Hping is a net tool, it can be used to analyse networks and hosts.
        In the beginning hping was only for Linux. Now i'm porting it
        to other platforms:

                BSDi
                FreeBSD
                Solaris
                HP-UX

        Versions 0.7x are libpcap based portings *** very instable ***.
        Versions 0.6x are more stable, only for Linux.

        All this version will converge in stable, platform indipendent,
        more powefull version: 1.0

        Have fun!
