RADIUS, which stands for “Remote Authentication Dial In User Service”, is a network protocol -- a system that defines rules and conventions for communication between network devices -- for remote user authentication and accounting. Commonly used by Internet Service Providers (ISPs), cellular network providers, and corporate and educational networks, the RADIUS protocol serves three primary functions:

• Authenticates users or devices before allowing them access to a network

• Authorizes those users or devices for specific network services

• Accounts for and tracks the usage of those services

Freeradius Features

• An open and scalable solution

• Broad support by a large vendor base

• Easy modification

• Separation of security and communication processes

• Adaptable to most security systems

• Workable with any communication device that supports RADIUS client protocol

daloRADIUS is an advanced RADIUS web platform aimed at managing Hotspots and general-purpose ISP deployments. It features rich user management, graphical reporting, accounting, and integrates with GoogleMaps for geo-locating (GIS). daloRADIUS is written in PHP and JavaScript and utilizes a database abstraction layer which means that it supports many database systems, among them the popular MySQL, PostgreSQL, Sqlite, MsSQL, and many others.

It is based on a FreeRADIUS deployment with a database server serving as the backend. Among other features it implements ACLs, GoogleMaps integration for locating hotspots/access points visually and many more features. daloRADIUS is essentially a web application to manage a radius server so theoretically it can manage any radius server but specifically it manages FreeRADIUS and it's database structure. Since version 0.9-3 daloRADIUS has introduced an application-wide database abstraction layer based on PHP's PEAR::DB package which support a range of database servers.

Before Installing make sure you have Ubuntu 16.04 LAMP server installed and ready for freeradius.

Preparing your system

Open the terminal and run the following command

sudo apt-get install php-common php-gd php-curl php-mail php-mail-mime php-pear php-db php-mysql

Install freeradius using the following command

sudo apt-get install freeradius freeradius-mysql freeradius-utils

Create Freeradius Database

You can use the following command to create freeradius database

sudo mysql -u root -p

Enter password:

mysql> create database radius;

mysql> grant all on radius.* to radius@localhost identified by "password";

Query OK, 0 rows affected (0.00 sec)

Insert the freeradius database scheme using the following commands

sudo mysql -u root -p radius < /etc/freeradius/sql/mysql/schema.sql

Enter password:

sudo mysql -u root -p radius < /etc/freeradius/sql/mysql/nas.sql

Enter password:

Create new user for radius database

sudo mysql -u root -p

mysql> use radius;

Reading table information for completion of table and column names

You can turn off this feature to get a quicker startup with -A

Database changed

mysql> INSERT INTO radcheck (UserName, Attribute, Value) VALUES (‘sqltest', ‘Password', ‘testpwd');

Query OK, 1 row affected (0.04 sec)

mysql> exit

Bye

Freeradius Configuration

You need to edit /etc/freeradius/sql.conf file

sudo vi /etc/freeradius/sql.conf

Make sure you have the following details

database = mysql
login = radius
password = password

Uncomment the following

readclients = yes

Save and Exit the file

Now you need to edit the /etc/freeradius/sites-enabled/default file

sudo vi /etc/freeradius/sites-enabled/default

Uncomment the sql option in the following sections

accounting

# See “Authorization Queries” in sql.conf

sql

session

# See “Authorization Queries” in sql.conf

sql

Post-Auth-Type

# See “Authorization Queries” in sql.conf

sql

Save and Exit the file

Now edit /etc/freeradius/radiusd.conf file

sudo vi /etc/freeradius/radiusd.conf

#Uncomment the following option

$INCLUDE sql.conf

Save and exit the file

Now you can stop the free radius server using the following command

sudo /etc/init.d/freeradius stop

Run freeradius in debugging mode. If there is no error, you are ready to go.

sudo freeradius -X

Start the freeradius using the following command

sudo /etc/init.d/freeradius start

Test the radius server using the following command

sudo radtest sqltest testpwd localhost 18128 testing123

Ouput as follows

Sending Access-Request of id 68 to 127.0.0.1 port 1812
User-Name = "sqltest"
User-Password = "testpwd"
NAS-IP-Address = 127.0.1.1
NAS-Port = 18128
Message-Authenticator = 0x00000000000000000000000000000000
rad_recv: Access-Accept packet from host 127.0.0.1 port 1812, id=68, length=20

Daloradius Installation

You can download the Daloradius latest version from here

Once you downloaded the daloradius-0.9-9.tar.gz file you need to extract using the following command

$ tar xvfz daloradius-0.9-9.tar.gz

$ mv daloradius-0.9-9 daloradius

$ mv daloradius /var/www/html

Change Permissions

sudo chown www-data:www-data /var/www/html/daloradius -R

sudo chmod 644 /var/www/html/daloradius/library/daloradius.conf.php

Mysql database need to setup for daloradius.We need to do is to import the daloradius scheme into our existing radius database.

$ cd /var/www/html/daloradius/contrib/db

sudo mysql -u root -p radius < mysql-daloradius.sql
configure the following daloradius setting.

sudo vi /var/www/html/daloradius/library/daloradius.conf.php

Change the database password

$configValues[‘CONFIG_DB_PASS'] = ‘password';

Save and exit the file

Now you need to configure daloradius website under /etc/apache2/sites-available

sudo vi /etc/apache2/sites-available/daloradius.conf

add the following lines

Alias /daloradius "/var/www/html/daloradius/"

<Directory /var/www/html/daloradius/>
Options None
Order allow,deny
allow from all
</Directory>

Save and exit the file

Enable daloradius website using the following command

sudo a2ensite daloradius

Enabling site daloradius.

To activate the new configuration, you need to run:

sudo service apache2 reload

Daloradius Web GUI

you can access daloradius GUI using http://server-ip/daloradius and the login screen as follows

Use the following login details

username: administrator
password: radius

If you are running PHP 7 then you might see the following error

Database connection error
Error Message: DB Error: extension not found

To fix the above error you need to do the following changes Credit goes here

Changing file library/daloradius.conf.php

It's required to update daloRADIUS's database connection code so that it identifies the MySQL server using the new and improved mysqli driver:

Open for editing the file library/daloradius.conf.php and locate the configuration variable CONFIG_DB_ENGINE and change it to the value of mysqli (it is now probably set to mysql, notice the extra i). It should end up looking as follows: $configValues[‘CONFIG_DB_ENGINE'] = ‘mysqli';
Changing file library/opendb.php

Open for editing the file library/opendb.php

At the very end of the file just add this new line of code: $dbSocket->query("SET GLOBAL sql_mode = ";"); which makes the MySQL version work with less strict SQL syntax

Once you logged in you should see similar to the following screen
