No conf or management, means that you can't fix issues
that they never thought of, several years into the products life?
e.g. The recent attention to SSL & noquery, abuseable features?
You can't do "no conf file fiddling, no management" and keyed;
unless they are all keyed the same,
or keyed to a serial number (or something).
I'd prefer keyed manycast over multicast.
keys ".../etc/ntp.keys" # e.g. contains: 123 M YOUR_MD5_KEY
manycastclient 126.96.36.199 key 123 preempt
How do you do LAN restrict statements without conf or management?
or do you need to SSH into it and can't get a query from the LAN?
restrict -4 default limited kod nomodify notrap nopeer noquery
restrict -6 default limited kod nomodify notrap nopeer noquery
restrict 188.8.131.52 mask 255.255.255.255 nomodify
restrict 192.168.0.0 mask 255.255.255.0 nomodify
restrict source nomodify
