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 packets required by users in various ways. However, users often cannot directly obtain the required data from the data packets. This is because all information is encapsulated according to various network protocols during transmission. To capture useful information from massive data packets, you must understand various common network protocols. In order to facilitate the analysis of data packets, this book provides a detailed description of common network protocols, such as ARP, IP, TCP, UDP, ICMP, DHCP, DNS, HTTP, https, FTP, SMTP, POP3, etc.
