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: [INT] Called event_core_setup()!

[ALL] Unknown error (-1) [ALL] Clock tick! authWhile=29 heldWhile=59 startWhen=0 curState=LOGOFF [STATE] (global) -> DISCONNECTED 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! Helen --------------------------------- 雅虎1G免费邮箱百分百防垃圾信
