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

1. 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
Wireshark decoding display of ping messages (be and LE)We are very familiar with the package structure of the ping message, but in this message decoding we find that the decoding of Wireshark has several parameters: Identifier (BE), Identifier (LE), Sequence number (BE), Sequence Number (LE), as shown in:Never notice wireshark is such decoding ping message, it fe

TCP relative sequence numbers TCP Window Scaling
By default Wireshark and tshark will keep track of all TCP sessions and convert all sequence numbers (SEQ numbers) and acknowledge numbers (ACK numbers) into relative numbers. this means that instead of displaying the real/absolute seq and ACK numbers in the display, Wireshark will display a seq and ACK number relative to the first seen segment for that con
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)
Wireshark can be divided into protocol filter
Under Linux, when we need to crawl network packet analysis, we usually use the Tcpdump crawl Network raw packet to a file, and then download it locally using the Wireshark Interface Network analysis tool for network packet analysis.Only recently found that the original Wireshark also provided with the Linux command line tool-tshark. Tshark not only has the function of grasping the package, but also has the
First, you need to install two dependencies:

$ sudo apt-get install Qt4-default
Second, download the Wireshark 1.12.2 installation package:

At the time of downloading, I am prompted with the following error:

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.
