SYNOPSIS

wpa_supplicant [-BdehLqvw] -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 implements 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 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:

-i ifname
Use the specified wireless interface.
-c config-file
Use the settings in the specified configuration file when managing 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) utility, using ""wpa_cli reconfigure"".

OPTIONS

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