Install Nethogs on Ubuntu 20.04

In this tutorial, we will show you how to install Nethogs on Ubuntu 20.04 LTS. For those of you who didn’t know, methods is a small ‘net top’ tool. Instead of breaking the traffic down per protocol or per subnet, as most tools do, it groups bandwidth by process. It is feature-rich, supports both IPv4 and IPv6, and in my opinion, is the best utility when you want to identify programs that are consuming all your bandwidth on your Linux machine.

This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo‘ to the commands to get root privileges. I will show you the step-by-step installation of the Nethogs monitoring network traffic on Ubuntu 20.04 (Focal Fossa). You can follow the same instructions for Ubuntu 18.04, 16.04, and any other Debian-based distribution like Linux Mint.


  • A server running one of the following operating systems: Ubuntu 20.04, 18.04, and any other Debian-based distribution like Linux Mint or elementary OS.
  • It’s recommended that you use a fresh OS install to prevent any potential issues.
  • An active internet connection. You’ll need an internet connection to download the necessary packages and dependencies for Nethogs.
  • A non-root sudo user or access to the root user. We recommend acting as a non-root sudo user, however, as you can harm your system if you’re not careful when acting as the root.
