NAME
====
iwd.ap - Access point provisioning files

SYNOPSIS
========

Description of access point provisioning files.

DESCRIPTION
===========

An access point provisioning file defines the configuration of an IWD access
point. These files live in *$STATE_DIRECTORY*/ap (/var/lib/iwd/ap by default).
They are read when the `net.connman.iwd.AccessPoint.StartProfile(ssid)` DBus
method is used.

FILE FORMAT
===========

See *iwd.network* for details on the settings file syntax.

SETTINGS
========

The settings are split into several categories.  Each category has a group
associated with it and is described in the corresponding table below.

General Settings
----------------

The group ``[General]`` contains general AP configuration.

.. list-table::
   :header-rows: 0
   :stub-columns: 0
   :widths: 20 80
   :align: left

   * - Channel
     - Channel number

       Optional channel number for the access point to operate on.  Only the
       2.4GHz-band channels are currently allowed.

Network Authentication Settings
-------------------------------

The group ``[Security]`` contains settings for Wi-Fi security and authentication
configuration.

.. list-table::
   :header-rows: 0
   :stub-columns: 0
   :widths: 20 80
   :align: left

   * - Passphrase
     - 8..63 character string

       WPA-PSK Passphrase to be used with this access point.  At least one of
       *Passphrase*, *PreSharedKey* must be present.

   * - PreSharedKey
     - 64-character hex-string

       Processed passphrase for this network in the form of a hex-encoded
       32-byte pre-shared key.  Either this or *Passphrase* must be present.

IPv4 Network Configuration
--------------------------

The group ``[IPv4]`` contains settings for IWD's built-in DHCP server.  All
settings are optional.  They're used if network configuration was enabled as
described in ``iwd.config(5)``.  Omitting the ``[IPv4]`` group disables
network configuration for this access point so if an all-defaults DHCP setup
is desired, the group header line must still be present:

.. code-block::

   # Enable network configuration
   [IPv4]

   [other groups follow]

.. list-table::
   :header-rows: 0
   :stub-columns: 0
   :widths: 20 80

   * - Address
     - Local IP address

       Optional local address pool for the access point and the DHCP server.
       If provided this addresss will be set on the AP interface and any other
       DHCP server options will be derived from it, unless they are overridden
       by other settings below.  If *Address* is not provided and no IP
       address is set on the interface prior to calling `StartProfile`,  the IP
       pool defined by the global ``[General].APRanges`` setting will be used.

   * - Gateway
     - IP Address of gateway

       IP address of the gateway to be advertised by DHCP. This will fall back
       to the local IP address if not provided.

   * - Netmask
     - Local netmask of the AP

       This will be generated from ``[IPv4].Address`` if not provided.

   * - DNSList
     - List of DNS servers as a comma-separated IP address list

       A list of DNS servers which will be advertised by the DHCP server. If
       not provided no DNS servers will be sent by the DHCP server.

   * - LeaseTime
     - Time limit for DHCP leases in seconds

       Override the default lease time.

   * - IPRange
     - Range of IPs given as two addresses separated by a comma

       From and to addresses of the range assigned to clients through DHCP.
       If not provided the range from local address + 1 to .254 will be used.

Wi-Fi Simple Configuration
--------------------------

The group ``[WSC]`` fine-tunes some Wi-Fi Simple Configuration local parameters
(formerly known as WPS, Wi-Fi Protected Setup.)

.. list-table::
   :header-rows: 0
   :stub-columns: 0
   :widths: 20 80
   :align: left

   * - DeviceName
     - 1..32-character string

       Optional Device Name string for the AP to advertise as.  Defaults to
       the SSID.

   * - PrimaryDeviceType
     - Subcategory string or a 64-bit integer

       Optional Primary Device Type for the AP to advertise as.  Defaults to
       PC computer.  Can be specified as a lower-case WSC v2.0.5 subcategory
       string or a 64-bit integer encoding, from MSB to LSB: the 16-bit
       category ID, the 24-bit OUI, the 8-bit OUI type and the 16-bit
       subcategory ID.

   * - AuthorizedMACs
     - Comma-separated MAC address list

       Optional list of Authorized MAC addresses for the WSC registrar to
       check on association.  Each address is specified in the
       colon-hexadecimal notation.  Defaults to no MAC-based checks.
