X11 Forwarding and Remote Copy with SSH
Secure Shell (SSH)
Secure Shell encrypts all traffic, and provides a high level of protection against hacker attacks. It's intended as a (more) secure alternative to the likes of telnet, ftp, rsh, rlogin and rexec - and one which requires much less effort to set up than Kerberos or IPSEC currently do. Using the tunnelling feature, every non-secure application protocol like ftp can get made secure.
More Tips to the Secure Shell SSH can be found here.

Provided that your SSH server has X11 Forwarding set on and you have an X server running on your local machine, you can even display X11 through the SSH connection.
The SSH server will set your DISPLAY environment variable when connecting. It will be set to <servername>:<some_high_number>:0. The SSH server will then forward the X11 protocol to your local X server that you have specified in the settings (see More options... in the SSH Connection... option of the Settings menu). In this example we use TeraTerm to forward any X11 application.
