x2go client timeout when x2goagent cannot resolve ip
by Nikolaos Kefalas 21 Jul '14

21 Jul '14

I have an Ubuntu 14.04 x64 system with x2go PPA, where certain users are restricted from accessing the Internet, but only local network and loopack access is allowed. When i try to login from a x2go-client from another system, the client connects to the x2goserver but after while it timeouts. I suspect that the x2goagent which runs with user uid tries to resolve the incoming ip and stalls there waiting the reverse dns lookup to be completed. Is any way to disable ip address reverse dns lookup for x2goagent? Best regards, Nikolaos Kefalas

Added wiki page doc:de-compat "Desktop Environment Compatibility"
by Michael DePaulo 16 Jul '14

16 Jul '14

http://wiki.x2go.org/doku.php/doc:de-compat Contributions are welcome. More info per distro and release of distro is needed. For example, which exact packages to install for GNOME3. Also, references/links should be inserted throughout the wiki. I've added a few. Also, I tried to add a link to it on the "X2Go Documentation" box on the home page, but when I did so, the Documentation box became taller than the "Get Support" box, which in turn looks like crap. When I tried to add a single newline to the "Get Support" box according to the documentation here: https://www.dokuwiki.org/wiki:syntax#basic_text_formatting I instead added 2 new lines, so the "Get Support" box became taller than the "X2Go Documentation" box. -Mike#2

nice article - Using WikID with x2go for 2 factor authentication
by brian mullan 15 Jul '14

15 Jul '14

This just popped up on HowToForge as a new article post so I wanted to make others aware of it: Securing X2Go On Ubuntu Precise With WiKID Two-Factor Authentication In this document we are going to demonstrate how to implement two-factor authentication from WiKID <http://www.wikidsystems.com/> for remote desktop on an Ubuntu 12.04 server using X2Go. The WiKID Strong Authentication System is a commercial/open source two-factor authentication solution. X2Go <http://wiki.x2go.org/doku.php/doc:newtox2go> is an NX-based remote desktop tool. First, we will configure a domain on the WiKID server, then add the targeted server as a network client to the WiKID server, and finally configure the Ubuntu Precise box for x2go using pam-radius. Note that if you already have a server configured as an SSH gateway box with pam-radius, you can simply add X2Go to and it will work.

No button icons on Ubuntu 14.04
by Ulink 10 Jul '14

10 Jul '14

Hi, updated a x2go server from xubuntu 13.10 to xubuntu 14.04 (64 bit) lately. Now if I start a application (e.g. gedit) via x2go "application" session there are no button icons shown. If I start a desktop session and the same application within this desktop session the button icons ARE shown. Any hints? -- Bernhard

Suspending terminates applications
by Wolfe, Kevin [USA] 08 Jul '14

08 Jul '14

Hi, I have set up x2goserver on an ArchLinux machine and am connecting in through a Windows client. The server is a headless, no-desktop setup and am connecting in for shell purposes only. I run 'xterm' as a custom program upon connection, which starts fine. However, when I attempt to suspend the connection (using the GUI pause button, or closing the client program, no difference), the session terminates - killing all applications run through the xterm window. Further (and I may not know exactly if I'm checking this right), I do not believe that the session is registering in the database (as viewed through sqliteman). Any assistance in debugging would be most appreciated. - Kevin

Use /etc/hostname if you don't have a proper DNS setup in your lab.
