Re: [X2Go-User] Failure negotiating the session in stage '7'. Wrong version or invalid session authentication cookie.
Hey Roland,
I'm sorry but I'm quite busy right now. Following things to try:
Kill all sessions on your server. Use the root command to list all users sessions with: sudo x2golistsessions_root Delete all involved users .Xauthority files. If you've got hanging sessions left, manually execute x2goterminatesessions with the ID. Make the x2goserver logging level to debug in /etc/x2go/x2xgoserver.conf Reboot the machine.
Then open a new Master Session -> KDE or xterm, whatever.. Use the root command again to make sure it's known by the x2goserver. Then start the Shadow Session to the Master Session.
Include as many logfiles as possible into a new mail to the mailing list.

Kjell, thanks for your input so far. I was wondering if you have any other suggestions to try and track this pesky problem down?
regards
Roland

Have you tried to delete the .Xauthority File in the users Homefolder?
I have now.
On the client I log:
Loop: PANIC! The remote NX proxy closed the connection. Loop: PANIC! Failure negotiating the session in stage '7'. Loop: PANIC! Wrong version or invalid session authentication cookie.
On the server, the session log shows:

This makes me think. I port forward port 22 through the ADSL router (which has 192.168.1.1 as LAN ethernet address and the server has 192.168.1.3). Could this have something to do with the problem? What is port 30001 used for and should I allow that through the firewall? Surely port 22 should be enough?
I have also turned apparmor off, but it makes no difference.
thanks again
Roland
Please Try that first. Your log seems to be completely normal so far...
Do
you have a Desktop you can shadow to? I mean if there is no MasterSession opened, then you can't shadow it...

Wether it helps or not, it would be great to see the server side of this, so please post the corresponding entries of your /var/log/syslog after configuring the x2goserver for debugging(set it in /etc/x2go/x2goserver.conf).
Nevertheless, the only Cookies I can think used by x2go are the MIT magic cookies of X... maybe try to delete the .Xauthority of the user
to log in and retry...

I must have read every mailing list and other posts I could find on Google regarding this problem. Nowhere was anyone able to identify the actual cause and fix for this problem.
How can this be? Does anyone know where the X2Go developer(s) hang out?
thanks

I finally got around to trying this out tonight. There are no sessions running and I deleted all the .Xauthority file from the users' home directories. Then I rebooted.
Then open a new Master Session -> KDE or xterm, whatever..
I've have searched high and low. What is a new Master Session? I cannot find anything about it. I have logged in on the server console, but it makes not difference?
Use the root command again to make sure it's known by the x2goserver. Then start the Shadow Session to the Master Session. And of course, what is a Shadow Session?
I'm not trying to connect to a logged-in user at this stage, I just want to start a new X-session when I connect with x2goclient.
thanks again

Hey Roland,
I'm sorry but I'm quite busy right now. Following things to try:
Kill all sessions on your server. Use the root command to list all users sessions with: sudo x2golistsessions_root Delete all involved users .Xauthority files. If you've got hanging sessions left, manually execute x2goterminatesessions with the ID. Make the x2goserver logging level to debug in /etc/x2go/x2xgoserver.conf Reboot the machine. I finally got around to trying this out tonight. There are no sessions running and I deleted all the .Xauthority file from the users' home

I'm not trying to connect to a logged-in user at this stage, I just want to start a new X-session when I connect with x2goclient.

Hi Roland,
sorry to let you down on this, I'm still busy doing other stuff all the time.
The error you're getting seems to be related to your X-Server installation. The KDE part of the agent starting is completely normal, it's just about setting your color depth AFAIK.
Sorry about messing arround with Master and Shadow stuff... What I ment was this: When you're starting a GNOME session. You can just close the window when you're leaving the desktop. Then just start the GNOME session again once you want to come back. And you'll see the old one is still running and resumable.
There is another way to connect to an opened session, via the desktopsharing feature of x2go. But that seems unrelated...
It seems that you've messed up a part of your X or X configuration. This is acutally what stops your x2go client from really doing something:
check command message
X Error: BadWindow (invalid Window parameter) 3 Major opcode: 20 (X_GetProperty) Resource id: 0x4004bbc X Error: BadWindow (invalid Window parameter) 3 Major opcode: 15 (X_QueryTree) Resource id: 0x4004bbc
Try to find the problem related to this. It seems that your problem is not about x2go...

On the client, I connect to the server (client Ubuntu 12.10, server Ubuntu 12.04)
After displaying a message that a connection has been made, finally the error message pops up.

Things that I noticed above:
- The line "x2gostartagent 1440x900 adsl 16m-jpeg-9 unix-kde-depth_24 us pc105/us 1 D UNITY" seems to be asking for a KDE session despite the fact that I set Gnome as the session in my client config.

Session: Session aborted at 'Sun Jul 28 15:44:38 2013'.
What I do notice is the "refusing connection from 192.168.1.3". This is the ADSL router port, which forwards port 22 to the x2goserver.
In the following file
$ cat .x2go/C-roland-50-1375019027_stDGNOME_dp24/options
nx/nx,link=adsl,pack=16m-jpeg-9,limit=0,root=/home/roland/.x2go/C-roland-50-1375019027_stDGNOME_dp24,cache=8M,images=32M,type=unix-kde-depth_24,id=roland-50-1375019027_stDGNOME_dp24,cookie=72bfbf8ddda3489cab3462411822a417,errors=/tmp/.x2go-roland/session-C-roland-50-1375019027_stDGNOME_dp24.log,kbtype=pc105/us,geometry=1440x900,resize=0,fullscreen=0,accept=localhost,listen=30001,client=linux,menu=0:50
It seems that "accept=localhost" should be "accept=192.168.1.3", but the this file seems to be created for each session, so changing it, doesn't fix the problem.
I have added "192.168.1.3 localhost" to /etc/hosts as well as changed /etc/x2go/x2goagent.conf as follows:
X2GO_NXAGENT_DEFAULT_OPTIONS+=" -extension GLX -from 192.168.1.3"
This doesn't seem to change the session options in .x2go/C-roland-50-1375019027_stDGNOME_dp24/options
in /var/log/syslog, the following is logged:

I have had a detailed analysis with Mike Gabriel over on IRC as well, and it also lead to x2go not being able to connect to screen:50 for some reason.
