For some of the examples we are going to use tcpdump to capture what's going on the network so we can see the traffic generated by scapy.
When running tcpdump it will display a banner like this, we'll disregard this in the following ouput files.
tcpdump: verbose output suppressed, use -v or -vv for full protocol decode listening on lo, link-type EN10MB (Ethernet), capture size 262144 bytes
