Yes, I do not export the DISPLAY explicitly when using ssh.  Rather, I
use the -X option.  However, that was not working, so I attempted to
explicitly set the DISPLAY environment variable.

It is strange, though, because I can export the DISPLAY from the
firewall BSD box to a RH6.2 linux box at my work.  Perhaps the fact
that the Debian box is on an internal network has something to do with
it?  I doubt it, but I figured I would mention that fact.

Any other ideas?
