Can't Open Display - X11 Forwarding - Cent OS

  • 772

Trying to access X11 my CentOS 6 x32 small Linode VPS through SSH Putty/Xming (enabled X11 forwarding on options).

My windows machine is not the problem since it works with others CentOS Servers.

X11Forwarding is enabled on /etc/ssh/sshd_config, still I can't get X11 forwarding.

I'm trying to get xclock to work, but I get Can't open display :0.0 error.

I've also tried with different $DISPLAY values like :0 or :10.0

I've tried MobaXterm, and I get this message when connecting:

X11 forwarding request failed on channel 0

    Here (Red Hat Login required) is a Tech Brief article from a fellow Red Hat consultant which discusses the minimum packages needed for X-Windows to work for SSH connections.

    The key points are: 

    1) Install the following:
xorg-x11-xauth
xorg-x11-fonts-*
xorg-x11-utils
2) Enable the following in the sshd_config file
X11Forwarding yes
3) Use an appropriate X-Server on your desktop
