From nmap web site (www.insecure.org) :"Another possible use of this flag (-S)
is to spoof the scan to make the targets think that someone else is scanning
them. Imagine a company being repeatedly port scanned by a competitor! The -e
option and -P0 are generally required for this sort of usage. Note that you
usually won't receive reply packets back (they will be addressed to the IP you
are spoofing), so Nmap won't produce useful reports"

Asunto: nmap -S option
Hello,
When i use "nmap -sS targetaddress -S spoofaddress -e eth0" command, nmap does
not show open ports at end of scan.
i wanna know whether this is normal case or not.
do i misuse nmap options?
Because when i use nmap with "nmap -sS targetaddress", nmap shows me open ports
at the end of scan.
Thanks,
Kind regards,
Baris Erdogan
