusted hosts (THs) operating at the root, or lowest stratum in the group. The group name is used in the subject and issuer fields of the TH self-signed trusted certificate for these hosts. The host name is used in the subject and issuer fields of the self-signed certificates for all other hosts.
    


    All group hosts are configured to provide an unbroken path, called a certificate trail, from each host, possibly via intermediate hosts and ending at a TH. When a host starts up, it recursively retrieves the certificates along the trail in order to verify group membership and avoid masquerade and middleman attacks.
    


    Secure groups can be configured as hierarchies where a TH of one group can be a client of one or more other groups operating at a lower stratum. A certificate trail consist of a chain of hosts starting at a client, leading through secondary servers of progressively lower stratum and ending at a TH. In one scenario, groups RED and GREEN can be cryptographically distinct, but both be clients of group BLUE operating at a lower stratum. In another scenario, group CYAN can be a client of multiple groups YELLOW and MAGENTA, both operating at a lower stratum. There are many other scenarios, but all must be configured to include only acyclic certificate trails.
    


    Identity Schemes and Cryptotypes
    


    All configurations include a public/private host key pair and matching certificate. Absent an identity scheme, this is a Trusted Certificate (TC) scheme. There are three identity schemes, IFF, GQ and MV described on the Identity Schemes page. With these schemes all servers in the group have encrypted server identity keys, while clients have nonencrypted client identity parameters. The client parameters can be obtained from a trusted agent (TA), usually one of the THs of the lower stratum group. Further information on identity schemes is on the Autokey Identity Schemes page.
    


    A specific combination of authentication and identity schemes is called a
	cryptotype, which applies to clients and servers separately. A group can be
	configured using more than one cryptotype combination, although not all combinations
	are interoperable. Note however that some cryptotype combinations may successfully
	intemperate with each other, but may not represent good security practice. The
	server and client cryptotypes are defined by the the following codes.
    


    

    NONE
    

    A client or server is type NONE if authentication is not available or not configured. Packets exchanged between client and server have no MAC.
    


    AUTH
    

    A client or server is type AUTH if the key option is specified with the server configuration command and the client and server keys are compatible. Packets exchanged between clients and servers have a MAC.
    


    PC
    

    A client or server is type PC if the autokey option is specified with the server configuration command and compatible host key and private certificate files are present. Packets exchanged between clients and servers have a MAC.
    


    TC
    

    A client or server is type TC  if the autokey option is specified with the server configuration command and compatible host key and public certificate files are present. Packets exchanged between clients and servers have a MAC.
    


    IDENT
    
			
    A client or server is type IDENT  if the autokey option is specified with the server configuration command and compatible host key, public certificate and identity scheme files are present. Packets exchanged between clients and servers have a MAC.
    


    


    The compatible cryptotypes for clients and servers are listed in the following table.

    * These combinations are not valid if the restriction list includes the notrust option.
    


    Configuration
    
	

    Autokey has an intimidating number of configuration options, most of which are not necessary in typical scenarios. The simplest scenario consists of a TH where the host name of the TH is also the name of the group. For the simplest identity scheme TC, the TH generates host key and trusted certificate files using the ntp-keygen -T command, while the remaining group hosts use the same command with no options to generate the host key and public certificate files. All hosts use the crypto configuration command with no options. Configuration with passwords is described in the ntp-keygen page. All group hosts are configured as an acyclic tree with root the TH.
    


    When an identity scheme is included, for example IFF, the TH generates host
	key, trusted certificate and private server identity key files using the ntp-keygen
	-T -I -i group command, where group is the group
	name. The remaining group hosts use the same command as above. All hosts
	use the crypto ident group configuration command.
    


    Hosts with no dependent clients can retrieve client parameter files from an
	archive or web page. The ntp-keygen can export these data using the -e option.
	Hosts with dependent clients other than the TH must retrieve copies of the server
	key files using secure means. The ntp-keygen can export these data
	using the -q option. In either case the data are installed as a file
	and then renamed using the name given as the first line in the file, but without
	the filestamp.
    


    Examples
    


    
gif

    


    Consider a scenario involving three secure groups RED, GREEN and BLUE. RED and BLUE are typical of national laboratories providing certified time to the Internet at large. As shown ion the figure, RED TH mort and BLUE TH macabre run NTP symmetric mode with each other for monitoring or backup. For the purpose of illustration, assume both THs are primary servers. GREEN is typical of a large university providing certified time to the campus community. GREEN TH howland is a broadcast client of both RED and BLUE. BLUE uses the IFF scheme, while both RED and GREEN use the GQ scheme, but with different keys. YELLOW is a client of GREEN and for purposes of illustration a TH for YELLOW.
    


    The BLUE TH macabre uses configuration commands
    


    crypto pw qqsv ident blue
    
peer mort autokey
    
broadcast address autokey
    


    where qqsv is the password for macabre files and address is the broadcast address for the local LAN. It generates BLUE files using the commands
    


    ntp-keygen -p qqsv -T -G -i blue
    
ntp-keygen -p qqsv -e >ntpkey_gqpar_blue
    


    The first line generates the host, trusted certificate and private GQ server keys file. The second generates the public GQ client parameters file, which can have any nonconflicting mnemonic name.
    


    The RED TH mort uses configuration commands
    


    crypto pw xxx ident red
    
peer macabre autokey
    
broadcast address autokey
    


    where xxx is the password for mort files. It generates RED files using the commands
    


    ntp-keygen -p xxx -T -I -i red
    
ntp-keygen -p xxx -e >ntpkey_iffpar_red
    


     The GREEN TH howland uses configuration commands
    


    crypto pw yyy ident green
    
broadcastclient
    


    where yyy is the password for howland files. It generates GREEN files using the commands
    


    ntp-keygen -p yyy -T -G -i green
    
ntp-keygen -p yyy -e >ntpkey_gqpar_green
    
ntp-keygen -p yyy -q zzz >zzz_ntpkey_gqkey_green
    


    The first two lines serve the same purpose as the preceding examples. The
	third line generates a copy of the private GREEN server file for use on another
	server in the same group, say YELLOW, but encrypted with the zzz password.
    


    A client of GREEN, for example YELLOW, uses the configuration commands
    


    crypto pw abc ident green
    
server howland autokey
    


    where abc is the password for its files. It generates files using the command
    


    ntp-keygen -p abc
    


    The client retrieves the client file for that group from a public archive or web page using nonsecure means. In addition, each server in a group retrieves the private server keys file from the TH of that group, but it is encrypted and so must be sent using secure means. The files are installed in the keys directory with name taken from the first line in the file, but without the filestamp.
    


    Note that if servers of different groups, in this case RED and BLUE, share the same broadcast media, each server must have client files for all groups other than its own, while each client must have client files for all groups. Note also that this scenario is for illustration only and probably would not be wise for practical use, as if one of the TH reference clocks fails, the certificate trail becomes cyclic. In such cases the symmetric path between RED and BLUE, each in a different group, would not be a good idea.
    


    Authentication Commands
    


    


    automax [logsec]
    

    Specifies the interval between regenerations of the session key list used with the Autokey protocol, as a power of 2 in seconds. Note that the size of the key list for each association depends on this interval and the current poll interval. The default interval is 12 (about 1.1 h). For poll intervals above the specified interval, a session key list with a single entry will be regenerated for every message sent.
    


    controlkey keyid
    

    Specifies the key ID to use with the ntpq utility, which uses the
	standard protocol defined in RFC-1305. The keyid
	argument is the key ID for a trusted
	key, where the value can be in the range 1 to 65534,
	inclusive.
    


    crypto [randfile file] [host name] [ident name] [pw password]
    

    This command requires the OpenSSL library. It activates public key cryptography
	and loads the required host key and public certificate. If one or more files
	are left unspecified, the default names are used as described below. Unless
	the complete path and name of the file are specified, the location of a file
	is relative to the keys directory specified in the keysdir configuration
	command or default /usr/local/etc. Following are the options.
    


    


    digest MD2 | MD4 | MD5 | MDC2 | RIPEMD160 | SHA | SHA1
    

    Specify the message digest algorithm, with default MD5. If the OpenSSL library
	is installed, name can be be any message digest algorithm supported
	by the library  not exceeding 160 bits in length. However, all Autokey
	participants in an Autokey subnet must use the same algorithm. Note that
	the Autokey message digest algorithm is separate and distinct form the symmetric
	key message digest algorithms. Note: If compliance with FIPS 140-2 is required,
	the algorithm must be ether SHA or SHA1.
    


    host name
    

    Specifies the string used when constructing the names for the host, sign
	and certificate files generated by the ntp-keygen program  with the -s name option.
    


    ident name
    

    Specifies the string used in constructing the identity files generated by the ntp-keygen program with the -i name option.
    


    pw password
    

    Specifies the password to decrypt files previously encrypted by the ntp-keygen program with the -p option.
    


    randfile file
    

    Specifies the location of the random seed file used by the OpenSSL library. The defaults are described on the ntp-keygen page.
    


    


    keys keyfile
    

    Specifies the complete path to the MD5 key file containing the keys and key IDs used by ntpd, ntpq and ntpdc when operating with symmetric key cryptography. This is the same operation as the -k command line option. Note that the directory path for Autokey media is specified by the keysdir command.
    


    keysdir pathK
    

    This command specifies the default directory path for Autokey cryptographic keys, parameters and certificates. The default is /usr/local/etc/. Note that the path for the symmetric keys file is specified by the keys command.
    


    requestkey keyid
    

    Specifies the key ID to use with the
	ntpdc utility program, which
	uses a proprietary protocol specific to this implementation of
	ntpd. The keyid argument is a key ID
	for a trusted key, in the range 1 to
	65534, inclusive.
    


    revoke [logsec]
    

    Specifies the interval between re-randomization of certain cryptographic values used by the Autokey scheme, as a power of 2 in seconds. These values need to be updated frequently in order to deflect brute-force attacks on the algorithms; however, updating some values is a relatively expensive operation. The default interval is 17 (about 36 h). For poll intervals above the specified interval, the values will be updated for every message sent.
    


    trustedkey [keyid | (lowid ... highid)] [...]
    

    Specifies the key ID(s) which are trusted for the purposes of
	authenticating peers with symmetric key cryptography.  Key IDs
	used to authenticate ntpq and ntpdc operations
	must be listed here and additionally be enabled with
	controlkey and/or
	requestkey. The authentication
	procedure for time transfer require that both the local and
	remote NTP servers employ the same key ID and secret for this
	purpose, although different keys IDs may be used with different
	servers. Ranges of trusted key IDs may be specified:
	"trustedkey (1 ... 19) 1000 (100 ... 199)" enables the
	lowest 120 key IDs which start with the digit 1. The spaces
	surrounding the ellipsis are required when specifying a range.
    

    


    Error Codes
    


    Errors can occur due to mismatched configurations, unexpected protocol restarts, expired certificates and unfriendly people. In most cases the protocol state machine recovers automatically by retransmission, timeout and restart, where necessary. Some errors are due to mismatched keys, digest schemes or identity schemes and must be corrected by installing the correct media and/or correcting the configuration file. One of the most common errors is expired certificates, which must be regenerated and signed at least once per year using the ntp-keygen - generate public and private keys program.
    


    The following error codes are reported via the NTP control and monitoring protocol trap mechanism and to the cryptostats monitoring file if configured.
    


    


    101 bad field format or length
    

    The packet has invalid version, length or format.
    


    102 bad timestamp
    

    The packet timestamp is the same or older than the most recent received. This could be due to a replay or a server clock time step.
    


    103 bad filestamp
    

    The packet filestamp is the same or older than the most recent received. This could be due to a replay or a key file generation error.
    


    104 bad or missing public key
    

    The public key is missing, has incorrect format or is an unsupported type.
    


    105 unsupported digest type
    

    The server requires an unsupported digest/signature scheme.
    


    106 unsupported identity type
    

    The client or server has requested an identity scheme the other does not support.
    


    107 bad signature length
    

    The signature length does not match the current public key.
    


    108 signature not verified
    

    The message fails the signature check. It could be bogus or signed by a different private key.
    


    109 certificate not verified
    

    The certificate is invalid or signed with the wrong key.
    


    110 host certificate expired
    

    The old server certificate has expired.
    


    111 bad or missing cookie
    

    The cookie is missing, corrupted or bogus.
    


    112 bad or missing leapseconds table
    

    The leapseconds table is missing, corrupted or bogus.
    


    113 bad or missing certificate
    

    The certificate is missing, corrupted or bogus.
    


    114 bad or missing group key
    

    The identity key is missing, corrupt or bogus.
    


    115 protocol error
    

    The protocol state machine has wedged due to unexpected restart.
    


    


    Files
    


    See the ntp-keygen page. Note that provisions to load leap second values from the NIST files have been removed. These provisions are now available whether or not the OpenSSL library is available. However, the functions that can download these values from servers remains available.

    NTP Interleaved Modes

    You need a little magic.

    In the protocol described in the NTP specification and implemented today the transmit timestamp is captured before the MD5 digest is computed and the packet is sent, while the receive timestamp is captured after the packet is received.  For enhanced accuracy it is desirable to capture the timestamps as close to the wire as possible; i.e., with hardware assist or with a modified driver.
    
		
     The problem is, while the receive timestamp could in principle  be piggybacked in the receive buffer, the transmit timestamp cannot ordinarily be transmitted in the same packet. A solution for this problem is the two-step or interleaved protocol described on this page and included in the the current reference implementation. In this experimental variant the transmit timestamp for one packet is actually carried in the immediately following packet. The trick, however, is to implement the interleaved protocol without changing the NTP packet header format, without compromising backwards compatibility and without compromising the error recovery properties.
    
		
    Currently, the reference implementation uses only software timestamps (softstamps). The receive softstamp is captured at software interrupt time and before the buffer is queued for later processing. The reference implementation captures a softstamp before the message digest routine and another after the send-packet routine. In this design the latter timestamp can be considered most accurate, as it avoids the kernel latencies and queueing mechanisms. The difference, called the interleaved or output delay, varies from 16 ms for a dual-core, 2.8 GHz Pentium 4 running FreeBSD 6.1 to 1100 ms for a Sun Blade 1500 running Solaris 10.
    
		
    Performacne varies widely between machines and network interface cards on a 100-Mb switched Ethernet where the NTP packet is about 1000 bits or 10 ms. On two identical Pentium 4 machines in symmetric mode, the measured output delay is 16 ms and remaining one-way delay components 45-150 ms. Two LAN segments account for 20 ms, which leaves 25-130 ms for input delay.  On two identical UltraSPARC machines running Solaris 10 in symmetric mode, the measured output delay is 160 ms and remaining one-way delay components 195 ms. Two LAN segments account for 20 ms, which leaves 175 ms for input delay.
    
		
    Performance with the Pentia show a residual jitter of about 20 ms, which is by far the best performance so far. However, much better performance could result if the input delay could be reduced or elminated with driver or hardware timestamps. Should that be done, performance should be in the same order as the the PPS and kernel discipline, which is in the order of 2 ms.
    
		
    Interleaved modes can be used only in NTP symmetric and broadcast modes.
			It is activated by the xleave option with the peer or broadcast configuration
			commands. The NTP protocol automatically reconfigures in normal or
			interleaved mode as required. Ordinary broadcast clients can use
			the same servers as interleaved broadcast clients at the same time.
			Further details are in the white paper NTP
			Interleaved On-Wire Protocol and the briefing Interleaved
			Synchronization Protocols for LANs and Space Data Links.

    Reference Clock Support
    
		
    The NTP Version 4 daemon supports some three dozen different radio, satellite and modem reference clocks plus a special pseudo-clock used for backup or when no other clock source is available. Detailed descriptions of individual device drivers and options can be found in the Reference Clock Drivers page. Additional information can be found in the pages linked there, including the Debugging Hints for Reference Clock Drivers and How To Write a Reference Clock Driver pages. In addition, support for a PPS signal is available as described in Pulse-per-second (PPS) Signal Interfacing page.
    
		
    A reference clock will generally (though not always) be a radio timecode receiver which is synchronized to a source of standard time such as the services offered by the NRC in Canada and NIST and USNO in the US. The interface between the computer and the timecode receiver is device dependent, but is usually a serial port. A device driver specific to each reference clock must be selected and compiled in the distribution; however, most common radio, satellite and modem clocks are included by default. Note that an attempt to configure a reference clock when the driver has not been compiled or the hardware port has not been appropriately configured results in a scalding remark to the system log file, but is otherwise non hazardous.
    
		
    For the purposes of configuration, ntpd treats reference clocks in a manner analogous to normal NTP peers as much as possible. Reference clocks are identified by a syntactically correct but invalid IP address, in order to distinguish them from normal NTP peers. Reference clock addresses are of the form 127.127.t.u, where t is an integer denoting the clock type and u indicates the unit number in the range 0-3. While it may seem overkill, it is in fact sometimes useful to configure multiple reference clocks of the same type, in which case the unit numbers must be unique.
    
		
    The server command is used to configure a reference clock, where the address argument in that command is the clock address. The key, version and ttl options are not used for reference clock support. The mode option is added for reference clock support, as described below. The prefer option can be useful to persuade the server to cherish a reference clock with somewhat more enthusiasm than other reference clocks or peers. Further information on this option can be found in the Mitigation Rules and the prefer Keyword page. The minpoll and maxpoll options have meaning only for selected clock drivers. See the individual clock driver document pages for additional information.
    
		
    The fudge command is used to provide additional information for individual clock drivers and normally follows immediately after the server command. The address argument specifies the clock address. The refid and stratum options control can be used to override the defaults for the device. There are two optional device-dependent time offsets and four flags that can be included in the fudge command as well.
    
		
    The stratum number of a reference clock is by default zero. Since the ntpd daemon adds one to the stratum of each peer, a primary server ordinarily displays an external stratum of one. In order to provide engineered backups, it is often useful to specify the reference clock stratum as greater than zero. The stratum option is used for this purpose. Also, in cases involving both a reference clock and a pulse-per-second (PPS) discipline signal, it is useful to specify the reference clock identifier as other than the default, depending on the driver. The refid option is used for this purpose. Except where noted, these options apply to all clock drivers.
    
		
    Reference Clock Commands
    
		
    
			
    server 127.127.t.u [prefer] [mode int] [minpoll int] [maxpoll int]
			
    This command can be used to configure reference clocks in special ways. The options are interpreted as follows:
				
    
					
    prefer
					
    Marks the reference clock as preferred. All other things being equal, this host will be chosen for synchronization among a set of correctly operating hosts. See the Mitigation Rules and the prefer Keyword page for further information.
					
    mode int
					
    Specifies a mode number which is interpreted in a device-specific fashion. For instance, it selects a dialing protocol in the ACTS driver and a device subtype in the parse drivers.
					
    minpoll int
					
    maxpoll int
					
    These options specify the minimum and maximum polling interval for reference clock messages in seconds, interpreted as dual logarithms (2 ^ x). For most directly connected reference clocks, both minpoll and maxpoll default to 6 (2^16 = 64 s). For modem reference clocks, minpoll defaults to 10 (2^10 = 1024 s = 17.1 m) and maxpoll defaults to 14 (2^14 = 16384 s = 4.5 h). The allowable range is 4 (16 s) to 17 (36.4 h) inclusive.
				
    
			
    fudge 127.127.t.u [time1 sec] [time2 sec]
					[stratum int] [refid string] [flag1 0|1]
					[flag2 0|1] [flag3 0|1] [flag4 0|1]
			
    This command can be used to configure reference clocks in special ways. It must immediately follow the server command which configures the driver. Note that the same capability is possible at run time using the ntpdc program. The options are interpreted as follows:
				
    
					
    time1 sec
					
    Specifies a constant to be added to the time offset produced by the driver, a fixed-point decimal number in seconds. This is used as a calibration constant to adjust the nominal time offset of a particular clock to agree with an external standard, such as a precision PPS signal. It also provides a way to correct a systematic error or bias due to serial port or operating system latencies, different cable lengths or receiver internal delay. The specified offset is in addition to the propagation delay provided by other means, such as internal DIPswitches. Where a calibration for an individual system and driver is available, an approximate correction is noted in the driver documentation pages.
					
    Note: in order to facilitate calibration when more than one radio clock or PPS signal is supported, a special calibration feature is available. It takes the form of an argument to the enable command described in the Miscellaneous Options page and operates as described in the Reference Clock Drivers page.
					
    time2 secs
					
    Specifies a fixed-point decimal number in seconds, which is interpreted in a driver-dependent way. See the descriptions of specific drivers in the reference clock drivers page.
					
    stratum int
					
    Specifies the stratum number assigned to the driver, an integer between 0 and 15. This number overrides the default stratum number ordinarily assigned by the driver itself, usually zero.
					
    refid string
					
    Specifies an ASCII string of from one to four characters which defines the reference identifier used by the driver. This string overrides the default identifier ordinarily assigned by the driver itself.
					
    flag1 flag2 flag3 flag4
					
    These four flags are used for customizing the clock driver. The interpretation of these values, and whether they are used at all, is a function of the particular clock driver. However, by convention flag4 is used to enable recording monitoring data to the clockstats file configured with the filegen command. Further information on the filegen command can be found in the Monitoring Options page.

    Synopsis
    
		ntptrace [ -n ] [ -m maxhosts ] [ server ]
		
    Description
    
		
    ntptrace is a perl script that uses the ntpq utility program to follow the chain of NTP servers from a given host back to the primary time source. For ntptrace to work properly, each of these servers must implement the NTP Control and Monitoring Protocol specified in RFC 1305 and enable NTP Mode 6 packets.
    
		
    If given no arguments, ntptrace starts with localhost. Here is an example of the output from ntptrace:
    
		
    % ntptrace
localhost: stratum 4, offset 0.0019529, synch distance 0.144135
server2ozo.com: stratum 2, offset 0.0124263, synch distance 0.115784
usndh.edu: stratum 1, offset 0.0019298, synch distance 0.011993, refid 'WWVB'

    
		
    On each line, the fields are (left to right): the host name, the host stratum, the time offset between that host and the local host (as measured by ntptrace; this is why it is not always zero for "localhost"), the host synchronization distance, and (only for stratum-1 servers) the reference clock ID. All times are given in seconds. Note that the stratum is the server hop count to the primary source, while the synchronization distance is the estimated error relative to the primary source. These terms are precisely defined in RFC-1305.
    
		
    Options
    
		
    
			
    -n
			
    Turns off the printing of host names; instead, host IP addresses are given. This may be useful if a nameserver is down.

    Introduction
    


    This page summarizes the criteria for choosing from among a number of potential sources suitable contributors to the clock discipline algorithm. The criteria are very meticulous, since they have to handle many different scenarios that may be optimized for peculiar circumstances, including some scenarios designed to support planetary and deep space missions.
    


    Recall the suite of NTP data acquisition and grooming algorithms as these algorithms proceed in five phases. Phase one discovers the available sources and mobilizes an association for each candidate found. These candidates can result from explicit configuration, broadcast discovery or the pool and manycast autonomous configuration schemes. Phase two grooms the selectable candidates excluding those sources showing one or more of the following errors
    


      


    1. A stratum error occurs if (1) the source had never been synchronized or (2) the stratum of the source is below the floor option or not below the ceiling option specified by the tos command. The default value for these options are 0 and 16, respectively.
      2. 


    2. A distance error occurs for a remote source if the root distance is not below the distance threshold maxdist option of the tos command. The default value for this option is 1.5 s for networks including only the Earth, but this should be increased to 2.5 s for networks including the Moon.
      3. 


    3. A loop error occurs if the source is synchronized to the client of if the source is synchronized to the same source as the client.
      4. 


    4. An unreachable error occurs if the source is unreachable or if the server or peer command for the source includes the noselect option.
      5. 


    


    Phase three uses an intersection algorithm to select the truechimers from
	among the candidates, leaving behind the falsetickers. A server or peer configured
	with the true option is ipso facto a truechimer independent of this
	algorithm. Phase four uses a clustering algorithm to cast off statistical outliers
	from the truechimers until a set of survivors not less than the number specified
	as the minclock option of the tos command, with default 3.
	Phase five uses a set of mitigation rules to select from among the survivors
	a system peer from which a set of system statistics can be inherited and passed
	along to a dependent client population. The clock offset developed from these
	algorithms can discipline the system clock either using the ntpd clock
	discipline algorithm or enable the kernel to discipline the system clock directly,
	as described on the A Kernel Model for Precision Timekeeping page.
	Phase five is the topic of this page.
    


    Peer Classification
    


    The behavior of the various algorithms and mitigation rules involved depends on how the various synchronization sources are classified. This depends on whether the source is local or remote and if local the type of source. The following classes are defined:
    


      


    1. An association configured for a remote server or peer is classified simply as a server. All other associations are classified as a device driver of one kind or another. In general, one or more sources of either or both types will be configured in each installation.
      2. 


    2. If all sources have been lost and the orphan stratum has been specified by the orphan option of the tos command, a pseudo-source called the orphan parent is created with offset and jitter both zero. Dependent orphan children will see the orphan parent as if synchronized to a  server at the orphan stratum.If the only survivor is the orphan parent, it becomes the system peer and its clock offset and jitter are inherited by the corresponding system variables. Note that by design all the orphan children having the same set of orphan parents will select the same parent.
      3. 


    3. When a device driver has been configured for pulse-per-second (PPS) signals and PPS signals are being received, it is designated the PPS driver. Note that the Pulse-per-Second driver (type 22) is often used as a PPS driver, but any driver can be operated as a PPS driver as well. The PPS driver provides precision clock discipline only within +-0.5 s, so is always associated with another source or sources that provide the seconds numbering function.
      4. 


    4. When the Undisciplined Local Clock driver (type 1) is configured, it is designated the local driver. This driver is used either as a backup source (stratum greater than zero) should all sources fail, or as the primary source (stratum zero) in cases where the kernel time is disciplined by some other means of synchronization, such as the NIST lockclock scheme, or another synchronization protocol such as the Digital Time Synchronization Service (DTSS).
      5. 


    5. When the Automated Computer Time Service driver (type 18) is configured, it is designated the modem driver. This is used either as a backup source, should all other sources fail, or as the (only) primary source.
      6. 


    


    The prefer Peer
    


    The mitigation rules are designed to provide an intelligent selection of the system peer from among the survivors of different types. When used with the server or peer  commands, the prefer option designates one or more survivors as preferred over all others. While the rules do not forbid it, it is usually not useful to designate more than one source as preferred; however, if more than one source is so designated, they are used in the order specified in the configuration file; that is, if the first one becomes unselectable, the second one is considered and so forth. This order of priority is also applicable to multiple PPS drivers, multiple modem drivers and even multiple local drivers, although that would not normally be useful.
    


    The clustering algorithm works on the set of truechimers produced by the intersection algorithms. Ordinarily, any one of them can in principle provide correct time; however, due to various latency variations, not all can provide the most accurate and stable time. The clustering algorithm, processes the truechimers in one or more rounds to cast off a statistical outlier until no more than the minclock option of the tos command are left. The default for this option is 3.
    


    In the prefer scheme the clustering algorithm is modified so that the prefer peer is never discarded; on the contrary, its potential removal becomes a rounds-termination condition. However, the prefer peer can still be discarded by the intersection algorithm as a falseticker. To avoid this, it is usually wise to increase the mindist option of the tos command from the default .005 s to something like .05 s.
    


    Ordinarily, the combining algorithm computes a weighted average of the survivor
	offsets to produce the final synchronization source. However, if a prefer
	peer is among the survivors, the combining algorithm is not used. Instead,
	the offset of the prefer peer is used exclusively as the final synchronization
	source. In the common case involving a radio clock and a flock of remote backup
	servers, and with the radio clock designated a prefer peer, the result is that
	the radio clock normally disciplines the system clock as long as the radio itself
	remains operational. However, if the radio fails or becomes a falseticker,
	the averaged backup sources continue to discipline the system clock.
    


    Mitigation Rules
    


    As the selection algorithm scans the associations for selectable candidates, the modem driver and local driver are segregated for later, but only if not designated a prefer peer. If so designated, a driver is included among the candidate population. In addition, if orphan parents are found the parent with the lowest  metric is segregated for later; the others are discarded. For this purpose the metric is defined as the four-octet IPv4 address or the first four octets of the hashed IPv6 address. The resulting candidates, including any prefer peers found, are processed by the intersection to produce a possibly empty set of truechimers. The clustering algorithm ranks the truechimers first by stratum then by synchronization distance and designates the survivor with the lowest distance as the potential system peer.
    


    If one or more truechimers support a pulse-per-second (PPS) signal and the
	PPS signal is operating correctly, it is designated a PPS driver. If more than
	one PPS diver are found, only the first one is used. The PPS driver is not included
	in the combining algorithm and is mitigated separately.
    


    At this point we have the following contributors to the system clock discipline:
    


      


    • (potential) system peer, if there are survivors;
      • 

    • orphan parent, if present;
      • 

    • local driver and zero offset, if present;
      • 

    • modem driver and modem offset, if present;
      • 

    • prefer peer and offset, if present;
      • 

    • PPS driver and offset, if present.
      • 

    


    The mitigation algorithm proceeds in three steps in turn.
    


      


    1. If there are no survivors, the modem driver becomes the only survivor if there is one. If not, the local driver becomes the only survivor if there is one. If not, the orphan parent becomes the only survivor if there is one. If the number of survivors at this point is less than the minsane option of the tos command, the algorithm is terminated and the system variables remain unchanged. Note that minsane is by default 1, but can be set at any value including 0.
      2. 


    2. If the prefer peer is among the survivors, it becomes the system peer and its clock offset and jitter are inherited by the corresponding system variables. Otherwise, the combining algorithm computes these variables from the survivor population.
      3. 


    3. If there is a PPS driver and the system clock offset at this point is less than 0.4 s, and if there is a prefer peer among the survivors or if the PPS peer is designated as a prefer peer, the PPS driver becomes the system peer and its offset and jitter are inherited by the system variables, thus overriding any variables already computed. Note that a PPS driver is present only if PPS signals are actually being received and enabled by the associated driver.
      4. 


    


    If none of the above is the case, the data are disregarded and the system variables remain as they are.
    


    The minsane Option
    


     The minsane option of the tos command, the prefer option of the server and peer commands and the flag options of the fudge command for the PPS driver can be used with the mitigation rules to provide many useful configurations. The minsane option specifies the minimum number of survivors required to synchronized the system clock. The prefer option designates the prefer peer. The driver-dependent flag options enable the PPS driver for various conditions.
    


    A common scenario is a GPS driver with a serial timecode and PPS signal. The
	PPS signal is disabled until the system clock has been set by some means, not
	necessarily the GPS driver. If the serial timecode is within 0.4 s of the PPS
	signal, the GPS driver is designated the PPS driver and the PPS signal disciplines
	the system clock. If no GPS satellites are in view, or if the PPS signal is
	disconnected, the GPS driver stops updating the system clock and so eventually
	becomes unreachable and replaced by other sources..
    


    Whether or not the GPS driver disables the PPS signal when unreachable is
at the discretion of the driver. Ordinarily, the PPS signal would be disabled in this case; however, When the GPS receiver has a precision holdover oscillator, the driver may elect to continue PPS operation. In this case the PPS signal continues to discipline the system clock.

    Synopsis
    
		ntpdc [ -46dilnps ] [ -c command ] [ host ] [ ... ]
		
    Description
    
		
    ntpdc is used to query the ntpd daemon about its current state and to request changes in that state. The program may be run either in interactive mode or controlled using command line arguments. Extensive state and statistics information is available through the ntpdc interface. In addition, nearly all the configuration options which can be specified at startup using ntpd's configuration file may also be specified at run time using ntpdc.
    
		
    If one or more request options are included on the command line when ntpdc is executed, each of the requests will be sent to the NTP servers running on each of the hosts given as command line arguments, or on localhost by default. If no request options are given, ntpdc will attempt to read commands from the standard input and execute these on the NTP server running on the first host given on the command line, again defaulting to localhost when no other host is specified. ntpdc will prompt for commands if the standard input is a terminal device.
    
		
    ntpdc uses NTP mode 7 packets to communicate with the NTP server, and hence can be used to query any compatible server on the network which permits it. Note that since NTP is a UDP protocol this communication will be somewhat unreliable, especially over large distances in terms of network topology. ntpdc makes no attempt to retransmit requests, and will time requests out if the remote host is not heard from within a suitable timeout time.
    
		
    The operation of ntpdc are specific to the particular implementation of the ntpd daemon and can be expected to work only with this and maybe some previous versions of the daemon. Requests from a remote ntpdc program which affect the state of the local server must be authenticated, which requires both the remote program and local server share a common key and key identifier.
    
		
    Note that in contexts where a host name is expected, a -4 qualifier preceding the host name forces DNS resolution to the IPv4 namespace, while a -6 qualifier forces DNS resolution to the IPv6 namespace.
    
		
    Command Line Options
    
		
    Specifying a command line option other than -i or -n will cause the specified query (queries) to be sent to the indicated host(s) immediately. Otherwise, ntpdc will attempt to read interactive format commands from the standard input.
    
		
    
			
    -4
			
    Force DNS resolution of following host names on the command line to the IPv4 namespace.
			
    -6
			
    Force DNS resolution of following host names on the command line to the IPv6 namespace.
			
    -c command
			
    The following argument is interpreted as an interactive format command and is added to the list of commands to be executed on the specified host(s). Multiple -c options may be given.
			
    -d
			
    Turn on debugging mode.
			
    -i
			
    Force ntpdc to operate in interactive mode. Prompts will be written to the standard output and commands read from the standard input.
			
    -l
			
    Obtain a list of peers which are known to the server(s). This switch is equivalent to -c listpeers.
			
    -n
			
    Output all host addresses in dotted-quad numeric format rather than converting to the canonical host names.
			
    -p
			
    Print a list of the peers known to the server as well as a summary of their state. This is equivalent to -c peers.
			
    -s
			
    Print a list of the peers known to the server as well as a summary of their state, but in a slightly different format than the -p switch. This is equivalent to -c dmpeers.
		
    
		
    Interactive Commands
    
		
    Interactive format commands consist of a keyword followed by zero to four arguments. Only enough characters of the full keyword to uniquely identify the command need be typed. The output of a command is normally sent to the standard output, but optionally the output of individual commands may be sent to a file by appending a <, followed by a file name, to the command line.
    
		
    A number of interactive format commands are executed entirely within the ntpdc program itself and do not result in NTP mode 7 requests being sent to a server. These are described following.
    
		
    
			
    ? [ command_keyword ]
    
				help [ command_keyword ]
			
    A ? by itself will print a list of all the command keywords known to this incarnation of ntpq. A ? followed by a command keyword will print function and usage information about the command. This command is probably a better source of information about ntpq than this manual page.
			
    delay milliseconds
			
    Specify a time interval to be added to timestamps included in requests which require authentication. This is used to enable (unreliable) server reconfiguration over long delay network paths or between machines whose clocks are unsynchronized. Actually the server does not now require timestamps in authenticated requests, so this command may be obsolete.
			
    host hostname
			
    Set the host to which future queries will be sent. Hostname may be either a host name or a numeric address.
			
    hostnames [ yes | no ]
			
    If yes is specified, host names are printed in information displays. If no is specified, numeric addresses are printed instead. The default is yes, unless modified using the command line -n switch.
			
    keyid keyid
			
    This command allows the specification of a
		key number to be used to authenticate configuration
		requests from ntpdc to the host(s). This must
		correspond to a key number which the host/server has
		been configured to use for this purpose (server
		options: trustedkey, and
		requestkey).  If authentication is not
		enabled on the host(s) for ntpdc
		commands, the command
		"keyid 0" should be given; otherwise the
		keyid of the next subsequent addpeer/addserver/broadcast
			 command will
			be used.  
			
    quit
			
    Exit ntpdc.
			
    passwd
			
    This command prompts you to type in a password (which will not be echoed) which will be used to authenticate configuration requests. The password must correspond to the key configured for use by the NTP server for this purpose if such requests are to be successful.
			
    timeout milliseconds
			
    Specify a timeout period for responses to server queries. The default is about 8000 milliseconds. Note that since ntpdc retries each query once after a timeout, the total waiting time for a timeout will be twice the timeout value set.
		
    
		
    Control Message Commands
    
		
    Query commands result in NTP mode 7 packets containing requests for information being sent to the server. These are read-only commands in that they make no modification of the server configuration state.
    
		
    
			
    listpeers
			
    Obtains and prints a brief list of the peers for which the server is maintaining state. These should include all configured peer associations as well as those peers whose stratum is such that they are considered by the server to be possible future synchronization candidates.
			
    peers
			
    Obtains a list of peers for which the server is maintaining state, along with a summary of that state. Summary information includes the address of the remote peer, the local interface address (0.0.0.0 if a local address has yet to be determined), the stratum of the remote peer (a stratum of 16 indicates the remote peer is unsynchronized), the polling interval, in seconds, the reachability register, in octal, and the current estimated delay, offset and dispersion of the peer, all in seconds.
				
    The character in the left margin indicates the mode this peer entry is operating in. A + denotes symmetric active, a - indicates symmetric passive, a = means the remote server is being polled in client mode, a ^ indicates that the server is broadcasting to this address, a ~ denotes that the remote peer is sending broadcasts and a * marks the peer the server is currently synchronizing to.
    
				
    The contents of the host field may be one of four forms. It may be a host name, an IP address, a reference clock implementation name with its parameter or REFCLK(implementation number, parameter). On hostnames no only IP-addresses will be displayed.
    
			
    dmpeers
			
    A slightly different peer summary list. Identical to the output of the peers command, except for the character in the leftmost column. Characters only appear beside peers which were included in the final stage of the clock selection algorithm. A . indicates that this peer was cast off in the falseticker detection, while a + indicates that the peer made it through. A * denotes the peer the server is currently synchronizing with.
			
    showpeer peer_address [...]
			
    Shows a detailed display of the current peer variables for one or more peers. Most of these values are described in the NTP Version 2 specification.
			
    pstats peer_address [...]
			
    Show per-peer statistic counters associated with the specified peer(s).
			
    clockinfo clock_peer_address [...]
			
    Obtain and print information concerning a peer clock. The values obtained provide information on the setting of fudge factors and other clock performance information.
			
    kerninfo
			
    Obtain and print kernel phase-lock loop operating parameters. This information is available only if the kernel has been specially modified for a precision timekeeping function.
			
    loopinfo [ oneline | multiline ]
			
    Print the values of selected loop filter variables. The loop filter is the part of NTP which deals with adjusting the local system clock. The offset is the last offset given to the loop filter by the packet processing code. The frequency is the frequency error of the local clock in parts-per-million (ppm). The time_const controls the stiffness of the phase-lock loop and thus the speed at which it can adapt to oscillator drift. The watchdog timer value is the number of seconds which have elapsed since the last sample offset was given to the loop filter. The oneline and multiline options specify the format in which this information is to be printed, with multiline as the default.
			
    sysinfo
			
    Print a variety of system state variables, i.e., state related to the local server. All except the last four lines are described in the NTP Version 3 specification, RFC-1305.
				
    The system flags show various system flags, some of which can be set and cleared by the enable and disable configuration commands, respectively. These are the auth, bclient, monitor, pll, pps and stats flags. See the ntpd documentation for the meaning of these flags. There are two additional flags which are read only, the kernel_pll and kernel_pps. These flags indicate the synchronization status when the precision time kernel modifications are in use. The kernel_pll indicates that the local clock is being disciplined by the kernel, while the kernel_pps indicates the kernel discipline is provided by the PPS signal.
    
				
    The stability is the residual frequency error remaining after the system frequency correction is applied and is intended for maintenance and debugging. In most architectures, this value will initially decrease from as high as 500 ppm to a nominal value in the range .01 to 0.1 ppm. If it remains high for some time after starting the daemon, something may be wrong with the local clock, or the value of the kernel variable tick may be incorrect.
    
				
    The broadcastdelay shows the default broadcast delay, as set by the broadcastdelay configuration command.
    
				
    The authdelay shows the default authentication delay, as set by the authdelay configuration command.
    
			
    sysstats
			
    Print statistics counters maintained in the protocol module.
			
    memstats
			
    Print statistics counters related to memory allocation code.
			
    iostats
			
    Print statistics counters maintained in the input-output module.
			
    timerstats
			
    Print statistics counters maintained in the timer/event queue support code.
			
    reslist
			
    Obtain and print the server's restriction list. This list is (usually) printed in sorted order and may help to understand how the restrictions are applied.
			
    ifstats
			
    List interface statistics for interfaces used by ntpd for network communication.
    
			
    ifreload
			
    Force rescan of current system interfaces. Outputs interface statistics for interfaces that could possibly change. Marks unchanged interfaces with ., added interfaces with + and deleted interfaces with -.
    
			
    monlist [ version ]
			
    Obtain and print traffic counts collected and maintained by the monitor facility. The version number should not normally need to be specified.
			
    clkbug clock_peer_address [...]
			
    Obtain debugging information for a reference clock driver. This information is provided only by some clock drivers and is mostly undecodable without a copy of the driver source in hand.
		
    
		
    Runtime Configuration Requests
    
		
    All requests which cause state changes in the server are authenticated by the server using a configured NTP key (the facility can also be disabled by the server by not configuring a key). The key number and the corresponding key must also be made known to ntpdc. This can be done using the keyid and passwd commands, the latter of which will prompt at the terminal for a password to use as the encryption key. You will also be prompted automatically for both the key number and password the first time a command which would result in an authenticated request to the server is given. Authentication not only provides verification that the requester has permission to make such changes, but also gives an extra degree of protection again transmission errors.
    
		
    Authenticated requests always include a timestamp in the packet data, which is included in the computation of the authentication code. This timestamp is compared by the server to its receive time stamp. If they differ by more than a small amount the request is rejected. This is done for two reasons. First, it makes simple replay attacks on the server, by someone who might be able to overhear traffic on your LAN, much more difficult. Second, it makes it more difficult to request configuration changes to your server from topologically remote hosts. While the reconfiguration facility will work well with a server on the local host, and may work adequately between time-synchronized hosts on the same LAN, it will work very poorly for more distant hosts. As such, if reasonable passwords are chosen, care is taken in the distribution and protection of keys and appropriate source address restrictions are applied, the run time reconfiguration facility should provide an adequate level of security.
    
		
    The following commands all make authenticated requests.
    
		
    
		
    addpeer peer_address [
		keyid ] [ version ] [
		minpoll# | prefer | iburst  | burst | minpoll
		N | maxpoll N [...]  ]
		
    addpeer peer_address [
		prefer | iburst | burst | minpoll
		N | maxpoll N | keyid
			N | version N [...]  ]
			
    Add a configured peer association at the
			given address and operating in symmetric
			active mode. Note that an existing association
			with the same peer may be deleted when this
			command is executed, or may simply be
			converted to conform to the new configuration,
			as appropriate. If the keyid
			is nonzero, all outgoing packets to
			the remote server will have an authentication
			field attached encrypted with this key. If the
			value is 0 (or not given) no authentication
			will be done. If ntpdc's key number has not
			yet been set (e.g., by the keyid
			command), it will be set to this value.
			The version# can be 1 through 4 and defaults to 3.  The remaining
			options are either a numeric value for minpoll or
			literals prefer, iburst, 
			burst, minpoll  N,
			keyid N, version  N, or
			maxpoll  N (where N is a numeric value), and have the action as specified in the
			peer configuration file command of
			ntpd.  See the Server Options page for further information.
			Each flag (or its absence) replaces the
			previous setting. The prefer keyword indicates a preferred peer (and thus will be used primarily for clock synchronisation if possible). The preferred peer also determines the validity of the PPS signal - if the preferred peer is suitable for synchronisation so is the PPS signal.
			The dynamic keyword allows association configuration even when no suitable network interface is found at configuration time. The dynamic interface update mechanism may complete the configuration when new interfaces appear (e.g. WLAN/PPP interfaces) at a later time and thus render the association operable.
			
    addserver peer_address [
		keyid ] [ version ] [
		minpoll# | prefer | iburst  | burst | minpoll
		N | maxpoll N [...]  ]
		
    addserver peer_address [
		prefer | iburst | burst | minpoll
		N | maxpoll N | keyid
			N | version N [...]  ]
			
    Identical to the addpeer command, except that the operating mode is client.
			
    broadcast peer_address [
			keyid ] [ version ] [ prefer ]
			
    Identical to the addpeer command, except
			that the operating mode is broadcast. In this
			case a valid non-zero key identifier and key are required. The peer_address parameter can be the broadcast address of the local network or a multicast group address assigned to NTP. If a multicast address, a multicast-capable kernel is required.
			
    unconfig peer_address [...]
			
    This command causes the configured bit to be removed from the specified peer(s). In many cases this will cause the peer association to be deleted. When appropriate, however, the association may persist in an unconfigured mode if the remote peer is willing to continue on in this fashion.
			
    fudge peer_address [ time1 ] [ time2 ] [ stratum ] [ refid ]
			
    This command provides a way to set certain data for a reference clock. See the source listing for further information.
			
    enable [ auth | bclient | calibrate | kernel | monitor | ntp | pps | stats]
    
				disable [ auth | bclient | calibrate | kernel | monitor | ntp | pps | stats]
			
    These commands operate in the same way as the enable and disable configuration file commands of ntpd. See the Miscellaneous Options page for further information.
			
    restrict address mask flag [ flag ]
			
    This command operates in the same way as the restrict configuration file commands of ntpd.
			
    unrestrict address mask flag [ flag ]
			
    Unrestrict the matching entry from the restrict list.
			
    delrestrict address mask [ ntpport ]
			
    Delete the matching entry from the restrict list.
			
    readkeys
			
    Causes the current set of authentication keys to be purged and a new set to be obtained by rereading the keys file (which must have been specified in the ntpd configuration file). This allows encryption keys to be changed without restarting the server.
			
    trustedkey keyid [...]
			
    untrustedkey keyid [...]
			
    These commands operate in the same way as the trustedkey and untrustedkey configuration file commands of ntpd.
			
    authinfo
			
    Returns information concerning the authentication module, including known keys and counts of encryptions and decryptions which have been done.
			
    traps
			
    Display the traps set in the server. See the source listing for further information.
			
    addtrap [ address ] [ port ] [ interface ]
			
    Set a trap for asynchronous messages. See the source listing for further information.
			
    clrtrap [ address ] [ port ] [ interface]
			
    Clear a trap for asynchronous messages. See the source listing for further information.
			
    reset
			
    Clear the statistics counters in various modules of the server. See the source listing for further information.
		
    
		
    Bugs
    
		
    ntpdc is a crude hack. Much of the information it shows is deadly boring and could only be loved by its implementer. The program was designed so that new (and temporary) features were easy to hack in, at great expense to the program's ease of use. Despite this, the program is occasionally useful.

    Access Control Support
    


    The ntpd daemon implements a general purpose access control list
	(ACL) containing address/match entries sorted first by increasing address
	values and then by increasing mask values. A match occurs when the bitwise
	AND of the mask and the packet source address is equal to the bitwise AND of
	the mask and address in the list. The list is searched in order with the last
	match found defining the restriction flags associated with the entry.
    


    An example may clarify how it works. Our campus has two class-B networks,
128.4 for the ECE and CIS departments and 128.175 for the rest of campus.
Let's assume (not true!) that subnet 128.4.1 homes critical services like class
	rosters and spread sheets. A suitable ACL might be
    

    restrict default nopeer					# deny new associations
restrict 128.175.0.0 mask 255.255.0.0 		# allow campus access
restrict 128.4.0.0 mask 255.255.0.0 none	# allow ECE and CIS access
restrict 128.4.1.0 mask 255.255.255.0 notrust # require authentication on subnet 1
restrict time.nist.gov						# allow access

    


    While this facility may be useful for keeping unwanted, broken or malicious clients from congesting innocent servers, it should not be considered an alternative to the NTP authentication facilities. Source address based restrictions are easily circumvented by a determined cracker.
    


    Access Control Commands
    


    


    discard [ average avg ][ minimum min ] [ monitor prob ]
    

    Set the parameters of the rate control facility which protects the server
	from client abuse. If the limited flag is present in the ACL, packets
	that violate these limits are discarded. If in addition the kod restriction
	is present, a kiss-o'-death packet is returned.
    


    


    average avg
    

    Specify the minimum average interpacket spacing (minimum average headway
time) in log2 s with default 3.
    


    minimum min
    

    Specify the minimum interpacket spacing (guard time) in log2 s
	with default 1.
    


    monitor
    

    Specify the probability of discard for packets that overflow the rate-control
	window. This is a performance optimization for servers with aggregate arrivals
	of 1000 packets per second or more.
    


    
			

    restrict address [mask mask] [flag][...]
    

    The address argument expressed in dotted-quad form is the
	address of a host or network. Alternatively, the address argument
	can be a valid host DNS name. The mask argument expressed in
	dotted-quad form defaults to 255.255.255.255, meaning that the address is
	treated as the address of an individual host. A default entry (address 0.0.0.0,
	mask 0.0.0.0) is always included and is always the first entry in the list.
	Note that the text string default, with no mask option, may be used
	to indicate the default entry.
    


    Some flags have the effect to deny service, some  have the effect to
	enable service and some are  conditioned by other flags. The  flags. are
	not orthogonal, in that more restrictive flags will often make less restrictive
	ones redundant. The flags that deny service are classed in two categories,
	those that restrict time service and those that restrict informational queries
	and attempts to do run-time reconfiguration of the server. One or more of the
	following flags may be specified:
    

    


    flake
    

    Discard received NTP packets with probability 0.1; that is, on average drop
	one packet in ten. This is for testing and amusement. The name comes from Bob
	Braden's flakeway, which once did a similar thing for early Internet
	testing.
    


    ignore
    

    Deny packets of all kinds, including ntpq and ntpdc queries.
    


    kod
    

    Send a kiss-o'-death (KoD) packet if the limited flag is present
	and a packet violates the rate limits established by the discard command.
	KoD packets are themselves rate limited for each source address separately.
	If this flag is not present, packets that violate the rate limits are discarded.
    


    limited
    

    Deny time service if the packet violates the rate limits established by the discard command.
	This does not apply to ntpq and ntpdc queries.
    


    lowpriotrap
    

    Declare traps set by matching hosts to be low priority. The number of traps
	a server can maintain is limited (the current limit is 3). Traps are usually
	assigned on a first come, first served basis, with later trap requestors being
	denied service. This flag modifies the assignment algorithm by allowing low
	priority traps to be overridden by later requests for normal priority traps.
    

    mssntp
    

    Enable Microsoft Windows MS-SNTP authentication using Active Directory services.
	Note: Potential users should be aware that these services
	involve a TCP connection to another process that could potentially block,
	denying services to other users. Therefore, this flag should be used only
	for a dedicated  server with no clients other than MS-SNTP.
    

    nomodify
    

    Deny ntpq and ntpdc queries which attempt to modify the
	state of the server (i.e., run time reconfiguration). Queries which return information
	are permitted.
    


    noquery
    

    Deny ntpq and ntpdc queries. Time service is not affected.
    


    nopeer
    

    Deny packets that might  mobilize an  association unless authenticated. This
	includes broadcast, symmetric-active and manycast server packets when a configured
	association does not exist. Note that this flag does not apply to packets
	that do not attempt to mobilize an association. 
    


    noserve
    

    Deny all packets except ntpq and ntpdc queries.
    


    notrap
    

    Decline to provide mode 6 control message trap service to matching hosts.
	The trap service is a subsystem of the ntpdc control message protocol
	which is intended for use by remote event logging programs.
    


    notrust
    

    Deny packets that are not cryptographically authenticated. Note carefully
	how this flag interacts with the auth option of the enable and disable commands.
	If  auth is enabled, which is the default, authentication is required
	for all packets that might mobilize  an association.
	If auth is
	disabled, but the notrust flag is not present, an association can be
	mobilized whether or not authenticated. If auth is disabled, but the notrust flag
	is present, authentication is required only for the specified address/mask
	range. 
    

		
    ntpport
    
			
    non-ntpport
    
			
    This is actually a match algorithm modifier, rather than a restriction
				flag. Its presence causes the restriction entry to be matched only if the
				source port in the packet is the standard NTP UDP port (123). Both ntpport and non-ntpport may
				be specified. The ntpport is considered more specific and is sorted
				later in the list.
    
			
    version
    
			
    Deny packets that do not match the current NTP version.
    
		
    

    

    Default restriction list entries with the flags ignore, ntpport,
	for each of the local host's interface addresses are inserted into the table
	at startup to prevent the server from attempting to synchronize to its own time.
	A default entry is also always present, though if it is otherwise unconfigured;
	no flags are associated with the default entry (i.e., everything besides your
	own NTP server is unrestricted).

    Disclaimer: The functionality of this program is now available in the ntpd program. See the -q command line option in the ntpd - Network Time Protocol (NTP) daemon page. After a suitable period of mourning, the ntpdate program is to be retired from this distribution
    
		
    Synopsis
    
		ntpdate [ -46bBdqsuv ] [ -a key ] [ -e authdelay ] [ -k keyfile ] [ -o version ] [ -p samples ] [ -t timeout ] server [ ... ]
		
    Description
    
		
    ntpdate sets the local date and time by polling the Network Time Protocol (NTP) server(s) given as the server arguments to determine the correct time. It must be run as root on the local host. A number of samples are obtained from each of the servers specified and a subset of the NTP clock filter and selection algorithms are applied to select the best of these. Note that the accuracy and reliability of ntpdate depends on the number of servers, the number of polls each time it is run and the interval between runs.
    
		
    ntpdate can be run manually as necessary to set the host clock, or it can be run from the host startup script to set the clock at boot time. This is useful in some cases to set the clock initially before starting the NTP daemon ntpd. It is also possible to run ntpdate from a cron script. However, it is important to note that ntpdate with contrived cron scripts is no substitute for the NTP daemon, which uses sophisticated algorithms to maximize accuracy and reliability while minimizing resource use. Finally, since ntpdate does not discipline the host clock frequency as does ntpd, the accuracy using ntpdate is limited.
    
		
    Time adjustments are made by ntpdate in one of two ways. If ntpdate determines the clock is in error more than 0.5 second it will simply step the time by calling the system settimeofday() routine. If the error is less than 0.5 seconds, it will slew the time by calling the system adjtime() routine. The latter technique is less disruptive and more accurate when the error is small, and works quite well when ntpdate is run by cron every hour or two.
    
		
    ntpdate will decline to set the date if an NTP server daemon (e.g., ntpd) is running on the same host. When running ntpdate on a regular basis from cron as an alternative to running a daemon, doing so once every hour or two will result in precise enough timekeeping to avoid stepping the clock.
    
		
    Note that in contexts where a host name is expected, a -4 qualifier preceding the host name forces DNS resolution to the IPv4 namespace, while a -6 qualifier forces DNS resolution to the IPv6 namespace.
    
		
    If NetInfo support is compiled into ntpdate, then the server argument is optional if ntpdate can find a time server in the NetInfo configuration for ntpd.
    
		
    Command Line Options
    
		
    
			
    -4
			
    Force DNS resolution of following host names on the command line to the IPv4 namespace.
			
    -6
			
    Force DNS resolution of following host names on the command line to the IPv6 namespace.
			
    -a key
			
    Enable the authentication function and specify the key identifier to be used for authentication as the argument key. The keys and key identifiers must match in both the client and server key files. The default is to disable the authentication function.
			
    -B
			
    Force the time to always be slewed using the adjtime() system call, even if the measured offset is greater than +-500 ms. The default is to step the time using settimeofday() if the offset is greater than +-500 ms. Note that, if the offset is much greater than +-500 ms in this case, that it can take a long time (hours) to slew the clock to the correct value. During this time. the host should not be used to synchronize clients.
			
    -b
			
    Force the time to be stepped using the settimeofday() system call, rather than slewed (default) using the adjtime() system call. This option should be used when called from a startup file at boot time.
			
    -d
			
    Enable the debugging mode, in which ntpdate will go through all the steps, but not adjust the local clock. Information useful for general debugging will also be printed.
			
