Solution:
------------------------------
Found a workaround for this problem. Seems like this problem is only in RHEL 4 and not RHEL 3.

nothing wrong with the ssh settings in /etc/ssh...

compare working RHEL3 setup and found that the config files are identical.

found that the following options in SSH will solve our remote X display problem in RHEL4

# ssh -X -A -l <username> <ipaddress>
-X Enables X11 forwarding.
-A Enables forwarding of the authentication agent connection.
# xclock &

Tested on older systems running RHEL 3, like the earlier version of OPEN-SSH does not require the -A and -X options for X11 forwarding to work.
openssh-server-3.6.1p2-33.30.3 ==> on RHEL3
openssh-server-3.9p1-8.RHEL4.9 ==> on RHEL4


I AM JUST GUESSING VIA THE ABOVE EXPERIMENTS, ANYONE KNOWS THE REASON BEHIND THIS?
