Ok... From an xterm window on my local box, I do
$ssh -X <username>@<remotehost>
Then from the command prompt on the remote box, I type
$mtr -g www.cox.net
and instantly get the error
Gtk-WARNING **: cannot open display:
Explicitly setting $DISPLAY on the remote host causes the
same error, but it just takes a few seconds of cogitation, first.
Any ideas? Colin Watson says to remove '-nolisten tcp' from
the script that starts the local X. I'm going to try that now.
