Free Radius setup/configuration in Linux [Ubuntu/CentOS]

 

1) Free RADIUS Client:

CentOS:

 yum install freeradius-utils

Ubuntu:

apt-get install freeradius-utils

 

2) Free RADIUS Server:

Add the client device to free RADIUS server:

i) vi /etc/freeradius/3.0/clients.conf 

ii) Append below lines to the file above

#############

client FortiGate-VM64-Xen {
       ipaddr           = 192.168.0.108
       secret           = testing123
}
client sumit-linux-amp {
       ipaddr           = 192.168.0.190
       secret           = testing123
}

############# 

 iii) Add users to the RADIUS server: Append below lines to the file "users"

> vi /etc/freeradius/3.0/users

############# 

sumit1 Cleartext-Password := "password"
sumit2 Cleartext-Password := "password"

 
#############  

iv) restart the free RADIUS services:

Ubuntu: > systemctl restart freeradius  

CentOS: >  systemctl restart freeradius  

                > sudo firewall-cmd --add-service={http,https,radius} --permanent

                > sudo firewall-cmd --reload

3) Test the RADIUS user from the client machine:

Syntax:  radtest  <user>  <password>  <Radius_server_IP>  <NAS_port>  <Device_password>

> radtest sumit1 password 192.168.0.190 0 testing123
