|
|
.Sh SYNOPSIS
|
|
.Nm
|
|
.Op Fl BdhKtv
|
|
.Op Fl P Ar pidfile
|
|
.Ar config-file ...
|
|
.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
utility
|
|
is an authenticator for IEEE 802.11 networks.
|
|
It provides full support for WPA/IEEE 802.11i and
|
|
can also act as an IEEE 802.1X Authenticator with a suitable
|
|
backend Authentication Server (typically
|
|
.Tn FreeRADIUS ) .
|
|
The
|
|
.Nm
|
|
utility
|
|
implements the authentication protocols that piggyback on top
|
|
of the normal IEEE 802.11 protocol mechanisms.
|
|
To use
|
|
.Nm
|
|
as an authenticator, the underlying device must support some
|
|
basic functionality such as the ability to set security information
|
|
in the 802.11 management frames.
|
|
Beware that not all devices have this support.
|
|
.Pp
|
|
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 frontend,
|
|
.Xr hostapd_cli 8 .
|
|
.Pp
|
|
The following arguments must be specified on the command line:
|
|
.Bl -tag -width indent
|
|
.It Ar config-file
|
|
Use the settings in the specified configuration file; the name of
|
|
the specified wireless interface is contained in this file.
|
|
See
|
|
.Xr hostapd.conf 5
|
|
for a description of the configuration file syntax.
|
|
.Pp
|
|
Changes to the configuration file can be reloaded by sending a
|
|
.Dv SIGHUP
|
|
to the
|
|
.Nm
|
|
processor or with the
|
|
.Xr hostapd_cli 8
|
|
utility, using
|
|
.Dq Li "hostapd_cli reconfigure" .
|
|
.El
|
|
.Sh OPTIONS
|
|
The options are as follows:
