[FreeNX-kNX] FreeNX Failing on RDP Connections

[David Legg]

Hi All,

I have a 64-bit CentOS 5 installation where I previously had No Machine's 
freely available NX Server installed, successfully using X and RDP 
connections. I then decided to uninstall it and install FreeNX, because there 
is no connection limit. I definitely uninstalled the previous NX Server, node 
and client packages. The is FreeNX version 0.6.0-12, as-is from CentOS 
extras.

After an explicit restart of the nxserver via nxserver --restart the remote X 
connections worked fine, but I still can't connect to RDP Terminal Services 
connections through it. Yes I do know how this works, and how you have to put 
in your Linux machine's IP address and then the IP address of the Windows 
machine the NX Server accesses by proxy. I'm using client version 2.1.0-17 
from No Machine. The error messages I'm getting are these:

This is from the client window:

From the session file in .nx I'm getting:

broken (explicit kill or server shutdown).

In ~/.nx/errors I get:

Loop: WARNING! Disabling image cache with session 'session_rdp' and 
link 'adsl'.

This is with the logging set to 7 and SESSION_LOG_CLEAN=0.

I'm at a bit of a loss, as it looks as if something is silently failing and 
perhaps segfaulting somewhere. Are there some problems with FreeNX on a 
64-bit system, even with 32-bit compatibility libraries installed that anyone 
else has experienced like this? Does anyone else have this running OK? Is 
there any more logging I can do to find out what else might be going on here?

Thanks,

David
