setenv DISPLAY not working

[Guest]

Hi,

I am using kubuntu 8.04 Hardy version and when i try to open any of files from root login (through terminal), i am getting an error message like this:
When I try to open /etc/ssh/ssh_config

No protocol specified
Display :0.0 unavailable, simulating -nw

Can anybody suggest me what could be the problem? and how to resolve.

My second query is, I have a ubuntu 7.10 desktop next to me, to which i would like to have a "xhost" ssh connection from my kubuntu PC. Here also, i am not able to "setenv DISPLAY my_pc_ip_address:0.0 and see the xsession of ubuntu in my machine.

Anybody can give me a solution for the above two in a step by step manner, Thanks a lot in advance, i am totally new to this OS.

Rgds,

in your "normal" user enter: xhost +
in root enter: export DISPLAY=:0.0
then do what you need to do... e.g.: kedit /etc/ssh/ssh_config
though the simple way to do it from "normal" user is: kdesudo kedit /etc/ssh/ssh_config

remote X windows used to be disabled by default in *ubuntu systems.
i believe it still is.
i haven't check lately.
to do what you want to do you have 2 options:
a) use ssh -X ... (basically you connect to the remote system and X is tunneled back)
b) enable remote X windows (i think that's done by commenting out the tcplisten in kdmrc)
then open xhost and set the display variable the usual way...
