X11 Forwarding over SSH problem solved...
Ok I figured out my problem and now I feel stupid...
However in the interest of making the list archive complete so that other,
perhaps also stupid people, can fix this problem (should they be so stupid
as to create it), I will post the details (in the process revealing my
stupidity) :)
Turns out that there was an old entry in /etc/hosts for my machine name. It
listed a 192.160.x.x IP that used to be correct (when the box was on my
LAN). Apparently sshd fires up xauth, which checks the /etc/hosts
file...and in my case, added authorization for the wrong ip.
I tracked down this problem by running my sshd with the -d option, which
caused the client to spew a lot more info, one line being the offending
xauth command.
Thanks to everyone who offered help, especially
hservoma@wis02.ec.t.kanazawa-u.ac.jp, who suggested the debugging
parameters...
