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 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 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 manag-
             ing 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 mul-
             tiple 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.
