What NTP Time Servers URLs does the Nano-SD use for Time Synchronization

[rzelle-K1TTC]

I need to know what NTP Time server or servers the Nano-SD is programmed to use and is there a way to re-program it to use an internal NTP Server

Hi Boris,

I should have addressed my question to you regarding what NTP server is the Nano-SD programmed to use. For security reason my network uses a local Satellite based NTP server. If I know the Time Server urls the Nano is using I can resolve them locally on my DNS servers.

Thanks,

..Ron

Thanks Mark, I will see if I can determine if the Nano is using those ntp pools

Hi Mark,

Where did you find the file with the config info and what was its name. I've been looking for a file with that info on my Nano and can't find anything that has NTP info in it?

Hi Ron,

If you SSH to the Nano SD and go to the /etc/config directory there is a file called system and in this file I found the NTP server setting on my PRO2 as below

Hope its helps you

Mark,

Thanks that's where it is on the Nano so I verified it was using the same urls. I had configured my DNS servers with those urls to point to my local ntp satellite receiver and it also picked up the Purple Air as a NTP client. A win win ..

Thanks,
.. Ron

Anybody know the interval the NTP Time Servers are checked? Or is the time only sync'd at boot?

How difficult to built a user definable NTP Time server interface into the GUI? Some Proxy servers appear to block outside NTP links?

Hi,

This may help

On the Openwrt documentation pages it indicates the default is 600s so if it’s not been changed it’s likely to be that.
