It's even easier if you use debmake, just call build. (Note that the Debian files are not distributed with the original source anymore. You have to get the Debian .diff.gz file, too.) If you use redhat, you can use the .spec file to generate a package. But as with Debian you have to get the .spec file from the RedHat sources. Copy watchdog.spec to /usr/src/redhat/SPECS, copy the .tar.gz archive to /usr/src/redhat/SOURCES, cd /usr/src/redhat/SPECS, rpm -ba watchdog.spec. (Note that the watchdog.spec file not distributed with the original source either.) If your Linux distribution does not include watchdog feel free to ask the distributor to add it. Since watchdog is GPLed there should not be a problem. Okay, if you want to install it manually: $ autoreconf -i (if you're building from CVS) $ ./configure $ make $ su # make install There are several options available which can be listed by running $ ./configure --help We only list some options here which are generally useful. Symbols: *cl - can be overridden in the command line *cf - can be overridden in the config file --with-sleep-interval=sec (default 10) *cl *cf This allows you to set the default number of seconds which watchdog will sleep before acting again. --with-sysadmin=email (default root) *cf If watchdog attempts to reboot a machine, it will try to send an email out before that. You can set the email address of the recipient with this option. --with-maxload=int (default 12) *cf If the load average reaches this point, the machine will reboot. --with-watchdog=path (default /dev/watchdog) *cf --with-temperature=path (default /dev/temperature) *cf Sets the path for the respective device.

If configured so it only opens .IR /dev/watchdog , and keeps writing to it often enough to keep the kernel from resetting, at least once per minute. Each write delays the reboot time another minute. After a minute of inactivity the watchdog hardware will cause a reset. In the case of the software watchdog the ability to reboot will depend on the state of the machines and interrupts. .PP The wd_keepalive daemon can be stopped without causing a reboot if the device .I /dev/watchdog is closed correctly, unless your kernel is compiled with the .I CONFIG_WATCHDOG_NOWAYOUT option enabled. .PP Under high system load .B wd_keepalive might be swapped out of memory and may fail to make it back in in time. Under these circumstances the Linux kernel will reset the machine. To make sure you won't get unnecessary reboots make sure you have the variable .I realtime set to .I yes in the configuration file .IR watchdog.conf . This adds real time support to .BR wd_keepalive : it will lock itself into memory and there should be no problem even under the highest of loads. .PP On system running out of memory the kernel will try to free enough memory by killing process. The .B wd_keepalive daemon itself is exempted from this so-called out-of-memory killer. .SH OPTIONS Available command line options are the following: .TP .BR \-c " \fIconfig-file\fR, " \-\-config\-file " \fIconfig-file" Use .I config-file as the configuration file instead of the default .IR /etc/watchdog.conf . .SH FILES .TP .I /dev/watchdog The watchdog device. .TP .I /var/run/wd_keepalive.pid The pid file of the running .BR wd_keepalive . .SH "SEE ALSO" .BR watchdog.conf (5) .TP .BR watchdog (8) watchdog-5.13/watchdog.conf.50000644000175000017500000001331112102721740015635 0ustar michaelmichael.TH WATCHDOG.CONF 5 "January 2005" .UC 4 .SH NAME watchdog.conf \- configuration file for the watchdog daemon .SH DESCRIPTION This file carries all configuration options for the Linux watchdog daemon. Each option has to be written on a line for itself. Comments start with '#'. Blanks are ignored except after the '=' sign. An empty text after the '=' sign disables the feature as long as that makes sense. .SH OPTIONS .TP interval = Set the interval between two writes to the watchdog device. The kernel drivers expects a write command every minute. Otherwise the system will be rebooted. Default value is 1 second. An interval of more than a minute can only be used with the \-f command-line option. .TP logtick = If you enable verbose logging, a message is written into the syslog or a logfile. While this is nice, it is not necessary to get a message every 10 seconds which really fills up disk and needs CPU. logtick allows adjustment of the number of intervals skipped before a log