AirPennNet Configuration for Ubuntu

These instructions allow Ubuntu Linux users to connect their WiFi enabled notebooks to AirPennNet. Other Linux distribution users often will be able to adapt these instructions for their notebook environments. Although not a supported operating system, XpressConnect does have an option for installing a wireless profile on Ubuntu.

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.

  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>
