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 nmap-sS-P0-sV-O -Ss tcp syn scan (also known as semi-open or stealth scan) -P0 allows you to Disable ICMP pings. -SV: Enable System Version Detection -O attempts to i

Author: dominate00 A few days ago, I saw someone posting for help in a bbs, which means what measures my server can take against or block Nmap scanning. At that time, I had limited ability to reply to the post. I didn't fully understand the principles of nmap functions, so I couldn't help. (After all, this is not a result of reading some materials or passing simple practical tests) I thought about it last

IntroducedPython-nmap is a port scanning tool based on the system Nmap command, which is simple and convenient to use.Recently, in order to enhance server security and supervision, it is necessary to keep the company server open port scan records every day, once there is an increase in the decrease can be found.Previously wrote a https://github.com/bashhu/monitor-shell/blob/master/python-script/scan_port.sh

High-speed discovery of feasible network hostsNMAP-SP 192.168.1.* eitherNMAP-SP 192.168.1.-2542, Scanning UdpportThe DP scan method is used to infer the condition of the udpport.Send a probe to the target host's udpport, assuming that the port is closed by receiving a reply to "ICMP Port unreachable", assuming that the response is not received, it means that udpport may be open or blocked. Therefore, the reverse exclusion method is adopted to determine which udpport are possible out of the op

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.

It can be said that if your network has a loophole, or your firewall has holes, or your server is open port, then your network is vulnerable to attack, the risk of damage. The first strike is strong. To prevent others from destroying their own network, first to their own "ruthless" point. We can use the method that the hacker uses to test our system first. 工欲善其事, its prerequisite. What tools should you choose? Here we recommend Nmap.
