hi Alan,

I'm sorry for the late response.

> fix them

I was tried to fix the reading pairlist as much as I can.
in the user files, I made followed this format:
1510101425520064 at wlan.mnc101.mcc510.3gppnetwork.org  EAP-Type :=SIM,
EAP-Sim-Rand1 :=0x3FFA1C8555A04485841D99585B59FA04, EAP-Sim-SRES1 :=
0x2A59e3a0, EAP-Sim-KC1 :=0x637f534f6375c400, EAP-Sim-Rand2

EAP-Sim-KC3 :=0x83EF559E1B33A000

if I see the log that's different from before in the "reading pairlist file
/etc/freeradius/users" line,
that's mean it has been fixed?

​yes, I see the eap conversation after read it again,
but would you tell me​ how to configure so my client doing eap-sim?

actually, I used Freeradius-server 2.2.0 on my virtual box, and my mine OS
is windows 7
​first I just want connect to my AP, when I was trying to connect the AP,
for the network authentication I have to insert username & password,
in the username should I insert the IMSI? I just insert eap-sim for the
username & password, so the log show the username is eap-sim.

​here's the log after I changed the users
