 # In case of madwifi, atheros, and nl80211 driver interfaces, an additional
 # configuration parameter, bridge, may be used to notify hostapd if the
 # interface is included in a bridge. This parameter is not used with Host AP
 # driver. If the bridge parameter is not set, the drivers will automatically
 # figure out the bridge interface (assuming sysfs is enabled and mounted to
 # /sys) and this parameter may not be needed.
 #
 # For nl80211, this parameter can be used to request the AP interface to be
 # added to the bridge automatically (brctl may refuse to do this before hostapd
 # has been started to change the interface mode). If needed, the bridge
 # interface is also created.

 # Interface for separate control program. If this is specified, hostapd
 # will create this directory and a UNIX domain socket for listening to requests
 # from external programs (CLI/GUI, etc.) for status information and
 # configuration. The socket file will be named based on the interface name, so
 # multiple hostapd processes/interfaces can be run at the same time if more
 # than one interface is used.
 # /var/run/hostapd is the recommended directory for sockets and by default,
 # hostapd_cli will use it when trying to connect with hostapd.
 ctrl_interface=/var/run/hostapd

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

 # Station inactivity limit

 # clear station table of old entries when the STAs move out of the
 # range.
 #
 # The station can associate again with the AP if it is still in range;
 # this inactivity poll is just used as a nicer way of verifying
 # inactivity; i.e., client will not report broken connection because

 ##### Integrated EAP server ###################################################

 # Optionally, hostapd can be configured to use an integrated EAP server
 # to process EAP authentication locally without need for an external RADIUS
 # server. This functionality can be used both as a local authentication server
 # for IEEE 802.1X/EAPOL and as a RADIUS server for other devices.

 # Use integrated EAP server instead of external RADIUS authentication
 # server. This is also needed if hostapd is configured to act as a RADIUS
 # authentication server.

 # ephemeral DH key exchange. In addition, ciphers with DSA keys always use
 # ephemeral DH keys. This can be used to achieve forward secrecy. If the file
 # is in DSA parameters format, it will be automatically converted into DH

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

 # Static access point PIN for initial configuration and adding Registrars
 # If not set, hostapd will not allow external WPS Registrars to control the
 # access point. The AP PIN can also be set at runtime with hostapd_cli
 # wps_ap_pin command. Use of temporary (enabled by user action) and random
 # AP PIN is much more secure than configuring a static AP PIN here. As such,
 # use of the ap_pin parameter is not recommended if the AP device has means for
 # displaying a random PIN.

 # Additional Credential attribute(s)
 # This option can be used to add pre-configured Credential attributes into M8
 # message when acting as a Registrar. If skip_cred_build=1, this data will also
 # be able to override the Credential attribute that would have otherwise been
 # automatically generated based on network configuration. This configuration
 # option points to an external file that much contain the WPS Credential
 # attribute(s) as binary data.

 # Credential processing

 #   1 = do not process received credentials; just pass them over ctrl_iface to

 #   2 = process received credentials internally and pass them over ctrl_iface
 #	to external program(s)
 # Note: With wps_cred_processing=1, skip_cred_build should be set to 1 and
 # extra_cred be used to provide the Credential data for Enrollees.
 #
 # wps_cred_processing=1 will disabled automatic updates of hostapd.conf file
 # both for Credential processing and for marking AP Setup Locked based on
 # validation failures of AP PIN. An external program is responsible on updating
 # the configuration appropriately in this case.
 #wps_cred_processing=0

 # AP Settings Attributes for M7
 # By default, hostapd generates the AP Settings Attributes for M7 based on the
 # current configuration. It is possible to override this by providing a file

 # NFC password token for WPS

Other BSSIDs can be added by using separator 'bss' with # default interface name to be allocated for the data packets of the new BSS. # # hostapd will generate BSSID mask based on the BSSIDs that are # configured. hostapd will verify that dev_addr & MASK == dev_addr. If this is # not the case, the MAC address of the radio must be changed before starting # hostapd (ifconfig wlan0 hw ether <MAC addr>). If a BSSID is configured for # every secondary BSS, this limitation is not applied at hostapd and other # masks may be used if the driver supports them (e.g., swap the locally # administered bit) # # BSSIDs are assigned in order to each BSS, unless an explicit BSSID is # specified using the 'bssid' parameter. # If an explicit BSSID is specified, it must be chosen such that it: # - results in a valid MASK that covers it and the dev_addr # - is not the same as the MAC address of the radio # - is not the same as any other explicitly specified BSSID # # Please note that hostapd uses some of the values configured for the first BSS # as the defaults for the following BSSes. However, it is recommended that all # BSSes include explicit configuration of all relevant configuration items. # #bss=wlan0_0 #ssid=test2 # most of the above items can be used here (apart from radio interface specific # items, like channel) #bss=wlan0_1 #bssid=00:13:10:95:fe:0b # ...