    -e authdelay
			
    Specify the processing delay to perform an authentication function as the value authdelay, in seconds and fraction (see ntpd for details). This number is usually small enough to be negligible for most purposes, though specifying a value may improve timekeeping on very slow CPU's.
			
    -k keyfile
			
    Specify the path for the authentication key file as the string keyfile. The default is /etc/ntp.keys. This file should be in the format described in ntpd.
			
    -o version
			
    Specify the NTP version for outgoing packets as the integer version, which can be 1 or 2. The default is 4. This allows ntpdate to be used with older NTP versions.
			
    -p samples
			
    Specify the number of samples to be acquired from each server as the integer samples, with values from 1 to 8 inclusive. The default is 4.
			
    -q
			
    Query only - don't set the clock.
			
    -s
			
    Divert logging output from the standard output (default) to the system syslog facility. This is designed primarily for convenience of cron scripts.
			
    -t timeout
			
    Specify the maximum time waiting for a server response as the value timeout, in seconds and fraction. The value is is rounded to a multiple of 0.2 seconds. The default is 1 second, a value suitable for polling across a LAN.
			
    -u
			
    Direct ntpdate to use an unprivileged port for outgoing packets. This is most useful when behind a firewall that blocks incoming traffic to privileged ports, and you want to synchronize with hosts beyond the firewall. Note that the -d option always uses unprivileged ports.
			
    -v
			
    Be verbose. This option will cause ntpdate's version identification string to be logged.
		
    
		
    Diagnostics
    
		ntpdate's exit status is zero if it finds a server and updates the clock, and nonzero otherwise.
		
    Files
    
		/etc/ntp.keys - encryption keys used by ntpdate.
		
    Bugs
    
		The slew adjustment is actually 50% larger than the measured offset, since this (it is argued) will tend to keep a badly drifting clock more accurate. This is probably not a good idea and may cause a troubling hunt for some values of the kernel variables tick and tickadj.

    Description
    
		
    The ntpdsim program is an adaptation of the ntpd operating system daemon. The program operates as a discrete time simulator using specified systematic and random driving sources. It includes all the mitigation and discipline algorithms of the actual daemon, but with the packet I/O and system clock algorithms driven by simulation. Most functions of the real ntpd remain intact, including the monitoring, statistics recording, trace and host name resolution features. Further information on the simulator is on the NTP Discrete Event Simulator page.
    
		
    The simulator is most useful to study NTP behavior in response to time and/or frequency transients under specific conditions of network jitter and oscillator wander. For this purpose the daemon can be driven by pseudorandom jitter and wander sample sequences characteristic of real networks and oscillators. The jitter generator produces samples from a Poisson distribution, while the wander generator produces samples from a Guassian distribution.
    
		
    The easiest way to use this program is to create a ntpstats directory, configuration file ntp.conf and frequency file ntp.drift and test shell test.sh in the base directory. The ntp.drift file and ntpstats directory can be empty to start. The test.sh script can contain something like
    
		
    rm ./ntpstats/*
ntpdsim -O 0.1 -C .001 -T 400 -W 1 -c ./ntp.conf,

    
		
    which starts the simulator with a time offset 100 ms, network jitter 1 ms, frequency offset 400 PPM and oscillator wander 1 PPM/s. These parameters represent typical conditions with modern workstations on a Ethernet LAN. The ntp.conf file should contain something like
    
		
    disable kernel
server pogo
driftfile ./ntp.drift
statsdir ./ntpstats/
filegen loopstats type day enable
filegen peerstats type day enable

    
		
    Command Line Options
    
		
    
			
    Note: The NTP development team is moving to the use of a syntax-directed configuration file design. When complete these options will be replaced by a new one. Most of the ntpd command line options apply also to ntpdsim. In addition, the following command line options apply to ntpdsim.
			
    -B bdly
			
    Specify beep delay (3600) s.
			
    -C snse
			
    Specify network jitter parameter (0) s.

    NTP PARSE clock data formats
    
		
    The parse driver currently supports several clocks with different query mechanisms. In order for you to find a sample that might be similar to a clock you might want to integrate into parse I'll sum up the major features of the clocks (this information is distributed in the parse/clk_*.c and ntpd/refclock_parse.c files).
    
		
    
		
    Meinberg clocks
    
		
    Meinberg: start=<STX>, end=<ETX>, sync on start
      pattern="\2D:  .  .  ;T: ;U:  .  .  ;    \3"
      pattern="\2  .  .  ;  ;   :  :  ;        \3"
      pattern="\2  .  .  ;  ;   :  :  ;    :  ;        ;   .         .       "

    
		
    Meinberg is a German manufacturer of time code receivers. Those clocks have a pretty common output format in the stock version. In order to support NTP Meinberg was so kind to produce some special versions of the firmware for the use with NTP. So, if you are going to use a Meinberg clock please ask whether there is a special Uni Erlangen version. You can reach Meinberg via the Web. Information can also be ordered via eMail from info@meinberg.de
    
		
    General characteristics:
    
			Meinberg clocks primarily output pulse per second and a describing ASCII string. This string can be produced in two modes: either upon the reception of a question mark or every second. NTP uses the latter mechanism. DCF77 AM clocks have a limited accuracy of a few milliseconds. The DCF77 PZF5xx variants provide higher accuracy and have a pretty good relationship between RS232 time code and the PPS signal. Except for early versions of the old GPS166 receiver type, Meinberg GPS receivers have a very good timing relationship between the datagram and the pulse. The beginning of the start bit of the first character has basically the same accuracy as the PPS signal, plus a jitter of up to 1 bit time depending on the selected baud rate, i.e. 52 μs @ 19200. PPS support should always be used, if possible, in order to yield the highest possible accuracy.
    
		
    The preferred tty setting for Meinberg DCF77 receivers is 9600/7E2:
    
		
    		CFLAG		(B9600|CS7|PARENB|CREAD|HUPCL)
		IFLAG		(IGNBRK|IGNPAR|ISTRIP)
		OFLAG		0
		LFLAG		0
        
    
		
    The tty setting for Meinberg GPS16x/17x receivers is 19200/8N1:
    
		
    		CFLAG		(B19200|CS8|PARENB|CREAD|HUPCL)
		IFLAG		(IGNBRK|IGNPAR|ISTRIP)
		OFLAG		0
		LFLAG		0
        
    
		
    All clocks should be run at datagram once per second.

    Examples for Uni Erlangen strings from GPS receivers:
    

            \x02 09.07.93; 5; 08:48:26; +00:00;        ; 49.5736N  11.0280E  373m \x03
        \x02 08.11.06; 3; 14:39:39; +00:00;        ; 51.9828N   9.2258E  176m \x03

    
		
    The Uni Erlangen formats should be used preferably. Newer Meinberg GPS receivers can be configured to transmit that format, for older devices there may be a special firmware version available.
    
		
    For the Meinberg parse look into clk_meinberg.c

    RAWDCF: end=TIMEOUT>1.5s, sync each char (any char),generate psuedo time codes, fixed format
    
		
    direct DCF77 code input
    
		
    In Europe it is relatively easy/cheap the receive the german time code transmitter DCF77. The simplest version to process its signal is to feed the 100/200ms pulse of the demodulated AM signal via a level converter to an RS232 port at 50Baud. parse/clk_rawdcf.c holds all necessary decoding logic for the time code which is transmitted each minute for one minute. A bit of the time code is sent once a second.
    
		
    	The preferred tty setting is:
		CFLAG           (B50|CS8|CREAD|CLOCAL)
		IFLAG		0
		OFLAG		0
 		LFLAG		0

    
		
    DCF77 raw time code
    
		
    From "Zur Zeit", Physikalisch-Technische Bundesanstalt (PTB), Braunschweig und Berlin, März 1989
    
		
    
		
    Timecode transmission:
    
		
    	AM:

	time marks are send every second except for the second before the
	next minute mark
	time marks consist of a reduction of transmitter power to 25%
	of the nominal level
	the falling edge is the time indication (on time)
	time marks of a 100ms duration constitute a logical 0
	time marks of a 200ms duration constitute a logical 1

    
		
    see the spec. (basically a (non-)inverted psuedo random phase shift) encoding:

    Schmid clock
    
		
    Schmid clock: needs poll, binary input, end='\xFC', sync start
    
		
    The Schmid clock is a DCF77 receiver that sends a binary time code at the reception of a flag byte. The contents if the flag byte determined the time code format. The binary time code is delimited by the byte 0xFC.
    
		
    	TTY setup is:
		CFLAG		(B1200|CS8|CREAD|CLOCAL)
		IFLAG		0
		OFLAG		0
 		LFLAG		0


    
		
    The command to Schmid's DCF77 clock is a single byte; each bit allows the user to select some part of the time string, as follows (the output for the lsb is sent first).
    
		
    	Bit 0:	time in MEZ, 4 bytes *binary, not BCD*; hh.mm.ss.tenths
	Bit 1:	date 3 bytes *binary, not BCD: dd.mm.yy
	Bit 2:	week day, 1 byte (unused here)
	Bit 3:	time zone, 1 byte, 0=MET, 1=MEST. (unused here)
	Bit 4:	clock status, 1 byte,	0=time invalid,
					1=time from crystal backup,
					3=time from DCF77
	Bit 5:	transmitter status, 1 byte,
					bit 0: backup antenna
					bit 1: time zone change within 1h
					bit 3,2: TZ 01=MEST, 10=MET
					bit 4: leap second will be
						added within one hour
					bits 5-7: Zero
	Bit 6:	time in backup mode, units of 5 minutes (unused here)

    
		
    
		
    Trimble SV6 ASCII time code (TAIP)
    
		
    Trimble SV6: needs poll, ascii timecode, start='>', end='<', query='>QTM<', eol='<'
    
		
    Trimble SV6 is a GPS receiver with PPS output. It needs to be polled. It also need a special tty mode setup (EOL='<').
    
		
    	TTY setup is:
		CFLAG            (B4800|CS8|CREAD)
		IFLAG            (BRKINT|IGNPAR|ISTRIP|ICRNL|IXON)
		OFLAG            (OPOST|ONLCR)
		LFLAG            (ICANON|ECHOK)

    
		
    Special flags are:
    
		
    		PARSE_F_PPSPPS	    - use CIOGETEV for PPS time stamping
		PARSE_F_PPSONSECOND - the time code is not related to
				      the PPS pulse (so use the time code
				      only for the second epoch)

    WHARTON 400A Series Clock with a 404.2 Serial interface
    
		
    The WHARTON 400A Series clock is able to send date/time serial messages in 7 output formats. We use format 1 here because it is the shortest. We set up the clock to send a datagram every second. For use with this driver, the WHARTON 400A Series clock must be set-up as follows :
    
		
      					Programmable	Selected
  					Option No	Option
	BST or CET display		3		9 or 11
	No external controller		7		0
	Serial Output Format 1		9		1
	Baud rate 9600 bps		10		96
	Bit length 8 bits		11		8
	Parity even			12		E

    
		
    WHARTON 400A Series output format 1 is as follows :

    Introduction
    

    The ntpd includes a comprehensive monitoring facility which collects
	statistical data of various types and writes the data to files associated with
	each type at defined events or intervals. The files associated with a particular
	type are collectively called the generation file set for that type. The files
	in the file set are the members of that set.
    

    File sets have names specific to the type and generation epoch. The names
	are constructed from three concatenated elements prefix, filename and suffix:
    

    
	
    prefix
    
	
    The directory path specified in the statsdir command.
    
	
    name
    
	
    The name specified by the file option of the filegen command.
    
	
    suffix
    
	
    A string of elements bdginning with . (dot) followed by a number of elements
		depending on the file set type.
    

    

    Statistics files can be managed using scripts, examples of which are in the ./scripts directory.
	Using these or similar scripts and Unix cron jobs, the files can be
	automatically summarized and archived for retrospective analysis.
    

    Monitoring Commands
    

    
	
    filegen name file filename [type type]
			[link | nolink] [enable | disable]
    
	
    
		
    
			
    name
    
			
    Specifies the file set type from the list in the next section.
    
			
    file filename
    
			
    Specfies the file set name.
    
			
    type typename
    
			
    Specifies the file set interval. The following intervals are supported
				with default day:
    
			
    
				
    
					
    none
    
					
    The file set is actually a single plain file.
    
					
    pid
    
					
    One file set member is created for every incarnation of ntpd.
						The file name suffix is the string .n, where n is the
						process ID of the ntpd server process.
    
					
    day
    
					
    One file set member is created per day. A day is defined as the period
						between 00:00 and 23:59 UTC. The file name suffix is the string .yyyymmdd,
						where yyyy is the year, mm the month of the year and dd the
						day of the month. Thus, member created on 10 December 1992 would have suffix .19921210.
    
					
    week
    
					
    One file set member is created per week. The week is defined as the
						day of year modulo 7. The file name suffix is the string .yyyyWww,
						where yyyy is the year, W stands for itself and ww the
						week number starting from 0. For example, The member created on 10 January
						1992 would have suffix .1992W1.
    
					
    month
    
					
    One file set member is created per month. The file name suffix is the
						string .yyyymm, where yyyy is the year and mm the
						month of the year starting from 1. For example, The member created on 10
						January 1992 would have suffix .199201.
    
					
    year
    
					
    One file set member is generated per year. The file name suffix is the
						string .yyyy, where yyyy is the year. For example, The
						member created on 1 January 1992 would have suffix .1992.
    
					
    age
    
					
    One file set member is generated every 24 hours of ntpd operation.
						The filename suffix is the string .adddddddd, where a stands
						for itself and dddddddd is the ntpd running time in seconds
						at the start of the corresponding 24-hour period.
    
				
    
			
    
			
    link | nolink
    
			
    It is convenient to be able to access the current file set members by
				file name, but without the suffix. This feature is enabled by link and
				disabled by nolink. If enabled, which is the default, a hard link
				from the current file set member to a file without suffix is created. When
				there is already a file with this name and the number of links to this file
				is one, it is renamed by appending a dot, the letter C, and the
				pid of the ntpd server process. When the number of links is greater
				than one, the file is unlinked. This allows the current file to be accessed
				by a constant name.
    
			
    enable | disable
    
			
    Enable or disable the recording function, with default enable.
				These options are intended for remote configutation commands.
    
		
    
	
    
	
    statsdir directory_path
    
	
    Specify the directory path prefix for statistics file names.

    Description
    
		
    The ntpdsim program is used to simulate and study the behavior of an NTP daemon that derives its time from a number of different simulated time sources (servers). Each simulated server can be configured to have a different time offset, frequency offset, propagation delay, processing delay, network jitter and oscillator wander.
    
		
    The ntpdsim program runs all the same selection, mitigation, and discipline
			algorithms as the actual ntpd daemon at the client. (It actually
			uses the same code). However, the input/output routines and servers are simulated.
			That is, instead of sending the client messages over the network
			to the actual servers, the client messages are intercepted by the ntpdsim
			program, which then generates the replies to those messages. The reply messages
			are carefully "inserted" into the input queue of the client at the right time
			according to the specified server properties (like propagation delay).
    
		
    Each simulated server runs according to a specified script that describes the server properties at a particular time. Each script consists of a series of consecutive acts. Each act runs for a particular duration and specifies the frequency offset, propagation delay, processing delay, network jitter and oscillator wander of the server for that duration. Once the duration of an act expires, the simulated server reconfigures itself according to the properties specified in the next act.
    
		
    Configuration
    
		
    The ntpdsim program is configured by providing a configuration file at startup. The crux of the simulator configuration is specified using a simulate command, the syntax of which is given below. Note that all time quantities are in seconds and all frequency quantities are in parts per million (PPM):
    
		
    <simulate_command> ::= simulate { <init_statement_list> <server_list> }
    
		<init_statement_list> ::= <init_statement_list> <init_statement> | <init_statement>
    
		<init_statement> ::= beep_delay = <number> | simulation_duration = <number>
    
		<server_list> ::= <server_list> <server> | <server>
    
		<server_list> ::= server = <address> { server_offset = <number> <act_list> }
    
		<act_list> ::= <act_list> <act> | <act>
    
		<act> ::= duration = <number> { <act_stmt_list> }
    
		<act_stmt_list> ::= <act_stmt_list> <act_stmt> | <act_stmt>
    
		<act_stmt> ::= freq_offset = <number> | wander = <number> | jitter = <number> | prop_delay = <number> | proc_delay = <number>
    
		
    In addition to the simulate command, other standard NTP configuration commands can be specified. These commands have the same meaning as in the ntpd configuration. Note that newlines are not significant within the simulate command even though they are used to mark the end of a normal NTP configuration command.
    
		
    Sample Configuration File
    
		
    A sample ntpdsim configuration file is given below. It specifies two simulated servers, each of which has two acts.

    NTP Version 4 Release Notes
    
		
    This release of the NTP Version 4 (NTPv4) daemon for Unix, VMS and Windows incorporates new features and refinements to the NTP Version 3 (NTPv3) algorithms. However, it continues the tradition of retaining backwards compatibility with older versions, including NTPv3 and NTPv2, but not NTPv1. Support for NTPv1 has been discontinued because of certain security vulnerabilities. The NTPv4 version has been under development for 25 years and the paint still isn't dry.
    
		
    The code compiles and runs properly in all test host configurations available to the developer corps, including Sun Microsystems, Digital/Compaq/Hewlett Packard, FreeBSD and Linux. Other volunteers have verified it works in IRIX and Windows NT and XP. We invite comments and corrections about the various architectures, operating systems and hardware complement that can't be verified by the developer corps. Of particular interest are other Windows versions, VMS and various reference clock drivers.
    
		
    This release has been compiled and tested on many systems, including SunOS 4.1.3, Solaris 2.5.1-2.10, Alpha Tru64 4.0-5.1, Ultrix 4.4, Linux 2.4.2, FreeBSD 4.5-6.2 and HP-UX 10.02. It has been compiled and tested by others on Windows NT4, 2000 and XP, but not yet on other Windows versions or for VMS. There are several new features apparently incompatible with Linux systems, including some modes used with the Autokey protocol. The developer corps looks for help elsewhere to resolve these differences.
    
		
    This note summarizes the differences between this software release of NTPv4, called ntp-4.x.x, and the previous NTPv3 version, called xntp3-5.x.x.
    
		
    New Features
    
		
      
			
    1. Support for the IPv6 addressing family is included in this distribution. If the Basic Socket Interface Extensions for IPv6 (RFC-2553) is detected, support for the IPv6 address family is generated in addition to the default support for the IPv4 address family.
      2. 
			
    2. Most calculations are now done using 64-bit floating double format, rather than 64-bit fixed point format. The motivation for this is to reduce size, improve speed and avoid messy bounds checking.
      3. 
			
    3. The clock discipline algorithm has been redesigned to improve accuracy, reduce the impact of network jitter and allow increased in poll intervals to 36 hours with only moderate sacrifice in accuracy.
      4. 
			
    4. A new feature called "huffpuff" maximizes accuracy in cases of highly asymmetric network delays typical of ISDN and telephone modems.
      5. 
			
    5. The clock selection algorithm has been redesigned to reduce "clockhopping" when the choice of servers changes frequently as the result of comparatively insignificant quality changes.
      6. 
			
    6. This release includes support for the nanokernel precision time kernel modifications, which are now in stock FreeBSD and optional in Linux kernels. With this support the system clock can be disciplined to the order of one nanosecon. The older microtime kernel modifications in Digital/Compaq/HP Tru64, Digital Ultrix and Sun Microsystems SunOS and Solaris, continue to be supported. In either case the support eliminates sawtooth error, which can be in the hundreds of microseconds.
      7. 
			
    7. This release includes support for Autokey public-key cryptography, which is the preferred scheme for authenticating servers to clients. Additional information about Autokey cryptography is on the Authentication Options page and links from there. See also the new cryptostats monitoring statistics file in the Monitoring Options page.
      8. 
			
    8. The OpenSSL cryptographic library has replaced the library formerly available from RSA Laboratories. All cryptographic routines except a version of the MD5 message digest routine have been removed from the base distribution.
      9. 
			
    9. As the result of the above, the authstuff directory, intended as a development and testing aid for porting cryptographic routines to exotic architectures, has been removed. Testing and conformance validation tools are in the OpenSSL software distrbution.
      10. 
			
    10. This release includes support for a discrete event simulator (DES), which allows the NTP algorithms to be tested in an embedded environment with systematic and pseudorandom network delay and oscillator wander distributions. This has been used to verify correct operation under conditions of extreme error and misconfiguration. See the ntpdsim - Network Time Protocol (NTP) simulator page.
      11. 
			
    11. NTPv4 includes three new server discovery schemes, which in most applications can avoid per-host configuration altogether. Two of these are based on IP multicast technology, while the remaining one is based on crafted DNS lookups. See the Automatic NTP Configuration Schemes page for further information.
      12. 
			
    12. This release includes comprehensive packet rate management tools to help reduce the level of spurious network traffic and protect the busiest servers from overload. See the Rate Management and the Kiss-o'-Death Packet page for further information.
      13. 
			
    13. This release includes support for the orphan mode, which replaces the local clock driver for most configurations. Orphan mode provides an automatic, subnet-wide synchronization feature with multiple sources. It can be used in isolated networks or in Internet subnets where the servers or Internet connection have failed. See the Automatic NTP Configuration Options page for further information.
      14. 
			
    14. There are two new burst mode features available where special conditions apply. One of these is enabled by the iburst keyword in the server configuration command. It is intended for cases where it is important to set the clock quickly when an association is first mobilized. The other is enabled by the burst keyword in the server configuration command. It is intended for cases where the network attachment requires an initial calling or training procedure. See the Association Management page for further information.
      15. 
			
    15. The reference clock driver interface is smaller, more rational and more accurate.
      16. 
			
    16. Support for pulse-per-second (PPS) signals has been extended to all drivers as an intrinsic function. Most of the drivers in NTPv3 have been converted to the NTPv4 interface and continue to operate as before. New drivers have been added for several GPS receivers now on the market for a total of 44 drivers. Audio drivers for the Canadian standard time and frequency station CHU, the US standard time and frequency stations WWV/H and for IRIG signals have been updated and capabilities added to allow direct connection of these signals to an audio port. See the Reference Clock Audio Drivers page for further information.
      17. 
			
    17. In all except a very few cases, all timing intervals are randomized, so that the tendency for NTPv3 to self-synchronize and bunch messages, especially with a large number of configured associations, is minimized.
      18. 
			
    18. In NTPv3 a large number of weeds and useless code had grown over the years since the original NTP code was implemented 25 years ago. Using a powerful weedwacker, much of the shrubbery has been removed, with effect a substantial reduction in size of almost 40 percent.
      19. 
			
    19. The entire distribution has been converted to gnu automake, which should greatly ease the task of porting to new and different programming environments, as well as reduce the incidence of bugs due to improper handling of idiosyncratic kernel functions. Version control is provided by Bitkeeper using an online repository at www.ntp.org. Trouble ticket reporting is provided using Bugzilla.
      20. 
			
    20. Several new options have been added for the ntpd command line. For the inveterate knob twiddlers several of the more important performance variables can be changed to fit actual or perceived special conditions. In particular, the tos and tos commands can be used to adjust thresholds, throw switches and change limits.
      21. 
			
    21. The ntpd daemon can be operated in a one-time mode similar to ntpdate, which program is headed for retirement. See the ntpd - Network Time Protocol (NTP) daemon page for the new features.
      22. 
		
    
		
    Nasty Surprises
    
		
    There are a few things different about this release that have changed since the latest NTP Version 3 release. Following are a few things to worry about:
    
		
      
			
    1. Some configuration commands have been removed, others added and some changed in minor ways. See the Commands and Options collection on the Site Map page.
      2. 
			
    2. When both IPv4 and IPv6 address families are in use, the host's resolver library may not choose the intended address family if a server has an IPv4 and IPv6 address associated with the same DNS name. The solution is to use the IPv4 or IPv6 address directly in such cases or use another DNS name that resolves to the intended address family. Older versions of ntpdc will show only the IPv4 associations with the peers and some other commands. Older versions of ntpq will show 0.0.0.0 for IPv6 associations with the peers and some other commands.
      3. 
			
    3. There is a minor change to the reference ID field of the NTP packet header when operating with IPv6 associations. In IPv4 associations this field contains the 32-bit IPv4 address of the server, in order to detect and avoid loops. In IPv6 associations this field contains the first 32-bits of a MD5 hash formed from the IPv6 address. All programs in the distribution have been modified to work with both address families.
      4. 
			
    4. The tty_clk and ppsclock pulse-per-second (PPS) line discipline/streams modules are no longer supported. The PPS function is now handled by the PPS Clock Discipline driver, which uses the new PPSAPI application program interface adopted by the IETF. Note that the pps configuration file command has been obsoleted by the driver. See the Pulse-per-second (PPS) Signal Interfacing page for further information.
      5. 
			
    5. Support for the NTPv1 symmetric mode has been discontinued, since it hasn't worked for years. Support continues for the NTPv1 client mode, which is used by some SNTP clients.
      6.

    Synopsis
    
		ntpq [-46dinp] [-c command] [host] [...]
		
    Description
    
		
    The ntpq utility program is used to monitor NTP daemon ntpd operations
			and determine performance. It uses the standard NTP mode 6 control
			message formats defined in Appendix B of the NTPv3 specification
			RFC1305. The same formats are used in NTPv4, although some of the
			variable names have changed and new ones added. The description
			on this page is for the NTPv4 variables.
    
		
    The program can be run either in interactive mode or controlled using command line arguments. Requests to read and write arbitrary variables can be assembled, with raw and pretty-printed output options being available. The ntpq can also obtain and print a list of peers in a common format by sending multiple queries to the server.
    
		
    If one or more request options is included on the command line when ntpq is executed, each of the requests will be sent to the NTP servers running on each of the hosts given as command line arguments, or on localhost by default. If no request options are given, ntpq will attempt to read commands from the standard input and execute these on the NTP server running on the first host given on the command line, again defaulting to localhost when no other host is specified. ntpq will prompt for commands if the standard input is a terminal device.
    
		
    ntpq uses NTP mode 6 packets to communicate with the NTP server, and hence can be used to query any compatible server on the network which permits it. Note that since NTP is a UDP protocol this communication will be somewhat unreliable, especially over large distances in terms of network topology. ntpq makes one attempt to retransmit requests, and will time requests out if the remote host is not heard from within a suitable timeout time.
    
		
    Note that in contexts where a host name is expected, a -4 qualifier preceding the host name forces DNS resolution to the IPv4 namespace, while a -6 qualifier forces DNS resolution to the IPv6 namespace.
    
		
    For examples and usage, see the NTP Debugging Techniques page.
    
		
    Command line options are described following. Specifying a command line option other than -i or -n will cause the specified query (queries) to be sent to the indicated host(s) immediately. Otherwise, ntpq will attempt to read interactive format commands from the standard input.
    
		
    
			
    -4
    
			
    Force DNS resolution of following host names on the command line to the IPv4 namespace.
    
			
    -6
    
			
    Force DNS resolution of following host names on the command line to the IPv6 namespace.
    
			
    -c
    
			
    The following argument is interpreted as an interactive format command and is added to the list of commands to be executed on the specified host(s). Multiple -c options may be given.
    
			
    -d
    
			
    Turn on debugging mode.
    
			
    -i
    
			
    Force ntpq to operate in interactive mode. Prompts will be written to the standard output and commands read from the standard input.
    
			
    -n
    
			
    Output all host addresses in dotted-quad numeric format rather than converting to the canonical host names.
    
			
    -p
    
			
    Print a list of the peers known to the server as well as a summary of their state. This is equivalent to the peers interactive command.
    
		
    
		
    Internal Commands
    
		
    Interactive format commands consist of a keyword followed by zero to four arguments. Only enough characters of the full keyword to uniquely identify the command need be typed. The output of a command is normally sent to the standard output, but optionally the output of individual commands may be sent to a file by appending a >, followed by a file name, to the command line. A number of interactive format commands are executed entirely within the ntpq program itself and do not result in NTP mode-6 requests being sent to a server. These are described following.
    
		
    
			
    ? [command_keyword]
    
				help [command_keyword]
    
			
    A ? by itself will print a list of all the command keywords known to  ntpq. A ? followed by a command keyword will print function and usage information about the command.
    
			
    addvars name [ = value] [...]
    
				rmvars name [...]
    
				clearvars
    
			
    The arguments to this command consist of a list of items of the form name = value, where the = value is ignored, and can be omitted in read requests. ntpq maintains an internal list in which data to be included in control messages can be assembled, and sent using the readlist and writelist commands described below. The addvars command allows variables and optional values to be added to the list. If more than one variable is to be added, the list should be comma-separated and not contain white space. The rmvars command can be used to remove individual variables from the list, while the clearlist command removes all variables from the list.
    
			
    cooked
    
			
    Display server messages in prettyprint format.
    
			
    debug more | less | off
    
			
    Turns internal query program debugging on and off.
    
			
    delay milliseconds
    
			
    Specify a time interval to be added to timestamps included in requests which require authentication. This is used to enable (unreliable) server reconfiguration over long delay network paths or between machines whose clocks are unsynchronized. Actually the server does not now require timestamps in authenticated requests, so this command may be obsolete.
    
			
    host name
    
			
    Set the host to which future queries will be sent. The name may be either a DNS name or a numeric address.
    
			
    hostnames [yes | no]
    
			
    If yes is specified, host names are printed in information displays. If no is specified, numeric addresses are printed instead. The default is yes, unless modified using the command line -n switch.
    
			
    keyid keyid
    
			
    This command specifies the key number to be used to authenticate configuration requests. This must correspond to a key number the server has been configured to use for this purpose.
    
			
    ntpversion 1 | 2 | 3 | 4
    
			
    Sets the NTP version number which ntpq claims in packets. Defaults to 2, Note that mode-6 control messages (and modes, for that matter) didn't exist in NTP version 1.
    
			
    passwd
    
			
    This command prompts for a password to authenticate configuration requests. The password must correspond to the key configured for NTP server for this purpose.
    
			
    quit
    
			
    Exit ntpq.
    
			
    raw
    
			
    Display server messages as received and without reformatting.
    
			
    timeout milliseconds
    
			
    Specify a timeout period for responses to server queries. The default is about 5000 milliseconds. Note that since ntpq retries each query once after a timeout, the total waiting time for a timeout will be twice the timeout value set.
    
		
    
		
    Control Message Commands
    
		
    Association IDs are used to identify system, peer and clock variables. System variables are assigned an association ID of zero and system name space, while each association is assigned a nonzero association ID and peer namespace. Most control commands send a single mode-6 message to the server and expect a single response message. The exceptions are the peers command, which sends a series of messages, and the mreadlist and mreadvar commands, which iterate over a range of associations.

    readvar assocID name [ = value ] [,...]
    
				rv assocID [ name ] [,...]
    
			
    Display the specified variables. If assocID is zero, the
				variables are from the system variables name space,
				otherwise they are from the peer variables name space.
				The assocID	is required, as the same name can occur in both spaces. If no name is
			included, all operative variables in the name space are displayed.
			In this case only, if the assocID is omitted, it is assumed zero. Multiple
			names are specified with comma separators and without whitespace.
			Note that time values are represented in milliseconds and frequency
			values in parts-per-million (PPM). Some NTP timestamps are represented
			in the format YYYYMMDDTTTT, where YYYY is the year, MM the month
			of year, DD the day of month and TTTT the time of day.
    
			
    saveconfig filename
    
			
    Write the current configuration, including any runtime modifications given with :config or config-from-file, to the ntpd host's file filename.  This command will be rejected by the server unless saveconfigdir appears in the ntpd configuration file.  filename can use strftime() format specifiers to substitute the current date and time, for example, saveconfig ntp-%Y%m%d-%H%M%S.conf. The filename used is stored in system variable savedconfig. Authentication is required.
    
			
    writevar assocID name = value [,...]
    
			
    Write the specified variables. If the assocID is  zero, the variables
			are from the system variables name space, otherwise they are from the peer variables name	space. The assocID is required, as the same name can occur
			in both spaces.
    
	
    
	
    Status Words and Kiss Codes
    
		
    The current state of the operating program is shown in a set of status words maintained by the system and each association separately. These words are displayed in the rv and as commands both in hexadecimal and decoded short tip strings. The codes, tips and short explanations are on the Event Messages and Status Words page. The page also includes a list of system and peer messages, the code for the latest of which is included in the status word.
    
		
    Information resulting from protocol machine state transitions is displayed using an informal set of ASCII strings called kiss codes. The original purpose was for kiss-o'-death (KoD) packets sent by the server to advise the client of an unusual condition. They are now displayed, when appropriate, in the reference identifier field in various billboards.

    Description
    
		
    This driver supports the Chrono-log K-series WWVB receiver. This is a very old receiver without provisions for leap seconds, quality codes, etc. It assumes output in the local time zone, and that the C library mktime()/localtime() routines will correctly convert back and forth between local and UTC. There is a hack in the driver for permitting UTC, but it has not been tested.
    
		
    Most of this code is originally from refclock_wwvb.c with thanks. It has been so mangled that wwvb is not a recognizable ancestor.

    Arcron MSF Receiver
    
		
    
		
    Synopsis
    
		
    Address: 127.127.27.u
    
			Reference ID: MSFa / MSF / DCF / WWVB
    
			Driver ID: MSF_ARCRON
    
			Serial Port: /dev/arcu; 300 baud, 8-bits, 2-stop, no parity
    
			Features: tty_clk
    
		
    Description
    
		
    This driver supports the Arcron MSF, DCF and WWVB receivers. The clock reports its ID as "MSFa'', "MSF'', "DCF'' or "WWVB'' to indicate the time source.
    
		
    This documentation describes v1.3 (2003/2/21) of the source and has been tested against ntpd 4.1.0 on linux x86. Changes from v1.1 and v1.2 include patches to work with the new ntp-4 code, clock support for DCF and WWVB configurable via mode flag, an option to ignore resync request (for those of us at the fringes of the WWVB signal, for instance), averaging of the signal quality poll and several bug fixes, code cleanup and standardizations. In all other respects, the driver works as per v1.1 if a mode is not specified.
    
		
    To use the alternate modes, the mode flag must be specified. If the mode flag is 0, or unspecified, the original MSF version is assumed. This should assure backwards compatibility and should not break existing setups.
    
		
    The previous documentation described version V1.1 (1997/06/23) of the source and had been tested (amongst others) against ntpd3-5.90 on Solaris-1 (SunOS 4.1.3_U1 on an SS1 serving as a router and firewall) and against ntpd3-5.90 on Solaris-2.5 (on a SS1+ and TurboSPARC 170MHz). That code will claimed increased stability, reduced jitter and more efficiency (fewer context switches) with the tty_clk discipline/STREAMS module installed, but this has not been tested. For a to-do list see the comments at the start of the code.
    
		
    This code has been significantly slimmed down since the V1.0 version, roughly halving the memory footprint of its code and data.
    
		
    This driver is designed to allow the unit to run from batteries as designed, for something approaching the 2.5 years expected in the usual stand-alone mode, but no battery-life measurements have been taken.
    
		
    Much of this code is originally from the other refclock driver files with thanks. The code was originally made to work with the clock by Derek Mulcahy, with modifications by Damon Hart-Davis. Thanks also to Lyndon David for some of the specifications of the clock. Paul Alfille added support for the WWVB clock. Christopher Price added enhanced support for the MSF, DCF and WWVB clocks.
    
		
    There is support for a Tcl/Tk monitor written by Derek Mulcahy that examines the output stats; see the ARC Rugby MSF Receiver page for more details and the code. Information on the WWVB version is available from Atomic Time as their Atomic Time PC.
    
		
    Look at the notes at the start of the code for further information; some of the more important details follow.
    
		
    The driver interrogates the clock at each poll (ie every 64s by default) for a timestamp. The clock responds at the start of the next second (with the start bit of the first byte being on-time). In the default or original MSF mode, the time is in `local' format, including the daylight savings adjustment when it is in effect. The driver code converts the time back to UTC. In modes 1-3 the driver can be configured for UTC or local time depending on the setting of flag1.
    
		
    The clock claims to be accurate to within about 20ms of the broadcast time, and given the low data transmission speed from clock to host, and the fact that the clock is not in continuous sync with MSF, it seems sensible to set the `precision' of this clock to -5 or -4, -4 being used in this code, which builds in a reported dispersion of over 63ms (ie says ``This clock is not very good.''). You can improve the reported precision to -4 (and thus reduce the base dispersion to about 31ms) by setting the fudge flag3 to 1.
    
		
    Even a busy and slow IP link can yield lower dispersions than this from polls of primary time servers on the Internet, which reinforces the idea that this clock should be used as a backup in case of problems with such an IP link, or in the unfortunate event of failure of more accurate sources such as GPS.
    
		
    By default this clock reports itself to be at stratum 2 rather than the usual stratum 0 for a refclock, because it is not really suited to be used as other than a backup source. The stratum reported can be changed with the stratum directive to be whatever you like. After careful monitoring of your clock, and appropriate choice of the time1 fudge factor to remove systematic errors in the clock's reported time, you might fudge the clock to stratum 1 to allow a stratum-2 secondary server to sync to it.
    
		
    In default mode, the driver code arranges to resync the clock to MSF at intervals of a little less than an hour (deliberately avoiding the same time each hour to avoid any systematic problems with the signal or host). Whilst resyncing, the driver supplements the normal polls for time from the clock with polls for the reception signal quality reported by the clock. If the signal quality is too low (0--2 out of a range of 0--5), we chose not to trust the clock until the next resync (which we bring forward by about half an hour). If we don't catch the resync, and so don't know the signal quality, we do trust the clock (because this would generally be when the signal is very good and a resync happens quickly), but we still bring the next resync forward and reduce the reported precision (and thus increase reported dispersion).
    
		
    If we force resyncs to MSF too often we will needlessly exhaust the batteries the unit runs from. During clock resync this driver tries to take enough time samples to avoid ntpd losing sync in case this clock is the current peer. By default the clock would only resync to MSF about once per day, which would almost certainly not be acceptable for NTP purposes.
    
		
    The driver does not force an immediate resync of the clock to MSF when it starts up to avoid excessive battery drain in case ntpd is going to be repeatedly restarted for any reason, and also to allow enough samples of the clock to be taken for ntpd to sync immediately to this clock (and not remain unsynchronised or to sync briefly to another configured peer, only to hop back in a few poll times, causing unnecessary disturbance). This behaviour should not cause problems because the driver will not accept the timestamps from the clock if the status flag delivered with the time code indicates that the last resync attempt was unsuccessful, so the initial timestamps will be close to reality, even if with up to a day's clock drift in the worst case (the clock by default resyncs to MSF once per day).
    
		
    When alternate modes 1-3 are selected, the driver can be configured to ignore the resync requests by setting flag2 to 1. This allows clocks at the fringe of the signal to resync at night when signals are stronger.
    
		
    The clock has a peculiar RS232 arrangement where the transmit lines are powered from the receive lines, presumably to minimise battery drain. This arrangement has two consequences:
    
		
      
			
    • Your RS232 interface must drive both +ve and -ve
			
    • You must (in theory) wait for an echo and a further 10ms between characters
		
    
		
    This driver, running on standard Sun and x86 hardware, seems to work fine; note the use of the send_slow() routine to queue up command characters to be sent once every two seconds.
    
		
    Three commands are sent to the clock by this driver. Each command consists of a single letter (of which only the bottom four bits are significant), followed by a CR (ASCII 13). Each character sent to the clock should be followed by a delay to allow the unit to echo the character, and then by a further 10ms. Following the echo of the command string, there may be a response (ie in the case of the g and o commands below), which in the case of the o command may be delayed by up to 1 second so as the start bit of the first byte of the response can arrive on time. The commands and their responses are:
    
		
    
			
    g CR
			
    Request for signal quality. Answer only valid during (late part of) resync to MSF signal. The response consists of two characters as follows:
					
    
						
    bit 7
						
    parity
						
    bit 6
						
    always 0
						
    bit 5
						
    always 1

    always 1
						
    bit 3
						
    always 0
						
    bit 2
						
    always 0
						
    bit 1
						
    always 1
						
    bit 0
						
    = 0 if no reception attempt at the moment, = 1 if reception attempt (ie resync) in progress
					
    
					
    
						
    bit 7
						
    parity
						
    bit 6
						
    always 0
						
    bit 5
						
    always 1
						
    bit 4
						
    always 1
						
    bit 3
						
    always 0
						
    bit 2--0
						
    reception signal quality in the range 0--5 (very poor to very good); if in the range 0--2 no successful reception is to be expected. The reported value drops to zero when not resyncing, ie when first returned byte is not `3'.
					
    
			
    h CR
			
    Request to resync to signal. Can take up from about 30s to 360s. Drains batteries so should not be used excessively. After this the clock time and date should be correct and the phase within 20ms of time as transmitted from the source signal (remember to allow for propagation time). By default the clock resyncs once per day in the late evening/early morning (presumably to catch transitions to/from daylight saving time quickly). This driver code, by default, resyncs at least once per hour to minimise clock wander.
			
    o CR
			
    Request timestamp. Start bit of first byte of response is on-time, so may be delayed up to 1 second. Note that the driver will convert time to GMT, if required. The response data is as follows:
				
      
					
    1. hours tens (hours range from 00 to 23)
					
    2. hours units
					
    3. minutes tens (minutes range from 00 to 59)
					
    4. minutes units
					
    5. seconds tens (seconds presumed to range from 00 to 60 to allow for leap second)
					
    6. seconds units
					
    7. day of week 1 (Monday) to 7 (Sunday)
					
    8. day of month tens (day ranges from 01 to 31)
					
    9. day of month units
					
    10. month tens (months range from 01 to 12)
					
    11. month units
					
    12. year tens (years range from 00 to 99)
					
    13. year units
					
    14. BST/UTC status (Ignored in WWVB version)

    The driver only accepts time from the clock if the bottom three bits of the status byte are 011 or flag2 is set to 1 to ignore resync requests. For the MSF clock, if the UK parliament decides to move us to +0100/+0200 time as opposed to the current +0000/+0100 time, it is not clear what effect that will have on the time broadcast by MSF, and therefore on this driver's usefulness.
    
		
    
		
    A typical ntp.conf configuration file for this driver might be:

		There are a few #defines in the code that you might wish to play with:
		
    
			
    ARCRON_KEEN
			
    With this defined, the code is relatively trusting of the clock, and assumes that you will have the clock as one of a few time sources, so will bend over backwards to use the time from the clock when available and avoid ntpd dropping sync from the clock where possible. You may wish to undefine this, especially if you have better sources of time or your reception is ropey. However, there are many checks built in even with this flag defined.
			
    ARCRON_MULTIPLE_SAMPLES
			
    When is defined, we regard each character in the returned timecode as at a known delay from the start of the second, and use the smallest (most negative) offset implied by any such character, ie with the smallest kernel-induced display, and use that. This helps to reduce jitter and spikes.
			
    ARCRON_LEAPSECOND_KEEN
			
    When is defined, we try to do a resync to MSF as soon as possible in the first hour of the morning of the first day of the first and seventh months, ie just after a leap-second insertion or deletion would happen if it is going to. This should help compensate for the fact that this clock does not continuously sample MSF, which compounds the fact that MSF itself gives no warning of an impending leap-second event. This code did not seem functional at the leap-second insertion of 30th June 1997 so is by default disabled.
			
    PRECISION
			
    Currently set to -4, but you may wish to set it to -5 if you are more conservative, or to -6 if you have particularly good experience with the clock and you live on the edge. Note that the flag3 fudge value will improve the reported dispersion one notch if clock signal quality is known good. So maybe just leave this alone.
		
    
		
    Monitor Data
    
		
    Each timecode is written to the clockstats file with a signal quality value appended (`0'--`5' as reported by the clock, or `6' for unknown).
    
		
    Each resync and result (plus gaining or losing MSF sync) is logged to the system log at level LOG_NOTICE; note that each resync drains the unit's batteries, so the syslog entry seems justified.
    
		
    Syslog entries are of the form:
    
		
    May 10 10:15:24 oolong ntpd[615]: ARCRON: unit 0: sending resync command
May 10 10:17:32 oolong ntpd[615]: ARCRON: sync finished, signal quality 5: OK, will use clock
May 10 11:13:01 oolong ntpd[615]: ARCRON: unit 0: sending resync command
May 10 11:14:06 oolong ntpd[615]: ARCRON: sync finished, signal quality -1: UNKNOWN, will use clock anyway

May 10 12:41:34 oolong ntpd[615]: ARCRON: sync finished, signal quality 3: OK, will use clock
    
		
    Fudge Factors
    
		
    
		
    
			
    mode 0 | 1 | 2 | 3
			
    Specifies the clock hardware model. This parameter is optional, it defaults to the original mode of operation.
			
    Supported modes of operation:
			
    0 - Default, Original MSF
			
    1 - Updated MSF
			
    2 - New DCF77
			
    3 - New WWVB
			
    time1 time
			
    Specifies the time offset calibration factor, in seconds and fraction, with default 0.0. On a Sun SparcStation 1 running SunOS 4.1.3_U1, with the receiver in London, a value of 0.020 (20ms) seems to be appropriate.
			
    time2 time
			
    Not currently used by this driver.
			
    stratum number
			
    Specifies the driver stratum, in decimal from 0 to 15, with default 2. It is suggested that the clock be not be fudged higher than stratum 1 so that it is used a backup time source rather than a primary when more accurate sources are available.
			
    refid string
			
    Specifies the driver reference identifier, an ASCII string from one to four characters, with default MSFa. When used in modes 1-3, the driver will report either MSF, DCF, or WWVB respectively.
			
    flag1 0 | 1
			
    (Modes 1-3) If set to 0 (the default), the clock is set to UTC time. If set to 1, the clock is set to localtime.
			
    flag2 0 | 1
			
    (Modes 1-3) If set to 0 (the default), the clock will be forced to resync approximately every hour. If set to 1, the clock will resync per normal operations (approximately midnight).
			
    flag3 0 | 1
			
    If set to 1, better precision is reported (and thus lower dispersion) while clock's received signal quality is known to be good.
			
    flag4 0 | 1
			
    Not used by this driver.

    Synopsis
    
		
    Address: 127.127.18.u
    
			Reference ID: NIST | USNO | PTB | WWVB
    
			Driver ID: ACTS_MODEM
    
			Serial Port: /dev/actsu; 9600 baud, 8-bits, no parity

			Requires: /usr/include/sys/termios.h header file with modem control and a dial-out (cua) device.
    
		
    Description
    
		
    This driver supports the US (NIST and USNO) and European (PTB (Germany), NPL (UK), etc.) modem time services, as well as Spectracom GPS and WWVB receivers connected via a modem. The driver periodically dials a number from a telephone list, receives the timecode data and calculates the local clock correction. It is designed primarily for backup when neither a radio clock nor connectivity to Internet time servers are available. It can also be configured to operate full period.
    
		
    For best results the indicated time must be corrected for the modem and telephone circuit propagation delays, which can reach 200 ms or more. For the NIST service, corrections are determined automatically by measuring the roundtrip delay of echoed characters. With this service the absolute accuracy is typically a millisecond or two. Corrections for the other services must be determined by other means. With these services variations from call to call and between messages during a call are typically a few milliseconds, occasionally higher.
    
		
    This driver requires a 9600-bps modem with a Hayes-compatible command set and control over the modem data terminal ready (DTR) control line. The actual line speed ranges from 1200 bps with USNO to 14,400 bps with NIST. The modem setup string is hard-coded in the driver and may require changes for nonstandard modems or special circumstances.
    
		
    There are three modes of operation selected by the mode keyword in the server configuration command. In manual mode (2) the calling program is initiated by setting fudge flag1. This can be done manually using ntpdc, or by a cron job. In auto mode (0) flag1 is set at each poll event. In backup mode (1) flag1 is set at each poll event, but only if no other synchronization sources are available.
    
		
    When flag1 is set, the calling program dials the first number in the list specified by the phone command. If the call fails for any reason, the program dials the second number and so on. The phone number is specified by the Hayes ATDT prefix followed by the number itself, including the prefix and long-distance digits and delay code, if necessary. The flag1 is reset and the calling program terminated if (a) valid clock update has been determined, (b) no more numbers remain in the list, (c) a device fault or timeout occurs or (d) fudge flag1 is reset manually using ntpdc.
    
		
    The driver automatically recognizes the message format of each modem time service. It selects the parsing algorithm depending on the message length. There is some hazard should the message be corrupted. However, the data format is checked carefully and only if all checks succeed is the message accepted. Corrupted lines are discarded without complaint. Once the service is known, the reference identifier for the driver is set to NIST, USNO, PTB or WWVB as appropriate.
    
		
    Ordinarily, the serial port is connected to a modem; however, if fudge flag3 is set, it can be connected directly to a Spectracom WWV or GPS radio for testing or calibration. The Spectracom radio can be connected via a modem if the radio is connfigured to send time codes continuoulsly at 1-s intervals. In principle, fudge flag2 enables port locking, allowing the modem to be shared when not in use by this driver. At least on Solaris with the current NTP I/O routines, this results in lots of ugly error messages.
    
		
    The minpoll and maxpoll keywords of the server configuration command can be used to limit the intervals between calls. The recommended settings are 12 (1.1 hours) for minpoll and 17 (36 hours) for maxpoll. Ordinarily, the poll interval will start at minpoll and ramp up to maxpoll in a day or two.

    If a modem is connected to a Spectracom receiver, this driver will call it and retrieve the time in one of two formats, 0 and 2. Ordinarily, the receiver requires a T in order to return the timecode. As this driver does not send data via the modem, it must either be configured in continuous mode or be polled by another local driver.

    This driver supports a dumb ASCII clock that only emits localtime at a reliable interval. This has no provisions for leap seconds, quality codes, etc. It assumes output in the local time zone, and that the C library mktime()/localtime() routines will correctly convert back and forth between local and UTC.
    
		
    Most of this code is originally from refclock_wwvb.c with thanks. It has been so mangled that wwvb is not a recognizable ancestor.

    Description
    
		
    This driver supports the Heath GC-1000 Most Accurate Clock, with RS232C Output Accessory. This is a WWV/WWVH receiver somewhat less robust than other supported receivers. It's claimed accuracy is 100 ms when actually synchronized to the broadcast signal, but this doesn't happen even most of the time, due to propagation conditions, ambient noise sources, etc. When not synchronized, the accuracy is at the whim of the internal clock oscillator, which can wander into the sunset without warning. Since the indicated precision is 100 ms, expect a host synchronized only to this thing to wander to and fro, occasionally being rudely stepped when the offset exceeds the default CLOCK_MAX of 128 ms.
    
		
    The internal DIPswitches should be set to operate at 1200 baud in MANUAL mode and the current year. The external DIPswitches should be set to GMT and 24-hour format. It is very important that the year be set correctly in the DIPswitches; otherwise, the day of year will be incorrect after 28 April of a normal or leap year.
    
		
    In MANUAL mode the clock responds to a rising edge of the request to send (RTS) modem control line by sending the timecode. Therefore, it is necessary that the operating system implement the TIOCMBIC and TIOCMBIS ioctl system calls and TIOCM_RTS control bit. Present restrictions require the use of a POSIX-compatible programming interface, although other interfaces may work as well.
    
		
    The clock message consists of 23 ASCII printing characters in the following format:
    
		
    hh:mm:ss.f     dd/mm/yr<cr>

hh:mm:ss.f = hours, minutes, seconds
f = deciseconds ('?' when out of spec)
dd/mm/yr = day, month, year
    
		
    The alarm condition is indicated by '?', rather than a digit, at A. Note that 0?:??:??.? is displayed before synchronization is first established and hh:mm:ss.? once synchronization is established and then lost again for about a day.
    
		
    A fudge time1 value of .07 s appears to center the clock offset residuals.

    Shared Memory Driver
    
        
    
        
    Synopsis
    
        
    Address: 127.127.28.u
    
            Reference ID: SHM
    
            Driver ID: SHM
    

        
    Description
    
        
    This driver receives its reference clock info from a shared memory-segment. The shared memory-segment is created with owner-only access for unit 0 and 1, and world access for unit 2 and 3
    

        
    Structure of shared memory-segment
    
        
    struct shmTime {
  int    mode; /* 0 - if valid set
                *       use values, 
                *       clear valid
                * 1 - if valid set 
                *       if count before and after read of 
                *       values is equal,
                *         use values 
                *       clear valid
                */
  int    count;
  time_t clockTimeStampSec;      /* external clock */
  int    clockTimeStampUSec;     /* external clock */
  time_t receiveTimeStampSec;    /* internal clock, when external value was received */
  int    receiveTimeStampUSec;   /* internal clock, when external value was received */
  int    leap;
  int    precision;
  int    nsamples;
  int    valid;
  int    dummy[10]; 
};
    

        
    Operation mode=0
    
        
    Each second, the valid-flag of the shared memory-segment is checked:
    
        
    If set, the values in the record (clockTimeStampSec, clockTimeStampUSec, receiveTimeStampSec, receiveTimeStampUSec, leap, precision) are passed to ntp, and the valid-flag is cleared and a counter is bumped.
    
        
    If not set, a counter is bumped
    
        
    Operation mode=1
    
        
    Each second, the valid-flag of the shared memory-segment is checked:
    
        
    If set, the count-field of the record is remembered, and the values in the record (clockTimeStampSec, clockTimeStampUSec, receiveTimeStampSec, receiveTimeStampUSec, leap, precision) are read. Then, the remembered count is compared to the count now in the record. If both are equal, the values read from the record are passed to ntp. If they differ, another process has modified the record while it was read out (was not able to produce this case), and failure is reported to ntp. The valid flag is cleared and a counter is bumped.
    
        
    If not set, a counter is bumped
    



    gpsd
    

gpsd
knows how to talk to many GPS devices.
It works with ntpd through the SHM driver.

    
The gpsd man page suggests setting minpoll and maxpoll to 4.
That was an attempt to reduce jitter.
The SHM driver was fixed (ntp-4.2.5p138) to collect data each second rather than
once per polling interval so that suggestion is no longer reasonable.

    



    Clockstats
    
If flag4 is set when the driver is polled, a clockstats record is written.
The first 3 fields are the normal date, time, and IP address common to all clockstats records.

    
The 4th field is the number of second ticks since the last poll.
The 5th field is the number of good data samples found.  The last 64 will be used by ntpd.
The 6th field is the number of sample that didn't have valid data ready.
The 7th field is the number of bad samples.
The 8th field is the number of times the the mode 1 info was update while nptd was trying to grab a sample.

    

Here is a sample showing the GPS reception fading out:

		Motorola Oncore GPS Receiver
		
	

	
		
    Motorola Oncore GPS receiver
    
		
    
		
    Synopsis
    
		
    Address: 127.127.30.u
    
			Reference ID: GPS
    
			Driver ID: ONCORE
    
			Serial Port: /dev/oncore.serial.u;  9600 baud, 8-bits, no parity.
    
			PPS Port: /dev/oncore.pps.u;  PPS_CAPTUREASSERT required,  PPS_OFFSETASSERT supported.
    
			Configuration File: ntp.oncore, or ntp.oncore.u, or ntp.oncoreu, in /etc/ntp or /etc.
    
		
    Description
    
		
    This driver supports most models of the Motorola Oncore GPS receivers (Basic, PVT6, VP, UT, UT+, GT, GT+, SL, M12, M12+T), as long as they support the Motorola Binary Protocol.
    
		
    The interesting versions of the Oncore are the VP, the UT+, the "Remote" which is a prepackaged UT+, and the M12 Timing. The VP is no longer available new, and the UT, GT, and SL are at end-of-life. The Motorola evaluation kit can be recommended. It interfaces to a PC straightaway, using the serial (DCD) or parallel port for PPS input and packs the receiver in a nice and sturdy box. Less expensive interface kits are available from TAPR and Synergy.

