The KDE has a remote desktop connection feature, you might want to try it. It simply uses VNC.
A good vnc client/server is TightVNC. it has some additional compression features upon the standard VNC. It allows you start an unlimited number of screens, which you can connect to.
If you're working in a shell only, you could try 'ssh'. It's a secure encrypted connection (unlike telnet). PuTTY and WinSCP3 are usefull ssh programs for Windows.
If you're working at a Unix/Linux box, and want to see graphical programs at your display, try X11 forwarding.. This is the coolest feature:
ssh -X you@yourmachine
enter your password, and you should get a secure shell. Type any program you'd want, the X11 connection will be forwarded to your local display
You need to specify the "-X" explicitly, because it's a security issue; you allow the remote host to access your local display. Don't turn X11 forwarding on by default in your ssh_config!
Maybe you need to set these settings in
/etc/ssh/sshd_config (NOT: /etc/ssh/ssh_config; that's your ssh-client)
Code:
X11Forwarding yes
X11UseLocalhost yes
...and for a security reasons:
Code:
PermitRootLogin no
Protocol 2
(remove the 1)
You can update sshd_config from your ssh-connection. type "killall -HUP sshd" to restart your sshd listener from ssh