message is written. If you use logtick = 60 and interval = 10, only every 10 minutes (600 seconds) a message is written. This may make the exact time of a crash harder to find but greatly reduces disk usage and administrator nerves if you're looking for a particular syslog entry in between of watchdog messages. .TP max-load-1 = Set the maximal allowed load average for a 1 minute span. Once this load average is reached the system is rebooted. Default value is 0. That means the load average check is disabled. Be careful not to this parameter too low. To set a value less then the predefined minimal value of 2, you have to use the \-f commandline option. .TP max-load-5 = Set the maximal allowed load average for a 5 minute span. Once this load average is reached the system is rebooted. Default value is 3/4*max-load-1. Be careful not to this parameter too low. To set a value less then the predefined minimal value of 2, you have to use the \-f commandline option. .TP max-load-15 = Set the maximal allowed load average for a 15 minute span. Once this load average is reached the system is rebooted. Default value is 1/2*max-load-1. Be careful not to this parameter too low. To set a value less then the predefined minimal value of 2, you have to use the \-f commandline option. .TP min-memory = Set the minimal amount of virtual memory that has to stay free. Note that this is in pages. Default value is 0 pages which means this test is disabled. The page size is taken from the system include files. .TP max-temperature = Set the maximal allowed temperature. Once this temperature is reached the system is halted. Default value is 120. There is no unit conversion, so make sure you use the same unit as your hardware. Watchdog will issue warnings once the temperature increases 90%, 95% and 98% of this temperature. .TP watchdog-device = Set the watchdog device name. Default is to disable keep alive support. .TP watchdog-timeout = Set the watchdog device timeout during startup. If not set, the default is driver-dependent. .TP temperature-device = Set the temperature device name. Default is to disable temperature checking. .TP file = Set file name for file mode. This option can be given as often as you like to check several files. .TP change = Set the change interval time for file mode. This options always belongs to the active filename, that is when finding a 'change =' line watchdog assumes it belongs to the most recently read 'file =' line. They don't neccessarily have to follow each other directly. But you cannot specify a 'change =' before a 'file ='. The default is to only stat the file and don't look for changes. Using this feature to monitor changes in /var/log/messages might require some special syslog daemon configuration, e.g. rsyslog needs "$ActionWriteAllMarkMessages on" to be set to make sure the marks are written no matter what. .TP pidfile = Set pidfile name for server test mode. This option can be given as often as you like to check several servers. .TP ping = Set IP address for ping mode. This option can be used more than once to check different connections. .TP interface = Set interface name for network mode. This option can be used more than once to check different interfaces. .TP test-binary = Execute the given binary to do some user defined tests. .TP test-timeout = User defined tests may only run for seconds. Set to 0 for unlimited. .TP repair-binary = Execute the given binary in case of a problem instead of shutting down the system. .TP repair-timeout = repair command may only run for seconds. Set to 0 for unlimited. .TP admin = Email address to send admin mail to. That is, who shall be notified that the machine is being halted or rebooted. Default is 'root'. If you want to disable notification via email just set admin to en empty string. .TP realtime = If set to yes watchdog will lock itself into memory so it is never swapped out. .TP priority = Set the schedule priority for realtime mode. .TP test-directory = Set the directory to run user test/repair scripts. Default is '/etc/watchdog.d' See the Test Directory section in watchdog(8) for more information. .TP log-dir = Set the log directory to capture the standard output and standard error from repair-binary and test-binary execution. Default is '/var/log/watchdog'. .SH FILES .TP .I /etc/watchdog.conf The watchdog configuration file .TP .I /etc/watchdog.d A directory containing test-or-repair commands.

