Скачать или смотреть I created an IP tunnel from scratch using Linux TUN device and C!

Hi everyone,
In this video I will be discussing about network tunnels, what are they, how they work and then to understand it better I will create a IP tunnel from scratch in C using just Linux TUN device.
Linux TUN device allow us to create network interfaces which operate at user space and instead of sending packets to the wire, they write packets to a file descriptor which is pretty cool. I will be explaining how to use TUN device and how they can help us to create a virtual network between two nodes.

Hope you all will enjoy this video and do let me know in the comments what kind of tunnels you have used and how have you created them!
