getting wpa to work

here's my wpa conf file, airpennnet.conf:

ctrl_interface=/var/run/wpa_supplicant
ctrl_interface_group=0
eapol_version=2
ap_scan=1

network={
  priority=2
  ssid="AirPennNet"
  key_mgmt=IEEE8021X
  eap=TTLS
  <email address hidden>"
  phase2="auth=PAP"
  identity="//my user name//"
  password="//my password//"
  ca_cert="/home/harsha/TSR/ThawtePremiumServerCA.cer"
}

here's what happens when i try to run wpa_supplicant :

harsha@ubuntu:~$ sudo wpa_supplicant -dd -c /etc/airpennnet.conf -i eth1 -d madwifi -B -K //replacing madwifi with wext or broadcom gives the same result

Hey how did you get it to work on the AirPennNet exactly? i tried using the settings for lehigh, but i couldnt get it work. Did you just modify your settings? As for the certificate, did you have to download that from a windows machine and then transfer it to your ubuntu setup? Did you use madwifi or wext? Any help is appreciated

sorry for the very late reply, i have been away from my laptop for a long time, so i couldn't find the exact settings. just in case you haven't configured it already and for future reference, here's a list of steps which worked for me
- register your MAC address with penn, (instructions here http://www.sas.upenn.edu/computing/wireless/user_mac_registration.html )
- create a airpennnet.conf file as specified here, http://www.sas.upenn.edu/computing/wireless/airpennnet_linux.html with your pennid and password in it
- download certificates from thawte site, you might find many certificates with similar names - the one you'll need is the one mentioned in the above configuration file
- change the /etc/network/interfaces file as mentioned in my previous post, this is the crucial step which made it work for me, originally i was trying wpa _supplicant directly but it didn't work for some reason
     for reference here's my /etc/network/interfaces file after i changed it as mentioned in the article
---
# The loopback network interface
auto lo
iface lo inet loopback

auto eth1 #eth1 is the wireless port
iface eth1 inet dhcp
wpa-driver wext #you might need to replace this
wpa-conf /etc/airpennnet.conf #this should be changed to wherever you have put the .conf file created in the above step
---
- after this do a sudo /etc/init.d/networking restart
at this point, it started working

if this does work out you might consider creating a script with a short name which runs the above command, or add an item to the desktop/ gnome panel(with theapplication in terminal option) which executes the above command

if it still doesn't work out, it might be that the wireless card isn't being recognized(which is unlikely as ubuntu seems to recognize intel cards) or there was an error in carrying out one of the above steps
