Description

Coding PING from scratch in C

Ping is a tool which sends a data packet to a device on the local network or on the internet. When the remote node receives this packet, it responds in kind. As soon as the first device receives this response, it knows that the connection works.

This is a very useful troubleshooting tool that ships with every major operating system, but today we are going to code our own. And we will do it using raw sockets, capturing every packet on the network and filtering out all but ping. Basically we will communicate directly with the network card of the computer, and design the IP packet by hand.


-Why learn C from dr Jonas Birch and not from the other ten Udemy instructors?

Experience in the C language. When dr Birch was 18 years old and had been coding C for five years, he was traveling all over Europe, invited to different coding and security conferences, giving lectures about C and security. Since then he has coded C almost every day - for an additional 20 years!

Experience in teaching. Dr Birch has been teaching the C language (live) almost full time the last six years, helping hundreds and hundreds of students learn the mother of all languages - in Linux.

Very soothening voice and amazing sound quality. Dr Birch has a very dark, relaxing voice which is very easy to listen to (a really underestimated feature). He is recording in a professional recording studio with enterprise level microphone and equipment, which makes for a very good listening experience.
