[FreeNX-kNX] Connection to freenx fails from nomachine client

[Anuradha Ratnaweera]

Hi all,

I have an up to date Debian unstable box which used to run freenx
1.4.x (my DEBs with a backported GLX patch is here
http://www.linux.lk/~anuradha/nx/) installed and was connecting to it
using the nomachine clients (both Linux and Windows) without any
problems.

Recently, after a major "dist upgrade", it wasn't possible to connect
to the server.  Without digging into the matter much, I upgraded to
1.5 using this apt source:

   http://debian.tu-bs.de/project/kanotix/unstable

and got hold of the latest client from Nomachine.  Still it's not
possible to connect.  After some time, the client reports that the
network connection was lost and here is the log at the client:


Info: Proxy running in client mode with pid '7266'.
Info: Connecting to remote host '10.2.2.1:5001'.

However, KDE starts up on the server.  Here is the output of
/var/log/nxserver.log :

I have tried enabling and disabling 1.5 backend and some tracing on
the server, but can't figure out the exact problem.  Any clues? 
Thanks in advance!
