Re: [Xen-users] Vnc unable to open Display on xen CentOS


using "ssh -X" should be enough. Another way is to edit
/etc/ssh/ssh_config, look for ForwardX11
I have done a lot of things which have not worked one of them being following 
I followed this one http://wiki.centos.org/HowTos/VNC-Server

 ssh root@xxxxxxxxxxxx -L 5901:localhost:5901
root@xxxxxxxxxxxx’s password:
bind: Address already in use
channel_setup_fwd_listener: cannot listen to port: 5901
Could not request local forwarding.

Other way which I tried was
From the CentOS Wiki http://wiki.centos.org/HowTos/VNC-Server
I read and did
Here is what I did
added a user tapas  on 192.168.1.10
for using vnc


VNCSERVERS="1:tapas"
VNCSERVERARGS[1]="-geometry 640x480"
also did # service vncserver start
went to /home/tapas/.vnc and edited
xstartup
removed the comment from these two lines
unset SESSION_MANAGER
exec /etc/X11/xinit/xinitrc
also added following lines to the start of the file
( while true ; do xterm ; done ) &
So that xterm session is available
restarted vncserver
service vncserver restart



But VNC Server is running which we can verify from the following outcome

vncext: VNC extension running!
vncext: Listening for VNC connections on port 5902
vncext: Listening for HTTP connections on port 5802
vncext: created VNC server for screen 0
