====Installing the server====
----
Firstly, update the package list and upgrade to the latest packages:
Firstly, update the package list and upgrade to the latest packages:
sudo apt update
sudo apt update
sudo apt upgrade
sudo apt upgrade
</pre>
Next, install freeradius package:
<pre>
sudo apt install freeradius
</pre>
====Defining a Client====
----
Client - Hotspot that will use freeradius to authenticate users.
In order to add/edit clients, we need to access clients.conf file, use your favourite text editor to access it:
<pre>
sudo nano /etc/freeradius/3.0/clients.conf
</pre>
For this example we will add the following lines in order to accept any IP address as a client:
<pre>
client 0.0.0.0/0 {
secret = demosecret
shortname = 0.0.0.0/0
}
</pre>
Note: IP of a specific Public IP of the client can be used instead of 0.0.0.0/0
====Defining a User and Password====
----
Before we create a user and password, let's use MD5 encryption instead of a clear text password. We will generate MD5 for '''demo123''' password using the following command:
<pre>
echo -n demo123| md5sum | awk '{print $1}'
</pre>
We will now define credentials for user '''demo'''. Use your favourite text editor to open '''users''' file:
<pre>
sudo nano /etc/freeradius/3.0/users
</pre>
Add required lines to the file:
<pre>
demo MD5-Password:= "62cc2d8b4bf2d8728120d052163a77df"
Reply-Message := "%{User-Name} authenticated successfully"
</pre>
</pre>
