hi, I tried eap-sim authentication on freeradius-server 2.2.0, I followed the steps from https://code.google.com/p/seek-for-android/wiki/EapSimAka I've added lines on the clients.conf client 192.168.1.0/24 { secret = eap-sim shortname = eap-sim } In the config directory /etc/freeradius/modules create a file sim_files with following content: sim_files { simtriplets = "/etc/freeradius/simtriplets.dat" } and then I made the simtrilplets.dat with the same format In the config file default add sim_files directly before eap { ok = return } IP address for AP is 192.168.1.1/24 and I've set up the IP server radius on AP too but I always failed when I was tried to connect AP.
