The Wireshark software is installed on the computer today, and when interface is set, "There is no interfaces on which a capture can is done" prompts that no one network interface is ready. This hint is obviously wrong, my network card is clearly able to surf the internet, how is the Internet interface not ready? I think it should be related to the normal user rights under Linux. Google on the internet a bit, found a solution to the problem, now sorte

Non-standard port numbers are always the most common concern of network analysis experts. Check whether the application intends to use a non-standard port, or secretly want to try to use the firewall. This document selects
To make a long story short, Wireshark has a follow TCP stream feature, which is handy. The drawback is that the extracted stream data does not have time stamps and other information, in the analysis of data delay and packet loss is somewhat inadequate. In this case, a simple follow TCP stream function is implemented with Python, while the TCP information is preserved.The principle is simple and is still based on W
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.
