You need to tell your local machine that X connections from your remote
ones are allowed. This is done using "xhost".
Here's an example:
Your remote machine is remote.foobar.com, your local one local.foobar.com;
On your local machine, type "xhost + remote.foobar.com", on the remote
one, type "setenv DISPLAY local.foobar.com:0.0" (C Shell) or "export
DISPLAY=local.foobar.com:0.0" (Bourne Shell).
You should now be able to get what you wanted.
Warning: anybody can display a program on your own Display once you've
granted permissions with xhost.
Curiously, SUN workstations seem to refuse granting remote Linux
workstations such rights...
Apparently, the two machine's domains must be the same.
