Installing Wireshark on Ubuntu 22.04

Wireshark is a popular free and open-source packet analyzer used for network troubleshooting, analysis, software and protocol development, and education. It allows users to capture and view the network traffic on their computer.

Step 1: Update the System

Before installing Wireshark, it's recommended to update the system's package manager repositories to ensure that the latest software versions are available:

sudo apt update
sudo apt upgrade

Step 2: Install Wireshark

Wireshark can be installed from the default Ubuntu repositories. Open the terminal and run the following command:

sudo apt install wireshark

During the installation process, you will be prompted to choose whether non-superusers should be able to capture packets. Select 'Yes' to allow this.

Step 3: Configuring Wireshark

By default, Wireshark needs special permissions to capture network traffic. To allow non-superusers to run Wireshark without sudo, it's necessary to add the user to the 'wireshark' group:

sudo usermod -aG wireshark $USER
sudo reboot

After the system reboots, you should be able to run Wireshark as a non-superuser.

Step 4: Running Wireshark

You can launch Wireshark from the application menu or by running the following command in the terminal:

wireshark

Upon launching Wireshark, select the network interface you want to capture packets from. You can start capturing traffic by clicking on the 'Start' button.

Note: Capturing network traffic may require administrative privileges.

Congratulations! You have successfully installed Wireshark on Ubuntu 22.04. Happy network analyzing!
