====== Installing FreeRADIUS on Ubuntu 26.04 ======
===== Introduction =====
  * Install FreeRADIUS and MySQL module.
<code bash>
sudo apt-get -y install libdatetime-perl libdbd-mysql-perl libdigest-hmac-perl libdatetime-format-rfc3339-perl eapoltest
sudo apt-get -y install freeradius freeradius-mysql
# Answer yes to the question to install these packages with their dependencies
# Please note that the installation of this package generates some things that can take a lot of time on slower computers.
</code>
  * Activating and starting FreeRADIUS
<code bash>
sudo systemctl enable freeradius
sudo systemctl start freeradius
sudo systemctl status freeradius
</code>
====== Configure FreeRADIUS ======
  * Proceed as follows to configure FreeRADIUS to work with RADIUSdesk
<code bash>
# Stop the service if it is already running
sudo systemctl stop freeradius
# Backup the original FreeRADIUSdirectory
sudo mv /etc/freeradius /etc/freeradius.orig
# Copy the RADIUSdesk modified FreeRADIUS directory
sudo cp -R /var/www/html/cake4/rd_cake/setup/radius/freeradius /etc
sudo chown -R freerad: /etc/freeradius/3.0/
sudo chown freerad:www-data /etc/freeradius
sudo chown freerad:www-data /etc/freeradius/3.0
sudo chown freerad:www-data /etc/freeradius/3.0/dictionary
sudo  mkdir /var/run/freeradius
sudo chown freerad: /var/run/freeradius
</code>
  * Configure the site-wide shared secret. This is the value used by ALL dynamic clients.
<code bash>
sudo vi /etc/freeradius/3.0/sites-enabled/dynamic-clients
</code>
  * Locate this part of the file and change FreeRADIUS-Client-Secret to the value you want to use.
<code bash>
#  Echo the IP address of the client.
FreeRADIUS-Client-IP-Address = "%{Packet-Src-IP-Address}"
 
# require_message_authenticator
FreeRADIUS-Client-Require-MA = no
 
# secret
FreeRADIUS-Client-Secret = "testing123"
 
# shortname
FreeRADIUS-Client-Shortname = "%{Packet-Src-IP-Address}"
</code>
  * After you have completed these steps, restart FreeRADIUS.
<code bash>
sudo systemctl restart freeradius
sudo systemctl status freeradius
</code>
