Menu path: Setup > System > Shadowing

For helpdesk purposes, you can observe the client through shadowing. This is possible via the IGEL UMS or another VNC client (e.g. TightVNC).

The user can terminate the VNC connection at any time by clicking on the End shadowing button.
  • Allow Remote Shadowing:

    Makes desktop contents viewable from remote computers via VNC

You can change the following settings:

  • Enable IGEL secure VNC mode:

    Communication will be secured via SSL/TLS and shadowing will only be possible for UMS administrators.

    Further information regarding secure shadowing can be found in the Secure Shadowing How-To.

  • Use password:

    The remote user must enter a password before they can begin shadowing.

  • Prompt user to allow remote session:

    The user is asked for permission before shadowing.

    In a number of countries, unannounced shadowing is prohibited by law. Do not disable this option if you are in one of these countries!
  • Allow input from remote:

    The remote user may make keyboard and mouse entries as if they were the local user.

  • Maintenance screen: Show Image to hide Desktop (Windows):

    An image hides what is happening on the desktop during the VNC session

    • Path to image file: Local file path, for example F:\verzeichnis\bild.png

    You can transfer the required image file to the thin client using the UMS: UMS manual > Files.

    • Drawing mode for the overlay image: Determines how the image is adapted to the screen size:
      - original
      - ignore aspect ratio
      - keep aspect ratio
      - keep aspect ratio by expanding
  • Scale image window (Linux):

    The screen content of the shadowed client is reduced or enlarged by a factor before being transferred.

    Further parameters for the VNC server on the client are accessible in the IGEL registry (Setup > System > Registry > network.vncserver).
