Access to our compute server with software x2go

Besides the access methods ssh and fish there is the possibility to use x2go.

With the x2goclient it is possible to access Linux compute servers of the faculty comfortably from the lecture halls of the university or from home and to transport a complete X session to your own computer.

For this purpose, they use the data sockets available in the lecture halls or their usual Internet access. The method of operation is basically multi-stage:

  1. Connect the computer to the network (also WLAN/WiFi)
  2. Establish a VPN connection with the university
  3. Set up x2go session
Please note point 2, which is essential for accesses from lecture halls and from external. The corresponding software and instructions can be found on the VPN network access Websites of the University Computer Center and on the VPN service of the URZ Website of the MRZ.

Client configuration

After starting the x2goclient the configuration is done via the menu items Session --> New Session.
  • Session name: Freely selectable, e.g.: x2go to case1
  • Host: Hostname, e,g.: case1.mathematik.tu-chemnitz.de
  • Login: Your MRZ username
  • SSH Port: 22
  • Session type: LXDE or XFCE

Troubleshooting - Missing path

  1. Log in once via ssh and write the contents of the PATH variable to a file:
    echo $PATH > dopath.sh
  2. Now edit the resulting dopath.sh. Just add at the beginning
    export PATH=
    export PATH=/usr/bin/TeX:/usr/local/bin:/usr/bin:/bin:/usr/bin/X11:/usr/X11R6/bin:…:/usr/global/bin:/uni/global/bin
  3. After the x2go connection in a console the first thing to do is to call
    source ~/dopath.sh.

Alternative MobaXterm

Download the portable version of Mobaxterm.
  1. start mobaXterm
  2. select sessions, then SSH
  3. enter remotehost and check specify username and enter name
  4. confirm with OK
You get a terminal access (command line) with which you can also start graphical programmes (firefox, matlab...).
