A result of "closed" means the > port is being actively blocked and a message is being sent to tell you > that it is. A result of "filtered" means that the port is not > responding to say whether it is open or not.

That > what the ":1" or ":2" mean when you set up the entries in the > /etc/sysconfig/vncserver file. This also means that to connect to a vnc > server set up for ":2" on the example IP address above you need to use > "192.168.1.10:2" in the vncviewer and the nmap output from probing the > target system should show that port 5902 is open.
