This is for centos 7 that has chronyd 2.1.1 I am looking into how to use chronyd as my local ntp server. On my old servers with ntpd I had local access control lines like: restrict 192.168.128.0 mask 255.255.255.0 nomodify notrap But in looking for documentation on chronyd I did not find anything on this at: https://chrony.tuxfamily.org/doc/2.1/manual.html In the actual /etc/chronyd.conf there is the sample line: # Allow NTP client access from local network. #allow 192.168/16 Does this allow only allow queries? Does chronyd support the 'restrict' option? thank you
