   5 <p>This is how I connected to the Penn. State wireless network (2.0) with GNU/Linux and wpa_supplicant. Here is the network information from PSU:</p>
   6
   7 <p>
   8 <b>SSID:</b> psu<br>
   9 <b>Security:</b> WPA2-Enterprise<br>
  10 <b>Encryption:</b> AES<br>
  11 <b>Authentication Type:</b> EAP-TTLS<br>
  12 <b>Authentication Protocol:</b> PAP<br>
  13 <b>Certificate Authority:</b> Thawte Premium Server CA
  14 </p>
  15
  16 <p>The following configuration block needs to be entered into /etc/wpa_supplicant.conf:</p>
  17
  18 <pre class="brush: bash">
  19 network={
  20     ssid="psu"
  21     identity="your_access_id_here"
  22     password="your_password_here"
  23     key_mgmt=WPA-EAP
  24     eap=TTLS
  25     phase2="auth=PAP"
  26     ca_cert="/etc/ssl/certs/Thawte_Premium_Server_CA.pem"
  27 }
  28 </pre>

  30 Check that your wireless card is up with `ifconfig` and that you are in range of an access point with `iwlist scan`. You can now connect using wpa_supplicant and dhcpcd. Change the following line to use your wireless driver and interface.
  31
  32 <pre class="brush: bash">
  33 wpa_supplicant -B -D wext -i wlan0 -c /etc/wpa_supplicant.conf
  34 dhcpcd wlan0
  35 </pre>
