overriding ntp server in camera
Opened this issue · 2 comments
So i'm getting tired of not having the correct time on my cameras that i block from reaching the internet.
I've figured out thanks to another post here that it seems to use ntp1.dlink.com to set the time so i tried rewriting that to my local ntp server via pfsense but no dice.
Should be a no brainer as i need to do this with other cameras, here is a pic on the pfsense config.
I'm i missing something here, maybe these cameras use sntp or something else i'm not taking into account ?
After ~1h of logs it seems like it only tries to contact these on port 443:

Out of interest I checked and the IPs my device requested were different. So I turned on Query Logging in the advanced section of the Unbound configuration on my firewall.
My device is querying mp-tw-dcdda.auto.mydlink.com which resolves to the IPs that I can see it trying to access. My firmware does come from the Taiwanese D-LINK site so maybe that explains the difference.
I also detected occasional attempts to access 13.35.218.92:80
Though like your device, nothing that looks like NTP. The LED light changes to reflect a lack of connectivity so I suppose it's possible that it doesn't try to run ntp if it thinks it doesn't have internet access.
