SubjectRe: No more DoS
Date
Not only is this a well written article, and clearer than most other 
documents (Even Mine :>) but he is dead on track with his basic concepts..
Exactly what I have been looking into over at our company. (Well, close
enough)

The concept of trusting a SYN packet, has to go.. we have to assume that it
is false/bad, and only after receiving the ACK in reply to our SYN/ACK can we
start assuming that the previous packets were good..

All IMHO.... Nice find and a good read for anyone..
I am CC'ing the netfilter list as they might like the read.. in case they
haven't read it. (Surprised I haven't seen more discussion on this topic)
