[FreeNX-kNX] Free-nx 0.5.x for RHEL 4?

[David Parish]

Thanks. I'll give that a shot. I was able to get the 2.0 client and
the .4 backend working by making both of the changes suggested in the
troubleshooting guide:

Solutions for NX Clients versions 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" ]
    then
       # enable fake cookie authentication
       cookie=$proxy_cookie
 fi
For freenx 0.5.0 nxnode in function 'node_startsession()'

 if [ "$clientproto" = "1.5.0" ] || [ "$clientproto" = "1.4.0" ]
    then
       # enable fake cookie authentication
       cookie=$proxy_cookie
 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 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"
