TTUnet Wifi Protected Access for Linux

Requirements

• Kernel support for your specific wireless device. If you can run iwconfig (as root) and get information for a device named eth1, ath0, wlan0, or something similar, then you're in good shape. (See http://www.tldp.org/HOWTO/Wireless-HOWTO.html for more information.)
• An installed copy of wpa_supplicant. If you don't have it, try to get it through your distro's package repositories first. If that doesn't work, you'll have to download it from http://hostap.epitest.fi/wpa_supplicant/ and compile it from source.

Configuration

Find your wpa_supplicant configuration file, which will either be /etc/wpa_supplicant.conf or /etc/wpa_supplicant/wpa_supplicant.conf, and add the following options. Remember to replace ERAIDER_USER with your eraider username and ERAIDER_PASS with your eraider password.

Example /etc/wpa_supplicant.conf

ctrl_interface=/var/run/wpa_supplicant ap_scan=1 fast_reauth=0 network={     ssid="TTUnet"     scan_ssid=1     proto=WPA     key_mgmt=IEEE8021X     auth_alg=OPEN     group=WEP104 WEP40     eap=PEAP     identity="ERAIDER_USER@ttu"     password="ERAIDER_PASS"     phase1="peaplabel=0"     phase2="auth=MSCHAPV2" }

General Connection Procedure

To connect to the wireless network, the basic procedure is to start wpa_supplicant (either as a daemon or otherwise), wait until it's connected to the TTUnet AP, and then run your DHCP client (probably dhclient or dhcpcd) to get an IP address. (The example uses eth1 and /etc/wpa_supplicant.conf. See the manpage for wpa_supplicant for more information.)

Example of connecting to TTUnet wifi

user@linux:~$ su -l root root@linux:~$ wpa_supplicant -c/etc/wpa_supplicant.conf -Dwext -ieth1 root@linux:~$ dhclient eth1
