Netcat: ( TCP/IP Swiss Army Knife ) | DevOps | Linux | Use-Cases

-

netcat (often abbreviated to nc) is a computer networking utility for reading from and writing to network connections using TCP and UDP

The command  is designed to be a dependable back-end that can be used directly or easily driven by other programs and scripts. At the same time, it is a feature-rich network debugging and investigation tool, since it can produce almost any kind of connection its user could need and has a number of built-in capabilities. 

Features:
  - port scanning, transferring files, and port listening, and it can be used as a backdoor

The way I learn CLI tools is by first learning the usage of the tool, followed by committing a few simple commands to muscle memory

I have tried to cover few use cases with netcat in this video

That being said, I enrolled to complete CKA, and here are a few points which made it easier for me to decide. 1. Cost : For some, this may not be the most important, but I still consider if its worth spending 200/300$ for it...
