4 Essential Linux Networking Commands (No Extra Tools)

Are you inside a container or stripped-down Linux system and missing tools like netcat, dig, nmap, netstat, or even ip?
Don’t worry — you can still troubleshoot networking issues with **built-in commands** that require **no extra packages**.

In this video, you’ll learn **4 essential Linux networking commands** that work even in minimal environments — perfect for containers, microVMs, and secure production images.

🚀 What you'll learn:

* How to test open TCP ports without netcat, nmap, or telnet
* How to check your IP address without ip or ifconfig
* How to resolve domains without dig or host
* How to view TCP connections without netstat, ss, or lsof

💡 These commands use /dev/tcp, getent, /proc/net/tcp, and hostname -I — available in most Linux distros by default.
