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

Re: [X2go-User] Mac client 'Can't connect to X-Server
by Neil Hunt 14 Nov '12

14 Nov '12

Paul, Unfortunately as a regular user of the Mac X2go client, this is something I've seen many times. Unfortunately, I haven't found any fix for it. The good news is that it rarely happens if you keep the X11 application open. Always open X11 before starting your X2go session. From there, you can stop/start X2go sessions, even the X2go client itself, however I almost always keep my X11 app running even when it's not being uses and then I don't get the problem you are describing. If I quit X11, especially if it's accidental during an active X2go session, then I end up with the problem you are describing and the only option is to restart the whole computer. But if I keep it open, I go for days or weeks without rebooting. Ultimately, I think we should look to move to the PyHoca gui, but we haven't been able to find any serious python developers to port it to OS X.

Many people at my work use x2go's Mac client. We have never been able to figure out how to resolve the 'Can't connect to X-Server' error without random acts (eg. rebooting). We are not sure why it comes up. This is what I do: 1. Start X11.app 2. ssh -X remotehost 3. xterm & So far this works, I get an xterm so there is nothing wrong with X11 4. Start X2Go client 5. Start a session (port 22, dsa authentication, Gnome...) 6. Client gives the error and hangs (Abort and Terminate don't do anything) and I have to close the application. The closest we got to figuring it out is that the X11.app possibly changes it's DISPLAY on restarts and perhaps the x2go client is expecting display 0. Is there any more debugging information that I could get from the client to see what exactly it is doing prior to giving the error message? We have tried some of the suggestions in the forums, such as changing permissions in X11.app (this is necessary), starting it manually before starting the client. We have also done things like messed with firewall settings, made sure hostname doesn't change on our laptops between work and home, deleted preference files, delete XAuthority files, etc. What seems to work is rebooting. Thanks, P?l

xming 6.9.0.31 keeps crashing
by nigra truo 21 Sep '12

21 Sep '12

Hi, I use x2go a lot on Windows, but have noticed that the xming server keeps crashing from time to time, usually when I seem to have firefox open in the session with lots of tabs. It takes me usually some effort to close the tabs, as it keeps crashing and crashing. Is there a workaround for this? This is with X2go client 3.01-2 on Windows. I know this is an old version of X2go, but when trying the new version, they both fail on Linux and Windows with the error "cannot open X screen" or something. (do I have to upgrade the x2go server too, might that be the problem to be able to use the new client? I depend on x2go and use it long hours every day so breakage is annoying) Thanks, Markus

Is your /etc/ssh/sshd_config set up to allow X? You may wish to try the following settings: X11Forwarding yes X11DisplayOffset 10 X11UseLocalhost no Good luck - John

Shared folders only work when connecting locally
by Angel Tsankov 22 Jul '12

22 Jul '12

Hello. It seems that shared folders only work when server host is the same as client host. If I start a new session on a remote host I do not get the ~/media symlink there. Any ideas why this happens or which log files I should look at? Regards, Angel Tsankov
