The netstat command provides a tremendous amount on information on network activity. With the -s option (netstat -s), it will display summaries for various protocols such as packets received, active connections, failed connections and a lot more.

In this post, we’re going to look at various portions of the netstat -s command’s output using crafted aliases to make it easier.
