 +====== Setup of the UNIBZ Wireless LAN for Linux WPA ======
  
 +Security used within the WLAN Network: WPA/WPA2 + PEAP + MSCHAPv2
 +
 +  * Wireless Network SSID: **ScientificNetworkSouthTyrol**
 +  * Security: **WPA/WPA 2 Enterprise**
 +  * Authentication: **Protected EAP (PEAP)**
 +  * Inner Authentication: **MSCHAPv2**
 +  * Certificate: **NONE**
 +  * Username: **<unibz-login>**
 +  * Password: **<unibz-password>**
 +  * IP Address: **Automatic (DHCP)**
 +
 +===== 
 +Pre-requisites =====
 +
 +  * Drivers for your Wireless Adapter and Requirements, installed and configured.
 +
 +   - Intel PRO/Wireless 2100 802.11b (Centrino) http://ipw2100.sourceforge.net/
 +   - Intel PRO/Wireless 2200 802.11g and 2915 802.11ag (Centrino) http://ipw2200.sourceforge.net/
 +   - Intersil PrismII driver with HostAP mode http://hostap.epitest.fi/
 +   - Atheros MADWiFi driver (most cards with 802.11a or 108 Mb/s) http://madwifi.org/
 +   - WLAN Cards using ndiswrapper http://ndiswrapper.sourceforge.net/mediawiki/index.php/Main_Page
 +
 +  * Linux Software for the Authentication: [[http://hostap.epitest.fi/wpa_supplicant/|wpa_supplicant]]. It is a WPA Supplicant with support for WPA and WPA2 (IEEE 802.11i/RSN) 
 +
 +  * A good Networkanager GUI and front-end of wpa_supplicant is [[http://www.gnome.org/projects/NetworkManager/|NetworKManager]]. A list of [[https://wiki.gnome.org/Projects/NetworkManager/Hardware|Supported Wireless Cards & Drivers]] is also available. A wiki about NetworkManager can be found in section [[#Using NetworkManager|Using NetworkManager]]

 +=====
 += (K)(X)Ubuntu < 9.10 Manually ======
 +
 +===== Installing wpa_supplicant =====
 +
 +1. apt-get install wpa_supplicant
 +
 +2. Configure /etc/wpa_supplicant.conf
 +
 +Download {{public:AddTrust_External_Root.pem|AddTrust_External_Root.pem}} Certificate if you do not have it!
 +
 +less /etc/wpa_supplicant.conf
 +
 +<code>
 +ctrl_interface=/var/run/wpa_supplicant
 +ctrl_interface_group=0
 +eapol_version=1
 +ap_scan=1
 +fast_reauth=1
 +
 +network={
 +        disabled=0
 +        ssid="ScientificNetworkSouthTyrol"
 +        proto=WPA
 +        key_mgmt=WPA-EAP
 +        auth_alg=OPEN
 +        eap=PEAP
 +        identity="unibzlogin@unibz.it"
 +        password="unibzpassword"
 +        ca_cert="/etc/ssl/certs/AddTrust_External_Root.pem"
 +        phase1="peaplabel=0 peapver=0"
 +        phase2="auth=MSCHAPV2"
 +        priority=10
 +}
 +</code>
 +
 +3. Bring Interface (eth1/wlan, etc.) up
 +
 +  sudo ifconfig eth1 up
 +
 +4. Start wpa_supplicant
 +
 +   sudo wpa_supplicant -D wext -i eth1 -c /etc/wpa_supplicant.conf
 +
 +5. Get an IP Address
 +
 +   sudo dhclient3 eth1
 +
 +
 +====== Configuration for Wired Authentication 802.1x (Cable) ======
 +
 +This is the same Authentication Method as Wireless, but here we\\
 +use an Ethernet cable.
 +
 +===== Using Network Manager =====
 +
 +Try this first if you are using a Ubuntu => 11.10.
 +
 +Network Manager has the ability to be configured for 802.1x Authentication.
 +
 +Basic steps:
 +
 +  * Click on the Network Symbol (2 Arrows) in the upper right task-bar (either with left/right mouse click)
 +  * Edit Connections... in Network Manager
 +  * In the first Tab: Wired press Add Button
 +  * Fill out Connection name: <hostel>
 +  * Go to 2nd tab 802.1X Security, tick: Use 802.1X security for this connection
 +  * Authentication: Protected EAP (PEAP)
 +  * CA certificate: AddTrust_External_Root.pem (located in /etc/ssl/certs/AddTrust_External_Root.pem)
 +  * PEAP version: Automatic
 +  * Inner authentication: MSCHAPv2
 +  * Username: <your-unibz-login>
 +  * Password: <your-unibz-password>
 +  * Save...
 +  * Click again on the Network Symbol and select the newly create Connection
 +
 +{{:public:nm_802-1x_1.png?direct&200|Network Manager}}
 +{{:public:nm_802-1x_2.png?direct&200|Add Connection}}
 +{{:public:nm_802-1x_3.png?direct&200|Configure}}
 +{{:public:nm_802-1x_4.png?direct&200|Select newly create Connection}}
 +
 +
 +===== Manual Configuration =====
 +
 +For the more "experienced" users!!
 +
 +
 +Make sure you have installed wpasupplicant and wpagui
 +
 +   sudo apt-get install wpa_supplicant wpa_gui
 +
 +Edit the configuration file: /etc/wpasupplicant/wpa_supplicant.conf
 +
 +   vi /etc/wpa_supplicant/wpa_supplicant.conf
 +
 +<code>
 +ctrl_interface=/var/run/wpa_supplicant
 +ctrl_interface_group=0
 +eapol_version=1
 +ap_scan=0
 +fast_reauth=1
 +
 +network={
 +        eap=PEAP
 +        eapol_flags=0
 +        phase1="peaplabel=0"
 +        phase2="auth=MSCHAPV2"
 +        priority=10
 +        key_mgmt=IEEE8021X
 +        auth_alg=OPEN
 +}
 +</code>
 +
 +Now execute the following commands:
 +
 +Starts wpa_supplicant with wired driver (-D wired) and in daemon mode (-B)
 +   * sudo wpa_supplicant -D wired -c /etc/wpa_supplicant/wpa_supplicant.conf -i eth0 -B
 +
 +Start wpa_gui to enter username and password
 +   * sudo wpa_gui
 +   * Login with username@unibz.it and password
 +Get an IP Address
 +   * sudo dhclient3 eth0
