I wonder how difficult it would be to port the Apache DOS Evasive Maneuvers module to an inetd implementation. It does an excellent job of both fending off Dos/DDoS/Brute Force attacks and it also will talk to other tools on the network (Firewall, Router) to push the attack back to the borders. I would love a stab at doing this, but does anyone know where the original inetd source tree could be found? You could theoretically do this to the wrappers instead, but with consequences...so it makes more sense to code it right into the inetd listener. For reference the Apache DOS Evasive Maneuvers Module can be found at http://www.nuclearelephant.com/projects/dosevasive/ The advantage to doing it this way is that nothing goes into 'queue' mode, and nothing shuts down...you're cutting off the flooding host (or hosts) and nobody else. It would be all too easy to detect an inetd flood.
