HOWTO: Using VNC with linux

1) Make sure you have 'xvncviewer' installed.

2) If you haven't started vncserver previously or it has died for
   example because of a power outage, login to machine "vnc" and run
   the command "vncserver". The command will ask for a password for
   the first time, you can use the same password you use with your
   normal linux account on Metsähovi. When vncserver starts up it
   shows the display number it is using, e.g. "apps1:5", that you
   should write down.

3) Connect to kurp with SSH from your home computer with the command
   "ssh -L 590n:vnc:590n kurp.hut.fi" and replace "n" with the
   display number you wrote down in step 2.

4) Start the command "xvncviewer localhost:n" on your home computer
   (again replace n with display number).

   If you are using an old version of xvncviewer you might get better
   performance by manually selecting the encoding with either
   "xvncviewer -encodings tight localhost:n" or
   "xvncviewer -encodings hextile localhost:n".