    The driver requires a standard PPS interface for the pulse-per-second output from the receiver. The serial data stream alone does not provide precision time stamps (0-50msec variance, according to the manual), whereas the PPS output is precise down to 50 nsec (1 sigma) for the VP/UT models and 25 nsec for the M12 Timing. If you do not have the PPS signal available, then you should probably be using the NMEA driver rather than the Oncore driver. Most of these are available on-line
    
		
    The driver will use the "position hold" mode with user provided coordinates, the receivers built-in site-survey, or a similar algorithm implemented in this driver to determine the antenna position.
    
		
    Monitor Data
    
		The driver always puts a lot of useful information on the clockstats file, and when run with debugging can be quite chatty on stdout. When first starting to use the driver you should definitely review the information written to the clockstats file to verify that the driver is running correctly.
		
    In addition, on platforms supporting Shared Memory, all of the messages received from the Oncore receiver are made available in shared memory for use by other programs. See the Oncore-SHMEM manual page for information on how to use this option. For either debugging or using the SHMEM option, an Oncore Reference Manual for the specific receiver in use will be required.

    Additional Information
    
		
    The driver was initially developed on FreeBSD, and has since been tested on Linux, SunOS and Solaris.
    
		
    Configuration
    
		
    There is a driver specific configuration file ntp.oncore (or ntp.oncore.u or ntp.oncoreu if you must distinguish between more than one Oncore receiver) that contains information on the startup mode, the location of the GPS receiver, an offset of the PPS signal from zero, and the cable delay. The offset shifts the PPS signal to avoid interrupt pileups `on' the second, and adjusts the timestamp accordingly. See the driver source for information on this file. The default with no file is: no delay, no offset, and a site survey is done to get the location of the gps receiver.
    
		
    The following three options can be set in the driver specific configuration file only if the driver is using the PPSAPI. The edge of the PPS signal that is `on-time' can be set with the keywords [ASSERT/CLEAR] and the word HARDPPS will cause the PPS signal to control the kernel PLL.
    
		
    Performance
    
		
    Really good. With the VP/UT+, the generated PPS pulse is referenced to UTC(GPS) with better than 50 nsec (1 sigma) accuracy. The limiting factor will be the timebase of the computer and the precision with which you can timestamp the rising flank of the PPS signal. Using FreeBSD, a FPGA based Timecounter/PPS interface, and an ovenized quartz oscillator, that performance has been reproduced. For more details on this aspect: Sub-Microsecond timekeeping under FreeBSD.

    Description
    
		The refclock_neoclock4x driver supports the NeoClock4X receiver available from Linum Software GmbH. The receiver is available as a DCF77 or TDF receiver. Both receivers have the same output string. For more information about the NeoClock4X receiver please visit http://www.linux-funkuhr.de.  
		
    
		
    Fudge Factors
    
		
    
			
    time1 time
			
    Specifies the time offset calibration factor with the default value off 0.16958333 seconds. This offset is used  to correct serial line and operating system delays incurred in capturing time stamps. If you want to fudge the time1 offset ALWAYS add a value off 0.16958333. This is neccessary to compensate to delay that is caused by transmit the timestamp at 2400 Baud. If you want to compensate the delay that the DCF77 or TDF radio signal takes to travel to your site simply add the needed millisecond delay to the given value. Note that the time here is given in seconds.
			
    Default setting is 0.16958333 seconds.
    
		
    
		
    
			
    time2 time
			
    Not used by this driver.
		
    
		
    
			
    flag1 0 | 1
			
    When set to 1 the driver will feed ntp with timestampe even if the radio signal is lost. In this case an internal backup clock generates the timestamps. This is ok as long as the receiver is synced once since the receiver is able to keep time for a long period.
			
    Default setting is 0 = don't synchronize to CMOS clock.
			
    flag2 0 | 1
			
    You can allow the NeoClock4X driver to use the quartz clock even if it is never synchronized to a radio clock. This is usally not a good idea if you want preceise timestamps since the CMOS clock is maybe not adjusted to a dst status change. So PLEASE switch this only on if you now what you're doing.
			
    Default setting is 0 = don't synchronize to unsynchronized CMOS clock.
			
    flag3 0 | 1
			
    Not used by this driver.
			
    flag4 0 | 1
			
    It is recommended to allow extensive logging while you setup the NeoClock4X receiver. If you activate flag4 every received data is logged. You should turn off flag4 as soon as the clock works as expected to reduce logfile cluttering.
			
    Default setting is 0 = don't log received data and converted utc time.

    RIPE NCC interface for Trimble Palisade
    
		
    
		Trimble Acutime 2000
		
    Synopsis
    
		Address: 127.127.43.u
    
		Reference ID: RIPENCC
    
		Driver ID: RIPENCC
		
    Description
    
		
    This is a special driver developed to be used in conjuction with the RIPE NCC clock card in the RIPE NCC Test Traffic Measurements project.
    
		
    Why this driver?
    
		
    The reason why we created a seperated driver for an antenna for which already a (vendor supplied) driver exist is a design decision. To be more specific, the standard Trimble interface uses a 12 pin connector. The cable sold by Trimble to connect to this wire is a very thick cable. Certainly not something you wish to run for several 100 meters through your building. And if you wanted to run it for 100 meters, you always would have to really run the cable, and didn't have the option to use existing wiring.
    
		
    
		
    This is where we wanted more flexibility. We wanted to be able to use existing wiring in buildings. That leaded us to CAT-5(UTP) which only gives us 8 wires. Therefor we decided to redesing the use of the Trimble antenna. The Trimble supports two modes: EVENT driver and PPS mode. The default is to use the EVENT mode which needs all 12 wires. We only use the PPS timestamps for which we have enough with 8 wires. For our purposes this is more than fine.
    
		More information about the project can be found on the Test Traffic Measurements website. RIPE NCC clock card
		
    RIPE NCC clock card
    
		
    The card is very a simple PCI card. The only feature on the bus it uses is the power supply. It uses this power supply to power the Trimble GPS antenna.
    
		
    The card basicly just is a RS422 to RS232 converter. It gets the Trimble's RS422 signal on a RJ45 connector and transforms that to RS232 on a DIN9 connector. This connector should be loopbacked on the back of the machine to the serial port. As said, the card doesn't do any PCI data transfers.

    PSTI/Traconex 1020 WWV/WWVH Receiver
    
		
    
		
    Synopsis
    
		
    Address: 127.127.3.u
    
			Reference ID: WWV
    
			Driver ID: WWV_PST
    
			Serial Port: /dev/wwvu; 9600 baud, 8-bits, no parity
    
			Features: tty_clk
    
		
    Description
    
		
    This driver supports the PSTI 1010 and Traconex 1020 WWV/WWVH Receivers. No specific claim of accuracy is made for these receiver, but actual experience suggests that 10 ms would be a conservative assumption.
    
		
    The dipswitches should be set for 9600 bps line speed, 24-hour day-of-year format and UTC time zone. Automatic correction for DST should be disabled. It is very important that the year be set correctly in the DIP-switches; otherwise, the day of year will be incorrect after 28 April of a normal or leap year. As the there are only four dipswitches to set the year and the base value of zero correspondes to 1986, years beyond 2001 recycle with the value of zero corresponding to 2002. The propagation delay DIP-switches should be set according to the distance from the transmitter for both WWV and WWVH, as described in the instructions. While the delay can be set only to within 11 ms, the fudge time1 parameter can be used for vernier corrections.
    
		
    Using the poll sequence QTQDQM, the response timecode is in three sections totalling 50 ASCII printing characters, as concatenated by the driver, in the following format:
    
		
    ahh:mm:ss.fffs<cr> yy/dd/mm/ddd<cr>
frdzycchhSSFTttttuuxx<cr>

on-time = first <cr>
hh:mm:ss.fff = hours, minutes, seconds, milliseconds
a = AM/PM indicator (' ' for 24-hour mode)
yy = year (from DIPswitches)
dd/mm/ddd = day of month, month, day of year
s = daylight-saving indicator (' ' for 24-hour mode)
f = frequency enable (O = all frequencies enabled)
r = baud rate (3 = 1200, 6 = 9600)
d = features indicator (@ = month/day display enabled)
z = time zone (0 = UTC)
y = year (5 = 91)
cc = WWV propagation delay (52 = 22 ms)
hh = WWVH propagation delay (81 = 33 ms)
SS = status (80 or 82 = operating correctly)
F = current receive frequency (4 = 15 MHz)
T = transmitter (C = WWV, H = WWVH)
tttt = time since last update (0000 = minutes)
uu = flush character (03 = ^c)
xx = 94 (unknown)
    
		
    The alarm condition is indicated by other than 8 at a, which occurs during initial synchronization and when received signal is lost for an extended period; unlock condition is indicated by other than 0000 in the tttt subfield.

    Rockwell Jupiter GPS receiver
    
		
    
		
    Synopsis
    
		
    Address: 127.127.31.u
    
			Reference ID: GPS
    
			Driver ID: JUPITER
    
			Serial Port: /dev/gpsu;  9600 baud, 8-bits, no parity.
    
		
    Description
    
		
    This driver supports at least some models of the Rockwell Jupiter GPS receivers (Jupiter 11, Jupiter-T), they must at least support the Zodiac Binary Protocol.
    
		
    The driver requires a standard PPS interface for the pulse-per-second output from the receiver. The serial data stream alone does not provide precision time stamps, whereas the PPS output is precise down to 40 ns (1 sigma) for the Jupiter 11 and 25 ns (1 sigma) for Jupiter-T according to the documentation. If you do not have the PPS signal available, then you should probably not be using the Jupiter receiver as a time source. This driver requires a PPS signal and the time output from Jupiter receivers is not predictable in NMEA mode; the reported time can take one second steps.
    
		
    Monitor Data
    
		
    The driver always puts a lot of useful information on the clockstats file, and when run with debugging can be quite chatty on stdout. When first starting to use the driver you should definitely review the information written to the clockstats file to verify that the driver is running correctly.

    Not used by this driver.
		
    
		
    Additional Information
    
		
    The driver was resurrected from a sorry state using the Windows NT port and a Jupiter 11, and has since seen little testing on other platforms. On Windows there exist a barrier though, as there is no publicly available PPSAPI implementation, at least not to my knowledge. However, there has been one success report using Linux 2.4.20 and PPSkit 2.1.1.
    
		
    The Jupiter receivers seem to have quite a few names. They are referred to at least as Rockwell receivers, Navman receivers, Zodiac receivers, Conexant receivers and SiRF Technology receivers. Rockwell seems to be the original and most commonly used name and Navman seems to be the current supplier.
    
		
    Configuration
    
		
    The edge of the PPS signal that is `on-time' can be set with flag2. There is currently no way to cause the PPS signal to control the kernel PLL.
    
		
    Performance
    
		
    The performance is largely unexplored. I have achieved submillisecond stability using a Jupiter 11, but the poor result is more than likely due to the proprietary PPSAPI implementation or Windows itself.
    
		
    This driver does not handle leap seconds.

Last update:

    Synopsis
    


    Address: 127.127.4.u
    
Reference ID: WWVB
    
Driver ID: WWVB_SPEC
    
Serial Port: /dev/wwvbu; 9600 baud, 8-bits, no parity
    
Features: Optional PPS signal processing, tty_clk
    
Requires: Optional PPS signal processing requires the PPSAPI signal interface.
    


    Description
    


    This driver supports all known Spectracom radio and satellite clocks, including the Model 8170 and Netclock/2 WWVB Synchronized Clocks and the Netclock/GPS GPS Master Clock. The claimed accuracy of the WWVB clocks is 100 ms relative to the broadcast signal. These clocks have proven a reliable source of time, except in some parts of the country with high levels of conducted RF interference. WIth the GPS clock the claimed accuracy is 130 ns. However, in most cases the actual accuracy is limited by the precision of the timecode and the latencies of the serial interface and operating system.
    


    The DIPswitches on these clocks should be set to 24-hour display, AUTO DST off, data format 0 or 2 (see below) and baud rate 9600. If this clock is used as the source for the IRIG Audio Decoder (refclock_irig.c in this distribution), set the DIPswitches for AM IRIG output and IRIG format 1 (IRIG B with signature control).
    


    There are two timecode formats used by these clocks. Format 0, which is available with all clocks, and format 2, which is available with all clocks except the original (unmodified) Model 8170.
    


    Format 0 (22 ASCII printing characters):
    
<cr><lf>i ddd hh:mm:ss TZ=zz<cr><lf>
    


    on-time = first <cr>
    
i = synchronization flag (' ' = in synch, '?' = out synch)
    
hh:mm:ss = hours, minutes, seconds
    


    The alarm condition is indicated by other than ' ' at i, which occurs during initial synchronization and when received signal is lost for about ten hours.
    


    Format 2 (24 ASCII printing characters):
    
lt;cr>lf>iqyy ddd hh:mm:ss.fff ld
    


    on-time = <cr>
    
i = synchronization flag (' ' = in synch, '?' = out synch)
    
q = quality indicator (' ' = locked, 'A'...'D' = unlocked)
    
yy = year (as broadcast)
    
ddd = day of year
    
hh:mm:ss.fff = hours, minutes, seconds, milliseconds
    


    The alarm condition is indicated by other than ' ' at i, which occurs during initial synchronization and when received signal is lost for about ten hours. The unlock condition is indicated by other than ' ' at q.
    


    The q is normally ' ' when the time error is less than 1 ms and a character in the set A...D when the time error is less than 10, 100, 500 and greater than 500 ms respectively. The l is normally ' ', but is set to L early in the month of an upcoming UTC leap second and reset to ' ' on the first day of the following month. The d is set to S for standard time S, I on the day preceding a switch to daylight time, D for daylight time and O on the day preceding a switch to standard time. The start bit of the first <cr> is synchronized to the indicated time as returned.
    


    This driver does not need to be told which format is in use - it figures out which one from the length of the message. A three-stage median filter is used to reduce jitter and provide a dispersion measure. The driver makes no attempt to correct for the intrinsic jitter of the radio itself, which is a known problem with the older radios.
    




    When PPS signal processing is enabled, and when the system clock has been set by this or another driver and the PPS signal offset is within 0.4 s of the system clock offset, the PPS signal replaces the timecode for as long as the PPS signal is active. If for some reason the PPS signal fails for one or more poll intervals, the driver reverts to the timecode. If the timecode fails for one or more poll intervals, the PPS signal is disconnected.
    


    Monitor Data
    


    The driver writes each timecode as received to the clockstats file. When enabled by the flag4 fudge flag, a table of quality data maintained internally by the Netclock/2 is retrieved and written to the clockstats file when the first timecode message of a new day is received.

    Synopsis
    


    Address: 127.127.22.u
    
Reference ID: PPS
    
Driver ID: PPS
    
Serial or Parallel Port: /dev/ppsu
    
Requires: PPSAPI signal interface for PPS signal processing.
    


    Note: This driver supersedes an older one of the same name. The older driver operated with several somewhat archaic signal interface devices, required intricate configuration and was poorly documented. This driver requires the Pulse per Second API (PPSAPI)1.	Note also that the pps configuration command has been obsoleted by this driver.
    


    Description
    


    This driver furnishes an interface for the pulse-per-second (PPS) signal produced by a cesium clock, radio clock or related devices. It can be used to augment the serial timecode generated by a GPS receiver, for example. It can be used to remove accumulated jitter and re-time a secondary server when synchronized to a primary server over a congested, wide-area network and before redistributing the time to local clients. The driver includes extensive signal sanity checks and grooming algorithms. A range gate and frequency discriminator reject noise and signals with incorrect frequency. A multiple-stage median filter rejects jitter due to hardware interrupt and operating system latencies. A trimmed-mean algorithm determines the best time samples. With typical workstations and processing loads, the incidental jitter can be reduced to a few microseconds.
    


    While this driver can discipline the time and frequency relative to the PPS source, it cannot number the seconds. For this purpose an auxiliary source is required, ordinarily a radio clock operated as a primary reference (stratum 1) source; however, another NTP time server can be used as well. For this purpose, the auxiliary source should be specified as the prefer peer, as described in the Mitigation Rules and the prefer Keyword page.
    
		
    The driver requires the PPSAPI interface1, which is a proposed IETF standard. The interface consists of the timepps.h header file and associated kernel support. Support for this interface is included in current versions of Solaris, FreeBSD and Linux and proprietary versions of Tru64 (Alpha) and SunOS. See the Pulse-per-second (PPS) Signal Interfacing page for further information.
    
		
    The PPS source can be connected via a serial or parallel port, depending on the hardware and operating system. A serial port can be dedicated to the PPS source or shared with another device; however, if dedicated the data leads should not be connected, as noise or unexpected signals can cause ntpd to exit.
    
		
    A radio clock is usually connected via a serial port and the PPS source
			connected via a level converter to the data carrier detect (DCD)
			pin (DB-9 pin 1, DB-25 pin 8) of the same connector. In some systems
			where a parallel port and driver are available, the PPS signal can
			be connected directly to the ACK pin (DB25 pin 10) of the connector.
			Whether the PPS signal is connected via a dedicated port or shared with another
			device, the driver opens the device /dev/pps%d,
			where %d is the unit number. As with other drivers, links can be
			used to redirect the logical name to the actual physical device.
    
		
    The driver normally operates like any other driver and uses the same mitigation
			algorithms and PLL/FLL clock discipline incorporated in the daemon.
			If kernel PLL/FLL support is available, the kernel PLL/FLL clock
			discipline can be used instead. The default behavior is not to use
			the kernel PPS clock discipline, even if present. This driver incorporates
			a good deal of signal processing to reduce jitter using the median
			filter algorithm in the driver. As the result, performance
			with minpoll  configured at  4 (16s) is generally
			better than the kernel PPS discipline. However, fudge flag 3 can
			be used to enable the kernel PPS discipline if necessary.
    
	
    This driver 
		is enabled only under one of two conditions (a) a prefer peer other than
		this  driver is among the survivors of the mitigation algorithms or (b)
		there are no survivors and the minsane option
		of the tos command is 0. The prefer peer designates another source
		that can reliably number the seconds when available . However, if no
		sources are available, the system clock continues to be disciplined by
		the PPS driver on an indefinite basis.
    
		
    A scenario where the latter behavior can be most useful is a planetary orbiter
			fleet, for instance in the vicinity of Mars, where contact between orbiters
			and Earth only one or two times per Sol (Mars day). These orbiters have a
			precise timing reference based on an Ultra Stable Oscillator (USO) with accuracy
			in the order of a Cesium oscillator. A PPS signal is derived from the USO
			and can be disciplined from Earth on rare occasion or from another orbiter
			via NTP. In the above scenario the PPS signal disciplines the spacecraft clock
			between NTP updates.
    
		
    In a similar scenario a PPS signal can be used to discipline the clock between
			updates produced by the modem driver. This would provide precise synchronization
			without needing the Internet at all.

    Radio CHU Audio Demodulator/Decoder
    
		
    
		
    Synopsis
    
			Address: 127.127.7.u
    
			Reference ID: CHU
    
			Driver ID: CHU
    
			Modem Port: /dev/chuu; 300 baud, 8-bits, no parity
    
			Autotune Port: /dev/icom; 1200/9600 baud, 8-bits, no parity
    
			Audio Device: /dev/audio and /dev/audioctl
		
    Description
    
		
    This driver synchronizes the computer time using shortwave radio transmissions
			from Canadian time/frequency station CHU in
			Ottawa, Ontario. CHU transmissions are made continuously on 3.330,
			7.850 and 14.670 MHz in upper sideband, compatible AM mode. An ordinary
			shortwave receiver can be tuned manually to one of these frequencies or, in
			the case of ICOM receivers, the receiver can be tuned automatically as propagation
			conditions change throughout the day and season.
    
		
    The driver can be compiled to use either an audio codec or soundcard, or a Bell 103-compatible, 300-b/s modem or modem chip, as described on the Pulse-per-second (PPS) Signal Interfacing page. If compiled for a modem, the driver uses it to receive the radio signal and demodulate the data. If compiled for the audio codec, it requires a sampling rate of 8 kHz and m-law companding to demodulate the data. This is the same standard as used by the telephone industry and is supported by most hardware and operating systems, including Solaris, FreeBSD and Linux, among others. The radio is connected via an optional attenuator and cable to either the microphone or line-in port of a workstation or PC. In this implementation, only one audio driver and codec can be supported on a single machine.
    
		
    In general and without calibration, the driver is accurate within 1 ms relative to the broadcast time when tracking a station. However, variations up to 0.3 ms can be expected due to diurnal variations in ionospheric layer height and ray geometry. In Newark DE, 625 km from the transmitter, the predicted one-hop propagation delay varies from 2.8 ms in sunlight to 2.6 ms in moonlight. When not tracking the station the accuracy depends on the computer clock oscillator stability, ordinarily better than 0.5 PPM.
    
		
    After calibration relative to the PPS signal from a GPS receiver, the mean offset with a 2.4-GHz P4 running FreeBSD 6.1 is generally within 0.2 ms short-term with 0.4 ms jitter. The long-term mean offset varies up to 0.3 ms due to propagation path geometry variations. The processor load due to the driver is 0.4 percent on the P4.
    
		
    The driver performs a number of error checks to protect against overdriven or underdriven input signal levels, incorrect signal format or improper hardware configuration. The specific checks are detailed later in this page. Note that additional checks are done elsewhere in the reference clock interface routines.
    
		
    This driver incorporates several features in common with other audio drivers such as described in the Radio WWV/H Audio Demodulator/Decoder and the IRIG Audio Decoder pages. They include automatic gain control (AGC), selectable audio codec port and signal monitoring capabilities. For a discussion of these common features, as well as a guide to hookup, debugging and monitoring, see the Reference Clock Audio Drivers page.
    
		
    Technical Overview
    
		
    The driver processes 8-kHz m-law companded codec samples using maximum-likelihood techniques which exploit the considerable degree of redundancy available in each broadcast message or burst. As described below, every character is sent twice and, in the case of format A bursts, the burst is sent eight times every minute. The single format B burst is considered correct only if every character matches its repetition in the burst. For the eight format A bursts, a majority decoder requires more than half of the 16 repetitions for each digit decode to the same value. Every character in every burst provides an independent timestamp upon arrival with a potential total of 60 timestamps for each minute.
    
		
    The CHU timecode format is described on the CHU website. A timecode is assembled when all bursts have been received in each minute. The timecode is considered valid and the clock set when at least one valid format B burst has been decoded and the majority decoder declares success. Once the driver has synchronized for the first time, it will appear reachable and selectable to discipline the system clock. It is normal on occasion to miss a minute or two due to signal fades or noise. If eight successive minutes are missed, the driver is considered unreachable and the system clock will free-wheel at the latest determined frequency offset. Since the signals are almost always available during some period of the day and the NTP clock discipline algorithms are designed to work well even with long intervals between updates, it is unlikely that the system clock will drift more than a few milliseconds during periods of signal loss.
    
		
    Baseband Signal Processing
    
		
    The program consists of four major parts: the DSP modem, maximum-likelihood UART, burst assembler and majority decoder. The DSP modem demodulates Bell 103 modem answer-frequency signals; that is, frequency-shift keyed (FSK) tones of 2225 Hz (mark) and 2025 Hz (space). It consists of a 500-Hz bandpass filter centered on 2125 Hz followed by a limiter/discriminator and raised-cosine lowpass filter optimized for the 300-b/s data rate. 
    
		
    The maximum likelihood UART is implemented using a set of eight 11-stage shift registers, one for each of eight phases of the 300-b/s bit clock. At each phase a new baseband signal from the DSP modem is shifted into the corresponding register and the maximum and minimum over all 11 samples computed. This establishes a span (difference) and slice level (average) over all 11 stages. For each stage, a signal level above the slice is a mark (1) and below that is a space (0). A quality metric is calculated for each register with respect to the slice level and the a-priori signal consisting of a start bit (space), eight arbitrary information bits and two stop bits (mark).
    
		
    The shift registers are processed in round-robin order as the phases of each bit arrive. At the end of each bit all eight phases are searched for valid framing bits, sufficient span and best metric. The best candidate found in this way represents the maximum-likelihood character. The process then continues for all ten characters in the burst.
    
		
    The burst assembler processes characters either from the maximum-likelihood UART or directly from the serial port as configured. A burst begins when a character is received and is processed after a timeout interval when no characters are received. If the interval between characters is greater than two characters, but less than the timeout interval, the burst is rejected as a runt and a new burst begun. As each character is received, a timestamp is captured and saved for later processing.
    
		
    A valid burst consists of ten characters in two replicated five-character blocks, each block representing ten 4-bit BCD digits. The format B blocks sent in second 31 contain the year and other information in ten digits. The eight format A blocks sent in seconds 32-39 contain the timecode in ten digits, the first of which is a framing code (6). The burst assembler must deal with cases where the first character of a format A burst is lost or is noise. This is done using the framing codes to correct the discrepancy, either one character early or one character late.
    
		
    The burst distance is incremented by one for each bit in the first block that matches the corresponding bit in the second block and decremented by one otherwise. In a format B burst the second block is bit-inverted relative to the first, so a perfect burst of five 8-bit characters has distance -40. In a format A burst the two blocks are identical, so a perfect burst has distance +40. Format B bursts must be perfect to be acceptable; however, format A bursts, which are further processed by the majority decoder, are acceptable if the distance is at least 28.
    
		
    Majority Decoder
    
		
    Each minute of transmission includes eight format A bursts containing two timecodes for each second from 32 through 39. The majority decoder uses a decoding matrix of ten rows, one for each digit position in the timecode, and 16 columns, one for each 4-bit code combination that might be decoded at that position. In order to use the character timestamps, it is necessary to reliably determine the second number of each burst. In a valid burst, the last digit of the two timecodes in the burst must match and the value must be in the range 2-9 and greater than in the previous burst.
    
		
    As each digit of a valid burst is processed, the value at the row corresponding to the digit position in the timecode and column corresponding to the code found at that position is incremented. At the end of the minute, each row of the decoding matrix encodes the number of occurrences of each code found at the corresponding position.
    
		
    The maximum over all occurrences at each digit position is the distance for that position and the corresponding code is the maximum-likelihood digit. If the distance is not more than half the total number of occurrences, the decoder assumes a soft error and discards all information collected during the minute. The decoding distance is defined as the sum of the distances over the first nine digits; the tenth digit varies over the seconds and is uncounted.
    
		
    The result of the majority decoder is a nine-digit timecode representing the maximum-likelihood candidate for the transmitted timecode in that minute. Note that the second and fraction within the minute are always zero and that the actual reference point to calculate timestamp offsets is backdated to the first second of the minute. At this point the timecode block is reformatted and the year, days, hours and minutes extracted along with other information from the format B burst, including DST state, DUT1 correction and leap warning. The reformatting operation checks the timecode for invalid code combinations that might have been left by the majority decoder and rejects the entire timecode if found.
    
		
    If the timecode is valid, it is passed to the reference clock interface along with the backdated timestamps accumulated over the minute. A perfect set of eight bursts could generate as many as 80 timestamps, but the maximum the interface can handle is 60. These are processed using a median filter and trimmed-mean average, so the resulting system clock correction is usually much better than would otherwise be the case with radio noise, UART jitter and occasional burst errors.
    
		
    Autotune
    
		
    The driver includes provisions to automatically tune the radio in response to changing radio propagation conditions throughout the day and night. The radio interface is compatible with the ICOM CI-V standard, which is a bidirectional serial bus operating at TTL levels. The bus can be connected to a standard serial port using a level converter such as the CT-17. Further details are on the Reference Clock Audio Drivers page.
    
		
    If specified, the driver will attempt to open the device /dev/icom and, if successful will tune the radio to 3.331 MHz. The 1-kHz offset is useful with a narrowband SSB filter where the passband includes the carrier and modem signals. However, the driver is liberal in what it assumes of the configuration. If the /dev/icom link is not present or the open fails or the CI-V bus is inoperative, the driver continues in single-frequency mode.
    
		
    As long as no bursts are received, the driver cycles over the three frequencies in turn, one minute for each station. When bursts are received from one or more stations, the driver operates in a five-minute cycle. During the first four minutes it tunes to the station with the highest metric. During the last minute it alternates between the other two stations in turn in order to measure the metric.
    
		
    Debugging Aids
    
		
    The most convenient way to track the program status is using the ntpq program and the clockvar command. This displays the last determined timecode and related status and error counters, even when the program is not discipline the system clock. If the debugging trace feature (-d on the ntpd command line) is enabled, the program produces detailed status messages as it operates. If the fudge flag 4 is set, these messages are written to the clockstats file. All messages produced by this driver have the prefix chu for convenient filtering with the Unix grep command.
    
		
    With debugging enabled the driver produces messages in the following formats: A single message beginning with chuB is produced for each format B burst received in second 31, while eight messages beginning with chuA are produced for each format A burst received in seconds 32 through 39 of the minute. The first four fields are
    
		
    stat sig n b
    
		
    where stat is the status code, sig the character span, n the number of characters in the burst (9-11) and b the burst distance (0-40). Good bursts will have spans of a 800 or more and the other numbers near the top of the range specified. See the source for the interpretation of the remaining data in the burst. Note that each character of the burst is encoded as two digits in nibble-swapped order.
    
		
    If the CI-V interface for ICOM radios is active, a debug level greater than 1 will produce a trace of the CI-V command and response messages. Interpretation of these messages requires knowledge of the CI-V protocol, which is beyond the scope of this document.
    
		
    Monitor Data
    
			When enabled by the filegen facility, every received timecode is written to the clockstats file in the following format:
            sq yyyy ddd hh:mm:ss lw dst du lset agc rfrq bcnt dist tsmp

        s       sync indicator
        q       quality character
        yyyy    Gregorian year
        ddd     day of year
        hh      hour of day
        mm      minute of hour
        ss      second of minute
        lw      leap second warning
        dst     DST state
        dut     DUT sign and magnitude in deciseconds
        lset    minutes since last set
        agc     audio gain (0-255)
        ident   CHU identifier code
        dist    decoder distance
        tsmp    timestamps captured

    
			The fields beginning with year and extending through dut are decoded from the received data and are in fixed-length format. The agc and lset fields, as well as the following driver-dependent fields, are in variable-length format.
		
    
			
    s
			
    The sync indicator is initially ? before the clock is set, but turns to space when the clock has been correctly set.
			
    q
			
    The quality character is a four-bit hexadecimal code showing which alarms have been raised during the most recent minute. Each bit is associated with a specific alarm condition according to the following:
				
    
					
    8
					
    Timestamp alarm. Fewer than 20 timestamps have been determined.
					
    4
					
    Decoder alarm. A majority of repetitions for at least one digit of the timecode fails to agree.
					
    2
					
    Format alarm. One or more bursts contained invalid data or was improperly formatted.
    1
					
    Frame alarm. One or more bursts was improperly framed or  contained too many repetition errors.
    
				
    The timestamp and decoder alarms are fatal; the data accumulated during the minute are not used to set the clock. The format and fram alarm are nonfatal; only the data in the burst are discarded.
    
			
				
			
			
    yyyy ddd hh:mm:ss
			
    The timecode format itself is self explanatory. Note that the Gregorian year is decoded directly from the transmitted timecode.
			
			
    lw
			
    The leap second warning is normally space, but changes to L if a leap second is to occur at the end of the month.
    dst
			
    The DST code for Canada encodes the state for all provinces. It is encoded as two hex characters.
			
    dut
			
    The DUT sign and magnitude shows the current UT1 offset relative to the displayed UTC time, in deciseconds. It is encoded as one digit preceeded by sign.
			
    lset
			
    Before the clock is set, this is the number of minutes since the program was started; after the clock is set, this is the number of minutes since the time was last verified relative to the broadcast signal.
    agc
			
    The audio gain shows the current codec gain setting in the range 0 to 255. Ordinarily, the receiver audio gain control should be set for a value midway in this range.
			
    ident
			
    The CHU identifier CHU followed by the current radio frequency
				code, if the CI-V interface is active, or CHU if not. The radio
				frequncy is encoded as 0 for 3.330 MHz, 1 for 7.850 MHz and 2
				for 14.670 MHz.
    dist
			
    The decoding distance determined during the most recent minute bursts were received. The values range from 0 to 160, with the higher values indicating better signals. The decoding algorithms require the distance at least 50; otherwise all data in the minute are discarded.
    tsmp
			
    The number of timestamps determined during the most recent minute bursts were received. The values range from 0 to 60, with the higher values indicating better signals. The decoding algoriths require at least 20 timestamps in the minute; otherwise all data in the minute are discarded.
		
    
		
    Fudge Factors

    flag1 0 | 1
			
    Not used by this driver.
			
			
    flag2 0 | 1
			
    When the audio driver is compiled, this flag selects the audio input port, where 0 is the mike port (default) and 1 is the line-in port. It does not seem useful to select the compact disc player port.
			
			
    flag3 0 | 1
			
    When the audio driver is compiled, this flag enables audio monitoring of the input signal. For this purpose, the speaker volume must be set before the driver is started.
			
			
    flag4 0 | 1
			
    Enable verbose clockstats recording if set.

    Operating Modes
    
		
    This driver supports two modes of operation, static and mobile, controlled by clock flag 2.
    
		
    In static mode (the default) the driver assumes that the GPS antenna is in a fixed location. The receiver is initially placed in a "Static, 3D Nav" mode, where latitude, longitude, elevation and time are calculated for a fixed station. An average position is calculated from this data. After 24 hours, the receiver is placed into a "Known Position" mode, initialized with the calculated position, and then solves only for time.
    
		
    In mobile mode, the driver assumes the GPS antenna is mounted on a moving platform such as a car, ship, or aircraft. The receiver is placed in "Dynamic, 3D Nav" mode and solves for position, altitude and time while moving. No position averaging is performed.
    
		
    Monitor Data
    
		
    The driver writes each timecode as received to the clockstats file. Documentation for the NMEA-0183 proprietary sentences produced by the MX4200 can be found in MX4200 Receiver Data Format.

		IRIG Audio Decoder
		
	
	
		
    IRIG Audio Decoder
    
		
    
		
    Synopsis
    
			Address: 127.127.6.u
    
			Reference ID: IRIG
    
			Driver ID: IRIG_AUDIO
    
			Audio Device: /dev/audio and /dev/audioctl
		
    Description
    
		
    This driver synchronizes the computer time using the Inter-Range Instrumentation Group (IRIG) standard time distribution signal. This signal is generated by several radio clocks, including those made by Arbiter, Austron, Bancomm, Odetics, Spectracom, Symmetricom and TrueTime, among others, although it is often an add-on option. The signal is connected via an optional attenuator and cable to either the microphone or line-in port of a workstation or PC.
    
		
    The driver requires an audio codec or sound card with sampling rate 8 kHz and m-law companding to demodulate the data. This is the same standard as used by the telephone industry and is supported by most hardware and operating systems, including Solaris, FreeBSD and Linux, among others. In this implementation, only one audio driver and codec can be supported on a single machine. In order to assure reliable signal capture, the codec frequency error must be less than 250 PPM (.025 percent). If necessary, the tinker codec configuration command can be used to bracket the codec frequency to this range.
    
		
    For proper operation the IRIG signal source should be configured for analog signal levels, not digital TTL levels. In most radios the IRIG signal is driven ±10 V behind 50 Ohms. In such cases the cable should be terminated at the line-in port with a 50-Ohm resistor to avoid overloading the codec. Where feasible, the IRIG signal source should be operated with signature control so that, if the signal is lost or mutilated, the source produces an unmodulated signal, rather than possibly random digits. The driver automatically rejects the data and declares itself unsynchronized in this case. Some devices, in particular Spectracom radio/satellite clocks, provide additional year and status indication; other devices may not.
    
		
    In general and without calibration, the driver is accurate within 500 ms relative to the IRIG time. After calibrating relative to the PPS signal from a GPS receiver, the mean offset with a 2.4-GHz P4 running FreeBSD 6.1 is less than 20 ms with standard deviation 10 ms. Most of this is due to residuals after filtering and averaging the raw codec samples, which have an inherent jitter of 125 ms. The processor load due to the driver is 0.6 percent on the P4.
    
		
    However, be acutely aware that the accuracy with Solaris 2.8 and beyond has been seriously degraded to the order of several milliseconds. The Sun kernel driver has a sawtooth modulation with amplitude over 5 ms P-P and period 5.5 s. This distortion is especially prevalent with Sun Blade 1000 and possibly other systems.
    
		
    The driver performs a number of error checks to protect against overdriven or underdriven input signal levels, incorrect signal format or improper hardware configuration. The specific checks are detailed later in this page. Note that additional checks are done elsewhere in the reference clock interface routines.
    
		
    This driver incorporates several features in common with other audio drivers such as described in the Radio CHU Audio Demodulator/Decoder and the Radio WWV/H Audio Demodulator/Decoder pages. They include automatic gain control (AGC), selectable audio codec port and signal monitoring capabilities. For a discussion of these common features, as well as a guide to hookup, debugging and monitoring, see the Reference Clock Audio Drivers page.
    
		
    Technical Overview
    
		
    The IRIG signal format uses an amplitude-modulated carrier with pulse-width modulated data bits. For IRIG-B, the carrier frequency is 1000 Hz and bit rate 100 b/s; for IRIG-E, the carrier frequenchy is 100 Hz and bit rate 10 b/s. While IRIG-B provides the best accuracy, generally within a few tens of microseconds relative to IRIG time, it can also generate a significant processor load with older workstations. Generally, the accuracy with IRIG-E is about ten times worse than IRIG-B, but the processor load is somewhat less. Technical details about the IRIG formats can be found in IRIG Standard 200-98.
    
		
    The driver processes 8000-Hz m-law companded samples using separate signal filters for IRIG-B and IRIG-E, a comb filter, envelope detector and automatic threshold corrector. An infinite impulse response (IIR) 1000-Hz bandpass filter is used for IRIG-B and an IIR 130-Hz lowpass filter for IRIG-E. These are intended for use with noisy signals, such as might be received over a telephone line or radio circuit, or when interfering signals may be present in the audio passband. The driver determines which IRIG format is in use by sampling the amplitude of each filter output and selecting the one with maximum signal.
    
		
    Cycle crossings relative to the corrected slice level determine the width of each pulse and its value - zero, one or position identifier (PI). The data encode ten characters (20 BCD digits) which determine the second, minute, hour and day of the year and with some IRIG generators the year and synchronization condition. The comb filter exponentially averages the corresponding samples of successive baud intervals in order to reliably identify the reference carrier cycle.
    
		
    A type-II phase-lock loop (PLL) performs additional integration and interpolation to accurately determine the zero crossing of that cycle, which determines the reference timestamp. A pulse-width discriminator demodulates the data pulses, which are then encoded as the BCD digits of the timecode. The timecode and reference timestamp are updated once each second with IRIG-B (ten seconds with IRIG-E) and local clock offset samples saved for later processing. At poll intervals of 64 s, the saved samples are processed by a median filter and used to update the system clock.
    
		
    Monitor Data
    
		The timecode format used for debugging and data recording includes data helpful in diagnosing problems with the IRIG signal and codec connections. The driver produces one line for each timecode in the following format:
		
    00 00 98 23 19:26:52 2782 143 0.694 10 0.3 66.5 3094572411.00027
    
		
    If clockstats is enabled, the most recent line is written to the clockstats file every 64 s. If verbose recording is enabled (fudge flag 4) each line is written as generated.
    
		
    The first field containes the error flags in hex, where the hex bits are interpreted as below. This is followed by the year of century, day of year and time of day. Note that the time of day is for the previous minute, not the current time. The status indicator and year are not produced by some IRIG devices and appear as zeros. Following these fields are the carrier amplitude (0-3000), codec gain (0-255), modulation index (0-1), time constant (4-10), carrier phase error (0±0.5) and carrier frequency error (PPM). The last field is the on-time timestamp in NTP format.
    
		
    The error flags are defined as follows in hex:
    
		
    
			
    x01
			
    Low signal. The carrier amplitude is less than 100 units. This is usually the result of no signal or wrong input port.
			
    x02
			
    Frequency error. The codec frequency error is greater than 250 PPM. This may be due to wrong signal format or (rarely) defective codec.
			
    x04
			
    Modulation error. The IRIG modulation index is less than 0.5. This is usually the result of an overdriven codec, wrong signal format or wrong input port.
			
    x08
			
    Frame synch error. The decoder frame does not match the IRIG frame. This is usually the result of an overdriven codec, wrong signal format or noisy IRIG signal. It may also be the result of an IRIG signature check which indicates a failure of the IRIG signal synchronization source.
			
    x10
			
    Data bit error. The data bit length is out of tolerance. This is usually the result of an overdriven codec, wrong signal format or noisy IRIG signal.
			
    x20
			
    Seconds numbering discrepancy. The decoder second does not match the IRIG second. This is usually the result of an overdriven codec, wrong signal format or noisy IRIG signal.
			
    x40
			
    Codec error (overrun). The machine is not fast enough to keep up with the codec.
			
    x80
			
    Device status error (Spectracom).

    Hewlett Packard 58503A GPS Receiver and HP Z3801A
    
        
    
        
    Synopsis
    
        
    Address: 127.127.26.u
    
            Reference ID: GPS
    
            Driver ID: GPS_HP
    
            Serial Port: /dev/hpgpsu; 9600 baud, 8-bits, no parity, 19200 baud 7-bits, odd parity for the HP Z3801A
    
        
    Description
    
        
    This driver supports the HP 58503A Time and Frequency Reference Receiver and HP Z3801A GPS Receiver. They use HP SmartClock (TM) to implement an Enhanced GPS receiver. The receiver accuracy when locked to GPS in normal operation is better than 1 usec. The accuracy when operating in holdover is typically better than 10 us per day. It receiver should be operated with factory default settings. Initial driver operation: expects the receiver to be already locked to GPS, configured and able to output timecode format 2 messages.
    
        
    The driver uses the poll sequence :PTIME:TCODE? to get a response from the receiver. The receiver responds with a timecode string of ASCII printing characters, followed by a <cr><lf>, followed by a prompt string issued by the receiver, in the following format:
    
        
    T#yyyymmddhhmmssMFLRVcc<cr><lf>scpi >
    
        The driver processes the response at the <cr> and <lf>, so what the driver sees is the prompt from the previous poll, followed by this timecode. The prompt from the current poll is (usually) left unread until the next poll. So (except on the very first poll) the driver sees this:
        
    scpi >T#yyyymmddhhmmssMFLRVcc<cr><lf>
    
        
    The T is the on-time character, at 980 msec. before the next 1PPS edge. The # is the timecode format type. We look for format 2. Without any of the CLK or PPS stuff, then, the receiver buffer timestamp at the <cr> is 24 characters later, which is about 25 msec. at 9600 bps, so the first approximation for fudge time1 is nominally -0.955 seconds. This number probably needs adjusting for each machine / OS type, so far: -0.955000 on an HP 9000 Model 712/80 HP-UX 9.05 -0.953175 on an HP 9000 Model 370 HP-UX 9.10
    
This driver will probably work with the 58503B and 59551A if they are setup appropriately.
    
To use an HP Z3801A, specify mode 1 on the server config line to setup the right line paramters.
    
The timekeeping portion of HP's business has been sold to Symmetricom.

				Reference ID: WWVB
    
				Driver ID: ULINK
    
				Serial Port: /dev/wwvbu; 9600 bps, 8-bits, no parity
    
				Features: (none)
    
		
    Description
    
		
    This driver supports the Ultralink Model 325 (replacement for Model 320) RS-232 powered WWVB receiver. PDF specs available on http://www.ulio.com/. This driver also supports the Model 320, 330,331,332 decoders in both polled or continous time code mode.Leap second and quality are supported. Most of this code is originally from refclock_wwvb.c with thanks. Any mistakes are mine. Any improvements are welcome.

    Note that Model 325 reports a very similar output like Model 33X series. The driver for this clock is similar to Model 33X behavior. On a unmodified new ULM325 clock, the polling flag (flag1 =1) needs to be set.

		ONCORE - SHMEM
		
	

	
		
    Motorola ONCORE - The Shared Memory Interface
    
		
    
		
    Introduction
    
		
    In NMEA mode, the Oncore GPS receiver provides the user with the same information as other GPS receivers. In BINARY mode, it can provide a lot of additional information.
    
		
    In particular, you can ask for satellite positions, satellite health, signal levels, the ephemeris and the almanac, and you can set many operational parameters. In the case of the VP, you can get the pseudorange corrections necessary to act as a DGPS base station, and you can see the raw satellite data messages themselves.
    
		
    When using the Oncore GPS receiver with NTP, this additional information is usually not available since the receiver is only talking to the oncore driver in NTPD. To make this information available for use in other programs, (say graphic displays of satellites positions, plots of SA, etc.), a shared memory interface (SHMEM) has been added to the refclock_oncore driver on those operating systems that support shared memory.
    
		
    To make use of this information you will need an Oncore Reference Manual for the Oncore GPS receiver that you have. The Manual for the VP only exists as a paper document, the UT+/GT+/M12 manuals are available as a pdf documents at Synergy .
    
		
    This interface was written by Poul-Henning Kamp (phk@FreeBSD.org), and modified by Reg Clemens (reg@dwf.com). The interface is known to work in FreeBSD, Linux, and Solaris.
    
		
    Activating the Interface
    
		
    Although the Shared Memory Interface will be compiled into the Oncore driver on those systems where Shared Memory is supported, to activate this interface you must include a STATUS or SHMEM line in the /etc/ntp.oncore data file that looks like
    
		
            STATUS < file_name >
    
			
        or
    
			
        SHMEM < file_name >

    
		Thus a line like
		
            SHMEM /var/adm/ntpstats/ONCORE

    
		
    would be acceptable. This file name will be used to access the Shared Memory.
    
		
    In addition, one the two keywords Posn2D and Posn3D can be added to see @@Ea records containing the 2D or 3D position of the station (see below). Thus to activate the interface, and see 3D positions, something like
    
		
            SHMEM /var/adm/ntpstats/ONCORE
        Posn3D

    
		
    would be required.
    
		
    Storage of Messages in Shared Memory
    
		
    With the shared memory interface, the oncore driver (refclock_oncore) allocates space for all of the messages that it is configured to receive, and then puts each message in the appropriate slot in shared memory as it arrives from the receiver. Since there is no easy way for a client program to know when the shared memory has been updated, a sequence number is associated with each message, and is incremented when a new message arrives. With the sequence number it is easy to check through the shared memory segment for messages that have changed.
    
		
    The Oncore binary messages are kept in their full length, as described in the Reference manual, that is everything from the @@ prefix thru the <checksum><CR><LF>.
    
		
    The data starts at location ONE of SHMEM (NOT location ZERO).
    
		
    The messages are stacked in a series of variable length structures, that look like
    
		
            struct message {
                u_int   length;
                u_char  sequence;
                u_char  message[length];
        }

    
		
    if something like that were legal. That is, there are two bytes (caution, these may NOT be aligned with word boundaries, so the field needs to be treated as a pair of u_char), that contains the length of the next message. This is followed by a u_char sequence number, that is incremented whenever a new message of this type is received. This is followed by 'length' characters of the actual message.
    
		
    The next structure starts immediately following the last char of the previous message (no alignment). Thus, each structure starts a distance of 'length+3' from the previous structure.
    
		
    Following the last structure, is a u_int containing a zero length to indicate the end of the data.
    
		
    The messages are recognized by reading the headers in the data itself, viz @@Ea or whatever.
    
		
    There are two special cases.
    
		
    (1) The almanac takes a total of 34 submessages all starting with @@Cb.
    
			35 slots are allocated in shared memory. Each @@Cb message is initially placed in the first of these locations, and then later it is moved to the appropriate location for that submessage. The submessages can be distinguished by the first two characters following the @@Cb header, and new data is received only when the almanac changes.
    
		
    (2) The @@Ea message contains the calculated location of the antenna, and is received once per second. However, when in timekeeping mode, the receiver is normally put in 0D mode, with the position fixed, to get better accuracy. In 0D mode no position is calculated.
    
		
    When the SHMEM option is active, and if one of Posn2D or Posn3D is specified, one @@Ea record is hijacked each 15s, and the receiver is put back in 2D/3D mode so the the current location can be determined (for position determination, or for tracking SA). The timekeeping code is careful NOT to use the time associated with this (less accurate) 2D/3D tick in its timekeeping functions.
    
		
    Following the initial @@Ea message are 3 additional slots for a total of four. As with the almanac, the first gets filled each time a new record becomes available, later in the code, the message is distributed to the appropriate slot. The additional slots are for messages containing 0D, 2D and 3D positions. These messages can be distinguished by different bit patterns in the last data byte of the record.
    
		
    Opening the Shared Memory File
    
		
    The shared memory segment is accessed through a file name given on a SHMEM card in the /etc/ntp.oncore input file. The following code could be used to open the Shared Memory Segment:
    
		
            char *Buf, *file;
        int size, fd;
        struct stat statbuf;

        file = "/var/adm/ntpstats/ONCORE";  /* the file name on my ACCESS card */
        if ((fd=open(file, O_RDONLY)) < 0) {
                fprintf(stderr, "Cant open %s\n", file);
                exit(1);
        }

        if (stat(file, &statbuf) < 0) {
                fprintf(stderr, "Cant stat %s\n", file);
                exit(1);
        }

        size = statbuf.st_size;
        if ((Buf=mmap(0, size, PROT_READ, MAP_SHARED, fd, (off_t) 0)) < 0) {
                fprintf(stderr, "MMAP failed\n");
                exit(1);
        }

    
		
    Accessing the data
    
		
    The following code shows how to get to the individual records.
    
		
            void    oncore_msg_Ea(), oncore_msg_As(), oncore_msg_Bb();

        struct Msg {
            char         c[5];
            unsigned int seq;
            void         (*go_to)(uchar *);
        };

        struct Msg Hdr[] = { {"@@Bb", 0, &oncore_msg_Bb},
                             {"@@Ea", 0, &oncore_msg_Ea},
                             {"@@As", 0, &oncore_msg_As}};

        void
        read_data()
        {
            int     i, j, k, n, iseq, jseq;
            uchar   *cp, *cp1;


            for(cp=Buf+1; (n = 256*(*cp) + *(cp+1)) != 0;  cp+=(n+3)) {
                for (k=0; k < sizeof(Hdr)/sizeof(Hdr[0]);  k++) {
                    if (!strncmp(cp+3, Hdr[k].c, 4)) {      /* am I interested? */
                        iseq = *(cp+2);
                        jseq = Hdr[k].seq;
                        Hdr[k].seq = iseq;
                        if (iseq > jseq) {              /* has it changed? */
                            /* verify checksum */
                            j = 0;
                            cp1 = cp+3;             /* points to start of oncore response */
                            for (i=2; i < n-3; i++)
                                j ^= cp1[i];
                            if (j == cp1[n-3]) {    /* good checksum */
                                    Hdr[k].go_to(cp1);
                            } else {
                                fprintf(stderr, "Bad Checksum for %s\n", Hdr[k].c);
                                break;
                            }
                        }
                    }
                }
                if (!strncmp(cp+3, "@@Ea", 4))
                    cp += 3*(n+3);
                if (!strncmp(cp+3, "@@Cb", 4))
                    cp += 34*(n+3);
            }
        }

        oncore_msg_Bb(uchar *buf)
        {
                /* process Bb messages */
        }

        oncore_msg_Ea(uchar *buf)
        {
                /* process Ea messages */
        }

        oncore_msg_As(uchar *buf)
        {
                /* process As messages */
        }

    
		
    The structure Hdr contains the Identifying string for each of the messages that we want to examine, and the name of a program to call when a new message of that type is arrives. The loop can be run every few seconds to check for new data.
    
		
    Examples
    
		
    There are two complete examples available. The first plots satellite positions and the station position as affected by SA, and keeps track of the mean station position, so you can run it for periods of days to get a better station position. The second shows the effective horizon by watching satellite tracks. The examples will be found in the GNU-zipped tar file ftp://ftp.udel.edu/pub/ntp/software/OncorePlot.tar.gz.
    
		
    Try the new interface, enjoy.

		Arbiter 1088A/B GPS Receiver
		
	

	
		
    Arbiter 1088A/B GPS Receiver
    
		
    
		
    Synopsis
    
		
    Address: 127.127.11.u
    
			Reference ID: GPS
    
			Driver ID: GPS_ARBITER
    
			Serial Port: /dev/gpsu; 9600 baud, 8-bits, no parity
    
			Features: tty_clk
    
		
    Description
    
		
    This driver supports the Arbiter 1088A/B Satellite Controlled Clock. The claimed accuracy of this clock is 100 ns relative to the PPS output when receiving four or more satellites.
    
		
    The receiver should be configured before starting the NTP daemon, in order to establish reliable position and operating conditions. It does not initiate surveying or hold mode. For use with NTP, the daylight savings time feature should be disables (D0 command) and the broadcast mode set to operate in UTC (BU command).
    
		
    The timecode format supported by this driver is selected by the poll sequence B5, which initiates a line in the following format to be repeated once per second until turned off by the B0 command.
    
		
    Format B5 (24 ASCII printing characters):
    
		
    <cr><lf>i yy ddd hh:mm:ss.000bbb

on-time = <cr>
i = synchronization flag (' ' = locked, '?' = unlocked)
yy = year of century
ddd = day of year
hh:mm:ss = hours, minutes, seconds
.000 = fraction of second (not used)
bbb = tailing spaces for fill
    
		
    The alarm condition is indicated by a '?' at i, which indicates the receiver is not synchronized. In normal operation, a line consisting of the timecode followed by the time quality character (TQ) followed by the receiver status string (SR) is written to the clockstats file.
    
		
    The time quality character is encoded in IEEE P1344 standard:
    
		
    Format TQ (IEEE P1344 estimated worst-case time quality)
    
		
    0       clock locked, maximum accuracy

    When enabled by the flag4 fudge flag, an additional line containing the latitude, longitude, elevation and optional deviation data is written to the clockstats file. The deviation data operates with an external pulse-per-second (PPS) input, such as a cesium oscillator or another radio clock. The PPS input should be connected to the B event channel and the radio initialized for deviation data on that channel. The deviation data consists of the mean offset and standard deviation of the external PPS signal relative the GPS signal, both in microseconds over the last 16 seconds.

    Radio WWV/H Audio Demodulator/Decoder
    
		
    
		
    Synopsis
    
		Address: 127.127.36.u
    
			Reference ID: WVf or WHf
    
		Driver ID: WWV_AUDIO
    
		Autotune Port: /dev/icom; 1200/9600 baud, 8-bits, no parity
    
		Audio Device: /dev/audio and /dev/audioctl
		
    Description
    This driver synchronizes the computer time using shortwave radio transmissions from NIST time/frequency stations WWV in Ft. Collins, CO, and WWVH in Kauai, HI. Transmissions are made continuously on 2.5, 5, 10 and 15 MHz from both stations and on 20 MHz from WWV. An ordinary shortwave receiver can be tuned manually to one of these frequencies or, in the case of ICOM receivers, the receiver can be tuned automatically by the driver as propagation conditions change throughout the day and season. The radio is connected via an optional attenuator and cable to either the microphone or line-in port of a workstation or PC.
		
    The driver requires an audio codec or sound card with sampling rate 8 kHz and m-law companding to demodulate the data. This is the same standard as used by the telephone industry and is supported by most hardware and operating systems, including Solaris, FreeBSD and Linux, among others. In this implementation only one audio driver and codec can be supported on a single machine. In order to assure reliable signal capture, the codec frequency error must be less than 187 PPM (.0187 percent). If necessary, the tinker codec configuration command can be used to bracket the codec frequency to this range.
    
		
    In general and without calibration, the driver is accurate within 1 ms relative to the broadcast time when tracking a station. However, variations up to 0.3 ms can be expected due to diurnal variations in ionospheric layer height and ray geometry. In Newark DE, 2479 km from the transmitter, the predicted two-hop propagation delay varies from 9.3 ms in sunlight to 9.0 ms in moonlight. When not tracking the station the accuracy depends on the computer clock oscillator stability, ordinarily better than 0.5 PPM.
    
