OverviewTCP is a reliable connection-oriented transport protocol, two processes to send data before the need

When processing TCP data, we need to consider a problem of sticking packets. The so-called sticking packet is that the data received this time is not necessarily completely corresponding to the data sent by the other party. the data sent by the other Party may need to be received multiple times before it can be completed. The actual situation should be reviewed. To solve the packet ordering problem, a data analysis protocol must be developed for proce

Based on the previous security protocol analysis of the SSL protocol, first review the content of the SSL protocol and then use Wireshark to grasp the contents of the specific flow of packets. The SSL protocol stack is located between the TCP and the application layer, and i

After the installation is successful, you can view this certificate information:third, crawl the sample app packetIn this way, our device will have the Fiddler c

Wireshark packet capture analysis-network protocol Wireshark is currently the most popular packet capture tool. It can run in windows, Linux, and Mac OS X operating systems, and provides a friendly graphical interface. Wireshark also provides a powerful data packet capture function. It can capture the network data pack

The routing protocol analyzer is divided into three types: Portable routing protocol analyzer based on notebook + data collection box, handheld integrated routing protocol analyzer, and distributed routing

filteringThe use of filtering is very important, when beginners use Wireshark, will get a lot of redundant information, in thousands of or even tens of thousands of records, so that it is difficult to find the part of their own. Filters help us quickly find the information we need in a large amount of data.There are two types of filters:One is the display filter, which is the one on the main interface, which is used to find the required records in th

For large networks, faults may be difficult to handle, so an effective performance and function testing tool is very convenient. In order to adapt to the current wireless network, the new generation of Wi-Fi wireless protocol analyzer brings new vigor to the network test. The transmission media of WLAN is electromagnetic waves, which are almost ubiquitous and have no obvious boundaries. However, almost all

With the development of wireless LAN technology, protocol analyzer technology is not far behind, So how should we install, operate and protect it? Here we will introduce it to you. The transmission media of WLAN is electromagnetic waves, which are almost ubiquitous and have no obvious boundaries. However, almost all Wi-Fi hardware has certain security vulnerabilities. Some simplified client configurations m

The routing protocol analyzer is still very important in routing applications, and the technology is gradually improved. The best way to analyze data packets transmitted over the network is largely determined by the device you have at hand. In the early stages of network technology development using the Internet era of HUB or HUB), the answer is simple. You only need to insert the line on a HUB, and everyth

1. General analysisWhen Wireshark is started, all parsers are initialized and registered. The information to be registered includes the protocol name, the information for each field, the keyword to filter, the underlying protocol and port to associate with (handoff), and so on. In the parsing process, each parser is responsible for parsing its own

We can use the network protocol analyzer to observe the network protocol analysis. Here we will explain the network analyzer. The best way to analyze data packets transmitted over the network depends largely on the device you have. in the early stages of network technology development using the Internet era of HUB or H
