Notes to self from an excellent resource:

tcpdump command is also called as packet analyzer.
tcpdump allows us to save the packets that are captured, so that we can use it for future analysis. The saved file can be viewed by the same tcpdump command. We can also use open source software like wireshark to read the tcpdump pcap files.
