wpa supplicant
From Noah.org
script
This is similar to running wpa_pas expect that it adds scan_ssid=1 to the config and it deletes the plantext password..
#!/bin/bash # # This creates a wpa_supplicant.conf file and # starts the wpa_supplicant daemon to serve it. # TARGET_SSID=$1 PASSWORD=$2 IWFACE=$3 echo "You must add authorized users to 'netdev' group." (echo "ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev"; \ wpa_passphrase "${TARGET_SSID}" "${PASSWORD}" | \ grep -v \#psk | sed '/ssid/a \\tscan_ssid=1') > wpa_${TARGET_SSID}.conf chmod 600 wpa_${TARGET_SSID}.conf ifconfig ${IWFACE} down sleep 1 wpa_supplicant -B -cwpa_${TARGET_SSID}.conf -i${IWFACE} -Dwext sleep 1 ifconfig ${IWFACE} up dhclient ${IWFACE} # vim:set sr et ts=4 sw=4 ft=sh: // See Vim, :help 'modeline'

simple, with restriction on the key type

Finally, start wpa_supplicant to connect to the AP.
