Using Net::SSH to Interact with Secure Shell

As you may know, SSH (or "Secure Shell") is a network protocol that allows you to exchange data with a remote host over an encrypted channel. It's most commonly used as an interactive shell with Linux and other UNIX-like systems. You may use it to log into a Web server and run a few commands to maintain your website. It can also do other things, though, such as transfer files and forward network connections.

Net::SSH is a way for Ruby to interact with SSH. Using this gem, you can connect to remote hosts, run commands, examine their output, transfer files, forward network connections, and do anything you would normally do with an SSH client.
