Wireshark-Network packet analysis software
The function of the network packet analysis software is to retrieve the network packet and display the most detailed network packet information as far as possible. Wireshark uses WinPcap as an interface to exchange data messages directly with the network card.
Network administrator uses Wireshark to detect

I've wanted to do this before, but I haven't been able to get the Internet data
By default, the root permission is required to access the network port, while Wireshark only requires a UI of/usr/share/dumpcap, and/usr/share/dumpcap requires the root permission, therefore, non-root users cannot read the NIC list.
The solution is simple. sudo Wireshark
However, Wireshark does not officially recommend this:
Running as user "root" and group "roo
Wireshark, formerly known as ethereal, is an amazing network monitoring tool. It helps you to capture the data packets being sent/received by your network interface and analyze it.
Warning:Before using Wireshark in promiscuous mode
Make sure that you have the required permissions to do so. promiscuous
Mode, in a way, is packet sniffing and might be able to get rid of

Write a Wireshark plug-in for private protocols
A Wireshark plug-in is written for the company's private protocol. In this way, we can intuitively analyze the captured packages and make development and debugging easier.
First, Wireshark compilation is quite difficult. There are also a lot of errors referring to the net text and the official developer guide of

Wireshark Packet Analysis data EncapsulationData encapsulation refers to the process of encapsulating Protocol data units (PDUs) in a set of protocol headers and tails. In the OSI seven-layer reference model, each layer is primarily responsible for communicating with peers on other machines.

Grab BagCapture extracts the package from the network adapter and saves it to the hard disk.Access to the underlying network adapter requires elevated privileges, so the ability to grab packets from the underlying NIC is encapsulated in Dumpcap, the only program in Wireshark that requires privileged execution, and the rest of the code (including parsers, user interfaces, and so on) requires only normal user rights.To hide all underlying machine dep

For application recognition, data traffic generated by applications is often analyzed.
Wireshark is used to capture packets. When extracting features, session filtering is required to find the key stream. The basic syntax of Wireshark filtering is summarized here for your reference. (My mind cannot remember anything)

Use Wireshark to analyze ICMP Packets
ICMP protocol Introduction
1. ICMP is the abbreviation of "Internet Control Message Protocol" (Internet Control Message Protocol. It is a sub-Protocol of the TCP/IP protocol family. It is used to transmit control messages between IP hosts and routers. A message control refers to a message of the network itself, such as network connectivity, host accessibility, and routing availability. Although these control messa
