nmap


Nmap is a utility for network exploration or security auditing. It

supports ping scanning (determine which hosts are up), many port

scanning techniques, version detection (determine service protocols

and application versions listening behind ports), and TCP/IP

fingerprinting (remote host OS or device identification). Nmap also

offers flexible target and port specification, decoy/stealth scanning,

sunRPC scanning, and more. Most Unix and Windows platforms are

supported in both GUI and commandline modes. Several popular handheld

devices are also supported, including the Sharp Zaurus and the iPAQ.

The Paketto Keiretsu is a collection of tools that use new and unusual

strategies for manipulating TCP/IP networks. scanrand is said to be

faster than nmap and more useful in some scenarios.

This package includes:

* scanrand, a very fast port, host, and network trace scanner

* minewt, a user space NAT/MAT (MAC Address Translation) gateway

* linkcat(lc), that provides direct access to the network (Level 2)

* paratrace, a "traceroute"-like tool using existing TCP connections

* phentropy, that plots a large data source onto a 3D matrix
