In a previous post I have talked about introduction and basic usage with iptables. I did some more research on the subject and I found out more information about it which I would like to share with you.

Iptables is a powerful and versatile firewall tool that is used to protect and secure networks. It is an open-source program that is installed on Linux-based operating systems. Iptables works by inspecting and filtering network traffic based on a set of rules. These rules define what traffic is allowed and what is blocked, based on criteria such as the source and destination IP address, port number, and protocol.

While learning to program in C++, have this though ever cross your mind that how to exclude all the binary file created with 'make source'? This has happened with me. And that is the reason which inspired me to write this post.
