6 # Note: This attribute can be overridden by the values supplied with the '-i'
7 # command line parameter.
10 # In case of atheros and nl80211 driver interfaces, an additional
11 # configuration parameter, bridge, may be used to notify hostapd if the
12 # interface is included in a bridge. This parameter is not used with Host AP
13 # driver. If the bridge parameter is not set, the drivers will automatically
14 # figure out the bridge interface (assuming sysfs is enabled and mounted to
15 # /sys) and this parameter may not be needed.
17 # For nl80211, this parameter can be used to request the AP interface to be
18 # added to the bridge automatically (brctl may refuse to do this before hostapd
19 # has been started to change the interface mode). If needed, the bridge
20 # interface is also created.

59 # will create this directory and a UNIX domain socket for listening to requests
60 # from external programs (CLI/GUI, etc.) for status information and
61 # configuration. The socket file will be named based on the interface name, so
62 # multiple hostapd processes/interfaces can be run at the same time if more
63 # than one interface is used.

68 # Access control for the control interface can be configured by setting the
69 # directory to allow only members of a group to use sockets. This way, it is
70 # possible to run hostapd as root (since it needs to change network
71 # configuration and open raw sockets) and still allow GUI/CLI components to be
72 # run as non-root users. However, since the control interface can be used to
73 # change the network configuration, this access needs to be protected in many
74 # cases. By default, hostapd is configured to use gid 0 (root). If you
75 # want to allow non-root users to use the contron interface, add a new group
76 # and change this value to match with that group. Add users that should have

170 # uniquely identify channels across different bands, including the 6 GHz band.
173 # ACS tuning - Automatic Channel Selection
174 # See: http://wireless.kernel.org/en/users/Documentation/acs
176 # You can customize the ACS survey algorithm with following variables:
178 # acs_num_scans requirement is 1..100 - number of scans to be performed that
179 # are used to trigger survey data gathering of an underlying device driver.
180 # Scans are passive and typically take a little over 100ms (depending on the
181 # driver) on each available channel for given hw_mode. Increasing this value
182 # means sacrificing startup time and gathering more data wrt channel
183 # interference that may help choosing a better channel. This can also help fine
184 # tune the ACS scan time in case a driver has different scan dwell times.
186 # acs_chan_bias is a space-separated list of <channel>:<bias> pairs. It can be
187 # used to increase (or decrease) the likelihood of a specific channel to be
188 # selected by the ACS algorithm. The total interference factor for each channel
189 # gets multiplied by the specified bias value before finding the channel with
190 # the lowest value. In other words, values between 0.0 and 1.0 can be used to
191 # make a channel more likely to be picked while values larger than 1.0 make the
192 # specified channel less likely to be picked. This can be used, e.g., to prefer
193 # the commonly used 2.4 GHz band channels 1, 6, and 11 (which is the default
194 # behavior on 2.4 GHz band if no acs_chan_bias parameter is specified).

1060 # This option allows hostapd to match every individual field in the right order
1061 # against the DN of the subject in the client certificate.
1063 # For example, check_cert_subject=C=US/O=XX/OU=ABC/OU=XYZ/CN=1234 will check
1064 # every individual DN field of the subject in the client certificate. If OU=XYZ
1065 # comes first in terms of the order in the client certificate (DN field of
1066 # client certificate C=US/O=XX/OU=XYZ/OU=ABC/CN=1234), hostapd will reject the
1067 # client because the order of 'OU' is not matching the specified string in
1068 # check_cert_subject.
1070 # This option also allows '*' as a wildcard. This option has some limitation.
1071 # It can only be used as per the following example.
1073 # For example, check_cert_subject=C=US/O=XX/OU=Production* and we have two
1074 # clients and DN of the subject in the first client certificate is
1075 # (C=US/O=XX/OU=Production Unit) and DN of the subject in the second client is
1076 # (C=US/O=XX/OU=Production Factory). In this case, hostapd will allow both
1077 # clients because the value of 'OU' field in both client certificates matches
1078 # 'OU' value in 'check_cert_subject' up to 'wildcard'.
1080 # * (Allow all clients, e.g., check_cert_subject=*)
1081 #check_cert_subject=string
1083 # TLS Session Lifetime in seconds

