How to Install Wireshark on CentOS 6.2

Wireshark is a powerful and widely used network protocol analyzer that allows you to capture and analyze network traffic. It is an essential tool for network administrators and security professionals.

In this guide, we will walk you through the steps to install Wireshark on CentOS 6.2.

Step 1: Enable EPEL Repository:

Wireshark is not available in the default CentOS 6.2 repositories. To install it, we need to enable the Extra Packages for Enterprise Linux (EPEL) repository. Open your terminal or SSH into your server and execute the following command:

sudo yum install epel-release

This command installs the EPEL repository, which provides additional packages not found in the default CentOS repositories.

Step 2: Install Wireshark:

Once the EPEL repository is enabled, you can proceed to install Wireshark. Run the following command:

sudo yum install wireshark

This command will download and install Wireshark and its dependencies from the EPEL repository.

Complete!

Step 3: Configure Wireshark (Optional):

By default, Wireshark can only be run by the root user. If you want to allow non-root users to use Wireshark, you need to grant them permission. Execute the following command:

sudo groupadd wireshark
sudo usermod -a -G wireshark your_username
sudo chgrp wireshark /usr/sbin/dumpcap
sudo chmod 750 /usr/sbin/dumpcap
sudo setcap cap_net_raw,cap_net_admin=eip /usr/sbin/dumpcap

Replace ‘your_username’ with the actual username of the non-root user. These commands create a group called ‘wireshark’, add the user to the group, and set the necessary permissions and capabilities.

Step 4: Start Wireshark:

After installation and configuration, you can start Wireshark by running the following command:

wireshark

This command launches the Wireshark graphical user interface (GUI), where you can start capturing and analyzing network traffic.

Conclusion:

In this guide, we have learned how to install Wireshark on CentOS 6.2. By following these steps, you can have Wireshark up and running on your system, allowing you to analyze network traffic and troubleshoot network issues. Remember to use Wireshark responsibly and in accordance with applicable laws and regulations.
