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]] [-M -i ifpattern -c config-file [-D driver]] ...


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. If combined with -M, this is actually a pattern used to match an interface when it becomes available, for example 'wlan*'. -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".


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 ('bsd' or 'wired') -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. -M Start describing a new interface matching given pattern. -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. -u Enable DBus control interface. -v Display version information on the terminal and exit. -W 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. DragonFly 5.9-DEVELOPMENT May 21, 2020 DragonFly 5.9-DEVELOPMENT
