Low Level Networking 101: Python Network Sniffer
Description
This video will improve your knowledge about low level networking by teaching you how to create a simple network sniffer in python.
NOTE: Packet sniffing libraries/frameworks like "scapy" is out of scope of this video as we want to focus on the fundamentals. It can be covered on a separate video.
Be sure to use the tools, techniques, or any learnings you in ethical purposes only.
