I am using hostapd to turn my pi into a wireless access point, I want to implement a blacklist to block certain device from connecting to the network.
I should be able to do this at a MAC address level by including the following lines in the hostapd.conf file - however when I include it the configuration file won't build correctly and the pi no longer acts as an AP.
macaddr_acl=0
deny_mac_file=/etc/hostapd/hostapd.deny
Any guidance as to why this is causing the .conf file to break, or an alternative way to block hosts from connecting to the AP would be much appreciated.
