Backtrack basics 12. - Connecting to WPA2 wireless network

Here is a short description, about how to connect to WPA2 protected wireless networks with Backtrack 5. First edit the wpa_supplicant.conf file, where we can set the WiFi parameters:

wpa_supplicant.conf:


ctrl_interface=/var/run/wpa_supplicant


network={
ssid="ssid_name"
psk="pre_shared_key"
key_mgmt=WPA-PSK
proto=WPA2
pairwise=CCMP
group=CCMP
}

Then run the following commands:

root@bt:/etc/wpa_supplicant# ifconfig wlan0 up


root@bt:/etc/wpa_supplicant# wpa_supplicant -B -D wext -i wlan0 -c /etc/wpa_supplicant.conf


root@bt:/etc/wpa_supplicant# dhclient wlan0
