RE: nmap -S option

["Earl Carter (ecarter)" <ecarter () cisco com>]

Baris,

If you specify a spoofed address, then replies from the target being
scanned go to the spoofed address. If you machine can not see those
replies, nmap can not determine the open ports. If you specify an
address (other than your machine's address), then you need to make sure
that you can see the replies to perform accurate scanning.

Earl :)
