Friends.

I want to teach linux to my remte friends.
We may be in a same network or may be in internet.

I need this kind of setup.

They all can connect to my linux and get a window open in their machine.
I can show anything on that window to all.
I may show the impress presentations, my shells, my configurations files, my settings etc.
I have to guide them by showing them and i have to talk them in voice, so that they can have a very very live session in the internet.

How to do it?

Please suggest. We can create virtual classrooms if we can.

Thanks,
T.Shrinivasan.

There are 2 remote desktop systems around currently, NX and VNC.

They are both fairly similar, NX is faster than VNC but has a bit more of a setup requirement, mainly because it was only recently GPLed and having slightly different systems can cause problems, the client has problems if the server is a different version and the server was a PITA to get working on x64 last time I tried (A while ago now though). VNC is simpler but slower, I know it also supports listening connections without interaction which might help for teaching (not sure if it supports multiple connections but there are various server implementations so some might and some might not).

Both NX and VNC have several variants (RealVNC, TightVNC, 2X, no-machine NX and more)

For the voice I would just go with Skype or some other VoiP system Ekigua

It might also be worth setting up a file server that they can access, such as under samba or ftp or just http indexing.

Thanks Hegemon.

I dont want my friends to login into my system via VNC.

If it has listening mode, it would be nice.
let me check it.

Regarding voice, i dont want any third part service like skype or wengo.
Ekiga would be nice.

post you after i setup everything.
