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.Įasy: While Nmap offers a rich set of advanced features for power users, you can start out as simply as "nmap -v -A targethost". Powerful: Nmap has been used to scan huge networks of literally hundreds of thousands of machines. This includes many port scanning mechanisms (both TCP & UDP), OS detection, version detection, ping sweeps, and more. In addition to the classic command-line Nmap executable, the Nmap suite includes an advanced GUI and results viewer (Zenmap), a flexible data transfer, redirection, and debugging tool (Ncat), and a utility for comparing scan results (Ndiff).įlexible: Supports dozens of advanced techniques for mapping out networks filled with IP filters, firewalls, routers, and other obstacles. Nmap runs on all major computer operating systems, and official binary packages are avalable for Linux, Windows, and Mac OS X. It was designed to rapidly scan large networks, but works fine against single hosts. 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. Many systems and network administrators also find it useful for tasks such as network inventory, managing service upgrade schedules, and monitoring host or service uptime.
Nmap ("Network Mapper") is a free and open source (license) utility for network exploration or security auditing.
