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. --- Juan B <juanbabi@yahoo.com> wrote:
