Bug#263449: kdm: still problems with remote login
Hi all,
with the recent kdm ist's still not possible to login from our X11-terminals.
On the terminals we run:
root 12042 1 1 2006 ? 14:29:21 /usr/bin/X11/Xorg -config /etc/X11/xorg.conf.ixxie :0 vt07 -dpi 100 -indirect up.dfn.de
with 'up.dfn.de' being the NFS-Server for the diskless terminals where an xdm
is running which provides the chooser for the terminals.
Everything works fine when selecting one of our sarge hosts from the chooser,
but it's not possible to log in to a recent etch system with kdm
3.5.5a.dfsg.1-5.
On my etch system named 'bunny' I run
root@bunny:~# ps -ef | grep bin/X
root 19960 19958 1 16:02 tty7 00:00:59 /usr/bin/X -br :0 vt7 -auth /var/run/xauth/A:0-hXsyh7
root@bunny:~# ps -ef | grep kdm
root 19958 1 0 16:02 ? 00:00:00 /usr/bin/kdm -config /var/run/kdm/kdmrc
root@bunny:~# grep -i serverargs /var/run/kdm/kdmrc
ServerArgsLocal=
#ServerArgsRemote=
The system 'bunny' shows up in the chooser window on the X-terminals but when
it is selected the X-cursor is shown for about 15 seconds and then the chooser
comes back instead of the login-window from 'bunny'.
The strace of the kdm-process on 'bunny' shows
select(26, [4 6 7 8 9 10 13 17], NULL, NULL, NULL) = 1 (in [8])

during those 15 seconds and after that it seems to reset itself:

close(11)
etc.
Does anyone have an idea what goes wrong here? I even removed the 'nolisten'
flag as you can see above so this seems to be a slightly different problem.
BTW: runnig 'X -query bunny' on the X-terminal works so I'm pretty shure
the setup on 'bunny' (kdmrc and Xaccess) is ok. But what's the difference
when using the chooser? There are no error-messages in /var/log/xdm.log on
the NFS/xdm/chooser-server so I'm a bit lost here.
Thanx for any hints what to try next...
Raoul
