SSHClient

Ruby SSH client for servers without exec requests support

Attention!!! This gem is research tool. Not recommended to use it in production environment.

Add this line to your application's Gemfile:

gem 'ssh_client'

And then execute:

$ bundle

Or install it yourself as:

$ gem install ssh_client

# Default config
SSHClient.configure do |conf|
  conf.hostname = 'example.com'
  conf.username = 'sample'
  conf.password = 'sample'
  conf.logger = Logger.new('log/my.log') # default log to STDOUT
  conf.read_timeout = 0.5 # default 0.3
  conf.raise_on_errors = true # raise exception if command write to STDERR
end

# Custom config
SSHClient.configure(:custom) do |conf|
  conf.hostname = '127.0.0.1'
end

Using connection instance

connection = SSHClient.connect

listener = connection.add_listener(:stdout) do |data|
  puts data
end

connection.exec 'hostname'
connection.remove_listener(listener)
connection.close

Using connection with custom config

connection = SSHClient.connect :custom

Pass hostname, username and password to connection

connection = SSHClient.connect hostname: 'example.com', username: 'sample', password: 'sample'

Multiply commands run with block. Connection closed after block execution

SSHClient.connect do
  run 'hostname'
  run 'uname -a'
  run 'cat /proc/cpuinfo | grep model'
end

Run command and return output

output = connection.exec! 'hostname'

output = connection.exec! do
  run 'hostname'
  run 'uname -a'
end
