These computer's must be networked together, and you need to be able to rsh or ssh into the second computer that is to run the program. For the example I am using gawk.wwc.edu to log into olympus.wwc.edu. I am going to log onto olympus and run matlab, which I can not run on gawk due to licensing issues. For security reasons, before the X Window System will display a window on the X screen, the computer which wants to display the window must be allow to display it. For now we are going to look at xhost .
Lets start by taking a look at the current xhost configuration.
Both of these names are the referring to my workstation. Okay, gawk is now already to show matlab when olympus runs it. My next step is to log into olympus, so that I can run matlab. I could use either rsh or ssh, but I choose to use ssh because it prevents people on my network sniffing for my password. So I type ssh , and log on as usual.
