Recently, when learning the NIC driver, we need to capture the situations where the Nic sends and receives data. so we found the tcpdump and wireshark tools, which are used to capture data, wireshark is used to analyze the captured data. the usage is recorded below: Tcpdump usage method (1) first, key words about the type mainly include host, net recently, when learning the NIC driver, you need to capture t

Summary: This paper introduces the knowledge of TCP-oriented connection theory, and describes the meanings of each field of TCP message. In this paper, a TCP connection is selected from the Wireshark capture packet to establish the relevant message segment.I.

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 HUB), the answer is very simple. You only need to insert the line on a HUB, and everything
