Dear Jouni,

Thank you very much for your kindly help!
It's so nice of you to respond so fast.

The server can work now, but it still has two problems.

After I enable the server using ./hostapd -ddK hostapd.conf,
it will show messages like this:
Configuration file: hostapd.conf
TLS:Trusted root certificates loaded
TLS:Successfully parsed PKCS12 data
TLS:Got certificate from PKCS12:subject='/CN=wifi-server'
TLS:Got private key from PKCS12
TLS:additional certificate from PKCS12:subject='/CN=WiFi-Root-CA'
TLS:additional certificate from 
BSS count 1, BSSID mask ff:ff:ff:ff:ff:ff (0 bits)

test_driver_set_encryption(iface= algo=none idx=1 txkey=1)
test_driver_set_encryption(iface= algo=none idx=2 txkey=1)
test_driver_set_encryption(iface= algo=none idx=3 txkey=1)
Using interface with hwaddr 02:56:20:22:3d:2a and ssid' '
:Setup of interface done.

The line "Could not..." sounds like an error, and the four lines 
"test_driver" sound like we are using WEP encryption.
But I am trying to treat it like a server, it should not show any WEP 
Do I miss any configuration?

I am trying to use EAP-SIM and EAP-AKA, and try EAP-SIM first.
But EAP-SIM will never success.

It will show messages like "Failed to get GSM authenticsation triplets for 
the peer".
I am prettry sure I have store IMSI,Kc,SRES,and RAND in hostapd.sim_db, but 
the error messages means the state machine couldn't find a match item in 
its database. Isn't it odd?
How can I fix it?
I notice that AKA doesn't have the database file, then how could you test 
EAP-AKA without the home encironment?

Please give me some advice.

Thank you so much, your help means a lot to me.

Thank you,
