wpa_supplicant -- WPA/802.11i Supplicant for wireless network devices
wpa_supplicant [-BdehLqvw] -i ifname -c config-file
[-N -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 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.
-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.
-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
-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.
