Re: [ANNOUNCE] protocol watcher
From: Justin Pryzby <justinpryzby(at)users.sourceforge.net>
Date: Thu May 22 2003 - 15:23:30 EDT This is noted in the README. I have recommended that people use it only on dedicated "honeypots", or at least on client machines, rather than on mission-critical servers :) One can always use iptables --rate, but, like I said, I'm unable to tests it very well atm. I think that, as written, synfloods are equivalent to fork bombs (very bad because now people don't even need a shell account); but it's my list of things to do: make the accept() non-blocking, and if a response isn't heard within $TIME then log the attack, which is known to be a SYN attack! This both avoids the fork bomb and notifies the admin of the (special) attack. Non-SYN attacks are also bad, but the primary problem is disk access and disk space.
