Manual Configuration

These are generic instructions for configuring a linux machine to work with AirPennNet.  Please note these are general guidelines and you might need to alter them for the files in your specific distribution. FYI - If you are having trouble with Ubuntu 12.04+ you should not be using these instructions.

  1. You need an 802.1X supplicant.  Many versions of Linux come with wpa_supplicant.  Put the following text in wpa_supplicant.conf.  This file might be in /etc/wpa_supplicant.conf or /etc/wpa_supplicant/wpa_supplicant.conf or similar location:
    ctrl_interface=/var/run/wpa_supplicant.conf
    ctrl_interface_group=0
    eapol_version=2
    ap_scan=1

    network={
    priority=1
    ssid="AirPennNet"
    key_mgmt=WPA-EAP
    eap=TTLS
    phase2="auth=PAP"
    identity="<YOUR_PENNNAME>"
    ca_cert="/etc/ssl/certs/UTN_USERFirst_Hardware_Root_CA.pem"
    }
  2. Edit your network interfaces file to refer to wpa_supplicant.

    Example 1: Ubuntu

    The interfaces file would be /etc/network/interfaces.
    The following text goes under the wireless device section of this file:
    wpa-driver wext
    wpa-conf /etc/wpa_supplicant.conf

    Example 2: Gentoo
    The interfaces file might be /etc/conf.d/net
    The following text goes into this file:
    config_wlan0=("dhcp")
    modules=("wpa_supplicant")
    wpa_supplicant_wlan0="-Dwext"
    wpa_timeout_wlan0=60
  3. In one window, start the command wpa_cli.
  4. Bring your wireless interface up.  Do this with ifup or ifconfig, however you typically start your interface
  5. In the wpa_cli window, issue the password command:
    password 1 <your pennkey password>
