The Design and Implementation of laffer1

o 30+ new Nmap Scripting Engine scripts
o enhanced performance and reduced memory consumption
o protocol-specific payloads for more effectie UDP scanning
o a completely rewritten traceroute engine
o massive OS and version detection DB updates (10,000+ signatures)

This looks awesome. In case you're not familiar with nmap, it allows you to scan a host to determine the OS it is running and look for services by way of a port scan.
