FreeNX problem. nxagent fails to start

MegaSvensk · 10-21-2007, 08:39 AM

Hi,

I'm trying to get FreeNX working on my Ubuntu 7.10 so that I can access my desktop and files from work and other places. I did try VNC but it lacked a vital feature, namely audio.

I can't seem to get the FreeNX working though. When I attempt to connect (with NX client on Windows), I am connected and I pass the Authentication but then I get a "Session startup failed" error.

This is the log file:

Code:

I am guessing I have to change that unrecognized option but I have no idea where and to what.

Does anyone know how to get this working?

Thanks.

I found this after searching on Google some more:

Quote:

Thorsten Sandfuchs found some issues concerning backingstore. Problem arouse as you try to connect to a 0.5.0 installation with no 2.0.0 backend support and a 2.0.0-client. As Nomachine changed the behaviour of the backingstore-option. In 1.5.0-clients the client sends "always, when_requested" et all and freenx just passed this string to the nxagent-call. The new client now sends "backingstore=1" and the 1.5.0-nxagent issues a warning and an error with "no argument requiered for -bs" or with "Error: NX Agent exited with exit status 1.". You can read all his message here: Backingstore or 2.0.0-client and 1.5.0 backend and freenx-0.5

Look at nxnode and in function 'node_start_agent()' after this line

[ -n "$backingstore" ] && B="-bs $backingstore"

add this lines:

# backingstore = { "when_requested", "always", ... }
[ -n "$backingstore" -a "$ENABLE_2_0_0_BACKEND" != "1" -a "$backingstore" != "1" ] && B="-bs $backingstore"
# backingstore = 1 (new nxclient 2.0.0 doesn't send any strings in the option-string for backingstore anymore)
[ -n "$backingstore" -a "$ENABLE_2_0_0_BACKEND" != "1" -a "$backingstore" = "1" ] && B="+bs"
# backingstore = 1 and 2.0.0-Backend EXPERIMENTAL
[ -n "$backingstore" -a "$ENABLE_2_0_0_BACKEND" = "1" ] && B="-bs $backingstore"

This works using nxclient version 2.0.0-98.

This seems to be very similar to my problem, but I can't find the nxnode file that you're supposed to edit the lines into. I found node.conf, but that wasn't it because it didn't have the line I was supposed to look for.

Okay, I found the file and I added the lines but now it stops on a different error

Code:

Bump.

There must be someone who knows how to solve this.
