One of the many joys of using Linux and computing in general is being able to control another computer over a network. Remote desktop functionality existed in Windows 98 SE and exists now in XP Pro. But I've never seen anything as completely transparent as being able to run a piece of software on another computer in my LAN with the GUI showing up on my local unit like you can in Linux. I used to use kdessh (I think that is the command) to start up kppp on another machine that had my modem connection to the internet and get the graphical interface on the other computer I was sitting at. I could then use that little traffic monitor to see how my connection was going.
But the ultimate would be to get an entire desktop for that other machine on the computer I was sitting at. I think this is the basic mission of the X Windows system and its open source implementation in XFree86. I have yet to get even a clue as to where to start or even if it is possible as I imagine.
Now in Red Hat 8.0 there is a tab in the GUI Login manager; -> Systems Settings -> Login Screen; that is for XDMCP. I've done some searching and found a HOWTO on it here: http://www.tldp.org/HOWTO/XDMCP-HOWTO/.
It sounds like some way of getting your login window to provide with prompts to log in to another computer on a network using a complete desktop. But even with the few HOWTOs I've read and applied, I have yet to see a prompt to do this on my own system.
Has anyone ever successfully managed to create a login window for remote systems using the XDMCP technology? Is it actually possible? How do you do it?
Any and all tips and clues would be appreciated.
