[FreeNX-kNX] problem connecting to server

[Barton L. Phillips]

I have downloaded the NoMachine client and the freenx server and 
installed them on my Ubuntu 5.10 machine. I have also installed the 
client on my RedHat 9 machine. When I try to connect to the server from 
either my Ubuntu machine via localhost or from my RedHat 9 machine I get 
the following error:

Info: Proxy running in client mode with pid '19461'.

When I look at the log files it looks like the connection happened 
without incident and then just closed:
