This is hilarious.
As of 23 Sep 2008, the hping home page at http://www.hping.org/ says:
"Hping works on the following unix-like systems: Linux, FreeBSD, NetBSD, OpenBSD, Solaris, MacOs X, Windows."
For the really obtuse, I really didn't realise that Windows is a unix-like system. *grin*
That said, hping is a great utility,and I'm really being a moronic idiot here.
