Radius Server

=Installing FreeRadius= Installing freeradius in Ubuntu 16.10:

Source: blog.moatazthenervous.com sudo apt-get install freeradius

Configuration
Edit the freeradius users: sudo nano /etc/freeradius/3.0/users

Uncomment the user 'John Doe': "John Doe" Auth-Type := Local, User-Password == "hello" Reply-Message = "Hello, %u"

Add a new User with Group Name: aman           Cleartext-Password := "pwd123" Citrix-User-Groups = "S_UA_G_Superuser", Reply-Message = "Hello, %{User-Name}"

Test the connectivity from local machine: sudo radtest "John Doe" hello 127.0.0.1 0 testing123

Remote access to the radius server sudo nano /etc/freeradius/clients.conf

And add the following snippet:

client 0.0.0.0/0 { secret = "mysecret" shortname = name }

Now from another machine, try the following: radtest "John Doe" "hello" 10.10.40.1 0 "mysecret"

You will get Access-Accept packet and "Hello, John Doe" messages.

Logging
Source: wiki.freeradius.org The "log" section of the radiusd.conf file is where the primary logging configuration for the FreeRADIUS server is located. log { destination = files file = ${logdir}/radius.log    # If Server is running in debugging mode, this file is NOT used. syslog_facility = daemon stripped_names = no   auth = no    auth_badpass = no    auth_goodpass = no }
 * 1)   requests = ${logdir}/radiusd-%{%{Virtual-Server}:-DEFAULT}-%Y%m%d.log
 * 1)   msg_goodpass = ""
 * 2)   msg_badpass = ""

Destination options: files - log to "file", as defined below. syslog - send log messages to syslog stdout - log to standard output. stderr - log to standard error.

Installation
Prerequisites: sudo apt-get install php5-common php5-gd php-pear php-db libapache2-mod-php5 php-mail

Freeradius Installation: sudo apt-get install freeradius freeradius-mysql freeradius-utils

Database
Create Freeradius Database sudo mysql -u root -p

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

Insert the freeradius database scheme: sudo mysql -u root -p radius < /etc/freeradius/sql/mysql/schema.sql sudo mysql -u root -p radius < /etc/freeradius/sql/mysql/nas.sql

Create new user for radius database sudo mysql -u root -p mysql> use radius; mysql> INSERT INTO radcheck (UserName, Attribute, Value) VALUES (‘sqltest', ‘Password', ‘testpwd'); mysql> exit

Freeradius
You need to edit /etc/freeradius/sql.conf file sudo nano /etc/freeradius/sql.conf

Make sure you have the following details database = mysql login = radius password = password

Uncomment the following readclients = yes

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


 * 1) See “Authorization Queries” in sql.conf

sql

session


 * 1) See “Authorization Queries” in sql.conf

sql

Post-Auth-Type


 * 1) See “Authorization Queries” in sql.conf

sql

Now edit /etc/freeradius/radiusd.conf file sudo nano /etc/freeradius/radiusd.conf

Uncomment the following option $INCLUDE sql.conf

Restart freeradius server: 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

Output 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
Download the Daloradius latest version: wget https://downloads.sourceforge.net/project/daloradius/daloradius/daloradius0.9-9/daloradius-0.9-9.tar.gz tar xvfz daloradius-0.9-9.tar.gz mv daloradius-0.9-9 daloradius mv daloradius /var/www

Change Permissions sudo chown www-data:www-data /var/www/daloradius -R sudo chmod 644 /var/www/daloradius/library/daloradius.conf.php

Mysql database need to setup for daloradius by importing the daloradius scheme into 'radius' database.

cd /var/www/daloradius/contrib/db

sudo mysql -u root -p radius < mysql-daloradius.sql

Configure the following daloradius setting: sudo nano /var/www/daloradius/library/daloradius.conf.php

Change the database password $configValues['CONFIG_DB_PASS'] = 'password';

Now you need to configure daloradius website under sudo nano /etc/apache2/sites-available/daloradius.conf

add the following lines Alias /daloradius "/var/www/daloradius/"

 Options None Order allow,deny allow from all 

Enable and Activate daloradius website using the following command sudo a2ensite daloradius sudo service apache2 reload

Daloradius Web GUI http://10.107.88.93/daloradius

Use the following login details username: administrator password: radius

Troubleshooting Daloradius
aman@ubuntu:~$ mysql -u root -ppwd@123 radius < /etc/freeradius/sql/mysql/schema.sql -bash: /etc/freeradius/sql/mysql/schema.sql: Permission denied
 * If you get permission denied error when importing schema:

Copy the files to home dir & change the file owner: sudo cp /etc/freeradius/sql/mysql/schema.sql ~ sudo cp /etc/freeradius/sql/mysql/nas.sql ~ sudo chown aman:aman ~/*.sql

 * If the page stops loading after login, and you get similar errors in apache error logs:

Check if all the dependencies are installed or not: php -m

If DB is missing, install it:

sudo pear install DB

So we have to change the rules for syntax reading:
 * If above issue still persists, then the Problem is, i had PHP7.0 installed, but daloradius is only supported until 5.0

Make Sure you got all necessary packages

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

Change Syntax: cd /var/www/html/daloradius/library/ vim daloradius.conf.php -> CONFIG_DB_ENGINE auf "mysqli"        # from mysql to mysqli vim opendb.php -> $dbSocket->query("SET GLOBAL sql_mode = '';"); #append this line at the end of the file

Now we have to give the db-user freeradius super rights with: mysql -u root -p mysql> GRANT SUPER ON *.* TO 'freeradius'@'localhost' IDENTIFIED BY 'password'; mysql> flush privileges;

You might have to import a mysql schema with: cd /var/www/html/daloradius/contrib/db/ mysql -u root -p radius <mysql-daloradius.sql

sudo nano /var/www/daloradius/library/daloradius.conf.php
 * If you get DB connection failed error:

$configValues['CONFIG_DB_USER'] = 'root'; $configValues['CONFIG_DB_PASS'] = 'ppwd@123';

Saving the file will allow you in the Landing page.

rad_recv: Access-Reject packet from host 127.0.0.1 port 1812
 * If you happen to run into this issue

Then edit the below file: sudo nano /etc/freeradius/sites-available/default

~ line 177 and uncomment sql sql
 * 1) Look in an SQL database. The schema of the database
 * 2) is meant to mirror the “users” file.
 * 3) See “Authorization Queries” in sql.conf
 * 1) See “Authorization Queries” in sql.conf

If you are unable to use radtest from other servers, check credentials for 0.0.0.0/0 in below file: sudo nano clients.conf

Debugging
sudo service freeradius stop sudo freeradius -X