		
    After calibration relative to the PPS signal from a GPS receiver, the mean offset with a 2.4-GHz P4 running FreeBSD 6.1 is generally within 0.1 ms short-term with 0.4 ms jitter. The long-term mean offset varies up to 0.3 ms due to propagation path geometry variations. The processor load due to the driver is 0.4 percent on the P4.
    
		
    The driver performs a number of error checks to protect against overdriven or underdriven input signal levels, incorrect signal format or improper hardware configuration. The specific checks are detailed later in this page. Note that additional checks are done elsewhere in the reference clock interface routines.
    
		
    This driver incorporates several features in common with other audio drivers such as described in the Radio CHU Audio Demodulator/Decoder and the IRIG Audio Decoder pages. They include automatic gain control (AGC), selectable audio codec port and signal monitoring capabilities. For a discussion of these common features, as well as a guide to hookup, debugging and monitoring, see the Reference Clock Audio Drivers page.
    
		
    Technical Overview
    
		
    The driver processes 8-kHz m-law companded codec samples using maximum-likelihood techniques which exploit the considerable degree of redundancy available in the broadcast signal. The WWV signal format is described in NIST Special Publication 432 (Revised 1990) and also available on the WWV/H web site. It consists of three elements, a 5-ms, 1000-Hz pulse, which occurs at the beginning of each second, a 800-ms, 1000-Hz pulse, which occurs at the beginning of each minute, and a pulse-width modulated 100-Hz subcarrier for the data bits, one bit per second. The WWVH format is identical, except that the 1000-Hz pulses are sent at 1200 Hz. Each minute encodes nine BCD digits for the time of century plus seven bits for the daylight savings time (DST) indicator, leap warning indicator and DUT1 correction.
    
		
    The demodulation and decoding algorithms used by this driver are based on a machine language program developed for the TAPR DSP93 DSP unit, which uses the TI 320C25 DSP chip. The analysis, design and performance of the program for this unit is described in: Mills, D.L. A precision radio clock for WWV transmissions. Electrical Engineering Report 97-8-1, University of Delaware, August 1997, 25 pp. Available from www.eecis.udel.edu/~mills/reports.htm. For use in this driver, the original program was rebuilt in the C language and adapted to the NTP driver interface. The algorithms have been modified to improve performance, especially under weak signal conditions and to provide an automatic frequency and station selection feature.
    
		
    As in the original program, the clock discipline is modelled as a Markov process, with probabilistic state transitions corresponding to a conventional clock and the probabilities of received decimal digits. The result is a performance level with very high accuracy and reliability, even under conditions when the minute beep of the signal, normally its most prominent feature, can barely be detected by ear using a communications receiver.
    
		
    Baseband Signal Processing
    
		
    The 1000/1200-Hz pulses and 100-Hz subcarrier are first separated using a 600-Hz bandpass filter centered on 1100 Hz and a 150-Hz lowpass filter. The minute pulse is extracted using an 800-ms synchronous matched filter and pulse grooming logic which discriminates between WWV and WWVH signals and noise. The second pulse is extracted using a 5-ms FIR matched filter for each station and a single 8000-stage comb filter.
    
		
    The phase of the 100-Hz subcarrier relative to the second pulse is fixed at the transmitter; however, the audio stage in many radios affects the phase response at 100 Hz in unpredictable ways. The driver adjusts for each radio using two 170-ms synchronous matched filters. The I (in-phase) filter is used to demodulate the subcarrier envelope, while the Q (quadrature-phase) filter is used in a type-1 phase-lock loop (PLL) to discipline the demodulator phase.
    
		
    A bipolar data signal is determined from the matched filter subcarrier envelope using a pulse-width discriminator. The discriminator samples the I channel at 15 ms (n),  200 ms (s0) and 500 ms (s1), and the envelope (RMS I and Q channels) at 200 ms (e1) and the end of the second (e0). The bipolar data signal is expressed 2s1 - s0 - n, where positive values correspond to data 1 and negative values correspond to data 0. Note that, since the signals s0 and s1 include the noise n, the noise component cancels out. The data bit SNR is calculated as 20 log10(e1 / e0). If the driver has not synchronized to the minute pulse, or if the data bit amplitude e1 or SNR are below thresholds, the bit is considered invalid and the bipolar signal is forced to zero.
    
		
    The bipolar signal is exponentially averaged in a set of 60 accumulators, one for each second, to determine the semi-static miscellaneous bits, such as DST indicator, leap second warning and DUT1 correction. In this design a data average value larger than a positive threshold is interpreted as +1 (hit) and a value smaller than a negative threshold as a -1 (miss). Values between the two thresholds, which can occur due to signal fades, are interpreted as an erasure and result in no change of indication.
    
		
    Maximum-Likelihood Decoder
    
		
    The BCD digit in each digit position of the timecode is represented as four data bits. The bits are correlated with the bits corresponding to each of the valid decimal digits in this position. If any of the four bits are invalid, the correlated value for all digits in this position is assumed zero. In either case, the values for all digits are exponentially averaged in a likelihood vector associated with this position. The digit associated with the maximum over all averaged values then becomes the maximum-likelihood candidate for this position and the ratio of the maximum over the next lower value represents the digit SNR.
    
		
    The decoding matrix contains nine row vectors, one for each digit position. Each row vector includes the maximum-likelihood digit, likelihood vector and other related data. The maximum-likelihood digit for each of the nine digit positions becomes the maximum-likelihood time of the century. A built-in transition function implements a conventional clock with decimal digits that count the minutes, hours, days and years, as corrected for leap seconds and leap years. The counting operation also rotates the likelihood vector corresponding to each digit as it advances. Thus, once the clock is set, each clock digit should correspond to the maximum-likelihood digit as transmitted.
    
		
    Each row of the decoding matrix also includes a compare counter and the most recently determined maximum-likelihood digit. If a digit likelihood exceeds the decision level and compares with previous digits for a number of successive minutes in any row, the maximum-likelihood digit replaces the clock digit in that row. When this condition is true for all rows and the second epoch has been reliably determined, the clock is set (or verified if it has already been set) and delivers correct time to the integral second. The fraction within the second is derived from the logical master clock, which runs at 8000 Hz and drives all system timing functions.
    
		
    Master Clock Discipline
    
		
    The logical master clock is derived from the audio codec clock. Its frequency is disciplined by a frequency-lock loop (FLL) which operates independently of the data recovery functions. The maximum value of the 5-ms pulse after the comb filter represents the on-time epoch of the second. At averaging intervals determined by the measured jitter, the frequency error is calculated as the difference between the epoches over the interval divided by the interval itself. The sample clock frequency is then corrected by this amount divided by a time constant of 8.
    
		
    When first started, the frequency averaging interval is 8 seconds, in order to compensate for intrinsic codec clock frequency offsets up to 125 PPM. Under most conditions, the averaging interval doubles in stages from the initial value to 1024 s, which results in an ultimate frequency resolution of 0.125 PPM, or about 11 ms/day.
    
		
    The data demodulation functions operate using the subcarrier clock, which is independent of the epoch. However, the data decoding functions are driven by the epoch. The decoder is phase-locked to the epoch in such a way that, when the clock state machine has reliably decoded the broadcast time to the second, the epoch timestamp of that second becomes a candidate to set the system clock.
    
		
    The comb filter can have a long memory and is vulnerable to noise and stale data, especially when coming up after a long fade. Therefore, a candidate is considered valid only if the 5-ms signal amplitude and SNR are above thresholds. In addition, the system clock is not set until after one complete averaging interval has passed with valid candidates.
    
		
    Station Identification
    
		
    It is important that the logical clock frequency is stable and accurately determined, since in many applications the shortwave radio will be tuned to a fixed frequency where WWV or WWVH signals are not available throughout the day. In addition, in some parts of the US, especially on the west coast, signals from either or both WWV and WWVH may be available at different times or even at the same time. Since the propagation times from either station are almost always different, each station must be reliably identified before attempting to set the clock.
    
		
    Reliable station identification requires accurate discrimination between very weak signals in noise and noise alone. The driver very aggressively soaks up every scrap of signal information, but has to be careful to avoid making pseudo-sense of noise alone. The signal quality metric depends on the minute pulse amplitude and SNR measured in second 0 of the minute, together with the data subcarrier amplitude and SNR measured in second 1. If all four values are above defined thresholds a hit is declared, otherwise a miss. In principle, the data pulse in second 58 is usable, but the AGC in most radios is not fast enough for a reliable measurement.
    
		
    The number of hits declared in the last 6 minutes for each station represents the high order bits of the metric, while the current minute pulse amplitude represents the low order bits. Only if the metric is above a defined threshold is the station signal considered acceptable. The metric is also used by the autotune function described below and reported in the timecode string.
    
		
    Performance
    
		
    It is the intent of the design that the accuracy and stability of the indicated time be limited only by the characteristics of the ionospheric propagation medium. Conventional wisdom is that manual synchronization via oscilloscope and HF medium is good only to a millisecond under the best propagation conditions. The performance of the NTP daemon disciplined by this driver is clearly better than this, even under marginal conditions.
    
		
    The figure below shows the measured offsets over a typical day near the bottom of the sunspot cycle ending in October, 2006. Variations up to ±0.4 ms can be expected due to changing ionospheric layer height and ray geometry over the day and night.
    
		
    
			gif
    
		
    The figure was constructed using a 2.4-GHz P4 running FreeBSD 6.1. For these measurements the computer clock was disciplined within a few microseconds of UTC using a PPS signal and GPS receiver and the measured offsets determined from the filegen peerstats data.
    
		
    The predicted propagation delay from the WWV transmitter at Boulder, CO, to the receiver at Newark, DE, varies over 9.0-9.3 ms. In addition, the receiver contributes 4.7 ms and the 600-Hz bandpass filter 0.9 ms. With these values, the mean error is less than 0.1 ms and varies ±0.3 ms over the day as the result of changing ionospheric height and ray geometry.
    
		
    Program Operation
    
		The driver begins operation immediately upon startup. It first searches for one or both of the stations WWV and WWVH and attempts to acquire minute synch. This may take some fits and starts, as the driver expects to see several consecutive minutes with good signals and low jitter. If the autotune function is active, the driver will rotate over all five frequencies and both WWV and WWVH stations until finding a station and frequency with acceptable metric.
		
    While this is going on the the driver acquires second synch, which can take up to several minutes, depending on signal quality. When minute synch has been acquired, the driver accumulates likelihood values for the unit (seconds) digit of the nine timecode digits, plus the seven miscellaneous bits included in the WWV/H transmission format. When a good unit digit has been found, the driver accumulated likelihood values for the remaining eight digits of the timecode. When three repetitions of all nine digits have decoded correctly, which normally takes 15 minutes with good signals, and up to 40 minutes when buried in noise, and the second synch has been acquired, the clock is set (or verified) and is selectable to discipline the system clock.
    
		
    Once the clock is set, it continues to provide correct timecodes as long as the signal metric is above threshold, as described in the previous section. As long as the clock is correctly set or verified, the system clock offsets are provided once each minute to the reference clock interface, where they are processed using the same algorithms as with other reference clocks and remote servers.
    
		
    It may happen as the hours progress around the clock that WWV and WWVH signals may appear alone, together or not at all. When the driver has mitigated which station and frequency is best, it sets the reference identifier to the string WVf for WWV and WHf for WWVH, where f is the frequency in megahertz. If the propagation delays have been properly set with the fudge time1 (WWV) and fudge time2 (WWVH) commands in the configuration file, handover from one station to the other is seamless.
    
		
    Operation continues as long as the signal metric from at least one station on at least one frequency is acceptable. A consequence of this design is that, once the clock is set, the time and frequency are disciplined only by the second synch pulse and the clock digits themselves are driven by the clock state machine. If for some reason the state machine drifts to the wrong second, it would never resynchronize. To protect against this most unlikely situation, if after two days with no signals, the clock is considered unset and resumes the synchronization procedure from the beginning.
    
		
    Once the system clock been set correctly it will continue to read correctly even during the holdover interval, but with increasing dispersion. Assuming the system clock frequency can be disciplined within 1 PPM, it can coast without signals for several days without exceeding the NTP step threshold of 128 ms. During such periods the root distance increases at 15 ms per second, which makes the driver appear less likely for selection as time goes on. Eventually, when the distance due all causes exceeds 1 s, it is no longer suitable for synchronization. Ordinarily, this  happens after about 18 hours with no signals. The tinker maxdist configuration command can be used to change this value.
    
		
    Autotune
    
		
    The driver includes provisions to automatically tune the radio in response to changing radio propagation conditions throughout the day and night. The radio interface is compatible with the ICOM CI-V standard, which is a bidirectional serial bus operating at TTL levels. The bus can be connected to a standard serial port using a level converter such as the CT-17. Further details are on the Reference Clock Audio Drivers page.
    
		
    If specified, the driver will attempt to open the device /dev/icom and, if successful will activate the autotune function and tune the radio to each operating frequency in turn while attempting to acquire minute synch from either WWV or WWVH. However, the driver is liberal in what it assumes of the configuration. If the /dev/icom link is not present or the open fails or the CI-V bus is inoperative, the driver quietly gives up with no harm done.
    
		
    Once acquiring minute synch, the driver operates as described above to set the clock. However, during seconds 59, 0 and 1 of each minute it tunes the radio to one of the five broadcast frequencies to measure the signal metric as described above. Each of the five frequencies are probed in a five-minute rotation to build a database of current propagation conditions for all signals that can be heard at the time. At the end of each probe a mitigation procedure scans the database and retunes the radio to the best frequency and station found. For this to work well, the radio should be set for a fast AGC recovery time. This is most important while tracking a strong signal, which is normally the case, and then probing another frequency, which may have much weaker signals.
    
		
    The mitigation procedure selects the frequency and station with the highest valid metric, ties going first to the highest frequency and then to WWV in order. A station is considered valid only if the metric is above a specified threshold; if no station is above the metric, the rotating probes continue until a valid station is found.
    
		
    The behavior of the autotune function over a typical day is shown in the figure below.
    
		
    
			gif
    
		
    As expected, the lower frequencies prevail when the ray path is in moonlight (0100-1300 UTC) and the higher frequencies when the path is in sunlight (1300-0100 UTC). Note three periods in the figure show zero frequency when signals are below the minimum for all frequencies and stations.
    
		
    Debugging Aids
    
		
    The most convenient way to track the driver status is using the ntpq program and the clockvar command. This displays the last determined timecode and related status and error counters, even when the driver is not disciplining the system clock. If the debugging trace feature (-d on the ntpd command line) is enabled, the driver produces detailed status messages as it operates. If the fudge flag 4 is set, these messages are written to the clockstats file. All messages produced by this driver have the prefix wwv for convenient filtering with the Unix grep command.
    
		
    The autotune process produces diagnostic information along with the timecode. This is very useful for evaluating the performance of the algorithms, as well as radio propagation conditions in general. The message is produced once each minute for each frequency in turn after minute synch has been acquired.
    
		
    wwv5 status agc epoch secamp/secsnr datamp/datsnr wwv wwvh
    
		
    where the fields after the wwv5 identifier are: status contains status bits, agc audio gain, epoch second epoch, secamp/secsnr second pulse amplitude/SNR, and wwv and wwvh are two sets of fields, one each for WWV and WWVH. Each of the two fields has the format
    
		
    ident score metric minamp/minsnr
    
		
    where ident encodes the station (WV for WWV, WH for WWVH) and frequency (2, 5, 10, 15 or 20), score 32-bit shift register recording the hits (1) and misses (0) of the last 32 probes (hits and misses enter from the right), metric is described above, and minamp/minsnr is the minute pulse ampliture/SNR. An example is:
    
		
    wwv5 000d 111 5753 3967/20.1 3523/10.2 WV20 bdeff 100 8348/30.0 WH20 0000 1 22/-12.4
    
		
    There are several other messages that can occur; these are documented in the source listing.
    
		
    Monitor Data
    
		
		
		When enabled by the filegen facility, every received timecode is written to the clockstats file in the following format:
		
    sq yyyy ddd hh:mm:ss l d du lset agc ident metric errs freq avg
    
			
    
			The fields beginning with yyyy and extending through du are decoded from the received data and are in fixed-length format. The remaining fields are in variable-length format. The fields are as follows:
		
    
			
    s
			
    The synch indicator is initially ? before the clock is set, but turns to space when all nine digits of the timecode are correctly set and the decoder is synchronized to the station within 125 ms.
			
    q
			
    The quality character is a four-bit hexadecimal code showing which alarms have been raised. Each bit is associated with a specific alarm condition according to the following:
				
    
					
    0x8
					
    synch alarm. The decoder is not synchronized to the station within 125 ms.
					
    0x4
					
    Digit error alarm. Less than nine decimal digits were found in the last minute.
    0x2
					
    Error alarm. More than 40 data bit errors were found in the last minute.
    0x1
					
    Compare alarm. A maximum-likelihood digit failed to agree with the current associated clock digit in the last minute.
    It is important to note that one or more of the above alarms does not necessarily indicate a clock error, but only that the decoder has detected a marginal condition.
    yyyy ddd hh:mm:ss
					
    The timecode format itself is self explanatory. Since the driver latches the on-time epoch directly from the second synch pulse, the seconds fraction is always zero. Although the transmitted timecode includes only the year of century, the Gregorian year is augmented by 2000.
					
    l
					
    The leap second warning is normally space, but changes to L if a leap second is to occur at the end of the month.
			
    d
			
    The DST state is S or D when standard time or daylight time is in effect, respectively. The state is I or O when daylight time is about to go into effect or out of effect, respectively.
			
    du
			
    The DUT sign and magnitude shows the current UT1 offset relative to the displayed UTC time, in deciseconds.
			
    lset
			
    Before the clock is set, the interval since last set is the number of minutes since the driver was started; after the clock is set, this is number of minutes since the decoder was last synchronized to the station within 125 ms.
			
    agc
			
    The audio gain shows the current codec gain setting in the range 0 to 255. Ordinarily, the receiver audio gain control should be set for a value midway in this range.
			
    ident
			
    The station identifier shows the station, WVf for WWV or WHf for WWVH, and frequency f being tracked. If neither station is heard on any frequency, the reference identifier shows NONE.
			
    metric
			
    The signal metric described above from 0 (no signal) to 100 (best).
			
    errs
			
    The bit error counter is useful to determine the quality of the data signal received in the most recent minute. It is normal to drop a couple of data bits even under good signal conditions and increasing numbers as conditions worsen. While the decoder performs moderately well even with half the bits are in error in any minute, usually by that point the metric drops below threshold and the decoder switches to a different frequency.
    freq
			
    The frequency offset is the current estimate of the codec frequency offset to within 0.1 PPM. This may wander a bit over the day due to local temperature fluctuations and propagation conditions.
			
    avg
			
    The averaging time is the interval between frequency updates in powers of two to a maximum of 1024 s. Attainment of the maximum indicates the driver is operating at the best possible resolution in time and frequency.
		
    
		
    An example timecode is:
    
		
    0 2000 006 22:36:00 S +3 1 115 WV20 86 5 66.4 1024
    
		
    Here the clock has been set and no alarms are raised. The year, day and time are displayed along with no leap warning, standard time and DUT +0.3 s. The clock was set on the last minute, the AGC is safely in the middle ot the range 0-255, and the receiver is tracking WWV on 20 MHz. Good receiving conditions prevail, as indicated by the metric 86 and 5 bit errors during the last minute. The current frequency is 66.4 PPM and the averaging interval is 1024 s, indicating the maximum precision available.
    
		
    Fudge Factors
    
		
    
			
    time1 time
			
    Specifies the propagation delay for WWV (40:40:49.0N 105:02:27.0W), in seconds and fraction, with default 0.0.
			
    time2 time
			
    Specifies the propagation delay for WWVH (21:59:26.0N 159:46:00.0W), in seconds and fraction, with default 0.0.
			
    stratum number
			
    Specifies the driver stratum, in decimal from 0 to 15, with default 0.
			
    refid string
			
    Ordinarily, this field specifies the driver reference identifier; however, the driver sets the reference identifier automatically as described above.
			
    flag1 0 | 1
			
    Not used by this driver.
			
    flag2 0 | 1
			
    Specifies the microphone port if set to zero or the line-in port if set to one. It does not seem useful to specify the compact disc player port.
			
    flag3 0 | 1
			
    Enables audio monitoring of the input signal. For this purpose, the speaker volume must be set before the driver is started.
			
    flag4 0 | 1
			
    Enable verbose clockstats recording if set.

    Synopsis
    
		
    Address: 127.127.10.u
    
			Reference ID: GPS
    
			Driver ID: GPS_AS2201
    
			Serial Port: /dev/gpsu; 9600 baud, 8-bits, no parity
    
			Features: tty_clk
    
		
    Description
    
		
    This driver supports the Austron 2200A/2201A GPS/LORAN Synchronized Clock and Timing Receiver connected via a serial port. It supports several special features of the clock, including the Input Buffer Module, Output Buffer Module, IRIG-B Interface Module and LORAN Assist Module. It requires the RS232 Buffered Serial Interface module for communication with the driver.
    
		
    For use with a single computer, the receiver can be connected directly to the receiver. For use with multiple computers, one of them is connected directly to the receiver and generates the polling messages. The other computers just listen to the receiver output directly or through a buffer amplifier. For computers that just listen, fudge flag2 must be set and the ppsclock streams module configured on each of them.
    
		
    This receiver is capable of a comprehensive and large volume of statistics and operational data. The specific data collection commands and attributes are embedded in the driver source code; however, the collection process can be enabled or disabled using the flag4 flag. If set, collection is enabled; if not, which is the default, it is disabled. A comprehensive suite of data reduction and summary scripts is in the ./scripts/stats directory
    
		of the ntp3 distribution.
		
    Monitor Data
    
		
    When enabled by the flag4 fudge flag, every received timecode is written as-is to the clockstats file.

    Description
    
        
    This driver supports several models models of Kinemetrics/TrueTime timing receivers, including 468-DC MK III GOES Synchronized Clock, GPS- DC MK III and GPS/TM-TMD GPS Synchronized Clock, XL-DC (a 151-602-210, reported by the driver as a GPS/TM-TMD), GPS-800 TCU (an 805-957 with the RS232 Talker/Listener module), OM-DC OMEGA Synchronized Clock, and very likely others in the same model family that use the same timecode formats.

                The carriage return start bit begins on 0 seconds and extends to 1 bit time.
        
    
        
    Notes on 468-DC and OMEGA receiver:
    
        
    Send the clock a R or C and once per second a timestamp will appear. Send a R to get the satellite position once (GOES only).
    
        
    Notes on the 468-DC receiver:
    
        
    Since the old east/west satellite locations are only historical, you can't set your clock propagation delay settings correctly and still use automatic mode. The manual says to use a compromise when setting the switches. This results in significant errors. The solution; use fudge time1 and time2 to incorporate corrections. If your clock is set for 50 and it should be 58 for using the west and 46 for using the east, use the line
    
        
    fudge 127.127.5.0 time1 +0.008 time2 -0.004
    
        
    This corrects the 4 milliseconds advance and 8 milliseconds retard needed. The software will ask the clock which satellite it sees.
    
        
    The PCL720 from PC Labs has an Intel 8253 look-alike, as well as a bunch of TTL input and output pins, all brought out to the back panel. If you wire a PPS signal (such as the TTL PPS coming out of a GOES or other Kinemetrics/Truetime clock) to the 8253's GATE0, and then also wire the 8253's OUT0 to the PCL720's INPUT3.BIT0, then we can read CTR0 to get the number of microseconds since the last PPS upward edge, mediated by reading OUT0 to find out if the counter has wrapped around (this happens if more than 65535us (65ms) elapses between the PPS event and our being called.)

    Description
    
		
    The refclock_hopf_serial driver supports hopf electronic receivers with serial Interface kompatibel 6021.
    
		
    
		
    Additional software and information about the software drivers is available from: http://www.ATLSoft.de/ntp.
    
		
    
		
    Latest NTP driver source, executables and documentation is maintained at: http://www.ATLSoft.de/ntp
    
		
    
		
    Operating System Compatibility
    
		
    The hopf clock driver has been tested on the following software and hardware platforms:

    O/S Serial Port Configuration
    
		The driver attempts to open the device /dev/hopfclockX where X is the NTP refclock unit number as defined by the LSB of the refclock address.  Valid refclock unit numbers are 0 - 3.
		
    The user is expected to provide a symbolic link to an available serial port device.  This is typically performed by a command such as:
    
		
    
			ln -s /dev/ttyS0 /dev/hopfclock0
    Windows NT does not support symbolic links to device files. 
    
		COMx: is used by the driver, based on the refclock unit number, where unit 1 corresponds to COM1: and unit 3 corresponds to COM3:
     
		
    
		
    Fudge Factors
    
		
    
			
    time1 time
			
    Specifies the time offset calibration factor, in seconds and fraction, with default 0.0. Should be set to 20 milliseconds to correct serial line and operating system delays incurred in capturing time stamps from the synchronous packets.
			
    refid string
			
    Specifies the driver reference identifier, GPS or DCF.

    Undisciplined Local Clock
    
		
    
		
    Synopsis
    
		
    Address: 127.127.1.u
    
			Reference ID: LCL
    
			Driver ID: LOCAL
    
		
    Description
    
		
    Not: This driver is not recommended for new installations. A much more flexible replacement is available in the form of orphan mode described on the Association Management page.
    
		
    This driver is intended for use in an isolated network where no external source of synchronization such as a radio clock or modem is available. It allows a designated time server to act as a primary server to provide synchronization to other clients on the network. Pick a machine that has a good clock oscillator (Digital machines are good, Sun machines are not) and configure it with this driver. Set the clock using the best means available, like eyeball-and-wristwatch. Then, point all the other machines at this one or use broadcast mode to distribute time.
    
		
    Another application for this driver is if a particular server clock is to be used as the clock of last resort when all other normal synchronization sources have gone away. This is especially useful if that server has an ovenized oscillator. For this you would usually, but not necessarily, configure this driver at a stratum greater than any other likely sources of time, such as the default 5 for this driver, to prevent this driver taking over when legitimate sources elsewher in the network are  available. To further protect the Internet infrastructure from accidental or malicious exposure to this driver, the driver is desabled if another source is available and operating.

    GPS Receiver
    
		The Palisade GPS receiver is an 8-channel smart antenna, housing the GPS receiver, antenna and interface in a single unit, and is designed for rooftop deployment in static timing applications.
		
    Palisade generates a PPS synchronized to UTC within +/- 100 ns.  The Palisade's external event input with 40 nanosecond resolution is utilized by the Palisade NTP driver for asynchronous precision time transfer.
    
		
    No user initialization of the receiver is required. This driver is compatible with the following versions of Palisade:

				Note: When using Palisade 26664-00, you must set fudge flag2 to 1 in ntp.conf. See configuration.
			
    
			
    
				
    GPS Installation
    
				A location with unobstructed view of the horizon is recommended. Palisade is designed to be securely mounted atop standard 3/4 inch threaded pipe.
				
    The 12 conductor (dia. 10 mm)  power and I/O cable must be routed from the rooftop site to the NTP server and properly strain relieved.
    
				
    GPS Connection
    
				The Palisade is equipped with dual (A & B) RS-422 serial interfaces and a differential TTL PPS output. An RS-232 / RS-422 Interface Module is supplied with the Palisade NTP Synchronization Kit. Palisade port A must be connected to the NTP host server. Maximum antenna cable length is 500 meters. See the pinouts table for detailed connection Information.
				
    Palisade's port B provides a TSIP (Trimble Standard Interface Protocol) interface for diagnostics, configuration, and monitoring. Port B and the PPS output are not currently used by the Palisade NTP reference clock driver.
     
    
			
    
		
    
		
    O/S Serial Port Configuration
    
		The driver attempts to open the device /dev/palisadeu where u is the NTP refclock unit number as defined by the LSB of the refclock address.  Valid refclock unit numbers are 0 - 3.
		
    The user is expected to provide a symbolic link to an available serial port device.  This is typically performed by a command such as:
    
		
    
			ln -s /dev/ttyS0 /dev/palisade0
    
		Windows NT does not support symbolic links to device files. COMx: is used by the driver, based on the refclock unit number, where unit 1 corresponds to COM1: and unit 3 corresponds to COM3:
     
		
    NTP Configuration
    
		Palisade NTP configuration file "ntp.conf" with event polling:
    
		#------------------------------------------------------------------------------
    
		# The Primary reference
    
		server 127.127.29.0 # Trimble Palisade GPS Refclock Unit #0
    
		peer terrapin.csc.ncsu.edu # internet server
    
		# Drift file for expedient re-synchronization after downtime or reboot.
    
		driftfile /etc/ntp.drift
    
		#------------------------------------------------------------------------------
		
    Configuration without event polling:
    
			#------------------------------------------------------------------------------
    
			# The Primary reference
    
			server 127.127.29.0 # Trimble Palisade GPS (Stratum 1).
    
			# Set packet delay
    
			fudge 127.127.29.0 time1 0.020
    
			# and set flag2 to turn off event polling.
    
			fudge 127.127.29.0 flag2 1
    
			#------------------------------------------------------------------------------
     
    
		
		
    Thunderbolt NTP Configuration file

    Configuration without event polling:
    
		#------------------------------------------------------------------------------
    
		# The Primary reference
    
		server 127.127.29.0 mode 2 # Trimble Thunderbolt GPS (Stratum 1).
    
		# Set packet delay
    
		fudge 127.127.29.0 time1 0.020
    
		# and set flag2 to turn off event polling.
    
		fudge 127.127.29.0 flag2 1
    
		#------------------------------------------------------------------------------
     
    
		Currently the Thunderbolt mode doesn't support event polling, the reasons are explained on the "Notes on the Thunderbolt Receiver's Firmware" section at the end of this documentation.
		
    Time Transfer and Polling
    
		Time transfer to the NTP host is performed via the Palisade's comprehensive time packet output. The time packets are output once per second, and whenever an event timestamp is requested.
		
    The driver requests an event time stamp at the end of each polling interval, by pulsing the RTS (request to send) line on the serial port. The Palisade GPS responds with a time stamped event packet.
    
		
    Time stamps are reported by the Palisade with respect to UTC time. The GPS receiver must download UTC offset information from GPS satellites. After an initial UTC download, the receiver will always start with correct UTC offset information.
     
    
		
    Run NTP in Debugging Mode
    
		The following procedure is recommended for installing and testing a Palisade NTP driver:
		
      
			
    1. Perform initial checkout procedures. Place the GPS receiver outdoors; with clear view of the sky. Allow the receiver to obtain an UTC almanac.
			
    2. Verify presence of timing packets by observing the 1 Hz (PPS) led on the interface module. It should flash once per second.
			
    3. Connect Palisade's port A to the NTP host.
			
    4. Configure NTP and the serial I/O port on the host system.
			
    5. Initially use fudge flag2 in ntp.conf, to disable event polling (see configuration).
			
    6. Run NTP in debug mode (-d -d), to observe Palisade_receive events.
			
    7. The driver reports the tracking status of the receiver. Make sure it is tracking several satellites.
			
    8. Remove fudge flag2 and restart ntpd in debug mode to observe palisade_receive events.
			
    9. If event polling fails, verify the connections and that the host hardware supports RTS control.
		
    
		
    Event Logging
    
		System and Event log entries are generated by NTP to report significant system events. Administrators should monitor the system log to observe NTP error messages. Log entries generated by the Palisade NTP reference clock driver will be of the form:
		
    
			
    Nov 14 16:16:21 terrapin ntpd[1127]: Palisade #0: message
    
		
    
		
    Fudge Factors
    
		
    
			
    time1 time
			
    Specifies the time offset calibration factor, in seconds and fraction, with default 0.0. If event capture is not used, time1 should be set to 20 milliseconds to correct serial line and operating system delays incurred in capturing time stamps from the synchronous packets.
			
    stratum number
			
    Specifies the driver stratum, in decimal from 0 to 15, with default 0.
			
    refid string
			
    Specifies the driver reference identifier, GPS.
			
    flag2 0 | 1
			
    When set to 1, driver does not use hardware event capture. The synchronous packet output by the receiver at the beginning of each second is time stamped by the driver. If triggering the event pulse fails, the driver falls back to this mode automatically.
		
    
		
    Mode Parameter
    
		
    
			
    mode number
			
    The mode parameter to the server command specifies the specific hardware this driver is for. The default is 0 for a normal Trimble Palisade. The other options are 1 for an Endrun Praecis in Trimble emulation mode, and 2 for the Trimble Thunderbolt GPS Disciplined Clock Receiver.
		
    
		
    DEFINEs
    
		The following constants are defined in the driver source code. These defines may be modified to improve performance or adapt to new operating systems.

    Notes on the Thunderbolt Receiver's Firmware
    

		The support for Thunderbolt Receiver in the palisade driver doesn't support (for now) event-polling, the reason is that the Thunderbolt receiver the patch is written for doesn't support time-on-request, so you just have to sit there and wait for the time to arrive with the PPS. We tried to contact Trimble because there's presumably a firmware update that support it, but we didn't have much luck.
Here is a link explaining the situation:

    Description
    
        
    This driver supports the KSI/Odetics TPRO and TPRO-SAT IRIG-B Decoder, which is a module connected directly to the SBus of a Sun workstation. The module works with the IRIG-B signal generated by several radio clocks, including those made by Arbiter, Austron, Odetics, Spectracom and TrueTime, among others, although it is generally an add- on option. In the case of the TPRO-SAT, the module is an integral part of a GPS receiver, which serves as the primary timing source.
    
        
    Using the TPRO interface as a NTP reference clock provides precision time only to ntpd and its clients. With suitable kernel modifications, it is possible to use the TPRO as the CPU system clock, avoiding errors introduced by the CPU clock oscillator wander. See the A Kernel Model for Precision Timekeeping page for further details.

    Conrad parallel port radio clock
    
		
    
		
    Synopsis
    
		
    Address: 127.127.35.u
    
			Reference ID: PCF
    
			Driver ID: PCF
    
			Parallel Port: /dev/pcfclocks/u or /dev/pcfclocku
    
		
    Description
    
		
    This driver supports the parallel port radio clock sold by Conrad Electronic under order numbers 967602 and 642002. This clock is put between a parallel port and your printer. It receives the legal German time, which is either CET or CEST, from the DCF77 transmitter and uses it to set its internal quartz clock. The DCF77 transmitter is located near to Frankfurt/Main and covers a radius of more than 1500 kilometers.
    
		
    The pcfclock device driver is required in order to use this reference clock driver. Currently device drivers for Linux and FreeBSD are available.
    
		
    This driver uses C library functions to convert the received timecode to UTC and thus requires that the local timezone be CET or CEST. If your server is not located in Central Europe you have to set the environment variable TZ to CET before starting ntpd.
    
		
    Monitor Data
    
		
    Each timecode is written to the clockstats file in the format YYYY MM DD HH MI SS.

		Generic Reference Driver
		
	

	
		
    Generic Reference Driver
    
		
    
		
    Synopsis
    
		Address: 127.127.8.u
    
		Reference ID: PARSE
    
		Driver ID: GENERIC
    
		Serial Port: /dev/refclock-u; TTY mode according to clock type
    
                PPS device: /dev/refclockpps-u; alternate PPS device (if not available via the serial port)
		
    Description
    
		The PARSE driver supports 20 different clock types/configurations. PARSE is actually a multi-clock driver.
    
		
    
		
    The actual receiver status is mapped into various synchronization states generally used by receivers. The driver is configured to interpret the time codes of Meinberg DCF77 AM receivers, DCF77 FM receivers, Meinberg GPS16x/17x receivers, Trimble SV6 GPS, ELV DCF7000, Schmid, Wharton 400A and low cost receivers (see list below).
    
		
    The reference clock support in NTP contains the necessary configuration tables for those receivers. In addition to supporting several different clock types and up to 4 devices, the processing of a PPS signal is also provided as a configuration option. The PPS configuration option uses the receiver-generated time stamps for feeding the PPS loopfilter control for much finer clock synchronization.
    
		
    CAUTION: The PPS configuration option is different from the hardware PPS signal, which is also supported (see below), as it controls the way ntpd is synchronized to the reference clock, while the hardware PPS signal controls the way time offsets are determined.
    
		
    The use of the PPS option requires receivers with an accuracy of better than 1ms.
    
		
    Timecode variables listed by ntpq (8)
    
		
    The ntpq program can read and display several clock variables. These hold the following information:
    
		
    
			
    refclock_format
    
			
    A qualification of the decoded time code format.
    
			
    refclock_states
    
			
    The overall running time and the accumulated times for the clock event states.
    
			
    refclock_status
    
			
    Lists the currently active receiver flags. Additional feature flags for the receiver are optionally listed in parentheses.
    
			
    refclock_time
    
			
    The local time with the offset to UTC (format HHMM).
    
			
    timecode
    
			
    The actual time code.
    
		
    
		
    If PPS information is present, additional variables are available:
    
		
    
			
    refclock_ppsskew
    
			
    The difference between the RS-232-derived timestamp and the PPS timestamp.
    
			
    refclock_ppstime
    
			
    The PPS timestamp.
    
		
    
		
    Supported Devices
    
		
    Currently, nineteen clock types (devices /dev/refclock-0 - /dev/refclock-3) are supported by the PARSE driver.
    
			A note on the implementations:
    
		
      
			
    • These implementations were mainly done without actual access to the hardware, thus not all implementations provide full support. The development was done with the help of many kind souls who had the hardware and kindly lent me their time and patience during the development and debugging cycle. Thus for continued support and quality, direct access to the receivers is a big help. Nevertheless I am not prepared to buy these reference clocks - donations to (kardel <AT> ntp.org) are welcome as long as they work within Europe 8-).
				
      Verified implementations are:
      
				
        
					
      • RAWDCF variants
						
        These variants have been tested for correct decoding with my own homegrown receivers. Interfacing with specific commercial products may involve some fiddling with cables. In particular, commercial RAWDCF receivers have a seemingly unlimited number of ways to draw power from the RS-232 port and to encode the DCF77 datastream. You are mainly on your own here unless I have a sample of the receiver.
        
					
      • Meinberg clocks
						
        These implementations have been verified by the Meinberg people themselves and I have access to one of these clocks.

      This mode expects either the University of Erlangen time string format or the Meinberg standard time string format at 19200/8N1.
      
				
      The University of Erlangen format is preferred. Newer Meinberg GPS receivers can be configured to transmit that format; for older devices, a special firmware version may be available.
      
				
      In this mode some additional GPS receiver status information is also read. However, this requires a point-to-point connection. Mode 18 should be used if the device is accessed by a multidrop connection.
      
				
      Note: mode 7 must not be used with Meinberg PCI cards; use mode 2 instead.

    Actual data formats and setup requirements of the various clocks can be found in NTP PARSE clock data formats.
    
		
    Operation
    
		
    The reference clock support software carefully monitors the state transitions of the receiver. All state changes and exceptional events (such as loss of time code transmission) are logged via the syslog facility. Every hour a summary of the accumulated times for the clock states is listed via syslog.
    
		
    PPS support is only available when the receiver is completely synchronized. The receiver is believed to deliver correct time for an additional period of time after losing synchronization, unless a disruption in time code transmission is detected (possible power loss). The trust period is dependent on the receiver oscillator and thus is a function of clock type.
    
		
    Raw DCF77 pulses can be fed via a level converter to the RXD pin of an RS-232 serial port (pin 3 of a 25-pin connector or pin 2 of a 9-pin connector). The telegrams are decoded and used for synchronization. DCF77 AM receivers can be bought for as little as $25. The accuracy is dependent on the receiver and is somewhere between 2ms (expensive) and 10ms (cheap). Synchronization ceases when reception of the DCF77 signal deteriorates, since no backup oscillator is available as usually found in other reference clock receivers. So it is important to have a good place for the DCF77 antenna. During transmitter shutdowns you are out of luck unless you have other NTP servers with alternate time sources available.
    
		
    In addition to the PPS loopfilter control, a true PPS hardware signal can be utilized via the PPSAPI interface. PPS pulses are usually fed via a level converter to the DCD pin of an RS-232 serial port (pin 8 of a 25-pin connector or pin 1 of a 9-pin connector). To select PPS support, the mode parameter is the mode value as above plus 128. If 128 is not added to the mode value, PPS will be detected to be available but will not be used.
		
    
		
    Hardware PPS support
    
		
    
		
    For PPS to be used, add 128 to the mode parameter.
    
                
    If the PPS signal is fed in from a device different from the device providing the serial communication (/dev/refclock-{0..3}), this device is configured as /dev/refclockpps-{0..3}. This allows the PPS information to be fed in e.g. via the parallel port (if supported by the underlying operation system) and the date/time telegrams to be handled via the serial port.
    
		
    Monitor Data
    
		
    Clock state statistics are written hourly to the syslog service. Online information can be found by examining the clock variables via the ntpq cv command.
    
			Some devices have quite extensive additional information (GPS16x/GPS17x, Trimble). The driver reads out much of the internal GPS data
			and makes it accessible via clock variables. To find out about additional variable names, query for the clock_var_list variable on
			a specific clock association as shown below.
		
    
		
    First let ntpq display the table of associations:
    
		
      ntpq> as
  ind assID status  conf reach auth condition  last_event cnt
  ===========================================================
    1 19556  9154   yes   yes  none falsetick   reachable  5
    2 19557  9435   yes   yes  none  candidat  clock expt  3
    3 19558  9714   yes   yes  none  pps.peer   reachable  1
		
    
		
    Then switch to raw output. This may be required because of display limitations in ntpq/ntpd - so large lists need to be retrieved in several queries.
    
		
      ntpq> raw
  Output set to raw
		
    
		
    Use the cv command to read the list of clock variables of a selected association:
    
		
      ntpq> cv 19557 clock_var_list
		
    
		
    The long output of the command above looks similar to:
    
		
      assID=19557 status=0x0000,
  clock_var_list="type,timecode,poll,noreply,badformat,baddata,fudgetime1,
  fudgetime2,stratum,refid,flags,device,clock_var_list,refclock_time,refclock_status,
  refclock_format,refclock_states,refclock_id,refclock_iomode,refclock_driver_version,
  meinberg_gps_status,gps_utc_correction,gps_message,meinberg_antenna_status,gps_tot_51,
  gps_tot_63,gps_t0a,gps_cfg[1],gps_health[1],gps_cfg[2],gps_health[2],gps_cfg[3],
  gps_health[3],gps_cfg[4],gps_health[4],gps_cfg[5]"
		
    
		
    Then use the cv command again to list selected clock variables. The following command must be entered as a single line:
    
		
      ntpq> cv 19557 refclock_status,refclock_format,refclock_states,refclock_id,
  refclock_iomode,refclock_driver_version,meinberg_gps_status,gps_utc_correction,
  gps_message,meinberg_antenna_status,gps_tot_51,gps_tot_63,gps_t0a,gps_cfg[1],
  gps_health[1],gps_cfg[2],gps_health[2],gps_cfg[3],gps_health[3],gps_cfg[4],
  gps_health[4],gps_cfg[5]
		
    
		
    The output of the command above is wrapped around depending on the screen width and looks similar to:

    Fudge Factors
    
		
    
			
    time1 time
			
    Specifies the time offset calibration factor, in seconds and fraction. The default value depends on the clock type.
			
    time2 time
			
    
				If flag1 is 0, time2 specifies the offset of the PPS signal from the actual time (PPS fine tuning).
			
    
				If flag1 is 1, time2 specifies the number of seconds a receiver with a premium local oscillator can be trusted after losing synchronisation.
			
    stratum stratum
			
    The stratum for this reference clock.
			
    refid refid
			
    The refid for this reference clock.
		
    
		
    
			
    flag1 { 0 | 1 }
			
    If 0, the fudge factor time2 refers to the PPS offset.
			
    If 1, time2 refers to the TRUST TIME.
			
    flag2 { 0 | 1 }
			
    If flag2 is 1, sample PPS on CLEAR instead of on ASSERT.
			
    flag3 { 0 | 1 }
			
    If flag3 is 1, link kernel PPS tracking to this refclock instance.
			
    flag4 { 0 | 1 }
			
    Delete next leap second instead of adding it. (You'll need to wait a bit for that to happen 8-)
		
    
		Note about auxiliary Sun STREAMS modules (SunOS and Solaris):
    
		
    
			
    The timecode of these receivers can be sampled via a STREAMS module in the kernel. (The STREAMS module has been designed for use with Sun systems under SunOS 4.1.x or Solaris 2.3 - 2.8. It can be linked directly into the kernel or loaded via the loadable driver mechanism.) This STREAMS module can be adapted to convert different time code formats. Nowadays the PPSAPI mechanism is usually used.
		
    
		
    Making your own PARSE clocks
    
		
    The parse clock mechanism deviates from the way other NTP reference clocks work. For a short description of how to build parse reference clocks, see making PARSE clocks.

    Trak 8820 GPS Receiver
    
        
    
        
    Synopsis
    
        
    Address: 127.127.2.u
    
            Reference ID: GPS
    
            Driver ID: GPS_TRAK
    
            Serial Port: /dev/traku; 9600 baud, 8-bits, no parity
    
            Features: tty_clk
    
        
    Description
    
        
    This driver supports the Trak 8820 GPS Station Clock. The claimed accuracy at the 1-PPS output is 200-300 ns relative to the broadcast signal; however, in most cases the actual accuracy is limited by the precision of the timecode and the latencies of the serial interface and operating system.
    
        
    For best accuracy, this radio requires the tty_clk line discipline, which captures a timestamp at the * on-time character of the timecode. Using this discipline the jitter is in the order of 1 ms and systematic error about 0.5 ms. If unavailable, the buffer timestamp is used, which is captured at the \r ending the timecode message. This introduces a systematic error of 23 character times, or about 24 ms at 9600 bps, together with a jitter well over 8 ms on Sun IPC-class machines.
    
        
    Using the menus, the radio should be set for 9600 bps, one stop bit and no parity. It should be set to operate in computer (no echo) mode. The timecode format includes neither the year nor leap-second warning.
    
        
    In operation, this driver sends a RQTS\r request to the radio at initialization in order to put it in continuous time output mode. The radio then sends the following message once each second:
    
        
    *RQTS U,ddd:hh:mm:ss.0,q<cr><lf>
on-time = '*'
ddd = day of year
hh:mm:ss = hours, minutes, seconds
q = quality indicator (phase error), 0-6:
     0 > 20 us
     6 > 10 us
     5 > 1 us
     4 > 100 ns
     3 > 10 ns
     2 < 10 ns
    
        The alarm condition is indicated by 0 at Q, which means the radio has a phase error greater than 20 us relative to the broadcast time. The absence of year, DST and leap-second warning in this format is also alarmed.
        
    The continuous time mode is disabled using the RQTX\r request, following which the radio sends a RQTX DONE<cr><lf> response. In the normal mode, other control and status requests are effective, including the leap-second status request RQLS<cr>. The radio responds with RQLS yy,mm,dd<cr><lf>, where yy,mm,dd are the year, month and day. Presumably, this gives the epoch of the next leap second, RQLS 00,00,00 if none is specified in the GPS message. Specified in this form, the information is generally useless and is ignored by the driver.
    
        
    Monitor Data
    
        
    When enabled by the flag4 fudge flag, every received timecode is written as-is to the clockstats file.

    Control Port Sentences
    
		
    The Control (CDU) Port is used to initialize, monitor, and control the receiver. The structure of the control port sentences is based on the NMEA-0183 Standard for Interfacing Marine Electronics Navigation Devices (version 1.5). For more details, please refer to the NMEA-0183 Specification available from the National Marine Electronics Association.
    
		
    Reserved characters are used to indicate the beginning and the end of records in the data stream, and to delimit data fields within a sentence. Only printable ASCII characters (Hex 20 through 7F) may be used in a sentence. Table 2 lists the reserved characters and defines their usage. Table 1 illustrates the general Magnavox proprietary NMEA sentence format.

    Following the start character $, are five characters which constitute the block label of the sentence. For Magnavox proprietary sentences, this label is always PMVXG. The next field after the block label is the sentence type, consisting of three decimal digits.
    
		
    The data, delimited by commas, follows the sentence type. Note that the receiver uses a free-format parsing algorithm, so you need not send the exact number of characters shown in the examples. You will need to use the commas to determine how many bytes of data need to be retrieved.
    
		
    The notation CK shown in Table 1 symbolically indicates the optional checksum in the examples. The checksum is computed by exclusive-ORing all of the bytes between the $ and the * characters. The $, * and the checksum are not included in the checksum computation.
    
		
    Checksums are optional for Control Port input sentences, but are highly recommended to limit the effects of communication errors. Magnavox receivers always generate checksums for Control Port output sentences.
    
		
    ASCII data characters are transmitted in the following format:
    
		
    
			
    
				Data Bits
				8 (msb always 0)
			
    
			
    
				Parity
				None
			
    
			
    
				Stop Bits
				1
			
    
		
    
		
    NULL fields are fields which do not contain any data. They would appear as two commas together in the sentence format, except for the final field. Some Magnavox proprietary sentences require that the format contain NULL fields. mandatory NULL fields are identified by an '*' next to the respective field.

		Generic NMEA GPS Receiver
		
	

	
		
    Generic NMEA GPS Receiver
    
		
    
		
    Synopsis
    
		
    Address: 127.127.20.u
    
			Reference ID: GPS
    
			Driver ID: GPS_NMEA
    
			Serial Port: /dev/gpsu; 4800 - 115200 bps, 8-bits, no parity
    
			Serial Port: /dev/gpsppsu; for just the PPS signal (this is tried first for PPS, before /dev/gpsu)
    
			Serial Port: /dev/gpsu; symlink to server:port (for nmead) Features: tty_clk
    
		
    Description
    
		
    This driver supports GPS receivers with the $GPRMC, $GPGLL, $GPGGA, $GPZDA, and $GPZDG NMEA sentences by default.  Note that Accord's custom NMEA sentence $GPZDG reports using the GPS timescale, while the rest of the sentences report UTC.  The difference between the two is a whole number of seconds which increases with each leap second insertion in UTC.  To avoid problems mixing UTC and GPS timescales, the driver disables processing of UTC sentences once $GPZDG is received.
    
		
    The driver expects the receiver to be set up to transmit at least one supported sentence every second.
    
		
    The accuracy depends on the receiver used. Inexpensive GPS models are available with a claimed PPS signal accuracy of 1 ms or better relative to the broadcast signal. However, in most cases the actual accuracy is limited by the precision of the timecode and the latencies of the serial interface and operating system.
    
		
    If the Operating System supports PPSAPI (RFC 2783), fudge flag1 1 enables its use.
     
    
		
    The various GPS sentences that this driver recognises look like this:

  MM       - Month of the year (1-12)
  YYYY     - Year
  AA.BB    - Denotes the signal strength (should be < 05.00)
  V        - GPS sync status
            '0' => INVALID time,

            '2' => accuracy of +/- 100ns	
  CS       - Checksum
  <cr><lf> - Sentence terminator.
    


    Specific GPS sentences and bitrates may be selected by setting bits of the 'mode' in the server configuration line:
    
    server 127.127.20.x mode X
        bit 0 - process $GPMRC    (value = 1)
        bit 1 - process $GPGGA    (value = 2)
        bit 2 - process $GPGLL    (value = 4)
        bit 4 - process $GPZDA or $GPZDG    (value = 8)
     

    The default (mode 0) is to process all supported sentences, which results in the last received each cycle being used.  Multiple sentences may be selected by adding their mode bit values.  The driver uses 4800 bits per second by default.  Faster bitrates can be selected using bits 4, 5, and 6 of the mode field:

    
		    bits 4/5/6 - select serial bitrate   (0 for 4800 - the default, 16 for 9600, 32 for 19200, 48 for 38400, 64 for 57600, 80 for 115200)
    
		
    The driver will send a $PMOTG,RMC,0000*1D<cr><lf> command each poll interval.  This is not needed on most GPS receivers because they automatically send $GPRMC every second, but helps a Motorola GPS receiver that is otherwise silent.  NMEA devices ignore commands they do not understand.
    
		
    Setting up the Garmin GPS-25XL
    
		Switch off all output with by sending it the following string.
		
    "$PGRMO,,2<cr><lf>"
    
		
    Now switch only $GPRMC on by sending it the following string.
    
		
    "$PGRMO,GPRMC,1<cr><lf>"
    
		
    On some systems the PPS signal isn't switched on by default. It can be switched on by sending the following string.
    
		
    "$PGRMC,,,,,,,,,,,,2<cr><lf>"
    
		
    Monitor Data
    
		
    The GPS sentence that is used is written to the clockstats file and available with ntpq -c clockvar.

    Introduction
    


    This page lists the status words, event messages and error codes used for ntpd reporting and monitoring. Status words are used to display the current status of the running program. There is one system status word and a peer status word for each association. There is a clock status word for each association that supports a reference clock. There is a flash code for each association which shows errors found in the last packet received (pkt) and during protocol processing (peer). These are commonly viewed using the ntpq program.
    


    Significant changes in program state are reported as events. There is one
	set of system events and a set of peer events for each association. In addition,
	there is a set of clock events for each association that supports a reference
	clock. Events are normally reported to the protostats monitoring file
	and optionally to the system log. In addition, if the trap facility is configured,
	events can be reported to a remote program that can page an administrator.
    


    This page also includes a description of the error messages produced by the Autokey protocol. These messages are normally sent to the cryptostats monitoring file.
    


    In the following tables the Code Field is the status or event code assigned and the Message Field a short string used for display and event reporting. The Description field contains a longer explanation of the status or event. Some messages include additional information useful for error diagnosis and performance assessment.
    


    System Status Word
    


    The system status word consists of four fields LI (0-1), Source (2-7), Count (8-11) and Code (12-15). It is reported in the first line of the rv display produced by the ntpq program.

    broadcastdelay seconds
    
			
    The broadcast and multicast modes require a special calibration to determine the network delay between the local and remote servers. Ordinarily, this is done automatically by the initial protocol exchanges between the client and server. In some cases, the calibration procedure may fail due to network or server access controls, for example. This command specifies the default delay to be used under these circumstances. Typically (for Ethernet), a number between 0.003 and 0.007 seconds is appropriate.
    
			
    driftfile driftfile { tolerance ]
    
			
    This command specifies the complete path and name of the file used to record the frequency of the local clock oscillator. This is the same operation as the -f command linke option. If the file exists, it is read at startup in order to set the initial frequency and then updated once per hour or more with the current frequency computed by the daemon. If the file name is specified, but the file itself does not exist, the starts with an initial frequency of zero and creates the file when writing it for the first time. If this command is not given, the daemon will always start with an initial frequency of zero.
    
				
    The file format consists of a single line containing a single floating point number, which records the frequency offset measured in parts-per-million (PPM). The file is updated by first writing the current drift value into a temporary file and then renaming this file to replace the old version. This implies that ntpd must have write permission for the directory the drift file is located in, and that file system links, symbolic or otherwise, should be avoided.
    
				
    The parameter tolerance is the wander threshold to skip writing the new value. If the value of wander computed from recent frequency changes is greater than this threshold the file will be updated once per hour. If below the threshold, the file will not be written.
    
			
    enable [ auth | bclient | calibrate | kernel | monitor | ntp | pps | stats]
    
			disable [ auth | bclient | calibrate | kernel | monitor | ntp | pps | stats ]
    
			
    Provides a way to enable or disable various system options. Flags not mentioned are unaffected. Note that all of these flags can be controlled remotely using the ntpdc utility program.
				
