VNC means Virtual Network Computing and RealVNC is a freeware remote control app, similar to pcAnywhere.
With versions for MS Windows and Linux, this great little tool lets you take over another machine's desktop, just as if you were connected to it through keyboard, mouse and monitor. Essential equipment in any NetAdmin's toolkit, I reckon.
Fedora Core 5 usually has the server part installed already, leaving the client part to be installed manually.
Do it on a system with an internet connection and it'll download the latest version and also any dependencies, automatically.
To install the remote control client, from the KDE start menu go to System | Add/Remove Software. Under Package Manager, click the Search button, type in the word vnc and click search.
In the resulting box, note that the VNC Server should already be ticked, so tick the vnc-4.1.1-36.fc5.i386 option (or current version name), which is the client. The system should grab all the files it needs from the 'net.
You can control MS Windows from Linux and Linux from Windows, although the latter is a bit crap and I'd sooner use SSH.
To see this server part in all its mediocrity, open a command shell/terminal from within KDE and type:
..providing a password when prompted. Connect from another system using the VNC Viewer application (downloadable from http://www.realvnc.com).
In contrast to running the VNC Server, the client does a damn fine job indeed. It's dead cool seeing Windows XP sitting on the KDE desktop, being run from Linux. Make sure the VNC Server service is running on the target system. To run the viewer from linux, open a command shell/terminal from within KDE and type:
where hostname refers to the name (or IP Address) of the computer to be controlled. VNC can even be run as a service, allowing remote control at any time.
