0x00 quickly learn about NmapNmap is a tool for scanning target network information, which can be used by hackers to detect host information and collect intelligence artifacts. It can also be a good helper for operators to scan the network environment and discover the system vulnerabilities in time.0x01 It's function650) this.width=650; "src=" Http://www.178linux.com/ueditor/php/upload/image/20150419/1429407123138187.png "title= "1429407123138187.png"

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
Network mapper (NMAP) is a powerful scanner that is often used in network security penetration testing. Below we will introduce several scanning parameters, mainly from the Internet:
1) obtain the system type and open port of the remote host

scan, check the host online or not, do not send any message to the destination host, want to know whether the target host is running, and do not want to do other scans, this scanning method is very common)2,-SL (only in the network segment out of the host State, port and other information, query port words with-p port
active only scans the port for an instant, and only the services used at that time are likely to be detected.
3-port scanning is a generalized attack behavior, for the last licensed machine, generally can not be implemented.
The advantages of passive
Passive only listens to the network, does not become the network attack, it runs for a long time, can detect the change of the server within a long interval.
This article provides thought-based usage: about the automatic detection feature, the various ports and the capture function, the project used for Nmap software, Linux operating system, first we want to install NMAP software project used in the nmap-6.40-7.el7.x86_64 version,The command format is: #nmap [