Instructions for how to set up the watchdog daemon to work with IPMI's hardware watchdog ---------------------------------------------------------------------------------------- First, verify that the ipmitool utility is present on the system to allow the watchdog timer to be turned off via the command line (which ipmitool). This will allow the hardware watchdog timer to be turned off gracefully should it ever become necessary. If ipmitool is not present, install it or download the latest version from http://ipmitool.sourceforge.net and build and install it on your system. Next, prior to starting up the watchdog daemon, the BMC BIOS should be set to enable the IPMI/BMC hardware watchdog timer, the OpenIPMI watchdog driver module should be inserted with the desired configuration/startup settings, and the watchdog daemon's configuration file should be modified to use /dev/watchdog: 1. To setup the IPMI/BMC BIOS to enable the hardware watchdog timer, see BMC documentation. The main settings in the BMC BIOS requiring modification to turn on the IPMI watchdog timer are: - Set the BMC POST Watchdog to "ENABLED". - Set the BMC POST Watchdog Timeout to "5 Minutes". 2. To insert the OpenIPMI watchdog driver module with the desired configuration settings, two steps are necessary: i.) Configure the OpenIPMI watchdog driver by editing the /etc/sysconfig/ipmi configuration file: - Set "IPMI_WATCHDOG=yes". - Set desired options via the IPMI_WATCHDOG_OPTIONS config entry. EXAMPLE: 'IPMI_WATCHDOG_OPTIONS="timeout=60 start_now=1 \ preop=preop_give_data action=power_cycle pretimeout=1" ' Execute "modinfo ipmi_watchdog" for more detailed information on the available ipmi watchdog timer options. - Execute "service ipmi start" (the watchdog driver starts automatically along with the other ipmi drivers). IMPORTANT: If "start_now=1" has been set as one of the configuration options, be sure to start up the watchdog daemon before the BMC timer expires! ii.) Set the OpenIPMI daemon and watchdog to start during bootup: - chkconfig ipmi on - chkconfig watchdog on 3. Configure the watchdog daemon by editing the /etc/watchdog.conf configuration file: - Uncomment the "watchdog-device = /dev/watchdog" line. - Ensure that "realtime = yes" and "priority = 1" are set and not commented-out. - Uncomment the "interval" line, and set the interval to be less than what you set the timeout option to be in the /etc/sysconfig/ipmi file (ex "timeout=60" so you might set interval to 50). So in the example described herein, the BMC BIOS setting is in minutes (5), and the "interval" and ipmi_watchdog "timeout" settings are both in seconds (50 and 60 respectively). Therefore, the BMC hardware watchdog timer is set to expire and trigger a system power cycle unless reset by the watchdog daemon within 5 minutes, and the watchdog daemon will reset the timer every 60 seconds. 4. Start the Watchdog daemon: - execute "service watchdog start" IMPORTANT: To gracefully stop/kill the watchdog daemon, be sure to use "service watchdog stop" (which executes "kill -s SIGTERM ") and do *not* use "kill -9 ". Using "kill -9 " will cause the daemon to be shut off without stopping the BMC's watchdog timer, thus a system reboot will be triggered when the BMC's watchdog timer expires. Alternately, or in case the watchdog daemon is killed "ungracefully", you can stop the BMC timer by executing the following ipmitool utility command before the watchdog timer expires: # ipmitool -v raw 0x06 0x24 0x04 0x01 0x00 0x10 0x00 0x0a ---------------------------------------------------------------------- To test the watchdog after system configuration and setup: . Use kill -9 on the watchdog daemon so it doesn't shut down the watchdog daemon gracefully. Verify that the system gets reset after the BMC timer expires. . Use "service watchdog stop" and verify that the watchdog daemon shuts off the BMC watchdog timer gracefully (the system doesn't get reset). . Set the timer on the watchdog daemon to be greater than the time set in the BMC BIOS for system reset and verify that the system is reset. . Set the timer on the daemon to be less than the time set in the BMC timer and verify that the BMC watchdog is poked regularly and the system is not reset. . Test some of the other actions the BMC can take when the watchdog timer goes off (see modinfo ipmi_watchdog for some other settings to try). watchdog-5.13/watchdog.conf0000644000175000017500000000211612102721740015473 0ustar michaelmichael#ping = 172.31.14.1 #ping = 172.26.1.255 #interface = eth0 #file = /var/log/messages #change = 1407 # Uncomment to enable test.

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.

