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 i

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

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
