## Building/running ssh server in debug mode
clone the openssh server from `https://github.com/openssh/openssh-portable`
```sh
brew install openssl
/usr/local/Cellar/openssl@3/3.1.0/bin/openssl
autoreconf
./configure --with-ssl-dir=/usr/local/Cellar/openssl@3/3.1.0/ --with-audit=debug --enable-debug CPPFLAGS="-DDEBUG -DPACKET_DEBUG" CFLAGS="-g -O0"
make
```
To run server in debug mode:
```sh
echo '#' > /tmp/sshd_config
ssh-keygen -t rsa -f /tmp/ssh_host_rsa_key
# /Users/boga/Work/OSS/NetSSH/openssh-portable/sshd -p 2222 -D -d -d -d -e -f /tmp/sshd_config
/Users/boga/Work/OSS/NetSSH/openssh-portable/sshd -p 2222 -D -d -d -d -e -f /tmp/sshd_config -h /tmp/ssh_host_rsa_key

# Net::SSH 7.x
* Docs: http://net-ssh.github.io/net-ssh
* Issues: https://github.com/net-ssh/net-ssh/issues
* Codes: https://github.com/net-ssh/net-ssh
* Email: net-ssh@solutious.com
*As of v2.6.4, all gem releases are signed. See [INSTALL](#install).*
## DESCRIPTION:
Net::SSH is a pure-Ruby implementation of the SSH2 client protocol.
It allows you to write programs that invoke and interact with processes on remote servers, via SSH2.
## FEATURES:
* Execute processes on remote servers and capture their output
* Run multiple processes in parallel over a single SSH connection
* Support for SSH subsystems
* Forward local and remote ports via an SSH connection
## Supported Algorithms
Net::SSH 6.0 disables by default the usage of weak algorithms.
We strongly recommend that you install a servers's version that supports the latest algorithms.
It is possible to return to the previous behavior by adding the option : `append_all_supported_algorithms: true`
Unsecure algoritms will definitely be removed in Net::SSH 8.*.

## SYNOPSIS:
In a nutshell:
```ruby
require 'net/ssh'
Net::SSH.start('host', 'user', password: "password") do |ssh|
# capture all stderr and stdout output from a remote process
output = ssh.exec!("hostname")
puts output
# capture only stdout matching a particular pattern
stdout = ""
ssh.exec!("ls -l /home/jamis") do |channel, stream, data|
stdout << data if stream == :stdout && /foo/.match(data)
end
puts stdout
# run multiple processes in parallel to completion
ssh.exec "sed ..."
ssh.exec "awk ..."
ssh.exec "rm -rf ..."
ssh.loop
# open a new channel and configure a minimal set of callbacks, then run
# the event loop until the channel finishes (closes)
channel = ssh.open_channel do |ch|
ch.exec "/usr/local/bin/ruby /path/to/file.rb" do |ch, success|
raise "could not execute command" unless success
# "on_data" is called when the process writes something to stdout
ch.on_data do |c, data|
$stdout.print data
end
# "on_extended_data" is called when the process writes something to stderr
ch.on_extended_data do |c, type, data|
$stderr.print data
end
ch.on_close { puts "done!" }
end
end
channel.wait
# forward connections on local port 1234 to port 80 of www.capify.org
ssh.forward.local(1234, "www.capify.org", 80)
ssh.loop { true }
end
```
See Net::SSH for more documentation, and links to further information.
## REQUIREMENTS:
The only requirement you might be missing is the OpenSSL bindings for Ruby with a version greather than `1.0.1`.
These are built by default on most platforms, but you can verify that they're built and installed on your system by running the following command line:
```sh
ruby -ropenssl -e 'puts OpenSSL::OPENSSL_VERSION'
```
If that spits out something like `OpenSSL 1.0.1 14 Mar 2012`, then you're set.
If you get an error, then you'll need to see about rebuilding ruby with OpenSSL support,
or (if your platform supports it) installing the OpenSSL bindings separately.
## INSTALL:
```sh
gem install net-ssh # might need sudo privileges
```
NOTE: If you are running on jruby on windows you need to install `jruby-pageant` manually
(gemspec doesn't allow for platform specific dependencies at gem installation time).
