I tried that and it did not solve the problem, but you gave me an idea and it 
worked.

I put 'XAuthLocation <pathto_xauth>' in my ~/.ssh/config on the FreeBSD box 
and that fixed the problem for both Linux boxes; I can connect to either of 
them and run X apps.

I believe that if I do the same thing on each of the Linux boxes, I should be 
able to connect to the FreeBSD host and run X apps.

Also, instead of each user having to do the above modification, I will 
put 'XAuthLocation' in /etc/ssh/ssh_config (instead of sshd_config) globally 
and that should take care of this issue.


thank you for your help
