WPA_SUPPLICANT(8) System Manager's Manual WPA_SUPPLICANT(8) NAME wpa_supplicant -- WPA/802.11i Supplicant for wireless network devices SYNOPSIS wpa_supplicant [-BdhKLqstvW] [-b br_ifname] [-C ctrl] -c config-file [-D driver] [-e entropy-file] [-f debug-file] [-G global-ctrl-group] [-g global-ctrl] [-I additional-config-file] [-i ifname] [-O override-ctrl] [-o override-driver] [-P pidfile] [-p parameters] [-M [-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 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 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 signal to the wpa_supplicant process or with the wpa_cli(8) utility, using ``wpa_cli reconfigure''. OPTIONS The following options are available: -B Detach from the controlling terminal and run as a daemon process in the background. -b br_ifname Optional bridge interface name. -C ctrl Control interface parameter. -D driver Driver name (can be either bsd or wired) -d Enable debugging messages. If this option is supplied twice, more verbose messages are displayed. Messages are sent to stdout by default, even when daemonised. This can be changed with the -f flag. -e entropy-file Specifies a file to store entropy. -f debug-file Specifies a file to send debug messages to when enabled with the -d flag. -G global-ctrl-group Global control interface group. -g global-ctrl Global control interface. -h Show help text. -I additional-config-file Additional configuration file. -K Include key information in debugging output. -L Display the license for this program on the terminal and exit. -M [-i matchifname] -c config-file ... Matches the interface name using fnmatch(3), or all interfaces if -i is not specified. If multiple interfaces are matched then wpa_supplicant will manage them all with a single process. -N -i ifname -c config-file ... Specify an additional interface and configuration file. If multiple interfaces are specified then wpa_supplicant will manage them all with a single process. -O override-ctrl Override ctrl_interface parameter for new interface. -o override-driver Override driver paramter for new interface. -P pidfile File in which to save the process PID. -p parameters Specify driver parameters. -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.
