In my wardrobe I have my noisy/fast server, to which I can connect via
the xdmcp protocol, either with my silent desktop machine or if im not
at home I can use ssh. It worked fluently for 6 months, but recently it
has become non-responsive and lagging. The network speed are 100Mbits
and I have killed all suspicius processes. I have even tried to restart
the server, but no luck.
Over time the problem seems to get worse. But I cannot see any processes
which has went loose.
