Hello all,
i'm doing a reseach on scanning techinues
I'm looking for the hping2 command that you can use to determine if a port is opened by analysing the TTL field and the window field in the header packet.
i saw a sample in chris mcnab's book but it didnt give me the sample

i'm using the following sceanio. i have a windows 2000 professional, win xp and unix system all running onthe same network. then i manually opened 2 ports from the windows xp computer. so what hping command shd be used from the unix.

since i know that windows 2k dsnt have any firewall settings in it, that means all ports should be opened. so how do i scan it using hping2 too

you'd have to download hping2 and see if it includes a man file to help you with the syntax.
