 ### 4) View only VNC
-Since version `1.2.0` it's possible to prevent unwanted control over VNC. Therefore you can set the environment variable `VNC_VIEW_ONLY=true`. If set the docker startup script will create a random cryptic password for the control connection and use the value of `VNC_PW` for the view only connection over the VNC connection.
