Re: [X2Go-User] Failure negotiating the session in stage '7'. Wrong version or invalid session authentication cookie.
by Kjell Otto 29 Jul '13

29 Jul '13

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. Greetings, Kjellski 2013/7/17 Roland Giesler <roland(a)giesler.za.net> > Kjell, thanks for your input so far.

'Connection failed sh: 1: Syntax error: "(" unexpected'
by Barnet Wagman 28 Jul '13

28 Jul '13

I received the following error message while attempting to connect: Connection failed sh: 1: Syntax error: "(" unexpected x2go had been working correctly. I assume that some shell script got corrupted. Does anyone know what shells script get calls when x2go connects? The error appears in a popup window in the x2go client. thanks PS my configuration is Server: Debian wheezy xfce4 x2goserver 4.0.1.3-0 Client: OS X 10.7.5 MacPorts x2goclient.app 4.0.1.0

Howto get full access with x2godesktopsharing
by Buddy Butterfly 27 Jul '13

27 Jul '13

Hi all, first, thanks a lot for the great product. I recently discovered and installed it and it worked! With the help of this forum I was also able to do desktopsharing. Two issues are open: 1. How to get full access with x2godesktopsharing? 2. Directory mapping is not working. I add a directory in the client config but can not see the directory in /tmp on the server. Thanks an best regards, Matt

X2Go and ssh forwarding
by Andreas Yankopolus 27 Jul '13

27 Jul '13

I'm trying to figure out how to use X2Go to connect with a machine at a private IP address via a public ssh server. I'm currently using ssh authentication forwarding to get to that machine: ssh -A -t andreas(a)public.ip.address ssh -A andreas(a)private.ip.address Thanks, Andreas

Session resume fails with AFS home directories
by Sebastian Flothow 26 Jul '13

26 Jul '13

Hi all, I've just set up a Debian 7 box with X2Go. It does work in that it is possible to start new sessions, however, resuming a previous session does not work, it always results in this message: "The remote proxy closed the connection while negotiating the session. This may be due to the wrong authentication credentials passed to the server." I suspect this is due to the fact that home directories are stored in AFS (for regular users, that is; when logging in as root, whose home directory is on a local ext4 FS, resume does work). Accessing AFS requires an AFS token in the user's name, obtaining this in turn requires a Kerberos ticket. PAM is set up to obtain both automatically on login, but I guess something goes wrong there during session resume. Is it possible to add custom commands to the X2Go login/resume procedure? It would be quite helpful if the client could run klist and tokens through the ssh session, and either log or display the output. Thanks, Sebastian

Sharing the display between two different users in x2go remove session (xhost + / DISPLAY variable)
by Nigra Truo 18 Jul '13

18 Jul '13

Hi, I am logged in as user Tom via x2go on my server. And in this session, I su to user Peter and want Peter to be able to use the same X session, i.e. display GUIs. When I try this, it fails. I use xeyes as a test. Error: Can't open display: unix:1077.0 I used already xhost (as Tom), to give everybody the right to use Tom's X display. xhost + access control disabled, clients can connect from any host when I do a echo $DISPLAY as user Tom, I get: :75 If I do the same as user Peter, I get: unix:1077.0 how can I get user Peter to be able to share the GUI / X remote session via x2go from Tom? How is x2go handling the DISPLAY variable? I think there lies the problem, not in the permissions. What circumstance makes me need to get this working: I cannot open a separate x2go session for user Peter, which would definitely be easier. I have tried this locally, on the server directly, and when I use xhost + and set the display variable of Peter to the same as Tom, he can use Tom's display and display xeyes. Any pointers would be appreciated! thanks Markus

X2go keyboard layout
by Nicolas Fabre 15 Jul '13

15 Jul '13

Hi all, I struggled a little bit with keyboard layouts in x2go. I found a way to enable numpad on a gnome 3.4.2 session (on debian Wheezy). I will try to make a traduction from my french version : go to system settings -> keyboard -> keyboard layout options -> Miscellaneous compatibility options -> numpad keys are always numerical (really not sure about this one). Ask if you need to. Cheers -- Nicolas FABRE

Failure negotiating the session in stage '7'. Wrong version or invalid session authentication cookie.

This error is most annoying to say the least, since no-where on the internet is an explaination of the cause nor the fix for it. Some people seem to have managed to get past it by luck. This is an Ubuntu 12.04 64bit server that had nxserver install. One day (probably after some update, but it was too long ago to undo of trace now) the nxclient just stopped working. I left it after many futile attempt to fix it. I have completely removed (purged) openssh-server and nxserver, nxnode and nxclient. Numerous times, apart from creating keys manually and more. So I though, let me switch to X2Go. And lo and behold, I get the same error. Strangely enough though, I can connect perfect to the server via SSH every time. What causes this and how does one fix this please? regards Roland
