SSH

It allows you to connect to a command line interface on your server in a secure way. If you are familiar with telnet, it is the same thing but with encryption for security.

In addition to the command line interface, SSH has the ability to tunnel other protocols through its encrypted connection. This is useful for encrypting insecure protocols (Like VNC) and for gaining access to services blocked by a firewall.

Unix platforms include SSH clients by default. If you need an SSH client for Windows, we suggest using the free SSH client from the Cygwin project.
