There is a src rpm available for Centos7
wget -c https://www.urlfilterdb.com/files/downloads/ufdbGuard-1.32.4.src.rpm
but there is an old init script used not a systemd service. I was able to compile the src rpm that’s no problem.
But as i know in Centos 7 systemd is the new standard…
For hostapd will check if I can compile from src rpm…
