That's pretty obvious. But in case of 18245>21536 packets, there's
almost no gain.. of course, you can send such packets to every IP in
my network and get me alarmed when you hit a machine which doesn't run
an HTTP server. Or you can just use them to OS-fingerprint HTTP
servers my firewall protects. But then - why don't you use port 80 for
your scans? It *is* open and probably you can also know if my firewall
filters are stateful or not. What more can you get from port 21536
scans?

Nice idea. :)

OK, nobody has to trust me. Or anyone. But it doesn't mean you can
assume anyone posting here to be a bad guy. Some people would lie
here, some'd just be wrong. But you know all this stuff, I won't
repeat. Just verify what you read here before trusting it.
