How do I SSH into the math servers using MacOS X?
You need to run X11. It can be found in the “Utilities” folder under “Applications”. This application will load a terminal window. Type the following command in the terminal window: ssh -X [username]@[server name] or, to enable trusted X11 forwarding ssh -Y [username]@[server name] If you cannot find X11, it may not be installed on your machine. Please email helpdesk@math.purdue.edu and request that it be installed.
