Mike on Debconf video

Hi, You need a really new browser for this video (Iceweasel/Firefox 17 does not work, Chromium 28 does work). http://www.irill.org/videos/debconf13/X2Go_Terminal_Server_Suite_and_Debian… In my opinion it's a very good idea to use a driver in Xorg to avoid the license problems. With regards, Paul van der Vlis -- Paul van der Vlis Linux systeembeheer, Groningen http://www.vandervlis.nl

X2goclient: Bringing up NX3 proxy failed.
by Nigra Truo 16 Aug '13

16 Aug '13

Hi, my x2goclient stopped working a day ago and I cannot get it to connect to my x2goserver. X2goclient on Windows works, so it must be a Linux client problem. I removed and reinstalled the client, tried it as another user, purged config, all to no avail. When using x2goclient, X2Go client V. 4.0.1.0 (Qt - 4.8.2) on server: 4.0.1.6-0~x2go1+wheezy~main~712~build1 I get this message: Can't load translator (:/x2goclient_en_us) ! Can't load translator :/qt_en_US Connection timeout, abortingInfo: Aborting the procedure due to signal '15'. Session: Session terminated at 'Thu Aug 15 17:13:47 2013'. and a question box if I want to terminate the session. when using pyhoca-gui --libdebug I get this output: (failed to start NX3 proxy, but no reason why) -------- Xlib.protocol.request.QueryExtension pyhoca-gui[31820] (x2goinifiles-pylib) INFO: proposed config files are ['/home/browny/.x2goclient/sessions'] pyhoca-gui[31820]

x2golxdebindings for squeeze relies on 'update-icon-caches' being available in it's postinst script
by Holger Krause 15 Aug '13

Dear all, I just wanted to update x2golxdebindings from version 1.0.1.3-0~x2go1+squeeze~main~30~build1 to 1.0.2.1-0~x2go1+squeeze~main~41~build1 on a squeeze system.

Thanks for providing x2go! Holger

Missing Dependencies while installing on RHEL5
by Kermit Short 14 Aug '13

14 Aug '13

Greetings, I'm trying to install on 32 & 64 bit RHEL5. I've downloaded the RHEL5 repository file but when I try to install x2goserver, I get a dependency conflict on perl(Sys::Syslog). Apparently I do have a version of the perl module installed that's insufficient. When I try to install an upgraded version, I get a package conflict with Perl itself. Has anyone seen this? More importantly, has anyone found a work around? Thanks! -Kermit Short

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

Mac OS X client and ssh-agent?
by Tom Harris 08 Aug '13

08 Aug '13

Are others seeing the behavior I am? I have an open x2go session running and leave my computer for a while. When I return, the session has timed out and I get the dialog asking if I want to close it. But, when I close it and try to re-open a new session, it fails to connect. Only after I go to a terminal shell and kill the ssh-agent process does it re-connect. I am using password authentication, and it works fine after stopping ssh-agent. Is there some setting I have wrong?

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