|

.Nm
|
|

|
|
.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
utility
|
|
is a text-based frontend program for interacting with
|
|
.Xr wpa_supplicant 8 .
|
|
It is used to query current status,
|
|
change configuration,
|
|
trigger events,
|
|
and
|
|
request interactive user input.
|
|
.Pp
|
|
The
|
|
.Nm
|
|
utility
|
|
can show the
|
|
current authentication status,
|
|
selected security
|
|
mode, dot11 and dot1x MIBs, etc.
|
|
In addition,
|
|
.Nm
|
|
can configure EAPOL state machine
|
|
parameters and trigger events such as reassociation
|
|
and IEEE 802.1X logoff/logon.
|
|
.Pp
|
|
The
|
|
.Nm
|
|
utility
|
|
provides an interface to supply authentication information
|
|
such as username and password when it is not provided in the
|
|
.Xr wpa_supplicant.conf 5
|
|
configuration file.
|
|
This can be used, for example, to implement
|
|
one-time passwords or generic token card
|
|
authentication where the authentication is based on a
|
|
challenge-response that uses an external device for generating the
|
|
response.
|
|
.Pp
|
|
The
|
|
.Nm
|
|
utility
|
|
supports two modes: interactive and command line.
|
|
Both modes share the same command set and the main difference
|
|
is in interactive mode providing access to unsolicited messages
|
|
(event messages, username/password requests).
|
|
.Pp
|
|
Interactive mode is started when
|
|
.Nm
|
|
is executed without 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.
|
|
.Pp
|
|
The control interface of
|
|
.Xr wpa_supplicant 8
|
|
can be configured to allow
|
|
non-root user access by using the
|
|
.Va ctrl_interface_group
|
|
parameter
|
|
in the
|
|
.Xr wpa_supplicant.conf 5
|
|
configuration file.
|
|
This makes it possible to run
|
|
.Nm
|
|
with a normal user account.
|
|
.Sh AUTHENTICATION PARAMETERS
|
|
When
|
|
.Xr wpa_supplicant 8
|
|
needs authentication parameters, such as username and password,
|
|
that are not present in the configuration file, it sends a
|
|
request message to all attached frontend programs, e.g.,
|
|
.Nm
|
|
in interactive mode.
|
|
The
|
|
.Nm
|
|
utility
|
|
shows these requests with a
|
|
.Dq Li CTRL-REQ- Ns Ao Ar type Ac Ns Li - Ns Ao Ar id Ac Ns Li : Ns Aq Ar text
|
|
prefix, where
|
|
.Aq Ar type
|
|
is
|
|
.Li IDENTITY , PASSWORD ,
|
|
or
|
|
.Li OTP
|
|
(One-Time Password),
|
|
.Aq Ar id
|
|
is a unique identifier for the current network,
|
|
.Aq Ar text
|
|
is a description of the request.
|
|
In the case of an
|
|
.Li OTP
|
|
(One-Time Password) request,
|
|
it includes the challenge from the authentication server.
|
|
.Pp
|
|
A user must supply
|
|
.Xr wpa_supplicant 8
|
|
the needed parameters in response to these requests.
|
|
.Pp
|
|
For example,
|
|
.Bd -literal -offset indent
|
|
CTRL-REQ-PASSWORD-1:Password needed for SSID foobar
|
|
> password 1 mysecretpassword
|
|
|
|
Example request for generic token card challenge-response:
|
|
|
|
CTRL-REQ-OTP-2:Challenge 1235663 needed for SSID foobar
|
|
> otp 2 9876
|
|
.Ed
|
|

|
|
