Re: Nmap oprions

        Hi,

        Try this:

        nmap -p21 <net> | grep -B 2 open

        Now, if you want only IP address, may be this can help:

        nmap -p21 <net> | grep -B 2 open | perl -ne 'if (/(\d+.\d+.\d+.\d+)/)
{ print "$1 \n" };'
        


        Regards,

        Hécber Córdova
