Use XDMCP?

[M. Hornung]

It could be that your ipchains rule is out of order (i.e. some other rule
is grabbing the packet first).  Do you log dropped/denied datagrams?

Does the server have multiple network cards?  If so, let's see what
'netstat -ul' says about the different interfaces.  Maybe KDM is binding
to the wrong one.
