Subject: hashlimit match : how is that to use hop count as the hash info?
Date: Sat, 1 Sep 2007 15:16:45 +0900 [thread overview]
Message-ID: <006601c7ec5f$ac158c10$0be810d2@JULIE> (raw)
Hi,
Is it possible to use hop count (TTL) as the hash value?
I can’t find the way to defend against spoofing based DDoS attacks.
If the hop count and destination ip and destination port is used as hash value, it seems to be effective to defend against spoofing based DDoS attacks,
because the attacker do not spoof the hop count, and TTL value is of most packets will be different.
Sorry for my poor English!
