desktop sharing: no server


I have Fedora Core 2 and a friend of mine has it too.

My friend setup the desktop sharing in KDE Control Center in a way to allow uninvited connections and to have the remote part to be allowed to take control over keyboard and mouse and setup a password as well.

My friend gave me the IP address of the computer, I could ping it, however, when attempting to get a desktop sharing to my friend's computer, I got message that there was no server available.

I appreciate any help.

Thanks,

Domecq

I don't know about FC, but in debian tcp connections to X are disabled per default (for obvious security reasons).

But that is probably not necessary, depending on what you are trying to archieve. By just taking an ssh connection to the remote machine, setting the DISPLAY variable and running an X application should launch it to the remote desktop, if they are not blocked by xhost setting.

We want to use desktop sharing for KDE training purposes.

Thanks for the tip but I still have no idea on how to allow X remote connection...

Try 'man vncserver' and then see if vncserver is loaded on your FC2 install. I think I had it on my FC1, but can't remember. Then, you can use any number of ways to connect to the process. However, I don't think that there is encrypted transmission, so try to read up somewhere about tunnelling with SSH.

No success with VNC server. My friend enabled it and still I got the same message (no server).

Tunnelling with SSH? This will not allow us to have desktop sharing, will it?

Are you sure vncserver didn't work? There are many ways to do it. Let's say you want to use your friend's desktop from your comp. Have your friend start vncserver, and it'll get listed as a process listening on a certain port. the command has vncserver set on a default port, but i think you can manually specify it. i believe default is 5080, or 5081. again, read man vncserver for it. then from yoru computer, you can a) use vncclient (man vncclient to determine command syntax) or b) use a java-enabled browser and type x.x.x.x:_port in the location bar, where x.x.x.x is your friend's IP, and _port is the port that vncserver is listening on (sorry had to put the underscore in there to make it not show up as a dumb smiley thing. i hate those. don't include the _ when you type it in). try that again and see if it works.

iirc, vnc doesn't encrypt transmissions, so what tunnelling with ssh does is transmits the vnc info via ssh (i.e. encrypted) to you on the other side. ssh doesn't necessarily mean command line. do a google for vnc tunnelling and ssh or some such thing.
