\H{using-x-forwarding} Using \i{X11 forwarding} in SSH
The SSH protocol has the ability to securely forward X Window System
-applications over your encrypted SSH connection, so that you can run
-an application on the SSH server machine and have it put its windows
-up on your local machine without sending any X network traffic in
-the clear.
+\i{graphical applications} over your encrypted SSH connection, so that

In order to use this feature, you will need an X display server for
your Windows machine, such as Cygwin/X, X-Win32, or Exceed. This will probably
\H{using-port-forwarding} Using \i{port forwarding} in SSH
-The SSH protocol has the ability to forward arbitrary \i{network
-connection}s over your encrypted SSH connection, to avoid the network
-traffic being sent in clear. For example, you could use this to
-connect from your home computer to a \i{POP-3} server on a remote
-machine without your POP-3 password being visible to network
-sniffers.
