Connecting to VNC on a guest without X on it.

Scenario :


Hostname

Host OS -host1
Host1 has 2 IPs 10.xx.xx.xx  and 192.xx.xx.xx

eth0:  10.222.22.2  can connect from my windows desktop
eth1:  192.168.5.2 is used to connect to Guest os

Guest OS - Guest1 
Guest has IP address 192.168.2.1

SSH Port fowarding is one one way to connect :

On host os do fowarding to Guest OS.
Flush Rules First
#iptables -t nat -F


Port forwarding from Host1:6001(host os) to 192.168.2.1:6001 (guest os)

#/sbin/iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE

#iptables -t nat -A PREROUTING -p tcp -s 0.0.0.0/0  -d 10.222.22.2 --dport 6001 -j DNAT --to-destination 192168.2.1:6001


WAY 2

Export display of guest to host where you have X running:

on Guest  OS if you dont have X running and want to use a X of different server.
#export DISPLAY=host_where_x_is_running:1.0
#vncpasswd (set password)

#xterm &

From windows desktop vnc connect to  guest it will forward its display to [ host_where_x_is_running ]
