Wireshark is a premier tool for network analysis, widely utilized for its ability to capture and dissect network traffic in real-time. It is essential for diagnosing network issues, performing security audits, and gaining insights into network protocols. Whether you’re managing a complex enterprise network or learning about network communications, Wireshark offers the versatility and depth needed to analyze packets down to the smallest details.
To install Wireshark on Fedora 40 or 39, you can use the DNF package manager through Fedora’s AppStream. This approach ensures that you get a stable, up-to-date version of Wireshark that integrates smoothly with your Fedora system. This guide will show you how to set up Wireshark on your system, enabling you to effectively monitor and troubleshoot network traffic.

usermod -a -G wireshark _your_username_For example, if your username is ‘joshua’:
usermod -a -G wireshark joshuaAfter completing this step, log back into your regular account:
su <account name>For example:
su joshuaAn alternative way is just using the following command.
sudo usermod -a -G wireshark _your_username_Alternatively, you can add your username to the Wireshark group using a single command:
