无线wpa2-psk,wep在interfaces中的总结

1.wep设置
# ifconfig wlan0 up
# iwconfig wlan0 essid TP-LINK key 1122334455
# dhclient wlan0

--wep在/etc/network/interfaces里面的设置
auto wlan0
iface wlan0 inet dhcp
    wireless-essid dlink
    wireless-key xxxxxxxxxx

2.wpa2-psk设置
# wpa_passphrase [ ssid ] [ passphrase ] >> /etc/wpa_supplicant/wpa_supplicant.conf
# ifconfig wlan0 up
# iwconfig wlan0 essid D-LINK
# wpa_supplicant -B -D wext -i wlan0 -c /etc/wpa_supplicant/wpa_supplicant.conf
# dhclient wlan0

--关于wpa2-psk在/etc/network/interfaces里面的设置
auto wlan0
iface wlan0 inet dhcp
    wpa-driver wext
    wpa-ssid D-LINK
    wpa-psk xxxxxxxxxx

wpa-psk 编码在运行wpa_passphrase 后，可以在wpa_supplicant.conf里面查到。/etc/network/interfaces设置过后开机就自动上网，不用命令一行一行的敲，很方便。
