x2go client side printing
by Steve Bergman 29 Jun '14

29 Jun '14

Hi, I'm running the latest x2go server on Debian 7 Wheezy. I've got the x2go-printing package installed, as well as the cups-x2go package. Browsing is enabled in cupsd.conf. 'Client side printing support' is enabled in the client. And I've restarted the cups server, and logged out and back in after installing the print packages. But my printer is not appearing in MATE's list of printers. Is there something more I need to do? This is operating over a vpn, so there is no firewall involved. And sound works fine. Thanks for any assistance. Steve Bergman Oklahoma City, OK. USA

pulseaudio
by Frédéric Henry-Couannier 29 Jun '14

29 Jun '14

Dear I'm trying for the first time x2go between an RPI (thinclient) and a Mageia PC (server) and for the time being i get a horrible sound (almost impossible to understand a speach) when i read a youtube video. I have KDE on my Mageia PC and i'v readen in various web pages that there is a problem running pulseaudio on KDE, however i see many packages available for pulseaudio, many of them already installed so may be KDE-pulseaudio compatibility is an old problem which is now solved (?) So i have no idea eventually what config should i use (pulseaudio?, arts?, eds?) and what packages should be installed on the source and sink sides (pulseaudio is there and all right on both sides as far as i could check) I also guess that a firewall configuration is needed not to block the pulseaudio default port...(?) Thank you in advance for any helpful suggestion or reference to read. regards, Fred

The information on the X2Go web site and in the flyer I got at the CLT 2014 (which actually motivated me to try x2go) is in respect to the generation of the keys (at least for me as a first time user of x2go) not sufficient. To solve the problem I threw out all generated keys (user on server, user on remote client) and followed the description in Michael W. Lucas: SSH Mistery (ISBN 9781470069711) Now I have the various types of keys on both machines. And with the correct settings in the session profile everything works, even automatically. Thanks for your hints. KDJ.

Important information: Wrong version of X2Go Server in Baikal LTS Debian archive
by Mike Gabriel 19 Jun '14

19 Jun '14

Dear all, == Summary == we got informed by John McMonagle [1] about wrong package versions in the Debian archive of X2Go. Unfortunately, I only grasped the severity of that bug report a couple of days back. In February 2014, a development snapshot of x2goserver* packages found their way into the Debian-based package archive of X2Go Baikal LTS [2]. This is of course a severe issue and after cross-checking last Monday, I reverted those uploads and provided the correct package versions (X2Go Server 4.0.0.11). No other area of the package archive was affected, only the Baikal LTS packages of X2Go Server for Debian. == How to downgrade == Follow these steps for downgrading the development snapshot (4.1.0.0-preview) to the current Baikal LTS release of X2Go Server (4.0.0.11). Open a terminal and run these commands... $ apt-get update $ apt-cache show x2goserver ### you should see two version of package x2goserver ### x2goserver 4.1.0.0-0x2go1~<something> (which is the currently installed version) ### and ### x2goserver 4.0.0.11-0x2go1+git20140615.736+<debversion>.baikal.1 $ cp /etc/x2go/x2goserver.conf /etc/x2go/x2goserver.conf.bak $ apt-get remove --purge x2goserver-common libx2go-server-perl libx2go-log-perl $ apt-get install x2goserver x2goserver-xsession x2goserver-printing x2goserver-fmbindings $ cp /etc/x2go/x2goserver.conf.bak /etc/x2go/x2goserver.conf ### You may want to view changes between the two config files... $ diff -ur /etc/x2go/x2goserver.conf.bak /etc/x2go/x2goserver.conf # and manually edit the one now installed as x2goserver.conf I am very sorry that this happened, it should not have!!! If you need further help, please contact either me or any other of the devs via our mailing list x2go-user [3] or via IRC [4]. light+love, Mike Gabriel [1] http://bugs.x2go.org/cgi-bin/bugreport.cgi?bug=429 [2] deb http://packages.x2go.org/debian {squeeze,wheezy,jessie,sid} baikal [3] http://lists.x2go.org/listinfo/x2go-user [4] #x2go at irc.freenode.net (my nick there is "sunweaver") -- DAS-NETZWERKTEAM mike gabriel, herweg 7, 24357 fleckeby fon: +49 (1520) 1976 148 GnuPG Key ID 0x25771B31 mail: mike.gabriel(a)das-netzwerkteam.de, http://das-netzwerkteam.de freeBusy: https://mail.das-netzwerkteam.de/freebusy/m.gabriel%40das-netzwerkteam.de.x…

by Mike Gabriel 19 Jun '14

19 Jun '14

Hi all, unfortunately, our second server machine required some emergency maintenance yesterday, so that we had to take several services offline yesterday: o package archive o mailing lists o Git repository o bug tracker The system went online yesterday around 15.00 UTC after being down for about 4-5hrs. We apologize for the inconvenience, Mike Gabriel (on behalf of the X2Go team) -- DAS-NETZWERKTEAM mike gabriel, herweg 7, 24357 fleckeby fon: +49 (1520) 1976 148 GnuPG Key ID 0x25771B31 mail: mike.gabriel(a)das-netzwerkteam.de, http://das-netzwerkteam.de freeBusy: https://mail.das-netzwerkteam.de/freebusy/m.gabriel%40das-netzwerkteam.de.x…

