After starting sshd on Opensuse 12.2 x64
On the putty I get error message:
Xforwarding refused.
sshd config seems ok.
Any idea?
On the server side, it should work out of the box. On the client side, you need to use ssh -X or ssh -Y.

Did you configure Putty to forward X? It doesn’t by default, but it’s a
checkbox that when enabled seems to work pretty well. Also, I presume
Putty is on windows; if that’s the case, do you have an X server on the
windows side as well? xming is an example of a free/easy one to get
going if you do not already have one. Also, did this work in the past?
Does it work with other machines?
Good luck.

Did you configure Putty to forward X?
Only the new OpenSuse 12.2 install not working. Other systems yes.
With the ssh -X host command I have the same situation. The DISPLAY environment variable not setting.
On firewall port 22 open.
In /etc/ssh/sshd_config file
Port 22 uncommented
X11Forwarding yes (originaly uncommented)
You only need to uncomment “Port 22” in /etc/ssh/sshd_config if you run sshd on other ports (too).
DISPLAY has to be set to the IP:<display>.screen] of the ssh client.
example:
export DISPLAY=192.168.1.4:0.0
I want to use via the SSH tunel, so this DISPLAY setting doesn’t working automatically. (NAT, etc.)
I installed CEntOS its working properly. I installed again OpenSuSe and have the same problem.
On remote:**
ssh -X host**
On OpenSuse**
xterm**
xterm: Xt error: Can’t open display:
xterm: DISPLAY is not set
PLEASE HELP !!!

What are you doing that is non-standard during installation? I just
built a new OpenSUSE 12.2 x86_64 host and while it is not running a GUI
it does have the X libraries installed (running at runlevel 3). I just
SSH’d in with -X (from the command line, not using Putty) and am able to
get ‘xeyes’ running properly by calling it normally (a simple test of X
functionality). After this I ran the following command:
env | grep DISPLAY
and found the following set on the server side via my SSH connection:
DISPLAY=localhost:10.0
This, I believe, is working normally. As this is the second box I’ve
tried after seeing your thread I’m led to believe this is either an odd
issue with Putty or is related to how you are installing OpenSUSE.
Good luck.

I runing with GNOME desktop. I get:
afeher@web:~> env | grep DISPLAY
afeher@web:~>
I try an other computer too, and it is OK. I can connect locally and get DISPLAY setting correctly.
So I try reinstall again. I think, the error in an other package.
I installed again with the default programs, default KDE desktop, and after updated. Still OK.
So the error in an other package…
Many thanks for the HELP…
