Re: not getting login using xdmcp

I have a similar problem. This is with a SuSE 8.2 installation. I had
Mandrake 9.1 installed before and managed to get XDMCP working. Can't
get it working with SuSE however and I'm pulling my hair out!
I have nothing in my /var/log/messages nor /var/log/kdm.log files.
I'm using:
$ xwin -query sonslinux -from adefaria
X comes up but no login dialog box. XWin.log is attached.
Any help would be appreciated.
How many network interfaces do you have?
1
Find out the IP address of the interface that is actually
communicating with sonslinux and make sure to specify that IP address
in the -from parameter. If you give it the wrong IP, it will cause
the XDM serve to be unable to send messages back to XWin.exe
Retried it with my IP address. Same problem.
XDM: too many retransmissions
This is your key log message from XWin.log. The XDM support in
XWin.exe is generic to all X Servers, so you can google for this
message and try to find some help there. My guess is that you either
have a problem with the return address being incorrect (as I talk
about above), or one of the following:
1) You have not enabled an XDM server on your Linux machine followed
by a restart.
I have (an aside, my understanding is that XDMCP runs on port 177. I try
to telnet to port 177 and get connection refused. Guess this is not
good). As you probably know XDMCP is not enabled by default. I have
changed the config files to allow it (at least I think I have) and have
not only restarted kdm but have rebooted the machine to no avail.
2) You could also just not be running you linux machine at the correct
run level, which would cause the XDM server to not even be started.
Sonslinux sits right next to me. I am logged into a kde session right
now so I assume I'm at the proper run level.
3) You have not enabled remote XDMCP connections for the XDM server
that you are running (followed by a restart):

NOTE: The fact that the above link says "Mandrake" can be ignored...
it was originally written when Mandrake started defaulting XDMCP to
being disabled, which was closely followed by my realizing that almost
all distributions started doing this.
Yes. Let me read that and see what I find... (BTW this page answers my
soon to be next question of why I can't XDMCP to the Solaris box - Need
to use a font server! Thanks. BTW that XWin.log file may have been from
my attempt to XDMCP to the Solaris box. I've attached a new XWin.log).
Enabled XDMCP in /opt/kde3/share/config/kdm/kdmrc (SuSE 8.2 - it's not
listed in your table -perhaps you would like to update that).
Note I also found the following in /etc/X11/xdm/xdm-config:
! SECURITY: do not listen for XDMCP or Chooser requests
! Comment out this line if you want to manage X terminals with xdm
!
!DisplayManager.requestPort: 0
And as you can see I have commented that out. Both of these actions I
have done a few days ago and have since restarted kdm and even rebooted
sonslinux but the problem remains. This is why I'm pulling my hair out!
Additionally I made sure the following appears in
/opt/kde3/share/config/Xaccess and /etc/X11/xdm/Xaccess:
# The nicest way to run the chooser is to just ask it to broadcast
# requests to the network - that way new hosts show up automatically.
# Sometimes, however, the chooser can't figure out how to broadcast,
# so this may not work in all environments.
#
* CHOOSER BROADCAST #any indirect host can get a chooser
