Re: [PLUG] Remote KDE Session

Hash: SHA1


Working strictly from memory(1)...
Both Chris Grabowy and Jeff Bailey are right-on...

Beware: X uses a weird method of defining "server" and "client".  It's been a
bone of contention for the X critics for about 2 decades.

IF you are already running a window manager on your workstation (you most
certainly are) then

1. Make sure that your local display is accepting external connections:
Open a terminal on your workstation and enter:
xhost +

2. Forward X to your existing computer's display through ssh:
- From the same terminal window type:
ssh -X  me@my_server

3. From the forwarded ssh session:
xterm &

THAT should get you an xterm on your server but displayed on your workstation!
If that works then from there, I just create shortcuts on my desktop that start
the desired program on the remote system

For example,  ssh -X eric@neptune firefox
Will open an instance of firefox on my workstation BUT it will be running on my
laptop (neptune.)

Now, if you want the entire desktop then you're back to NX or vnc or similar.
That's not necessary though.

Hope this helps.


1.  Ask about my "comet" theory of memory some time over beers.  I promise I'll
keep it short... because I don't remember much of it.
