The telnet session doesn't have the correct xauth credentials to connect
to the Xserver. In your ssh session, type "xauth list" to find out the
key matching your $DISPLAY, then in the telnet session, use "xauth add"
to add the credentials.
Typically you'd use the "extract" and "merge" options in a pipeline,
something like:
"xauth nextract - $DISPLAY | ssh somehost xauth nmerge -"
Check the xauth man page for details.
Is it possible to ssh into the second box as well? That would save you
some trouble as ssh will do all of the $DISPLAY setting for you.

Good judgement comes with experience. Unfortunately, the experience
usually comes from bad judgement.
