How to Install FreeRADIUS on Manjaro

In this tutorial, we will go through the steps to install FreeRADIUS on Manjaro, a popular Arch Linux distribution. FreeRADIUS is a high-performance, open-source RADIUS server that provides authentication, authorization, and accounting services.

Prerequisites

Before we begin, ensure that your Manjaro system is up to date by running the following command:

sudo pacman -Syu

You would also need to have root or sudo access to execute the necessary commands.

Step 1: Install FreeRADIUS

To install FreeRADIUS, you can use the pacman package manager by executing the following command:

sudo pacman -S freeradius

This command will download and install FreeRADIUS along with its dependencies.

Step 2: Configure FreeRADIUS

After installation, the next step is to configure FreeRADIUS. The configuration files are stored in the /etc/freeradius/ directory.

There are numerous ways to configure FreeRADIUS, but we will focus on a basic configuration to get you started. Open the file /etc/freeradius/clients.conf and add the following code:

client my_client {
        ipaddr = 192.168.1.100   # replace with your client IP address
        secret = mysecret        # replace with your client secret
}

This code defines a client that can connect to the FreeRADIUS server with the IP address 192.168.1.100 and the shared secret 'mysecret.' You can add multiple clients by adding similar lines of code with different IP addresses and secrets.

Step 3: Start FreeRADIUS

After configuring FreeRADIUS, the next step is to start the service. You can do this by running the following command:

sudo systemctl start freeradius

This command will start FreeRADIUS and allow clients to connect.

Step 4: Verify FreeRADIUS Installation

To ensure that FreeRADIUS is functioning correctly, you can verify its status by running the following command:

sudo systemctl status freeradius

If FreeRADIUS is running, it will display a message that indicates that the service is active. You can also test FreeRADIUS by connecting a client that is authorized to use the service.

Congratulations! You have successfully installed and configured FreeRADIUS on Manjaro.

Conclusion

FreeRADIUS is a powerful and versatile RADIUS server that provides authentication, authorization, and accounting services. By following the steps in this tutorial, you can set up and configure FreeRADIUS on Manjaro with ease. With a little practice, you can expand its functionality and enhance its performance to meet the needs of your organization.