This configuration file is also used to set the watchdog to be used as a hardware watchdog instead of its default software watchdog operation. In either case, if the device is open but not written to within the configured time period, the watchdog timer expiration will trigger a machine reboot. When operating as a software watchdog, the ability to reboot will depend on the state of the machine and interrupts. When operating as a hardware watchdog, the machine will experience a hard reset (or whatever action was configured to be taken upon watchdog timer expiration) initiated by the BMC. %prep %setup -q -n %{name}-%{version} cp %{SOURCE2} . cp %{SOURCE3} . %patch0 -p1 -b .cleanup %patch1 -p1 -b .cleanup-nfs mv README README.orig iconv -f ISO-8859-1 -t UTF-8 < README.orig > README %build %configure make %{?_smp_mflags} %install rm -Rf ${RPM_BUILD_ROOT} install -d -m0755 ${RPM_BUILD_ROOT}%{_sysconfdir} make DESTDIR=${RPM_BUILD_ROOT} install install -Dp -m0644 %{name}.sysconfig ${RPM_BUILD_ROOT}%{_sysconfdir}/sysconfig/watchdog install -Dp -m0755 %{SOURCE1} ${RPM_BUILD_ROOT}%{_initrddir}/watchdog %clean rm -Rf ${RPM_BUILD_ROOT} %post if [ $1 -eq 1 ]; then /sbin/chkconfig --add %{name} fi %preun if [ $1 -eq 0 ]; then /sbin/service %{name} stop >/dev/null 2>&1 /sbin/chkconfig --del %{name} fi %postun if [ $1 -ge 1 ]; then /sbin/service %{name} condrestart >/dev/null 2>&1 fi %files %defattr(-, root, root, -) %doc AUTHORS ChangeLog COPYING examples/ IAFA-PACKAGE NEWS README TODO README.watchdog.ipmi README.Fedora %config(noreplace) %{_sysconfdir}/watchdog.conf %config(noreplace) %{_sysconfdir}/sysconfig/watchdog %{_sysconfdir}/rc.d/init.d/watchdog %{_sbindir}/watchdog %{_sbindir}/wd_keepalive %{_mandir}/man5/watchdog.conf.5* %{_mandir}/man8/watchdog.8* %{_mandir}/man8/wd_keepalive.8* %changelog * Thu Mar 5 2009 Richard W.M.

It implements a userspace daemon which periodically pings (usually hardware) to tell the hardware that the machine is alive. If the hardware times out without receiving a ping, it assumes userspace is dead and reboots the machine. There are several major classes of watchdog available: - watchdog hardware implementing the Linux /dev/watchdog API * drivers in /lib/modules/$(uname -r)/kernel/drivers/watchdog/ * http://lxr.linux.no/linux/Documentation/watchdog/watchdog-api.txt - softdog * software watchdog (just runs inside the kernel) * implements the Linux /dev/watchdog API * won't help you if the kernel fails (obvious, right?) - IPMI * a heavyweight standard for all things server-management * separate Linux driver * ipmitool to control it * see README.watchdog.ipmi for how to use this daemon together with IPMI You can also use watchdogs inside recent QEMU/KVM virtual machines. When running qemu, specify "-watchdog i6300esb" on the qemu command line (or use libvirt). Inside the guest, the i6300esb watchdog driver should automatically load and provide you with a Linux /dev/watchdog- compatible API. - Richard W.M.

This tool proved very useful for me, because I always run the latest kernel and the latest libc release, but rely on the machine to be up and running for email. Note, that you have to enable the software watchdog driver in your kernel for the program to be able to hard reset the system unless you have a hardware watchdog of course. Make sure you don't compile watchdog with a different timer margin than the kernel driver. As of version 4.0 watchdog is able to make itself a real-time application. It will lock all its pages in memory and set it´s scheduler to round-robin. This will take up to 900 pages of memory but guarantees you that watchdog will get its share of processor time. If you ever experienced a hard reset just because watchdog wasn´t scheduled for a minute, you will probably have no problem with the 900 pages which is not so much anyway. Of course this is not needed for machines running on low load. Don't be surprised if you see any zombie processes laying around. This is normal. They will be removed the next time watchdog wakes up. Of course a new zombie is created then, too. This zombie process is a result of the process table check.

