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.
