xdmcp remote xserver probelm

[Hendrik Sirges <hendriksirges@t-online.de>]

Hi. 

I got a problem setting up remote connections to a xdmcp server.
gdm is running on the remote-machine.
i also commented out the nolisten tcp lines in /etc/X11/xfs/config
and /etc/X11/xinit/xserverrc
i changed only one line in gdm.conf:
[xdmcp]
Enable=true

when i try to start a remote xsession it crashes:

_XSERVTransSocketOpenCOTSServer: Unable to open socket for inet6
_XSERVTransOpen: transport open failed for inet6/foo:1
_XSERVTransMakeAllCOTSServerListeners: failed to open listener for inet6
XDMCP warning: INET6 UDP socket creation failed

	snip
and exits with signal 11.

what  may went wrong? are there any services that should run to use 
remote xservers?

thanks in advance for you help.
