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.

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).
