WPA_SUPPLICANT(8) MidnightBSD System Manager’s Manual WPA_SUPPLICANT(8)
wpa_supplicant — WPA/802.11i Supplicant for wireless network devices
wpa_supplicant [−BdehLqvw] −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 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:
Use the specified wireless interface.
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’’.
The following options are available:
Enable debugging messages. If this option is supplied twice, more verbose messages are displayed.
Use an external IEEE 802.1X Supplicant program and disable the internal Supplicant. This option is not normally used.
Show help text.
Decrease debugging verbosity (i.e., counteract the use of the −d flag).
Display version information on the terminal and exit.
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.
Detach from the controlling terminal and run as a daemon process in the background.
Include key information in debugging output.
Display the license for this program on the terminal and exit.

The wpa_supplicant utility first appeared in FreeBSD 6.0.
The wpa_supplicant utility was written by Jouni Malinen 〈firstname.lastname@example.org〉. This manual page is derived from the README file included in the wpa_supplicant distribution.
