How to wireshark linux install

Step 1: Update Your System

Before installing any new software, it’s a good practice to update your system’s package list and ensure your system is up to date. Run the following commands:

sudo apt update && sudo apt upgrade -y

This will update the package lists for your repositories and install any pending updates to your system.

Step 2: Install Wireshark on Ubuntu/Debian-based Systems

For Ubuntu and other Debian-based distributions, Wireshark is available directly from the official repositories. To install it, use the following command:

sudo apt install wireshark

During installation, you’ll be asked if non-superusers should be allowed to capture packets. Choose “Yes” if you want users in the “wireshark” group to be able to capture network packets.

Once installed, you can start Wireshark by running the following command:

wireshark

Step 3: Install Wireshark on Fedora

On Fedora, Wireshark can be installed through the default package manager dnf. Run the following command:

sudo dnf install wireshark

Once installed, start Wireshark by typing:

wireshark

Step 4: Install Wireshark on Arch Linux

For Arch Linux and Manjaro users, Wireshark is available in the Arch User Repository (AUR). You can install it using pacman:

sudo pacman -S wireshark-gtk

For users of Arch-based distributions, the GUI version of Wireshark is available under the “wireshark-gtk” package.

If you’re using the newer Qt-based version of Wireshark, you can install it with:

sudo pacman -S wireshark-qt

Once installed, launch Wireshark by running:

wireshark

Step 5: Configure Permissions (Optional)

If you wish to capture packets without root privileges, you need to add your user to the wireshark group. To do so, run the following command:

sudo usermod -aG wireshark $USER

After running this command, log out and log back in for the group changes to take effect. This will allow non-root users to capture network traffic using Wireshark.

Step 6: Start Wireshark

Once installed, you can start Wireshark by searching for it in your application menu or typing the following command in the terminal:

wireshark

The Wireshark interface should open, allowing you to begin capturing and analyzing network traffic on your system.

Step 7: Wireshark GUI Features

Wireshark provides an easy-to-use graphical interface with many powerful features, including:

• Packet Capture: Wireshark can capture network traffic from your system’s network interfaces (Ethernet, Wi-Fi, etc.).
• Protocol Analysis: Wireshark can decode hundreds of protocols and display them in a human-readable format.
• Filter Options: Use filters to display specific types of traffic, such as HTTP requests, DNS queries, or TCP connections.
• Export and Save Data: You can export captured data to different formats for further analysis or sharing.

Step 8: Troubleshooting

If you encounter any issues during installation or usage, consider the following tips:

• Missing Wireshark Package: Ensure that you have the necessary repositories enabled (e.g., EPEL for Fedora).
• No Permission to Capture Packets: Ensure that your user is added to the “wireshark” group and that you’ve logged out and back in.
• Wireshark Not Starting: Try launching Wireshark from the terminal to check for error messages that can help troubleshoot the issue.
