Increasing this value # means sacrificing startup time and gathering more data wrt channel # interference that may help choosing a better channel. This can also help fine # tune the ACS scan time in case a driver has different scan dwell times. # # acs_chan_bias is a space-separated list of : pairs. It can be # used to increase (or decrease) the likelihood of a specific channel to be # selected by the ACS algorithm. The total interference factor for each channel # gets multiplied by the specified bias value before finding the channel with # the lowest value. In other words, values between 0.0 and 1.0 can be used to # make a channel more likely to be picked while values larger than 1.0 make the # specified channel less likely to be picked.

If OU=XYZ # comes first in terms of the order in the client certificate (DN field of # client certificate C=US/O=XX/OU=XYZ/OU=ABC/CN=1234), hostapd will reject the # client because the order of 'OU' is not matching the specified string in # check_cert_subject. # # This option also allows '*' as a wildcard. This option has some limitation. # It can only be used as per the following example. # # For example, check_cert_subject=C=US/O=XX/OU=Production* and we have two # clients and DN of the subject in the first client certificate is # (C=US/O=XX/OU=Production Unit) and DN of the subject in the second client is # (C=US/O=XX/OU=Production Factory).

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 ). 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 # # Alternatively, the 'use_driver_iface_addr' parameter can be used to request # hostapd to use the driver auto-generated interface address (e.g., to use the # exact MAC addresses allocated to the device). # # Not all drivers support multiple BSSes. The exact mechanism for determining # the driver capabilities is driver specific. With the current (i.e., a recent # kernel) drivers using nl80211, this information can be checked with "iw list" # (search for "valid interface combinations"). # # 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 # ...
