Things have been working fine for several years, but suddenly, my mac

the x-server host [a sun machine] does not recognize the machine when
it attempts to pass back the x-window session.
Is anyone else having this problem?
NB: The reverse DNS is working fine.

As a general rule, it's far easier to use ssh's X11 forwarding
than to deal with xhosts and the $DISPLAY environment variable.

I agree with Bill. On Tiger you can issue ssh -Y username@system and everything should just work. On Panther it's ssh -X username@system. 'man ssh' for more information about those flags.

While I agree that this is best, it means that traffic will be encrypted, which might cause noticeable slowdown in performance. You can avoid this slowdown by using xauth to do user-level authentication.
