Linux Grab Command

You can use the following command to grab a package command on a Linux system

8080 192.168. 9.45 -w ./filename.cap

Description

1. Eth0 to monitor the name of the network card, you can use ifconfig to view;
2. TCP represents a packet that crawls only the TCP protocol;
3. Port 8080 is a packet that fetches only 8080 ports;
4. Host 192.168.9.45 represents the packet that only fetches this IP;
5. -W./filename.cap indicates that the fetch results are written to the file, and the file name is Filename.cap;

I generally only use these options, specifically to check the use of the tcpdump command.

The captured package can be viewed using Wireshark.
