Nmap (Network Mapper) is a free and open-source utility for network discovery and security auditing.

Nmap runs on major operating systems with official binaries for Linux, Windows, and Mac OS X, and includes the Zenmap GUI plus Ncat, Ndiff, and Nping for visualization, data transfer, comparison, and packet analysis.
