NAME
wpa_supplicant -- WPA/802.11i Supplicant for wireless network devices
SYNOPSIS
wpa_supplicant [-BdhKLqstvW] [-b br_ifname] [-C ctrl] -c config-file
[-D driver] [-e entropy-file] [-f debug-file]
[-G global-ctrl-group] [-g global-ctrl]
[-I additional-config-file] [-i ifname] [-O override-ctrl]
[-o override-driver] [-P pidfile] [-p parameters]
[-M [-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 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:
-i ifname
Use the specified wireless interface.
-c config-file
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''.
OPTIONS
The following options are available:
-B Detach from the controlling terminal and run as a daemon process
in the background.
-b br_ifname
Optional bridge interface name.
-C ctrl
Control interface parameter.
-D driver
Driver name (can be either bsd or wired)
-d Enable debugging messages. If this option is supplied twice,
more verbose messages are displayed. Messages are sent to stdout
by default, even when daemonised. This can be changed with the
-f flag.
-e entropy-file
Specifies a file to store entropy.
-f debug-file
Specifies a file to send debug messages to when enabled with the
-d flag.
-G global-ctrl-group
Global control interface group.
-g global-ctrl
Global control interface.
-h Show help text.
-I additional-config-file
Additional configuration file.
-K Include key information in debugging output.
-L Display the license for this program on the terminal and exit.
-M [-i matchifname] -c config-file ...
Matches the interface name using fnmatch(3), or all interfaces if
-i is not specified. If multiple interfaces are matched then
wpa_supplicant will manage them all with a single process.
-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.
-O override-ctrl
Override ctrl_interface parameter for new interface.
-o override-driver
Override driver paramter for new interface.
-P pidfile
File in which to save the process PID.
-p parameters
Specify driver parameters.
-q Decrease debugging verbosity (i.e., counteract the use of the -d
flag).
-s Send log messages through syslog(3) instead of to the terminal.
-t Include timestamp in debug messages.
-v Display version information on the terminal and exit.
-W Wait for a control interface monitor before starting.
