wpa_cli调试工具的使用

2012-06-05 16:26 323 查看
1: run wpa_supplicant first

use the following command:

wpa_supplicant -Dwext -iwlan0 -C/data/system/wpa_supplicant -c/data/misc/wifi/wpa_supplicant.conf

(use “ps”to make sure wpa_supplicant is running )

2: Run the command line tool wpa_cli to connect wifi

wpa_cli -p/data/system/wpa_supplicant -iwlan0

Then , it will let you set network interactively


some common command:


>scan = to scan the neighboring AP

>scan_results = show the scan results

>status = check out the current connection information

>terminate = terminate wpa_supplicant

>quit = exit wpa_cli

>add_network = it will return a network id to you

>set_network <network id> <variable> <value> = set network variables (shows

list of variables when run without arguments),
success will return OK, or will return Fail

>select_network <network id> = select a network (disable others)

>disable_network <network id> = disable a network

>enable_network <network id> = enable a network

3: example


for AP that doesn`t have encryption


>add_network (It will display a network id for you, assume it returns 0)

>set_network 0 ssid “666”

>set_network 0 key_mgmt NONE

>enable_network 0

>quit

if normal, we have connectted to the AP “666”, now you need a IP to access internet, for example:

dhcpcd wlan0

if everything is ok, it will get an IP & can access internet


for AP that has WEP


>add_network (assume returns 1)

>set_network 1 ssid “666”

>set_network 1 key_mgmt NONE

>set_network 1 wep_key0 “your ap passwork”(if usting ASCII, it need double quotation marks, if using hex, then don`t need the double quotation marks)

>set_network 1 wep_tx_keyidx 0

>select_network 1
(optional, remember, if you are connecting with another AP, you should select it to disable the another)

>enable_network 1

and then ,get an IP to access internet


for AP that has WPA-PSK/WPA2-PSK


>add_network (assume returns 2)

>set_network 2 ssid “666”

>set_network 2 psk “your pre-shared key”

>select_network 2
(optional, remember, if you are connecting with another AP, you should select it to disable the another)

>enable_network 2

there is still some others options to be set, but wpa_supplicant will choose the default for you, the default will include all we need to set

and then ,get an IP to access internet

for Hidden AP(补充)

原则上应该只要在上面的基础上去set_network netid scan_ssid 1即可,测试过无加密的Hidden AP,WEP/WPA/WPA2应该道理一样
