wpa_cli - text-based frontend program for interacting with wpa_supplicant

wpa_cli is a text-based frontend program for interacting with
wpa_supplicant. It is used to query current status, change configuration,
trigger events, and request interactive user input.
wpa_cli can show the current authentication status, selected security
mode, dot11 and dot1x MIBs, etc. In addition, it can configure some
variables like EAPOL state machine parameters and trigger events like
reassociation and IEEE 802.1X logoff/logon. wpa_cli provides a user
interface to request authentication information, like username and
password, if these are not included in the configuration. This can be
used to implement, e.g., one-time-passwords or generic token card
authentication where the authentication is based on a challenge-response
that uses an external device for generating the response.
The control interface of wpa_supplicant can be configured to allow non-
root user access (ctrl_interface GROUP= parameter in the configuration
file). This makes it possible to run wpa_cli with a normal user account.
wpa_cli supports two modes: interactive and command line. Both modes
share the same command set and the main difference is in interactive mode
providing access to unsolicited messages (event messages,
Interactive mode is started when wpa_cli is executed without including
the command as a command line parameter. Commands are then entered on the
wpa_cli prompt. In command line mode, the same commands are entered as
command line arguments for wpa_cli.
INTERACTIVE AUTHENTICATION PARAMETERS REQUEST
When wpa_supplicant need authentication parameters, like username and
password, which are not present in the configuration file, it sends a
request message to all attached frontend programs, e.g., wpa_cli in
interactive mode. wpa_cli shows these requests with "CTRL-
REQ-<type>-<id>:<text>" prefix. <type> is IDENTITY, PASSWORD, or OTP
(one-time-password). <id> is a unique identifier for the current network.
<text> is description of the request. In case of OTP request, it includes
the challenge from the authentication server.
The reply to these requests can be given with identity, password, and otp
commands. <id> needs to be copied from the matching request. password and
otp commands can be used regardless of whether the request was for
PASSWORD or OTP. The main difference between these two commands is that
values given with password are remembered as long as wpa_supplicant is
running whereas values given with otp are used only once and then
forgotten, i.e., wpa_supplicant will ask frontend for a new value for
every use. This can be used to implement one-time-password lists and
generic token card -based authentication.
Example request for password and a matching reply:
CTRL-REQ-PASSWORD-1:Password needed for SSID foobar
> password 1 mysecretpassword
Example request for generic token card challenge-response:
CTRL-REQ-OTP-2:Challenge 1235663 needed for SSID foobar
> otp 2 9876
-p Change the path where control sockets should be found.
-g Connect to the global control socket at the indicated path rather
than an interface-specific control socket.
-i Specify the interface that is being configured. By default,
choose the first interface found with a control socket in the
-h Help. Show a usage message.
-v Show version information.
-B Run as a daemon in the background.
-a Run in daemon mode executing the action file based on events from
wpa_supplicant. The specified file will be executed with the
first argument set to interface name and second to "CONNECTED" or
"DISCONNECTED" depending on the event. This can be used to
execute networking tools required to configure the interface.
Additionally, three environmental variables are available to the
file: WPA_CTRL_DIR, WPA_ID, and WPA_ID_STR. WPA_CTRL_DIR contains
the absolute path to the ctrl_interface socket. WPA_ID contains
the unique network_id identifier assigned to the active network,
and WPA_ID_STR contains the content of the id_str option.
-P Set the location of the PID file.
-G Set the interval (in seconds) at which wpa_cli pings the
