Setup Version 2.457.2.2: SSH X11 Forwarding McAfee

[Homayoun Yousefi'zadeh <hyousefi at yahoo dot com>]

Hello there,

I have two identical full installations of cygwin that came with setup 
version 2.457.2.2 on two XP machines. One machine is running Zonealarm
basic and the second McAfee security center. Both firewalls have 
properly assigned permissions to X11 programs and ssh. 

I use these machines to access Redhat servers using 
ssh -X and ssh -Y to enable X11 forwarding. I open an 
xterm from within a cygwin wmaker session and issue 
ssh commands. The machine with Zonealarm has no problem, 
i.e., it does login and function properly. The second 
machine with McAfee is able to login using ssh without 
any -X or -Y switch but the xterm hangs after I have 
entered the passwd when -X or -Y switches are included. 

I have performed another test scenario on the machine 
with McAfee. When I open an 
ssh session from putty and enable X11 tunneling, I can 
login and issue X commands from my putty session which 
results in executing those commands inside my 
wmaker session with no problem.    

Can somebody shed some light on how I can fix the 
problem with my XP machine running McAfee, i.e, 
I want to be able to run ssh command from within 
wmaker while enabling -X or -Y switches.

Regards,
HY