    
					
    auth
    
					
    Enables the server to synchronize with unconfigured peers only if the peer has been correctly authenticated using either public key or private key cryptography. The default for this flag is enable.
    
					
    bclient
    
					
    Enables the server to listen for a message from a broadcast or multicast server, as in the multicastclient command with default address. The default for this flag is disable.
    
					
    calibrate
    
					
    Enables the calibrate feature for reference clocks. The default for this flag is disable.
    
					
    kernel
    
					
    Enables the kernel time discipline, if available. The default for this flag is enable if support is available, otherwise disable.
    
					
    monitor
    
					
    Enables the monitoring facility. See the ntpdc program and the monlist command or further information. The default for this flag is enable.
    
					
    ntp
    
					
    Enables time and frequency discipline. In effect, this switch opens and closes the feedback loop, which is useful for testing. The default for this flag is enable.
    
					
    stats
    
					
    Enables the statistics facility. See the Monitoring Options page for further information. The default for this flag is disable.
    
				
    
				
    
			
    includefile includefile
    
			
    This command allows additional configuration commands to be included from a separate file. Include files may be nested to a depth of five; upon reaching the end of any include file, command processing resumes in the previous configuration file. This option is useful for sites that run ntpd on multiple hosts, with (mostly) common options (e.g., a restriction list).
    
			
    interface [listen | ignore | drop] [all | ipv4 | ipv6 | wildcard | name | address[/prefixlen]]
    
			
    This command controls which network addresses ntpd opens, and whether input is dropped without processing. The first parameter determines the action for addresses which match the second parameter. That parameter specifies a class of addresses, or a specific interface name, or an address. In the address case, prefixlen determines how many bits must match for this rule to apply. ignore prevents opening matching addresses, drop causes ntpd to open the address and drop all received packets without examination. Multiple interface commands can be used. The last rule which matches a particular address determines the action for it. interface commands are disabled if any -I, --interface, -L, or --novirtualips command-line options are used.  If none of those options are used and no interface actions are specified in the configuration file, all available network addresses are opened. The nic command is an alias for interface.
    
			
    leapfile leapfile
    
			
    This command loads the NIST leapseconds file and initializes the leapsecond values for the next leapsecond time, expiration time and TAI offset. The file can be obtained directly from NIST national time servers using ftp as the ASCII file pub/leap-seconds.
    
			
    While not strictly a security function, the Autokey protocol provides means to securely retrieve the current or updated leapsecond values from a server.
    
			
    logconfig configkeyword
    
			
    This command controls the amount and type of output written to the system syslog facility or the alternate logfile log file. All configkeyword keywords can be prefixed with =, + and -, where = sets the syslogmask, + adds and - removes messages. syslog messages can be controlled in four classes (clock, peer, sys and sync). Within these classes four types of messages can be controlled: informational messages (info), event messages (events), statistics messages (statistics) and status messages (status).
    
				
    Configuration keywords are formed by concatenating the message class with the event class. The all prefix can be used instead of a message class. A message class may also be followed by the all keyword to enable/disable all messages of the respective message class. By default, logconfig output is set to allsync.
    
				
    Thus, a minimal log configuration could look like this:
    
				
    logconfig=syncstatus +sysevents
    
						
    This would just list the synchronizations state of ntpd and the major system events. For a simple reference server, the following minimum message configuration could be useful:
    
				
    logconfig allsync +allclock
    
				
    This configuration will list all clock information and synchronization information. All other events and messages about peers, system events and so on is suppressed.
    
			
    logfile logfile
    
			
    This command specifies the location of an alternate log file to be used instead of the default system syslog facility. This is the same operation as the -l command line option.
    
			
    phone dial1 dial2 ...
    
			
    This command is used in conjunction with the ACTS modem driver (type 18). The arguments consist of a maximum of 10 telephone numbers used to dial USNO, NIST or European time services. The Hayes command ATDT is normally prepended to the number, which can contain other modem control codes as well.
    
			
    saveconfigdir directory_path
    
			
    Specify the directory in which to write configuration snapshots requested with ntpq's saveconfig command.  If saveconfigdir does not appear in the configuration file, saveconfig requests are rejected by ntpd.
    
			
    setvar variable [default]
    
			
    This command adds an additional system variable. These variables can be used to distribute additional information such as the access policy. If the variable of the form name = value is followed by the default keyword, the variable will be listed as part of the default system variables (ntpq rv command). These additional variables serve informational purposes only. They are not related to the protocol other that they can be listed. The known protocol variables will always override any variables defined via the setvar mechanism. There are three special variables that contain the names of all variable of the same group. The sys_var_list holds the names of all system variables. The peer_var_list holds the names of all peer variables and the clock_var_list holds the names of the reference clock variables.
    
			
    tinker [ allan allan | dispersion dispersion | freq freq | huffpuff huffpuff | panic panic | step step | stepout stepout ]
    
			
    This command alters certain system variables used by the clock discipline algorithm. The default values of these variables have been carefully optimized for a wide range of network speeds and reliability expectations. Very rarely is it necessary to change the default values; but, some folks can't resist twisting the knobs. The options are as follows:
    
				
    
					
    allan allan
    
					
    Spedifies the Allan intercept, which is a parameter of the PLL/FLL clock discipline algorithm, in seconds with default 1500 s.
    
					
    dispersion dispersion
    
					
    Specifies the dispersion increase rate in parts-per-million (PPM) with default 15 PPM.
    
					
    freq freq
    
					
    Spedifies the frequency offset in parts-per-million (PPM) with default the value in the frequency file.
    
					
    huffpuff huffpuff
    
					
    Spedifies the huff-n'-puff filter span, which determines the most recent interval the algorithm will search for a minimum delay. The lower limit is 900 s (15 m), but a more reasonable value is 7200 (2 hours).
    
					
    panic panic
    
					
    Spedifies the panic threshold in seconds with default 1000 s. If set to zero, the panic sanity check is disabled and a clock offset of any value will be accepted.
    
					
    step step
    
					
    Spedifies the step threshold in seconds. The default without this command
						is 0.128 s. If set to zero, step adjustments will never
						occur. Note: The kernel time discipline is disabled if
						the step threshold is set to zero or greater than 0.5
						s.
    
					
    stepout stepout
    
					
    Specifies the stepout threshold in seconds. The default without this
						command is 900 s.  If set to zero, popcorn spikes will
						not be suppressed.
    
			
    
			
    tos [ beacon beacon | ceiling ceiling | cohort {0 | 1} | floor floor | maxclock maxclock | maxdist maxdist | minclock minclock | mindist mindist | minsane minsane | orphan stratum ]
    
			
    This command alters certain system variables used by the the clock selection and clustering algorithms. The default values of these variables have been carefully optimized for a wide range of network speeds and reliability expectations. Very rarely is it necessary to change the default values; but, some folks can't resist twisting the knobs. It can be used to select the quality and quantity of peers used to synchronize the system clock and is most useful in dynamic server discovery schemes. The options are as follows:
    
				
    
					
    beacon beacon
    
					
    The manycast server sends packets at intervals of 64 s if less than  maxclock servers are available. Otherwise, it sends packets at the beacon interval in seconds. The default is 3600 s. See the Automatic Server Discovery page for further details.
    
					
    ceiling ceiling
    
					
    Specify the maximum stratum (exclusive) for acceptable server packets. The default is 16. See the Automatic Server Discovery page for further details.
    
					
    cohort { 0 | 1 }
    
					
    Specify whether (1) or whether not (0) a server packet will be accepted for the same stratum as the client. The default is 0. See the Automatic Server Discovery page for further details.
    
					
    floor floor
    
					
    Specify the minimum stratum (inclusive) for acceptable server packest. The default is 1. See the Automatic Server Discovery page for further details.
    
					
    maxclock maxclock
    
					
    Specify the maximum number of servers retained by the server discovery schemes. The default is 10. See the Automatic Server Discovery page for further details.
    
					
    maxdist maxdistance
    
					
    Specify the synchronization distance threshold used by the clock selection algorithm. The default is 1.5 s. This determines both the minimum number of packets to set the system clock and the maximum roundtrip delay. It can be decreased to improve reliability or increased to synchronize clocks on the Moon or planets.
    
					
    minclock minclock
    
					
    Specify the number of servers used by the clustering algorithm as the minimum to include on the candidate list. The default is 3. This is also the number of servers to be averaged by the combining algorithm.
    
					
    mindist mindistance
    
					
    Specify the minimum distance used by the selection and anticlockhop
						algorithm. Larger values increase the tolerance for outliers;
						smaller values increase the selectivity. The default is .001 s. In some
						cases, such as reference clocks with high jitter and a PPS signal, it is
						useful to increase the value to insure the intersection interval is
						always nonempty.
    
					
    minsane minsane
    
					
    Specify the number of servers used by the selection algorithm as the minimum to set the system clock. The default is 1 for legacy purposes; however, for critical applications the value should be somewhat higher but less than minclock.
    
					
    orphan stratum
    
					
    Specify the orphan stratum with default 16. If less than 16 this is the stratum assumed by the root servers. See the Association Management page for further details.
    
			
    
			
    trap host_address [port port_number] [interface interfSace_address]
    
			
    This command configures a trap receiver at the given host address and port number for sending messages with the specified local interface address. If the port number is unspecified, a value of 18447 is used. If the interface address is not specified, the message is sent with a source address of the local interface the message is sent through. Note that on a multihomed host the interface used may vary from time to time with routing changes.
    
				
    The trap receiver will generally log event messages and other information from the server in a log file. While such monitor programs may also request their own trap dynamically, configuring a trap receiver will ensure that no messages are lost when the server is started.

    Description
    


    This program generates cryptographic data files used by the NTPv4 authentication
	and identity schemes. It can generate  message digest keys used in symmetric
	key cryptography and, if the OpenSSL software library has been installed,
	it can generate host keys, sign keys, certificates and identity keys used
	by the Autokey public key cryptography. The message digest keys file is generated
	in a format compatible with NTPv3. All other files are in PEM-encoded printable
	ASCII format so they can be embedded as MIME attachments in mail to other
	sites.
    


    When used to generate message digest keys, the program produces a file containing
	ten pseudo-random printable ASCII strings suitable for the MD5 message digest
	algorithm included in the distribution. If the OpenSSL library is installed,
	it produces an additional ten hex-encoded random bit strings suitable for
	the SHA1 and other message digest algorithms. Printable ASCII keys can have
	length from one to 20 characters, inclusive. Bit string keys have length
	20 octets (40 hex characters). All keys are 160 bits in length.
    

     The file can be edited later with
	purpose-chosen passwords for the ntpq and ntpdc programs.
	Each line of the file contains three fields, first an integer between 1 and
	65534, inclusive, representing the key identifier used in the server and peer configuration
	commands. Next is the key type for the message digest algorithm,
	which in the absence of the OpenSSL library should be the string MD5 to
	designate the  MD5 message digest algorithm.
	If the OpenSSL library is installed, the key type can be any message digest
	algorithm supported by that library. However, if compatibility with FIPS
	140-2 is required, the key type must be either SHA or SHA1.Finally
	is the key itself as a printable ASCII string excluding the space and # characters.
	If not greater than 20 characters in length, the string is the key itself;
	otherwise, it is interpreted as a hex-encoded bit string. As is
	custom, # and the remaining characters on the line are ignored. Later, this
	file can be edited to include the passwords for the ntpq and ntpdc utilities.
	If this is the only need, run ntp-keygen with the -M option
	and disregard the remainder of this page. 
    

    The remaining generated files are compatible with other OpenSSL applications and other Public Key Infrastructure (PKI) resources. Certificates generated by this program should be compatible with extant industry practice, although some users might find the interpretation of X509v3 extension fields somewhat liberal. However, the identity keys are probably not compatible with anything other than Autokey.
    


    Most files used by this program are encrypted using a private password. The -p option specifies the password for local files and the -q option the password for files sent to remote sites. If no local password is specified, the host name returned by the Unix gethostname() function, normally the DNS name of the host, is used. If no remote password is specified, the local password is used.
    


    The pw option of the crypto configuration command specifies the read password for previously encrypted files. This must match the local password used by this program. If not specified, the host name is used. Thus, if files are generated by this program without password, they can be read back by ntpd without password, but only on the same host.
    


    All files and links are usually installed   in the  directory /usr/local/etc,
	which is normally in a shared filesystem in NFS-mounted networks and cannot
	be changed by shared clients. The location of the keys directory can be changed
	by the keysdir configuration command in such cases. Normally, encrypted
	files for each host are generated by that host and used only by that host,
	although exceptions exist as noted later on this page.
    


    This program directs commentary and error messages to the standard error stream stderr and remote files to the standard output stream stdout where they can be piped to other applications or redirected to a file. The names used for generated files and links all begin with the string ntpkey and include the file type, generating host and filestamp, as described in the Cryptographic Data Files section below
    


    Running the Program
    


    To test and gain experience with Autokey concepts, log in as root and change to the keys directory, usually /usr/local/etc. When run for the first time, or if all files with names beginning ntpkey have been removed, use the ntp-keygen command without arguments to generate a default RSA host key and matching RSA-MD5 certificate with expiration date one year hence. If run again, the program uses the existing keys and parameters and generates only a new certificate with new expiration date one year hence; however, the certificate is not generated if the -e or -q options are  present.
    


    Run the command on as many hosts as necessary. Designate one of them as the trusted host (TH) using ntp-keygen with the -T option and configure it to synchronize from reliable Internet servers. Then configure the other hosts to synchronize to the TH directly or indirectly. A certificate trail is created when Autokey asks the immediately ascendant host towards the TH to sign its certificate, which is then provided to the immediately descendant host on request. All group hosts should have acyclic certificate trails ending on the TH.
    


    The host key is used to encrypt the cookie when required and so must be RSA type. By default, the host key is also the sign key used to encrypt signatures. A different sign key can be assigned using the -S option and this can be either RSA or DSA type. By default, the signature message digest type is MD5, but any combination of sign key type and sign digest type supported by the OpenSSL library can be specified using the -c option. At the moment, legacy considerations require the NTP packet header digest type to be MD5.
    


    Trusted Hosts and Secure Groups
    


    As described on the Authentication Options page, an NTP secure group consists of one or more low-stratum THs as the root from which all other group hosts derive synchronization directly or indirectly. For authentication purposes all hosts in a group must have the same group name specified by the -i option and matching the ident option of the crypto configuration command. The group name is used in the subject and issuer fields of trusted, self-signed certificates and when constructing the file names for identity keys. All hosts must have different host names, either the default host name or as specified by the -s option and matching the host option of the crypto configuration command. Most installations need not specify the -i option nor the host option. Host names are used in the subject and issuer fields of self-signed, nontrusted certificates and when constructing the file names for host and sign keys and certificates. Host and group names are used only for authentication purposes and have nothing to do with DNS names.
    


    Identity Schemes
    


    As described on the Authentication Options page, there are five identity schemes, three of which - IFF, GQ and MV - require identity keys specific to each scheme. There are two types of files for each scheme, an encrypted keys file and a nonencrypted parameters file, which usually contains a subset of the keys file. In general, NTP secondary servers operating as certificate signing authorities (CSA) use the keys file and clients use the parameters file. Both files are generated by the TA operating as a certificate authority (CA) on behalf of all servers and clients in the group.
    


    The parameters files are public; they can be stored in a public place and
	sent in the clear. The keys files are encrypted with the local password. To
	retrieve the keys file, a host can send a mail request to the TA including its
	local password. The TA encrypts the keys file with this password and returns
	it as an attachment. The attachment is then copied intact to the keys directory
	with name given in the first line of the file, but all in lower case and with
	the filestamp deleted. Alternatively, the parameters file can be retrieved from
	a secure web site.
    


    For example, the TA generates default host key, IFF keys and trusted certificate using the command
    


    ntp-keygen -p local_passwd -T -I -igroup_name
    


    Each group host generates default host keys and nontrusted certificate use
	the same command line but omitting the -i option. Once these media
	have been generated, the TA can then generate the public parameters using the
	command
    


    ntp-keygen -p local_passwd -e >parameters_file
    


    where the -e option redirects the unencrypted parameters to the standard output stream for a mail application or stored locally for later distribution. In a similar fashion the -q option redirects the encrypted server keys to the standard output stream.
    


    Command Line Options
    


    


    -c [ RSA-MD2 | RSA-MD5 | RSA-SHA | RSA-SHA1 | RSA-MDC2 | RSA-RIPEMD160 | DSA-SHA | DSA-SHA1 ]
    

    Select certificate and message digest/signature encryption scheme. Note that
	RSA schemes must be used with a RSA sign key and DSA schemes must be used
	with a DSA sign key. The default without this option is RSA-MD5. If
	compatibility with FIPS 140-2 is required, either the DSA-SHA or DSA-SHA1 scheme
	must be used.
    


    -d
    

    Enable debugging. This option displays the cryptographic data produced for eye-friendly billboards.
    


    -e
    

    Extract the IFF or GQ public parameters from the IFFkey or GQkey keys file previously specified. Send the unencrypted data to the standard output stream stdout. While the IFF parameters do not reveal the private group key,  the GQ parameters  should be used with caution, as they include the group key. Use the -q option with password instead. Note: a new certificate is not generated when this option is present. This allows multiple commands with this option but  without disturbing existing media.
    


    -G
    

    Generate a new encrypted GQ key file   and link for the Guillou-Quisquater
	(GQ) identity scheme.
    


    -H
    

    Generate a new encrypted RSA public/private host key file and link.
	Note that if the sign key is the same as the host key, generating a new host
	key invalidates all certificates signed with the old host key.
    


    -i group
    

    Set the group name to group. This is used in the identity file names. It must match the group name specified in the ident option of the crypto configuration command.
    


    -I
    

    Generate a new encrypted IFF key file and link for the Schnorr (IFF) identity scheme.
    


    -m modulus
    

    Set the modulus for generating files to modulus bits. The modulus defaults to 512, but can be set from 256 (32 octets) to 2048 (256 octets).
    


    -M
    

    Generate a new MD5 key file containing 16, 128-bit pseudo-random keys for
	symmetric cryptography..
    


    -P
    

    Generate a new private certificate used by the PC identity scheme. By default, the program generates public certificates. Note: the PC identity scheme is not recommended for new installations.
    


    -p passwd
    

    Set the password for reading and writing encrypted files to passwd. By default, the password is the host name.
    


    -q passwd
    

    Extract the encrypted IFF or GQ server keys from the IFFkey or GQkey key file previously generated. The data are sent to the standard output stream stdout. Set the password for writing the data, which is also the password to read the data file in another host. By default, the password is the host name. Note: a new certificate is not generated when this option is present. This allows multiple commands with this option but without disturbing existing media.
    


    -S [ RSA | DSA ]
    

    Generate a new sign key of the specified type. By default, the sign key is
	the host key and has the same type. If compatibly with FIPS 140-2 is required,
	the sign key type must be DSA. Note that generating a new sign key
	invalidates all certificates signed with the old sign key.
    


    -s host
    

    Set the host name to host. This is used in the host and sign key file names. It must match the host name specified in the host option of the crypto configuration command.
    


    -T
    

    Generate a trusted certificate. By default, the program generates nontrusted certificates.
    


    -V nkeys
    

    Generate server parameters MV and nkeys client keys for the Mu-Varadharajan (MV)  identity scheme. Note: support for this option should be considered a work in progress.
    

    


    Random Seed File
    


    All cryptographically sound key generation schemes must have means to randomize the entropy seed used to initialize the internal pseudo-random number generator used by the OpenSSL library routines. If a site supports ssh, it is very likely that means to do this are already available. The entropy seed used by the OpenSSL library is contained in a file, usually called .rnd, which must be available when starting the ntp-keygen program or ntpd daemon.
    


    The OpenSSL library looks for the file using the path specified by the RANDFILE environment variable in the user home directory, whether root or some other user. If the RANDFILE environment variable is not present, the library looks for the .rnd file in the user home directory. Since both the ntp-keygen program and ntpd daemon must run as root, the logical place to put this file is in /.rnd or /root/.rnd. If the file is not available or cannot be written, the program exits with a message to the system log.
    

    On systems that provide /dev/urandom, the randomness device is used instead and the file specified by the randfile subcommand or the RANDFILE environment variable is ignored.
    


    Cryptographic Data Files
    


    File and link names are in the form ntpkey_key_name.fstamp, where key is the key or parameter type, name is the host or group name and fstamp is the filestamp (NTP seconds) when the file was created). By convention, key fields in generated file names include both upper and lower case alphanumeric characters, while key fields in generated link names include only lower case characters. The filestamp is not used in generated link names.
    


    The key type is a string defining the cryptographic function. Key types include public/private keys host and sign, certificate cert and several challenge/response key types. By convention, files used for challenges have a par subtype, as in the IFF challenge IFFpar, while files for responses have a key subtype, as in the GQ response GQkey.
    


    All files begin with two nonencrypted lines. The first line contains the file name in the format ntpkey_key_host.fstamp. The second line contains the datestamp in conventional Unix date format. Lines beginning with # are ignored.
    


    The remainder of the file contains cryptographic data encoded first using ASN.1 rules, then encrypted using the DES-CBC algorithm and given password and finally written in PEM-encoded printable ASCII text preceded and followed by MIME content identifier lines.
    


    The format of the symmetric keys file is somewhat different than the other files in the interest of backward compatibility. Since DES-CBC is deprecated in NTPv4, the only key format of interest is MD5 alphanumeric strings. Following the header the keys are entered one per line in the format
    


    keyno type key
    


    where keyno is a positive integer in the range 1-65,535, type is the string MD5 defining the key format and key is the key itself, which is a printable ASCII string 16 characters or less in length. Each character is chosen from the 93 printable characters in the range 0x21 through 0x7f excluding space and the '#' character.
    


    Note that the keys used by the ntpq and ntpdc programs are checked against passwords requested by the programs and entered by hand, so it is generally appropriate to specify these keys in human readable ASCII format.
    


    The ntp-keygen program generates a MD5 symmetric keys file ntpkey_MD5key_hostname.filestamp. Since the file contains private shared keys, it should be visible only to root and distributed by secure means to other subnet hosts. The NTP daemon loads the file ntp.keys, so ntp-keygen installs a soft link from this name to the generated file. Subsequently, similar soft links must be installed by manual or automated means on the other subnet hosts. While this file is not used with the Autokey Version 2 protocol, it is needed to authenticate some remote configuration commands used by the ntpq and ntpdc utilities.
    


    Bugs
    


    It can take quite a while to generate some cryptographic values, from one to several minutes with modern architectures such as UltraSPARC and up to tens of minutes to an hour with older architectures such as SPARC IPC.

    The baby panda was scanned at University College London and used as a FAX test image for a demonstration of the DARPA Atlantic SATNET Program and the first transatlantic Internet connection in 1978. The computing system used for that demonstration was called the Fuzzball. As it happened, this was also the first Internet multimedia presentation and the first to use NTP in regular operation. The image was widely copied and used for testing purpose throughout much of the 1980s.

    For the rank amateur the sheer volume of the documentation collection must be intimidating. However, it doesn't take much to fly the ntpd daemon with a simple configuration where a workstation needs to synchronize to some server elsewhere in the Internet. The first thing is to build the distribution for the particular workstation and install in the usual place. The Building and Installing the Distribution page describes how to do this.
    
		
    While it is possible that certain configurations do not need a configuration file, most do. The file, called by default /etc/ntp.conf, need only contain one command specifying a remote server, for instance
    
		
    server foo.bar.com
    
		
    Choosing an appropriate remote server is somewhat of a black art, but a
			suboptimal choice is seldom a problem. The simplest is to use the
			Server Pool Scheme on the Automatic Server Discovery page. There
			are about two dozen public time servers operated by the National
			Institutes of Science and Technology (NIST), US
			Naval Observatory (USNO),  Canadian
			Metrology Centre (CMC) and many others available on the Internet. Lists
			of public primary and secondary NTP servers maintained on the Public
			NTP Time Servers page, which is updated frequently.The lists are sorted
			by country and, in the case of the US, by state. Usually, the best
			choice is the nearest in geographical terms, but the terms of engagement
			specified in each list entry should be carefully respected.
    
	
    During operation ntpd measures and corrects for incidental clock frequency error and occasionally writes the current value to a file specified by the
    
		
    driftfile /etc/ntp.drift
    
		
    configuration command. If ntpd is stopped and restarted, it initializes the frequency from this file and avoids the potentially lengthy interval to relearn the correction.
    
		
    That's all there is to it, unless some problem in network connectivity or local operating system configuration occurs. The most common problem is some firewall between the workstation and server. System administrators should understand NTP uses UDP port 123 as both the source and destination port and that NTP does not involve any operating system interaction other than to set the system clock. While almost all modern Unix systems have included NTP and UDP port 123 defined in the services file, this should be checked if ntpd fails to come up at all.
    
		
    The best way to confirm NTP is working is using the ntpq utility, although the ntpdc utility may be useful in extreme cases. See the documentation pages for further information. Don't forget to check for  system log messages. In the most extreme cases the -d option on the ntpd command line results in a blow-by-blow trace of the daemon operations. While the trace output can be cryptic, to say the least, it gives a general idea of what the program is doing and, in particular, details the arriving and departing packets and any errors found.

    You have come here because you found a cryptic message in the system log. This page by no means lists all messages that might be found, since new ones come and old ones go. Generally, however, the most common ones will be found here. They are listed by program module and log severity code in bold: LOG_ERR, LOG_NOTICE and LOG_INFO.
    
		
    Most of the time LOG_ERR messages are fatal, but often ntpd limps onward in the hopes of discovering more errors. The LOG_NOTICE messages usually mean the time has changed or some other condition that probably should be noticed. The LOG_INFO messages usually say something about the system operations, but do not affect the time.
    
		
    In the following a '?' character stands for text in the message. The meaning should be clear from context.

    There is a problem with the identity scheme. Operation cannot proceed untill the problem is fixed. Usually errors are due to misconfiguration or an orphan association. If the latter, ntpd will usually time out and recover by itself.
			
    crypto_cert: wrong PEM type ?
			
    The certificate does not have MIME type CERTIFICATE. You are probably using the wrong type from OpenSSL or an external certificate authority.
			
    crypto_ident: no compatible identity scheme found
			
    Configuration error. The server and client identity schemes are incompatible.
			
    crypto_tai: kernel TAI update failed
			
    The kernel does not support this function. You may need a new kernel or patch.
			
    crypto_tai: leapseconds file ? error ?
			
    The leapseconds file is corrupt. Obtain the latest file from time.nist.gov.

    Building and Installing the Distribution
    
		
    It is not possible in a software distribution such as this to support every individual computer and operating system with a common executable, even with the same system but different versions and options. Therefore, it is necessary to configure, build and install for each system and version. In almost all cases, these procedures are completely automatic, The user types ./configure, make and install in that order and the autoconfigure system does the rest. There are some exceptions, as noted below and on the Hints and Kinks pages.
    
		
    If available, the OpenSSL library from http://www.openssl.org is used to support public key cryptography. The library must be built and installed prior to building NTP. The procedures for doing that are included in the OpenSSL documentation. The library is found during the normal NTP configure phase and the interface routines compiled automatically. Only the libcrypto.a library file and openssl header files are needed. If the library is not available or disabled, this step is not required.
    
		
    The Build Options page describes a number of options that determine whether debug support is included, whether and which reference clock drivers are included and the locations of the executables and library files, if not the default. By default debugging options and all reference clock drivers are included.
    
		
    Building and Installing for Unix
    
		
    This distribution uses common compilers and tools that come with most Unix distributions. Not all of these tools exist in the standard distribution of modern Unix versions (compilers are likely to be an add-on product). If this is the case, consider using the GNU tools and gcc compiler included as freeware in some systems. For a successful build, all of these tools should be accessible via the current path.
    
		
    The first thing to do is uncompress the distribution and extract the source tree. In the distribution base directory use the ./configure command to perform an automatic configuration procedure. This command inspects the hardware and software environment and configures the build process accordingly. Use the make command to compile and link the distribution and the install command to install the executables by default in /usr/local/bin.
    
		
    If your site supports multiple architectures and uses NFS to share files, you can use a single source tree to build executables for multiple architectures. While running on a particular architecture, change to the base directory and create a subdirectory using a command like mkdir A.machine, which will create an architecture-specific directory, then change to this directory and mumble ../configure. The remaining steps are the same whether building in the base directory or in the subdirectory.
    
		
    Building and Installing for Windows
    
		
    NTP supports Windows Vista, XP, NT4 and 2000 systems. See the NTP 4.x for Windows NT page for directions to compile the sources and install the executables. A precompiled executable is available.
    
		
    Configuration
    
		
    You are now ready to configure the daemon. You will need to create a NTP configuration file by default in /etc/ntp.conf. Newbies should see the Quick Start page for orientation. Seasoned veterans can start with the ntpd - Network Time Protocol (NTP) daemon page and move on to the specific configuration option pages from there.
    
		
    If You Have Problems
    
		
    If you have problems with your hardware and software environment (e.g. operating system-specific issues), browse the Hints and Kinks pages. For other problems a tutorial on debugging technique is in the NTP Debugging Technique page. A list of important system log messages is on the ntpd System Log Messages page.
    
		
    The first line of general assistance is the NTP web site www.ntp.org and the helpful documents resident there. Requests for assistance of a general nature and of interest to other timekeepers should be sent to the NTP newsgroup comp.protocols.time.ntp.
    
		
    Users are invited to report bugs and offer suggestions via the NTPáBug Reporting Procedures page.
    
		
    Additional make commands
    
		
    
			
    make clean
			
    Cleans out object files, programs and temporary files.
			
    make distclean
			
    Does the work of clean, but cleans out all directories in preparation for a new distribution release.
			
    make dist
			
    Does the work of make distclean, but constructs compressed tar files for distribution. You must have GNU automake to perform this function.

# ------------------------------------
# compare this configure script's cache version stamp with the stamp
# saved by the prior run in config.cache.  If they differ, clear all
# cache variables to avoid using results cached with a script that
# is known to differ in a cache-invalidating manner.
#
# Note: use immediately following AC_INIT in configure.ac, as clearing
# all _cv_ variables only makes sense immediately after loading, before
# use or modification.
#
# It is assumed that parent configure.ac files which use
# AC_CONFIG_SUBDIR to invoke child configure.ac files have used 
# NTP_CACHEVERSION if any children do.  The top-level configure script
# will clear a previous cache lacking any saved cache version number,
# while children do not.  The reason is the children can rely on the
# parent having cleared any cache variables predating this mechanism.
# Therefore the child can rely on the config.cache generated by the
# parent on the first run despite not finding its version stamp
# previously saved.  In this case top-level means a configure script
# not invoked by another configure script in its parent directory.

# serial 5 lt~obsolete.m4

# These exist entirely to fool aclocal when bootstrapping libtool.
#
# In the past libtool.m4 has provided macros via AC_DEFUN (or AU_DEFUN)
# which have later been changed to m4_define as they aren't part of the
# exported API, or moved to Autoconf or Automake where they belong.
#
# The trouble is, aclocal is a bit thick.  It'll see the old AC_DEFUN
# in /usr/share/aclocal/libtool.m4 and remember it, then when it sees us
# using a macro with the same name in our local m4/libtool.m4 it'll
# pull the old libtool.m4 in (it doesn't see our shiny new m4_define
# and doesn't know about Autoconf macros at all.)
#
# So we provide this file, which has a silly filename so it's always
# included after everything else.  This provides aclocal with the
# AC_DEFUNs it wants, but when m4 processes it, it doesn't do anything
# because those macros already exist, or will be overwritten later.
# We use AC_DEFUN over AU_DEFUN for compatibility with aclocal-1.6. 
#
# Anytime we withdraw an AC_DEFUN or AU_DEFUN, remember to add it here.
# Yes, that means every name once taken will need to remain here until
# we give up compatibility with versions before 1.7, at which point
# we need to keep only those names which we still refer to.

# This is to help aclocal find these macros, as it can't see m4_define.

The master copy of this information can be found at:

 http://support.ntp.org/Dev/MaintainerIssues#How_to_work_on_a_bug_using_BitKe

If you are going to patch both ntp-stable and ntp-dev
please do it this way:

 > cd ntp-stable
 > (make and test your changes to ntp-stable first)
 > (commit your changes to ntp-stable)
 > cd ../ntp-dev
 > bk pull ../ntp-stable	(get your changes from ntp-stable)
 > (resolve any problems and test your changes)
 > (commit your changes to ntp-dev)

With the current release of bitkeeper it is *much* easier to move changes
from ntp-stable to ntp-dev than it is to move changes from ntp-dev to
ntp-stable.

If you make your changes in the above order and then submit them,
it will be trivial to apply your patches.

Otherwise, it will be much more difficult to apply your patches.

You are pretty much done now if your repos are on pogo.udel.edu.

If these patches are for a bugzilla issue, mark the issue as Resolved/READY
with a comment of "Please pick up the patches in pogo:/wherever"

---

Please read (and follow) the previous section if you want to submit
patches for both ntp-stable and ntp-dev.

If you cannot easily get your patches to pogo, you may submit patches
via the 'bk send' command:

 > cd REPO
 > bk citool	(or bk ci ... ;  bk commit ... )
 > bk pull	# make sure your repo is up-to-date
 > bk send -d -ubk://www.ntp.org/home/bk/REPO - > file-containing-the-patch
 > bk receive -vv -a < file-containing-the-patch
		# Sanity check.

 # Open a bugzilla item at 

 # After the bug is opened, visit the bug and attach file-containing-the-patch

 * Program to generate cryptographic keys for ntp clients and servers
 *
 * This program generates password encrypted data files for use with the
 * Autokey security protocol and Network Time Protocol Version 4. Files
 * are prefixed with a header giving the name and date of creation
 * followed by a type-specific descriptive label and PEM-encoded data
 * structure compatible with programs of the OpenSSL library.
 *
 * All file names are like "ntpkey__.", where
 *  is the file type,  the generating host name and
 *  the generation time in NTP seconds. The NTP programs
 * expect generic names such as "ntpkey__whimsy.udel.edu" with the
 * association maintained by soft links. Following is a list of file
 * types; the first line is the file name and the second link name.
 *
 * ntpkey_MD5key_.
 * 	MD5 (128-bit) keys used to compute message digests in symmetric
 *	key cryptography
 *
 * ntpkey_RSAhost_.
 * ntpkey_host_
 *	RSA private/public host key pair used for public key signatures
 *
 * ntpkey_RSAsign_.
 * ntpkey_sign_
 *	RSA private/public sign key pair used for public key signatures
 *
 * ntpkey_DSAsign_.
 * ntpkey_sign_
 *	DSA Private/public sign key pair used for public key signatures
 *
 * Available digest/signature schemes
 *
 * RSA:	RSA-MD2, RSA-MD5, RSA-SHA, RSA-SHA1, RSA-MDC2, EVP-RIPEMD160
 * DSA:	DSA-SHA, DSA-SHA1
 *
 * ntpkey_XXXcert_.
 * ntpkey_cert_
 *	X509v3 certificate using RSA or DSA public keys and signatures.
 *	XXX is a code identifying the message digest and signature
 *	encryption algorithm
 *
 * Identity schemes. The key type par is used for the challenge; the key
 * type key is used for the response.
 *
 * ntpkey_IFFkey_.
 * ntpkey_iffkey_
 *	Schnorr (IFF) identity parameters and keys
 *
 * ntpkey_GQkey_.,
 * ntpkey_gqkey_
 *	Guillou-Quisquater (GQ) identity parameters and keys
 *
 * ntpkey_MVkeyX_.,
 * ntpkey_mvkey_
 *	Mu-Varadharajan (MV) identity parameters and keys
 *
 * Note: Once in a while because of some statistical fluke this program
 * fails to generate and verify some cryptographic data, as indicated by
 * exit status -1. In this case simply run the program again. If the
 * program does complete with exit code 0, the data are correct as
 * verified.
 *
 * These cryptographic routines are characterized by the prime modulus
 * size in bits. The default value of 512 bits is a compromise between
 * cryptographic strength and computing time and is ordinarily
 * considered adequate for this application. The routines have been
 * tested with sizes of 256, 512, 1024 and 2048 bits. Not all message
 * digest and signature encryption schemes work with sizes less than 512
 * bits. The computing time for sizes greater than 2048 bits is
 * prohibitive on all but the fastest processors. An UltraSPARC Blade
 * 1000 took something over nine minutes to generate and verify the
 * values with size 2048. An old SPARC IPC would take a week.
 *
 * The OpenSSL library used by this program expects a random seed file.
 * As described in the OpenSSL documentation, the file name defaults to
 * first the RANDFILE environment variable in the user's home directory
 * and then .rnd in the user's home directory.

/*
 ***********************************************************************
 *								       *
 * The following routines implement the Schnorr (IFF) identity scheme  *
 *								       *
 ***********************************************************************
 *
 * The Schnorr (IFF) identity scheme is intended for use when
 * certificates are generated by some other trusted certificate
 * authority and the certificate cannot be used to convey public
 * parameters. There are two kinds of files: encrypted server files that
 * contain private and public values and nonencrypted client files that
 * contain only public values. New generations of server files must be
 * securely transmitted to all servers of the group; client files can be
 * distributed by any means. The scheme is self contained and
 * independent of new generations of host keys, sign keys and
 * certificates.
 *
 * The IFF values hide in a DSA cuckoo structure which uses the same
 * parameters. The values are used by an identity scheme based on DSA
 * cryptography and described in Stimson p. 285. The p is a 512-bit
 * prime, g a generator of Zp* and q a 160-bit prime that divides p - 1
 * and is a qth root of 1 mod p; that is, g^q = 1 mod p. The TA rolls a
 * private random group key b (0 < b < q) and public key v = g^b, then
 * sends (p, q, g, b) to the servers and (p, q, g, v) to the clients.
 * Alice challenges Bob to confirm identity using the protocol described
 * below.
 *
 * How it works
 *
 * The scheme goes like this. Both Alice and Bob have the public primes
 * p, q and generator g. The TA gives private key b to Bob and public
 * key v to Alice.
 *
 * Alice rolls new random challenge r (o < r < q) and sends to Bob in
 * the IFF request message. Bob rolls new random k (0 < k < q), then
 * computes y = k + b r mod q and x = g^k mod p and sends (y, hash(x))
 * to Alice in the response message. Besides making the response
 * shorter, the hash makes it effectivey impossible for an intruder to
 * solve for b by observing a number of these messages.
 * 
 * Alice receives the response and computes g^y v^r mod p. After a bit
 * of algebra, this simplifies to g^k. If the hash of this result
 * matches hash(x), Alice knows that Bob has the group key b. The signed
 * response binds this knowledge to Bob's private key and the public key
 * previously received in his certificate.

 * The following routines implement the Guillou-Quisquater (GQ)        *
 * identity scheme                                                     *

 ***********************************************************************
 *
 * The Guillou-Quisquater (GQ) identity scheme is intended for use when
 * the certificate can be used to convey public parameters. The scheme
 * uses a X509v3 certificate extension field do convey the public key of
 * a private key known only to servers. There are two kinds of files:
 * encrypted server files that contain private and public values and
 * nonencrypted client files that contain only public values. New
 * generations of server files must be securely transmitted to all
 * servers of the group; client files can be distributed by any means.
 * The scheme is self contained and independent of new generations of
 * host keys and sign keys. The scheme is self contained and independent
 * of new generations of host keys and sign keys.
 *
 * The GQ parameters hide in a RSA cuckoo structure which uses the same
 * parameters. The values are used by an identity scheme based on RSA
 * cryptography and described in Stimson p. 300 (with errors). The 512-
 * bit public modulus is n = p q, where p and q are secret large primes.
 * The TA rolls private random group key b as RSA exponent. These values
 * are known to all group members.
 *
 * When rolling new certificates, a server recomputes the private and
 * public keys. The private key u is a random roll, while the public key
 * is the inverse obscured by the group key v = (u^-1)^b. These values
 * replace the private and public keys normally generated by the RSA
 * scheme. Alice challenges Bob to confirm identity using the protocol
 * described below.
 *
 * How it works
 *
 * The scheme goes like this. Both Alice and Bob have the same modulus n
 * and some random b as the group key. These values are computed and
 * distributed in advance via secret means, although only the group key
 * b is truly secret. Each has a private random private key u and public
 * key (u^-1)^b, although not necessarily the same ones. Bob and Alice
 * can regenerate the key pair from time to time without affecting
 * operations. The public key is conveyed on the certificate in an
 * extension field; the private key is never revealed.
 *
 * Alice rolls new random challenge r and sends to Bob in the GQ
 * request message. Bob rolls new random k, then computes y = k u^r mod
 * n and x = k^b mod n and sends (y, hash(x)) to Alice in the response
 * message. Besides making the response shorter, the hash makes it
 * effectivey impossible for an intruder to solve for b by observing
 * a number of these messages.
 * 
 * Alice receives the response and computes y^b v^r mod n. After a bit
 * of algebra, this simplifies to k^b. If the hash of this result
 * matches hash(x), Alice knows that Bob has the group key b. The signed
 * response binds this knowledge to Bob's private key and the public key
 * previously received in his certificate.

 * The following routines implement the Mu-Varadharajan (MV) identity  *
 * scheme                                                              *
 *								       *
 ***********************************************************************
 *
 * The Mu-Varadharajan (MV) cryptosystem was originally intended when
 * servers broadcast messages to clients, but clients never send
 * messages to servers. There is one encryption key for the server and a
 * separate decryption key for each client. It operated something like a
 * pay-per-view satellite broadcasting system where the session key is
 * encrypted by the broadcaster and the decryption keys are held in a
 * tamperproof set-top box.
 *
 * The MV parameters and private encryption key hide in a DSA cuckoo
 * structure which uses the same parameters, but generated in a
 * different way. The values are used in an encryption scheme similar to
 * El Gamal cryptography and a polynomial formed from the expansion of
 * product terms (x - x[j]), as described in Mu, Y., and V.
 * Varadharajan: Robust and Secure Broadcasting, Proc. Indocrypt 2001,
 * 223-231. The paper has significant errors and serious omissions.
 *
 * Let q be the product of n distinct primes s1[j] (j = 1...n), where
 * each s1[j] has m significant bits. Let p be a prime p = 2 * q + 1, so
 * that q and each s1[j] divide p - 1 and p has M = n * m + 1
 * significant bits. Let g be a generator of Zp; that is, gcd(g, p - 1)
 * = 1 and g^q = 1 mod p. We do modular arithmetic over Zq and then
 * project into Zp* as exponents of g. Sometimes we have to compute an
 * inverse b^-1 of random b in Zq, but for that purpose we require
 * gcd(b, q) = 1. We expect M to be in the 500-bit range and n
 * relatively small, like 30. These are the parameters of the scheme and
 * they are expensive to compute.
 *
 * We set up an instance of the scheme as follows. A set of random
 * values x[j] mod q (j = 1...n), are generated as the zeros of a
 * polynomial of order n. The product terms (x - x[j]) are expanded to
 * form coefficients a[i] mod q (i = 0...n) in powers of x. These are
 * used as exponents of the generator g mod p to generate the private
 * encryption key A. The pair (gbar, ghat) of public server keys and the
 * pairs (xbar[j], xhat[j]) (j = 1...n) of private client keys are used
 * to construct the decryption keys. The devil is in the details.
 *
 * This routine generates a private server encryption file including the
 * private encryption key E and partial decryption keys gbar and ghat.
 * It then generates public client decryption files including the public
 * keys xbar[j] and xhat[j] for each client j. The partial decryption
 * files are used to compute the inverse of E. These values are suitably
 * blinded so secrets are not revealed.
 *
 * The distinguishing characteristic of this scheme is the capability to
 * revoke keys. Included in the calculation of E, gbar and ghat is the
 * product s = prod(s1[j]) (j = 1...n) above. If the factor s1[j] is
 * subsequently removed from the product and E, gbar and ghat
 * recomputed, the jth client will no longer be able to compute E^-1 and
 * thus unable to decrypt the messageblock.
 *
 * How it works
 *
 * The scheme goes like this. Bob has the server values (p, E, q, gbar,
 * ghat) and Alice has the client values (p, xbar, xhat).
 *
 * Alice rolls new random nonce r mod p and sends to Bob in the MV
 * request message. Bob rolls random nonce k mod q, encrypts y = r E^k
 * mod p and sends (y, gbar^k, ghat^k) to Alice.
 * 
 * Alice receives the response and computes the inverse (E^k)^-1 from
 * the partial decryption keys gbar^k, ghat^k, xbar and xhat. She then
 * decrypts y and verifies it matches the original r. The signed
 * response binds this knowledge to Bob's private key and the public key
 * previously received in his certificate.

.TP
.BR \-< " \fIrcfile\fP," " \--load-opts" "=\fIrcfile\fP," " \--no-load-opts"
Load options from \fIrcfile\fP.
The \fIno-load-opts\fP form will disable the loading
of earlier RC/INI files.  \fI--no-load-opts\fP is handled early,
out of order.
.TP
.BR \- " [{\fIv|c|n\fP}]," " \--version" "[=\fI{v|c|n}\fP]"
Output version of program and exit.  The default mode is `v', a simple
version.  The `c' mode will print copyright information and `n' will
print the full copyright notice.
.SH OPTION PRESETS
Any option that is not marked as \fInot presettable\fP may be preset
by loading values from configuration ("RC" or ".INI") file(s) and values from
environment variables named:
.nf
  \fBNTP_KEYGEN_\fP or \fBNTP_KEYGEN\fP
.fi
.ad
The environmental presets take precedence (are processed later than)
the configuration files.
The \fIhomerc\fP files are "\fI$HOME\fP", and "\fI.\fP".
If any of these are directories, then the file \fI.ntprc\fP
is searched for within those directories.

/*
 * timetrim.c
 * 
 * "timetrim" allows setting and adjustment of the system clock frequency
 * trim parameter on Silicon Graphics machines.  The trim value native
 * units are nanoseconds per second (10**-9), so a trim value of 1 makes
 * the system clock step ahead 1 nanosecond more per second than a value
 * of zero.  Xntpd currently uses units of 2**-20 secs for its frequency
 * offset (drift) values; to convert to a timetrim value, multiply by
 * 1E9 / 2**20 (about 954).
 * 
 * "timetrim" with no arguments just prints out the current kernel value.
 * With a numeric argument, the kernel value is set to the supplied value.
 * The "-i" flag causes the supplied value to be added to the kernel value.
 * The "-n" option causes all input and output to be in xntpd units rather
 * than timetrim native units.
 *
 * Note that there is a limit of +-3000000 (0.3%) on the timetrim value
 * which is (silently?) enforced by the kernel.
 *

#
# depsver.mf	included in Makefile.am for directories with .deps
#
# When building in the same directory with sources that change over
# time, such as when tracking using bk, the .deps files can become
# stale with respect to moved, deleted, or superceded headers.  Most
# commonly, this would exhibit as make reporting a failure to make a
# header file which is no longer in the location given.  To address
# this issue, we use a deps-ver file which is updated with each change
# that breaks old .deps files.  A copy of deps-ver is made into
# $(DEPDIR) if not already present.  If $(DEPDIR)/deps-ver is present
# with different contents than deps-ver, we make clean to ensure all
# .o files built before the incompatible change are rebuilt along with
# their updated .deps files, then remove $(DEPDIR) and recreate it as
# empty stubs.
#
# It is normal when configured with --disable-dependency-tracking for
# the DEPDIR to not have been created.  For this reason, we use the
# intermediate target .deps-ver, which invokes make recursively if
# DEPDIR exists.
#
# If you modify depsver.mf, please make the changes to the master
# copy, the one in sntp is copied by the bootstrap script from it.
#
# This comment block follows rather than leads the related code so that
# it stays with it in the generated Makefile.in and Makefile.
#

# Tell versions [3.59,3.63) of GNU make to not export all variables.
# Otherwise a system limit (for SysV at least) may be exceeded.

This directory contains the sources for the various utility programs.
See the README and RELNOTES files in the parent directory for directions
on how to make and install these programs.

The ntptime.c program checks the kernel configuration for the NTP user
interface syscalls ntp_gettime() and ntp_adjtime().  If present, the
current timekeeping data are displayed.  If not, a dissapointment is
displayed.  See the kernel page file in the HTML documentation in
distribution for further details. ntptime will be built be if configure
believes your system can use it.

The jitter.c program can be used to determine the timing jitter due to
the operating system in a gettimeofday() call.  For most systems the
dominant contribution to the jitter budget is the period of the hardware
interrupt, usually in the range 10 us-1 ms.  For those systems with
microsecond counters, such as recent Sun and certain HP and DEC systems,
the jitter is dominated only by the operating system.

The timetrim.c program can be used with SGI machines to implement a
scheme to discipline the hardware clock frequency.  See the source code
for further information.

The byteorder.c and longsize.c programs are used during the configuration
process to determine the byte order (little or big endian) and longword
size (32 or 64 bits).  See the configure scripts for further details.

The testrs6000.c program is used for testing purposes with the IBM
RS/6000 AIX machines. Bill Jones  reports:
"I could not get a tickadj of less than 40 us to work on a RS6000.
If you set it less than 40 us do so at your own risk!"

The tickadj.c program can be used to read and set various kernel
parameters affecting NTP operations. See the tickadj page in the HTML
documentation for further details.  tickadj will be built if configure
believes your system can use it.

 * tg.c generate WWV or IRIG signals for test
 */
/*
 * This program can generate audio signals that simulate the WWV/H
 * broadcast timecode. Alternatively, it can generate the IRIG-B
 * timecode commonly used to synchronize laboratory equipment. It is
 * intended to test the WWV/H driver (refclock_wwv.c) and the IRIG
 * driver (refclock_irig.c) in the NTP driver collection.
 *
 * Besides testing the drivers themselves, this program can be used to
 * synchronize remote machines over audio transmission lines or program
 * feeds. The program reads the time on the local machine and sets the
 * initial epoch of the signal generator within one millisecond.
 * Alernatively, the initial epoch can be set to an arbitrary time. This
 * is useful when searching for bugs and testing for correct response to
 * a leap second in UTC. Note however, the ultimate accuracy is limited
 * by the intrinsic frequency error of the codec sample clock, which can
 # reach well over 100 PPM.
 *
 * The default is to route generated signals to the line output
 * jack; the s option on the command line routes these signals to the
 * internal speaker as well. The v option controls the speaker volume
 * over the range 0-255. The signal generator by default uses WWV
 * format; the h option switches to WWVH format and the i option
 * switches to IRIG-B format.
 *
 * Once started the program runs continuously. The default initial epoch
 * for the signal generator is read from the computer system clock when
 * the program starts. The y option specifies an alternate epoch using a
 * string yydddhhmmss, where yy is the year of century, ddd the day of
 * year, hh the hour of day and mm the minute of hour. For instance,
 * 1946Z on 1 January 2006 is 060011946. The l option lights the leap
 * warning bit in the WWV/H timecode, so is handy to check for correct
 * behavior at the next leap second epoch. The remaining options are
 * specified below under the Parse Options heading. Most of these are
 * for testing.
 *
 * During operation the program displays the WWV/H timecode (9 digits)
 * or IRIG timecode (20 digits) as each new string is constructed. The
 * display is followed by the BCD binary bits as transmitted. Note that
 * the transmissionorder is low-order first as the frame is processed
 * left to right. For WWV/H The leap warning L preceeds the first bit.
 * For IRIG the on-time marker M preceeds the first (units) bit, so its
 * code is delayed one bit and the next digit (tens) needs only three
 * bits.
 *
 * The program has been tested with the Sun Blade 1500 running Solaris
 * 10, but not yet with other machines. It uses no special features and
 * should be readily portable to other hardware and operating systems.

/* Find the resolution of the system clock by watching how the current time

 * struct timeval is only good to 1us, which may cause problems as machines
 * get faster, but until then the logic goes:
 *
 * If a machine has resolution (i.e. accurate timing info) > 1us, then it will
 * probably use the "unused" low order bits as a counter (to force time to be
 * a strictly increaing variable), incrementing it each time any process
 * requests the time [[ or maybe time will stand still ? ]].
 *
 * SO: the logic goes:
 *
 *      IF      the difference from the last time is "small" (< MINSTEP)
 *      THEN    this machine is "counting" with the low order bits
 *      ELIF    this is not the first time round the loop
 *      THEN    this machine *WAS* counting, and has now stepped
 *      ELSE    this machine has resolution < time to read clock
 *
 * SO: if it exits on the first loop, assume "full accuracy" (1us)
 *     otherwise, take the log2(observered difference, rounded UP)
 *
 * MINLOOPS > 1 ensures that even if there is a STEP between the initial call
 * and the first loop, it doesn't stop too early.
 * Making it even greater allows MINSTEP to be reduced, assuming that the
 * chance of MINSTEP-1 other processes getting in and calling gettimeofday
 * between this processes's calls.
 * Reducing MINSTEP may be necessary as this sets an upper bound for the time
 * to actually call gettimeofday.

 * either decimal degrees or degrees:minutes:seconds.  Thus to compute
 * the delay between the WWVH (21:59:26N, 159:46:00W) and WWV (40:40:49N,
 * 105:02:27W) you could use:
 *
 * propdelay n21:59:26 w159:46 n40:40:49 w105:02:27
 *
 * By default it prints out a summer (F2 average virtual height 350 km) and
 * winter (F2 average virtual height 250 km) number.  The results will be
 * quite approximate but are about as good as you can do with HF time anyway.
 * You might pick a number between the values to use, or use the summer
 * value in the summer and switch to the winter value when the static
 * above 10 MHz starts to drop off in the fall.  You can also use the
 * -h switch if you want to specify your own virtual height.
 *
 * You can also do a
 *
 * propdelay -W n45:17:47 w75:45:22
 *
 * to find the propagation delays to WWV and WWVH (from CHU in this
 * case), a
 *
 * propdelay -C n40:40:49 w105:02:27
 *
 * to find the delays to CHU, and a
 *
 * propdelay -G n52:03:17 w98:34:18
 *
 * to find delays to GOES via each of the three satellites.

#
# depsver.mf	included in Makefile.am for directories with .deps
#
# When building in the same directory with sources that change over
# time, such as when tracking using bk, the .deps files can become
# stale with respect to moved, deleted, or superceded headers.  Most
# commonly, this would exhibit as make reporting a failure to make a
# header file which is no longer in the location given.  To address
# this issue, we use a deps-ver file which is updated with each change
# that breaks old .deps files.  A copy of deps-ver is made into
# $(DEPDIR) if not already present.  If $(DEPDIR)/deps-ver is present
# with different contents than deps-ver, we make clean to ensure all
# .o files built before the incompatible change are rebuilt along with
# their updated .deps files, then remove $(DEPDIR) and recreate it as
# empty stubs.
#
# It is normal when configured with --disable-dependency-tracking for
# the DEPDIR to not have been created.  For this reason, we use the
# intermediate target .deps-ver, which invokes make recursively if
# DEPDIR exists.
#
# If you modify depsver.mf, please make the changes to the master
# copy, the one in sntp is copied by the bootstrap script from it.
#
# This comment block follows rather than leads the related code so that
# it stays with it in the generated Makefile.in and Makefile.
#

# Tell versions [3.59,3.63) of GNU make to not export all variables.
# Otherwise a system limit (for SysV at least) may be exceeded.

This directory contains the sources for utility programs designed to
support radio clocks. The chutest.c and clktest.c are desgined to
test the chu_clk and tty_clk line disciplines and STREAMS modules in
the ../kernel directory.

These files have been modified to work with either the line disciplines
or the STREAMS modules. Be sure to define -DSTREAM if appropriate.

These are random bits of things written to help with clocks.  You can
make things in here by typing one or more of:

	make propdelay (or `make')
	make chutest
	make clktest

Propdelay computes high frequency propagation delays, given the
longitude and latitude of the transmitter and receiver.  Use
this for WWV/H and CHU.  Don't use it for WWVB (the computation
is easier for that).

Chutest can be used to input and process data from a CHU modem
attached to a serial port.  It will use the CHU line discipline
(if installed), or raw mode otherwise.  This was used to test
out the initial reduction algorithms, and may not be up to date.

Clktest can be used to test the clock line discipline (CLKLDISC,
it must be available), and to take a look at radio clocks attached to a
serial port.

treated as uninstalled libtool libraries, other files are standard or library
object files.

