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

Abstract: This article briefly introduces TCP connection-oriented theory, describes the meaning of each field of TCP packets in detail, and selects TCP connections from the wireshark capture group to establish relevant packet segments for analysis. I. Overview TCP is a reliable connection-oriented transmission protocol. Two processes need to establish a connection before sending data to each other. The connection here is only some cache and status va
