22. How do I use X-Windows to view graphical applications?

bohrg1/storage

 1. desktop> ssh -X bohrg1.man.ac.uk -l <username>

        -- "-X" not always required, depends on config on your desktop machine,
           but will do no harm;

        -- NOT "-x";

 2. bohrg1> ssh storage

 3. storage>xterm &

     -- do not "export DISPLAY=..." or "setenv DISPLAY ..."
     -- do not su at any stage

bohrg3/dominion1

 -- not at the moment, to come...
