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

Got solution from here.

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 getCan'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
