All, New on the list, I've started working with IPv6 and the security tools for the protocol. The problem I come to you all with is nmap, from a windows 2003 box to windows 2003 box using the -PS option I get 3 packets per ports scanned, the scan takes 921 seconds for ports 1-1024 on a single host.
