1. Nmap

I think everyone has heard of this one, recently evolved into the 4.x series.

Nmap (”Network Mapper”) is a free open source utility for network exploration or security auditing. It was designed to rapidly scan large networks, although it works fine against single hosts. Nmap uses raw IP packets in novel ways to determine what hosts are available on the network, what services (application name and version) those hosts are offering, what operating systems (and OS versions) they are running, what type of packet filters/firewalls are in use, and dozens of other characteristics. Nmap runs on most types of computers and both console and graphical versions are available. Nmap is free and open source.

Can be used by beginners (-sT) or by pros alike (–packet_trace). A very versatile tool, once you fully understand the results.

These tools, like many network utilities, can cause crippling performance and other damage to the hosts and networks they run against. Because of this, some anti-virus software may identify these tools as denial of service (DoS) agents, Trojans, back doors or other forms of virus.**
