How to Install Wireshark on Debian 11

Over time, the analysis of a network becomes a very laborious and delicate task. Thanks to tools like Wireshark, we can make the process a little easier. In this post, you will learn how to install Wireshark on Debian 11.

What is Wireshark and what does it do?

According to the tool’s official website:

Wireshark is the world’s largest and most widely used network protocol analyzer. It allows you to see what is going on in your network at a microscopic level and is the de facto (and often de jure) standard in many commercial and non-profit companies, government agencies and educational institutions.

It is free software that allows you to analyze network traffic in real time, and is considered to be the best tool for troubleshooting network problems such as latency or malicious activity such as hacking attempts.

How does Wireshark do this? Well, in a nutshell, it intercepts traffic and converts it into a human-readable format. It also allows you to use search tools, including regular expressions and color highlighting. With this, you can find what you are looking for.

Wireshark has versions for Windows, macOS, Linux, FreeBSD, NetBSD and OpenBSD, so you can install it on almost any computer.
