I have this strange problem on SLES9.Things I did:

telnet from a SLES9 (A) machine to SLES9 (B)

su to root
export DISPLAY=A:0.0
When I try to bring up yast2 I get the error
y2controlcenter:cannot connect to X server..

This behavior is observed only on SLES 9 machine..I can bring up yast2 fine using Solaris or other SUSE linux and also RED HAT..

Appreciate any help towards this issue.
Thanks

I know nothing about SLES9, but it sounds like a permissions issue. Try the following;

type "xhost localhost" in a terminal window (without the quotes). This will grants the local
system rights to the X sessions.

Does this work?

If so, edit your .profile file in your home directory and add it. Then you will not have to enter it each time you are prompted.

when logged in to host A, "xhost + localhost" is very similar to doing
"xhost + A" on host A. Note that you must specifically permit any user on
your host to make requests of your user's X server. Otherwise, the default
is to deny all except requests made by X clients initiated by you.

when logged in to host B, and you want the X client on host B to create
a window on host A, then you'll need to permit B to do so with "xhost + B"
on host A.

it's all a consequence of the new X server permission security-mindedness.