If the OUTPUT-FILE ends in \`.la', then a libtool library is created,
only library objects (\`.lo' files) may be specified, and \`-rpath' is
required, except when creating a convenience library.

If OUTPUT-FILE ends in \`.a' or \`.lib', then a standard library is created

# The TAGs below are defined such that we never get into a situation

# choices, we go for a static library, that is the most portable,
# since we can't tell whether shared libraries were disabled because
# the user asked for that or because the platform doesn't support
# them.  This is particularly important on AIX, because we don't
# support having both static and shared libraries enabled at the same
# time on that platform, so we default to a shared-only configuration.
# If a disable-shared tag is given, we'll fallback to a static-only
# configuration.  But we'll never go from static-only to shared-only.

#
# depsver.mf	included in Makefile.am for directories with .deps
#
# When building in the same directory with sources that change over
# time, such as when tracking using bk, the .deps files can become
# stale with respect to moved, deleted, or superceded headers.  Most
# commonly, this would exhibit as make reporting a failure to make a
# header file which is no longer in the location given.  To address
# this issue, we use a deps-ver file which is updated with each change
# that breaks old .deps files.  A copy of deps-ver is made into
# $(DEPDIR) if not already present.  If $(DEPDIR)/deps-ver is present
# with different contents than deps-ver, we make clean to ensure all
# .o files built before the incompatible change are rebuilt along with
# their updated .deps files, then remove $(DEPDIR) and recreate it as
# empty stubs.
#
# It is normal when configured with --disable-dependency-tracking for
# the DEPDIR to not have been created.  For this reason, we use the
# intermediate target .deps-ver, which invokes make recursively if
# DEPDIR exists.
#
# If you modify depsver.mf, please make the changes to the master
# copy, the one in sntp is copied by the bootstrap script from it.
#
# This comment block follows rather than leads the related code so that
# it stays with it in the generated Makefile.in and Makefile.
#

# Tell versions [3.59,3.63) of GNU make to not export all variables.
# Otherwise a system limit (for SysV at least) may be exceeded.

 * ntptimeset - get/set the time via ntp
 *
 * GOAL:
 * The goal of ntptime is to set the current time on system startup
 * to the best possible time using the network very wisely. It is assumed
 * that after a resonable time has been sett then ntp daemon will
 * maintain it.
 *
 * PROBLEM DOMAIN:
 * We have three sets of issues related to acheiving the goal. The first
 * issue is using the network when normal traffic is happening or when
 * the entire network world is recovering from a campus wide power failure
 * and is restarting. The second issue is the class of machine whether it
 * is a user's office workstation being handled by an uneducated user or
 * a server computer being handled by a trained operations staff. The third
 * issue is whether the ratio of people to computers and whether the 
 * environment is stable and viable or not.
 *
 * NETWORK USAGE:
 * The first issue of using the network wisely is a question of whether
 * the network load and time server load and state are normal. If things
 * are normal ntptime can do what ntpdate does of sending out 4 packets
 * quickly to each server (new transmit done with each ack). However
 * if network or time load is high then this scheme will simply contribute
 * to problems. Given we have minimal state, we simply weight lost packets
 * significantly and make sure we throttle output as much as possible
 * without performance lost for quick startups.
 *
 * TRAINING AND KNOWLEDGE:
 * The second issue of uneducated user of a office workstation versus a
 * trained operation staff of a server machine translates into simply an
 * issue of untrained and trained users.
 * 
 * The training issue implies that for the sake of the users involved in the
 * handling of their office workstation, problems and options should be
 * communicated simply and effectively and not in terse expert related
 * descriptions without possible options to be taken. The operator's training
 * and education enables them to deal with either type of communication and
 * control.
 *
 * AUTOMATION AND MANUAL CONTROL:
 * The last issue boils down to a design problem. If the design tends to go
 * into a manual mode when the environment is non-viable then one person
 * handling many computers all at the same time will be heavily impacted. On
 * the other hand, if the design tends to be automatic and does not indicate
 * a way for the user to take over control then the computer will be
 * unavailable for the user until the proble is resolved by someone else or
 * the user.
 *
 * NOTE: Please do not have this program print out every minute some line,
 *       of output. If this happens and the environment is in trouble then
 *       many pages of paper on many different machines will be filled up.
 *       Save some tress in your lifetime.
 * 
 * CONCLUSION:
 * The behavior of the program derived from these three issues should be
 * that during normal situations it quickly sets the time and allow the
 * system to startup.
 *
 * However during abnormal conditions as detected by unresponsive servers,
 * out-of-sync or bad responses and other detections, it should print out
 * a simple but clear message and continue in a mellow way to get the best
 * possible time. It may never get the time and if so should also indicate
 * this.

 ****************************************************************
 *
 * Much of the above is confusing or no longer relevant.  For example,
 * it is rare these days for a machine's console to be a printing terminal,
 * so the comment about saving trees doesn't mean much.  Nonetheless,
 * the basic principles still stand:
 *
 * - Work automatically, without human control or intervention.  To
 *   this end, we use the same configuration file as ntpd itself, so
 *   you don't have to specify servers or other information on the
 *   command line.  We also recognize that sometimes we won't be able
 *   to contact any servers, and give up in that event instead of
 *   hanging forever.
 *
 * - Behave in a sane way, both internally and externally, even in the
 *   face of insane conditions.  That means we back off quickly when
 *   we don't hear a response, to avoid network congestion.  Like
 *   ntpd, we verify responses from several servers before accepting
 *   the new time data.
 *
 *   However, we don't assume that the local clock is right, or even
 *   close, because it might not be at boot time, and we want to catch
 *   and correct that situation.  This behaviour has saved us in several
 *   instances.  On HP-UX 9.0x, there used to be a bug in adjtimed which
 *   would cause the time to be set to some wild value, making the machine
 *   essentially unusable (we use Kerberos authentication pervasively,
 *   and it requires workstations and servers to have a time within five
 *   minutes of the Kerberos server).  We also have problems on PC's
 *   running both Linux and some Microsoft OS -- they tend to disagree
 *   on what the BIOS clock should say, and who should update it, and
 *   when.  On those systems, we not only run ntptimeset at boot, we
 *   also reset the BIOS clock based on the result, so the correct
 *   time will be retained across reboots.
 *
 * For these reasons, and others, we have continued to use this tool
 * rather than ntpdate.  It is run automatically at boot time on every
 * workstation and server in our facility.
 *
 * In the past, we called this program 'ntptime'.  Unfortunately, the
 * ntp v4 distribution also includes a program with that name.  In
 * order to avoid confusion, we have renamed our program 'ntptimeset',
 * which more accurately describes what it does.

AT&T Freeware Year 2000 Certification
====================================

This is the "readme" file for the freeware application which has 
been certified by AT&T Labs as part of the "Freeware Y2K 
Certification Project".

DISCLAIMER
----------
    For its own internal business purposes AT&T Labs has
    assessed various programs obtained from the Internet for
    Year-2000 (Y2K) readiness that were not sufficiently certified
    for AT&T's needs.  As a service to the computing community
    AT&T Labs is freely releasing this information to the
    public as a series of "Y2K Application Updates", one update
    for what AT&T Labs considers an "application".

    For use outside of AT&T, AT&T Labs is not certifying this
    information is correct, that any software, including repairs
    and tests, will help others in any way, survive the year
    2000, nor work with current applications. Nor is AT&T
    taking any responsibility for repairing any Y2K problems
    that were overlooked nor repairing any bugs in any
    "Y2K Application Update". All risk of using this Y2K
    Application Update remains with the user who is expected
    to test that this update meets their needs.

    LICENSE TO USE
    AT&T's intent is to ensure these Y2K patches are freely
    available to the public but will not maintain a public web site
    for their distribution. Any copyright claims only only apply to 
    the specific changes made by Y2K to the code. Any original 
    copyright holders retain rights to unchanged code. Wherever 
    possible patches will be returned to the current owner(s) of the code.

    Owners and publishers are free to incorporate appropriate patches,
    upgrades, and tests within legal future distributions as long as
    they include the credit:

      Various Y2K updates and tests provided by AT&T Labs.
      Copyright 1999 AT&T.

    and any AT&T "comments" on the changed code remain intact.

    Any distributions of the updates must keep the entire update
    intact, without any change, including copyright and disclaimer
    information.  If integrated with the original application items
    not needed for an integrated release may be omitted. When
    distributed on the same media as the original application there
    must be no charge for this "Y2k Application Update".

    CONTACTS
    If you find any overlooked Y2K problems, or have other strictly Y2K
    repairs for the software, please E-mail:

            y2k@y2k.labs.att.com

    This address is strictly reserved for the topic at hand.
    AT&T makes no commitments to answer any E-mail
    to this address.  AT&T is free to use any submissions,
    including publishing in future Y2K related release notes,
    without payment or advance notice to the submitting person or
    persons... appropriate credit will be given in any future
    publications to the first person submitting something that
    AT&T uses.


======================================================================

Perl  ver - 4.036 
No. of Repairs: 2 Repairs
Compilation of Patches Required: No
OS Tested: Solaris 2.6

======================================================================

ORGANIZATION OF THE "Y2KFixes" DIRECTORY

The "Y2KFixes" directory has been included in the archive to give
you information about the Y2K testing that was conducted and their
results.

The Y2KFixes directory contains at least the following three files:
|----> NOTES.y2kfixes    -- Technical details about the Y2K Testing
|----> Readme.y2kfixes   -- this Readme file
|----> Results.y2kfixes  -- The results of Y2K Environment Tests

The directory may contain additional files and/or directories, as 
appropriate to the application, to provide the exact snapshots.


======================================================================

INSTALLING THE "PATCHES"

If you have downloaded a "patch", then you may install it as follows:

    At the same level as the source directory, invoke:

	patch -p < *.patches 

The patch file contains a header which has a manifest of changed files.

======================================================================

ADDITIONAL INSTRUCTIONS:


1) Extract the patches into perl-4.036 directory which is top level directory
   for the perl4 source.

2) cd to Y2KFixes.

3) It will have y2k directory which contains regression tests for Y2K testing.

4) now cd to ../t which contains TEST file for running this regression tests.

5) run TEST, see the results  & apply patches.

6) Once you apply the patch, you need to run a shell script in x2p/find2perl.SH
   which will generate find2perl.


======================================================================

Dave likes this code indented formatted in a consistent way.
The file "dot.emacs" has the emacs C-mode indentation style that Dave likes.

---

We'd like to see *all* system function declarations live in include/l_stdlib.h
and NEVER appear in the .c files.

# depsver.mf	included in Makefile.am for directories with .deps
#
# When building in the same directory with sources that change over
# time, such as when tracking using bk, the .deps files can become
# stale with respect to moved, deleted, or superceded headers.  Most
# commonly, this would exhibit as make reporting a failure to make a
# header file which is no longer in the location given.  To address
# this issue, we use a deps-ver file which is updated with each change
# that breaks old .deps files.  A copy of deps-ver is made into
# $(DEPDIR) if not already present.  If $(DEPDIR)/deps-ver is present
# with different contents than deps-ver, we make clean to ensure all
# .o files built before the incompatible change are rebuilt along with
# their updated .deps files, then remove $(DEPDIR) and recreate it as
# empty stubs.
#
# It is normal when configured with --disable-dependency-tracking for
# the DEPDIR to not have been created.  For this reason, we use the
# intermediate target .deps-ver, which invokes make recursively if
# DEPDIR exists.
#
# If you modify depsver.mf, please make the changes to the master
# copy, the one in sntp is copied by the bootstrap script from it.
#
# This comment block follows rather than leads the related code so that
# it stays with it in the generated Makefile.in and Makefile.
#

# Tell versions [3.59,3.63) of GNU make to not export all variables.
# Otherwise a system limit (for SysV at least) may be exceeded.

The adjtimed daemon emulates the BSD adjtime(2) system call.  The
adjtime() routine communicates with this daemon via SYSV messages.

The emulation uses an undocumented kernel variable (as of 6.0/2.0
and later releases) and as such it cannot be guaranteed to work in
future HP-UX releases.  Perhaps HP-UX will have a real adjtime(2)
system call in the future.

Author: Tai Jin (tai@sde.hp.com)
------------------------------------------------------------------------------

IMPORTANT NOTE: This stuff must be compiled with no optimization !!

NOTE: This code is known to work as of 8.0 on s300's, s700's and s800's.
      PLEASE do not modify it unless you have access to kernel sources
      and fully understand the implications of any changes you are making.
      One person already has trashed adjtimed by making it do "the right 
      thing".  This is not an exact replacement for BSD adjtime(2), don't
      try to make it into one.

==================

   These are generic *nix installation instructions.

   For Windows/NT, please see ports/winnt and html/build/hints/winnt.html.

   The `configure' shell script attempts to guess correct values for
various system-dependent variables used during compilation.  It uses
those values to create a `Makefile' in each directory of the package.
It may also create one or more `.h' files containing system-dependent
definitions.  Finally, it creates a shell script `config.status' that
you can run in the future to recreate the current configuration, a file
`config.cache' that saves the results of its tests to speed up
reconfiguring, and a file `config.log' containing compiler output
(useful mainly for debugging `configure').

   If you need to do unusual things to compile the package, please try
to figure out how `configure' could check whether to do them, and mail
diffs or instructions to the address given in the `README' so they can
be considered for the next release.  If at some point `config.cache'
contains results you don't want to keep, you may remove or edit it.

   The file `configure.in' is used to create `configure' by a program
called `autoconf'.  You only need `configure.in' if you want to change
it or regenerate `configure' using a newer version of `autoconf'.

The simplest way to compile this package is:

  1. `cd' to the directory containing the package's source code and type
     `./configure' to configure the package for your system.  If you're
     using `csh' on an old version of System V, you might need to type
     `sh ./configure' instead to prevent `csh' from trying to execute
     `configure' itself.

     Running `configure' takes a while.  While running, it prints some
     messages telling which features it is checking for.

  2. Type `make' to compile the package.

  3. Optionally, type `make check' to run any self-tests that come with
     the package.

  4. Type `make install' to install the programs and any data files and
     documentation.

  5. You can remove the program binaries and object files from the
     source code directory by typing `make clean'.  To also remove the
     files that `configure' created (so you can compile the package for
     a different kind of computer), type `make distclean'.  There is
     also a `make maintainer-clean' target, but that is intended mainly
     for the package's developers.  If you use it, you may have to get
     all sorts of other programs in order to regenerate files that came
     with the distribution.

Compilers and Options
=====================

   Some systems require unusual options for compilation or linking that
the `configure' script does not know about.  You can give `configure'
initial values for variables by setting them in the environment.  Using
a Bourne-compatible shell, you can do that on the command line like
this:
     CC=c89 CFLAGS=-O2 LIBS=-lposix ./configure

Or on systems that have the `env' program, you can do it like this:
     env CPPFLAGS=-I/usr/local/include LDFLAGS=-s ./configure

Compiling For Multiple Architectures
====================================

   You can compile the package for more than one kind of computer at the
same time, by placing the object files for each architecture in their
own directory.  To do this, you must use a version of `make' that
supports the `VPATH' variable, such as GNU `make'.  `cd' to the
directory where you want the object files and executables to go and run
the `configure' script.  `configure' automatically checks for the
source code in the directory that `configure' is in and in `..'.

   If you have to use a `make' that does not supports the `VPATH'
variable, you have to compile the package for one architecture at a time
in the source code directory.  After you have installed the package for
one architecture, use `make distclean' before reconfiguring for another
architecture.

Installation Names
==================

   By default, `make install' will install the package's files in
`/usr/local/bin', `/usr/local/man', etc.  You can specify an
installation prefix other than `/usr/local' by giving `configure' the
option `--prefix=PATH'.

   You can specify separate installation prefixes for
architecture-specific files and architecture-independent files.  If you
give `configure' the option `--exec-prefix=PATH', the package will use
PATH as the prefix for installing programs and libraries.
Documentation and other data files will still use the regular prefix.

   If the package supports it, you can cause programs to be installed
with an extra prefix or suffix on their names by giving `configure' the
option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'.

Optional Features
=================

   Some packages pay attention to `--enable-FEATURE' options to
`configure', where FEATURE indicates an optional part of the package.
They may also pay attention to `--with-PACKAGE' options, where PACKAGE
is something like `gnu-as' or `x' (for the X Window System).  The
`README' should mention any `--enable-' and `--with-' options that the
package recognizes.

   For packages that use the X Window System, `configure' can usually
find the X include and library files automatically, but if it doesn't,
you can use the `configure' options `--x-includes=DIR' and
`--x-libraries=DIR' to specify their locations.

Specifying the System Type
==========================

   There may be some features `configure' can not figure out
automatically, but needs to determine by the type of host the package
will run on.  Usually `configure' can figure that out, but if it prints
a message saying it can not guess the host type, give it the
`--host=TYPE' option.  TYPE can either be a short name for the system
type, such as `sun4', or a canonical name with three fields:
     CPU-COMPANY-SYSTEM

See the file `config.sub' for the possible values of each field.  If
`config.sub' isn't included in this package, then this package doesn't
need to know the host type.

   If you are building compiler tools for cross-compiling, you can also
use the `--target=TYPE' option to select the type of system they will
produce code for and the `--build=TYPE' option to select the type of
system on which you are compiling the package.

Sharing Defaults
================

   If you want to set default values for `configure' scripts to share,
you can create a site shell script called `config.site' that gives
default values for variables like `CC', `cache_file', and `prefix'.
`configure' looks for `PREFIX/share/config.site' if it exists, then
`PREFIX/etc/config.site' if it exists.  Or, you can set the
`CONFIG_SITE' environment variable to the location of the site script.
A warning: not all `configure' scripts look for a site script.

Operation Controls
==================

   `configure' recognizes the following options to control how it
operates.

`--cache-file=FILE'
     Use and save the results of the tests in FILE instead of
     `./config.cache'.  Set FILE to `/dev/null' to disable caching, for
     debugging `configure'.

`--help'
     Print a summary of the options to `configure', and exit.

`--quiet'
`--silent'
`-q'
     Do not print messages saying which checks are being made.

`--srcdir=DIR'
     Look for the package's source code in directory DIR.  Usually
     `configure' can determine that directory automatically.

`--version'
     Print the version of Autoconf used to generate the `configure'
     script, and exit.

`configure' also accepts some other, not widely useful, options.

# For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
# $ac_aux_dir to `$srcdir/foo'.  In other projects, it is set to
# `$srcdir', `$srcdir/..', or `$srcdir/../..'.
#
# Of course, Automake must honor this variable whenever it calls a
# tool from the auxiliary directory.  The problem is that $srcdir (and
# therefore $ac_aux_dir as well) can be either absolute or relative,
# depending on how configure is run.  This is pretty annoying, since
# it makes $ac_aux_dir quite unusable in subdirectories: in the top
# source directory, any form will work fine, but in subdirectories a
# relative path needs to be adjusted first.
#
# $ac_aux_dir/missing
#    fails when called from a subdirectory if $ac_aux_dir is relative
# $top_srcdir/$ac_aux_dir/missing
#    fails if $ac_aux_dir is absolute,
#    fails when called from a subdirectory in a VPATH build with
#          a relative $ac_aux_dir
#
# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
# are both prefixed by $srcdir.  In an in-source build this is usually
# harmless because $srcdir is `.', but things will broke when you
# start a VPATH build or use an absolute $srcdir.
#
# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
# iff we strip the leading $srcdir from $ac_aux_dir.  That would be:
#   am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
# and then we would define $MISSING as
#   MISSING="\${SHELL} $am_aux_dir/missing"
# This will work as long as MISSING is not called from configure, because
# unfortunately $(top_srcdir) has no meaning in configure.
# However there are other variables, like CC, which are often used in
# configure, and could therefore not use this "fixed" $ac_aux_dir.
#
# Another solution, used here, is to always expand $ac_aux_dir to an
# absolute PATH.  The drawback is that using absolute paths prevent a
# configured tree to be moved without reconfiguration.

	The

	in Appendix B of the NTPv3 specification RFC1305, requesting
	information about current state and/or changes in that state.
	The same formats are used in NTPv4, although some of the
	variables have changed and new ones added.
	_END_DETAIL;

prog-man-descrip = <<-  _END_PROG_MAN_DESCRIP
	The
	[= prog-name =]
	utility program is used to query NTP servers which
	implement the standard NTP mode 6 control message formats defined
	in Appendix B of the NTPv3 specification RFC1305, requesting
	information about current state and/or changes in that state.
	The same formats are used in NTPv4, although some of the
	variables have changed and new ones added. The description on this
	page is for the NTPv4 variables.
	The program may be run either in interactive mode or controlled using
	command line arguments.
	Requests to read and write arbitrary
	variables can be assembled, with raw and pretty-printed output
	options being available.
	The
	[= prog-name =]
	utility can also obtain and print a
	list of peers in a common format by sending multiple queries to the
	server.

	If one or more request options is included on the command line
	when
	[= prog-name =]
	is executed, each of the requests will be sent
	to the NTP servers running on each of the hosts given as command
	line arguments, or on localhost by default.
	If no request options
	are given,
	[= prog-name =]
	will attempt to read commands from the
	standard input and execute these on the NTP server running on the
	first host given on the command line, again defaulting to localhost
	when no other host is specified.
	The
	[= prog-name =]
	utility will prompt for
	commands if the standard input is a terminal device.

	The
	[= prog-name =]
	utility uses NTP mode 6 packets to communicate with the
	NTP server, and hence can be used to query any compatible server on
	the network which permits it.
	Note that since NTP is a UDP protocol
	this communication will be somewhat unreliable, especially over
	large distances in terms of network topology.
	The
	[= prog-name =]
	utility makes
	one attempt to retransmit requests, and will time requests out if
	the remote host is not heard from within a suitable timeout
	time.

	Specifying a
	command line option other than
	.Fl i
	or
	.Fl n
	will
	cause the specified query (queries) to be sent to the indicated
	host(s) immediately.
	Otherwise,
	[= prog-name =]  
	will attempt to read
	interactive format commands from the standard input.
	.Ss "Internal Commands"
	Interactive format commands consist of a keyword followed by zero
	to four arguments.
	Only enough characters of the full keyword to
	uniquely identify the command need be typed.

	A
	number of interactive format commands are executed entirely within
	the
	[= prog-name =]
	utility itself and do not result in NTP mode 6
	requests being sent to a server.
	These are described following.
	@table @code
	@item ? [command_keyword]
	@itemx help [command_keyword]
	A
	.Ql \&?
	by itself will print a list of all the command
	keywords known to this incarnation of
	[= prog-name =] .
	A
	.Ql \&?
	followed by a command keyword will print function and usage
	information about the command.
	This command is probably a better
	source of information about
	[= prog-name =]
	than this manual
	page.
	@item addvars
	.Ar variable_name [=value] ...
	.Xc
	@item rmvars variable_name ...
	@item clearvars
	The data carried by NTP mode 6 messages consists of a list of
	items of the form
	.Ql variable_name=value ,
	where the
	.Ql =value
	is ignored, and can be omitted,
	in requests to the server to read variables.
	The
	[= prog-name =]
	utility maintains an internal list in which data to be included in control
	messages can be assembled, and sent using the
	.Ic readlist
	and
	.Ic writelist
	commands described below.
	The
	.Ic addvars
	command allows variables and their optional values to be added to
	the list.
	If more than one variable is to be added, the list should
	be comma-separated and not contain white space.
	The
	.Ic rmvars
	command can be used to remove individual variables from the list,
	while the
	.Ic clearlist
	command removes all variables from the
	list.
	@item authenticate [ yes | no ]
	Normally
	[= prog-name =]
	does not authenticate requests unless
	they are write requests.
	The command
	.Ql authenticate yes
	causes
	[= prog-name =]
	to send authentication with all requests it
	makes.
	Authenticated requests causes some servers to handle
	requests slightly differently, and can occasionally melt the CPU in
	fuzzballs if you turn authentication on before doing a
	.Ic peer
	display.
	The command
	.Ql authenticate
	causes
	[= prog-name =]
	to display whether or not
	[= prog-name =]
	is currently autheinticating requests.
	@item cooked
	Causes output from query commands to be "cooked", so that
	variables which are recognized by
	[= prog-name =]
	will have their
	values reformatted for human consumption.
	Variables which
	[= prog-name =]
	thinks should have a decodable value but didn't are
	marked with a trailing
	.Ql \&? .
	.@item debug [
	.Cm more |
	.Cm less |
	.Cm off
	]
	.Xc
	With no argument, displays the current debug level.
	Otherwise, the debug level is changed to the indicated level.
	@item delay milliseconds
	Specify a time interval to be added to timestamps included in
	requests which require authentication.
	This is used to enable
	(unreliable) server reconfiguration over long delay network paths
	or between machines whose clocks are unsynchronized.
	Actually the
	server does not now require timestamps in authenticated requests,
	so this command may be obsolete.
	@item host hostname
	Set the host to which future queries will be sent.
	Hostname may
	be either a host name or a numeric address.
	@item hostnames Cm yes | Cm no
	If
	.Cm yes
	is specified, host names are printed in
	information displays.
	If
	.Cm no
	is specified, numeric
	addresses are printed instead.
	The default is
	.Cm yes ,
	unless
	modified using the command line
	.Fl n
	switch.
	@item keyid keyid
	This command allows the specification of a key number to be
	used to authenticate configuration requests.
	This must correspond
	to a key number the server has been configured to use for this
	purpose.
	@item ntpversion [
	.Cm 1 |
	.Cm 2 |
	.Cm 3 |
	.Cm 4
	]
	.Xc
	Sets the NTP version number which
	[= prog-name =]
	claims in
	packets.
	Defaults to 3, Note that mode 6 control messages (and
	modes, for that matter) didn't exist in NTP version 1.
	There appear
	to be no servers left which demand version 1.
	With no argument, displays the current NTP version that will be used
	when communicating with servers.
	@item quit
	Exit
	[= prog-name =] .
	@item passwd
	This command prompts you to type in a password (which will not
	be echoed) which will be used to authenticate configuration
	requests.
	The password must correspond to the key configured for
	use by the NTP server for this purpose if such requests are to be
	successful.
	@item raw
	Causes all output from query commands is printed as received
	from the remote server.
	The only formating/interpretation done on
	the data is to transform nonascii data into a printable (but barely
	understandable) form.
	@item timeout Ar milliseconds
	Specify a timeout period for responses to server queries.
	The
	default is about 5000 milliseconds.
	Note that since
	[= prog-name =]
	retries each query once after a timeout, the total waiting time for
	a timeout will be twice the timeout value set.
	@end table

This program has no explanation.

The
[= prog-name =]
utility program is used to query NTP servers which
implement the standard NTP mode 6 control message formats defined
in Appendix B of the NTPv3 specification RFC1305, requesting
information about current state and/or changes in that state.
The same formats are used in NTPv4, although some of the
variables have changed and new ones added.

This section was generated by @strong{AutoGen},
the aginfo template and the option descriptions for the @command{ntpq} program.  It documents the @command{ntpq} usage text and option meanings.

                                - may appear multiple times

Options are specified by doubled hyphens and their name or by a single
hyphen and the flag character.

The following option preset mechanisms are supported:
 - reading file $HOME/.ntprc
 - reading file ./.ntprc
 - examining environment variables named NTPQ_*

The [= prog-name =] utility program is used to query NTP servers which
implement the standard NTP mode 6 control message formats defined in
Appendix B of the NTPv3 specification RFC1305, requesting information
about current state and/or changes in that state.  The same formats are
used in NTPv4, although some of the variables have changed and new ones
added.

@node ntpq command
@subsection command option (-c)
@cindex ntpq-command

This is the ``run a command and exit'' option.

This option has some usage constraints.  It:
@itemize @bullet
@item
may appear an unlimited number of times.
@end itemize

The following argument is interpreted as an interactive format command
and is added to the list of commands to be executed on the specified
host(s).

@node ntpq debug-level
@subsection debug-level option (-d)
@cindex ntpq-debug-level

This is the ``increase output debug message level'' option.

This option has some usage constraints.  It:
@itemize @bullet
@item
may appear an unlimited number of times.
@end itemize

Increase the debugging message output level.

@node ntpq interactive
@subsection interactive option (-i)
@cindex ntpq-interactive

This is the ``force ntpq to operate in interactive mode'' option.

This option has some usage constraints.  It:
@itemize @bullet
@item
must not appear in combination with any of the following options:
command, peers.
@end itemize

Force ntpq to operate in interactive mode.  Prompts will be written
to the standard output and commands read from the standard input.

@node ntpq ipv4
@subsection ipv4 option (-4)
@cindex ntpq-ipv4

This is the ``force ipv4 dns name resolution'' option.

This option has some usage constraints.  It:
@itemize @bullet
@item
must not appear in combination with any of the following options:
ipv6.
@end itemize

Force DNS resolution of following host names on the command line
to the IPv4 namespace.

@node ntpq ipv6
@subsection ipv6 option (-6)
@cindex ntpq-ipv6

This is the ``force ipv6 dns name resolution'' option.

This option has some usage constraints.  It:
@itemize @bullet
@item
must not appear in combination with any of the following options:
ipv4.
@end itemize

Force DNS resolution of following host names on the command line
to the IPv6 namespace.

@node ntpq numeric
@subsection numeric option (-n)
@cindex ntpq-numeric

This is the ``numeric host addresses'' option.
Output all host addresses in dotted-quad numeric format rather than
converting to the canonical host names. 

@node ntpq old-rv
@subsection old-rv option
@cindex ntpq-old-rv

This is the ``always output status line with readvar'' option.
By default, ntpq now suppresses the associd=... line that
precedes the output of "readvar" (alias "rv") when a single
variable is requested, such as ntpq -c "rv 0 offset".  This
option causes ntpq to include both lines of output for a
single-variable readvar.  Using an environment variable to
preset this option in a script will enable both older and
newer ntpq to behave identically in this regard.

@node ntpq peers
@subsection peers option (-p)
@cindex ntpq-peers

This is the ``print a list of the peers'' option.

This option has some usage constraints.  It:
@itemize @bullet
@item
must not appear in combination with any of the following options:
interactive.
@end itemize

Print a list of the peers known to the server as well as a summary
of their state. This is equivalent to the 'peers' interactive command.

@node ntpq set-debug-level
@subsection set-debug-level option (-D)
@cindex ntpq-set-debug-level

This is the ``set the output debug message level'' option.

This option has some usage constraints.  It:
@itemize @bullet
@item
may appear an unlimited number of times.
@end itemize

Set the output debugging level.  Can be supplied multiple times,
but each overrides the previous value(s).

#
# depsver.mf	included in Makefile.am for directories with .deps
#
# When building in the same directory with sources that change over
# time, such as when tracking using bk, the .deps files can become
# stale with respect to moved, deleted, or superceded headers.  Most
# commonly, this would exhibit as make reporting a failure to make a
# header file which is no longer in the location given.  To address
# this issue, we use a deps-ver file which is updated with each change
# that breaks old .deps files.  A copy of deps-ver is made into
# $(DEPDIR) if not already present.  If $(DEPDIR)/deps-ver is present
# with different contents than deps-ver, we make clean to ensure all
# .o files built before the incompatible change are rebuilt along with
# their updated .deps files, then remove $(DEPDIR) and recreate it as
# empty stubs.
#
# It is normal when configured with --disable-dependency-tracking for
# the DEPDIR to not have been created.  For this reason, we use the
# intermediate target .deps-ver, which invokes make recursively if
# DEPDIR exists.
#
# If you modify depsver.mf, please make the changes to the master
# copy, the one in sntp is copied by the bootstrap script from it.
#
# This comment block follows rather than leads the related code so that
# it stays with it in the generated Makefile.in and Makefile.
#

# Tell versions [3.59,3.63) of GNU make to not export all variables.
# Otherwise a system limit (for SysV at least) may be exceeded.

.SH "DESCRIPTION"
This manual page briefly documents the \fBntpq\fP command.
The
[= prog-name =]
utility program is used to query NTP servers which
implement the standard NTP mode 6 control message formats defined
in Appendix B of the NTPv3 specification RFC1305, requesting
information about current state and/or changes in that state.
The same formats are used in NTPv4, although some of the
variables have changed and new ones added. The description on this
page is for the NTPv4 variables.
The program may be run either in interactive mode or controlled using
command line arguments.
Requests to read and write arbitrary
variables can be assembled, with raw and pretty-printed output
options being available.
The
[= prog-name =]
utility can also obtain and print a
list of peers in a common format by sending multiple queries to the
server.

If one or more request options is included on the command line
when
[= prog-name =]
is executed, each of the requests will be sent
to the NTP servers running on each of the hosts given as command
line arguments, or on localhost by default.
If no request options
are given,
[= prog-name =]
will attempt to read commands from the
standard input and execute these on the NTP server running on the
first host given on the command line, again defaulting to localhost
when no other host is specified.
The
[= prog-name =]
utility will prompt for
commands if the standard input is a terminal device.

The
[= prog-name =]
utility uses NTP mode 6 packets to communicate with the
NTP server, and hence can be used to query any compatible server on
the network which permits it.
Note that since NTP is a UDP protocol
this communication will be somewhat unreliable, especially over
large distances in terms of network topology.
The
[= prog-name =]
utility makes
one attempt to retransmit requests, and will time requests out if
the remote host is not heard from within a suitable timeout
time.

Specifying a
command line option other than
.Fl i
or
.Fl n
will
cause the specified query (queries) to be sent to the indicated
host(s) immediately.
Otherwise,
[= prog-name =]  
will attempt to read
interactive format commands from the standard input.
.Ss "Internal Commands"
Interactive format commands consist of a keyword followed by zero
to four arguments.
Only enough characters of the full keyword to
uniquely identify the command need be typed.

A
number of interactive format commands are executed entirely within
the
[= prog-name =]
utility itself and do not result in NTP mode 6
requests being sent to a server.
These are described following.
.sp
.IR "? [command_keyword]"
.sp 1x help [command_keyword]
A
.Ql \&?
by itself will print a list of all the command
keywords known to this incarnation of
[= prog-name =] .
A
.Ql \&?
followed by a command keyword will print function and usage
information about the command.
This command is probably a better
source of information about
[= prog-name =]
than this manual
page.
.sp
.IR "addvars"
.Ar variable_name [=value] ...
.Xc
.sp
.IR "rmvars variable_name ..."
.sp
.IR "clearvars"
The data carried by NTP mode 6 messages consists of a list of
items of the form
.Ql variable_name=value ,
where the
.Ql =value
is ignored, and can be omitted,
in requests to the server to read variables.
The
[= prog-name =]
utility maintains an internal list in which data to be included in control
messages can be assembled, and sent using the
.Ic readlist
and
.Ic writelist
commands described below.
The
.Ic addvars
command allows variables and their optional values to be added to
the list.
If more than one variable is to be added, the list should
be comma-separated and not contain white space.
The
.Ic rmvars
command can be used to remove individual variables from the list,
while the
.Ic clearlist
command removes all variables from the
list.
.sp
.IR "authenticate [ yes | no ]"
Normally
[= prog-name =]
does not authenticate requests unless
they are write requests.
The command
.Ql authenticate yes
causes
[= prog-name =]
to send authentication with all requests it
makes.
Authenticated requests causes some servers to handle
requests slightly differently, and can occasionally melt the CPU in
fuzzballs if you turn authentication on before doing a
.Ic peer
display.
The command
.Ql authenticate
causes
[= prog-name =]
to display whether or not
[= prog-name =]
is currently autheinticating requests.
.sp
.IR "cooked"
Causes output from query commands to be "cooked", so that
variables which are recognized by
[= prog-name =]
will have their
values reformatted for human consumption.
Variables which
[= prog-name =]
thinks should have a decodable value but didn't are
marked with a trailing
.Ql \&? .
.@item debug [
.Cm more |
.Cm less |
.Cm off
]
.Xc
With no argument, displays the current debug level.
Otherwise, the debug level is changed to the indicated level.
.sp
.IR "delay milliseconds"
Specify a time interval to be added to timestamps included in
requests which require authentication.
This is used to enable
(unreliable) server reconfiguration over long delay network paths
or between machines whose clocks are unsynchronized.
Actually the
server does not now require timestamps in authenticated requests,
so this command may be obsolete.
.sp
.IR "host hostname"
Set the host to which future queries will be sent.
Hostname may
be either a host name or a numeric address.
.sp
.IR "hostnames Cm yes | Cm no"
If
.Cm yes
is specified, host names are printed in
information displays.
If
.Cm no
is specified, numeric
addresses are printed instead.
The default is
.Cm yes ,
unless
modified using the command line
.Fl n
switch.
.sp
.IR "keyid keyid"
This command allows the specification of a key number to be
used to authenticate configuration requests.
This must correspond
to a key number the server has been configured to use for this
purpose.
.sp
.IR "ntpversion ["
.Cm 1 |
.Cm 2 |
.Cm 3 |
.Cm 4
]
.Xc
Sets the NTP version number which
[= prog-name =]
claims in
packets.
Defaults to 3, Note that mode 6 control messages (and
modes, for that matter) didn't exist in NTP version 1.
There appear
to be no servers left which demand version 1.
With no argument, displays the current NTP version that will be used
when communicating with servers.
.sp
.IR "quit"
Exit
[= prog-name =] .
.sp
.IR "passwd"
This command prompts you to type in a password (which will not
be echoed) which will be used to authenticate configuration
requests.
The password must correspond to the key configured for
use by the NTP server for this purpose if such requests are to be
successful.
.sp
.IR "raw"
Causes all output from query commands is printed as received
from the remote server.
The only formating/interpretation done on
the data is to transform nonascii data into a printable (but barely
understandable) form.
.sp
.IR "timeout Ar milliseconds"
Specify a timeout period for responses to server queries.
The
default is about 5000 milliseconds.
Note that since
[= prog-name =]
retries each query once after a timeout, the total waiting time for
a timeout will be twice the timeout value set.

Force ntpq to operate in interactive mode.
This option must not appear in combination with any of the following options:
command, peers.
.sp
Force ntpq to operate in interactive mode.  Prompts will be written
to the standard output and commands read from the standard input.
.TP
.BR \-n ", " \--numeric
numeric host addresses.
.sp
Output all host addresses in dotted-quad numeric format rather than
converting to the canonical host names.

.sp
By default, ntpq now suppresses the associd=... line that
precedes the output of "readvar" (alias "rv") when a single
variable is requested, such as ntpq \-c "rv 0 offset".  This
option causes ntpq to include both lines of output for a
single-variable readvar.  Using an environment variable to
preset this option in a script will enable both older and
newer ntpq to behave identically in this regard.
.TP
.BR \-? , " \--help"
Display extended usage information and exit.
.TP
.BR \-! , " \--more-help"
Extended usage information passed thru pager.

of earlier RC/INI files.  \fI--no-load-opts\fP is handled early,
out of order.
.TP
.BR \- " [{\fIv|c|n\fP}]," " \--version" "[=\fI{v|c|n}\fP]"
Output version of program and exit.  The default mode is `v', a simple
version.  The `c' mode will print copyright information and `n' will
print the full copyright notice.
.SH OPTION PRESETS
Any option that is not marked as \fInot presettable\fP may be preset
by loading values from configuration ("RC" or ".INI") file(s) and values from
environment variables named:
.nf
  \fBNTPQ_\fP or \fBNTPQ\fP
.fi
.ad
The environmental presets take precedence (are processed later than)
the configuration files.
The \fIhomerc\fP files are "\fI$HOME\fP", and "\fI.\fP".
If any of these are directories, then the file \fI.ntprc\fP
is searched for within those directories.

This directory contains example run-time configuration files for the
NTP Version 4 daemon ntpd. These files illustrate some of the more
obtuse configurations you may run into. They are not likely to do
anything good if run on machines other than their native spot, so don't
just blindly copy something and put it up. Additional information can
be found in the ./doc directory of the base directory.

Included also are example public key and symmetric key files produced
by the ntp-genkeys program with names prefixed by ntpkey. These are
ordinarily kept in /usr/local/etc and used by the Autokey scheme. See
the authopt.htm pnd genkeys.htm ages for further information.

/*
 * sendrequest - format and send a request packet
 *
 * Historically, ntpdc has used a fixed-size request packet regardless
 * of the actual payload size.  When authenticating, the timestamp, key
 * ID, and digest have been placed just before the end of the packet.
 * With the introduction in late 2009 of support for authenticated
 * ntpdc requests using larger 20-octet digests (vs. 16 for MD5), we
 * come up four bytes short.
 *
 * To maintain interop while allowing for larger digests, the behavior
 * is unchanged when using 16-octet digests.  For larger digests, the
 * timestamp, key ID, and digest are placed immediately following the
 * request payload, with the overall packet size variable.  ntpd can
 * distinguish 16-octet digests by the overall request size being
 * REQ_LEN_NOMAC + 4 + 16 with the auth bit enabled.  When using a
 * longer digest, that request size should be avoided.
 *
 * With the form used with 20-octet and larger digests, the timestamp,
 * key ID, and digest are located by ntpd relative to the start of the
 * packet, and the size of the digest is then implied by the packet
 * size.

This program has no explanation.

The
[= prog-name =]
utility program is used to query an NTP daemon about its
current state and to request changes in that state.
It uses NTP mode 7 control message formats described in the source code.
The program may
be run either in interactive mode or controlled using command line
arguments.
Extensive state and statistics information is available
through the
[= prog-name =]
interface.
In addition, nearly all the
configuration options which can be specified at startup using
ntpd's configuration file may also be specified at run time using
[= prog-name =] .



This section was generated by @strong{AutoGen},
the aginfo template and the option descriptions for the @command{ntpdc} program.  It documents the @command{ntpdc} usage text and option meanings.

# depsver.mf	included in Makefile.am for directories with .deps
#
# When building in the same directory with sources that change over
# time, such as when tracking using bk, the .deps files can become
# stale with respect to moved, deleted, or superceded headers.  Most
# commonly, this would exhibit as make reporting a failure to make a
# header file which is no longer in the location given.  To address
# this issue, we use a deps-ver file which is updated with each change
# that breaks old .deps files.  A copy of deps-ver is made into
# $(DEPDIR) if not already present.  If $(DEPDIR)/deps-ver is present
# with different contents than deps-ver, we make clean to ensure all
# .o files built before the incompatible change are rebuilt along with
# their updated .deps files, then remove $(DEPDIR) and recreate it as
# empty stubs.
#
# It is normal when configured with --disable-dependency-tracking for
# the DEPDIR to not have been created.  For this reason, we use the
# intermediate target .deps-ver, which invokes make recursively if
# DEPDIR exists.
#
# If you modify depsver.mf, please make the changes to the master
# copy, the one in sntp is copied by the bootstrap script from it.
#
# This comment block follows rather than leads the related code so that

.SH "DESCRIPTION"
This manual page briefly documents the \fBntpdc\fP command.
The
[= prog-name =]
utility program is used to query an NTP daemon about its
current state and to request changes in that state.
It uses NTP mode 7 control message formats described in the source code.
The program may
be run either in interactive mode or controlled using command line
arguments.
Extensive state and statistics information is available
through the
[= prog-name =]
interface.
In addition, nearly all the
configuration options which can be specified at startup using
ntpd's configuration file may also be specified at run time using
[= prog-name =] .

.SH OPTION PRESETS
Any option that is not marked as \fInot presettable\fP may be preset
by loading values from configuration ("RC" or ".INI") file(s) and values from
environment variables named:
.nf
  \fBNTPDC_\fP or \fBNTPDC\fP
.fi
.ad
The environmental presets take precedence (are processed later than)
the configuration files.
The \fIhomerc\fP files are "\fI$HOME\fP", and "\fI.\fP".
If any of these are directories, then the file \fI.ntprc\fP
is searched for within those directories.

/*
 * random.c:
 *
 * An improved random number generation package.  In addition to the standard
 * rand()/srand() like interface, this package also has a special state info
 * interface.  The initstate() routine is called with a seed, an array of
 * bytes, and a count of how many bytes are being passed in; this array is
 * then initialized to contain information for random number generation with
 * that much state information.  Good sizes for the amount of state
 * information are 32, 64, 128, and 256 bytes.  The state can be switched by
 * calling the setstate() routine with the same array as was initiallized
 * with initstate().  By default, the package runs with 128 bytes of state
 * information and generates far better random numbers than a linear
 * congruential generator.  If the amount of state information is less than
 * 32 bytes, a simple linear congruential R.N.G. is used.
 *
 * Internally, the state information is treated as an array of longs; the
 * zeroeth element of the array is the type of R.N.G. being used (small
 * integer); the remainder of the array is the state information for the
 * R.N.G.  Thus, 32 bytes of state information will give 7 longs worth of
 * state information, which will allow a degree seven polynomial.  (Note:
 * the zeroeth word of state information also has some other information
 * stored in it -- see setstate() for details).
 *
 * The random number generation technique is a linear feedback shift register
 * approach, employing trinomials (since there are fewer terms to sum up that
 * way).  In this approach, the least significant bit of all the numbers in
 * the state table will act as a linear feedback shift register, and will
 * have period 2^deg - 1 (where deg is the degree of the polynomial being
 * used, assuming that the polynomial is irreducible and primitive).  The
 * higher order bits will have longer periods, since their values are also
 * influenced by pseudo-random carries out of the lower bits.  The total
 * period of the generator is approximately deg*(2**deg - 1); thus doubling
 * the amount of state information has a vast influence on the period of the
 * generator.  Note: the deg*(2**deg - 1) is an approximation only good for
 * large deg, when the period of the shift register is the dominant factor.
 * With deg equal to seven, the period is actually much longer than the
 * 7*(2**7 - 1) predicted by this formula.
 *
 * Modified 28 December 1994 by Jacob S. Rosenberg.
 * The following changes have been made:
 * All references to the type u_int have been changed to unsigned long.
 * All references to type int have been changed to type long.  Other
 * cleanups have been made as well.  A warning for both initstate and
 * setstate has been inserted to the effect that on Sparc platforms
 * the 'arg_state' variable must be forced to begin on word boundaries.
 * This can be easily done by casting a long integer array to char *.
 * The overall logic has been left STRICTLY alone.  This software was
 * tested on both a VAX and Sun SpacsStation with exactly the same
 * results.  The new version and the original give IDENTICAL results.
 * The new version is somewhat faster than the original.  As the
 * documentation says:  "By default, the package runs with 128 bytes of
 * state information and generates far better random numbers than a linear
 * congruential generator.  If the amount of state information is less than
 * 32 bytes, a simple linear congruential R.N.G. is used."  For a buffer of
 * 128 bytes, this new version runs about 19 percent faster and for a 16
 * byte buffer it is about 5 percent faster.
 */

/*
 * For each of the currently supported random number generators, we have a
 * break value on the amount of state information (you need at least this
 * many bytes of state info to support this random number generator), a degree
 * for the polynomial (actually a trinomial) that the R.N.G. is based on, and
 * the separation between the two lower order coefficients of the trinomial.

 * Juergen Perlinger, 2008-11-12
 * Add support for full calendar calculatios. If the day-of-year is provided
 * (that is, not zero) it will be used instead of month and day-of-month;
 * otherwise a full turn through the calendar calculations will be taken.
 *
 * I know that Harlan Stenn likes to see assertions in production code, and I
 * agree there, but it would be a tricky thing here. The algorithm is quite
 * capable of producing sensible answers even to seemingly weird inputs: the
 * date -03-00, the 0.th March of the year, will be automtically
 * treated as the last day of February, no matter whether the year is a leap
 * year or not. So adding constraints is merely for the benefit of the callers,
 * because the only thing we can check for consistency is our input, produced
 * by somebody else.
 *
 * BTW: A total roundtrip using 'caljulian' would be a quite shaky thing:
 * Because of the truncation of the NTP time stamp to 32 bits and the epoch
 * unfolding around the current time done by 'caljulian' the roundtrip does
 * *not* necessarily reproduce the input, especially if the time spec is more
 * than 68 years off from the current time...

 * This implementation of mktime is lifted straight from the NetBSD (BSD 4.4)
 * version.  I modified it slightly to divorce it from the internals of the
 * ctime library.  Thus this version can't use details of the internal
 * timezone state file to figure out strange unnormalized struct tm values,
 * as might result from someone doing date math on the tm struct then passing
 * it to mktime.
 *
 * It just does as well as it can at normalizing the tm input, then does a
 * binary search of the time space using the system's localtime() function.
 *
 * The original binary search was defective in that it didn't consider the
 * setting of tm_isdst when comparing tm values, causing the search to be
 * flubbed for times near the dst/standard time changeover.  The original
 * code seems to make up for this by grubbing through the timezone info
 * whenever the binary search barfed.  Since I don't have that luxury in
 * portable code, I have to take care of tm_isdst in the comparison routine.
 * This requires knowing how many minutes offset dst is from standard time.
 *
 * So, if you live somewhere in the world where dst is not 60 minutes offset,
 * and your vendor doesn't supply mktime(), you'll have to edit this variable
 * by hand.  Sorry about that.

#
# depsver.mf	included in Makefile.am for directories with .deps
#
# When building in the same directory with sources that change over
# time, such as when tracking using bk, the .deps files can become
# stale with respect to moved, deleted, or superceded headers.  Most
# commonly, this would exhibit as make reporting a failure to make a
# header file which is no longer in the location given.  To address
# this issue, we use a deps-ver file which is updated with each change
# that breaks old .deps files.  A copy of deps-ver is made into
# $(DEPDIR) if not already present.  If $(DEPDIR)/deps-ver is present
# with different contents than deps-ver, we make clean to ensure all
# .o files built before the incompatible change are rebuilt along with
# their updated .deps files, then remove $(DEPDIR) and recreate it as
# empty stubs.
#
# It is normal when configured with --disable-dependency-tracking for
# the DEPDIR to not have been created.  For this reason, we use the
# intermediate target .deps-ver, which invokes make recursively if
# DEPDIR exists.
#
# If you modify depsver.mf, please make the changes to the master
# copy, the one in sntp is copied by the bootstrap script from it.
#
# This comment block follows rather than leads the related code so that
# it stays with it in the generated Makefile.in and Makefile.
#

# Tell versions [3.59,3.63) of GNU make to not export all variables.
# Otherwise a system limit (for SysV at least) may be exceeded.

   Works by periodic extension of the ntp time stamp in the NTP epoch.  If the
   'time_t' is 32 bit, use solar cycle warping to get the value in a suitable
   range. Also uses solar cycle warping to work around really buggy
   implementations of 'gmtime()' / 'localtime()' that cannot work with a
   negative time value, that is, times before 1970-01-01. (MSVCRT...)

   Apart from that we're assuming that the localtime/gmtime library functions

/* solar cycle in secs, unsigned secs and years. And the cycle limits.
**
** And an explanation. The julian calendar repeats ever 28 years, because it's
** the LCM of 7 and 4, the week and leap year cycles. This is called a 'solar
** cycle'. The gregorian calendar does the same as long as no centennial year
** (divisible by 100, but not 400) goes in the way. So between 1901 and 2099
** (inclusive) we can warp time stamps by 28 years to make them suitable for
** localtime() and gmtime() if we have trouble. Of course this will play
** hubbubb with the DST zone switches, so we should do it only if necessary;
** but as we NEED a proper conversion to dates via gmtime() we should try to
** cope with as many idiosyncrasies as possible.

/*! \file isc/symtab.h
 * \brief Provides a simple memory-based symbol table.
 *
 * Keys are C strings, and key comparisons are case-insensitive.  A type may
 * be specified when looking up, defining, or undefining.  A type value of
 * 0 means "match any type"; any other value will only match the given
 * type.
 *
 * It's possible that a client will attempt to define a 
 * tuple when a tuple with the given key and type already exists in the table.
 * What to do in this case is specified by the client.  Possible policies are:
 *
 *\li	#isc_symexists_reject	Disallow the define, returning #ISC_R_EXISTS
 *\li	#isc_symexists_replace	Replace the old value with the new.  The
 *				undefine action (if provided) will be called
 *				with the old  tuple.
 *\li	#isc_symexists_add	Add the new tuple, leaving the old tuple in
 *				the table.  Subsequent lookups will retrieve
 *				the most-recently-defined tuple.
 *
 * A lookup of a key using type 0 will return the most-recently defined
 * symbol with that key.  An undefine of a key using type 0 will undefine the
 * most-recently defined symbol with that key.  Trying to define a key with
 * type 0 is illegal.
 *
 * The symbol table library does not make a copy the key field, so the
 * caller must ensure that any key it passes to isc_symtab_define() will not
 * change until it calls isc_symtab_undefine() or isc_symtab_destroy().
 *
 * A user-specified action will be called (if provided) when a symbol is
 * undefined.  It can be used to free memory associated with keys and/or
 * values.

/*! \file isc/hash.h
 *
 * \brief The hash API
 *	provides an unpredictable hash value for variable length data.
 *	A hash object contains a random vector (which is hidden from clients
 *	of this API) to make the actual hash value unpredictable.
 *
 *	The algorithm used in the API guarantees the probability of hash
 *	collision; in the current implementation, as long as the values stored
 *	in the random vector are unpredictable, the probability of hash
 *	collision between arbitrary two different values is at most 1/2^16.
 *
 *	Although the API is generic about the hash keys, it mainly expects
 *	DNS names (and sometimes IPv4/v6 addresses) as inputs.  It has an
 *	upper limit of the input length, and may run slow to calculate the
 *	hash values for large inputs.
 *
 *	This API is designed to be general so that it can provide multiple
 *	different hash contexts that have different random vectors.  However,
 *	it should be typical to have a single context for an entire system.
 *	To support such cases, the API also provides a single-context mode.
 *
 * \li MP:
 *	The hash object is almost read-only.  Once the internal random vector
 *	is initialized, no write operation will occur, and there will be no
 *	need to lock the object to calculate actual hash values.
 *
 * \li Reliability:
 *	In some cases this module uses low-level data copy to initialize the
 *	random vector.  Errors in this part are likely to crash the server or
 *	corrupt memory.
 *
 * \li Resources:
 *	A buffer, used as a random vector for calculating hash values.
 *
 * \li Security:
 *	This module intends to provide unpredictable hash values in
 *	adversarial environments in order to avoid denial of service attacks
 *	to hash buckets.
 *	Its unpredictability relies on the quality of entropy to build the
 *	random vector.
 *
 * \li Standards:
 *	None.

