.Dd March 24, 2008 .Dt WPA_SUPPLICANT 8 .Os .Sh NAME .Nm wpa_supplicant .Nd "WPA/802.11i Supplicant for wireless network devices" .Sh SYNOPSIS .Nm .Op Fl BdehLqsvw .Fl i Ar ifname .Fl c Ar config-file .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 d Enable debugging messages. If this option is supplied twice, more verbose messages are displayed. t Fl e Use an external IEEE 802.1X Supplicant program and disable the internal Supplicant. This option is not normally used. t Fl h Show help text. 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 v Display version information on the terminal and exit. t Fl w If the specified interface is not present, wait for it to be added; e.g. a cardbus device to be inserted. This option is not normally used; instead, .Xr devd 8 should be configured to launch .Nm when a device is created. t Fl B Detach from the controlling terminal and run as a daemon process in the background. t Fl K Include key information in debugging output. t Fl L Display the license for this program on the terminal and exit. .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 .
