Installing FreeRADIUS on NetBSD

In this tutorial, we will go through the steps to install FreeRADIUS on NetBSD.

Prerequisites

  • A NetBSD machine with root access
  • Internet connection

Step 1: Update the package repository

First, we need to update the package repository by running the following command:

pkgin update

This will ensure that we have the latest packages available.

Step 2: Install FreeRADIUS

To install FreeRADIUS, run the following command:

pkgin install freeradius

This will install FreeRADIUS and all its dependencies.

Step 3: Configure FreeRADIUS

Now that FreeRADIUS is installed, we need to configure it for our environment. The configuration files are located in the /usr/pkg/etc/raddb directory.

We can start by editing the main configuration file /usr/pkg/etc/raddb/radiusd.conf to suit our needs. This file contains the basic configuration settings for FreeRADIUS.

Next, we need to configure the clients that will be connecting to our RADIUS server. This can be done in the /usr/pkg/etc/raddb/clients.conf file.

We also need to create user accounts that can authenticate against our RADIUS server. This can be done in the /usr/pkg/etc/raddb/users file.

Step 4: Start the FreeRADIUS service

To start the FreeRADIUS service, run the following command:

/usr/pkg/sbin/radiusd -f

This will start the FreeRADIUS server in the foreground. If you want to start the server in the background, use the -d option instead.

Step 6: Test the FreeRADIUS server

To test if FreeRADIUS is working correctly, you can use the radtest command. This command can be used to simulate a RADIUS authentication request.

Run the following command from the terminal:

radtest <username> <password> <localhost> 0 <shared_secret>

Replace <username> and <password> with the credentials of a user account created earlier. Replace <localhost> with the IP address or hostname of the RADIUS server. Replace <shared_secret> with the secret key configured in the clients.conf file.

If everything is configured correctly, you should receive a "Access-Accept" response from FreeRADIUS.

Conclusion

Congratulations! You have now successfully installed and configured FreeRADIUS on NetBSD. You should now be able to use this RADIUS server to authenticate users and devices on your network.
