Connecting to a Mariux compute server via VNC

One can connect to one of the our mariux computers and get a GUI without the help of X11.

  • on a mariux compute server (e.g. elvattivo) start a vnc server

    elcattivo> vncserver -geometry 1920x1080 -rfbport 12345 -fg

    In the above command change the port number 12345 to your favorite port number from 1024 to 49151. Ideally one runs this command in a tmux enviornment.

  • To be able to reach this server one has to drill a ssh tunnel:

    local>  ssh -D 12345:elvattivo:12345 geniux.molgen.mpg.de

  • Once the tunnel is established you can connect to the server. On a Mac go to Finder > Go > Connect to Server or press Cmd-K an type

    vnc://localhost:12345

    into the address field.

  • After you are done kill the vncserver by pressing Ctrl-C on the connection to elcattivo in step 1.
