Nymph Station

Nymfe * stations are student stations in the PC hall and in Linux classrooms (B130, A219). During the semester, the stations are open on weekdays from 7 am to 8 pm. If someone is logged in at 8 pm, the machine will not shut down until 10 pm. Nymfe01 and Nymfe02 are an exception and run nonstop (except reboot at 5 o'clock). Due to restricted access to the FI network can be connected to Nymfe * machines remotely only from the MU network (for example via the machine Aisa ).

In addition to the usual remote access via SSH, you can also use, if necessary remote access via VNC .

From Nymph * you can also access the Windows home directory .

They display the current station occupancy room maps in the Faculty Administration.

You can also read about the older atypical problem , which we addressed in connection with the Nymphs.

Graphical interface control from another machine

Help x2x you can control another Nymph machine from your laptop (or some Nymph machine) (this can be a useful alternative to free-standing monitors):

  • log in to the graphics session on Nymph, which will serve as a "secondary display"
  • find out the name of the display via echo $DISPLAY - It is most often :0 , which we will further assume
  • from another machine, which will serve as the primary and which keyboard and mouse will control the second machine, log in to Nymph:

    notebook$ ssh -Y xlogin@nymfeNN
    xlogin@nymfeNN$ x2x -to :0 -east
    
  • if everything goes well, the command seems to get stuck; if you then move the mouse to the "eastern" edge of the laptop screen, the cursor should move to the secondary screen and you should be able to control the windows with the mouse and keyboard of the laptop

Other placements may be selected according to the world, but this may not always work. Especially if you have a Unity interface on your laptop (the default for Ubuntu), -west and the most natural -north cannot be used due to the presence of Gnome Shell toolbars. You may need to use XMonad or if you have problems with maximized windows -struts . Copying can also be a problem - then try using the middle mouse button. (No, you probably can't chain several Nymphs in a row.)
