John was referring to the configuration of sshd running on the target.

>From man sshd:

     no-X11-forwarding
          Forbids X11 forwarding when this key is used for authentication.
          Any X11 forward requests by the client will return an error.

If this is disallowed on the target I don't think he can do anything about it
if the firewall also disallows X connections back out. Unless he tries going
out over a non-standard port or some other such hack?

He may not be accepting connections or allowing inbound X clients but he is
not getting to that stage as indicated by the DISPLAY not set message. He
needs to sort out how he gets the X connection back from the remote server
before this becomes a consideration.

At least, this is my understanding of it! :-)

Cheers,

Ben.
