The Linux test tool tcpdump command is used to monitor TCP/IP connections and directly read data headers at the data link layer. You can specify which data packets are monitored and which control formats are to be displayed. For example, we want to monitor the communication between all Ethernet and execute the following command: tcpdump-ieth0, let's take a look at the specific content. Even in a relatively
