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

14# figure out the bridge interface (assuming sysfs is enabled and mounted to
15# /sys) and this parameter may not be needed.
16#
17# For nl80211, this parameter can be used to request the AP interface to be

73# run as non-root users. However, since the control interface can be used to
74# change the network configuration, this access needs to be protected in many
75# cases. By default, hostapd is configured to use gid 0 (root). If you

166
167# ACS tuning - Automatic Channel Selection
168# See: http://wireless.kernel.org/en/users/Documentation/acs
169#
170# You can customize the ACS survey algorithm with following variables:
171#
172# acs_num_scans requirement is 1..100 - number of scans to be performed that
173# are used to trigger survey data gathering of an underlying device driver.
174# Scans are passive and typically take a little over 100ms (depending on the
175# driver) on each available channel for given hw_mode. Increasing this value
176# means sacrificing startup time and gathering more data wrt channel
177# interference that may help choosing a better channel. This can also help fine
178# tune the ACS scan time in case a driver has different scan dwell times.
179#
180# acs_chan_bias is a space-separated list of <channel>:<bias> pairs. It can be
181# used to increase (or decrease) the likelihood of a specific channel to be
182# selected by the ACS algorithm. The total interference factor for each channel
183# gets multiplied by the specified bias value before finding the channel with
184# the lowest value. In other words, values between 0.0 and 1.0 can be used to
185# make a channel more likely to be picked while values larger than 1.0 make the
186# specified channel less likely to be picked. This can be used, e.g., to prefer
187# the commonly used 2.4 GHz band channels 1, 6, and 11 (which is the default
188# behavior on 2.4 GHz band if no acs_chan_bias parameter is specified).
189#

1355# Workaround for key reinstallation attacks
1356#
1357# This parameter can be used to disable retransmission of EAPOL-Key frames that
1358# are used to install keys (EAPOL-Key message 3/4 and group message 1/2). This
1359# is similar to setting wpa_group_update_count=1 and
1360# wpa_pairwise_update_count=1, but with no impact to message 1/4 and with
1361# extended timeout on the response to avoid causing issues with stations that
1362# may use aggressive power saving have very long time in replying to the
1363# EAPOL-Key messages.
1364#
1365# This option can be used to work around key reinstallation attacks on the
1366# station (supplicant) side in cases those station devices cannot be updated
1367# for some reason. By removing the retransmissions the attacker cannot cause
1368# key reinstallation with a delayed frame transmission. This is related to the
1369# station side vulnerabilities CVE-2017-13077, CVE-2017-13078, CVE-2017-13079,
1370# CVE-2017-13080, and CVE-2017-13081.

1455# is used to select which password to use. Setting sae_password to an empty

1790# WPS capability discovery workaround for PBC with Windows 7
1791# Windows 7 uses incorrect way of figuring out AP's WPS capabilities by acting
1792# as a Registrar and using M1 from the AP. The config methods attribute in that
1793# message is supposed to indicate only the configuration method supported by
1794# the AP in Enrollee role, i.e., to add an external Registrar. For that case,
1795# PBC shall not be used and as such, the PushButton config method is removed
1796# from M1 by default. If pbc_in_m1=1 is included in the configuration file,
1797# the PushButton config method is left in M1 (if included in config_methods
1798# parameter) to allow Windows 7 to use PBC instead of PIN (e.g., from a label

1805# wps_ap_pin command. Use of temporary (enabled by user action) and random

2358##### Multiple BSSID support ##################################################
2359#
2360# Above configuration is using the default interface (wlan#, or multi-SSID VLAN
2361# interfaces). Other BSSIDs can be added by using separator 'bss' with
2362# default interface name to be allocated for the data packets of the new BSS.
2363#
2364# hostapd will generate BSSID mask based on the BSSIDs that are
2365# configured. hostapd will verify that dev_addr & MASK == dev_addr. If this is
2366# not the case, the MAC address of the radio must be changed before starting
2367# hostapd (ifconfig wlan0 hw ether <MAC addr>). If a BSSID is configured for
2368# every secondary BSS, this limitation is not applied at hostapd and other
2369# masks may be used if the driver supports them (e.g., swap the locally
2370# administered bit)
2371#
2372# BSSIDs are assigned in order to each BSS, unless an explicit BSSID is
2373# specified using the 'bssid' parameter.
2374# If an explicit BSSID is specified, it must be chosen such that it:
2375# - results in a valid MASK that covers it and the dev_addr
2376# - is not the same as the MAC address of the radio
2377# - is not the same as any other explicitly specified BSSID
2378#
2379# Alternatively, the 'use_driver_iface_addr' parameter can be used to request
2380# hostapd to use the driver auto-generated interface address (e.g., to use the
2381# exact MAC addresses allocated to the device).
2382#
2383# Not all drivers support multiple BSSes. The exact mechanism for determining
2384# the driver capabilities is driver specific. With the current (i.e., a recent
2385# kernel) drivers using nl80211, this information can be checked with "iw list"
2386# (search for "valid interface combinations").
2387#
2388# Please note that hostapd uses some of the values configured for the first BSS
2389# as the defaults for the following BSSes. However, it is recommended that all
2390# BSSes include explicit configuration of all relevant configuration items.
2391#
