WPA_SUPPLICANT(8) BSD System Manager's Manual WPA_SUPPLICANT(8) NAME wpa_supplicant -- WPA/802.11i Supplicant for wireless network devices SYNOPSIS wpa_supplicant [-BdehLqvw] -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 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 wire- less 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 de- scription 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) util- ity, using "wpa_cli reconfigure". OPTIONS The following options are available: -d Enable debugging messages. If this option is supplied twice, more verbose messages are displayed. -e Use an external IEEE 802.1X Supplicant program and disable the internal Supplicant. This option is not normally used. -h Show help text. -q Decrease debugging verbosity (i.e., counteract the use of the -d flag). -v Display version information on the terminal and exit. -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, devd(8) should be configured to launch wpa_supplicant when a device is created. -B Detach from the controlling terminal and run as a daemon process in the background. -K Include key information in debugging output. -L Display the license for this program on the terminal and exit. -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.
