how to use nmap

Nmap is a command line network detection tool. It is the most commonly used security scanning tool in Linux, classic. This feature supports ping scanning to determine the online host, port scanning technology, and TCP/IP remote device fingerprint recognition. The latest available version is NMAP 4.46.1 and has been released recently. Recommended reading: Port scanning tool

1. My environment is Windows XP sp3. When I use nmap to scan the Internet, I am prompted Pcap_open_live (ppp0, 100, 0, 2) FAILED. Reported error: Error opening adapter:The system cannot find the specified device. (20). Will wait 5 seconds then retry. Looking at the nmap manual, Microsoft has disabled raw sockets since Windows XP SP2. Therefore, you need to add

Many network services use Linux systems and have Apache Server software installed. Vulnerable to hackers using Nmap to scan Web sites, now share a precautionary experience.I can pass the setup, let Linux on Nmap scan ignore color. The iptables tool is used to filter the network information so that the system cannot respond to the scan request information. To impr

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

reserved and private IP addresses included in RFC3927 and removed the 6/8, 7/8, and 55/8 networks. A function is added to determine whether the target ip address belongs to a private ip address. The scan target can be randomly generated by filtering-iR. To avoid these problems, you can use a custom method or import a list from a file.23. The-4 option is used to specify the ipv4 protocol for scanning (this is the default scan method), but

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.