This can be implemented via special watchdog hardware, or via a slightly less reliable software-only watchdog inside the kernel. Either way, there needs to be a daemon that tells the kernel the system is working fine. If the daemon stops doing that, the system is reset. .PP .B watchdog is such a daemon. It opens .IR /dev/watchdog , and keeps writing to it often enough to keep the kernel from resetting, at least once per minute. Each write delays the reboot time another minute. After a minute of inactivity the watchdog hardware will cause the reset. In the case of the software watchdog the ability to reboot will depend on the state of the machines and interrupts. .PP The watchdog daemon can be stopped without causing a reboot if the device .I /dev/watchdog is closed correctly, unless your kernel is compiled with the .I CONFIG_WATCHDOG_NOWAYOUT option enabled. .SH TESTS The watchdog daemon does several tests to check the system status: .IP \(bu 3 Is the process table full? .IP \(bu 3 Is there enough free memory? .IP \(bu 3 Are some files accessible? .IP \(bu 3 Have some files changed within a given interval? .IP \(bu 3 Is the average work load too high? .IP \(bu 3 Has a file table overflow occurred? .IP \(bu 3 Is a process still running? The process is specified by a pid file. .IP \(bu 3 Do some IP addresses answer to ping? .IP \(bu 3 Do network interfaces receive traffic? .IP \(bu 3 Is the temperature too high? (Temperature data not always available.) .IP \(bu 3 Execute a user defined command to do arbitrary tests. .IP \(bu 3 Execute one or more test/repair commands found in /etc/watchdog.d. These commands are called with the argument \fBtest\fP or \fBrepair\fP. .PP If any of these checks fail watchdog will cause a shutdown. Should any of these tests except the user defined binary last longer than one minute the machine will be rebooted, too. .PP .SH OPTIONS Available command line options are the following: .TP .BR \-v ", " \-\-verbose Set verbose mode. Only implemented if compiled with .I SYSLOG feature. This mode will log each several infos in .I LOG_DAEMON with priority .IR LOG_INFO. This is useful if you want to see exactly what happened until the watchdog rebooted the system. Currently it logs the temperature (if available), the load average, the change date of the files it checks and how often it went to sleep. .TP .BR \-s ", " \-\-sync Try to synchronize the filesystem every time the process is awake. Note that the system is rebooted if for any reason the synchronizing lasts longer than a minute. .TP .BR \-b ", " \-\-softboot Soft-boot the system if an error occurs during the main loop, e.g. if a given file is not accessible via the .BR stat (2) call. Note that this does not apply to the opening of .I /dev/watchdog and .IR /proc/loadavg , which are opened before the main loop starts. .TP .BR \-F ", " \-\-foreground Run in foreground mode, useful for running under systemd (for example). .TP .BR \-f ", " \-\-force Force the usage of the interval given or the maximal load average given in the config file. .TP .BR \-c " \fIconfig-file\fR, " \-\-config\-file " \fIconfig-file" Use .I config-file as the configuration file instead of the default .IR /etc/watchdog.conf . .TP .BR \-q ", " \-\-no\-action Do not reboot or halt the machine. This is for testing purposes. All checks are executed and the results are logged as usual, but no action is taken. Also your hardware card or the kernel software watchdog driver is not enabled. Temperature checking is also disabled since this triggers the hardware watchdog on some cards. .SH FUNCTION After .B watchdog starts, it puts itself into the background and then tries all checks specified in its configuration file in turn. Between each two tests it will write to the kernel device to prevent a reset. After finishing all tests watchdog goes to sleep for some time. The kernel drivers expects a write to the watchdog device every minute. Otherwise the system will be reset. As a default .B watchdog will sleep for only 1 second so it triggers the device early enough. .PP Under high system load .B watchdog might be swapped out of memory and may fail to make it back in in time. Under these circumstances the Linux kernel will reset the machine. To make sure you won't get unnecessary reboots make sure you have the variable .I realtime set to .I yes in the configuration file .IR watchdog.conf . This adds real time support to .BR watchdog : it will lock itself into memory and there should be no problem even under the highest of loads. .PP On system running out of memory the kernel will try to free enough memory by killing process. The .B watchdog daemon itself is exempted from this so-called out-of-memory killer. .PP Also you can specify a maximal allowed load average. Once this load average is reached the system is rebooted. You may specify maximal load averages for 1 minute, 5 minutes or 15 minutes. The default values is to disable this test. Be careful not to set this parameter too low. To set a value less then the predefined minimal value of 2, you have to use the .B -f option. .PP You can also specify a minimal amount of virtual memory you want to have available as free. As soon as more virtual memory is used action is taken by .BR watchdog . Note, however, that watchdog does not distinguish between different types of memory usage. It just checks for free virtual memory. .PP If you have a watchdog card with temperature sensor you can specify the maximal allowed temperature. Once this temperature is reached the system is halted. The default value