How do you analyze a pcap file?
To capture PCAP files you need to use a packet sniffer. A packet sniffer captures packets and presents them in a way that’s easy to understand. When using a PCAP sniffer the first thing you need to do is identify what interface you want to sniff on. If you’re on a Linux device these could be eth0 or wlan0.
