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
76# want to allow non-root users to use the contron interface, add a new group
77# and change this value to match with that group. Add users that should have

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#

950# to process EAP authentication locally without need for an external RADIUS
951# server. This functionality can be used both as a local authentication server
952# for IEEE 802.1X/EAPOL and as a RADIUS server for other devices.
953

983# for both server certificates and/or client certificates).
984#
985# The main use case for this alternative server certificate configuration is to
986# enable both RSA and ECC public keys. The server will pick which one to use

1005# This can be done by using PEM format for CA certificate and CRL and

1034# This option allows hostapd to match every individual field in the right order
1035# against the DN of the subject in the client certificate.
1036#
1037# For example, check_cert_subject=C=US/O=XX/OU=ABC/OU=XYZ/CN=1234 will check
1038# every individual DN field of the subject in the client certificate. If OU=XYZ
1039# comes first in terms of the order in the client certificate (DN field of
1040# client certificate C=US/O=XX/OU=XYZ/OU=ABC/CN=1234), hostapd will reject the
1041# client because the order of 'OU' is not matching the specified string in
1042# check_cert_subject.
1043#
1044# This option also allows '*' as a wildcard. This option has some limitation.
1045# It can only be used as per the following example.
1046#
1047# For example, check_cert_subject=C=US/O=XX/OU=Production* and we have two
1048# clients and DN of the subject in the first client certificate is
1049# (C=US/O=XX/OU=Production Unit) and DN of the subject in the second client is
1050# (C=US/O=XX/OU=Production Factory). In this case, hostapd will allow both
1051# clients because the value of 'OU' field in both client certificates matches
1052# 'OU' value in 'check_cert_subject' up to 'wildcard'.

2641##### TESTING OPTIONS #########################################################
2642#
2643# The options in this section are only available when the build configuration
2644# option CONFIG_TESTING_OPTIONS is set while compiling hostapd. They allow
2645# testing some scenarios that are otherwise difficult to reproduce.
2646#
2647# Ignore probe requests sent to hostapd with the given probability, must be a
2648# floating point number in the range [0, 1).
2649#ignore_probe_probability=0.0

2651# Ignore authentication frames with the given probability
2652#ignore_auth_probability=0.0
2653#
2654# Ignore association requests with the given probability
2655#ignore_assoc_probability=0.0

2661#corrupt_gtk_rekey_mic_probability=0.0

2664# (channel switch operating class is needed)
2665#ecsa_ie_only=0

2667##### Multiple BSSID support ##################################################
2668#
2669# Above configuration is using the default interface (wlan#, or multi-SSID VLAN
2670# interfaces). Other BSSIDs can be added by using separator 'bss' with
2671# default interface name to be allocated for the data packets of the new BSS.
2672#
2673# hostapd will generate BSSID mask based on the BSSIDs that are
2674# configured. hostapd will verify that dev_addr & MASK == dev_addr. If this is
2675# not the case, the MAC address of the radio must be changed before starting
2676# hostapd (ifconfig wlan0 hw ether <MAC addr>). If a BSSID is configured for
2677# every secondary BSS, this limitation is not applied at hostapd and other
2678# masks may be used if the driver supports them (e.g., swap the locally
2679# administered bit)
2680#
2681# BSSIDs are assigned in order to each BSS, unless an explicit BSSID is
2682# specified using the 'bssid' parameter.
2683# If an explicit BSSID is specified, it must be chosen such that it:
2684# - results in a valid MASK that covers it and the dev_addr
2685# - is not the same as the MAC address of the radio
2686# - is not the same as any other explicitly specified BSSID
2687#
2688# Alternatively, the 'use_driver_iface_addr' parameter can be used to request
2689# hostapd to use the driver auto-generated interface address (e.g., to use the
2690# exact MAC addresses allocated to the device).
2691#
2692# Not all drivers support multiple BSSes. The exact mechanism for determining
2693# the driver capabilities is driver specific. With the current (i.e., a recent
2694# kernel) drivers using nl80211, this information can be checked with "iw list"
2695# (search for "valid interface combinations").
2696#
2697# Please note that hostapd uses some of the values configured for the first BSS
2698# as the defaults for the following BSSes. However, it is recommended that all
2699# BSSes include explicit configuration of all relevant configuration items.
2700#

2704# items, like channel)
