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:
Use the specified wireless interface.
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:
-b Optional bridge interface name.
-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.
-D Driver name (bsd, ndis etc.)
-f Log output to debug file instead of stdout.
-g Global ctrl_interface.
-h Show help text.
-K Include key information in debugging output.
-L Display the license for this program on the terminal and exit.
-N Start describing a new interface.
-o Overrides driver parameter for new interfaces.
-O Override ctrl_interface parameter for new interfaces.
-p Specify driver parameters.
-P File in which to save the process PID.
-q Decrease debugging verbosity (i.e., counteract the use of the -d
-s Send log messages through syslog(3) instead of to the terminal.
-t Include timestamp in debug messages.
-u Enable DBus control interface.
-v Display version information on the terminal and exit.
-W Wait for a control interface monitor before starting.
