    NAME

    wpa_cli - WPA command line client
     
    

    SYNOPSIS

    wpa_cli [ -p path to ctrl sockets ] [ -i ifname ] [ -hvB ] [ -a action file ] [ -P pid file ] [ 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 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', 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.
    -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 "CONNECT" or "DISCONNECT" depending on the event. This can be used
    -P file
    Set the location of the PID file.
    command
    Run a command. The available commands are listed in the next section.
