Ok so I have a Fedora 3 server running now and I want to be able to not connect a monitor/keyboard/mouse to it and just put it in another room and leave it. But I want to be able to administer is remotely. I was doing this with a Windows box using Remotely Anywhere. I was reading about Webmin but it doesn't seem to be able to actually CONTROL the linux box, just edit settings and such.
Like with remotely anywhere you could bring up the actual windows desktop in internet explorer and control the mouse, type, etc just like you could if you were actually sitting in front of the computer
Anything that is able to do this on Linux?

Yes you can do exactly that. Search the board for posts containing "VNC" within the last 1 day and you will find a howto I wrote on configuring VNC for X.

Want to learn more about VNC and what it is?
