X11Forwarding - could not open display on headless server

Hello,

I'm trying to forward virt-manager running on a headless CentOS 6.5 server. The host has X11Forwarding yes and X11DisplayOffset 10 both uncommented in sshd_conf Also, the $DISPLAY variable on the headless server does not return anything. I'm guessing it's missing the display because when I execute the following command, I get the errors:

PHP Code:




$ ssh -X root@headless_srvr virt-manager 
root@headless_srvr's password:  
X11 forwarding request failed on channel 0 
Traceback (most recent call last): 
  File "/usr/share/virt-manager/virt-manager.py", line 383, in <module> 
    main() 
  File "/usr/share/virt-manager/virt-manager.py", line 286, in main 
    raise gtk_error 
RuntimeError: could not open display

I was wondering how can I setup X11Forwarding over SSH from a headless server to a host running an OS with Gnome.

Thank you in advance!

Try to set

Quote:

X11DisplayOffset 10

as commented and

Quote:

X11UseLocalhost no

as uncommented.

Did you restart ssh daemon after making changes in sshd_confing?

If you are still facing problem, try to install following packages.

yum install xorg-x11-xauth

Hi,

Thanks for the reply. I set "X11UseLocalhost no", installed the package and restarted the service and now it works! Thank you! I'm not sure if it's the setting or the package but it works now!
