|

.Nm
|
||||
.Op Fl BddhKtv
|
||||
.Ar config-file ...
|
||||
.Sh DESCRIPTION
|
||||
.Nm
|
||||
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 FreeRADIUS).
|
||||
.Nm
|
||||
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
|
||||
.Nm
|
||||
is designed to be a "daemon" program that runs in the
|
||||
background and acts as the backend component controlling
|
||||
the wireless connection.
|
||||
.Nm
|
||||
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 Fl c 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
|
||||
.Nm SIGHUP
|
||||
to the
|
||||
.Nm
|
||||
processor or with the
|
||||
.Xr hostapd_cli
|
||||
utility, using ``hostapd_cli reconfigure''.
|
||||
.El
|
||||
.Sh OPTIONS
|
||||
The options are as follows:
|
||||
.Bl -tag -width indent
|
||||
.It Fl d
|
||||
Enable debugging messages.
|
||||
If this option is supplied twice more verbose messages are displayed.
|
||||
.It Fl h
|
||||
Show help text.
|
||||
.It Fl t
|
||||
Include timestamps in debugging output.
|
||||
.It Fl v
|
||||
Display version information on the terminal and exit.
|
||||
.It Fl B
|
||||
Detach from the controlling terminal and run as a daemon process
|
||||
in the background.
|
||||
.It Fl K
|
||||
Include key information in debugging output.

|
||||
.Sh DESCRIPTION
|
||||
.Nm
|
||||
is a text-based frontend program for interacting with
|
||||
.Xr hostapd 1 .
|
||||
.Nm
|
||||
is used to query current status.
|
||||
.Pp
|
||||
.Nm
|
||||
can show the

||||
current authentication status,
|
||||
dot11 and dot1x MIBs, etc.
|
||||
.Pp
|
||||
.Nm
|
||||
supports two modes: interactive and command line.
|
||||
Both modes share the same command set.
|
||||
.Pp
|
||||
Interactive mode is started when
|
||||
.Nm
|
||||
is executed without with any parameters on the command line.
|
||||
Commands are then entered from the controlling terminal in
|
||||
response to the
|
||||
.Nm
|
||||
prompt.
|
||||
In command line mode, the same commands are
|
||||
entered as command line arguments.
|
||||
.Sh COMMANDS
|
||||
The following commands may be supplied on the command line
|
||||
or at a prompt when operating interactively.
|
||||
.Bl -tag -width indent
|
||||
.It mib
|
||||
Report MIB variables (dot1x, dot11) for the current interface.
|
||||