is 120. There is no unit conversion so make sure you use the same unit as your hardware. .B watchdog will issue warnings once the temperature increases 90%, 95% and 98% of this temperature. .PP When using file mode .B watchdog will try to .BR stat (2) the given files. Errors returned by stat will .B not cause a reboot. For a reboot the stat call has to last at least one minute. This may happen if the file is located on an NFS mounted filesystem. If your system relies on an NFS mounted filesystem you might try this option. However, in such a case the .I sync option may not work if the NFS server is not answering. .PP .B watchdog can read the pid from a pid file and see whether the process still exists. If not, action is taken by .BR watchdog . So you can for instance restart the server from your .IR repair-binary . .PP .B watchdog will try periodically to fork itself to see whether the process table is full. This process will leave a zombie process until watchdog wakes up again and catches it; this is harmless, don't worry about it. .PP In ping mode .B watchdog tries to ping the given IP addresses. These addresses do not have to be a single machine. It is possible to ping to a broadcast address instead to see if at least one machine in a subnet is still living. .PP .B Do not use this broadcast ping unless your MIS person a) knows about it and .B b) has given you explicit permission to use it! .PP .B watchdog will send out three ping packages and wait up to seconds for the reply with being the time it goes to sleep between two times triggering the watchdog device. Thus a unreachable network will not cause a hard reset but a soft reboot. .PP You can also test passively for an unreachable network by just monitoring a given interface for traffic. If no traffic arrives the network is considered unreachable causing a soft reboot or action from the repair binary. .PP .B watchdog can run an external command for user-defined tests. A return code not equal 0 means an error occured and watchdog should react. If the external command is killed by an uncaught signal this is considered an error by watchdog too. The command may take longer than the time slice defined for the kernel device without a problem. However, error messages are generated into the syslog facility. If you have enabled softboot on error the machine will be rebooted if the binary doesn't exit in half the time .B watchdog sleeps between two tries triggering the kernel device. .PP If you specify a repair binary it will be started instead of shutting down the system. If this binary is not able to fix the problem .B watchdog will still cause a reboot afterwards. .PP If the machine is halted an email is sent to notify a human that the machine is going down. Starting with version 4.4 .B watchdog will also notify the human in charge if the machine is rebooted. .SH "SOFT REBOOT" A soft reboot (i.e. controlled shutdown and reboot) is initiated for every error that is found. Since there might be no more processes available, watchdog does it all by himself. That means: .IP 1. 4 Kill all processes with SIGTERM. .IP 2. 4 After a short pause kill all remaining processes with SIGKILL. .IP 3. 4 Record a shutdown entry in wtmp. .IP 4. 4 Save the random seed from .IR /dev/urandom . If the device is non-existant or there is no filename for saving this step is skipped. .IP 5. 4 Turn off accounting. .IP 6. 4 Turn off quota and swap. .IP 7. 4 Unmount all partitions except the root partition. .IP 8. 4 Remount the root partition read-only. .IP 9. 4 Shut down all network interfaces. .IP 10. 4 Finally reboot. .SH "CHECK BINARY" If the return code of the check binary is not zero .B watchdog will assume an error and reboot the system. Be careful with this if you are using the real-time properties of watchdog since .B watchdog will wait for the return of this binary before proceeding. An positive exit code is interpreted as an system error code (see .I errno.h for details). Negative values are special to .BR watchdog : .TP \-1 Reboot the system. This is not exactly an error message but a command to .BR watchdog . If the return code is \-1 .B watchdog will not try to run a shutdown script instead. .TP \-2 Reset the system. This is not exactly an error message but a command to .BR watchdog . If the return code is \-2 .B watchdog will simply refuse to write the kernel device again. .TP \-3 Maximum load average exceeded. .TP \-4 The temperature inside is too high. .TP \-5 .I /proc/loadavg contains no (or not enough) data. .TP \-6 The given file was not changed in the given interval. .TP \-7 .I /proc/meminfo contains invalid data. .TP \-8 Child process was killed by a signal. .TP \-9 Child process did not return in time. .TP \-10 Free for personal use. .SH "REPAIR BINARY" The repair binary is started with one parameter: the error number that caused .B watchdog to initiate the boot process. After trying to repair the system the binary should exit with 0 if the system was successfully repaired and thus there is no need to boot anymore. A return value not equal 0 tells .B watchdog to reboot. The return code of the repair binary should be the error number of the error causing .B watchdog to reboot. Be careful with this if you are using the real-time properties since .B watchdog will wait for the return of this binary before proceeding. .SH "TEST DIRECTORY" Executables placed in the test directory are discovered by watchdog on startup and are automatically executed. They are bounded time-wise by the test-timeout directive in watchdog.conf. These executables