Setting Display Variable when behind Router in Redhat

[lasergecko]

I have a linux (Redhat) machine that I login to using exceed (X server program) on my windows xp machine.
I would like to be able to telnet/ssh out of the linux machine and run X windows apps.
I tried forwarding port 6000 on my router (Linksys) to the linux machine but it didn't work. (I can telnet/ssh out on the linux box but the X windows apps don't work. )
Any suggestions? ( I have a feeling this is easy... )
Thanks

forward ports 6000-6200 through to that machine. Xwindows uses a range of ports, not just 6000. Each new window opened gets a new port, if I remember correctly.

That's true, however, depending on your router setup you may not be able to get that to go. The easiest way to do it for sure would be to use ssh and have ssh tunnel the x sessions. In this case, there's no need to set DISPLAY - just ssh in and fire up an x-app. It should pop up on the x-server.

x tunnels through ssh on my redhat 7.2 installation behind my default setup smc 7004abr router. like khayyam said, just try "xterm" in a ssh window and the display should already be setup.
also, exceed does x-11 forwarding and you can do the same thing with your winxp machine (x windows from a linux/unix box) through the firewall. this took me a while to find.
good luck

Foofoo, how did you get exceed to do the X-11 forwarding?

When I try to use ssh, I get the error message "Disconnecting: Corrupted HMAC on input."
Any ideas on how to fix this?
Thanks.

hi lasergecko,
my bad, sorry to mislead you, i mistyped. it's the f-secure ssh that does the x-11 forwarding that option is in the properties part of the connection dialog box. from there, x will then tunnel to exceed.
hope that this helps.
