This does not seem to work on centos 6 - but it did work in centos 5. It works from a vnc session on the desktop machine, but does not work from the local desktop.

thats an awful practice.
instead, connect to the target machine with an SSH client that has
'x-forwarding' enabled (this is a checkbox in PuTTY or SecureCRT, and is
the -X flag on ssh command line). have your X 'server' running locally
(already running if you're on a unix workstation, I recommend Xming for
MS Windows desktops), and now any X application you launch via that ssh
session will open on your local desktop automagically.
