It is used to query current status, change 33 configuration, trigger events, and request interactive user 34 input.</para> 35 36 <para>wpa_cli can show the current authentication status, selected 37 security mode, dot11 and dot1x MIBs, etc. In addition, it can 38 configure some variables like EAPOL state machine parameters and 39 trigger events like reassociation and IEEE 802.1X 40 logoff/logon. wpa_cli provides a user interface to request 41 authentication information, like username and password, if these 42 are not included in the configuration. This can be used to 43 implement, e.g., one-time-passwords or generic token card 44 authentication where the authentication is based on a 45 challenge-response that uses an external device for generating the 46 response.</para> 47 48 <para>The control interface of wpa_supplicant can be configured to 49 allow non-root user access (ctrl_interface GROUP= parameter in the 50 configuration file). This makes it possible to run wpa_cli with a 51 normal user account.</para> 52 53 <para>wpa_cli supports two modes: interactive and command 54 line. Both modes share the same command set and the main 55 difference is in interactive mode providing access to unsolicited 56 messages (event messages, username/password requests).</para> 57 58 <para>Interactive mode is started when wpa_cli is executed without 59 including the command as a command line parameter. Commands are 60 then entered on the wpa_cli prompt. In command line mode, the same 61 commands are entered as command line arguments for wpa_cli.</para> 62 </refsect1> 63 <refsect1> 64 <title>Interactive authentication parameters request</title> 65 66 <para>When wpa_supplicant need authentication parameters, like 67 username and password, which are not present in the configuration 68 file, it sends a request message to all attached frontend programs, 69 e.g., wpa_cli in interactive mode. wpa_cli shows these requests 70 with "CTRL-REQ-<type>-<id>:<text>" 71 prefix. <type> is IDENTITY, PASSWORD, or OTP 72 (one-time-password). <id> is a unique identifier for the 73 current network. <text> is description of the request. In 74 case of OTP request, it includes the challenge from the 75 authentication server.</para> 76 77 <para>The reply to these requests can be given with 78 <emphasis>identity</emphasis>, <emphasis>password</emphasis>, and 79 <emphasis>otp</emphasis> commands. <id> needs to be copied from 80 the matching request. <emphasis>password</emphasis> and 81 <emphasis>otp</emphasis> commands can be used regardless of whether 82 the request was for PASSWORD or OTP. The main difference between these 83 two commands is that values given with <emphasis>password</emphasis> are 84 remembered as long as wpa_supplicant is running whereas values given 85 with <emphasis>otp</emphasis> are used only once and then forgotten, 86 i.e., wpa_supplicant will ask frontend for a new value for every use. 87 This can be used to implement one-time-password lists and generic token 88 card -based authentication.</para> 89 90 <para>Example request for password and a matching reply:</para> 91 92 <blockquote><programlisting> 93 CTRL-REQ-PASSWORD-1:Password needed for SSID foobar 94 > password 1 mysecretpassword 95 </programlisting></blockquote> 96 97 <para>Example request for generic token card challenge-response:</para> 98 99 <blockquote><programlisting> 100 CTRL-REQ-OTP-2:Challenge 1235663 needed for SSID foobar 101 > otp 2 9876 102 </programlisting></blockquote> 103 104 </refsect1> 105 <refsect1> 106 <title>Command Arguments</title> 107 <variablelist> 108 <varlistentry> 109 <term>-p path</term> 110 111 <listitem><para>Change the path where control sockets should 112 be found.</para></listitem> 113 </varlistentry> 114 115 <varlistentry> 116 <term>-g control socket path</term> 117 118 <listitem><para>Connect to the global control socket at the 119 indicated path rather than an interface-specific control 120 socket.</para></listitem> 121 </varlistentry> 122 123 <varlistentry> 124 <term>-i ifname</term> 125 126 <listitem><para>Specify the interface that is being 127 configured.