2093 # WPS capability discovery workaround for PBC with Windows 7
2094 # Windows 7 uses incorrect way of figuring out AP's WPS capabilities by acting
2095 # as a Registrar and using M1 from the AP. The config methods attribute in that
2096 # message is supposed to indicate only the configuration method supported by
2097 # the AP in Enrollee role, i.e., to add an external Registrar. For that case,
2098 # PBC shall not be used and as such, the PushButton config method is removed
2099 # from M1 by default. If pbc_in_m1=1 is included in the configuration file,
2100 # the PushButton config method is left in M1 (if included in config_methods
2101 # parameter) to allow Windows 7 to use PBC instead of PIN (e.g., from a label
2105 # Static access point PIN for initial configuration and adding Registrars
2106 # If not set, hostapd will not allow external WPS Registrars to control the
2107 # access point. The AP PIN can also be set at runtime with hostapd_cli
2108 # wps_ap_pin command. Use of temporary (enabled by user action) and random

2595 ##### Multiband Operation (MBO) ###############################################
2598 # 0 = disabled (default)
2602 # Cellular data connection preference
2603 # 0 = Excluded - AP does not want STA to use the cellular data connection
2604 # 1 = AP prefers the STA not to use cellular data connection
2605 # 255 = AP prefers the STA to use cellular data connection
2606 #mbo_cell_data_conn_pref=1
2608 ##### Optimized Connectivity Experience (OCE) #################################
2610 # Enable OCE specific features (bitmap)
2612 # Set BIT(1) (= 2) to enable OCE in STA-CFON mode
2613 # Set BIT(2) (= 4) to enable OCE in AP mode

2632 ##### Fast Session Transfer (FST) support #####################################
2634 # The options in this section are only available when the build configuration
2635 # option CONFIG_FST is set while compiling hostapd. They allow this interface
2636 # to be a part of FST setup.
2638 # FST is the transfer of a session from a channel to another channel, in the
2639 # same or different frequency bands.
2641 # For detals, see IEEE Std 802.11ad-2012.
2643 # Identifier of an FST Group the interface belongs to.
2646 # Interface priority within the FST Group.
2647 # Announcing a higher priority for an interface means declaring it more
2648 # preferable for FST switch.
2649 # fst_priority is in 1..255 range with 1 being the lowest priority.
2652 # Default LLT value for this interface in milliseconds. The value used in case
2653 # no value provided during session setup. Default is 50 ms.
2654 # fst_llt is in 1..4294967 range (due to spec limitation, see 10.32.2.2
2655 # Transitioning between states).
2658 ##### Radio measurements / location ###########################################
2660 # The content of a LCI measurement subelement
2661 #lci=<Hexdump of binary data of the LCI report>
2663 # The content of a location civic measurement subelement
2664 #civic=<Hexdump of binary data of the location civic report>
2666 # Enable neighbor report via radio measurements
2667 #rrm_neighbor_report=1

