I am using nmap to create a list of targets that I

Will
nmap -sP still find the systems if ping does not?
I have something just for you; I use it constantly
during assessments
just for this purpose:
nmap -vv -n -sP
-PS21,22,23,25,53,80,110,135,139,143,445,1433,1521
$target | grep appears | grep up | cut -d" " -f2 >
$outfile
What this does is "ping" the host via not just ICMP,
but also via TCP
connections on the ports listed. :) It makes great
lists and, as you
know, it saves tons of time when you import a list
of active hosts
instead of just feeding a network.
Hope you like it. :) Oh, and here's my Nmap "Primer"
which has a
couple other decent nuggets:
