Nmap help documentWhat is nmap? Nmap (Network ER) is an open-source Network detection and security audit tool. Its design goal is to quickly scan a large network. Of course, it is no problem to scan a single host with it. We recommend that you use ctrl + f for search. In fact, it is also convenient for you to remember at the same time For more information, see th

From http://nmap.orgHost discovery Host discovery is also called Ping scanning, but it is far more than sending simple ICMP echo request packets using a widely known ping tool. You can use list scan (-sL) Or by disabling Ping (-P0) Skip the ping step. You can also use multiple ports to combine tpc syn/ack, UDP, and ICMP. These probes aim to get a response to show whether an IP address is active (Host or network device ). If no host discovery option is provided,

After installing Linux, you will find that there will always be many application tools in Linux. The powerful use of these tools will make Linux network engineers and system administrators like it very much, such as the NMAP tool. The NMAP tool can be used to determine the network layout, ports opened by hosts, and services. This information is vital for administrators to improve system security.

1. Introduction Nmap is a network security tool for Network Discovery (network Discovery) and security audits (secure auditing), which is free software. The software name Nmap is the abbreviation of Network Mapper. Typically, Nmap is used to:Enumerate Network hosts listManage service Upgrade SchedulingMonitor HostService HealthNmap can detect whether the target m

Basic ScanBefore I go into the detailed explanation, I will try a simple scan and have a basic understanding of nmap tools.1.1Scan OverviewNmap The main tools are host survival Scan, port scan, NSE. The scan is divided into a single target scan (by specifying a single IP address/hostname), multiple target scans (by specifying multiple IP addresses/hostname), list scanning (creating a file to write IP address/hostname to). 1.2single target scanSingle t

NMap, also known as Network Mapper, is the Web scan and sniffer toolkit under Linux, with three basic functions, One is to detect whether a group of hosts is online; The second is to scan the host port, sniffing the network services provided; You can also infer the operating system used by the host. Nmap can be used to scan a LAN with only two nodes up to 500 nodes above the network.
