VNC server can create remote desktop for users on idun-login1 and idun-login2.
Desktop 3 will be used here as example. VNC uses short notation. For example, 3 is mapped to TCP port 5903.
NOTE: Desktop 3 already in use. You'll get another number.
1. Login idun
ssh <username>@idun-login1.hpc.ntnu.no
2. Create VNC password for your account. (Do not use your current password, create unique for VNC)
vncpasswd
3. Start new VNC server. NOTE: you can create only one VNC server.
vncserver
Output:
New 'idun-login1:3 <username>' desktop is idun-login1:3
Starting applications specified in /cluster/home/<username>/.vnc/xstartup
Log file is /cluster/home/<username>/.vnc/idun-login1:3.log
In this example desktop :3 is created. We need to add 5900 + 3. Port 5903 will be used in the next step.
Logout. Use command exit.
exit
4. On Linux/Mac/Windows create SSH tunnel in terminal. Run this command
ssh -L 5903:127.0.0.1:5903 <username>@idun-login1.hpc.ntnu.no
5. Download and run VNC Viewer (Linux and Mac can have pre-installed VNC client)

Type localhost:3 and press Enter
Useful information about VNC
1. List your VNC desktops
vncserver -list
2. Kill your VNC desktop 3
vncserver -kill :3
3. Change picture quality. By default, automatic is too low. Move mouse cursor to the top middle of the remote screen. Change quality to medium.
4. Change screen resolution
