Setup FreeRADIUS on Kali Linux for 802.1X Authentication

December 5, 2015

This following video explains how to setup a FreeRADIUS server on Kali Linux. The objective is to use the FreeRADIUS server as an 802.1X authentication server for a simple Wi-Fi network infrastructure.

This solution is very cheap and ideal for home labs or small businesses that want to be able to use the very secured 802.1X authentication for their Wi-Fi networks.

Here is the setup I have used in the lab to test the solution:

1x virtual machine running Kali Linux 4.0
1x Cisco router
1x Cisco WLC 2504 controller
1x Cisco AP 1702
1x Aruba controller 651
1x Aruba AP 105
1x MacBook Air running MacOS 10.11.1
1x Asus Laptop running Windows 8

For this test, we have used the EAP-PEAP[EAP-MSCHAPv2] EAP method. However, you can use other EAP methods with FreeRADIUS. For more details, feel free to have a look at FreeRADIUS documentations.

The following drawing explains how the 802.1X authentication using EAP-PEAP[EAP-MSCHAPv2] works:
