Output would be something like below, tcpdump: verbose output suppressed, use -v or -vv for full protocol decode Let’s assume, i want to capture packets from interface “enp0s3” ~]# tcpdump -i enp0s3
When we run the tcpdump command without any options, it will capture packets on the all interfaces, so to capture the packets from a specific interface use the option ‘ -i‘ followed by the interface name. In this tutorial we will discuss how to capture and analyze packets using different practical examples, Example:1) Capturing packets from a specific interface So to stop or cancel the tcpdump command, type “ ctrl+c”.
When we run the tcpdump command without any options then it will capture packets of all the interfaces.
