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

     wpa_supplicant — WPA/802.11i Supplicant for wireless network devices

     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 wire‐
     less 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”.

     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.

     The wpa_supplicant utility first appeared in FreeBSD 6.0.

     The wpa_supplicant utility was written by Jouni Malinen ⟨j@w1.fi⟩.	 This
     manual page is derived from the README file included in the
     wpa_supplicant distribution.
