A small collection of base classes used for interacting with remote machines over ssh. With them, you can use AMQP (via Symphony) to run batch commands, execute templates as scripts, and perform any batch/remoting stuff you can think of without the need of separate client agents.

#Description

This is a small collection of base classes used for interacting with remote machines over ssh. With them, you can use AMQP (via Symphony) to run batch commands, execute templates as scripts, and perform any batch/remoting stuff you can think of without the need of a separate client agent.

These classes assume you have a user that can connect and login to remote machines using a password-less ssh keypair. They are not meant to be used directly. Subclass them!

See the rdoc for additional information and examples.

#Options

Symphony-ssh uses Configurability to determine behavior. The configuration is a YAML file.

symphony:
    ssh:
        path: /usr/bin/ssh
        user: root
        key: /path/to/a/private_key.rsa
        opts:
          - -e
          - none
          - -T
          - -x
          - -o
          - CheckHostIP=no'
          - -o
          - BatchMode=yes'
          - -o
          - StrictHostKeyChecking=no

NOTE: If you've upgrade from a version pre 0.2.0, the Configurability path has changed from symphony_ssh, to an ssh key under the symphony top level.

#path

The absolute path to the ssh binary.

#user

The default user to connect to remote hosts with. This can be changed per connection in the AMQP payload.

#key

An absolute path to a password-less ssh private key.

#opts

SSH client options, passed to the ssh binary on the command line. Note that the defaults have been tested fairly extensively, these are just exposed if you have very specific needs and you know what you're doing.

#Installation

gem install symphony-ssh

#Contributing

You can check out the current development source with Mercurial here, or via a mirror:

After checking out the source, run:

$ rake

This task will run the tests/specs and generate the API documentation.

If you use {rvm}[http://rvm.io/], entering the project directory will install any required development dependencies.
