First of all, thanks to Karl Runge and Ben Scott for responding with
some good ideas and thought-provoking questions and suggestions. I
haven't followed through on them all yet, but have found some
interesting new information.
It looks like the xterm session is still alive, although I just can't
find the pixels showing me what it's doing.
Here's the latest twist. I've got the connection through the firewall,
with the xterm running on the firewall accessing the server, and an FTP
running on the server to move some files back to my local system. The X
display just vanished, but the FTP is continuing to extend the output
file. So my present suspicion is that the xterm session thinks it's
fine, but I'm baffled about where it's putting the pixels on my local
display. FWIW, I've got RedHat 6.2 running all defaults, thus gnome as
my windowing shell. I'm not at all knowledgeable about this gooey stuff
(stuff, as pronounced S*** ! :-) so it may be something obvious, or very
simple, but it escapes me.
BTW, I'm not sure the environment was clearly stated or well understood
from my previous mail. Here is the sequence of commands that
established it (some names changed to protect the identities of innocent
Solaris boxes :-):
mybox# ssh [EMAIL PROTECTED]
firewall# setenv DISPLAY mybox:0
firewall# xterm -lf xterm.log
xterm# ssh -l my_account server.internal.net
server# ftp mybox.mydomain.com
this ran normally, for about 15MB worth, then a mouse movement or typing
into another window on mybox caused the xterm display to wink out of
this universe. The ftp has continued for the remainder of the transfer
(it was about halfway through), so it seems the glitch didn't affect the
xterm process on the firewall, at least not enough to abort the ssh
session on the server.
I'm baffled. Any good ideas about how I can find those pixels? (and
even better, convince them to reappear on my screen!)
THANKS!
