NMAP provides four basic functions (host discovery, port scanning, service and version detection, OS detection) and a rich scripting library. Nmap can be used for simple network information scanning, but also in high-level, complex, specific environment: such as scanning a large number of hosts on the Internet, bypassing the firewall/ids/ips, scanning web sites, scanning routers and so on.Briefly review

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 ).

A scanner is a program that can automatically detect the vulnerabilities of a host's security. The scanner collects all kinds of information about the target host by sending a specific network packet, recording the response message of the target host. At present, there are many scanning software on the network, more famous scanners have Sss,x-scan,superscan and so on, the function is most powerful of course is nma

Whenever I infiltrate the Intranet to face a large number of hosts and services, I am always accustomed to using automated methods to extract information from the NMAP scan results. This facilitates automated detection of different types of services, such as path blasting of Web services, testing of keys or protocols used by the SSL/TLS service, and other targeted testing.
I also often use Ipthon or *nix
This article describes how to use a line of code to parse nmap scan results. the NmapParser Library in libnmap is used in the Python environment, this library can easily help us parse nmap scan results. Whenever I perform intranet penetration for a large number of hosts and services, I am always used to extracting info
NMap, also known as Network Mapper, is a web scan and sniffer toolkit under Linux. Nmap is a powerful scanner that is often used in network safety penetration testing. The power of function is self-evident. Here are some of its scanning commands. Specifically, we have to rely on everyone to learn, because it is too strong. 1) Get the system type and open po
