I think mike meant this to go to the list as well as me (As I'm just a thread
contributer)...

I've seen this before I think (hope I'm right):

It's possible that sshd on the Sun box isn't configured to forward
X at all. There are two ways this can happen: in sshd.conf (or whatever
the blasted file is called) or possibly even in the binary build of sshd.

If, once logged-in on the box, you do
echo $DISPLAY
and it's blank, that is an indicator of at least the former and
possibly the latter as well.

It may be necessary to bypass ssh by doing something like
export DISPLAY=myclient
where 'myclient' is the box you log in from and then if you are
getting connection refused messages or authentication refused,
to try
xhost +name
where 'name' is the name of the sun box. Of course that presumes that your
X server is accepting external TCP connections and your client box isn't
firewalling it out.

Making ssh do the forwarding is MUCH easier if you can do it.
