IIRC, there are various ways to "forward" an X display from one machine to another (that is, to run an X application on one machine but view and control it on another machine) -- starting to collect some notes and resources.




Using ssh

yeah, and if you are ssh'd in,, start it like this:

ssh -C -X hostname.domain

from your linux box..

then you can start mozilla and check it in a pretty gui smile (the X in that ssh command means to forward X, so when you start mozilla, its display is forwarded to your ssh client..) very handy, you can run mandrakeupdate and stuff like that as well...

  • -C is compression — helps on a slow connection / modem, can hurt on a fast network — see man ssh
  • -X is X forwarding, but you often don't need to specify this if other things are set up appropriately on your system — see man ssh

Notes from Others

to be digested

from Dr. Andrew C. Aitchison on xfree86@XFree86PLEASENOSPAM.Org ca. 9 Apr 2003:

This is for a gfx cluster and there is no use in logging into every node.. So that i can ssh to a node, set the display to itself and run my cluster app.

I would disable xdm/kdm/gdm.
When I ssh in I would start the X server, and then run the cluster app.

Red Hat (and possibly other distribrutions) does some console locking (in /var/lock/console* amongst other places) to stop remote users from doing things like playing music through your speakers and reading your floppy disks. This can interfere with starting X when logged in remotely.
