That got me thinking...Looking at a third server (the same i386 Debian Squeeze machine I was using as a "client" in the previous reply) I *can* "slogin -X" and get an X session.
On both the successful server and the failing server, the version of "openssh-server" is "1:5.5p1-6+squeeze2".
So that's no help, either. Very curious... Rick
