Nmap is a security scanner originally written by Gordon Lyon (Fyodor). It may be used to discover computers and services on a computer network, thus creating a "map" of the network. Just like many simple port scanners, Nmap is capable of discovering passive services on a network despite the fact that such services aren't advertising themselves with a service discovery protocol. In addition Nmap may be able to determine various details about the remote computers. These include operating system, device type, uptime, software product used to run a service, exact version number of that product, presence of some firewall techniques and, on a local area network, even vendor of the remote network card.
Typical uses of Nmap:
Various web-based interfaces have also been available for controlling Nmap remotely from a web browser. These include LOCALSCAN, nmap-web, and Nmap-CGI.
System administrators often use Nmap to search for unauthorized servers on their network, or for computers which don't meet the organization's minimum level of security.
Nmap is often confused with host vulnerability assessment tools such as Nessus, which go further in their exploration of a target by testing for common vulnerabilities in the open ports found.
The appearance of Nmap in the film was widely discussed on internet forums , and hailed as an unusually realistic example of hacking compared to other movies It is thought that Trinity used the CRC32 compensation attack detector exploit (discovered in 2001) to gain entry, once Nmap revealed the existence of an SSH service
Nmap and NmapFE were used in The Listening, a 2006 movie about a former NSA officer who defects and mounts a clandestine counter-listening station high in the Italian alps.
Some Nmap source code can be seen in the movie Battle Royale