However, in order to be sure the code you're installing hasn't been tampered with,
it's recommended that you verify the [signature](http://docs.rubygems.org/read/chapter/21).
To do this, you need to add my public key as a trusted certificate (you only need to do this once):
```sh
# Add the public key as a trusted certificate
# (You only need to do this once)
curl -O https://raw.githubusercontent.com/net-ssh/net-ssh/master/net-ssh-public_cert.pem
gem cert --add net-ssh-public_cert.pem
```
Then, when install the gem, do so with high security:
```sh
gem install net-ssh -P HighSecurity
```
If you don't add the public key, you'll see an error like "Couldn't verify data signature".
If you're still having trouble let me know and I'll give you a hand.
For ed25519 public key auth support your bundle file should contain `ed25519`, `bcrypt_pbkdf` dependencies.
```sh
gem install ed25519
gem install bcrypt_pbkdf
```
For curve25519-sha256 kex exchange support your bundle file should contain `x25519` dependency.
## RUBY SUPPORT
* See [net-ssh.gemspec](https://github.com/net-ssh/net-ssh/blob/master/net-ssh.gemspec) for current versions ruby requirements
## RUNNING TESTS
If you want to run the tests or use any of the Rake tasks, you'll need Mocha and
other dependencies listed in Gemfile
Run the test suite from the net-ssh directory with the following command:
```sh
bundle exec rake test
```
NOTE : you can run test on all ruby versions with docker :
```
docker-compose up --build
```
Run a single test file like this:
```sh
ruby -Ilib -Itest test/transport/test_server_version.rb
```
To run integration tests see [here](test/integration/README.md)
### BUILDING GEM
```sh
rake build
```
### GEM SIGNING (for maintainers)
If you have the net-ssh private signing key, you will be able to create signed release builds. Make sure the private key path matches the `signing_key` path set in `net-ssh.gemspec` and tell rake to sign the gem by setting the `NET_SSH_BUILDGEM_SIGNED` flag:
```sh
NET_SSH_BUILDGEM_SIGNED=true rake build
```
For time to time, the public certificate associated to the private key needs to be renewed. You can do this with the following command:
```sh
gem cert --build netssh@solutious.com --private-key path/2/net-ssh-private_key.pem
mv gem-public_cert.pem net-ssh-public_cert.pem
gem cert --add net-ssh-public_cert.pem
```
or `rake cert:update_public_when_expired`

# Net::SSH is a library for interacting, programmatically, with remote
# processes via the SSH2 protocol. Sessions are always initiated via
# Net::SSH.start. From there, a program interacts with the new SSH session
# via the convenience methods on Net::SSH::Connection::Session, by opening
# and interacting with new channels (Net::SSH::Connection:Session#open_channel
# and Net::SSH::Connection::Channel), or by forwarding local and/or
# remote ports through the connection (Net::SSH::Service::Forward).
#
# The SSH protocol is very event-oriented. Requests are sent from the client
# to the server, and are answered asynchronously. This gives great flexibility
# (since clients can have multiple requests pending at a time), but it also
# adds complexity. Net::SSH tries to manage this complexity by providing
# some simpler methods of synchronous communication (see Net::SSH::Connection::Session#exec!).
#
# In general, though, and if you want to do anything more complicated than
# simply executing commands and capturing their output, you'll need to use
# channels (Net::SSH::Connection::Channel) to build state machines that are
# executed while the event loop runs (Net::SSH::Connection::Session#loop).
#
# Net::SSH::Connection::Session and Net::SSH::Connection::Channel have more
# information about this technique.
#

