Shadow functionality in player

[Kiko]

Using the latest NoMachine available, I can’t figure out how to use the session shadowing functionality. Is it available in the player and if so, how do I use it with a shared physical display?

For background, I’m using Enterprise Desktop with the objective of sharing the physical display to a set of Raspberry Pi clients. I am able to connect using regular sessions, but all I need is video streaming; all the input should be done on the server side. I was under the expectation that session shadowing would provide this functionality, but it’s not clear what it is nor how one uses it (with the Nomachine player). Server is Ubuntu 14.04, clients are latest Raspbian.

If I have understand correctly, you want users which are connecting to the physical desktop (sharing it in other words) in view-only mode.

This is on the server side, so the machine which is hosting the Enterprise Desktop software.Open the Server preferences and check the box ‘Require permission to let the remote users interact with the desktop’. That way they will be in view-only mode when connecting from their Player machines to your Enterprise Desktop host.

Thanks, that’s exactly what I was looking for. Is that effectively what Shadow Sessions were, or are those something else completely?

An additional question: does the free version of NoMachine server allow multiple clients to request view-only connections, or does that require Enterprise Desktop?

In version 3.5.0 ‘shadow session’ referred to both sharing the physical desktop of another user, and sharing the X11 desktop. In version 4 it’s the same concept, but you don’t configure the GUI to run a ‘Shadow’ session. Now most of the session configuration happens at runtime based on information provided by the server after authentication to the server has taken place. This includes the type of session (shadowing of the physical screen or creation of a new virtual desktop), the X client or desktop environment (GNOME, KDE, custom session, etc.), the display resolution, the configured printers and so on.

The free version allows one connection to the desktop. So anyone connecting to the computer from another device will count as one connection. To allow others to connect too, you will need Enterprise Desktop.
