Thanks for the replies.
Maybe I should let you know what I have already tried:
I have gone through xdm-config with a fine toothed comb and made sure that all of the settings are correct (as per LTSP docs).
I have removed and re-generated MIT-COOKIES...
I have deleted all users .Xauthority files. Then I re-initialized them.
I have tried to run "xhost +" to allow all hosts to connect to the
server....but xhost errors out with 'can't open display ""'...so I make
sure that $DISPLAY holds a value....export DISPLAY="host:0"....now the
error is 'can't open display "host:0"'. I can't get xhost to do anything
but error out. I have tried 10 or 15 different $DISPLAY values...no
go....xhost does nothing.
xhost is not the problem. it won't work, until you have a display that is working properly. In your case, you don't.
This for sure isn't the problem. if it were, you wouldn't even getI have made sure that xdm-config has 'DisplayManager.requestPort: 0' commented out. And 'DisplayManager*authorize: false'
a login prompt.
The problem IS that I DON'T get a login prompt. I get the classic X-windows gray crosshatch screen with the X mouse cursor....at the same time if I examine the xdm.log, I can see it filling up with the error messages:
Xlib: connection to "mike.bowes.com:1.0" refused by server Xlib: Invalid MIT-MAGIC-COOKIE-1 key
This message repeats for 10 tries then gives up and disables my display until I restart xdm.
Disk space is not an issue...I have 20GB free.Again, this isn't the problem, or you wouldn't have a login prompt.
I have made sure that xdm is starting from inittab with:
x:5:respawn:/usr/X11R6/bin/xdm -nodaemon
Again, I DON'T get a login prompt.
I am about at the end of my rope with this! It was working PERFECTLY for
3 months until this past Friday....WTF??
What I would do at this point, is add some debugging lines to the /etc/X11/xdm/Xsession file.
Something as simple as this:
echo "Hello, made it to Xsession" >/tmp/xsession.out
Put that line way up near the top of the Xsession file. Then, after attempting to log in, and failing, go look at /tmp/xsession.out
If you have a /tmp/xsession.out file, you'll know that the Xsession
script is at least executing. If not, then you'll know that you
need to figure out WHY it isn't executing.
OK. Just to be sure, I did as you suggest and added some debug to Xsession. The /tmp file did NOT get created. So Xsession is not being executed. (I already suspected this since I was not getting a login).
This is part of my 'Divide and conquer' technique for solving
problems like this.
Yes. This an effective technique. Unfortunately, I don't know enough about X to be able to backtrack to the problem. I don't know what gets called on the server side when an X session is started (other than xdm itself and now Xsession from your comment above).
Keep splitting the problem in half, and determine what is working and what is NOT working. It will help you get to the root of the problem much quicker.
If the /tmp/xsession.out file does exist, then add more debugging lines to the Xsession script. See if you can figure out how far it is making it through the script.
If it calls any other scripts, do the same thing. you will get to the cause, and then be able to fix it.

------Previous Post------------------- Hi,
I have been running LTSP on a server with 7 clients for about 3 months with no problems.
Today a client machine booted, contacted the server, did start_ws and.....The X screen comes up, then disappears, then comes up, then disappears...in an endless cycle. So, I now try another client...same thing...grrrrrr.
The xdm log says:
Xlib: connection to "mike.bowes.com:1.0" refused by server Xlib: Invalid MIT-MAGIC-COOKIE-1 key Xlib: connection to "mike.bowes.com:1.0" refused by server Xlib: Invalid MIT-MAGIC-COOKIE-1 key xdm error (pid 4572): server open failed for mike.bowes.com:1, giving up xdm error (pid 4559): Display mike.bowes.com:1 cannot be opened xdm error (pid 4559): Display mike.bowes.com:1 is being disabled xdm error (pid 4559): Unknown session exit code 2816 from process 4663 xdm error (pid 4559): Unknown session exit code 2816 from process 4677 xdm error (pid 4559): Unknown session exit code 2816 from process 4691 xdm error (pid 4559): Unknown session exit code 2816 from process 4705 xdm error (pid 4559): Unknown session exit code 2816 from process 4719 xdm error (pid 4733): fatal IO error 32 (Broken pipe) xdm error (pid 4559): Unknown session exit code 2816 from process 4748 xdm error (pid 4559): Unknown session exit code 2816 from process 4762 xdm error (pid 4776): fatal IO error 32 (Broken pipe)
Please, any help would be greatly appreciated.
Thanks
Mike
