VNC and KDE desktop sharing questions
Can a KDE desktop be shared by multiple clients (for viewing only).
A user group might want to provide a desktop view to remote clients.
I was not able to locate a definitive source where it either allowed or
disallowed multiple VNC connections.

The shared desktop must be running in a virtual X display (not the physical one that is "attached" to the console). You can, of course, open a VNC viewer window from your console's desktop to the virtual desktop. I have done this, but only as a different user between the physical desktop and the virtual desktop. Otherwise the virtual desktop has trouble starting up (it seems that KDE only allows one login instance per user at a time on the same home directory). -Ti

Let me state exactly what the person wants: He wants to be able to broadcast a presentation (and possibly the audio but not the video) from a user group meeting. I think that KDE desktop sharing might be an overkill.

The audio might be a bit tricky, you'll probably need to set up something fancy with network sound. What I've done with this sort of thing in the past was to simply use the speaker phone at the presentation, and let remote viewers dial in on a conference line. Lower tech, but it worked :). -Ti

The audio could be done, but the main issue is the remoting of

I just cannot get this working. I have SuSE Pro 9.1 updated to the latest updates, plus I'm running KDE-3.2. When I try to connect across the Internet to the remote (using the email sent from Internet & Network->Desktop_Sharing on the remote), I receive a message something like "Cannot connect, no server running on remote". Both systems run SuSE 9.1 KDE 3.2. Is there a vnc server within kde's desktop-sharing, or do I need to run vncserver on the remote? Both ends are running a firewall, do I need to specify a particular port to be used, and open it? The KDE setting is to use a random one. I don't want to play around with XFree86.conf as I read some have done. Surely this desktop sharing should run very simply. The KDE help on this subject isn't very helpful and has an empty Q & A section. Anybody got a simple list of things that must be met to get one of these connections across the Internet? Geoff

The following assumes you want to simply run a virtual Xvnc server, not trying to export the native X server (:0) running on your console. I always just start the VNC server manually: user$ vncserver New 'X' desktop is server:4 Starting applications specified in /home/ti/.vnc/xstartup Log file is /home/ti/.vnc/server:4.log You can check that the Xvnc process is running using "ps". You may get a different number than :4. Use whatever it tells you. Then, on the client host, run the vncviewer program to connect to the VNC server: user$ vncviewer server:4 When you are done with the session, shut down VNC server with this command: user$ vncserver -kill :4 The vnc server normally listens on TCP port 5900 + the display number, so if the server is :4, then the port is 5904. If you're running this across a firewall you need to open this up. However this is a security risk, so you might want to look into using ssh tunneling. Look at vncviewer(1) man page for the "-via" command line option.

You shouldn't need to muck with XFree86.conf. -Ti

Yes, of course it can. VNC can be used in classes where all students see the instructor's screen on their own monitors. vncviewer -viewonly

vncviewer -viewonly I think this might be reasonably close to what he wants.