are called with either "test" as the first argument (if a test is being performed) or "repair" as the first argument (if a repair for a previously-failed "test" operation on is being performed). The as with test binaries and repair binaries, expected exit codes for a successful test or repair operation is always zero. If an executable's test operation fails, the same executable is automatically called with the "repair" argument as well as the return code of the previously-failed test operation. For example, if the following execution returns 42: /etc/watchdog.d/my-test test The watchdog daemon will attempt to repair the problem by calling: /etc/watchdog.d/my-test repair 42 This enables administrators and application developers to make intelligent test/repair commands. If the "repair" operation is not required (or is not likely to succeed), it is important that the author of the command return a non-zero value so the machine will still reboot as expected. Note that the watchdog daemon may interpret and act upon any of the reserved return codes noted in the Check Binary section prior to calling a given command in "repair" mode. .SH BUGS None known so far. .SH AUTHORS The original code is an example written by Alan Cox , the author of the kernel driver. All additions were written by Michael Meskes . Johnie Ingram had the idea of testing the load average. He also took over the Debian specific work. Dave Cinege brought up some hardware watchdog issues and helped testing this stuff. .SH FILES .TP .I /dev/watchdog The watchdog device. .TP .I /var/run/watchdog.pid The pid file of the running .BR watchdog . .SH "SEE ALSO" .BR watchdog.conf (5) watchdog-5.13/debian/0002755000175000017500000000000012102721740014250 5ustar michaelmichaelwatchdog-5.13/debian/dirs0000644000175000017500000000004512102721740015131 0ustar michaelmichaeletc/init.d usr/sbin var/log/watchdog watchdog-5.13/debian/prerm0000644000175000017500000000022412102721740015314 0ustar michaelmichael#!/bin/sh set -e if [ \( "$1" = "upgrade" -o "$1" = "remove" \) -a -L /usr/doc/watchdog ]; then rm -f /usr/doc/watchdog fi #DEBHELPER# watchdog-5.13/debian/control0000644000175000017500000000203512102721740015651 0ustar michaelmichaelSource: watchdog Section: admin Priority: extra Maintainer: Michael Meskes Build-Depends: debhelper (>= 5), po-debconf (>= 0.5.0) Standards-Version: 3.9.3 Homepage: http://watchdog.sourceforge.net Package: watchdog Architecture: any Depends: ${shlibs:Depends}, ${misc:Depends}, makedev (>= 2.3.1-24) | udev, lsb-base (>= 3.2-14) Description: system health checker and software/hardware watchdog handler The watchdog program writes to /dev/watchdog every ten seconds. If the device is opened but not written to within a minute, the machine will reboot. This feature is available when the kernel is built with "software watchdog" support (standard in Debian kernels) or if the machine is equipped with a hardware watchdog (in which case this package can also be used to "pet" it, resetting its timer). . The kernel software watchdog's ability to reboot will depend on the state of the machine and interrupts. . The watchdog tool itself runs several health checks and acts appropriately if the system is not in good shape. watchdog-5.13/debian/wd_keepalive.init0000644000175000017500000000407212102721740017575 0ustar michaelmichael#!/bin/sh #/etc/init.d/wd_keepalive: start wd_keepalive daemon. ### BEGIN INIT INFO # Provides: wd_keepalive # Short-Description: Start watchdog keepalive daemon # Required-Start: $remote_fs # Required-Stop: $remote_fs # X-Start-Before: $all # Default-Start: 2 3 4 5 # Default-Stop: ### END INIT INFO PATH=/bin:/usr/bin:/sbin:/usr/sbin test -x /usr/sbin/wd_keepalive || exit 0 # For configuration of the init script use the file # /etc/default/watchdog, do not edit this init script. # Set run_watchdog to 1 to start watchdog or 0 to disable it. run_watchdog=0 # Specify additional watchdog options here (see manpage). watchdog_options="" # Specify module to load watchdog_module="none" [ -e /etc/default/watchdog ] && . /etc/default/watchdog NAME=wd_keepalive DAEMON=/usr/sbin/wd_keepalive STOP_RETRY_SCHEDULE='TERM/10/forever/KILL/1' . /lib/lsb/init-functions case "$1" in start) if [ $run_watchdog = 1 ] then [ ${watchdog_module:-none} != "none" ] && /sbin/modprobe $watchdog_module echo -n "Starting watchdog keepalive daemon: " if start-stop-daemon --start --quiet \ --exec $DAEMON -- $watchdog_options then echo wd_keepalive. else echo fi fi ;; stop) if [ $run_watchdog = 1 ] then echo -n "Stopping watchdog keepalive daemon: " if start-stop-daemon --stop --quiet --pidfile /var/run/$NAME.pid \ --retry $STOP_RETRY_SCHEDULE then echo wd_keepalive. else echo fi fi ;; status) status_of_proc "$DAEMON" "$NAME" && exit 0 || exit $? ;; restart) $0 force-reload ;; force-reload) if [ $run_watchdog = 0 ]; then exit 0; fi echo -n "Restarting $NAME daemon." start-stop-daemon --stop --quiet --pidfile /var/run/$NAME.pid \ --retry $STOP_RETRY_SCHEDULE echo -n "." if start-stop-daemon --start --quiet --pidfile /var/run/$NAME.pid \ --exec $DAEMON -- $watchdog_options then echo "done." else echo fi ;; *) echo "Usage: /etc/init.d/wd_keepalive {start|stop|status|restart|force-reload}" exit 1 esac exit 0 watchdog-5.13/debian/changelog0000644000175000017500000006130112102721740016121 0ustar michaelmichaelwatchdog (5.13-1) unstable; urgency=low * New upstream version. * Added hardening build flags to Debian build. -- Michael Meskes Fri, 01 Feb 2013 12:15:10 +0100 watchdog (5.12-1) unstable; urgency=low * Fixed copyright notice.

