In this tutorial we will learn how to install Nethogs on Ubuntu 22.04 LTS opearting system.
Introduction
In today’s interconnected world, efficient network management is essential for individuals and organizations alike. Whether you’re a casual user concerned about bandwidth usage or a network administrator striving to optimize performance, having the right tools at your disposal is crucial. One such tool that stands out in the realm of network monitoring is Nethogs. In this article, we’ll explore what Nethogs is, how it works, and how you can leverage its capabilities to gain better control over your network.
Understanding Nethogs
Nethogs is a command-line utility for Linux systems that provides real-time monitoring of network bandwidth usage by individual processes. It allows users to identify which applications or processes are consuming network resources, helping to pinpoint potential bottlenecks and optimize overall network performance. Nethogs breaks down network usage on a per-process basis, providing valuable insights into the data transfer activities of each running application.
Key Features of Nethogs
- Real-time Monitoring. Nethogs excels in providing instant and continuous updates on network usage, making it a powerful tool for diagnosing network issues in real-time. Users can see which processes are actively using the network and the amount of bandwidth they are consuming.
- Per-Process Breakdown. One of Nethogs’ standout features is its ability to break down network usage on a per-process basis. This granularity allows users to identify specific applications or services responsible for high network traffic, helping to prioritize and optimize resource allocation.
- User-Friendly Interface. While Nethogs operates primarily through the command line, its interface is designed to be user-friendly, displaying information in a clear and easily understandable format. Users can quickly interpret the data presented by Nethogs, making it accessible even for those less familiar with command-line utilities.
How To Install Nethogs on Ubuntu 22.04 LTS
To install Nethogs on Ubuntu, we can use the apt package manager, which is the default package manager for Debian-based Linux distributions like Ubuntu. Here’s a step-by-step guide:
1 .Update Package List
Before installing any new software, it’s a good practice to update the package list to ensure you get the latest version. Run the following command:
$ sudo apt update
2. Install Nethogs
Once the package list is updated, you can proceed to install Nethogs. Use the following command:

We will be prompted to enter your password. After entering the password, press Enter to continue with the installation.
3. Run Nethogs
After the installation is complete, you can run Nethogs by simply typing the following command in the terminal:
$ sudo nethogs
This will start Nethogs and display real-time network usage information for your system.
Optional: If you have multiple network interfaces and want to monitor a specific one, you can specify the interface as follows (replace eth0 with the desired interface name):
$ sudo nethogs eth0
That’s it! We have successfully installed and run Nethogs on your Ubuntu system. You can use the information provided by Nethogs to monitor the network usage of individual processes and identify potential bandwidth hogs on your system.
Conclusion
Nethogs is a valuable tool for anyone looking to gain insights into their network’s behavior and resource usage. Its real-time monitoring capabilities and per-process breakdown make it an essential utility for both individual users and network administrators. By identifying bandwidth-hungry applications, users can take proactive measures to optimize their network, ensuring a smoother and more efficient online experience. Incorporating Nethogs into your network management toolkit can lead to better resource utilization, improved performance, and a more responsive and reliable network infrastructure.
