NAME

       wpa_cli - WPA command line client

SYNOPSIS

       wpa_cli  [ -p path to ctrl sockets ] [ -g path to global ctrl_interface socket ] [ -i ifname ] [ -hvB ] [
       -a action file ] [ -P pid file ] [ -G ping interval ] [ command ... ]

OVERVIEW

       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,
       username/password requests).

       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

COMMAND ARGUMENTS

       -p path
              Change the path where control sockets should be found.

       -g control socket path
              Connect to the global control socket at the  indicated  path  rather  than  an  interface-specific
              control socket.

       -i ifname
              Specify the interface that is being configured.  By default, choose the first interface found with
              a control socket in the socket path.

       -h     Help.  Show a usage message.

       -v     Show version information.

       -B     Run as a daemon in the background.

       -a file
              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 file
              Set the location of the PID file.

       -G ping interval
              Set the interval (in seconds) at which wpa_cli pings the supplicant.

       command
              Run a command.  The available commands are listed in the next section.
