When should you use netstat command?

The netstat command is a powerful network utility used in Linux to display network connections, routing tables, interface statistics, masquerade connections, and multicast membership. It is particularly useful in various scenarios:

To monitor active connections and ports in real-time.
To troubleshoot network issues by checking open ports and established connections.
To gather statistics about network interfaces and their performance.
To find which processes are using specific ports.

By running netstat, you can gain insights into your system's network activity and help diagnose any networking problems.
