From the README: This program is designed to log smurf attacks and the broadcasts used. Essentially it is just an icmp echo reply logger with the following twists: - Logging only begins after passing a certain threshold rate of packets/sec and kilobytes/sec. This prevents the logging of innocent ping replies. - Only the /24 is logged, and it is only logged once per attack. Jacques Vidrine <nectar@FreeBSD.ORG>
