This is one way of identifying all hosts with port 21
open. The ipfile.txt should have a single IP address
on each line. The nmap.all will contain all output in
a grepable form.
nmap -sS -P0 -p 21 -oG nmap.all ./ipfile.txt
Then to identify which hosts had the open port
grep open nmap.all
Hope this helps.
