Often I want to do some quick administration on a box of mine but don't really feel like running a VNC session (aka slow) just to do it. That's where forwarding X comes in real handy. Our prerequisites are 1) an understanding of what SSH and X Windows is/does 2) having those tools at your disposal, and 3) the remote machine must be able to forward X.

Say for instance on our remote machine there is an X application that we want to run on our local machine without needing VNC. Well, first, fire up the terminal. We want to SSH (secure shell) into our machine.