#ifndef ISC_FSACCESS_H
#define ISC_FSACCESS_H 1

/*! \file isc/fsaccess.h
 * \brief The ISC filesystem access module encapsulates the setting of file
 * and directory access permissions into one API that is meant to be
 * portable to multiple operating systems.
 *
 * The two primary operating system flavors that are initially accommodated
 * are POSIX and Windows NT 4.0 and later.  The Windows NT access model is
 * considerable more flexible than POSIX's model (as much as I am loathe to
 * admit it), and so the ISC API has a higher degree of complexity than would
 * be needed to simply address POSIX's needs.
 *
 * The full breadth of NT's flexibility is not available either, for the
 * present time.  Much of it is to provide compatibility with what Unix
 * programmers are expecting.  This is also due to not yet really needing all
 * of the functionality of an NT system (or, for that matter, a POSIX system)
 * in BIND9, and so resolving how to handle the various incompatibilities has
 * been a purely theoretical exercise with no operational experience to
 * indicate how flawed the thinking may be.
 *
 * Some of the more notable dumbing down of NT for this API includes:
 *
 *\li   Each of FILE_READ_DATA and FILE_READ_EA are set with #ISC_FSACCESS_READ.
 *
 * \li  All of FILE_WRITE_DATA, FILE_WRITE_EA and FILE_APPEND_DATA are
 *     set with #ISC_FSACCESS_WRITE.  FILE_WRITE_ATTRIBUTES is not set
 *     so as to be consistent with Unix, where only the owner of the file
 *     or the superuser can change the attributes/mode of a file.
 *
 * \li  Both of FILE_ADD_FILE and FILE_ADD_SUBDIRECTORY are set with
 *     #ISC_FSACCESS_CREATECHILD.  This is similar to setting the WRITE
 *     permission on a Unix directory.
 *
 * \li  SYNCHRONIZE is always set for files and directories, unless someone
 *     can give me a reason why this is a bad idea.
 *
 * \li  READ_CONTROL and FILE_READ_ATTRIBUTES are always set; this is
 *     consistent with Unix, where any file or directory can be stat()'d
 *     unless the directory path disallows complete access somewhere along
 *     the way.
 *
 * \li  WRITE_DAC is only set for the owner.  This too is consistent with
 *     Unix, and is tighter security than allowing anyone else to be
 *     able to set permissions.
 *
 * \li  DELETE is only set for the owner.  On Unix the ability to delete
 *     a file is controlled by the directory permissions, but it isn't
 *     currently clear to me what happens on NT if the directory has
 *     FILE_DELETE_CHILD set but a file within it does not have DELETE
 *     set.  Always setting DELETE on the file/directory for the owner
 *     gives maximum flexibility to the owner without exposing the
 *     file to deletion by others.
 *
 * \li  WRITE_OWNER is never set.  This too is consistent with Unix,
 *     and is also tighter security than allowing anyone to change the
 *     ownership of the file apart from the superu..ahem, Administrator.
 *
 * \li  Inheritance is set to NO_INHERITANCE.
 *
 * Unix's dumbing down includes:
 *
 * \li  The sticky bit cannot be set.
 *
 * \li  setuid and setgid cannot be set.
 *
 * \li  Only regular files and directories can be set.
 *
 * The rest of this comment discusses a few of the incompatibilities
 * between the two systems that need more thought if this API is to
 * be extended to accommodate them.
 *
 * The Windows standard access right "DELETE" doesn't have a direct
 * equivalent in the Unix world, so it isn't clear what should be done
 * with it.
 *
 * The Unix sticky bit is not supported.  While NT does have a concept
 * of allowing users to create files in a directory but not delete or
 * rename them, it does not have a concept of allowing them to be deleted
 * if they are owned by the user trying to delete/rename.  While it is
 * probable that something could be cobbled together in NT 5 with inheritance,
 * it can't really be done in NT 4 as a single property that you could
 * set on a directory.  You'd need to coordinate something with file creation
 * so that every file created had DELETE set for the owner but noone else.
 *
 * On Unix systems, setting #ISC_FSACCESS_LISTDIRECTORY sets READ.
 * ... setting either #ISC_FSACCESS_CREATECHILD or #ISC_FSACCESS_DELETECHILD
 *      sets WRITE.
 * ... setting #ISC_FSACCESS_ACCESSCHILD sets EXECUTE.
 *
 * On NT systems, setting #ISC_FSACCESS_LISTDIRECTORY sets FILE_LIST_DIRECTORY.
 * ... setting #ISC_FSACCESS_CREATECHILD sets FILE_CREATE_CHILD independently.
 * ... setting #ISC_FSACCESS_DELETECHILD sets FILE_DELETE_CHILD independently.
 * ... setting #ISC_FSACCESS_ACCESSCHILD sets FILE_TRAVERSE.
 *
 * Unresolved:							XXXDCL
 * \li  What NT access right controls the ability to rename a file?
 * \li  How does DELETE work?  If a directory has FILE_DELETE_CHILD but a
 *      file or directory within it does not have DELETE, is that file
 *	or directory deletable?
 * \li  To implement isc_fsaccess_get(), mapping an existing Unix permission
 * 	mode_t back to an isc_fsaccess_t is pretty trivial; however, mapping
 *	an NT DACL could be impossible to do in a responsible way.
 * \li  Similarly, trying to implement the functionality of being able to
 *	say "add group writability to whatever permissions already exist"
 *	could be tricky on NT because of the order-of-entry issue combined
 *	with possibly having one or more matching ACEs already explicitly
 *	granting or denying access.  Because this functionality is
 *	not yet needed by the ISC, no code has been written to try to
 * 	solve this problem.

 * This code is in the public domain; do with it what you wish.
 *
 * Equivalent code is available from RSA Data Security, Inc.

 * except that you don't need to include two pages of legalese
 * with every copy.
 *
 * To compute the message digest of a chunk of bytes, declare an
 * MD5Context structure, pass it to MD5Init, call MD5Update as
 * needed on buffers full of bytes, and then call MD5Final, which
 * will fill a supplied 16-byte array with the digest.
 *
 * Changed so as no longer to depend on Colin Plumb's `usual.h'
 * header definitions; now uses stuff from dpkg's config.h

 * \brief A buffer is a region of memory, together with a set of related subregions.
 * Buffers are used for parsing and I/O operations.
 *
 * The 'used region' and the 'available' region are disjoint, and their
 * union is the buffer's region.  The used region extends from the beginning
 * of the buffer region to the last used byte.  The available region
 * extends from one byte greater than the last used byte to the end of the
 * buffer's region.  The size of the used region can be changed using various
 * buffer commands.  Initially, the used region is empty.
 *
 * The used region is further subdivided into two disjoint regions: the
 * 'consumed region' and the 'remaining region'.  The union of these two
 * regions is the used region.  The consumed region extends from the beginning
 * of the used region to the byte before the 'current' offset (if any).  The
 * 'remaining' region the current pointer to the end of the used
 * region.  The size of the consumed region can be changed using various
 * buffer commands.  Initially, the consumed region is empty.
 *
 * The 'active region' is an (optional) subregion of the remaining region.
 * It extends from the current offset to an offset in the remaining region
 * that is selected with isc_buffer_setactive().  Initially, the active region
 * is empty.  If the current offset advances beyond the chosen offset, the
 * active region will also be empty.

 * \brief The entropy API
 *
 * \li MP:
 *	The entropy object is locked internally.  All callbacks into
 *	application-provided functions (for setup, gathering, and
 *	shutdown of sources) are guaranteed to be called with the
 *	entropy API lock held.  This means these functions are
 *	not permitted to call back into the entropy API.
 *
 * \li Reliability:
 *	No anticipated impact.
 *
 * \li Resources:
 *	A buffer, used as an entropy pool.
 *
 * \li Security:
 *	While this code is believed to implement good entropy gathering
 *	and distribution, it has not been reviewed by a cryptographic
 *	expert.
 *	Since the added entropy is only as good as the sources used,
 *	this module could hand out bad data and never know it.
 *
 * \li Standards:
 *	None.

 * A bitstring is a packed array of bits, stored in a contiguous

 * is the high bit of the first octet.  The "least significant bit" of a
 * bitstring is the low bit of the last octet.
 *
 * Two bit numbering schemes are supported, "msb0" and "lsb0".
 *
 * In the "msb0" scheme, bit number 0 designates the most significant bit,
 * and any padding bits required to make the bitstring a multiple of 8 bits
 * long are added to the least significant end of the last octet.
 *
 * In the "lsb0" scheme, bit number 0 designates the least significant bit,
 * and any padding bits required to make the bitstring a multiple of 8 bits
 * long are added to the most significant end of the first octet.
 *
 * E.g., consider the bitstring "11010001111".  This bitstring is 11 bits
 * long and will take two octets.  Let "p" denote a pad bit.  In the msb0

/*****
 ***** Module Info
 *****/

/*! \file isc/timer.h
 * \brief Provides timers which are event sources in the task system.
 *
 * Three types of timers are supported:
 *
 *\li	'ticker' timers generate a periodic tick event.
 *
 *\li	'once' timers generate an idle timeout event if they are idle for too
 *	long, and generate a life timeout event if their lifetime expires.
 *	They are used to implement both (possibly expiring) idle timers and
 *	'one-shot' timers.
 *
 *\li	'limited' timers generate a periodic tick event until they reach
 *	their lifetime when they generate a life timeout event.
 *
 *\li	'inactive' timers generate no events.
 *
 * Timers can change type.  It is typical to create a timer as
 * an 'inactive' timer and then change it into a 'ticker' or
 * 'once' timer.
 *
 *\li MP:
 *	The module ensures appropriate synchronization of data structures it
 *	creates and manipulates.
 *	Clients of this module must not be holding a timer's task's lock when
 *	making a call that affects that timer.  Failure to follow this rule
 *	can result in deadlock.
 *	The caller must ensure that isc_timermgr_destroy() is called only
 *	once for a given manager.
 *
 * \li Reliability:
 *	No anticipated impact.
 *
 * \li Resources:
 *	TBS
 *
 * \li Security:
 *	No anticipated impact.
 *
 * \li Standards:
 *	None.

 * \brief ISC Application Support
 *
 * Dealing with program termination can be difficult, especially in a
 * multithreaded program.  The routines in this module help coordinate
 * the shutdown process.  They are used as follows by the initial (main)
 * thread of the application:
 *
 *\li		isc_app_start();	Call very early in main(), before
 *					any other threads have been created.
 *
 *\li		isc_app_run();		This will post any on-run events,
 *					and then block until application
 *					shutdown is requested.  A shutdown
 *					request is made by calling
 *					isc_app_shutdown(), or by sending
 *					SIGINT or SIGTERM to the process.
 *					After isc_app_run() returns, the
 *					application should shutdown itself.
 *
 *\li		isc_app_finish();	Call very late in main().
 *
 * Applications that want to use SIGHUP/isc_app_reload() to trigger reloading
 * should check the result of isc_app_run() and call the reload routine if
 * the result is ISC_R_RELOAD.  They should then call isc_app_run() again
 * to resume waiting for reload or termination.
 *
 * Use of this module is not required.  In particular, isc_app_start() is
 * NOT an ISC library initialization routine.
 *
 * \li MP:
 *	Clients must ensure that isc_app_start(), isc_app_run(), and
 *	isc_app_finish() are called at most once.  isc_app_shutdown()
 *	is safe to use by any thread (provided isc_app_start() has been
 *	called previously).

 *	No anticipated impact.

 *	None.

 * \brief The task system provides a lightweight execution context, which is

 * When a task's event queue is non-empty, the

 *
 * \section purge Purging and Unsending
 *
 * Events which have been queued for a task but not delivered may be removed
 * from the task's event queue by purging or unsending.
 *
 * With both types, the caller specifies a matching pattern that selects
 * events based upon their sender, type, and tag.
 *
 * Purging calls isc_event_free() on the matching events.
 *
 * Unsending returns a list of events that matched the pattern.
 * The caller is then responsible for them.
 *
 * Consumers of events should purge, not unsend.
 *
 * Producers of events often want to remove events when the caller indicates
 * it is no longer interested in the object, e.g. by canceling a timer.
 * Sometimes this can be done by purging, but for some event types, the
 * calls to isc_event_free() cause deadlock because the event free routine
 * wants to acquire a lock the caller is already holding.  Unsending instead
 * of purging solves this problem.  As a general rule, producers should only
 * unsend events which they have sent.

/*
 * When some architecture-dependent atomic operations are available,
 * rwlock can be more efficient than the generic algorithm defined below.
 * The basic algorithm is described in the following URL:
 *   http://www.cs.rochester.edu/u/scott/synchronization/pseudocode/rw.html
 *
 * The key is to use the following integer variables modified atomically:
 *   write_requests, write_completions, and cnt_and_flag.
 *
 * write_requests and write_completions act as a waiting queue for writers
 * in order to ensure the FIFO order.  Both variables begin with the initial
 * value of 0.  When a new writer tries to get a write lock, it increments
 * write_requests and gets the previous value of the variable as a "ticket".
 * When write_completions reaches the ticket number, the new writer can start
 * writing.  When the writer completes its work, it increments
 * write_completions so that another new writer can start working.  If the
 * write_requests is not equal to write_completions, it means a writer is now
 * working or waiting.  In this case, a new readers cannot start reading, or
 * in other words, this algorithm basically prefers writers.
 *
 * cnt_and_flag is a "lock" shared by all readers and writers.  This integer
 * variable is a kind of structure with two members: writer_flag (1 bit) and
 * reader_count (31 bits).  The writer_flag shows whether a writer is working,
 * and the reader_count shows the number of readers currently working or almost
 * ready for working.  A writer who has the current "ticket" tries to get the
 * lock by exclusively setting the writer_flag to 1, provided that the whole
 * 32-bit is 0 (meaning no readers or writers working).  On the other hand,
 * a new reader tries to increment the "reader_count" field provided that
 * the writer_flag is 0 (meaning there is no writer working).
 *
 * If some of the above operations fail, the reader or the writer sleeps
 * until the related condition changes.  When a working reader or writer
 * completes its work, some readers or writers are sleeping, and the condition
 * that suspended the reader or writer has changed, it wakes up the sleeping
 * readers or writers.
 *
 * As already noted, this algorithm basically prefers writers.  In order to
 * prevent readers from starving, however, the algorithm also introduces the
 * "writer quota" (Q).  When Q consecutive writers have completed their work,
 * suspending readers, the last writer will wake up the readers, even if a new
 * writer is waiting.
 *
 * Implementation specific note: due to the combination of atomic operations
 * and a mutex lock, ordering between the atomic operation and locks can be
 * very sensitive in some cases.  In particular, it is generally very important
 * to check the atomic variable that requires a reader or writer to sleep after
 * locking the mutex and before actually sleeping; otherwise, it could be very
 * likely to cause a deadlock.  For example, assume "var" is a variable
 * atomically modified, then the corresponding code would be:
 *	if (var == need_sleep) {
 *		LOCK(lock);
 *		if (var == need_sleep)
 *			WAIT(cond, lock);
 *		UNLOCK(lock);
 *	}
 * The second check is important, since "var" is protected by the atomic
 * operation, not by the mutex, and can be changed just before sleeping.
 * (The first "if" could be omitted, but this is also important in order to
 * make the code efficient by avoiding the use of the mutex unless it is
 * really necessary.)

 *
 * It ensures that #INADDR_LOOPBACK, #INADDR_ANY, #IN6ADDR_ANY_INIT,
 * in6addr_any, and in6addr_loopback are available.
 *
 * It ensures that IN_MULTICAST() is available to check for multicast
 * addresses.

 * as follows: the socket watcher is first initialized with the state of

 * event occurs.  When it wakes up for a socket I/O event, it moves to the
 * poll_active state, and sets the poll timeout to a short period
 * (ISC_SOCKET_POLLWATCH_TIMEOUT msec).  If timeout occurs in this state, the
 * watcher goes to the poll_checking state with the same timeout period.
 * In this state, the watcher tries to detect whether this is a break
 * during intermittent events or the kernel bug is triggered.  If the next
 * polling reports an event within the short period, the previous timeout is
 * likely to be a kernel bug, and so the watcher goes back to the active state.
 * Otherwise, it moves to the idle state again.
 *
 * It's not clear whether this is a thread-related bug, but since we've only

 *  and everything between the quotes is left untouched (including 
 *  whitespace)
 *  Example:
 *     server host name =   hello world!
 *  will result in a field string "SERVERHOSTNAME" and a value
 *  of "hello world!".

.SH NAME
ntpsnmpd \- NTP SNMP MIB agent
.SH SYNOPSIS
.B ntpsnmpd
.\" Mixture of short (flag) options and long options
.RB [ \-\fIflag\fP " [\fIvalue\fP]]... [" \--\fIopt-name\fP " [[=| ]\fIvalue\fP]]..."
.PP
All arguments must be options.
.SH "DESCRIPTION"
This manual page briefly documents the \fBntpsnmpd\fP command.
Its description is not documented.
.SH OPTIONS
.TP
.BR \-n ", " \--nofork
Do not fork.
.sp

.TP
.BR \-p ", " \--syslog
Log to syslog().
.sp

.TP
.BR \--agentxsocket "=\fIstring\fP"
The socket address ntpsnmpd uses to connect to net-snmpd.
The default \fIstring\fP for this option is:
.ti +4
 unix:/var/agentx/master
.sp
[:]
The default is the Unix Domain socket "unix:/var/agentx/master". Another common alternative is tcp:localhost:705.
.TP
.BR \-? , " \--help"
Display extended usage information and exit.
.TP
.BR \-! , " \--more-help"
Extended usage information passed thru pager.
.TP
.BR \-> " [\fIrcfile\fP]," " \--save-opts" "[=\fIrcfile\fP]"
Save the option state to \fIrcfile\fP.  The default is the \fIlast\fP
configuration file listed in the \fBOPTION PRESETS\fP section, below.
.TP
.BR \-< " \fIrcfile\fP," " \--load-opts" "=\fIrcfile\fP," " \--no-load-opts"
Load options from \fIrcfile\fP.
The \fIno-load-opts\fP form will disable the loading
of earlier RC/INI files.  \fI--no-load-opts\fP is handled early,
out of order.
.TP
.BR \- " [{\fIv|c|n\fP}]," " \--version" "[=\fI{v|c|n}\fP]"
Output version of program and exit.  The default mode is `v', a simple
version.  The `c' mode will print copyright information and `n' will
print the full copyright notice.
.SH OPTION PRESETS
Any option that is not marked as \fInot presettable\fP may be preset
by loading values from configuration ("RC" or ".INI") file(s) and values from
environment variables named:
.nf
  \fBNTPSNMPD_\fP or \fBNTPSNMPD\fP
.fi
.ad
The environmental presets take precedence (are processed later than)
the configuration files.
The \fIhomerc\fP files are "\fI$HOME\fP", and "\fI.\fP".
If any of these are directories, then the file \fI.ntprc\fP
is searched for within those directories.

#
# depsver.mf	included in Makefile.am for directories with .deps
#
# When building in the same directory with sources that change over
# time, such as when tracking using bk, the .deps files can become
# stale with respect to moved, deleted, or superceded headers.  Most
# commonly, this would exhibit as make reporting a failure to make a
# header file which is no longer in the location given.  To address
# this issue, we use a deps-ver file which is updated with each change
# that breaks old .deps files.  A copy of deps-ver is made into
# $(DEPDIR) if not already present.  If $(DEPDIR)/deps-ver is present
# with different contents than deps-ver, we make clean to ensure all
# .o files built before the incompatible change are rebuilt along with
# their updated .deps files, then remove $(DEPDIR) and recreate it as
# empty stubs.
#
# It is normal when configured with --disable-dependency-tracking for
# the DEPDIR to not have been created.  For this reason, we use the
# intermediate target .deps-ver, which invokes make recursively if
# DEPDIR exists.
#
# If you modify depsver.mf, please make the changes to the master
# copy, the one in sntp is copied by the bootstrap script from it.
#
# This comment block follows rather than leads the related code so that
# it stays with it in the generated Makefile.in and Makefile.
#

# Tell versions [3.59,3.63) of GNU make to not export all variables.
# Otherwise a system limit (for SysV at least) may be exceeded.

 *
 *  The NTP SNMP daemon is an Agent X subagent application that 
 *  registers itself with a running SNMP Agent X master process running
 *  on the same machine on port TCP 705. It utilizes the libntqp library
 *  which accesses status and general data of a running ntpd process on
 *  the same machine and enables the user to monitor the status of a
 *  ntp daemon process via SNMP. 
 *
 *  This started as a Google Summer of Code 2008 project, 
 *  including the ntpsnmpd sub agent and the libntpq library.

Installation Guides:

- install net-snmp from source (configure, make;, make install)
- edit the snmpd configuration file (/usr/local/share/snmp/snmpd.conf):
  add the lines
   master agentx
   agentXSocket   tcp:localhost:705
  and check which read-only community is configured (should be "rocommunity  public")  
- start snmpd (sudo /usr/local/sbin/snmpd) and check that it is running correctly by running the command
  snmpwalk -v2c -c public localhost
  (which should output a lot of data values for the supported built-in MIBs of net-snmp)
- build the libntpq and the libntp library
- build the ntpsnmpd application (make) and run it (./ntpsnmpd)
- now you can run 
   snmpwalk -v2c -c public localhost enterprises.5597.99
  which should give you a list of all currently supported NTP MIB objects and their current values
  
Please note that currently I use a private MIB OID (enterprises.5597 is the Meinberg top level OEM OID and 99 is my temporary working space for this project). 
The final OID has to be registered with IANA and this is done by the RFC Editor when the NTPv4 MIB RFC is standardized. 
I will try to do this earlier in order to be able to have a working solution at the end of this project.

In its current state the daemon supports these objects:

ntpEntSoftwareName
ntpEntSoftwareVersion
ntpEntSoftwareVersionVal
ntpEntSoftwareVendor
ntpEntSystemType
ntpEntTimeResolution
ntpEntTimeResolutionVal
ntpEntTimePrecision
ntpEntTimePrecisionVal
ntpEntTimeDistance

They all use the libntpq library to access information from the ntpd instance with mode 6 packets.

Next step is to implement the status section of the MIB (section 2).

    Simple Network Time Protocol User Manual
    


    This document describes the use of the NTP Project's sntp program,
that can be used to query a Network Time Protocol (NTP) server and
display the time offset of the system clock relative to the server
clock.  Run as root, it can correct the system clock to this offset as
well.  It can be run as an interactive command or from a cron job.

  
    This document applies to version 4.2.6p5 of sntp.

  
    The program implements the SNTP protocol as defined by RFC 5905, the NTPv4
IETF specification.

    Description
    


    By default, sntp writes the local data and time (i.e., not UTC) to the
standard output in the format:


         1996 Oct 15 20:17:25.123 +4.567 +/- 0.089 secs

    
  
    where the +4.567 +/- 0.089 secs indicates the time offset and
error bound of the system clock relative to the server clock.


    

    


    

    


    Invoking sntp
    


    
sntp
can be used as a SNTP client to query a NTP or SNTP server and either display
the time or set the local system's time (given suitable privilege).  It can be
run as an interactive command or in a
cron
job.

  
    NTP (the Network Time Protocol) and SNTP (the Simple Network Time Protocol)
are defined and described by RFC 5905.

  
    The default is to write the estimated correct local date and time (i.e. not
UTC) to the standard output in a format like

         1996-10-15 20:17:25.123 (+0800) +4.567 +/- 0.089 secs

    
  
    where the

         +4.567 +/- 0.089 secs

    
  
    indicates the local clock is 4.567 seconds behind the correct time
(so 4.567 seconds must be added to the local clock to get it to be correct),
and the (local) time of
1996-10-15 20:17:25.123
can be converted to UTC time by adding 8 hours and 0 minutes, and
is believed to be correct to within
+/- 0.089
seconds.

The following option preset mechanisms are supported:
 - reading file $HOME/.ntprc
 - reading file ./.ntprc
 - examining environment variables named SNTP_*

sntp implements the Simple Network Time Protocol, and is used to query an
NTP or SNTP server and either display the time or set the local system's
time (given suitable privilege).

It can be run interactively from the command line or as a cron job.

NTP and SNTP are defined by RFC 5905, which obsoletes RFC 4330 and RFC
1305.

This is the “specify a keyfile. sntp will look in this file for the key specified with -a” option. 
This option specifies the keyfile. SNTP will search for the key specified with -a keyno in this
file. Key files follow the following format:

  
    keyid keytype key

  
    Where	keyid is a number identifying this key
keytype is one of the follow:
S  Key in 64 Bit hexadecimal number as specified in in the DES specification. 
N  Key in 64 Bit hexadecimal number as specified in the NTP standard. 
A  Key in a 1-to-8 character ASCII string. 
M  Key in a 1-to-8 character ASCII string using the MD5 authentication scheme.

When waiting for a broadcast packet SNTP will wait the number
of seconds specified before giving up.  Default 68 seconds.


    

    


    

    



    Usage
    


    The simplest use of this program is as an unprivileged command to
check the current time, offset, and error in the local clock. 
For example:


        sntp ntpserver.somewhere

    
  
    With suitable privilege, it can be run as a command or in a
crom job to reset the local clock from a reliable server, like
the ntpdate and rdate commands. 
For example:


        sntp -a ntpserver.somewhere

@code{sntp}
can be used as a SNTP client to query a NTP or SNTP server and either display
the time or set the local system's time (given suitable privilege).  It can be
run as an interactive command or in a
@code{cron}
job.

NTP (the Network Time Protocol) and SNTP (the Simple Network Time Protocol)
are defined and described by RFC 5905.

@indent
The default is to write the estimated correct local date and time (i.e. not
UTC) to the standard output in a format like
@example
1996-10-15 20:17:25.123 (+0800) +4.567 +/- 0.089 secs
@end example
where the
@example
+4.567 +/- 0.089 secs
@end example
indicates the local clock is 4.567 seconds behind the correct time
(so 4.567 seconds must be added to the local clock to get it to be correct),
and the (local) time of
@code{1996-10-15 20:17:25.123}
can be converted to UTC time by adding 8 hours and 0 minutes, and
is believed to be correct to within
@code{+/- 0.089}
seconds.

The following option preset mechanisms are supported:
 - reading file $HOME/.ntprc
 - reading file ./.ntprc
 - examining environment variables named SNTP_*

sntp implements the Simple Network Time Protocol, and is used to query an
NTP or SNTP server and either display the time or set the local system's
time (given suitable privilege).

It can be run interactively from the command line or as a cron job.

NTP and SNTP are defined by RFC 5905, which obsoletes RFC 4330 and RFC
1305.

@node sntp adjtime
@subsection adjtime option (-j)
@cindex sntp-adjtime

This is the ``set (slew) the time with adjtime()'' option.

This option has some usage constraints.  It:
@itemize @bullet
@item
must not appear in combination with any of the following options:
settod.
@end itemize



@node sntp authentication
@subsection authentication option (-a)
@cindex sntp-authentication

This is the ``enable authentication with the key auth-keynumber'' option.
This option enables authentication using the key specified in this option's argument.
The argument of this option is the keyid, a number specified in the keyfile as this
key's identifier. See the keyfile option (-k) for more details.

@node sntp broadcast
@subsection broadcast option (-b)
@cindex sntp-broadcast

This is the ``use broadcasts to the address specified for synchronisation'' option.
If specified SNTP will listen to the specified broadcast address
for NTP broadcasts.  The default maximum wait time,
68 seconds, can be modified with -t.

@node sntp ipv4
@subsection ipv4 option (-4)
@cindex sntp-ipv4

This is the ``force ipv4 dns name resolution'' option.

This option has some usage constraints.  It:
@itemize @bullet
@item
must not appear in combination with any of the following options:
ipv6.
@end itemize

Force DNS resolution of the following host names on the command line
to the IPv4 namespace.

@node sntp ipv6
@subsection ipv6 option (-6)
@cindex sntp-ipv6

This is the ``force ipv6 dns name resolution'' option.

This option has some usage constraints.  It:
@itemize @bullet
@item
must not appear in combination with any of the following options:
ipv4.
@end itemize

Force DNS resolution of the following host names on the command line
to the IPv6 namespace.

@node sntp keyfile
@subsection keyfile option (-k)
@cindex sntp-keyfile

This is the ``specify a keyfile. sntp will look in this file for the key specified with -a'' option.
This option specifies the keyfile. SNTP will search for the key specified with -a keyno in this
file. Key files follow the following format:

keyid keytype key

Where	keyid is a number identifying this key
keytype is one of the follow:
S  Key in 64 Bit hexadecimal number as specified in in the DES specification.
N  Key in 64 Bit hexadecimal number as specified in the NTP standard.
A  Key in a 1-to-8 character ASCII string.
M  Key in a 1-to-8 character ASCII string using the MD5 authentication scheme.

For more information see ntp.keys(5).

@node sntp kod
@subsection kod option (-K)
@cindex sntp-kod

This is the ``kod history filename'' option.
Specifies the filename to be used to persist the history of KoD
responses received from servers.  The default is
/var/db/ntp-kod.

@node sntp logfile
@subsection logfile option (-l)
@cindex sntp-logfile

This is the ``log to specified logfile'' option.

This option has some usage constraints.  It:
@itemize @bullet
@item
must not appear in combination with any of the following options:
syslog.
@end itemize

This option causes the client to write log messages to the specified
logfile.

@node sntp normalverbose
@subsection normalverbose option (-d)
@cindex sntp-normalverbose

This is the ``normal verbose'' option.
Diagnostic messages for non-fatal errors and a limited amount of
tracing should be written to standard error.  Fatal ones always
produce a diagnostic.  This option should be set when there is a
suspected problem with the server, network or the source.

@node sntp settod
@subsection settod option (-s)
@cindex sntp-settod

This is the ``set (step) the time with settimeofday()'' option.

This option has some usage constraints.  It:
@itemize @bullet
@item
must not appear in combination with any of the following options:
adjtime.
@end itemize



@node sntp syslog
@subsection syslog option (-p)
@cindex sntp-syslog

This is the ``logging with syslog'' option.

This option has some usage constraints.  It:
@itemize @bullet
@item
must not appear in combination with any of the following options:
logfile.
@end itemize

When this option is set all logging will be done using syslog.

@node sntp timeout
@subsection timeout option (-t)
@cindex sntp-timeout

This is the ``specify the number of seconds to wait for broadcasts'' option.
When waiting for a broadcast packet SNTP will wait the number
of seconds specified before giving up.  Default 68 seconds.

\`configure' configures sntp 4.2.6p5 to adapt to many kinds of systems.

Usage: $0 [OPTION]... [VAR=VALUE]...

To assign environment variables (e.g., CC, CFLAGS...), specify them as
VAR=VALUE.  See below for descriptions of some of the useful variables.

Defaults for the options are specified in brackets.

Configuration:
  -h, --help              display this help and exit
      --help=short        display options specific to this package
      --help=recursive    display the short help of all the included packages
  -V, --version           display version information and exit
  -q, --quiet, --silent   do not print \`checking ...' messages
      --cache-file=FILE   cache test results in FILE [disabled]
  -C, --config-cache      alias for \`--cache-file=config.cache'
  -n, --no-create         do not create output files
      --srcdir=DIR        find the sources in DIR [configure dir or \`..']

Installation directories:
  --prefix=PREFIX         install architecture-independent files in PREFIX
                          [$ac_default_prefix]
  --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
                          [PREFIX]

By default, \`make install' will install all the files in
\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
an installation prefix other than \`$ac_default_prefix' using \`--prefix',
for instance \`--prefix=\$HOME'.

For better control, use the options below.

Fine tuning of the installation directories:
  --bindir=DIR            user executables [EPREFIX/bin]
  --sbindir=DIR           system admin executables [EPREFIX/sbin]
  --libexecdir=DIR        program executables [EPREFIX/libexec]
  --sysconfdir=DIR        read-only single-machine data [PREFIX/etc]
  --sharedstatedir=DIR    modifiable architecture-independent data [PREFIX/com]
  --localstatedir=DIR     modifiable single-machine data [PREFIX/var]
  --libdir=DIR            object code libraries [EPREFIX/lib]
  --includedir=DIR        C header files [PREFIX/include]
  --oldincludedir=DIR     C header files for non-gcc [/usr/include]
  --datarootdir=DIR       read-only arch.-independent data root [PREFIX/share]
  --datadir=DIR           read-only architecture-independent data [DATAROOTDIR]
  --infodir=DIR           info documentation [DATAROOTDIR/info]
  --localedir=DIR         locale-dependent data [DATAROOTDIR/locale]
  --mandir=DIR            man documentation [DATAROOTDIR/man]
  --docdir=DIR            documentation root [DATAROOTDIR/doc/sntp]
  --htmldir=DIR           html documentation [DOCDIR]
  --dvidir=DIR            dvi documentation [DOCDIR]
  --pdfdir=DIR            pdf documentation [DOCDIR]
  --psdir=DIR             ps documentation [DOCDIR]

Program names:
  --program-prefix=PREFIX            prepend PREFIX to installed program names
  --program-suffix=SUFFIX            append SUFFIX to installed program names
  --program-transform-name=PROGRAM   run sed PROGRAM on installed program names

System types:
  --build=BUILD     configure for building on BUILD [guessed]
  --host=HOST       cross-compile to build programs to run on HOST [BUILD]

Optional Features:
  --disable-option-checking  ignore unrecognized --enable/--with options
  --disable-FEATURE       do not include FEATURE (same as --enable-FEATURE=no)
  --enable-FEATURE[=ARG]  include FEATURE [ARG=yes]
  --disable-dependency-tracking  speeds up one-time build
  --enable-dependency-tracking   do not reject slow dependency extractors
  --enable-shared[=PKGS]  build shared libraries [default=no]
  --enable-local-libopts  Force using the supplied libopts tearoff code
  --disable-libopts-install
                          Do not install libopts with client installation
  --disable-optional-args not wanting optional option args
  --enable-static[=PKGS]  build static libraries [default=yes]
  --enable-fast-install[=PKGS]
                          optimize for fast installation [default=yes]
  --disable-libtool-lock  avoid locking (might break parallel builds)
  --enable-ipv6           s use IPv6?


Optional Packages:
  --with-PACKAGE[=ARG]    use PACKAGE [ARG=yes]
  --without-PACKAGE       do not use PACKAGE (same as --with-PACKAGE=no)
  --with-autoopts-config  specify the config-info script
  --with-regex-header     a reg expr header is specified
  --with-libregex         libregex installation prefix
  --with-libregex-cflags  libregex compile flags
  --with-libregex-libs    libregex link command arguments
  --with-pic              try to use only PIC/non-PIC objects [default=use
                          both]
  --with-gnu-ld           assume the C compiler uses GNU ld [default=no]
  --with-sysroot=DIR Search for dependent libraries within DIR
                        (or the compiler's sysroot if not specified).
  --with-openssl-libdir   + =/something/reasonable
  --with-openssl-incdir   + =/something/reasonable
  --with-crypto           + =openssl
  --with-kame             - =/usr/local/v6
  --with-binsubdir        bin ={bin,sbin}

Some influential environment variables:
  CC          C compiler command
  CFLAGS      C compiler flags
  LDFLAGS     linker flags, e.g. -L if you have libraries in a
              nonstandard directory 
  LIBS        libraries to pass to the linker, e.g. -l
  CPPFLAGS    (Objective) C/C++ preprocessor flags, e.g. -I if
              you have headers in a nonstandard directory 
  CPP         C preprocessor

Use these variables to override the choices made by `configure' or to help
it to find libraries and programs with nonstandard names/locations.

Report bugs to the package provider.

dnl  HP-UX 11.31 on HPPA has a net/if.h that can't be compiled with gcc4
dnl  due to an incomplete type (a union) mpinfou used in an array.  gcc3
dnl  compiles it without complaint.  The mpinfou union is defined later
dnl  in the resulting preprocessed source than the spu_info array in
dnl  /usr/include/machine/sys/getppdp.h:
dnl	extern union mpinfou spu_info[];
dnl  triggering the error.  Our strategy is on HP-UX only, test for
dnl  net/netmp.h, which is the file included by net/if.h that leads to
dnl  getppdp.h.  If it is present but can't be compiled, try adding
dnl  a duplicate definition of mpinfou, which should then allow the
dnl  following net/if.h and net/if6.h tests to proceed normally.
dnl  Using net/netmp.h allows us to avoid polluting test results for
dnl  net/if.h.

#
# depsver.mf	included in Makefile.am for directories with .deps
#
# When building in the same directory with sources that change over
# time, such as when tracking using bk, the .deps files can become
# stale with respect to moved, deleted, or superceded headers.  Most
# commonly, this would exhibit as make reporting a failure to make a
# header file which is no longer in the location given.  To address
# this issue, we use a deps-ver file which is updated with each change
# that breaks old .deps files.  A copy of deps-ver is made into
# $(DEPDIR) if not already present.  If $(DEPDIR)/deps-ver is present
# with different contents than deps-ver, we make clean to ensure all
# .o files built before the incompatible change are rebuilt along with
# their updated .deps files, then remove $(DEPDIR) and recreate it as
# empty stubs.
#
# It is normal when configured with --disable-dependency-tracking for
# the DEPDIR to not have been created.  For this reason, we use the
# intermediate target .deps-ver, which invokes make recursively if
# DEPDIR exists.
#
# If you modify depsver.mf, please make the changes to the master
# copy, the one in sntp is copied by the bootstrap script from it.
#
# This comment block follows rather than leads the related code so that
# it stays with it in the generated Makefile.in and Makefile.

# Configuration subroutine to validate and canonicalize a configuration type.
# Supply the specified configuration type as an argument.
# If it is invalid, we print an error message on stderr and exit with code 1.
# Otherwise, we print the canonical config type on stdout and succeed.

#	CPU_TYPE-MANUFACTURER-OPERATING_SYSTEM
# or in some cases, the newer four-part form:
#	CPU_TYPE-MANUFACTURER-KERNEL-OPERATING_SYSTEM

#
# depsver.mf	included in Makefile.am for directories with .deps
#
# When building in the same directory with sources that change over
# time, such as when tracking using bk, the .deps files can become
# stale with respect to moved, deleted, or superceded headers.  Most
# commonly, this would exhibit as make reporting a failure to make a
# header file which is no longer in the location given.  To address
# this issue, we use a deps-ver file which is updated with each change
# that breaks old .deps files.  A copy of deps-ver is made into
# $(DEPDIR) if not already present.  If $(DEPDIR)/deps-ver is present
# with different contents than deps-ver, we make clean to ensure all
# .o files built before the incompatible change are rebuilt along with
# their updated .deps files, then remove $(DEPDIR) and recreate it as
# empty stubs.
#
# It is normal when configured with --disable-dependency-tracking for
# the DEPDIR to not have been created.  For this reason, we use the
# intermediate target .deps-ver, which invokes make recursively if
# DEPDIR exists.
#
# If you modify depsver.mf, please make the changes to the master
# copy, the one in sntp is copied by the bootstrap script from it.
#
# This comment block follows rather than leads the related code so that
# it stays with it in the generated Makefile.in and Makefile.
#

# Tell versions [3.59,3.63) of GNU make to not export all variables.
# Otherwise a system limit (for SysV at least) may be exceeded.

@top Simple Network Time Protocol User Manual

This document describes the use of the NTP Project's @code{sntp} program,
that can be used to query a Network Time Protocol (NTP) server and
display the time offset of the system clock relative to the server
clock.  Run as root, it can correct the system clock to this offset as
well.  It can be run as an interactive command or from a cron job.

This document applies to version @value{VERSION} of @code{sntp}.

The program implements the SNTP protocol as defined by RFC 5905, the NTPv4
IETF specification.

@node sntp Description
@comment  node-name,  next,  previous,  up
@section Description

By default, @code{sntp} writes the local data and time (i.e., not UTC) to the
standard output in the format:

@example
1996 Oct 15 20:17:25.123 +4.567 +/- 0.089 secs
@end example

where the +4.567 +/- 0.089 secs indicates the time offset and
error bound of the system clock relative to the server clock.

@include sntp-opts.texi

@node Usage
@comment  node-name,  next,  previous,  up
@section Usage

The simplest use of this program is as an unprivileged command to
check the current time, offset, and error in the local clock.
For example:

@example
sntp ntpserver.somewhere
@end example

With suitable privilege, it can be run as a command or in a
@code{crom} job to reset the local clock from a reliable server, like
the @code{ntpdate} and @code{rdate} commands.
For example:

@example
sntp -a ntpserver.somewhere
@end example

# In each case, ARG is the path to be converted from $build to $host format.
# The result will be available in $func_to_host_path_result.
#
# Path separators are also converted from $build format to $host format.  If
# ARG begins or ends with a path separator character, it is preserved (but
# converted to $host format) on output.
#
# All path conversion functions are named using the following convention:
#   file name conversion function    : func_convert_file_X_to_Y ()
#   path conversion function         : func_convert_path_X_to_Y ()
# where, for any given $build/$host combination the 'X_to_Y' value is the
# same.  If conversion functions are added for new $build/$host combinations,
# the two new functions must follow this pattern, or func_init_to_host_path_cmd
# will break.

"Usage: $progname [OPTION]... --mode=link LINK-COMMAND...

Link object files or libraries together to form another library, or to
create an executable program.

LINK-COMMAND is a command using the C compiler that you would use to create
a program from several object files.

The following components of LINK-COMMAND are treated specially:

  -all-static       do not do any dynamic linking at all
  -avoid-version    do not add a version suffix if possible
  -bindir BINDIR    specify path to binaries directory (for systems where
                    libraries must be found in the PATH setting at runtime)
  -dlopen FILE      \`-dlpreopen' FILE if it cannot be dlopened at runtime
  -dlpreopen FILE   link in FILE and add its symbols to lt_preloaded_symbols
  -export-dynamic   allow symbols from OUTPUT-FILE to be resolved with dlsym(3)
  -export-symbols SYMFILE
                    try to export only the symbols listed in SYMFILE
  -export-symbols-regex REGEX
                    try to export only the symbols matching REGEX
  -LLIBDIR          search LIBDIR for required installed libraries
  -lNAME            OUTPUT-FILE requires the installed library libNAME
  -module           build a library that can dlopened
  -no-fast-install  disable the fast-install mode
  -no-install       link a not-installable executable
  -no-undefined     declare that a library does not refer to external symbols
  -o OUTPUT-FILE    create OUTPUT-FILE from the specified objects
  -objectlist FILE  Use a list of object files found in FILE to specify objects
  -precious-files-regex REGEX
                    don't remove output files matching REGEX
  -release RELEASE  specify package release information
  -rpath LIBDIR     the created library will eventually be installed in LIBDIR
  -R[ ]LIBDIR       add LIBDIR to the runtime path of programs and libraries
  -shared           only do dynamic linking of libtool libraries
  -shrext SUFFIX    override the standard shared library file extension
  -static           do not do any dynamic linking of uninstalled libtool libraries
  -static-libtool-libs
                    do not do any dynamic linking of libtool libraries
  -version-info CURRENT[:REVISION[:AGE]]
                    specify library version info [each variable defaults to 0]
  -weak LIBNAME     declare that the target provides the LIBNAME interface
  -Wc,FLAG
  -Xcompiler FLAG   pass linker-specific FLAG directly to the compiler
  -Wl,FLAG
  -Xlinker FLAG     pass linker-specific FLAG directly to the linker
  -XCClinker FLAG   pass link-specific FLAG to the compiler driver (CC)

All other options (arguments beginning with \`-') are ignored.

Every other argument is treated as a filename.  Files ending in \`.la' are
treated as uninstalled libtool libraries, other files are standard or library
object files.

If the OUTPUT-FILE ends in \`.la', then a libtool library is created,
only library objects (\`.lo' files) may be specified, and \`-rpath' is
required, except when creating a convenience library.

If OUTPUT-FILE ends in \`.a' or \`.lib', then a standard library is created
using \`ar' and \`ranlib', or on Windows using \`lib'.

If OUTPUT-FILE ends in \`.lo' or \`.${objext}', then a reloadable object file
is created, otherwise an executable program is created."

# The TAGs below are defined such that we never get into a situation

# the user asked for that or because the platform doesn't support
# them.  This is particularly important on AIX, because we don't
# support having both static and shared libraries enabled at the same
# time on that platform, so we default to a shared-only configuration.
# If a disable-shared tag is given, we'll fallback to a static-only
# configuration.  But we'll never go from static-only to shared-only.

# For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
# $ac_aux_dir to `$srcdir/foo'.  In other projects, it is set to
# `$srcdir', `$srcdir/..', or `$srcdir/../..'.
#
# Of course, Automake must honor this variable whenever it calls a
# tool from the auxiliary directory.  The problem is that $srcdir (and
# therefore $ac_aux_dir as well) can be either absolute or relative,
# depending on how configure is run.  This is pretty annoying, since
# it makes $ac_aux_dir quite unusable in subdirectories: in the top
# source directory, any form will work fine, but in subdirectories a
# relative path needs to be adjusted first.
#
# $ac_aux_dir/missing
#    fails when called from a subdirectory if $ac_aux_dir is relative
# $top_srcdir/$ac_aux_dir/missing
#    fails if $ac_aux_dir is absolute,
#    fails when called from a subdirectory in a VPATH build with
#          a relative $ac_aux_dir
#
# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
# are both prefixed by $srcdir.  In an in-source build this is usually
# harmless because $srcdir is `.', but things will broke when you
# start a VPATH build or use an absolute $srcdir.
#
# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
# iff we strip the leading $srcdir from $ac_aux_dir.  That would be:
#   am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
# and then we would define $MISSING as
#   MISSING="\${SHELL} $am_aux_dir/missing"
# This will work as long as MISSING is not called from configure, because
# unfortunately $(top_srcdir) has no meaning in configure.
# However there are other variables, like CC, which are often used in
# configure, and could therefore not use this "fixed" $ac_aux_dir.
#
# Another solution, used here, is to always expand $ac_aux_dir to an
# absolute PATH.  The drawback is that using absolute paths prevent a
# configured tree to be moved without reconfiguration.

.SH NAME
sntp \- standard Simple Network Time Protocol program
.SH SYNOPSIS
.B sntp
.\" Mixture of short (flag) options and long options
.RB [ \-\fIflag\fP " [\fIvalue\fP]]... [" \--\fIopt-name\fP " [[=| ]\fIvalue\fP]]..."
.br

[ hostname-or-IP ...]
.PP

.SH "DESCRIPTION"
This manual page briefly documents the \fBsntp\fP command.
.I sntp
can be used as a SNTP client to query a NTP or SNTP server and either display
the time or set the local system's time (given suitable privilege).  It can be
run as an interactive command or in a
.I cron
job.

NTP (the Network Time Protocol) and SNTP (the Simple Network Time Protocol)
are defined and described by RFC 5905.

.PP
The default is to write the estimated correct local date and time (i.e. not
UTC) to the standard output in a format like
.BR "'1996-10-15 20:17:25.123 (+0800) +4.567 +/- 0.089 secs'" ,
where the
.B "'(+0800)'"
means that to get to UTC from the reported local time one must
add 8 hours and 0 minutes,
and the
.B "'+4.567 +/- 0.089 secs'"
indicates the local clock is 4.567 seconds behind the correct time
(so 4.567 seconds must be added to the local clock to get it to be correct),
and the time of
'1996-10-15 20:17:25.123'
is believed to be correct to within
+/- 0.089
seconds.
.SH OPTIONS
.TP
.BR \-4 ", " \--ipv4
Force IPv4 DNS name resolution.
This option must not appear in combination with any of the following options:

.sp
Diagnostic messages for non-fatal errors and a limited amount of
tracing should be written to standard error.  Fatal ones always
produce a diagnostic.  This option should be set when there is a
suspected problem with the server, network or the source.
.TP
.BR \-K " \fIfile-name\fP, " \--kod "=" \fIfile-name\fP
KoD history filename.
.sp

responses received from servers.  The default is
/var/db/ntp-kod.
.TP
.BR \-p ", " \--syslog
Logging with syslog.
This option must not appear in combination with any of the following options:
logfile.
.sp
When this option is set all logging will be done using syslog.
.TP
.BR \-l " \fIfile-name\fP, " \--logfile "=" \fIfile-name\fP
Log to specified logfile.
This option must not appear in combination with any of the following options:
syslog.
.sp
This option causes the client to write log messages to the specified
logfile.
.TP
.BR \-s ", " \--settod
Set (step) the time with settimeofday().
This option must not appear in combination with any of the following options:
adjtime.
.sp

.TP
.BR \-j ", " \--adjtime
Set (slew) the time with adjtime().
This option must not appear in combination with any of the following options:
settod.
.sp

.TP
.BR \-b " \fIbroadcast-address\fP, " \--broadcast "=" \fIbroadcast-address\fP
Use broadcasts to the address specified for synchronisation.
.sp
If specified SNTP will listen to the specified broadcast address
for NTP broadcasts.  The default maximum wait time,
68 seconds, can be modified with \-t.
.TP
.BR \-t " \fIseconds\fP, " \--timeout "=" \fIseconds\fP
Specify the number of seconds to wait for broadcasts.
This option takes an integer number as its argument.
The default \fIseconds\fP for this option is:
.ti +4
 68
.sp
When waiting for a broadcast packet SNTP will wait the number
of seconds specified before giving up.  Default 68 seconds.
.TP
.BR \-a " \fIauth-keynumber\fP, " \--authentication "=" \fIauth-keynumber\fP
Enable authentication with the key auth-keynumber.
This option takes an integer number as its argument.
.sp
This option enables authentication using the key specified in this option's argument.
The argument of this option is the keyid, a number specified in the keyfile as this
key's identifier. See the keyfile option (-k) for more details.
.TP
.BR \-k " \fIfile-name\fP, " \--keyfile "=" \fIfile-name\fP
Specify a keyfile. SNTP will look in this file for the key specified with \-a.
.sp
This option specifies the keyfile. SNTP will search for the key specified with \-a keyno in this
file. Key files follow the following format:

keyid keytype key

Where	keyid is a number identifying this key
keytype is one of the follow:
S  Key in 64 Bit hexadecimal number as specified in in the DES specification.
N  Key in 64 Bit hexadecimal number as specified in the NTP standard.
A  Key in a 1-to-8 character ASCII string.
M  Key in a 1-to-8 character ASCII string using the MD5 authentication scheme.

For more information see ntp.keys(5).
.TP
.BR \-? , " \--help"
Display extended usage information and exit.
.TP
.BR \-! , " \--more-help"
Extended usage information passed thru pager.
.TP
.BR \-> " [\fIrcfile\fP]," " \--save-opts" "[=\fIrcfile\fP]"
Save the option state to \fIrcfile\fP.  The default is the \fIlast\fP
configuration file listed in the \fBOPTION PRESETS\fP section, below.
.TP
.BR \-< " \fIrcfile\fP," " \--load-opts" "=\fIrcfile\fP," " \--no-load-opts"
Load options from \fIrcfile\fP.
The \fIno-load-opts\fP form will disable the loading
of earlier RC/INI files.  \fI--no-load-opts\fP is handled early,
out of order.
.TP
.BR \- " [{\fIv|c|n\fP}]," " \--version" "[=\fI{v|c|n}\fP]"
Output version of program and exit.  The default mode is `v', a simple
version.  The `c' mode will print copyright information and `n' will
print the full copyright notice.
.SH OPTION PRESETS
Any option that is not marked as \fInot presettable\fP may be preset
by loading values from configuration ("RC" or ".INI") file(s) and values from
environment variables named:
.nf
  \fBSNTP_\fP or \fBSNTP\fP
.fi
.ad
The environmental presets take precedence (are processed later than)
the configuration files.
The \fIhomerc\fP files are "\fI$HOME\fP", and "\fI.\fP".
If any of these are directories, then the file \fI.ntprc\fP
is searched for within those directories.
.SH USAGE
The simplest use of this program is as an unprivileged command to check the
current time and error in the local clock.  For example:
.IP
.B sntp ntpserver.somewhere
.PP
With suitable privilege, it can be run as a command or in a
.I cron
job to reset the local clock from a reliable server, like the
.I ntpdate
and
.I rdate
commands.  For example:
.IP
.B sntp \-a ntpserver.somewhere
.SH RETURN VALUE
The program returns a zero exit
status for success, and a non-zero one otherwise.

.SH USAGE
The simplest use of this program is as an unprivileged command to check the
current time and error in the local clock.  For example:
.IP
.B sntp ntpserver.somewhere
.PP
With suitable privilege, it can be run as a command or in a
.I cron
job to reset the local clock from a reliable server, like the
.I ntpdate
and
.I rdate
commands.  For example:
.IP
.B sntp -a ntpserver.somewhere
.SH RETURN VALUE
The program returns a zero exit
status for success, and a non-zero one otherwise.
.SH BUGS
Please report bugs to http://bugs.ntp.org .

                       Version 3, 29 June 2007

 Copyright (c) 1992-2011 by Bruce Korb - all rights reserved
 Everyone is permitted to copy and distribute verbatim copies
 of this license document, but changing it is not allowed.

                            Preamble

  The GNU General Public License is a free, copyleft license for
software and other kinds of works.

  The licenses for most software and other practical works are designed
to take away your freedom to share and change the works.  By contrast,
the GNU General Public License is intended to guarantee your freedom to
share and change all versions of a program--to make sure it remains free
software for all its users.  We, the Free Software Foundation, use the
GNU General Public License for most of our software; it applies also to
any other work released this way by its authors.  You can apply it to
your programs, too.

  When we speak of free software, we are referring to freedom, not
price.  Our General Public Licenses are designed to make sure that you
have the freedom to distribute copies of free software (and charge for
them if you wish), that you receive source code or can get it if you
want it, that you can change the software or use pieces of it in new
free programs, and that you know you can do these things.

  To protect your rights, we need to prevent others from denying you
these rights or asking you to surrender the rights.  Therefore, you have
certain responsibilities if you distribute copies of the software, or if
you modify it: responsibilities to respect the freedom of others.

  For example, if you distribute copies of such a program, whether
gratis or for a fee, you must pass on to the recipients the same
freedoms that you received.  You must make sure that they, too, receive
or can get the source code.  And you must show them these terms so they
know their rights.

  Developers that use the GNU GPL protect your rights with two steps:
(1) assert copyright on the software, and (2) offer you this License
giving you legal permission to copy, distribute and/or modify it.

  For the developers' and authors' protection, the GPL clearly explains
that there is no warranty for this free software.  For both users' and
authors' sake, the GPL requires that modified versions be marked as
changed, so that their problems will not be attributed erroneously to
authors of previous versions.

  Some devices are designed to deny users access to install or run
modified versions of the software inside them, although the manufacturer
can do so.  This is fundamentally incompatible with the aim of
protecting users' freedom to change the software.  The systematic
pattern of such abuse occurs in the area of products for individuals to
use, which is precisely where it is most unacceptable.  Therefore, we
have designed this version of the GPL to prohibit the practice for those
products.  If such problems arise substantially in other domains, we
stand ready to extend this provision to those domains in future versions
of the GPL, as needed to protect the freedom of users.

  Finally, every program is threatened constantly by software patents.
States should not allow patents to restrict development and use of
software on general-purpose computers, but in those that do, we wish to
avoid the special danger that patents applied to a free program could
make it effectively proprietary.  To prevent this, the GPL assures that
patents cannot be used to render the program non-free.

  The precise terms and conditions for copying, distribution and
modification follow.

                       TERMS AND CONDITIONS

  0. Definitions.

  "This License" refers to version 3 of the GNU General Public License.

  "Copyright" also means copyright-like laws that apply to other kinds of
works, such as semiconductor masks.

  "The Program" refers to any copyrightable work licensed under this
License.  Each licensee is addressed as "you".  "Licensees" and
"recipients" may be individuals or organizations.

  To "modify" a work means to copy from or adapt all or part of the work
in a fashion requiring copyright permission, other than the making of an
exact copy.  The resulting work is called a "modified version" of the
earlier work or a work "based on" the earlier work.

  A "covered work" means either the unmodified Program or a work based
on the Program.

  To "propagate" a work means to do anything with it that, without
permission, would make you directly or secondarily liable for
infringement under applicable copyright law, except executing it on a
computer or modifying a private copy.  Propagation includes copying,
distribution (with or without modification), making available to the
public, and in some countries other activities as well.

  To "convey" a work means any kind of propagation that enables other
parties to make or receive copies.  Mere interaction with a user through
a computer network, with no transfer of a copy, is not conveying.

  An interactive user interface displays "Appropriate Legal Notices"
to the extent that it includes a convenient and prominently visible
feature that (1) displays an appropriate copyright notice, and (2)
tells the user that there is no warranty for the work (except to the
extent that warranties are provided), that licensees may convey the
work under this License, and how to view a copy of this License.  If
the interface presents a list of user commands or options, such as a
menu, a prominent item in the list meets this criterion.

  1. Source Code.

  The "source code" for a work means the preferred form of the work
for making modifications to it.  "Object code" means any non-source
form of a work.

  A "Standard Interface" means an interface that either is an official
standard defined by a recognized standards body, or, in the case of
interfaces specified for a particular programming language, one that
is widely used among developers working in that language.

  The "System Libraries" of an executable work include anything, other
than the work as a whole, that (a) is included in the normal form of
packaging a Major Component, but which is not part of that Major
Component, and (b) serves only to enable use of the work with that
Major Component, or to implement a Standard Interface for which an
implementation is available to the public in source code form.  A
"Major Component", in this context, means a major essential component
(kernel, window system, and so on) of the specific operating system
(if any) on which the executable work runs, or a compiler used to
produce the work, or an object code interpreter used to run it.

