Connecting to my Linux lab machine with VNC.

VNC

Machines on the same internal network, same subnet

1. Download and Set up VNC server on the host machine.  The host is the machine you want to connect to.
2. Download VNC viewer on machine you want to connect from.
3. On machine you want to connect from, run VNC viewer.
4. Type in the ip address of the host.
5. ERROR:  No route to host.  This looks like a problem with iptables.  After reading a little, iptables is a firewall installed by default with Linux.  Next I need to read about either disabling iptables or adding my VNC port to this table.  
1. I disabled iptables and this worked.
2. service iptables stop
6. voila!

Things to note:

1. If you are connected to vpn then you should connect on both machines.  If you don't then you will not be able to connect to the guest from the host.
