ReadyNAS Timesync - thousands of queries per day to timesync server
Hi,
having ReadyNAS 312 with the latest firmware 6.10.3 i am facing the following problem.
Timesync settings are set to default and timesync is on. I think that NAS is doing timesync correctly, because the time is accurate.
But as i can see, it generates connection to time-a.netgear.com and time-e.netgear.com every 5 seconds during whole day/night.
So it creates around 36000 connections/requests per a single day (attached image, the green line) to my own custom DNS server.
I am using Google DNS and also tried Open DNS as alternative. Also disabled DNS filter just for test it. No difference.
When i try ping both timesync servers, hostnames are translated into ip addresses correctly, but ping fails. It runs on Windows so maybe it is using some default port for HTTP and not for timesyncing.
Is there a way how to fix it or how to manually decrease timesync frequency? I can use SSH and i know basic linux commands.
I think that earlier there were not as many requests as is DNS server having now.

The NAS uses connman for NTP, and AFAICT there are no settings in connman to control the polling rate. Though it looks like my own system is querying every 17 minutes.
You might want to try a different time server and see if that makes a difference. 0.pool.ntp.org; 1.pool.ntp.org generally work well, though you can also refine the geography if you like (0.us.pool.ntp.org for instance). https://www.ntppool.org/en/use.html
Hi,
first thank you for your reply.
I have tried your settings with the following NTP servers 0.pool.ntp.org 1.pool.ntp.org but it is same as with default NTP servers.
ReadyNAS makes 2 connections every 5 seconds which results 2*12*60*24 = around 34000 connections to NTP servers per day.
(i am measuring requests to DNS server which is located inside my local network)
I can observe the only difference, when only 1 NTP server instead of 2 NTP servers is inputted.
Then 2 connections to NTP server are made every 10 seconds which results around 17k daily.
And yes, as I have double checked, time is synchronized correctly with default or ntp.org NTP servers as well as with time.windows.com
So there is no option how to influent the number of connections made, I mean the frequency? I know basic and some more linux commands which can be done via SSH. I would really like setting frequency at least to 30 seconds or 1 minute or so.
Also I have been checking if there is some custom application for ReadyNAS like running own NTP server with own custom settings.
But I have found nothing.
To be precise. Delay between two NTP server requests is 5 seconds. Delay after the last request for NTP server (tested with 1, 2 or 3 NTP servers addresses) is 10 seconds. I would like to change it somehow, to have delay of my own choice. Any ideas?
I have also searched all connman files in my ReadyNAS via SSH, checked their content and there is really no place to set delay manually.
Would it be possible to disable timesync feature in GUI and just add a cron job? But i dont know how to call timesync procedure manually.
