Solutions for NX Client version 2.0.0 and FreeNX 0.4.x and 0.5.0.

If you have problem connecting with new NX Client ver. 2.0.0, there are 2 patch, which working for me with NX Client ver. 2.0.0-93:

'fake cookie authentication problem':

Some new clients uses 1.4.0 as proto version. You have to make sure that 'fake cookie authentication' is working on the server. Look at nxnode and search for that string in 'node_startsession()' function and edit it.

For freenx 0.4.x nxnode in function 'node_startsession()' {{{ if [ "$ENABLE_1_5_0_BACKEND" = "1" -a "$clientproto" = "1.5.0" ] || [ "$ENABLE_1_5_0_BACKEND" = "1" -a "$clientproto" = "1.4.0" ]

fi }}}

For freenx 0.5.0 nxnode in function 'node_startsession()' {{{ if [ "$clientproto" = "1.5.0" ] || [ "$clientproto" = "1.4.0" ]

fi }}}

Pre 1.5 clients will face trouble in this case, though - but works for me (no users with old clients). As I see in comunnication with client ver. 2.0.0-93, it use 1.5.0 proto version, so this is for older 2.0.0 clients.

'Backingstore problem':

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 these 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.

Missing Color Definitions Cause Some Applications to Fail

After upgrading to the latest (xorg/testing 1:7.0.22), some applications will fail to start while using FreeNX (freenx 0.4.4+0.4.5-4) with the following error:

(application): Cannot allocate color (some color), such as:

xterm: Cannot allocate color green

Other applications will fail with similar errors.

The reason for this is that nxagent is looking for rgb.txt in /usr/X11R6/lib/X11, and it is not present.

Issuing a:

ln -s /etc/X11/rgb.txt /usr/X11R6/lib/X11/rgb.txt 

and restarting nxserver clears up the issue.
