Folder sharing does not work with x2goclient
by Emanuele Rocca 27 Nov '14

27 Nov '14

Hi list, While folder sharing works fine using pyhoca-cli, it does not work at all with x2goclient. This is what sshd says on the client side when trying to "share" a folder from the gui: May 8 13:55:43 uranus sshd[23908]: Connection from 127.0.0.1 port 51821 May 8 13:55:43 uranus sshd[23908]: Connection closed by 127.0.0.1 [preauth] mount's output on the server side does not show anything interesting. I am running Ubuntu precise (12.04), both on the client and the server. Do you have any hints on how to debug this further? Installed packages: ii cups-x2go 3.0.0.3-0~54~oneiric1 X2GO printer for CUPS ii python-x2go 0.1.1.9-0-0~612~oneiric1 Python module for X2go client support ii x2goagent 2:3.5.0.11-0~220~oneiric1 X2Go agent ii x2goclient 3.99.0.6-0~144~oneiric1 X2Go Client application (Qt4) ii x2gognomebindings 2.0.1.4-0~53~oneiric1 Description: x2gognomebindings (GNOME mimetypes for X2go) ii x2goserver 3.1.0.0-0~477~oneiric1 X2Go server daemon scripts ii x2goserver-compat 3.1.0.0-0~477~oneiric1 X2Go server daemon scripts (backwards compatitbity to old client versions) ii x2goserver-extensions 3.1.0.0-0~477~oneiric1 X2Go server daemon scripts (extensions) ii x2goserver-fmbindings 3.1.0.0-0~477~oneiric1 Generic (freedesktop-based) file manager bindings for X2Go ii x2goserver-printing 3.1.0.0-0~477~oneiric1 X2Go server daemon scripts (printing) ii x2goserver-pyhoca 3.1.0.0-0~477~oneiric1 X2Go server daemon scripts (add-ons for pyhoca client) ii x2goserver-xsession 3.1.0.0-0~477~oneiric1 X2Go server daemon scripts (Xsession runner) ii pyhoca-cli 0.1.4.2-0~108~oneiric1 A command line X2go client written in Python ii pyhoca-gui 0.1.0.10-0~487~oneiric1 A graphical X2go client written in (wx)Python ii x2goserver-pyhoca 3.1.0.0-0~477~oneiric1 X2Go server daemon scripts (add-ons for pyhoca client) Conf file: [20120503160857309] speed=3 pack=16m-jpeg quality=9 fstunnel=true export="/media:1;" iconvto=UTF-8 iconvfrom=ISO8859-1 useiconv=false fullscreen=false width=1024 multidisp=false display=1 height=768 dpi=96 setdpi=false xinerama=false usekbd=true layout=us type=pc105/us sound=true soundsystem=pulse startsoundsystem=true soundtunnel=true defsndport=true sndport=4713 print=true name=xxx icon=:icons/128x128/x2gosession.png host=host.example.org user=username key= sshport=22 autologin=false krblogin=false rootless=false applications=WWWBROWSER, MAILCLIENT, OFFICE, TERMINAL, gnome-session-fallback command=gnome-session-fallback rdpoptions= rdpserver= xdmcpserver=localhost

Mac OSX and keyboard
by Paul van der Vlis 02 Sep '14

02 Sep '14

Hello, Is X2goclient working on Mac OSX? I read some messages that there are keyboard problems. Not sure they are gone. Here is such a message, with a link to another message: http://www.mail-archive.com/x2go-user@lists.berlios.de/msg00632.html When the problem is fixed, is this also the case for the Lenny version of X2go? (I have a customer with Macs who does not want to upgrade because the office will be closed in a few months.) With regards, Paul van der Vlis. -- Paul van der Vlis Linux systeembeheer, Groningen http://www.vandervlis.nl

Xwin start failure: unsafe environment error
by Gertjan Hofman 13 Aug '13

13 Aug '13

Hello, I am running 3.99.2.1 on Win-7 64 bit, accessing a Linux desktop locally. Worked fine for a while although I some time got an error which is not persistent: when connecting to the session I get: Xserver aborted due to an unsafe environment. Win was started with the following command line: (null). A quick google of the error brings me to the parsing the args of the x-server. Is the x-server being started with a wrong command line ? Is this an x2go issue or xwin ? If any one can tell me how to collect more info, much appreciated. Thanks Gertjan

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

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
