I created a network packet sniffer from scratch in C using only raw sockets!

In this video I will be discussing about Raw sockets in Linux which is a type of network socket. In order to understand how they work and how to use them I will be building a network packet sniffer from scratch in C using only raw socket (packet socket to be specific) without using any external libraries like libpcap. This should help as appreciate some of the strong utilities and benefits provided by raw sockets.

Hope you will enjoy this video and let me know in comments if you have used raw/packet sockets before and how you have used them.
