The primary documentation for using Nmap is the Nmap Reference Guide. This is also the basis for the Nmap man page (nroff version of nmap.1). It is regularly updated for each release and is meant to serve as a quick-reference to virtually all Nmap command-line arguments, but you can learn even more about Nmap by reading it straight through.

Including the -O -v options caused Nmap to generate the following extra line items: Device type All fingerprints are classified with one or more high-level device types, such as router , printer , firewall , or (as in this case) general purpose .

When an IP protocol scan is requested (-sO), Nmap provides information on supported IP protocols rather than listening ports. In addition to the interesting ports table, Nmap can provide further information on targets, including reverse DNS names, operating system guesses, device types, and MAC addresses.

当要求进行IP协议扫描时 (-sO)，Nmap提供关于所支持的IP协议而不是正在监听的端口的信息。 除了所感兴趣的端口表，Nmap还能提供关于目标机的进一步信息，包括反向域名，操作系统猜测，设备类型，和MAC地址。

Please read the Windows section of the Install Guide for limitations and installation instructions for the Windows version of Nmap. It's provided as an executable self-installer which includes Nmap's dependencies and the Zenmap GUI. We support Nmap on Windows 7 and newer, as well as Windows Server 2008 R2 and newer.

2017年9月1日 · In addition to the classic command-line Nmap executable, the Nmap suite includes an advanced GUI and results viewer , a flexible data transfer, redirection, and debugging tool , a utility for comparing scan results , and a packet generation and response analysis tool .

O Nmap (“ Network Mapper ”) é uma ferramenta de código aberto para exploração de rede e auditoria de segurança. Ela foi desenhada para escanear rapidamente redes amplas, embora também funcione muito bem contra hosts individuais.

Nmap utiliza paquetes IP "crudos" («raw», N. del T.) en formas originales para determinar qué equipos se encuentran disponibles en una red, qué servicios (nombre y versión de la aplicación) ofrecen, qué sistemas operativos (y sus versiones) ejecutan, qué tipo de filtros de paquetes o cortafuegos se están utilizando así como docenas de ...

One of Nmap's best-known features is remote OS detection using TCP/IP stack fingerprinting. Nmap sends a series of TCP and UDP packets to the remote host and examines practically every bit in the responses.

For that, we released Nmap Network Scanning: The Official Nmap Project Guide to Network Discovery and Security Scanning. Topics include subverting firewalls and intrusion detection systems, optimizing Nmap performance, and automating common networking tasks with the Nmap Scripting Engine.
