NOTE: I already sent this message to Jouni, but it was too big for the list. 
Here it is with bzip'ed attachements.

It is more likely that it is a Meetinghouse AEGIS server because the 
"official" client of the university is their Windows supplicant. Nontheless, 
please find attached a trial run from 0.2.5. I let it time out and try a 
couple times just to make sure I got everything. Command used 
was:

wpa_supplicant -iwlan0 -c/etc/wpa_supplicant.conf -Dhostap -ddd

Config file:

ctrl_interface=/var/run/wpa_supplicant
ctrl_interface_group=0
eapol_version=1
ap_scan=1
network={
        ssid="osuweb"
        key_mgmt=IEEE8021X
        eap=PEAP
        identity="username"
        password="password"
 # it gets farther in the authentication with the following line
        phase1="peaplabel=0"
 phase2="auth=GTC"
        priority=1
}

Also attached:

tcpdump -vv -i wlan0

Regards,
Andrew

P.S. Don't worry about passwords--I edited them out of the wpa_supplicant log 
but I really can't to the same for tcpdump. Anyway, I'll be changing it once 
I get things up and running.
