Accounting-Request with invalid signature!

[艳华 杨]

Hi, everyone
   
  I use Hostap(0.2.0, the hostapd is 0.4.7)+Freeradius(1.0.2)+Xsupplicant(1.0.1_, and both of the hostap and freeradius are located in the same machine. So I set 127.0.0.1 in clients.conf as freeradius server's client and set 127.0.0.1 as the radius server in hostapd.conf, and the secret of them is the same. But When I setup the authentication, I got the following informantion on radius server:
   
  rad_recv: Accounting-Request packet from host 127.0.0.1:32773, id=0, length=70
Received Accounting-Request packet from 127.0.0.1 with invalid signature!  (Shared secret is incorrect.)
Server rejecting request 1.
Finished request 1
   
  Then I checked the "Shared secret" set in both configure file, they are the same. Why did the error appear?
   
  On the other hand, everytime I run the xsupplicant, the destination MAC address will change for a while. And this is what I got:

  Why the destination MAC address could change? And I have checked the address "44 44 44 44 44 44" which means no network is detected. So what's wrong?
   
  Anyone can help me? Thanks a lot!
