This parameter is not used with Host AP 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 17# has been started to change the interface mode).

If this is specified, hostapd 58# will create this directory and a UNIX domain socket for listening to requests 59# from external programs (CLI/GUI, etc.) for status information and 60# configuration. The socket file will be named based on the interface name, so 61# multiple hostapd processes/interfaces can be run at the same time if more 62# than one interface is used. 63# /var/run/hostapd is the recommended directory for sockets and by default, 64# hostapd_cli will use it when trying to connect with hostapd. 65ctrl_interface=/var/run/hostapd 66 67# Access control for the control interface can be configured by setting the 68# directory to allow only members of a group to use sockets. This way, it is 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.

Other BSSIDs can be added by using separator 'bss' with 1548# default interface name to be allocated for the data packets of the new BSS. 1549# 1550# hostapd will generate BSSID mask based on the BSSIDs that are 1551# configured. hostapd will verify that dev_addr & MASK == dev_addr. If this is 1552# not the case, the MAC address of the radio must be changed before starting 1553# hostapd (ifconfig wlan0 hw ether <MAC addr>). If a BSSID is configured for 1554# every secondary BSS, this limitation is not applied at hostapd and other 1555# masks may be used if the driver supports them (e.g., swap the locally 1556# administered bit) 1557# 1558# BSSIDs are assigned in order to each BSS, unless an explicit BSSID is 1559# specified using the 'bssid' parameter. 1560# If an explicit BSSID is specified, it must be chosen such that it: 1561# - results in a valid MASK that covers it and the dev_addr 1562# - is not the same as the MAC address of the radio 1563# - is not the same as any other explicitly specified BSSID 1564# 1565# Please note that hostapd uses some of the values configured for the first BSS 1566# as the defaults for the following BSSes.
