gdm-binary: Unable to connect to socket: hostname nor servname provided

[Laszlo Nagy]

  Hi All,

Do you have any idea what is the problem with my settings? gdm places 
this message in /var/log/messages:

Nov 20 12:19:05 cassiopeia gdm-binary[1167]: ERROR: Unable to connect to 
socket: hostname nor servname provided, or not known aborting...

The local X server starts, but gdm is not accepting connections on 
TCP/177. This is the problem, because I want many clients connect to 
this computer with xdmcp.

My ports tree was first downloaded via "portsnap fetch" three days ago. 
All ports have been compiled from this ports tree.  My 
/usr/local/etc/gdm/custom.conf file has these modifications:

<snip>
[security]
DisallowTCP=false

[xdmcp]
Enable=true
</snip>

Here is some more information:
