Xcalibur W offers shadowing, enabling the system administrator to take control of any enrolled device using VNC as the underlying protocol. The service is self-managing, allowing one-click usage. Xcalibur W uses HTLM5 for the rendering of the remote session, therefore administrator is required to use an HTLM5 webbrowser.
Xcalibur W features a VNC Proxy that acts as a gateway between the administrator console and the device being managed. As shown below, the VNC session is actually two separate VNC connections:
The port numbers for the outbound VNC connections to the Xcalibur W Server can be customized as below.
Right-click a device in the Device List and select Remote desktop (VNC) from the Contextual Menu.
A task is published to the selected device, requesting it to initiate a reverse VNC session to the Xcalibur W proxy VNC server. The device will pick up the published task and then process it. Once complete, a dialog box - Available VNC sessions - appears, indicating that the device is ready to be shadowed.
From the Available VNC sessions window, the administrator can start a remote assistance session, end a session, or start a view-only session, as shown below.
Click on the VNC connection to open a new browser window (using HTLM5) to shadow the selected device.
Configure VNC-related settings on the Settings page (Views > Manager Options > Settings).
VNC Proxy Automatic Close
