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

For Remote Working, Use Secure Shadowing

If the endpoint device is in a mobile or work-from-home environment, it is highly recommended to use secure shadowing only. Regular shadowing without encryption poses a security risk.

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

    ☑ Desktop content can be viewed from remote computers with VNC software.

    ☐ VNC shadowing is not allowed. (default)

You can change the following settings:

  • Secure mode

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

    ☐ Communication will not be secured via SSL/TLS. (default)

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

  • Use password

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

    ☐ The remote user does not require a password for shadowing. (default)

  • Password: Password for the VNC connection
  • Prompt user to allow remote session

    ☑ The local user will be asked for permission before shadowing. (default)

    ☐ The local user will not be asked for permission.

    In a number of countries, for example Germany, unannounced shadowing is prohibited by law. Do not disable this option if you are in one of these countries!
  • Allow user to disconnect remote shadowing

    ☑ A button with which the user can terminate the connection is shown. (default)

  • Allow input from remote

    ☑ The remote user can make entries using the keyboard and mouse as if they were the local user. (default)

  • Scale frame buffer

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


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


    ☐ The screen content is transferred in the original size. (default)

  • Scale factor: Factor by which the screen content of the shadowed client is enlarged or reduced (default: 1.0)
