LANforge WiFi testing with HotSpot 2.0

Goal: Authenticate using HotSpot 2.0, 802.11u, and 802.1x EAP-TTLS.

Simplest HotSpot 2.0 example using EAP-TTLS where the client only needs a username and password to authenticate.

There are four main components to setting up this test:

  1. One or more Access Points
  2. A RADIUS Server
  3. A DHCP Server
  4. One or more Clients

In this example, one LANforge system will fulfill the roles of APs, RADIUS and DHCP servers while another LANforge system will fulfill the role of Client devices.

Any one of the four main components can be replaced by 3rd party devices as required.

    3. Add DHCP Service for the second AP: screenshot
  3. Verify Freeradius is running and setup /etc/hosts file.
    1. Freeradius is installed on the LANforge system by default with the TTLS user/pass credentials
      testuser / testpasswd. screenshot
    2. Edit /etc/hosts to add local domain names for each AP. screenshot
  4. Create EAP-TTLS (802.1X username + password authentication) for one or more clients.
    1. Create stations. screenshot
    2. The SSID and Key/Password do not need to be configured when using HotSpot 2.0: screenshot
    3. Select the Advanced Configuration tab in the Port-Modify window and configure the 802.1x, 802.11u, HotSpot 2.0 and other information. The EAP Identity and EAP Password must match the configuration on your RADIUS server. screenshot
    4. The next station is setup with the HESSID and Realm/Domain of the second access point. screenshot
    5. Verify stations connect and obtain DHCP IP address configuration. screenshot
