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

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

SYNOPSIS
     wpa_supplicant [-BdehLqvw]	[-f debug-file]	-i ifname -c config-file
		    [-N	-i ifname -c config-file ...]

DESCRIPTION
     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	and can	be
     used to configure static WEP keys based on	identified networks.

     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 de-
	     scription of the configuration file syntax	and contents.

	     Changes to	the configuration file can be reloaded by sending a
	     SIGHUP signal to the wpa_supplicant process or with the
	     wpa_cli(8)	utility, using "wpa_cli	reconfigure".

OPTIONS
     The following options are available:

     -B	     Detach from the controlling terminal and run as a daemon process
	     in	the background.

     -d	     Enable debugging messages.	 If this option	is supplied twice,
	     more verbose messages are displayed.  Messages are	sent to	stdout
	     by	default, even when daemonised.	This can be changed with the
	     -f	flag.

     -e	     Use an external IEEE 802.1X Supplicant program and	disable	the
	     internal Supplicant.  This	option is not normally used.

     -f	     Specifies a file to send debug messages to	when enabled with the
	     -d	flag.

     -h	     Show help text.

     -K	     Include key information in	debugging output.

     -L	     Display the license for this program on the terminal and exit.

     -N	-i ifname -c config-file ...
	     Specify an	additional interface and configuration file.  If mul-
	     tiple interfaces are specified then wpa_supplicant	will manage
	     them all with a single process.

     -q	     Decrease debugging	verbosity (i.e., counteract the	use of the -d
	     flag).

     -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.
