It needs clarification. > I read over the ``manual page'' &Keramidas.use-manual-page.not-man-page; and I gather this as more a method for port scans. Can this method be used WITH ipfw(8)? If so, then wouldn't it be eaiser to use this feature. I do think you can use it like that, but i'm not sure... paragraph 1 states that setting the value to 2 will drop connections on a closed port... makes me think that ipfw(8) could forward packets and this could be ran along side... But with no experiance with blackhole(4) i'd rather hear another comment... -- Tom (Darklogik) Rhodes www.Pittgoth.com Gothic Liberation Front www.FreeBSD.org The Power To Serve To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-doc" in the body of the message
