I have 3 NIC's in my machine.
If I do a nmap -sU (UDP Scan) on all my IP addresses it shows port 177 (XDMCP) open on all 3 IP addresses.
What I'd like to do is for port 177 to be open on just one of my ip addresses and it closed on the other 2 ip addresses is this possible and how is this acheived?
using tightvnc and gnome (gdm)
thanks in advance
