Re: Strange Network Traffic using -sP flag in nmap 3.81

| I think I may have discovered a bug nmap 3.81 - wasn't sure whether
| nmap-hackers or nmap-dev was a better place for this, so I've opted
| for here. When issuing a scan specifying either a single port or
| multiple ports with the '-p' flag, there's a connection made and then
| quickly reset to the destination host on port 80.

I believe that is nmap doing it's TCP ping of the host.  Try using
-P0, which tells nmap not to ping the host before scanning.

HTH,

Rick
