Screen Share: Remote Shadow & Control

VNC: shadow

Developed in-house, shadow allows for simplified VNC Screensharing between Thinlinc sessions, flips and notebooks in the imath network. It is preinstalled on Thinlinc, on imath flips and imath notebooks.

• Start "Shadow Screenshare" from the applications menu, a system tray icon will appear. (Bottom right on Thinlinc, top right on laptops & flips.)

• Left click on the icon and choose either 'View' or 'Share with', a text box will appear where you can enter an ID. Real world examples:

  • Click 'View', enter crose to shadow a colleague with that username. They get a popup asking for permission.

  • Click 'Share', enter 'enured' to share your screen with a colleague with that username. They'll get a popup asking if they want to see your screen. If they accept, it'll again ask you if you actually want to share your screen with them.

  • Click 'Share', enter a room number like k11 or k30 to project your screen to a flip nuc. These are configured to accept shares by default, so you'll get a view request right back.

• A list of all your recent actions is kept, so you don't have to type your colleagues name each time. Simply select an action from the tray icon's menu.

• To disconnect all connected clients, there's a button above the Quit menu in the tray icon's menu.

There is currently no clipboard or scaling support. It's planned for version 2.
