RV: nmap -S option

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
