.Dd November 7, 2012 .Dt WPA_SUPPLICANT 8 .Os .Sh NAME .Nm wpa_supplicant .Nd "WPA/802.11i Supplicant for wireless network devices" .Sh SYNOPSIS .Nm .Op Fl BdhKLqstuvW .Op Fl b Ar br_ifname .Fl c Ar config-file .Op Fl C Ar ctrl .Op Fl D Ar driver .Op Fl f Ar debug file .Op Fl g Ar global ctrl .Fl i Ar ifname .Op Fl o Ar override driver .Op Fl O Ar override ctrl .Op Fl P Ar pid file .Oo Fl N .Fl i Ar ifname .Fl c Ar config-file .Op Fl C Ar ctrl .Op Fl D driver .Op Fl p Ar driver_param .Op Fl b Ar br_ifname .No ... .Oc .Sh DESCRIPTION The .Nm 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, .Nm controls the roaming and IEEE 802.11 authentication/association support of the .Xr wlan 4 module and can be used to configure static WEP keys based on identified networks.
p The .Nm utility is designed to be a .Dq 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 .Xr wpa_cli 8 program.
p The following arguments must be specified on the command line: l -tag -width indent t Fl i Ar ifname Use the specified wireless interface. t Fl c Ar config-file Use the settings in the specified configuration file when managing the wireless interface. See .Xr wpa_supplicant.conf 5 for a description of the configuration file syntax and contents.
p Changes to the configuration file can be reloaded by sending a .Dv SIGHUP to the .Nm process or with the .Xr wpa_cli 8 utility, using .Dq Li "wpa_cli reconfigure" . .El .Sh OPTIONS The following options are available: l -tag -width indent t Fl b Optional bridge interface name. t Fl B Detach from the controlling terminal and run as a daemon process in the background. t Fl d Enable debugging messages. If this option is supplied twice, more verbose messages are displayed. t Fl D Driver name (can be multiple drivers: nl80211,wext). t Fl f Log output to debug file instead of stdout. t Fl g Global ctrl_interface. t Fl h Show help text. t Fl K Include key information in debugging output. t Fl L Display the license for this program on the terminal and exit. t Fl N Start describing a new interface. t Fl o Overrides driver parameter for new interfaces. t Fl O Override ctrl_interface parameter for new interfaces. t Fl p Specify driver parameters. t Fl P File in which to save the process PID. t Fl q Decrease debugging verbosity (i.e., counteract the use of the .Fl d flag). t Fl s Send log messages through .Xr syslog 3 instead of to the terminal. t Fl t Include timestamp in debug messages. t Fl u Enable DBus control interface. t Fl v Display version information on the terminal and exit. t Fl W Wait for a control interface monitor before starting. .El .Sh SEE ALSO .Xr an 4 , .Xr ath 4 , .Xr ipw 4 , .Xr iwi 4 , .Xr ral 4 , .Xr rum 4 , .Xr ural 4 , .Xr wi 4 , .Xr wlan 4 , .Xr wpi 4 , .Xr zyd 4 , .Xr wpa_supplicant.conf 5 , .Xr devd 8 , .Xr ifconfig 8 , .Xr wpa_cli 8 .Sh HISTORY The .Nm utility first appeared in .Fx 6.0 . .Sh AUTHORS The .Nm utility was written by .An Jouni Malinen Aq j@w1.fi .
