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 Job you currently have. (In simpler wor

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
