wireles /wpa_supplicant - where to start?

Hi,

I'm trying to set myself up on my University's wireless network. I can successfully connect to my home wireless using:

iwconfig ath0 key 676bd87bc0dd5315f1cd8de794 dhclient ath0

and to unencrypted public access points using:

ifconfig ath0 down
iwconfig ath0 key off
ifconfig ath0 up
iwconfig ath0 ap any
dhclient ath0

However, my University uses WPA, TKIP, PEAP and EAP-MSCHAP v2. I was advised to try network manager, but I couldn't get either network-manager-gnome or kdenetwork-manager to work on my laptop running fluxbox. network-manager-gnome reported that network manager wasn't running even when it was, and kdenetwork-manager reported that it could not find any network devices.

I couldn't figure this out, so I removed network manager et al and installed wpa_supplicant. I read the man page, and wrote the following wpa_supplicant.conf script:

ctrl_interface=/var/run/wpa_supplicant
ctrl_interface_group=tyler

network={

    ssid="SMU_PUBLIC"
    key_mgmt=WPA-EAP IEEE8021X NONE
    pairwise=TKIP
    eap=MSCHAPV2 PEAP
    identity="my-university-user-name"
    password="my-university-password"
}

I've attached the error message for this below. At this point I have no idea what to do. I don't know if the problem is the wpa_supplicant.conf, my wireless driver (madwifi), something needed in interfaces? If anyone can point me in the right direction that would be great.

Thanks,

Tyler
