recommended app to remote connection
 

I want to connect from openSUSE 10.3 to other computers with systems Windows and Ubuntu to help its owners with problematic tasks.

When I had Ubuntu I tried VNC without success. I did not manage to connect to another machine through external IP.

I like to know which alternatives exist in Linux for remote connection (with GUI), to be operating in the main distros: openSUSE, Ubuntu, Debian, ...

You can use ssh to do remote login. ssh with the "-X" option will let you run graphical programs remotely. Something like:Where "user" is the user name and 192.168.0.1 is the IP address of the remote computer. Read "man ssh", it has a lot more information. I believe you can install ssh on Windows as well.

Thanks, I didn't know SSH, but is a less well-known protocol among the basic users of Windows, VNC is more standard.

I get it now with VNC. I connected with a Windows computer inside the internal network, but not get it if I write the IP external.

I activated the Remote Desktop and opened the VNC port in firewall for the correct authenticated.

This can occur for having the same one IP external in the router to connect us to the same network?

Besides, there is some graphic application launcher for vncviewer?

solved
 

I found the problem!

One must open the port (5900, default vnc port) in the router to be able to redirect to the internal IP.
