THANK YOU DARREN!

I've tried several things in my /etc/hosts file just to "assure" myself
that that wasn't the problem (one of the incarnations of that file was
exactly what Darren sent).  But, i'm now thinking that it may somehow be
related (or that name resolution may be somehow involved).

I added:
X11UseLocalhost no
to my sshd_config file and now everything works like a charm!

I'm still puzzled (so i'll note this for posterity).  The RH 8.0 install
is almoast identical to the old 6.2 install.  They share name servers, nis
servers (same nsswitch.conf too), etc.  Most of the filesystems are
shared.  sshd shares a configuration, etc.  The versions of ssh are the
same.  Yet, on the 8.0 side, I can't forward X11 (without specifying
X11UseLocalhost no) whereas on the 6.2 side, X11 forwarding works fine
(even without X11UseLocalhost no).

Many thanks to all who helped!,
Jim
