[superd]

I used hostapd 0.3.9, wpa_supplicant 0.3.9 under freebsd 6.0 to build
my pre-authentication environment, but wpa_supplicant always tell me
pre-authentication timed out.
do any people success building pre-authentication environment?
What OS, hostapd,and wpa_supplicant version do you use?
thx.
