We will need a RADIUS server for orchestrating WPA-Enterprise attacks. The most widely used open source RADIUS server is FreeRADIUS. However, setting it up is difficult and configuring it for each attack can be tedious.

Joshua Wright, a well-known security researcher, created a patch for FreeRADIUS that makes it easier to set up and conduct attacks. This patch was released as the FreeRADIUS-WPE (Wireless Pwnage Edition). Kali doesn't naturally come with FreeRADIUS-WPE, so you need to perform the following steps to set up FreeRADIUS-WPE:

Once it is downloaded, install it with dpkg –i freeradius-server-wpe_2.1.12-1_i386.deb followed by ldconfig:

Let's now quickly set up the RADIUS server on Kali.
