Nmap: Discover your network

Nmap ("Network Mapper") is afree and open source utility fornetwork discovery and security auditing. Many systems and networkadministrators also find it useful for tasks such as networkinventory, managing service upgrade schedules, and monitoring host orservice uptime. Nmap uses raw IP packets in novel ways to determinewhat hosts are available on the network, what services (applicationname and version) those hosts are offering, what operating systems(and OS versions) they are running, what type of packetfilters/firewalls are in use, and dozens of other characteristics. Itwas designed to rapidly scan large networks, but works fine againstsingle hosts. Nmap runs on all major computer operating systems, andofficial binary packages are available for Linux, Windows, and Mac OSX. In addition to the classic command-line Nmap executable, the Nmapsuite includes an advanced GUI and results viewer(Zenmap), a flexible datatransfer, redirection, and debugging tool(Ncat), a utility forcomparing scan results (Ndiff), and a packet generation and response analysis tool (Nping).

Nmap was named “Security Product of the Year” by LinuxJournal, Info World, LinuxQuestions.Org, and Codetalker Digest. Itwas even featured intwelvemovies, includingThe Matrix Reloaded,Die Hard 4,Girl With the Dragon Tattoo, andThe Bourne Ultimatum.
