Nmap Development: Re: Can i tell nmap what to log and what not?

[Ron <iago () valhallalegends com>]

If you know what ports are going to be open before hand, then you can 
use the -p option on nmap (nmap -p 1-80,135,137).  However, if you know 
which ports are going to be open, that rather defeats the purpose of a 
portscan.
