Wireshark is a grab package software, more easy-to-use, in the usual can use it to grasp the package, analysis protocol or monitoring network, is a better tool, because recently in the study of this, so write a tutorial to facilitate everyone to learn.

). TCP provides high reliability data communication for two hosts. His work involves dividing the data that the application gives to it into appropriate chunks to the network layer below, confirming the packets received, setting the timeout clock for sending the last confirmed packet, and so on. Because the transport layer provides high reliability end-to-end communication, the application layer can ignore all of these details. UDP, on the other hand, provides a very simple service for the appli
The new version of Wireshark can parse NB-IoT cell messages, and of course the stored message formats need to be converted to the. pcap format Wireshark can parse. The analytic format of Wireshark can be used to understand the protocol flow and the meaning of individual cells. Wireshark Setup Preparation 1, edit-by pre

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
Working with WebSocket technology, the use of the process found that the browser (Chrome) after the upgrade may cause the WebSocket is not available, the browser can be changed after the normal use.Once in a while, it is occasionally possible to debug locally, discovering that using the same version of the Chrome browser does not connect to the WS service on the online server, but can connect to the local WS service. The initial suspicion is that the server will trigger an unreachable problem in

The problem is that I didn't find such an option. I started to think that my Nic is not supported. I used a colleague's Acer computer to disable the nic vlan function and then I can capture packets.

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:

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.

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
