Broadcast teacher's desktop

[Pau Cabot]

Hi everybody,

I'm a teacher in a Majorcan school and I would like to use vnc as a 
"teacher desktop viewer": the pupils should be able to watch in their 
own screen the actions the teacher do in his/her desktop. Do you know 
the way to do it?

I have read a lot but i have not been able to find a solution for my 
problem.

Things I have tried:
- krfb+krdc (only allows one client)
- vncserver+vncclient (dispays me a different X session)
- x11vnc: http://www.karlrunge.com/x11vnc/ (it works in Debian, but not 
in SuSE)
- xf4vnc: http://xf4vnc.sourceforge.net (I cannot boot X with the new 
XF86Config generated by the program)

Things I have NOT tried:
- XMX: http://www.cs.brown.edu/software/xmx
- NX: http://www.mirrors.net.ar/pub/suse/i386/supplementary/X/NX/
- This: http://www.realvnc.com/v4/x0.html

What do you recommend me? Which would be the easiest way to solve it?

I am using SuSE Linux 9.1 on both teacher and pupil's machine.

Thanks in advance,
