Running PortScan for week 2 of the course doesn't work

Hey, can you provide a packet capture from trying it and it not working? It looks like you got a non-TCP packet in response. I can add some error-handling code to that, but I'd be interested in seeing what you received that caused the issue.

IP and TCP are undefined nor imported in Part 2.1 PortScan.py
Quick fix has a long list of suggestions but which one should be picked?
