WPA_SUPPLICANT + WPA_CLI - Control interface commands

Following commands can be used with wpa_cli

PING

This command can be used to test whether wpa_supplicant is replying to the control interface commands. The expected reply is PING if the connection is open and wpa_supplicant is processing commands.

STATUS

Request current status information. The output is a text block with each line in variable=value format. For example:

bssid=02:00:01:02:03:04

ssid=test network

pairwise_cipher=CCMP

group_cipher=CCMP

key_mgmt=WPA-PSK

wpa_state=COMPLETED

LIST_NETWORKS

List configured networks.

network id / ssid / bssid / flags

0 example network any [CURRENT]

(note: fields are separated with tabs)

SCAN

Request a new BSS scan.

SCAN_RESULTS

Get the latest scan results.

bssid / frequency / signal level / flags / ssid

00:09:5b:95:e0:4e 2412 208 [WPA-PSK-CCMP] jkm private

02:55:24:33:77:a3 2462 187 [WPA-PSK-TKIP] testing

00:09:5b:95:e0:4f 2412 209 jkm guest

(note: fields are separated with tabs)

ADD_NETWORK

Add a new network. This command creates a new network with empty configuration. The new network is disabled and once it has been configured it can be enabled with ENABLE_NETWORK command. ADD_NETWORK returns the network id of the new network or FAIL on failure

SELECT_NETWORK <network_id>

Select a network (disable others). Network id can be received from the LIST_NETWORKS command output.

ENABLE_NETWORK <network_id>

Enable a network. Network id can be received from the LIST_NETWORKS command output.

DISABLE_NETWORK <network_id>

Disable a network. Network id can be received from the LIST_NETWORKS command output. Special network id all can be used to disable all network. .

REMOVE_NETWORK <network_id>

Remove a network. Network id can be received from the LIST_NETWORKS command output. Special network id all can be used to remove all network.

SET_NETWORK <network_id> <variable> <value>

Set network variables. Network id can be received from the LIST_NETWORKS command output. This command uses the same variables and data formats as the configuration file.

• ssid (network name, SSID)

• psk (WPA passphrase or pre-shared key)

• key_mgmt (key management protocol, NONE, WPA-PSK, WPA-EAP)

• proto ( WPA WPA2)

• pairwise ( CCMP TKIP)

• group ( CCMP TKIP WEP40 WEP104)

• wep_key0 ( set wep key for key index 0)

• wep_tx_keyidx ( select wep key index)

• frequency ( Channel frequency in megahertz (MHz) for IBSS )

GET_NETWORK <network_id> <variable>

Get network variables. Network id can be received from the LIST_NETWORKS command output.

SAVE_CONFIG

Save the current configuration.

AP_SCAN <ap_scan_value>

Change ap_scan value: 0 = no scanning, 1 = wpa_supplicant requests scans and uses scan results to select the AP, 2 = wpa_supplicant does not use scanning and just requests driver to associate and take care of AP selection
