X Forwarding with Putty on Windows Intro to X ForwardingUnix machines have been able to run software on a remote machine and display the GUI locally for almost two decades. Linux and Mac OS X support X Forwarding with no extra software. Any terminal on Linux should do X Forwarding, Mac users need to run "Applications > Utilities > XTerm". In a command line terminal run "ssh -Y jdoe@compute.example.edu matlab" and you’ ...
