IGEL OS offers the ability to observe the endpoint device via shadowing through the IGEL Virtual Network Computing (VNC) Viewer in the Universal Management Suite (UMS) or another VNC client (e.g. TightVNC), see Universal Management Suite > UMS Reference Manual > Devices - Managing Devices in the IGEL UMS > Shadowing - Observe IGEL OS Desktop via VNC. The shadowing of IGEL OS 12 devices through the UMS is always via Unified Protocol, i.e. communication is always encrypted. This article shows the settings for configuring the VNC access to your devices.

Menu path: System > Remote Access > Shadow

 

 

Allow remote shadowing

☑ Desktop content can be accessed by remote computers with VNC software.

☐ VNC shadowing is not allowed. (Default)

If Allow remote shadowing is activated, you can change the following settings:

Deny shadowing via external VNC tool

☑ The device can only be shadowed via the UMS. Shadowing of the device by an external VNC viewer is not possible. For details, see Universal Management Suite > UMS Reference Manual > Devices - Managing Devices in the IGEL UMS > Shadowing - Observe IGEL OS Desktop via VNC > External VNC Viewer. (Default)

☐ The device can be shadowed by an external VNC viewer, not only the UMS.

 

Use password

☐ The remote user is not authenticated for shadowing. (Default)

Password

Prompt user to allow remote session

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

 

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 Disconnect button with which the user can terminate the VNC 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 device is reduced or enlarged by the Scale factor before being transferred.

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

 

Scale factor

Factor by which the screen content of the shadowed device is enlarged or reduced. Values under 1 reduce the content. (Default: 1.0)
