WPA_SUPPLICANT(8) MidnightBSD System Manager’s Manual WPA_SUPPLICANT(8)

NAME

wpa_supplicant — WPA/802.11i Supplicant for wireless network devices

SYNOPSIS

wpa_supplicant [−BdehLqvw] −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.
