I am seeing a lot of DNS traffic from my RoPieee devices. It seems every 12 secs the Ropieee is doing a NTP sync, by trying to contact 0.pool.ntp.org - 3.pool.ntp.org every 12 secs. That seems excessive.
I have a local DNS server and NTP server, so I am redirecting the DNS queries to my local NTP server.
For public NTP servers, the minpoll is suggested to be no less than 64secs.
So I have two suggestions or questions:
can we add a config for the used NTP servers/pool ?
can we add a config for the polling frequency, or at least ease up the current polling frequency ?
(one assumption is the dns query every 12secs is indicative for a ntp sync every 12secs)
Well, in general I don’t mind ‘overkill’, as long as it happens automagically and is not something the user needs to think of. So if we can support things like this, without exposing it to the user (like with a setting for example) then it could be interesting.
Take for example the TZ thingie: for those that run RoPieee with a display there’s an option to set the timezone. If we can automate this because it is provided via DHCP … that might be cool.
