hello,
if my understanding is correct, you want to export the graphical display of a remoter server on your local workstation.
telnet on the server, and :
export DISPLAY=your_workstation_ip_here:0.0
(eg export DISPLAY=192.168.1.1:0.0 if your wksta has 192.168.1.1 as IP).
Of course you must have a X server on your workstation (eg Exceed under Windows, and if your wkstation is Unix, juste type :
xhost +IP_from_remote_server_whose_display_is_exported, eg xhost +10.30.1.1)
then from the telnet windows launch the command of the application.
regards,
