30.Sh NAME
31.Nm wpa_cli
32.Nd "text-based frontend program for interacting with wpa_supplicant"
33.Sh SYNOPSIS
34.Nm
35.Op Ar commands
36.Sh DESCRIPTION
37The
38.Nm
39utility
40is a text-based frontend program for interacting with
41.Xr wpa_supplicant 8 .
42It is used to query current status,
43change configuration,
44trigger events,
45and
46request interactive user input.
47.Pp
48The
49.Nm
50utility
51can show the
52current authentication status,
53selected security
54mode, dot11 and dot1x MIBs, etc.
55In addition,
56.Nm
57can configure EAPOL state machine
58parameters and trigger events such as reassociation
59and IEEE 802.1X logoff/logon.
60.Pp
61The
62.Nm
63utility
64provides an interface to supply authentication information
65such as username and password when it is not provided in the
66.Xr wpa_supplicant.conf 5
67configuration file.
68This can be used, for example, to implement
69one-time passwords or generic token card
70authentication where the authentication is based on a
71challenge-response that uses an external device for generating the
72response.
73.Pp
74The
75.Nm
76utility
77supports two modes: interactive and command line.
78Both modes share the same command set and the main difference
79is in interactive mode providing access to unsolicited messages
80(event messages, username/password requests).
81.Pp
82Interactive mode is started when
83.Nm
84is executed without any parameters on the command line.
85Commands are then entered from the controlling terminal in
86response to the
87.Nm
88prompt.
89In command line mode, the same commands are
90entered as command line arguments.
91.Pp
92The control interface of
93.Xr wpa_supplicant 8
94can be configured to allow
95non-root user access by using the
96.Va ctrl_interface_group
97parameter
98in the
99.Xr wpa_supplicant.conf 5
100configuration file.
101This makes it possible to run
102.Nm
103with a normal user account.
104.Sh AUTHENTICATION PARAMETERS
105When
106.Xr wpa_supplicant 8
107needs authentication parameters, such as username and password,
108that are not present in the configuration file, it sends a
109request message to all attached frontend programs, e.g.,
110.Nm
111in interactive mode.
112The
113.Nm
114utility
115shows these requests with a
116.Dq Li CTRL-REQ- Ns Ao Ar type Ac Ns Li - Ns Ao Ar id Ac Ns Li : Ns Aq Ar text
117prefix, where
118.Aq Ar type
119is
120.Li IDENTITY , PASSWORD ,
121or
122.Li OTP
123(One-Time Password),
124.Aq Ar id
125is a unique identifier for the current network,
126.Aq Ar text
127is a description of the request.
128In the case of an
129.Li OTP
130(One-Time Password) request,
131it includes the challenge from the authentication server.
132.Pp
133A user must supply
134.Xr wpa_supplicant 8
135the needed parameters in response to these requests.
136.Pp
137For example,
138.Bd -literal -offset indent
139CTRL-REQ-PASSWORD-1:Password needed for SSID foobar
140> password 1 mysecretpassword
141
142Example request for generic token card challenge-response:
143
144CTRL-REQ-OTP-2:Challenge 1235663 needed for SSID foobar
145> otp 2 9876
146.Ed
147.Sh COMMANDS
148The following commands may be supplied on the command line
149or at a prompt when operating interactively.
150.Bl -tag -width indent
