8# In case of madwifi, atheros, and nl80211 driver interfaces, an additional
9# configuration parameter, bridge, may be used to notify hostapd if the

11# driver. If the bridge parameter is not set, the drivers will automatically
12# figure out the bridge interface (assuming sysfs is enabled and mounted to
13# /sys) and this parameter may not be needed.
14#
15# For nl80211, this parameter can be used to request the AP interface to be
16# added to the bridge automatically (brctl may refuse to do this before hostapd

61# multiple hostapd processes/interfaces can be run at the same time if more

67# Access control for the control interface can be configured by setting the

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

980##### Multiple BSSID support ##################################################
981#
982# Above configuration is using the default interface (wlan#, or multi-SSID VLAN
983# interfaces). Other BSSIDs can be added by using separator 'bss' with
984# default interface name to be allocated for the data packets of the new BSS.
985#
986# hostapd will generate BSSID mask based on the BSSIDs that are
987# configured. hostapd will verify that dev_addr & MASK == dev_addr. If this is
988# not the case, the MAC address of the radio must be changed before starting
989# hostapd (ifconfig wlan0 hw ether <MAC addr>). If a BSSID is configured for
990# every secondary BSS, this limitation is not applied at hostapd and other
991# masks may be used if the driver supports them (e.g., swap the locally
992# administered bit)
993#
994# BSSIDs are assigned in order to each BSS, unless an explicit BSSID is
995# specified using the 'bssid' parameter.
996# If an explicit BSSID is specified, it must be chosen such that it:
997# - results in a valid MASK that covers it and the dev_addr
998# - is not the same as the MAC address of the radio
999# - is not the same as any other explicitly specified BSSID
1000#
1001# Please note that hostapd uses some of the values configured for the first BSS
1002# as the defaults for the following BSSes. However, it is recommended that all
1003# BSSes include explicit configuration of all relevant configuration items.
1004#
1005#bss=wlan0_0
1006#ssid=test2
1007# most of the above items can be used here (apart from radio interface specific
1008# items, like channel)
