In CentOS 4 does anyone know the switches to get NMAP to reveal the
MAC of the host being scanned ?
I cant seem to find it and i am using nmap-4.20 - i am sure this was
available somehow on older releases.
MAC address is only available on the same network segment... And, I've
noticed hte newer versions of nmap only seem to show it if you run it as
root....
