Netstat Command in Linux | How to Use Netstat Command in Linux | Network Statistics in Linux
In this video, you'll learn how to use the netstat command in Linux to monitor and troubleshoot network connections, routing tables, listening ports, interface statistics, and network protocols. Netstat (Network Statistics) is a powerful networking utility that helps Linux administrators, DevOps engineers, SREs, and cybersecurity professionals analyze network activity and diagnose connectivity issues.
We will cover how to view active TCP/UDP connections, identify listening services, display routing information, check interface statistics, find processes using specific ports, and understand the most commonly used netstat options. You'll also learn when to use modern alternatives such as the ss command.
