wpa_supplicant — WPA/802.11i Supplicant for wireless network devices

wpa_supplicant [-BdhKLqstuvW] [-b br_ifname] -c config-file [-C ctrl] [-D driver] [-f debug file] [-g global ctrl] -i ifname [-o override driver] [-O override ctrl] [-P pid file] [-N -i ifname -c config-file [-C ctrl] [-D -driver] [-p driver_param] [-b br_ifname] ...]

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:

ifname
Use the specified wireless interface.
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”.

The following options are available:

Optional bridge interface name.
Detach from the controlling terminal and run as a daemon process in the background.
Enable debugging messages. If this option is supplied twice, more verbose messages are displayed.
Driver name (bsd, ndis etc.)
Log output to debug file instead of stdout.
Global ctrl_interface.
Show help text.
Include key information in debugging output.
Display the license for this program on the terminal and exit.
Start describing a new interface.
Overrides driver parameter for new interfaces.
Override ctrl_interface parameter for new interfaces.
Specify driver parameters.
File in which to save the process PID.
Decrease debugging verbosity (i.e., counteract the use of the -d flag).
Send log messages through syslog(3) instead of to the terminal.
Include timestamp in debug messages.
Enable DBus control interface.
Display version information on the terminal and exit.
Wait for a control interface monitor before starting.

The wpa_supplicant utility first appeared in FreeBSD 6.0.

The wpa_supplicant utility was written by Jouni Malinen <j@w1.fi>. This manual page is derived from the README file included in the wpa_supplicant distribution.