This package was put together by Michael Meskes using the example driver given in the kernel. further Information: * see /usr/src/linux/Documentation/watchdog.txt Before you can use a kernel watchdog driver you have to make sure that the corresponding module is loaded. You can do that with "modprobe "or with adding the to the file "/etc/modules" to make sure it is always loaded during system startup. The software watchdog driver is called "softdog".

Tue Mar 5 09:11:34 MET 1996 - Fixed two bugs in watchdog.c reported (and patched) by Johannes Kroeger : Watchdog now tries to open /dev/watchdog before tugging its process ID away. - Released version 1.1 Thu May 23 14:20:59 MET DST 1996 - Added process table watch routine. - Process filemode before sleeping. - Released version 1.2 Thu May 30 13:00:44 MET DST 1996 - Watchdog now correctly shuts down the system if the process table is full Mon Jul 29 13:51:42 MET DST 1996 - Finally watchdog is able to shut down the system even if the process table remains full after killing all processes. - Released version 2.0 (this was a major overhaul) Fri Jan 31 13:39:43 MET 1997 - Disconnect deamon from console. - Close file descriptors 0, 1, 2 when compiled with USE_SYSLOG. - Cleaned up source code. - Write the softdog device between each check, since the increasing number of checks might cause problems otherise. - Test the system load average and reboot if it is too high. Thu Apr 3 11:14:07 MET DST 1997 - Fixed that nasty bug that caused the root partion to stay mounted during a soft reboot. - Fixed another bug that caused watchdog to kill itself during reboot before all the work was done. Wed Jun 4 20:16:23 CEST 1997 - Finally soft reboot works as advertised. - Tested NFS access in filemode. Fri Jun 6 22:55:16 CEST 1997 - Added ping mode: soft reboot is initiated if a given network/host does not answer. Wen Jun 11 09:25:36 CEST 1997 - Added file table check: reboot if file table overflow occurs.

Fri, 13 Mar 2009 12:26:40 +0100 - Made watchdog not close the watchdog device so early when trying a normal shutdown. This ensures a reset even if the system hangs while doing this. - Applied patch by Richard W.M. Jones to cleanup code base for gcc-4.4. Sun, 22 Mar 2009 14:33:21 +0100 - Some more bugfixes by me and Lon. - Released 5.6 Mon, 25 May 2009 02:46:32 +0200 - Allow config lines with arbitrary length. - Applied patch by Mike Frysinger to not use deprecated sys_siglist anymore. - Also removed configure test for sys_siglist. - Cleaned up includes, also courtesy of Mike Frysinger.

In the process also make sure that the daemons do not allocate memory once they are in daemon mode as a safeguard for systems running out of memory. Thu, 11 Feb 2010 14:50:39 +0100 - Decreased default interval from 10 seconds to just 1 because 10 is too much for some hardware especially embedded systems. Sat Mar 6 22:07:15 2010 +0100 - Applied two patches by Jon Ringle : - uclibc does not have index(), but strchr() is equivalent to index() according to the index man page - Fix compile with USE_SYSLOG disabled Patch by Jon Ringle Mon, 22 Mar 2010 15:24:02 +0100 - Released 5.8 Mon May 10 15:48:35 2010 +0200 - Applied patches by Martin Koegler : - Implementing a timeout for repair scripts - Fixing a few bugs.
