This primer explains how to connect to a unix cluster from the undergraduate teaching laboratory. It is possible to connect to UNIX/Linux computers remotely and run programs on the remote computer. This uses the XWindow system
Start XWindows on your computer (Start -> Programs -> Academic Applications -> Physics -> startxwin.bat).
Start a terminal Start -> Programs -> Academic Applications -> Physics -> XRvt)
You'll see a terminal as below, the white window. In the terminal ssh -x LOGON@MACHINENAME where you replace LOGON with your login and MACHINENAME with the machine your want to connect to.
Then you can start other commands on the remote machine and the window should be transmitted back to your terminal.
