SSH-n keresztüli X Windows-on

Unix 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’ll be running matlab on “compute.example.edu” but seeing it on your desktop.

Windows users need two pieces of software: an secure shell program (ssh) to establish the remote connection and an X Server to handle the local display.
