WPA_SUPPLICANT(8) FreeBSD System Manager's Manual WPA_SUPPLICANT(8)


[править] NAME

    wpa_supplicant -- WPA/802.11i Supplicant for wireless network devices

[править] SYNOPSIS

    wpa_supplicant [-BdehLqsvw] -i ifname -c config-file


    The wpa_supplicant utility is an implementation of the WPA Supplicant
    component, i.e., the part that runs in the client stations.  It imple-
    ments WPA key negotiation with a WPA Authenticator and EAP authentication
    with an Authentication Server.  In addition, wpa_supplicant controls the
    roaming and IEEE 802.11 authentication/association support of the wlan(4)
    module and can be used to configure static WEP keys based on identified
    The wpa_supplicant utility is designed to be a ``daemon program that
    runs in the background and acts as the backend component controlling the
    wireless connection.  It supports separate frontend programs such as the
    text-based wpa_cli(8) program.
    The following arguments must be specified on the command line:
    -i ifname
            Use the specified wireless interface.
    -c config-file
            Use the settings in the specified configuration file when manag-
            ing the wireless interface.  See wpa_supplicant.conf(5) for a
            description of the configuration file syntax and contents.
            Changes to the configuration file can be reloaded by sending a
            SIGHUP to the wpa_supplicant process or with the wpa_cli(8) util-
            ity, using ``wpa_cli reconfigure.

[править] OPTIONS

    The following options are available:
    -d      Enable debugging messages.  If this option is supplied twice,
            more verbose messages are displayed.
    -e      Use an external IEEE 802.1X Supplicant program and disable the
            internal Supplicant.  This option is not normally used.
    -h      Show help text.
    -q      Decrease debugging verbosity (i.e., counteract the use of the -d
    -s      Send log messages through syslog(3) instead of to the terminal.
    -v      Display version information on the terminal and exit.
    -w      If the specified interface is not present, wait for it to be
            added; e.g. a cardbus device to be inserted.  This option is not
            normally used; instead, devd(8) should be configured to launch
            wpa_supplicant when a device is created.
    -B      Detach from the controlling terminal and run as a daemon process
            in the background.
    -K      Include key information in debugging output.
    -L      Display the license for this program on the terminal and exit.
