wpa_supplicant
- WPA/802.11i Supplicant for wireless network devices
SYNOPSIS
[-BdehLqsvw
]
-i ifname
-c config-file
DESCRIPTION
The
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,
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
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_cli8
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.conf5
for a description of the configuration file syntax and contents.
Changes to the configuration file can be reloaded by sending a
SIGHUP
to the
process or with the
wpa_cli8
utility, 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).
-s
Send log messages through
syslog(3)
instead of to the terminal.
-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
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.
