Nmap ("Network Mapper") is useful for tasks such as network inventory, managing service upgrade schedules, and monitoring host or service uptime.
Nmap supports ping scanning (determine which hosts are up), version detection (determine what application/service is runing on a port), many port scanning techniques (determine what services the hosts are offering), and TCP/IP fingerprinting.
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 was designed to rapidly scan large networks, but works fine against single hosts. Nmap runs on all major computer operating systems, and both console and graphical versions are available.
Here are some key features of "Nmap":
· Flexible: Supports dozens of advanced techniques for mapping out networks filled with IP filters, firewalls, routers, and other obstacles. This includes many port scanning mechanisms (both TCP & UDP), OS detection, version detection, ping sweeps, and more. See the documentation page.
· Powerful: Nmap has been used to scan huge networks of literally hundreds of thousands of machines.
· Portable: Most operating systems are supported, including Linux, Microsoft Windows, FreeBSD, OpenBSD, Solaris, IRIX, Mac OS X, HP-UX, NetBSD, Sun OS, Amiga, and more.
· Easy: While Nmap offers a rich set of advanced features for power users, you can start out as simply as "nmap -v -A targethost". Both traditional command line and graphical (GUI) versions are available to suit your preference. Binaries are available for those who do not wish to compile Nmap from source.
· Free: The primary goals of the Nmap Project is to help make the Internet a little more secure and to provide administrators/auditors/hackers with an advanced tool for exploring their networks. Nmap is available for free download, and also comes with full source code that you may modify and redistribute under the terms of the license.
· Well Documented: Significant effort has been put into comprehensive and up-to-date man pages, whitepapers, and tutorials. Find them in multiple languages here.
· Supported: While Nmap comes with no warranty, it is well supported by the community and we appreciate bug reports and patches. If you encounter a problem, please follow these instructions.
· Acclaimed: Nmap has won numerous awards, including "Information Security Product of the Year" by Linux Journal, Info World and Codetalker Digest. It has been featured in hundreds of magazine articles, several movies, dozens of books, and one comic book series. Visit the press page for further details.
· Popular: Thousands of people download Nmap every day, and it is included with many operating systems (Redhat Linux, Debian Linux, Gentoo, FreeBSD, OpenBSD, etc). It is among the top ten (out of 30,000) programs at the Freshmeat.Net repository. This is important because it lends Nmap its vibrant development and user support communities.
Requirements:

What`s New in This Release: [ read full changelog ]
· [Ndiff] Added support for prerule and postrule scripts. [David]
· [NSE] Fixed a bug which caused some NSE scripts to fail due to the absence of the NSE SCRIPT_NAME environment variable when loaded. Michael Pattrick reported the problem. [Djalal]
· [Zenmap] Selecting one of the scan targets in the left pane is supposed to jump to that host in the Nmap Output in the right pane (but it wasn`t). Brian Krebs reported this bug. [David]
· Fixed an obscure bug in Windows interface matching. If the MAC address of an interface couldn`t be retrieved, it might have been used instead of the correct interface. Alexander Khodyrev reported the problem. [David]
· [NSE] Fixed portrules in dns-zone-transfer and ftp-proftpd-backdoor that used shortport functions incorrectly and always returned true. [Jost Krieger]
· [Ndiff] Fixed ndiff.dtd to include two elements that can be diffed: status and address. [Daniel Miller]
· [Ndiff] Fixed the ordering of hostscript-related elements in XML output. [Daniel Miller]
· [NSE]...