2670 #rrm_beacon_report=1
2672 # Publish fine timing measurement (FTM) responder functionality
2673 # This parameter only controls publishing via Extended Capabilities element.
2674 # Actual functionality is managed outside hostapd.
2677 # Publish fine timing measurement (FTM) initiator functionality
2678 # This parameter only controls publishing via Extended Capabilities element.
2679 # Actual functionality is managed outside hostapd.
2682 # Stationary AP config indicates that the AP doesn't move hence location data
2683 # can be considered as always up to date. If configured, LCI data will be sent
2684 # as a radio measurement even if the request doesn't contain a max age element
2685 # that allows sending of such data. Default: 0.
2688 ##### Airtime policy configuration ###########################################
2690 # Set the airtime policy operating mode:
2691 # 0 = disabled (default)
2693 # 2 = per-BSS dynamic config
2694 # 3 = per-BSS limit mode
2697 # Interval (in milliseconds) to poll the kernel for updated station activity in
2698 # dynamic and limit modes
2699 #airtime_update_interval=200
2701 # Static configuration of station weights (when airtime_mode=1). Kernel default
2702 # weight is 256; set higher for larger airtime share, lower for smaller share.
2703 # Each entry is a MAC address followed by a weight.
2704 #airtime_sta_weight=02:01:02:03:04:05 256
2705 #airtime_sta_weight=02:01:02:03:04:06 512
2707 # Per-BSS airtime weight. In multi-BSS mode, set for each BSS and hostapd will
2708 # configure station weights to enforce the correct ratio between BSS weights
2709 # depending on the number of active stations. The *ratios* between different
2710 # BSSes is what's important, not the absolute numbers.
2711 # Must be set for all BSSes if airtime_mode=2 or 3, has no effect otherwise.
2712 #airtime_bss_weight=1
2714 # Whether the current BSS should be limited (when airtime_mode=3).
2716 # If set, the BSS weight ratio will be applied in the case where the current BSS
2717 # would exceed the share defined by the BSS weight ratio. E.g., if two BSSes are
2718 # set to the same weights, and one is set to limited, the limited BSS will get
2719 # no more than half the available airtime, but if the non-limited BSS has more
2720 # stations active, that *will* be allowed to exceed its half of the available
2722 #airtime_bss_limit=1
2724 ##### EDMG support ############################################################
2726 # Enable EDMG capability for AP mode in the 60 GHz band. Default value is false.
2727 # To configure channel bonding for an EDMG AP use edmg_channel below.
2728 # If enable_edmg is set and edmg_channel is not set, EDMG CB1 will be
2732 # Configure channel bonding for AP mode in the 60 GHz band.
2733 # This parameter is relevant only if enable_edmg is set.
2734 # Default value is 0 (no channel bonding).
2737 ##### TESTING OPTIONS #########################################################
2739 # The options in this section are only available when the build configuration
2740 # option CONFIG_TESTING_OPTIONS is set while compiling hostapd. They allow
2741 # testing some scenarios that are otherwise difficult to reproduce.
2743 # Ignore probe requests sent to hostapd with the given probability, must be a
2744 # floating point number in the range [0, 1).
2745 #ignore_probe_probability=0.0
2747 # Ignore authentication frames with the given probability
2748 #ignore_auth_probability=0.0
2750 # Ignore association requests with the given probability
2751 #ignore_assoc_probability=0.0
2753 # Ignore reassociation requests with the given probability
2754 #ignore_reassoc_probability=0.0
2756 # Corrupt Key MIC in GTK rekey EAPOL-Key frames with the given probability
2757 #corrupt_gtk_rekey_mic_probability=0.0
2759 # Include only ECSA IE without CSA IE where possible
2760 # (channel switch operating class is needed)
2763 ##### Multiple BSSID support ##################################################
2765 # Above configuration is using the default interface (wlan#, or multi-SSID VLAN
2766 # interfaces). Other BSSIDs can be added by using separator 'bss' with
2767 # default interface name to be allocated for the data packets of the new BSS.
2769 # hostapd will generate BSSID mask based on the BSSIDs that are
2770 # configured. hostapd will verify that dev_addr & MASK == dev_addr. If this is
2771 # not the case, the MAC address of the radio must be changed before starting
2772 # hostapd (ifconfig wlan0 hw ether <MAC addr>). If a BSSID is configured for
2773 # every secondary BSS, this limitation is not applied at hostapd and other
2774 # masks may be used if the driver supports them (e.g., swap the locally
2777 # BSSIDs are assigned in order to each BSS, unless an explicit BSSID is
2778 # specified using the 'bssid' parameter.
2779 # If an explicit BSSID is specified, it must be chosen such that it:
2780 # - results in a valid MASK that covers it and the dev_addr
2781 # - is not the same as the MAC address of the radio
2782 # - is not the same as any other explicitly specified BSSID
2784 # Alternatively, the 'use_driver_iface_addr' parameter can be used to request
2785 # hostapd to use the driver auto-generated interface address (e.g., to use the
2786 # exact MAC addresses allocated to the device).
2788 # Not all drivers support multiple BSSes. The exact mechanism for determining
2789 # the driver capabilities is driver specific. With the current (i.e., a recent
2790 # kernel) drivers using nl80211, this information can be checked with "iw list"
2791 # (search for "valid interface combinations").
2793 # Please note that hostapd uses some of the values configured for the first BSS
2794 # as the defaults for the following BSSes. However, it is recommended that all
2795 # BSSes include explicit configuration of all relevant configuration items.
2799 # most of the above items can be used here (apart from radio interface specific
2800 # items, like channel)
