Nmap 7.95

Nmap is a free and open source utility for network discovery and security auditing. It is a powerful tool that is used by many systems and network administrators for tasks such as network inventory, service upgrade scheduling, and host or service uptime monitoring. Nmap uses raw IP packets to scan networks and determine what hosts are available, what services are being offered, what operating systems are being used, and a variety of other characteristics. It is designed to scan large networks quickly, but it is also effective against single hosts.

Nmap is available for all major operating systems and official binary packages are available for Linux, Windows, and Mac OS X. In addition to the classic command-line version, the Nmap suite includes an advanced GUI and results viewer (Zenmap), a flexible data transfer, redirection, and debugging tool (Ncat), a tool for comparing scan results (Ndiff), and a packet generation and response analysis tool (Nping).

One of the standout features of Nmap is its flexibility. It supports a range of advanced techniques for mapping out networks that are protected by IP filters, firewalls, routers, and other obstacles. This includes a range of port scanning mechanisms (both TCP and UDP), OS detection, version detection, ping sweeps, and more. It is a powerful tool that has been used to scan networks of hundreds of thousands of machines.

In addition to its powerful features, Nmap is also portable and easy to use. It is supported on a wide range of operating systems, including Linux, Windows, Mac OS X, and more. It is easy to get started with Nmap, as users can simply enter "nmap -v -A targethost" to begin a scan. Both traditional command line and graphical (GUI) versions are available, and binary packages are also available for those who do not want to compile Nmap from source.

Nmap is a free tool that is designed to help make the internet a little more secure. It is well supported by a vibrant community of developers and users, and is well documented with comprehensive man pages, whitepapers, tutorials, and even a book. It is available for free download and comes with full source code that can be modified and redistributed under the terms of the license.

Overall, Nmap is a powerful and versatile tool for network discovery and security auditing. It is suitable for use by systems and network administrators, as well as hackers and auditors who want to explore their networks. It is easy to use and well supported, and offers a range of advanced features for power users. If you are in need of a tool for network discovery and security auditing, Nmap is definitely worth considering.
