Nightly builds for Fedora and EPEL
by Mike Gabriel 21 Feb '14

21 Feb '14

Hi all, thanks to one of our project sponsorers, IMMOBILIEN SCOUT 24, we will be able to provide nightly built RPM packages and RPM release packages directly from upstream in the (near) future. Our RPM packages currently build against various Fedora (18-21 atm) versions [1] and against EPEL (5+6) [2]. The nightly built RPMs still need some work here and there (QA work is still in process), but we are happy to share the test load. For those of you who start playing with our RPM builds: please use our X2Go bug tracking system to report RPM bugs [3]. Please tag your bug report with ''Tag: rpm-packages'', if you think the bug exists in the RPM package itself and not so much in the X2Go code. Don't report to your distro as the distro maintainers cannot help you when playing with package provided by X2Go upstream. We will do our best to support the Fedora packaging team of X2Go to merge our (as we think) improvements into the .spec (i.e. RPM packaging) files.

Remote folder mounting fails sometimes
by Emanuele Marra 20 Feb '14

20 Feb '14

Hi, I configured a shared folder with my x2go Windows client. I noticed that sometimes the mount doesn't work and I get this error in mounts.log: fuse: mountpoint is not empty fuse: if you are sure this is safe, use the 'nonempty' mount option to solve the issue I have to run this commands: fusermount -z -u /tmp/.x2go-USER_NAME/media/disk/_cygdrive_FOLDER sudo rm -R -f /tmp/.x2go-USER_NAME/media/disk/_cygdrive_FOLDER and restart. Any idea why this happens and how to prevent it? Could be a solution to insert the -nonempty option in the mount command, where I can find this in the scripts? I'm a beginner with x2go and I'm not an expert with linux either. Thanks in advance for your help.

x2go Session Broker Configuration
by Dustin Foudray 14 Feb '14

14 Feb '14

Fellow x2go users, I am having issue's configuring & fully understanding the session broker. I am following the instructions at http://wiki.x2go.org/doku.php/doc:installation:x2gobroker#installing_x2go_s… can not figure out how to use it. I have all the service's running but do not understand how to make the broker aware of all of the servers. Is there any other resources that will help with this? -- -Dustin Foudray

Re: [X2Go-User] Trouble with tab key on OS X
by Andreas Yankopolus 13 Feb '14

13 Feb '14

Looks like the tab key cycles focus among open windows of a given application (e.g., multiple terminals). Pressing ctrl-tab gives the correct filename-completion behavior. Everything works fine when I connect from a Windows X2Go client. I've had keyboard mapping issues with the OS X client previously, so my guess would be that the problem is with it. Is there a way that I can fix this key mapping in my install of the OS X X2Go client? —Andreas On Feb 12, 2014, at 11:55, Andreas Yankopolus <andreas(a)yank.to> wrote: > I'm running X2Go Client V. 4.0.1.3 on OS X 10.9.1 and connecting to X2Go Server on Ubuntu 13.10 that reports as: > > x2goagent: 3.5.0.22 > x2goserver: 4.0.1.13 > x2goserver-extensions: 4.0.1.13 > > The problem is that the tab key on my Mac doesn't generate a tab character in the X2Go session.

Trouble with tab key on OS X
by Andreas Yankopolus 12 Feb '14

12 Feb '14

I'm running X2Go Client V. 4.0.1.3 on OS X 10.9.1 and connecting to X2Go Server on Ubuntu 13.10 that reports as: x2goagent: 3.5.0.22 x2goserver: 4.0.1.13 x2goserver-extensions: 4.0.1.13 The problem is that the tab key on my Mac doesn't generate a tab character in the X2Go session. It doesn't perform filename completion in bash or emacs or a tab function in text editors. In bash, the cursor does become hollow when the tab key is pressed. I can get filename completion in bash by hitting esc three times. Needing three presses seems odd—it's usually two. Any suggestions on restoring functionality in tab? —Andreas

Recovering uncooperative sessions
by Dustin Foudray 11 Feb '14

11 Feb '14

Fellow x2go users, I have opened a session, worked in the session some, then suspended it. Today (a day later) I tried to open the session same from a different client but can not get the session to resume. Is there any hope to get this recovered or is it a lost cause? Below is the error I am seeing. NXPROXY - Version 3.5.0 Copyright (C) 2001, 2010 NoMachine. See http://www.nomachine.com/ for more information. Info: Proxy running in client mode with pid '1840'. Session: Starting session at 'Mon Feb 10 13:18:30 2014'. Info: Connecting to remote host 'localhost:31030'. Info: Connection to remote proxy 'localhost:31030' established. Connection timeout, aborting -- -Dustin Foudray

x2go segmentation fault
by Buddy Butterfly 07 Feb '14

07 Feb '14

Hi there, we started to use x2go via ssh proxying. >From there on we experience segmentation faults. In the syslog excerpt below you can see that it starts with the segfault. The last line with the pulse audio is repeated hundreds of times.

Unity Greeter with X2Go Remote Login Support
by Stefan Heitmüller 06 Feb '14

06 Feb '14

Hello everyone... After testing and beta-deploying X2Go services for some test users (developers/qa/it - who really liked it), i was trying to implement the x2go-broker into lightdm. I followed the steps in http://blog.x2go.org/index.php/2013/04/28/289/. First of all, "get-build-deps debian/control" seems to be replaced by "mk-build-deps debian/control" ... After compiling, installing and configuring i see the additional login in lightdm. Our Active Directory enabled (using likewise-open -> pam) broker delivers https://x2go-broker.our.domain.com/uccs/inifile/api/4 , asks for user/password and prints the json-object containing all configured servers. When lightdm starts, i can see some traffic between the machine and the broker. Logging in seems not to work, i've tested "test.account@intern", "test.account(a)our.domain.com" and even a local test user (on the broker, right?) There is no communication between the broker and lightdm/unity-greeter when trying to login. How can i help you further? (debugging,..) As this is a relly nice and seemless solution for our clients, i think we cann afford some sponsoring there too. regards Stefan

sshfs through broker
by Stefan Heitmüller 04 Feb '14

04 Feb '14

I'm just trying to adjust the x2go-setup to our needs... When i'm directly connected to one of my x2go-servers, the sshfs-tunnel works perfect. Pasting the config lines to the broker config file, i see a sshfs process running (server side), the server appears in /var/log/auth.log (client side), no error in mounts.log but no mounted folder appears.