#
# This method accepts the following options (all are optional):
#
# * :auth_methods => an array of authentication methods to try
# * :bind_address => the IP address on the connecting machine to use in
# establishing connection. (:bind_address is discarded if :proxy
# is set.)
# * :check_host_ip => Also ckeck IP address when connecting to remote host.
# Defaults to +true+.
# * :compression => the compression algorithm to use, or +true+ to use
# whatever is supported.
# * :compression_level => the compression level to use when sending data
# * :config => set to +true+ to load the default OpenSSH config files
# (~/.ssh/config, /etc/ssh_config), or to +false+ to not load them, or to
# a file-name (or array of file-names) to load those specific configuration
# files. Defaults to +true+.
# * :encryption => the encryption cipher (or ciphers) to use
# * :forward_agent => set to true if you want the SSH agent connection to
# be forwarded
# * :known_hosts => a custom object holding known hosts records.
# It must implement #search_for and `add` in a similiar manner as KnownHosts.
# * :global_known_hosts_file => the location of the global known hosts
# file. Set to an array if you want to specify multiple global known
# hosts files. Defaults to %w(/etc/ssh/ssh_known_hosts /etc/ssh/ssh_known_hosts2).

# * :host_key => the host key algorithm (or algorithms) to use
# * :host_key_alias => the host name to use when looking up or adding a
# host to a known_hosts dictionary file
# * :host_name => the real host name or IP to log into. This is used
# instead of the +host+ parameter, and is primarily only useful when
# specified in an SSH configuration file. It lets you specify an
# "alias", similarly to adding an entry in /etc/hosts but without needing
# to modify /etc/hosts.
# * :keepalive => set to +true+ to send a keepalive packet to the SSH server
# when there's no traffic between the SSH server and Net::SSH client for
# the keepalive_interval seconds. Defaults to +false+.
# * :keepalive_interval => the interval seconds for keepalive.
# Defaults to +300+ seconds.
# * :keepalive_maxcount => the maximun number of keepalive packet miss allowed.
# Defaults to 3
# * :kex => the key exchange algorithm (or algorithms) to use
# * :keys => an array of file names of private keys to use for publickey
# and hostbased authentication
# * :keycerts => an array of file names of key certificates to use
# with publickey authentication
# * :keycert_data => an array of strings, which each element of the array
# being a key certificate to use with publickey authentication
# * :key_data => an array of strings, with each element of the array being
# a raw private key in PEM format.
# * :keys_only => set to +true+ to use only private keys from +keys+ and
# +key_data+ parameters, even if ssh-agent offers more identities. This
# option is intended for situations where ssh-agent offers many different
# identites.
# * :logger => the logger instance to use when logging
# * :max_pkt_size => maximum size we tell the other side that is supported per
# packet. Default is 0x8000 (32768 bytes). Increase to 0x10000 (65536 bytes)
# for better performance if your SSH server supports it (most do).
# * :max_win_size => maximum size we tell the other side that is supported for
# the window.
# * :non_interactive => set to true if your app is non interactive and prefers
# authentication failure vs password prompt. Non-interactive applications
# should set it to true to prefer failing a password/etc auth methods vs.
# asking for password.
# * :paranoid => deprecated alias for :verify_host_key
# * :passphrase => the passphrase to use when loading a private key (default
# is +nil+, for no passphrase)
# * :password => the password to use to login
# * :port => the port to use when connecting to the remote host
# * :properties => a hash of key/value pairs to add to the new connection's
# properties (see Net::SSH::Connection::Session#properties)
# * :proxy => a proxy instance (see Proxy) to use when connecting
# * :pubkey_algorithms => the public key authentication algorithms to use for
# this connection. Valid values are 'rsa-sha2-256-cert-v01@openssh.com',
# 'ssh-rsa-cert-v01@openssh.com', 'rsa-sha2-256', 'ssh-rsa'. Currently, this
# option is only used for RSA public key authentication and ignored for other
# types.
# * :rekey_blocks_limit => the max number of blocks to process before rekeying
# * :rekey_limit => the max number of bytes to process before rekeying
# * :rekey_packet_limit => the max number of packets to process before rekeying
# * :send_env => an array of local environment variable names to export to the
# remote environment. Names may be given as String or Regexp.
# * :set_env => a hash of environment variable names and values to set to the
# remote environment. Override the ones if specified in +send_env+.
# * :timeout => how long to wait for the initial connection to be made
# * :user => the user name to log in as; this overrides the +user+
# parameter, and is primarily only useful when provided via an SSH
# configuration file.
