Good app. It's better than doing it by hand. Works great if you have an X server running too, which you found out. There are many apps that you can run from a server, but display the output on some other server. I do this often.
Example: SErver1 with no X display system. At a bash prompt I type "export DISPLAY=184.108.40.206:0.0"
At the 220.127.116.11 machine, I type xhost server1
Then on server machine, type the command of the app, TESTAPP &" and the display appears on my machine, and not the server's.
