how to use nmap

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 port of the remote host 　　

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

Therefore, the reverse exclusion method is adopted to determine which udpport are possible out of the op

Run the netstat command in the virtual machine to view the port status: Run the command netstat-An to obtain the following results: At the same time, use nmap6.00 on the local PC to scan the UDP port of the Virtual

Linux has a lot of powerful network scanning tools, network scanning tools can be divided into: host scanning, host service scanning, route scanning and so on.Prior to the usual host scan and route scanning tools, NMAP supports bulk host scanning and host service scanning.Installation of Nmap directly using: Yum install Nmap.The ICMP scan of Nmap

I often use it to detect the remote Windows Server IP address, because it is not a fixed IP address, the server's IP address will often change, but there is a rule, only within a network segment changes, so that the determination of IP address to bring convenience.1.

[Original] Introduction to NMAP network port scanning tools I NMAP Introduction NMAP is a port scanning tool for large networks, although it is also suitable for single-host scanning. In different situations, you may need to hide, scan across the firewall, or use different protocols for scanning, such as UDP, TCP,

NmapBasic KnowledgeNmap is a free and open network scan and sniffer kit, also known as Network Mapper (Mapper). The Nmap tool can be used to scan the ports developed on the computer, determine which services are running on which ports, and infer which computer is running from the operating system. By using this tool, you can evaluate the security of your network system, so nmap is a necessary tool for most

Four layers found that the purpose of four layer discovery is to scan out the possible IP address, four layer discovery, although involving port scanning, but does not accurately judge the status of the port, its essence is to use some of the four layer protocol communication to identify the existence of host IP. Four-layer Discovery benefits: 1, can be routed and reliable results; 2, is not likely to be filtered by the firewall,