  The "Corresponding Source" for a work in object code form means all
the source code needed to generate, install, and (for an executable
work) run the object code and to modify the work, including scripts to
control those activities.  However, it does not include the work's
System Libraries, or general-purpose tools or generally available free
programs which are used unmodified in performing those activities but
which are not part of the work.  For example, Corresponding Source
includes interface definition files associated with source files for
the work, and the source code for shared libraries and dynamically
linked subprograms that the work is specifically designed to require,
such as by intimate data communication or control flow between those
subprograms and other parts of the work.

  The Corresponding Source need not include anything that users
can regenerate automatically from other parts of the Corresponding
Source.

  The Corresponding Source for a work in source code form is that
same work.

  2. Basic Permissions.

  All rights granted under this License are granted for the term of
copyright on the Program, and are irrevocable provided the stated
conditions are met.  This License explicitly affirms your unlimited
permission to run the unmodified Program.  The output from running a
covered work is covered by this License only if the output, given its
content, constitutes a covered work.  This License acknowledges your
rights of fair use or other equivalent, as provided by copyright law.

  You may make, run and propagate covered works that you do not
convey, without conditions so long as your license otherwise remains
in force.  You may convey covered works to others for the sole purpose
of having them make modifications exclusively for you, or provide you
with facilities for running those works, provided that you comply with
the terms of this License in conveying all material for which you do
not control copyright.  Those thus making or running the covered works
for you must do so exclusively on your behalf, under your direction
and control, on terms that prohibit them from making any copies of
your copyrighted material outside their relationship with you.

  Conveying under any other circumstances is permitted solely under
the conditions stated below.  Sublicensing is not allowed; section 10
makes it unnecessary.

  3. Protecting Users' Legal Rights From Anti-Circumvention Law.

  No covered work shall be deemed part of an effective technological
measure under any applicable law fulfilling obligations under article
11 of the WIPO copyright treaty adopted on 20 December 1996, or
similar laws prohibiting or restricting circumvention of such
measures.

  When you convey a covered work, you waive any legal power to forbid
circumvention of technological measures to the extent such circumvention
is effected by exercising rights under this License with respect to
the covered work, and you disclaim any intention to limit operation or
modification of the work as a means of enforcing, against the work's
users, your or third parties' legal rights to forbid circumvention of
technological measures.

  4. Conveying Verbatim Copies.

  You may convey verbatim copies of the Program's source code as you
receive it, in any medium, provided that you conspicuously and
appropriately publish on each copy an appropriate copyright notice;
keep intact all notices stating that this License and any
non-permissive terms added in accord with section 7 apply to the code;
keep intact all notices of the absence of any warranty; and give all
recipients a copy of this License along with the Program.

  You may charge any price or no price for each copy that you convey,
and you may offer support or warranty protection for a fee.

  5. Conveying Modified Source Versions.

  You may convey a work based on the Program, or the modifications to
produce it from the Program, in the form of source code under the
terms of section 4, provided that you also meet all of these conditions:

    a) The work must carry prominent notices stating that you modified
    it, and giving a relevant date.

    b) The work must carry prominent notices stating that it is
    released under this License and any conditions added under section
    7.  This requirement modifies the requirement in section 4 to
    "keep intact all notices".

    c) You must license the entire work, as a whole, under this
    License to anyone who comes into possession of a copy.  This
    License will therefore apply, along with any applicable section 7
    additional terms, to the whole of the work, and all its parts,
    regardless of how they are packaged.  This License gives no
    permission to license the work in any other way, but it does not
    invalidate such permission if you have separately received it.

    d) If the work has interactive user interfaces, each must display
    Appropriate Legal Notices; however, if the Program has interactive
    interfaces that do not display Appropriate Legal Notices, your
    work need not make them do so.

  A compilation of a covered work with other separate and independent
works, which are not by their nature extensions of the covered work,
and which are not combined with it such as to form a larger program,
in or on a volume of a storage or distribution medium, is called an
"aggregate" if the compilation and its resulting copyright are not
used to limit the access or legal rights of the compilation's users
beyond what the individual works permit.  Inclusion of a covered work
in an aggregate does not cause this License to apply to the other
parts of the aggregate.

  6. Conveying Non-Source Forms.

  You may convey a covered work in object code form under the terms
of sections 4 and 5, provided that you also convey the
machine-readable Corresponding Source under the terms of this License,
in one of these ways:

    a) Convey the object code in, or embodied in, a physical product
    (including a physical distribution medium), accompanied by the
    Corresponding Source fixed on a durable physical medium
    customarily used for software interchange.

    b) Convey the object code in, or embodied in, a physical product
    (including a physical distribution medium), accompanied by a
    written offer, valid for at least three years and valid for as
    long as you offer spare parts or customer support for that product
    model, to give anyone who possesses the object code either (1) a
    copy of the Corresponding Source for all the software in the
    product that is covered by this License, on a durable physical
    medium customarily used for software interchange, for a price no
    more than your reasonable cost of physically performing this
    conveying of source, or (2) access to copy the
    Corresponding Source from a network server at no charge.

    c) Convey individual copies of the object code with a copy of the
    written offer to provide the Corresponding Source.  This
    alternative is allowed only occasionally and noncommercially, and
    only if you received the object code with such an offer, in accord
    with subsection 6b.

    d) Convey the object code by offering access from a designated
    place (gratis or for a charge), and offer equivalent access to the
    Corresponding Source in the same way through the same place at no
    further charge.  You need not require recipients to copy the
    Corresponding Source along with the object code.  If the place to
    copy the object code is a network server, the Corresponding Source
    may be on a different server (operated by you or a third party)
    that supports equivalent copying facilities, provided you maintain
    clear directions next to the object code saying where to find the
    Corresponding Source.  Regardless of what server hosts the
    Corresponding Source, you remain obligated to ensure that it is
    available for as long as needed to satisfy these requirements.

    e) Convey the object code using peer-to-peer transmission, provided
    you inform other peers where the object code and Corresponding
    Source of the work are being offered to the general public at no
    charge under subsection 6d.

  A separable portion of the object code, whose source code is excluded
from the Corresponding Source as a System Library, need not be
included in conveying the object code work.

  A "User Product" is either (1) a "consumer product", which means any
tangible personal property which is normally used for personal, family,
or household purposes, or (2) anything designed or sold for incorporation
into a dwelling.  In determining whether a product is a consumer product,
doubtful cases shall be resolved in favor of coverage.  For a particular
product received by a particular user, "normally used" refers to a
typical or common use of that class of product, regardless of the status
of the particular user or of the way in which the particular user
actually uses, or expects or is expected to use, the product.  A product
is a consumer product regardless of whether the product has substantial
commercial, industrial or non-consumer uses, unless such uses represent
the only significant mode of use of the product.

  "Installation Information" for a User Product means any methods,
procedures, authorization keys, or other information required to install
and execute modified versions of a covered work in that User Product from
a modified version of its Corresponding Source.  The information must
suffice to ensure that the continued functioning of the modified object
code is in no case prevented or interfered with solely because
modification has been made.

  If you convey an object code work under this section in, or with, or
specifically for use in, a User Product, and the conveying occurs as
part of a transaction in which the right of possession and use of the
User Product is transferred to the recipient in perpetuity or for a
fixed term (regardless of how the transaction is characterized), the
Corresponding Source conveyed under this section must be accompanied
by the Installation Information.  But this requirement does not apply
if neither you nor any third party retains the ability to install
modified object code on the User Product (for example, the work has
been installed in ROM).

  The requirement to provide Installation Information does not include a
requirement to continue to provide support service, warranty, or updates
for a work that has been modified or installed by the recipient, or for
the User Product in which it has been modified or installed.  Access to a
network may be denied when the modification itself materially and
adversely affects the operation of the network or violates the rules and
protocols for communication across the network.

  Corresponding Source conveyed, and Installation Information provided,
in accord with this section must be in a format that is publicly
documented (and with an implementation available to the public in
source code form), and must require no special password or key for
unpacking, reading or copying.

  7. Additional Terms.

  "Additional permissions" are terms that supplement the terms of this
License by making exceptions from one or more of its conditions.
Additional permissions that are applicable to the entire Program shall
be treated as though they were included in this License, to the extent
that they are valid under applicable law.  If additional permissions
apply only to part of the Program, that part may be used separately
under those permissions, but the entire Program remains governed by
this License without regard to the additional permissions.

  When you convey a copy of a covered work, you may at your option
remove any additional permissions from that copy, or from any part of
it.  (Additional permissions may be written to require their own
removal in certain cases when you modify the work.)  You may place
additional permissions on material, added by you to a covered work,
for which you have or can give appropriate copyright permission.

  Notwithstanding any other provision of this License, for material you
add to a covered work, you may (if authorized by the copyright holders of
that material) supplement the terms of this License with terms:

    a) Disclaiming warranty or limiting liability differently from the
    terms of sections 15 and 16 of this License; or

    b) Requiring preservation of specified reasonable legal notices or
    author attributions in that material or in the Appropriate Legal
    Notices displayed by works containing it; or

    c) Prohibiting misrepresentation of the origin of that material, or
    requiring that modified versions of such material be marked in
    reasonable ways as different from the original version; or

    d) Limiting the use for publicity purposes of names of licensors or
    authors of the material; or

    e) Declining to grant rights under trademark law for use of some
    trade names, trademarks, or service marks; or

    f) Requiring indemnification of licensors and authors of that
    material by anyone who conveys the material (or modified versions of
    it) with contractual assumptions of liability to the recipient, for
    any liability that these contractual assumptions directly impose on
    those licensors and authors.

  All other non-permissive additional terms are considered "further
restrictions" within the meaning of section 10.  If the Program as you
received it, or any part of it, contains a notice stating that it is
governed by this License along with a term that is a further
restriction, you may remove that term.  If a license document contains
a further restriction but permits relicensing or conveying under this
License, you may add to a covered work material governed by the terms
of that license document, provided that the further restriction does
not survive such relicensing or conveying.

  If you add terms to a covered work in accord with this section, you
must place, in the relevant source files, a statement of the
additional terms that apply to those files, or a notice indicating
where to find the applicable terms.

  Additional terms, permissive or non-permissive, may be stated in the
form of a separately written license, or stated as exceptions;
the above requirements apply either way.

  8. Termination.

  You may not propagate or modify a covered work except as expressly
provided under this License.  Any attempt otherwise to propagate or
modify it is void, and will automatically terminate your rights under
this License (including any patent licenses granted under the third
paragraph of section 11).

  However, if you cease all violation of this License, then your
license from a particular copyright holder is reinstated (a)
provisionally, unless and until the copyright holder explicitly and
finally terminates your license, and (b) permanently, if the copyright
holder fails to notify you of the violation by some reasonable means
prior to 60 days after the cessation.

  Moreover, your license from a particular copyright holder is
reinstated permanently if the copyright holder notifies you of the
violation by some reasonable means, this is the first time you have
received notice of violation of this License (for any work) from that
copyright holder, and you cure the violation prior to 30 days after
your receipt of the notice.

  Termination of your rights under this section does not terminate the
licenses of parties who have received copies or rights from you under
this License.  If your rights have been terminated and not permanently
reinstated, you do not qualify to receive new licenses for the same
material under section 10.

  9. Acceptance Not Required for Having Copies.

  You are not required to accept this License in order to receive or
run a copy of the Program.  Ancillary propagation of a covered work
occurring solely as a consequence of using peer-to-peer transmission
to receive a copy likewise does not require acceptance.  However,
nothing other than this License grants you permission to propagate or
modify any covered work.  These actions infringe copyright if you do
not accept this License.  Therefore, by modifying or propagating a
covered work, you indicate your acceptance of this License to do so.

  10. Automatic Licensing of Downstream Recipients.

  Each time you convey a covered work, the recipient automatically
receives a license from the original licensors, to run, modify and
propagate that work, subject to this License.  You are not responsible
for enforcing compliance by third parties with this License.

  An "entity transaction" is a transaction transferring control of an
organization, or substantially all assets of one, or subdividing an
organization, or merging organizations.  If propagation of a covered
work results from an entity transaction, each party to that
transaction who receives a copy of the work also receives whatever
licenses to the work the party's predecessor in interest had or could
give under the previous paragraph, plus a right to possession of the
Corresponding Source of the work from the predecessor in interest, if
the predecessor has it or can get it with reasonable efforts.

  You may not impose any further restrictions on the exercise of the
rights granted or affirmed under this License.  For example, you may
not impose a license fee, royalty, or other charge for exercise of
rights granted under this License, and you may not initiate litigation
(including a cross-claim or counterclaim in a lawsuit) alleging that
any patent claim is infringed by making, using, selling, offering for
sale, or importing the Program or any portion of it.

  11. Patents.

  A "contributor" is a copyright holder who authorizes use under this
License of the Program or a work on which the Program is based.  The
work thus licensed is called the contributor's "contributor version".

  A contributor's "essential patent claims" are all patent claims
owned or controlled by the contributor, whether already acquired or
hereafter acquired, that would be infringed by some manner, permitted
by this License, of making, using, or selling its contributor version,
but do not include claims that would be infringed only as a
consequence of further modification of the contributor version.  For
purposes of this definition, "control" includes the right to grant
patent sublicenses in a manner consistent with the requirements of
this License.

  Each contributor grants you a non-exclusive, worldwide, royalty-free
patent license under the contributor's essential patent claims, to
make, use, sell, offer for sale, import and otherwise run, modify and
propagate the contents of its contributor version.

  In the following three paragraphs, a "patent license" is any express
agreement or commitment, however denominated, not to enforce a patent
(such as an express permission to practice a patent or covenant not to
sue for patent infringement).  To "grant" such a patent license to a
party means to make such an agreement or commitment not to enforce a
patent against the party.

  If you convey a covered work, knowingly relying on a patent license,
and the Corresponding Source of the work is not available for anyone
to copy, free of charge and under the terms of this License, through a
publicly available network server or other readily accessible means,
then you must either (1) cause the Corresponding Source to be so
available, or (2) arrange to deprive yourself of the benefit of the
patent license for this particular work, or (3) arrange, in a manner
consistent with the requirements of this License, to extend the patent
license to downstream recipients.  "Knowingly relying" means you have
actual knowledge that, but for the patent license, your conveying the
covered work in a country, or your recipient's use of the covered work
in a country, would infringe one or more identifiable patents in that
country that you have reason to believe are valid.

  If, pursuant to or in connection with a single transaction or
arrangement, you convey, or propagate by procuring conveyance of, a
covered work, and grant a patent license to some of the parties
receiving the covered work authorizing them to use, propagate, modify
or convey a specific copy of the covered work, then the patent license
you grant is automatically extended to all recipients of the covered
work and works based on it.

  A patent license is "discriminatory" if it does not include within
the scope of its coverage, prohibits the exercise of, or is
conditioned on the non-exercise of one or more of the rights that are
specifically granted under this License.  You may not convey a covered
work if you are a party to an arrangement with a third party that is
in the business of distributing software, under which you make payment
to the third party based on the extent of your activity of conveying
the work, and under which the third party grants, to any of the
parties who would receive the covered work from you, a discriminatory
patent license (a) in connection with copies of the covered work
conveyed by you (or copies made from those copies), or (b) primarily
for and in connection with specific products or compilations that
contain the covered work, unless you entered into that arrangement,
or that patent license was granted, prior to 28 March 2007.

  Nothing in this License shall be construed as excluding or limiting
any implied license or other defenses to infringement that may
otherwise be available to you under applicable patent law.

  12. No Surrender of Others' Freedom.

  If conditions are imposed on you (whether by court order, agreement or
otherwise) that contradict the conditions of this License, they do not
excuse you from the conditions of this License.  If you cannot convey a
covered work so as to satisfy simultaneously your obligations under this
License and any other pertinent obligations, then as a consequence you may
not convey it at all.  For example, if you agree to terms that obligate you
to collect a royalty for further conveying from those to whom you convey
the Program, the only way you could satisfy both those terms and this
License would be to refrain entirely from conveying the Program.

  13. Use with the GNU Affero General Public License.

  Notwithstanding any other provision of this License, you have
permission to link or combine any covered work with a work licensed
under version 3 of the GNU Affero General Public License into a single
combined work, and to convey the resulting work.  The terms of this
License will continue to apply to the part which is the covered work,
but the special requirements of the GNU Affero General Public License,
section 13, concerning interaction through a network will apply to the
combination as such.

  14. Revised Versions of this License.

  The Free Software Foundation may publish revised and/or new versions of
the GNU General Public License from time to time.  Such new versions will
be similar in spirit to the present version, but may differ in detail to
address new problems or concerns.

  Each version is given a distinguishing version number.  If the
Program specifies that a certain numbered version of the GNU General
Public License "or any later version" applies to it, you have the
option of following the terms and conditions either of that numbered
version or of any later version published by the Free Software
Foundation.  If the Program does not specify a version number of the
GNU General Public License, you may choose any version ever published
by the Free Software Foundation.

  If the Program specifies that a proxy can decide which future
versions of the GNU General Public License can be used, that proxy's
public statement of acceptance of a version permanently authorizes you
to choose that version for the Program.

  Later license versions may give you additional or different
permissions.  However, no additional obligations are imposed on any
author or copyright holder as a result of your choosing to follow a
later version.

  15. Disclaimer of Warranty.

  THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
APPLICABLE LAW.  EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
IS WITH YOU.  SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
ALL NECESSARY SERVICING, REPAIR OR CORRECTION.

  16. Limitation of Liability.

  IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
SUCH DAMAGES.

  17. Interpretation of Sections 15 and 16.

  If the disclaimer of warranty and limitation of liability provided
above cannot be given local legal effect according to their terms,
reviewing courts shall apply local law that most closely approximates
an absolute waiver of all civil liability in connection with the
Program, unless a warranty or assumption of liability accompanies a
copy of the Program in return for a fee.

                     END OF TERMS AND CONDITIONS

            How to Apply These Terms to Your New Programs

  If you develop a new program, and you want it to be of the greatest
possible use to the public, the best way to achieve this is to make it
free software which everyone can redistribute and change under these terms.

  To do so, attach the following notices to the program.  It is safest
to attach them to the start of each source file to most effectively
state the exclusion of warranty; and each file should have at least
the "copyright" line and a pointer to where the full notice is found.

    
    copyright (c) by Bruce Korb - all rights reserved

    This program is free software: you can redistribute it and/or modify
    it under the terms of the GNU General Public License as published by
    the Free Software Foundation, either version 3 of the License, or
    (at your option) any later version.

    This program is distributed in the hope that it will be useful,
    but WITHOUT ANY WARRANTY; without even the implied warranty of
    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
    GNU General Public License for more details.

    You should have received a copy of the GNU General Public License
    along with this program.  If not, see .

Also add information on how to contact you by electronic and paper mail.

  If the program does terminal interaction, make it output a short
notice like this when it starts in an interactive mode:

      copyright (c)  by Bruce Korb - all rights reserved
    This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
    This is free software, and you are welcome to redistribute it
    under certain conditions; type `show c' for details.

The hypothetical commands `show w' and `show c' should show the appropriate
parts of the General Public License.  Of course, your program's commands
might be different; for a GUI interface, you would use an "about box".

  You should also get your employer (if you work as a programmer) or school,
if any, to sign a "copyright disclaimer" for the program, if necessary.
For more information on this, and how to apply and follow the GNU GPL, see
.

  The GNU General Public License does not permit incorporating your program
into proprietary programs.  If your program is a subroutine library, you
may consider it more useful to permit linking proprietary applications with
the library.  If this is what you want to do, use the GNU Lesser General
Public License instead of this License.  But first, please read

 *
 * ret_type:  char*
 * ret_desc:  the path to the located file
 *
 * doc:
 *
 * pathfind looks for a a file with name "FILE" and "MODE" access
 * along colon delimited "PATH", and returns the full pathname as a
 * string, or NULL if not found.  If "FILE" contains a slash, then
 * it is treated as a relative or absolute path and "PATH" is ignored.
 *
 * @strong{NOTE}: this function is compiled into @file{libopts} only if
 * it is not natively supplied.
 *
 * The "MODE" argument is a string of option letters chosen from the
 * list below:
 * @example
 *          Letter    Meaning
 *          r         readable
 *          w         writable
 *          x         executable

 *          c         character special (NOT IMPLEMENTED)

 *          s         size nonzero      (NOT IMPLEMENTED)
 * @end example
 *
 * example:
 * To find the "ls" command using the "PATH" environment variable:
 * @example
 *    #include 
 *    char* pz_ls = pathfind( getenv("PATH"), "ls", "rx" );
 *    <>
 *    free( pz_ls );
 * @end example
 * The path is allocated with @code{malloc(3C)}, so you must @code{free(3C)}
 * the result.  Also, do not use unimplemented file modes.  :-)
 *
 * err:  returns NULL if the file is not found.

   SYNOPSIS
       #include 

       char *strchr(char const *s, int c);

       char *strrchr(char const *s, int c);

   DESCRIPTION
       The  strchr() function returns a pointer to the first occurrence of the
       character c in the string s.

       The strrchr() function returns a pointer to the last occurrence of  the
       character c in the string s.

       Here  "character"  means "byte" - these functions do not work with wide
       or multi-byte characters.

   RETURN VALUE
       The strchr() and strrchr() functions return a pointer  to  the  matched
       character or NULL if the character is not found.

   CONFORMING TO
       SVID 3, POSIX, BSD 4.3, ISO 9899

/*

  Readers and users of this function are referred to the ISO-8601
  specification, with particular attention to "Durations".

  At the time of writing, this worked:

  http://en.wikipedia.org/wiki/ISO_8601#Durations

  The string must start with a 'P', 'T' or a digit.

  ==== if it is a digit

  the string may contain:  NNN Y NNN M NNN W NNN d NNN h NNN m NNN s
  This represents NNN years, NNN months, NNN weeks, NNN days, NNN hours,
    NNN minutes and NNN seconds.
  The embeded white space is optional.
  These terms must appear in this order.
  Case is significant:  'M' is months and 'm' is minutes.
  The final "s" is optional.
  All of the terms ("NNN" plus designator) are optional.
  Minutes and seconds may optionally be represented as NNN:NNN.
  Also, hours, minute and seconds may be represented as NNN:NNN:NNN.
  There is no limitation on the value of any of the terms, except
  that the final result must fit in a time_t value.

  ==== if it is a 'P' or 'T', please see ISO-8601 for a rigorous definition.

  The 'P' term may be followed by any of three formats:
    yyyymmdd
    yy-mm-dd
    yy Y mm M ww W dd D

  or it may be empty and followed by a 'T'.  The "yyyymmdd" must be eight
  digits long.

  NOTE!  Months are always 30 days and years are always 365 days long.
  5 years is always 1825 days, not 1826 or 1827 depending on leap year
  considerations.  3 months is always 90 days.  There is no consideration
  for how many days are in the current, next or previous months.

  For the final format:
  *  Embedded white space is allowed, but it is optional.
  *  All of the terms are optional.  Any or all-but-one may be omitted.
  *  The meanings are yy years, mm months, ww weeks and dd days.
  *  The terms must appear in this order.

  ==== The 'T' term may be followed by any of these formats:

    hhmmss
    hh:mm:ss
    hh H mm M ss S

  For the final format:
  *  Embedded white space is allowed, but it is optional.
  *  All of the terms are optional.  Any or all-but-one may be omitted.
  *  The terms must appear in this order.

The contents of this tarball is designed to be incorporated into
software packages that utilize the AutoOpts option automation package
and are intended to be installed on systems that may not have libopts
installed.  It is redistributable under the terms of either the LGPL
(see COPYING.lgpl) or under the terms of the advertising clause free BSD
license (see COPYING.mbsd).

Usage Instructions for autoconf/automake/libtoolized projects:

1. Install the unrolled tarball into your package source tree,
   copying ``libopts.m4'' to your autoconf macro directory.

   In your bootstrap (pre-configure) script, you can do this:

      rm -rf libopts libopts-*
      gunzip -c `autoopts-config libsrc` | tar -xvf -
      mv -f libopts-*.*.* libopts
      cp -fp libopts/m4/*.m4 m4/.

   I tend to put my configure auxiliary files in "m4".
   Whatever directory you choose, if it is not ".", then
   be sure to tell autoconf about it with:

      AC_CONFIG_AUX_DIR(m4)

   This is one macro where you *MUST* remember to *NOT* quote
   the argument.  If you do, automake will get lost.

2. Add an invocation of either LIBOPTS_CHECK or LIBOPTS_CHECK_NOBUILD
   to your configure.ac file.  See LIBOPTS_CHECK: below for details.

3. Add the following to your top level ``Makefile.am'' file:

      if NEED_LIBOPTS
         SUBDIRS += $(LIBOPTS_DIR)
      endif

   where ``<...>'' can be whatever other files or directories you may
   need.  The SUBDIRS must be properly ordered.  *PLEASE NOTE* it is
   crucial that the SUBDIRS be set under the control of an automake
   conditional.  To work correctly, automake has to know the range of
   possible values of SUBDIRS.  It's a magical name with magical
   properties.  ``NEED_LIBOPTS'' will be correctly set by the
   ``LIBOPTS_CHECK'' macro, above.

4. Add ``$(LIBOPTS_CFLAGS)'' to relevant compiler flags and
   ``$(LIBOPTS_LDADD)'' to relevant link options whereever
   you need them in your build tree.

5. Make sure your object files explicitly depend upon the
   generated options header file.  e.g.:

     $(prog_OBJECTS) : prog-opts.h
     prog-opts.h : prog-opts.c
     prog-opts.c : prog-opts.def
         autogen prog-opts.def

6. *OPTIONAL* --
   If you are creating man pages and texi documentation from
   the program options, you will need these rules somewhere, too:

     man_MANS = prog.1
     prog.1 : prog-opts.def
         autogen -Tagman-cmd.tpl -bprog prog-opts.def

     invoke-prog.texi : prog-opts.def
         autogen -Tagtexi-cmd.tpl prog-opts.def

If your package does not utilize the auto* tools, then you
will need to hand craft the rules for building the library.

LIBOPTS_CHECK:

The arguments to both macro are a relative path to the directory with
the libopts source code.  It is optional and defaults to "libopts".
These macros work as follows:

1.  LIBOPTS_CHECK([libopts/rel/path/optional])

    Adds two command-line options to the generated configure script,
    --enable-local-libopts and --disable-libopts-install.  AC_SUBST's
    LIBOPTS_CFLAGS, LIBOPTS_LDADD, and LIBOPTS_DIR for use in
    Makefile.am files.  Adds Automake conditional NEED_LIBOPTS which
    will be true when the local copy of libopts should be built.  Uses
    AC_CONFIG_FILES([$libopts-dir/Makefile]) to cause the local libopts
    into the package build.  If the optional relative path to libopts is
    not provided, it defaults to simply "libopts".

2.  LIBOPTS_CHECK_NOBUILD([libopts/rel/path/optional])

    This variant of LIBOPTS_CHECK is useful when multiple configure.ac
    files in a package make use of a single libopts tearoff.  In that
    case, only one of the configure.ac files should build libopts and
    others should simply use it.  Consider this package arrangment:

    all-tools/
      configure.ac
      common-tools/
        configure.ac
        libopts/

    The parent package all-tools contains a subpackage common-tools
    which can be torn off and used independently.  Programs configured
    by both configure.ac files link against the common-tools/libopts
    tearoff, when not using the system's libopts.  The top-level
    configure.ac uses LIBOPTS_CHECK_NOBUILD([common-tools/libopts]),
    while common-tools/configure.ac uses LIBOPTS_CHECK.  The difference
    is LIBOPTS_CHECK_NOBUILD will never build the libopts tearoff,
    leaving that to the subpackage configure.ac's LIBOPTS_CHECK.
    Specifically, LIBOPTS_CHECK_NOBUILD always results in the
    NEED_LIBOPTS Automake conditional being false, and does not invoke
    AC_CONFIG_FILES(path-to-libopts/Makefile).

                       Version 3, 29 June 2007

 Copyright (c) 1992-2011 by Bruce Korb - all rights reserved
 Everyone is permitted to copy and distribute verbatim copies
 of this license document, but changing it is not allowed.


  This version of the GNU Lesser General Public License incorporates
the terms and conditions of version 3 of the GNU General Public
License, supplemented by the additional permissions listed below.

  0. Additional Definitions. 

  As used herein, "this License" refers to version 3 of the GNU Lesser
General Public License, and the "GNU GPL" refers to version 3 of the GNU
General Public License.

  "The Library" refers to a covered work governed by this License,
other than an Application or a Combined Work as defined below.

  An "Application" is any work that makes use of an interface provided
by the Library, but which is not otherwise based on the Library.
Defining a subclass of a class defined by the Library is deemed a mode
of using an interface provided by the Library.

  A "Combined Work" is a work produced by combining or linking an
Application with the Library.  The particular version of the Library
with which the Combined Work was made is also called the "Linked
Version".

  The "Minimal Corresponding Source" for a Combined Work means the
Corresponding Source for the Combined Work, excluding any source code
for portions of the Combined Work that, considered in isolation, are
based on the Application, and not on the Linked Version.

  The "Corresponding Application Code" for a Combined Work means the
object code and/or source code for the Application, including any data
and utility programs needed for reproducing the Combined Work from the
Application, but excluding the System Libraries of the Combined Work.

  1. Exception to Section 3 of the GNU GPL.

  You may convey a covered work under sections 3 and 4 of this License
without being bound by section 3 of the GNU GPL.

  2. Conveying Modified Versions.

  If you modify a copy of the Library, and, in your modifications, a
facility refers to a function or data to be supplied by an Application
that uses the facility (other than as an argument passed when the
facility is invoked), then you may convey a copy of the modified
version:

   a) under this License, provided that you make a good faith effort to
   ensure that, in the event an Application does not supply the
   function or data, the facility still operates, and performs
   whatever part of its purpose remains meaningful, or

   b) under the GNU GPL, with none of the additional permissions of
   this License applicable to that copy.

  3. Object Code Incorporating Material from Library Header Files.

  The object code form of an Application may incorporate material from
a header file that is part of the Library.  You may convey such object
code under terms of your choice, provided that, if the incorporated
material is not limited to numerical parameters, data structure
layouts and accessors, or small macros, inline functions and templates
(ten or fewer lines in length), you do both of the following:

   a) Give prominent notice with each copy of the object code that the
   Library is used in it and that the Library and its use are
   covered by this License.

   b) Accompany the object code with a copy of the GNU GPL and this license
   document.

  4. Combined Works.

  You may convey a Combined Work under terms of your choice that,
taken together, effectively do not restrict modification of the
portions of the Library contained in the Combined Work and reverse
engineering for debugging such modifications, if you also do each of
the following:

   a) Give prominent notice with each copy of the Combined Work that
   the Library is used in it and that the Library and its use are
   covered by this License.

   b) Accompany the Combined Work with a copy of the GNU GPL and this license
   document.

   c) For a Combined Work that displays copyright notices during
   execution, include the copyright notice for the Library among
   these notices, as well as a reference directing the user to the
   copies of the GNU GPL and this license document.

   d) Do one of the following:

       0) Convey the Minimal Corresponding Source under the terms of this
       License, and the Corresponding Application Code in a form
       suitable for, and under terms that permit, the user to
       recombine or relink the Application with a modified version of
       the Linked Version to produce a modified Combined Work, in the
       manner specified by section 6 of the GNU GPL for conveying
       Corresponding Source.

       1) Use a suitable shared library mechanism for linking with the
       Library.  A suitable mechanism is one that (a) uses at run time
       a copy of the Library already present on the user's computer
       system, and (b) will operate properly with a modified version
       of the Library that is interface-compatible with the Linked
       Version. 

   e) Provide Installation Information, but only if you would otherwise
   be required to provide such information under section 6 of the
   GNU GPL, and only to the extent that such information is
   necessary to install and execute a modified version of the
   Combined Work produced by recombining or relinking the
   Application with a modified version of the Linked Version. (If
   you use option 4d0, the Installation Information must accompany
   the Minimal Corresponding Source and Corresponding Application
   Code. If you use option 4d1, you must provide the Installation
   Information in the manner specified by section 6 of the GNU GPL
   for conveying Corresponding Source.)

  5. Combined Libraries.

  You may place library facilities that are a work based on the
Library side by side in a single library together with other library
facilities that are not Applications and are not covered by this
License, and convey such a combined library under terms of your
choice, if you do both of the following:

   a) Accompany the combined library with a copy of the same work based
   on the Library, uncombined with any other library facilities,
   conveyed under the terms of this License.

   b) Give prominent notice with the combined library that part of it
   is a work based on the Library, and explaining where to find the
   accompanying uncombined form of the same work.

  6. Revised Versions of the GNU Lesser General Public License.

  The Free Software Foundation may publish revised and/or new versions
of the GNU Lesser General Public License from time to time. Such new
versions will be similar in spirit to the present version, but may
differ in detail to address new problems or concerns.

  Each version is given a distinguishing version number. If the
Library as you received it specifies that a certain numbered version
of the GNU Lesser General Public License "or any later version"
applies to it, you have the option of following the terms and
conditions either of that published version or of any later version
published by the Free Software Foundation. If the Library as you
received it does not specify a version number of the GNU Lesser
General Public License, you may choose any version of the GNU Lesser
General Public License ever published by the Free Software Foundation.

  If the Library as you received it specifies that a proxy can decide
whether future versions of the GNU Lesser General Public License shall
apply, that proxy's public statement of acceptance of any version is
permanent authorization for you to choose that version for the
Library.

 * what: tokenize an input string
 *
 * arg:  + char const* + string + string to be tokenized +
 *
 * ret_type:  token_list_t*
 * ret_desc:  pointer to a structure that lists each token
 *
 * doc:
 *
 * This function will convert one input string into a list of strings.
 * The list of strings is derived by separating the input based on
 * white space separation.  However, if the input contains either single
 * or double quote characters, then the text after that character up to
 * a matching quote will become the string in the list.
 *
 *  The returned pointer should be deallocated with @code{free(3C)} when
 *  are done using the data.  The data are placed in a single block of
 *  allocated memory.  Do not deallocate individual token/strings.
 *
 *  The structure pointed to will contain at least these two fields:
 *  @table @samp
 *  @item tkn_ct
 *  The number of tokens found in the input string.
 *  @item tok_list
 *  An array of @code{tkn_ct + 1} pointers to substring tokens, with
 *  the last pointer set to NULL.
 *  @end table
 *
 * There are two types of quoted strings: single quoted (@code{'}) and
 * double quoted (@code{"}).  Singly quoted strings are fairly raw in that
 * escape characters (@code{\\}) are simply another character, except when
 * preceding the following characters:
 * @example
 * @code{\\}  double backslashes reduce to one
 * @code{'}   incorporates the single quote into the string
 * @code{\n}  suppresses both the backslash and newline character
 * @end example
 *
 * Double quote strings are formed according to the rules of string
 * constants in ANSI-C programs.
 *
 * example:
 * @example
 *    #include 
 *    int ix;
 *    token_list_t* ptl = ao_string_tokenize(some_string)
 *    for (ix = 0; ix < ptl->tkn_ct; ix++)
 *       do_something_with_tkn(ptl->tkn_list[ix]);
 *    free(ptl);
 * @end example
 * Note that everything is freed with the one call to @code{free(3C)}.
 *
 * err:
 *  NULL is returned and @code{errno} will be set to indicate the problem:
 *  @itemize @bullet
 *  @item
 *  @code{EINVAL} - There was an unterminated quoted string.
 *  @item
 *  @code{ENOENT} - The input string was empty.
 *  @item
 *  @code{ENOMEM} - There is not enough memory.
 *  @end itemize

 *  PUBLIC DEFINES
 *
 *  The following defines may be used in applications that need to test the
 *  state of an option.  To test against these masks and values, a pointer
 *  to an option descriptor must be obtained.  There are two ways:
 *
 *  1. inside an option processing procedure, it is the second argument,
 *     conventionally "tOptDesc* pOD".
 *
 *  2. Outside of an option procedure (or to reference a different option
 *     descriptor), use either "&DESC( opt_name )" or "&pfx_DESC( opt_name )".
 *
 *  See the relevant generated header file to determine which and what
 *  values for "opt_name" are available.

 *
 *  This function will convert one input string into a list of strings.

 *  The number of tokens found in the input string.
 *  @item tok_list
 *  An array of @code{tkn_ct + 1} pointers to substring tokens, with

 *  escape characters (@code{\\}) are simply another character, except when
 *  preceding the following characters:

#
# depsver.mf	included in Makefile.am for directories with .deps
#
# When building in the same directory with sources that change over
# time, such as when tracking using bk, the .deps files can become
# stale with respect to moved, deleted, or superceded headers.  Most
# commonly, this would exhibit as make reporting a failure to make a
# header file which is no longer in the location given.  To address
# this issue, we use a deps-ver file which is updated with each change
# that breaks old .deps files.  A copy of deps-ver is made into
# $(DEPDIR) if not already present.  If $(DEPDIR)/deps-ver is present
# with different contents than deps-ver, we make clean to ensure all
# .o files built before the incompatible change are rebuilt along with
# their updated .deps files, then remove $(DEPDIR) and recreate it as
# empty stubs.
#
# It is normal when configured with --disable-dependency-tracking for
# the DEPDIR to not have been created.  For this reason, we use the
# intermediate target .deps-ver, which invokes make recursively if
# DEPDIR exists.
#
# If you modify depsver.mf, please make the changes to the master
# copy, the one in sntp is copied by the bootstrap script from it.
#
# This comment block follows rather than leads the related code so that
# it stays with it in the generated Makefile.in and Makefile.
#

# Tell versions [3.59,3.63) of GNU make to not export all variables.
# Otherwise a system limit (for SysV at least) may be exceeded.

They have not yet fully been ported to architectures other than Sun with
SunOS 4.x.  So if you want to try them you are on your own - a little
porting may be necessary.

parsetest:	simple parse streams module test
		Works only under SunOS with parse Streams Module loaded
		and Meinberg-Clocks

testdcf:	simple DCF77 raw impulse test program via 50Baud RS232

dcfd:		simple DCF77 raw impulse receiver with NTP loopfilter
		mechanics for synchronisation (allows DCF77 synchronisation
		without network code in a nutshell)

  [Bug 1325] unreachable code in sntp recv_bcst_data().
  [Bug 1459] sntp MD5 authentication does not work with ntpd.
  Many sntp fixes from Nelson Boyard:
    1. sntp properly handles hex key strings in the keyfile, instead of
    just treating the text as binary strings.
    2. sntp handles SHA1 as well as MD5.
    3. If the key file contains more than one key, sntp can use keys
    other than the first one in the file.
    4. sntp computes the MAC using the key, then the data (was other way).
    5. sntp handles responses with extensions now.
    6. sntp implements the -b (broadcast/multicast) option.  Tested.
    The -b option takes an argument which is the broadcast/multicast
    address on which to listen for packets.  The command still requires a
    host address at the end of the command line.  This is the address
    expected to do the broadcasting/multicasting.
    7. sntp correctly handles network-order key IDs on little-endian.
    8. Eliminated a huge amount of code duplication between the sntp
    unicast and multicast code paths, creating a single process_pkt()
    function that is used for both paths after the packet is received.
    9. The -t timeout option now works with both unicast and multicast.
    Previously it worked with neither.  It wasn't coded for unicast, and
    was incorrectly coded for multicast.
    10. In unicast mode, the requests are sent MACed using the key
    specified with the -a command line option.
    11. Cleaned up indentation consistent with the predominant style in
    the files changed, namely, using tab stop characters and not spaces
    for indentation.  This way, you can set your tab stop spacing as you
    like it and the indentation looks correct.  This was not a big change.
    The files were mostly consistent before.
    12. Eliminated LOTS of blank lines.
  sntp/configure.ac OpenSSL support now that sntp optionally uses it.
  Escape unprintable characters in a refid in ntpq -p billboard.

      like it and the indentation looks correct.  This was not a big change.

  sntp/networking.h@1.18 +3 -3
    [Bug 1459] sntp MD5 authentication does not work with ntpd.
    Many sntp fixes from Nelson Boyard:
      1. sntp properly handles hex key strings in the keyfile, instead of
      just treating the text as binary strings.
      2. sntp handles SHA1 as well as MD5.
      3. If the key file contains more than one key, sntp can use keys
      other than the first one in the file.
      4. sntp computes the MAC using the key, then the data (was other way).
      5. sntp handles responses with extensions now.
      6. sntp implements the -b (broadcast/multicast) option.  Tested.
      The -b option takes an argument which is the broadcast/multicast
      address on which to listen for packets.  The command still requires a
      host address at the end of the command line.  This is the address
      expected to do the broadcasting/multicasting.
      7. sntp correctly handles network-order key IDs on little-endian.
      8. Eliminated a huge amount of code duplication between the sntp
      unicast and multicast code paths, creating a single process_pkt()
      function that is used for both paths after the packet is received.
      9. The -t timeout option now works with both unicast and multicast.
      Previously it worked with neither.  It wasn't coded for unicast, and
      was incorrectly coded for multicast.
      10. In unicast mode, the requests are sent MACed using the key
      specified with the -a command line option.
      11. Cleaned up indentation consistent with the predominant style in
      the files changed, namely, using tab stop characters and not spaces
      for indentation.  This way, you can set your tab stop spacing as you
      like it and the indentation looks correct.  This was not a big change.
      The files were mostly consistent before.
      12. Eliminated LOTS of blank lines.

    add COPYRIGHT-please target for use by sntp/Makefile.am
    minor tweak to COPYRIGHT action to create intermediate file in

      interfering with each other.
    add do-nothing action for rule lacking one to avoid any use
      of SCCS get default.

  sntp/Makefile.am@1.26 +34 -5
    [Bug 1473] "make distcheck" before build can't make sntp/version.m4.
      add targets for autogen-version.def, version.def, version.m4, and
      version.texi which invoke a submake on the corresponding check-*
      targets, avoiding an explicit dependency which would cause Autogen
      to be invoked to make sntp-opts.h, which would be considered out-
      of-date because version.def is, and version,def because it depends
      on non-existent check-version.def.  The submake ensures the check
      action is taken without introducing the troublesome dependency.
    use "cd .. && $(MAKE) COPYRIGHT-please" to work around quirk with
      FreeBSD 6.x make which fails with "make COPYRIGHT" when 
      "make ./COPYRIGHT" would work.

    NTP_VPATH_HACK was misfiring on FreeBSD with recent GNU Make due to
      a change from "GNU Make version" to "GNU Make" as the gmake -v output.
    Also do not cache the result, running make -v and grep is worth it to 
      allow changing make without flushing the cache.

  Updated build and flock-build scripts.  flock-build --one is a way
    to perform a flock-build compatible solitary build, handy for a repo
    clone's first build on a machine with autoconf, automake, etc.
  Compiling ntp_parser.y using BSD make correctly places ntp_parser.h
    in the top-level ntpd directory instead of A.*/ntpd.
  bootstrap script updated to remove potentially stale .deps dirs.

    store configure cache in top srcdir config.cache-{hostname}

  flock-build@1.44 +54 -37
    add --one option to invoke a single build on the invoking
      host using flock-build's options to configure, useful to
      bring a repo clone tree to a state like a tarball, ready
      for flock-building on hosts without all dev tools (such
      as autoconf, automake, bison).
    update udel flock default LIST

    introduce vphack_after rule to fix ntp_parser.h placement when
      using build and BSD make.  Thanks for Harlan's help on this.

ChangeSet@1.2004.1.1, 2009-09-24 07:27:15+00:00, davehart@shiny.ad.hartbrothers.com
  Reorganize our copy of libisc code to match BIND 9 tarball layout, preparing
  for easier drop-in of newer libisc code in the future via a
  "ntp-dev-libisc-upstream" repo which gets only unmodified ISC source, and is
  pulled into ntp-dev allowing BK to assist with the merge of local changes in
  the future.

    [Bug 1279] Cleanup for warnings from Veracode static analysis

ChangeSet@1.1944, 2009-08-08 17:30:14+00:00, davehart@shiny.ad.hartbrothers.com
  First pass at quieting Veracode static analysis warnings,
    mostly buffer manipulation that is already safe but used
    unsafe interface functions such as strcpy() and sprintf().
  use emalloc(), estrdup() where appropriate.

  libntp/msyslog.c@1.23 +7 -6
    use memcpy instead of strcpy to quiet Veracode analysis warning

  libntp/ntp_rfc2553.c@1.39 +2 -6
    use estrdup() instead of malloc() then strcpy()

  libntp/statestr.c@1.17 +5 -4
    sprintf() -> snprintf() Veracode

  libparse/parse.c@1.13 +1 -1
    See if cast is enough to quiet Veracode int truncation warning

  ntpd/ntp_config.c@1.199 +7 -3
    sprintf()->snprintf()
    check for unlink() failure

  ntpd/ntp_control.c@1.112 +28 -27
    strcpy() + strcat() -> snprintf()
    strcpy() -> memcpy()
    correct 'be" buffer end calculations

  ntpd/ntp_intres.c@1.64 +7 -3
    check for unlink() failure
    ensure zero termination with strncpy()

  ntpd/ntp_io.c@1.295 +1 -0
    ensure null termination with strncpy

  ntpd/ntp_scanner.c@1.22 +30 -5
    bounds-check access to yytext[]

  ntpd/ntp_signd.c@1.2 +1 -4
    use emalloc()

  ntpd/ntp_util.c@1.73 +8 -3
    check for rename(), _unlink() failures

  ntpd/ntpd.c@1.106 +7 -3
    add chdir("/") after chroot(), can't hurt and Veracode wants it

  ntpd/refclock_acts.c@1.36 +0 -3
    emalloc() never returns NULL

  ntpd/refclock_bancomm.c@1.11 +2 -3
    use emalloc()

  ntpd/refclock_datum.c@1.13 +1 -1
    use emalloc()

  ntpd/refclock_oncore.c@1.78 +7 -24
    use emalloc()

  ntpdate/ntpdate.c@1.68 +1 -1
    use emalloc()

  ntpdc/ntpdc.c@1.67 +1 -5
    use emalloc()

  ntpq/ntpq-subs.c@1.32 +2 -26
    remove strsave from ntpq, same as libntp's estrdup()

  ports/winnt/libisc/isc_strerror.c@1.8 +9 -6
    use emalloc()
    #undef our strerror() before calling the CRT version, infinite 
      recursion is no fun

  ports/winnt/ntpd/ntp_iocompletionport.c@1.47 +8 -5
    calloc() -> emalloc() then memset zero

  refclock_oncore.c:
    BUG[no bug report] This code adds a message for TRAIM messages.  Users often worry about the
    driver not starting up, and it is often because of signal strength being low.
    Low signal strength will give TRAIM messages.
    BUG[1220] OK, big patch, but mostly done mechanically.  Change direct calls to write
    to clockstats to a call to oncore_log, which now calls the old routine plus msyslog.
    Have to set the LOG_LEVELS of the calls for msyslog, and this was done by hand. New
    routine oncore_log.
    BUGS[no bug report] Users often worry that the code is hung when there is 
    no output after a restart.  If the receiver does not have battery backup
    can take up to 30minutes to acuqire an almanac and this is necessary before
    the driver can start.  This message should reasurre the user that the driver
    has not died.

    ---
    bump cache version due to changes in sntp and gsoc_sntp gethostent
    library search order, the result of which is cached and shared with

  * [Bug 1165] Clean up small memory leaks in the  config file parser
  * Correct logconfig keyword declaration to MULTIPLE_ARG
  * Enable filename and line number leak reporting on Windows when built
    DEBUG for all the typical C runtime allocators such as calloc,
    malloc, and strdup.  Previously only emalloc calls were covered.
  * Add DEBUG-only code to free dynamically allocated memory that would
    otherwise remain allocated at ntpd exit, to allow less forgivable
    leaks to stand out in leaks reported after exit.
  * Ensure termination of strings in ports/winnt/libisc/isc_strerror.c
    and quiet compiler warnings.

  The oncore hardware provides a 'negative saw-tooth' the offset of the PPS signal
  which is on the zero crossing of its internal clock, from its true value.  the
  refclock_oncore.c driver applies this difference to correct the time of the
  provided timestamp.  This value was being applied correctly for the 6 and 8 channel
  receivers, but not for the 12 channel.  This has been corrected.

    refclock_oncore.c driver applies this difference to correct the time of the
    provided timestamp.  This value was being applied correctly for the 6 and 8 channel
    receivers, but not for the 12 channel.  This has been corrected.

    findlocalinterface() in update_interface can be replaced by
    a simple address to interface lookup. This avoids tripping
    over the Linux strategy to return the localhost address
    when attempting to send to an IPv6 address of a local interface.
    Additionally:
      synchronize debug output with reality
      avoid adding duplicate address entries to the address list
      declare more functions static to reduce name space pollution

  Fixes from Dave.

  ntpd/ntp_loopfilter.c@1.124 +22 -22
    Dave sez:
    
    At cold start (no frequency file) the daemon sets the clock at the
    first update, then waits 15 minutes, measures and corrects the
    frequency (usually within 1 PPM) and assumes normal operation. This
    saves many hours to converge the frequency within 1 PPM, especially
    if the intrinsic frequency error is large, like 200 PPM.
    
    Until the frequency is corrected, the machine can have serious
    offset and frequency errors that would drive dependent clients nuts.
    Up to now, the leap bits and stratum were not initialized until the
    frequency was corrected. However, the clock was set and local clients
    were free to believe or not believe the clock. After review, the
    external behavior is only mildly worse than without the initial
    training period, so the leap bits and stratum are now set at the
    first update. The billboards should now be consistent with the
    Principle of Least Astonishment.

    saves many hours to converge the frequency within 1 PPM, especially
    if the intrinsic frequency error is large, like 200 PPM.
    
    Until the frequency is corrected, the machine can have serious
    offset and frequency errors that would drive dependent clients nuts.
    Up to now, the leap bits and stratum were not initialized until the
    frequency was corrected. However, the clock was set and local clients
    were free to believe or not believe the clock. After review, the
    external behavior is only mildly worse than without the initial
    training period, so the leap bits and stratum are now set at the
    first update. The billboards should now be consistent with the
    Principle of Least Astonishment.

    We know that peer_leap can be LEAPNOTINSYNC from startup (peer_clear when

    Fixes from Dave Mills.  In particular, Dave writes:
  
    After discovering the situation reported on the newsgroup where 
    misconfigured NTP had the Netgear disease, I put it through some 
    wickedly broken configuration tests and found and fixed a few minor 
    things in ntp-dev (not anything like the PPS oscillator).
  
    1. If a notrust error and iburst are configured, the client did not back 
    off the poll interval. It now does that under all circumstances where 
    the reply is absent or corrupt.
  
    2. An unresponsive server with iburst got hammered with eight messages 
    every poll interval until the unreach counter reaches 12, then backs off 
    sending only a single packet per burst. I changed that to send a burst 
    only the first time after initial start or loss of reach.
  
    3. By popular demand I put in "tos maxdist N", where N is the selection 
    threshold, normally 1. Set N to 16 and the clock will be set upon first 
    receiving a response from any server. Y'know, like SNTP.

  Changes from Dave Mills:
  
  1. Servers presented with key IDs they don't have (a common mistake)
  return a crypt-NAK. This also happens when the server rolls new private
  values daily without telling the clients. To protect against bad guys
  tossing an old duplicate over the wall, the client doesn't believe this
  unless the timestamps pass the loopback check. If the server was
  previously reachable, the client simply restarts the association without
  missing a beat. If not, and to protect against a restart loop or later
  server restart, the client disregards the NAK and continues (while
  disabling burst mode). If really invalid, the association timeout will
  eventually expire following which a persistent association is marked
  permanently disabled or an ephemeral association is demobilized.
  
  2. One of the most common mistakes is to goof up the identity
  credentials. If the client received these credentials via mail, the
  script in the message installs the file and link automatically. If done
  by hand and done wrong, either the server or client will find the error
  and disable the association. As in all such cases, a server or client
  ephemeral association is demobilized and the resources recovered.
  
  3. Symmetric modes have always been tricky, much more so with Autokey,
  and even more so with misconfigured identity keys. It gets even wilder
  when either peer is restarted in the middle of negotiations. All the
  evil scenarios I can thing of seem to come out on the other side,
  although there are a few that have to wait the association timeout to
  properly close down and recover resources.
  
  4. The association is permanently disabled upon kiss-o'-death or
  unrecoverable crypto error. So, I re-enabled log reporting for these
  smooches. At least the offender is notified.
  
  5. When a really tenacious clogger shows up and lights the call-gap, the
  server puts it in the restrict list. He stays there until the server is
  restarted. Not only does this discourage the terriot, but evidence is
  collected for possible further action.
  
  What more do we have to do to turn this stuff into a real Secure
  Timestamping Service? I think the security model, protocols, abuse
  hardening and time performance are consistent with a bulletproof service
  assuming, that is, PGP mail is used to get the keys and the server
  certificates are properly signed.

    some (minor) changes:
       (a) some changes to messages printed.
       (b) can now find config file in /etc/ntp/ as well as /etc/
    
    Bug 233: New LP64 Patches
    patch imported from original author
    
    Bug 246: 3 issues with the ONCORE driver
    (1) You can reset the ONCORE driver back to defaults by *reading*
        the variables from across the net.
    
    This bug was introduced when I (foolishly) 'fixed' the code so it
    would understand the FLAG variables that corresponded to its own
    input variables from the ntp.ONCORE.x file.  Since I do NOT understand
    all the implications of ntp_control, I will remove this 'fix'.
    The variables can now only be set in ntp.ONCORE.  They can NOT be
    changed dynamically.  The documentation will be changed back.  Perhaps
    at some time in the future I will dig through the ntp code to
    understand ntp_control.
    
    (2) Fudge acted upon AFTER ntp.ONCORE.
    
    Fixed by (1) the FUDGE flag/time variables are ignored, use the
    ntp.ONCORE file.
    
    (3) In the driver, ONCORE_start and a few other procedures do not
        produce any output in the clockstats file.
    
    The originator of the bug is running FreeBSD 5.1.
    I have looked at the output from MY copy of FreeBSD 5.1, and several
    Linux versions (7.3 -> 9), and Fedora and do NOT see any missing
    messages.  The messages start with an "ONCORE DRIVER -- CONFIGURING"
    message written when the driver is first entered, and contain all the
    messages I would expect after that.
    
    I have no idea why he is not seeing the messages.
    
    No action.
    
    Bug 260, Patches for item (1) in the above.
    
    The patch purports to fix the problem in Bug 246.
    
    As noted I don't understand the details of what is going on behind the
    curtain, so I would rather remove the offending code, than try to fix it.
    
    There is also an increase buffer size so that longer messages can be
    sent to the clockstats file.  Ill leave that for the user to do on his
    own if he wants to change the messages, but with slightly more effort
    he could do the same using SHMEM.

  Fixes to properly support platforms that do not have IPv6 support.

  include/isc/ipv6.h@1.4 +4 -2
    Make IPv6 Macro definitions only if not previously defined.

  include/ntp_rfc2553.h@1.10 +2 -4
    Change to only use the definitions if IPv6 not defined on the platform. This uses the
    Macros defined during the config process which defines the Macro
    ISC_PLATFORM_HAVEIPV6 if the platform properly supports IPv6

  libntp/ntp_rfc2553.c@1.15 +2 -2
    Use ISC_PLATFORM_HAVEIPV6 instead of HAVE_IPV6 which was previously
    defined in the ntp_rfc2553.h file based on the erroneously assumption about a
    macro.

  ports/winnt/include/isc/ipv6.h@1.3 +4 -2
    Make IPv6 Macro definitions only if not previously defined.

  ports/winnt/include/isc/platform.h@1.3 +5 -0
    The ISC_PLATFORM_HAVEIPV6 macro should not have been defined here.
    This was a vestige of the work being done to scan for IPv6 interfaces on
    Windows platforms.
