In fact, this problem is often found during packet capture. Today I went to Google with curiosity.
In a simple summary, the packet captured by Wireshark prompts a checksum error,It is only because it intercepts the overhead checksum of the operating system, and the Gigabit NIC will hand over the computing work to the NIC after enabling checksum offload, the NIC finally
I tried to use a tool to crack it.
I searched the internet and finally found a practical articleArticle. After reading this article, I have a general understanding of the entire cracking process. in the past, ADSL users used the PAP protocol or Chap protocol in the PPP protocol for identity authentication. Since the PAP protocol uses plaintext to transmit key information, you only need to establish a pppoe server and use the PAP protocol for identity authentication, when the vro communicates

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
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 basic syntax, basic usage, and packet-filtration rules:1. Filter IP, such as source IP or destination IP equals an IPExample: IP.SRC eq 192.168.1.107 or IP.DST eq 192.168.1.107 or IP.ADDR eq 192.168.1.107//Can both show source IP and destination IPExamples of Wireshark graphics Windows running on Linux, other worry-rule actions are similar, no longer.IP.SRC eq 10.175.168.182Example:Tip: In the fil

0. preface in Firefox and Google browsers, you can easily debug the network (capture HTTP packets), but in the 360 series browsers (compatible mode or standard IE Mode) it is not that convenient to capture HTTP packets. Even though HttpAnalyzer and other jobs can be used, they are all paid software. Wireshark can also capture HTTP requests and responses through proper filtering and operations. The following describes the specific operations. Assume th

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
When using the default settings of Wireshark, you get a lot of redundant information so that it's hard to find the packets you need. Using filters can help us quickly find the packages we need in a very complex and complex result. Filters are divided into two types: Capture filter and display filter.The capture filter is used to determine what information is recorded in the capture results and needs to be set
