nmap 4.01 on xp

["R M" <rmtechnet () gmail com>]

hi,

I am running nmap 4.01 on an xp service pack 2 machine.

when I run 'nmap -PS 10.0.0.2', isn't it only supposed to send an TCP
packet with SYN set to port 80?
 And if I run 'nmap -PS22 10.0.0.2', it should only send the same to
port 22 only, correct?

When I look at either of the above ping scans using ethereal, I see
that in both cases a SYN is being sent to all ports at the destination
(and not just one port or the port number that I specified). Is this
is a known issue or am I missing something here ??

btw, 10.0.0.2 is in the same network as the machine running nmap.

thanks, folks!

Rosh
