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
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 signal to the wpa_supplicant process or with the
wpa_cli(8) utility, using ``wpa_cli reconfigure''.
The following options are available:
-B Detach from the controlling terminal and run as a daemon process
in the background.
Optional bridge interface name.
Control interface parameter.
Driver name (can be either bsd or wired)
-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
Specifies a file to store entropy.
Specifies a file to send debug messages to when enabled with the
Global control interface group.
Global control interface.
-h Show help text.
Additional configuration file.
-K Include key information in debugging output.
-L Display the license for this program on the terminal and exit.
-M [-i matchifname] -c config-file ...
Matches the interface name using fnmatch(3), or all interfaces if
-i is not specified. If multiple interfaces are matched then
wpa_supplicant will manage them all with a single process.
-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.
Override ctrl_interface parameter for new interface.
Override driver paramter for new interface.
File in which to save the process PID.
Specify driver parameters.
-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.
-v Display version information on the terminal and exit.
-W Wait for a control interface monitor before starting.