Connection time out, possibly because of ssh tunnel creation failure
by Jakub Urban 16 Jun '14

16 Jun '14

Hello, I cannot connect any more to an x2go server which used to work before. The only thing I can think of that's chaned is the kernel version. The server is a Scientific Linux 6.5 with kernel 3.10.36-1.el6.elrepo.x86_64. x2go is installed from EPEL (x2goserver-4.0.1.13-4.el6.x86_64). Below are logs from the server and pyhoca-gui (although the connection does not work from x2go clients on Windows/Linux either). Anybody has any idea why this does not work? There is no firewall in between the machines.

Dev packages for X2Go Server "sneaked" themselves into the Baikal LTS package archive
by Mike Gabriel 15 Jun '14

15 Jun '14

Control: close -1 Hi all, I have just stumbled over a very severe flaw in our X2Go package archive for Debian [1]. A development snapshot of X2Go Server (4.1.0.0-preview) got uploaded to the Baikal LTS area. That is a very very severe problem to people who run the long-term supported version of X2Go Server. I have just kicked of a rebuild of all X2Go Server packages of that archive and will provide an announcement and a troubleshooting / downgrading recipe tomorrow. I deeply apologize for this very severe flaw and big thanks to John McMonagle for unravelling this. Unfortunately, his message got ignored till now...

Occassionally very slow display update
by Milan Knížek 12 Jun '14

12 Jun '14

Hello, I run x2go server 4.0.1.15 on Arch Linux x86_64 xorg-server 1.15.1 x2go-agent 3.5.0.24-1 nxagent 3.5.0.24-1 and x2goclient V.4.0.2.0 (Qt - 4.8.5) on Windows 7 with internal X server. (Installed without admin privileges and running in portable mode.) Anyway, the issue described below happens for many months now, thus it is not related to those particular versions. After connection to the server, the desktop session (KDE) works just fine. However, once I start using apps (usually Firefox, Evolution, Smartgit, digiKam, Dolphin, etc.), the screen behaves like there are timeouts or short drops in connection. The screen may freeze for several seconds completely, it does not react on clicks, keyboard typing, though it still remembers the actions and "replays" them once the desktop resurrects: e.g. the clock widget on task bar quikly displays the seconds timer changes, like in an accelerated movie, then it freezes again. Other times, it just becomes horribly slow - slowly redrawing. A temporary solution is to close the app window and start it again. It usually helps better to disconnect (logout) and connect again. Suspending and resuming the session from the client does not help at all. Note that these issues are not caused by a bad connection per se: I can open another SSH connection from cygqin and transfer big files back and forth w/o problems at full speed (cca 2 Mbps up/down). SSH typing response is also quick, hence latency should not be an issue either. Logs on the server (syslog, x2go log level debug, CLI output of the applications) do not show anything interesting at all. I assume it may be due to the often discussed issues with applications being compiled against up-to-date X libs, while nxagent still uses the old X server. I have tried to use x2goclient on Ubuntu 12.04 (armhf) for some time and it seems it runs stable, w/o the issues. Is there anything I can do at all to improve the user experience? Or at least to debug the issues? regards, Milan -- http://milan-knizek.net/ About linux and photography (Czech only) O linuxu a fotografování

Solution X2GO Session Broker and X2Go Server over Docker.io
by Felix Hosner 12 Jun '14

Hi All In my lab, I would like to build a solution with X2Go Session Broker and X2Go Server with Docker. In the documentation of Session Broker is described as the X2Go server must be entered in the "session profile configuration". host=s-1.pool-e.local (10.0.2.11),s-2.pool-e.local (10.0.2.12),s-3.pool-e.local (10.0.2.13),s-4.pool-e.local (10.0.2.14),s-5.pool-e.local (10.0.2.15) But Docker works over a port mapping. An entry would therefore have to look like this: host=server1.local:xxx1 (10.0.2.11:xxx1),server1.local:xxx2 (10.0.2.11:xxx2),server1.local:xxx3 (10.0.2.11:xxx3),server1.local:xxx4 (10.0.2.11:xxx4) Is that a problem? (Yes / No) If Yes, how can the Probelme be solved and how the solution could look like? Thank you for your feedback Felix PS: Docker - http://www.docker.com/ -- *Notabene: * Die Zukunft soll man nicht voraussehen wollen, sondern möglich machen. Antoine de Saint Exupéry (1900-44), frz.
