NAME
wpa_supplicant – WPA/802.11i Supplicant for wireless network devices
SYNOPSIS
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] ...]
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:
- -b
-
Optional bridge interface name.
- -B
-
Detach from the controlling terminal and run as a daemon process in the background.
- -d
-
Enable debugging messages. If this option is supplied twice, more verbose messages are displayed.
- -D
-
Driver name (can be multiple drivers: nl80211,wext).
- -f
-
Log output to debug file instead of stdout.
- -g
-
Global ctrl_interface.
- -h
-
Show help text.
- -K
-
Include key information in debugging output.
- -L
-
Display the license for this program on the terminal and exit.
- -N
-
Start describing a new interface.
- -o
-
Overrides driver parameter for new interfaces.
- -O
-
Override ctrl_interface parameter for new interfaces.
- -p
-
Specify driver parameters.
- -P
-
File in which to save the process PID.
- -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.
