Gooey VNC Moon Chicken on Trucks

So I don't forget:

On trucks, start a VNC server.
On Charybdis, use Chicken of the VNC to connect.

I happened to ssh into a machine called iveco, and vncserver started running on display 3 (thus the 5900 + 3). Enter an ssh password and there you have it - a gooey, gui connection :3  

This is the CS dept guide to VNC, though it does not use SSH tunneling.
