I upgraded one of my machines to -stable from 16 August 2002, and
now I'm seeing some problems with X11 forwarding. The problem
appears to be with sshd and/or PAM on the upgraded machine.
When I simply slogin from another machine (strings) to the upgraded
machine (thin), X11 forwarding works OK:
strings$ slogin thin

Terminal type is xterm.
thin$ xterm [An xterm appears as expected.]
^Cthin$
But now if I "su" on the target machine, I can no longer run X
programs:
thin$ su
Password:
thin# xterm
X connection to localhost:10.0 broken (explicit kill or server shutdown).
thin#
But this works if I slogin from strings to a different machine
running -stable from around the end of June.
Back on thin (the upgraded machine), if I use "su -m" then it works.
The problem appears to be with the XAUTHORITY environment variable.
When I slogin to thin (the upgraded machine) XAUTHORITY does not get
set in my environment. When I slogin to the older machine, it does
get set, to something like "/tmp/ssh-sl53EABb/cookies".
Any suggestions? It looks like a bug to me.
John
