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

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

In Linux, use the nmap command-general Linux technology-Linux technology and application information. The following is a detailed description. Prerequisites:
Generally, netstat is recommended when you view the port on the local machine because it is secure and reliable. If you cannot find the port or do not know what the port is, the nmap command can be used, especially for the service corresponding to the

The following experiment is used to reproduce the problem:
A Windows xp2 virtual machine is installed locally and the firewall is enabled. 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 Machine XP.

The nmap port status resolution is open, on which the application receives TCP connection or UDP packets. The port closed by closed is also accessible to nmap. It receives and responds to nmap detection packets. But no application listens on it. Filtered Because packet filtering prevents the probe packet from arriving at the port,
Nmap source code learning 1 download and compilationIntroduction
Nmap is an open-source free scanning tool. Learning its source code can help you better understand the basic knowledge of the network. I have never had a deep understanding of the network, but I have previously used c to write a program for detecting operating system fingerprints. Now, in order to learn more about network security, we have de
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.

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, and ICMP. It supports: vanilla TCP connect sc
