10# In case of atheros and nl80211 driver interfaces, an additional

14# figure out the bridge interface (assuming sysfs is enabled and mounted to

17# For nl80211, this parameter can be used to request the AP interface 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 control interface, add a new group
76# and change this value to match with that group. Add users that should have

173# ACS tuning - Automatic Channel Selection
174# See: https://wireless.wiki.kernel.org/en/users/documentation/acs
175#
176# You can customize the ACS survey algorithm with following variables:
177#
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.
185#
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).

1171#
1172# For example, check_cert_subject=C=US/O=XX/OU=ABC/OU=XYZ/CN=1234 will check

1174# comes first in terms of the order in the client certificate (DN field of

1177# check_cert_subject.
1178#
1179# This option also allows '*' as a wildcard. This option has some limitation.
1180# It can only be used as per the following example.
1181#
1182# For example, check_cert_subject=C=US/O=XX/OU=Production* and we have two

1184# (C=US/O=XX/OU=Production Unit) and DN of the subject in the second client is
1185# (C=US/O=XX/OU=Production Factory). In this case, hostapd will allow both

1887# uses the wpa_passphrase value.
1888#
1889# Each sae_password entry is added to a list of available passwords. This
1890# corresponds to the dot11RSNAConfigPasswordValueEntry. sae_password value
1891# starts with the password (dot11RSNAConfigPasswordCredential). That value can

1893# by optional password identifier (dot11RSNAConfigPasswordIdentifier). In

1895# to the specified VLAN whenever the specific SAE password entry is used.

3006##### Multiple BSSID support ##################################################
3007#
3008# Above configuration is using the default interface (wlan#, or multi-SSID VLAN
3009# interfaces). Other BSSIDs can be added by using separator 'bss' with
3010# default interface name to be allocated for the data packets of the new BSS.
3011#
3012# hostapd will generate BSSID mask based on the BSSIDs that are
3013# configured. hostapd will verify that dev_addr & MASK == dev_addr. If this is
3014# not the case, the MAC address of the radio must be changed before starting
3015# hostapd (ifconfig wlan0 hw ether <MAC addr>). If a BSSID is configured for
3016# every secondary BSS, this limitation is not applied at hostapd and other
3017# masks may be used if the driver supports them (e.g., swap the locally
3018# administered bit)
3019#
3020# BSSIDs are assigned in order to each BSS, unless an explicit BSSID is
3021# specified using the 'bssid' parameter.
3022# If an explicit BSSID is specified, it must be chosen such that it:
3023# - results in a valid MASK that covers it and the dev_addr
3024# - is not the same as the MAC address of the radio
3025# - is not the same as any other explicitly specified BSSID
3026#
3027# Alternatively, the 'use_driver_iface_addr' parameter can be used to request
3028# hostapd to use the driver auto-generated interface address (e.g., to use the
3029# exact MAC addresses allocated to the device).
3030#
3031# Not all drivers support multiple BSSes. The exact mechanism for determining
3032# the driver capabilities is driver specific. With the current (i.e., a recent
3033# kernel) drivers using nl80211, this information can be checked with "iw list"
3034# (search for "valid interface combinations").
3035#
3036# Please note that hostapd uses some of the values configured for the first BSS
3037# as the defaults for the following BSSes. However, it is recommended that all
3038# BSSes include explicit configuration of all relevant configuration items.