# * :remote_user => used for substitution into the '%r' part of a ProxyCommand
# * :user_known_hosts_file => the location of the user known hosts file.
# Set to an array to specify multiple user known hosts files.
# Defaults to %w(~/.ssh/known_hosts ~/.ssh/known_hosts2).
# * :use_agent => Set false to disable the use of ssh-agent. Defaults to
# true
# * :identity_agent => the path to the ssh-agent's UNIX socket
# * :verbose => how verbose to be (Logger verbosity constants, Logger::DEBUG
# is very verbose, Logger::FATAL is all but silent). Logger::FATAL is the
# default. The symbols :debug, :info, :warn, :error, and :fatal are also
# supported and are translated to the corresponding Logger constant.

# algorithms by net-ssh. Was the default behaviour until 2.10
# * :number_of_password_prompts => Number of prompts for the password
# authentication method defaults to 3 set to 0 to disable prompt for
# password auth method
# * :password_prompt => a custom prompt object with ask method. See Net::SSH::Prompt
#
# * :agent_socket_factory => enables the user to pass a lambda/block that will serve as the socket factory
# Net::SSH.start(host,user,agent_socket_factory: ->{ UNIXSocket.open('/foo/bar') })
# example: ->{ UNIXSocket.open('/foo/bar')}
# * :verify_host_key => specify how strict host-key verification should be.
# In order of increasing strictness:
# * :never (very insecure) ::Net::SSH::Verifiers::Never
# * :accept_new_or_local_tunnel (insecure) ::Net::SSH::Verifiers::AcceptNewOrLocalTunnel
# * :accept_new (insecure) ::Net::SSH::Verifiers::AcceptNew
# * :always (secure) ::Net::SSH::Verifiers::Always
# You can also provide an own Object which responds to +verify+. The argument
# given to +verify+ is a hash consisting of the +:key+, the +:key_blob+,
# the +:fingerprint+ and the +:session+. Returning true accepts the host key,
# returning false declines it and closes the connection.
# * :fingerprint_hash => 'MD5' or 'SHA256', defaults to 'SHA256'
# If +user+ parameter is nil it defaults to USER from ssh_config, or
# local username

# Net::SSH::Buffer is a flexible class for building and parsing binary
# data packets. It provides a stream-like interface for sequentially
# reading data items from the buffer, as well as a useful helper method
# for building binary packets given a signature.
#
# Writing to a buffer always appends to the end, regardless of where the
# read cursor is. Reading, on the other hand, always begins at the first
# byte of the buffer and increments the read cursor, with subsequent reads
# taking up where the last left off.
#
# As a consumer of the Net::SSH library, you will rarely come into contact
# with these buffer objects directly, but it could happen. Also, if you
# are ever implementing a protocol on top of SSH (e.g. SFTP), this buffer
# class can be quite handy.
class Buffer
# This is a convenience method for creating and populating a new buffer
# from a single command. The arguments must be even in length, with the
# first of each pair of arguments being a symbol naming the type of the
# data that follows. If the type is :raw, the value is written directly
# to the hash.
#
# b = Buffer.from(:byte, 1, :string, "hello", :raw, "\1\2\3\4")
# #-> "\1\0\0\0\5hello\1\2\3\4"
#
# The supported data types are:
#
# * :raw => write the next value verbatim (#write)
# * :int64 => write an 8-byte integer (#write_int64)
# * :long => write a 4-byte integer (#write_long)
# * :byte => write a single byte (#write_byte)
# * :string => write a 4-byte length followed by character data (#write_string)
# * :mstring => same as string, but caller cannot resuse the string, avoids potential duplication (#write_moved)
# * :bool => write a single byte, interpreted as a boolean (#write_bool)
# * :bignum => write an SSH-encoded bignum (#write_bignum)
# * :key => write an SSH-encoded key value (#write_key)
#
# Any of these, except for :raw, accepts an Array argument, to make it
# easier to write multiple values of the same type in a briefer manner.

# This module is used to extend sockets and other IO objects, to allow
# them to be buffered for both read and write. This abstraction makes it
# quite easy to write a select-based event loop
# (see Net::SSH::Connection::Session#listen_to).
#
# The general idea is that instead of calling #read directly on an IO that
# has been extended with this module, you call #fill (to add pending input
# to the internal read buffer), and then #read_available (to read from that
# buffer). Likewise, you don't call #write directly, you call #enqueue to
# add data to the write buffer, and then #send_pending or #wait_for_pending_sends
# to actually send the data across the wire.
#
# In this way you can easily use the object as an argument to IO.select,
# calling #fill when it is available for read, or #send_pending when it is
# available for write, and then call #enqueue and #read_available during
# the idle times.
