Recently, when I do "slogin -X server" (for one particular server,
not
all of them) the resulting session can't run any X11 utilities (e.g.
xterm) because there is no DISPLAY variable in the environment.
It used to work. I don't know what changed for sure.
Does anybody know what can cause this?
Try to run slogin with extra verbosity "on", e.g.:
slogin -X user@server -vvv"
Thanks for the suggestion.
The client is a Mac G5 running OS-X Leopard. The server is a Mac G4
running Debian Squeeze. It's not specific to this particular client.
I get the same problem from a client running Debian Squeeze.
Here's the output. I see it requesting X11 forwarding (near the end)
but I don't see anything specifically saying it was granted. Nor do I
see it being specifically refused. Fascinating...

PS: I recently ran "aptitude update && aptitude upgrade" on this
server and it picked up a couple of months worth of updates. I don't
*think* I had this problem before then...
