[FreeNX-kNX] Problem connecting a freenx with debian etch/sid and possible solution

Fri Sep 22 17:08:44 UTC 2006

Well,

after spent a lot of time trying to understand what happens, I have found some 
point.

First of all it's a good idea modify the node.conf file to make nxserver to 
log more verbose.

After doing that, I have found a good way to find problems:
http://mail.kde.org/pipermail/freenx-knx/2005-February/000815.html

Login into your NX server and enable SSH X11 Forwarding.

# ssh -X user at yourserver

a) If your FreeNX is in /usr/NX do the following:

    # LD_LIBRARY_PATH="/usr/NX/lib" /usr/NX/bin/nxagent :1000

b) Else if its in /usr/bin or some other FHS structure do just:

   # nxagent :1000

after do that I found that:

leo at ranganathan:~$ LD_LIBRARY_PATH="/usr/NX/lib" /usr/NX/bin/nxagent :1000
/usr/NX/bin/nxagent: /usr/NX/lib/libpng12.so.0: no version information 
available (required by /usr/lib/libXcomp.so.1)
/usr/NX/bin/nxagent: /usr/NX/lib/libpng12.so.0: no version information 
available (required by /usr/lib/libXcompext.so.1)
Couldn't open RGB_DB '/usr/X11R6/lib/X11/rgb'
_XSERVTransmkdir: Owner of /tmp/.X11-unix should be set to root

NXAGENT - Version 1.5.0

Copyright (C) 2001, 2005 NoMachine.
See http://www.nomachine.com/ for more information.

Info: Agent running with pid '16499'.
/usr/NX/bin/nxagent: symbol lookup error: /usr/NX/bin/nxagent: undefined 
symbol: NXUnsetLibraryPath

so, the nxagent program has some problem with the link libraries. I have found 
that this function is on:

/usr/lib$ grep NXUnsetLibraryPath *
Binary file libX11-nx.so matches
Binary file libX11-nx.so.6 matches
Binary file libX11-nx.so.6.2 matches

so, I have recompiled the freenx and all the libs in the way that the xlibs 
are provided by x11proto-core-dev package, and not any by xlibs-dev (xfree)

After recompiled the packages and reinstalled, now all is working. The only 
issue that I have found is:

leo at ranganathan:/usr/lib$ nxagent :1000
Couldn't open RGB_DB '/usr/X11R6/lib/X11/rgb'
_XSERVTransmkdir: Owner of /tmp/.X11-unix should be set to root

But all is ok.

So, now I don't know that if it's a problem of the mixing packages betwend 
xorg 6 and xorg 7 in the etch/sid boxes or it's a problem of the packages 
that are compiled against xorg 6 and give some problem, etc.

Hope this could help to someone.

Regards,

Leo
