Can anyone shed light on how I might find out what this query is that I am seeing in the pihole logs?

 

Click to see full size

 

The device is a Dahua security camera, it does not make any other queries that I can see. I have run wireshark to check for any traffic, and there is nothing that correlates time wise. Wireshark only shows ARP, IGMP and SSDP traffic from the camera. I only have the one camera, so cannot compare devices. My Dahua NVR only shows ntp and smtp traffic on the pihole logs. 

 

I am aware of the security implications of allowing the camera access to the internet/network, and will shortly be putting it on its own vlan, but in the mean time would still like to know what it is doing.

 

Any insights would be appreciated.

This is an issue with PiHole FTL not able to read the logs quickly enough (normally due to an overloaded system in most cases). If you restart FTL or the system (/etc/init.d/pihole-FTL restart) it should re-read the logs.

I will give it a go, but I have restarted the system several times since seeing this, and it has not changed anything. I should mention that the camera is the only client that shows a domain lookup of none.

 

The pi is running at around 5% cpu usage, with only the pihole, vnc and pivpn running on it.

Restarting FTL has not fixed this.

After posting this issue on the pihole forums, it has been suggested that the camera is genuinely trying to query 'none'.
