[FreeNX-kNX] VMware Workstation 5 via NX ?

Mon Oct 3 19:16:36 UTC 2005

Hi,

I've installed the freenx 1.4.0 server on a gentoo installation and it 
works  well with the NX Client 1.4 under WinXP - tested with xterm and xarkeia.
But my main intention for setting up freenx was to run VMware remote, 
because the "speed" without NX-like compression is unbearable. But this 
doesn't work. After "Authentication completed" I get "Negotiating link 
parameters" message for some seconds, then "Could not yet establish the 
connection to the remote proxy..."
The "session" file on the server side looks like this:

----------
NXPROXY - Version 1.4.0

Copyright (C) 2001, 2004 NoMachine.
See http://www.nomachine.com/ for more information.

Info: Proxy running in server mode with pid '8793'.
Info: Waiting for connection from '10.130.5.1' on port '5001'.
grep: write error: Bad file descriptor
/opt/vmware/lib/lib/wrapper-gtk24.sh: line 94: 1: Bad file descriptor
Info: Aborting procedure due to signal '15'.
----------

VMware's wrapper-gtk24 script seems to cause of the problem, but what's 
wrong there? Any idea?
Thanks in advance!

Regards
Christoph
