Flood of DNS requests to NTP server
Hi,
Since the last firmware update, I can see a huge increase in DNS requests coming from the Deco units (M9 plus).
In fact, every second (!) on average there are multiple requests to eu.pool.ntp.org. My logs are being flooded by this.
I know this is an NTP server used for time synchronisation, but it is not normal to do this multiple times per second. More like once every hour.
A small excerpt from my Pi-Hole logs:
Jun 3 14:27:52 dnsmasq[546]: query[AAAA] eu.pool.ntp.org from 192.168.1.xxx Jun 3 14:27:52 dnsmasq[546]: cached eu.pool.ntp.org is NXDOMAIN Jun 3 14:27:52 dnsmasq[546]: query[A] eu.pool.ntp.org from 192.168.1.xxx Jun 3 14:27:52 dnsmasq[546]: cached eu.pool.ntp.org is NXDOMAIN Jun 3 14:27:53 dnsmasq[546]: query[AAAA] eu.pool.ntp.org from 192.168.1.xxx Jun 3 14:27:53 dnsmasq[546]: cached eu.pool.ntp.org is NXDOMAIN Jun 3 14:27:53 dnsmasq[546]: query[A] eu.pool.ntp.org from 192.168.1.xxx Jun 3 14:27:53 dnsmasq[546]: cached eu.pool.ntp.org is NXDOMAIN Jun 3 14:27:53 dnsmasq[546]: query[AAAA] eu.pool.ntp.org from 192.168.1.xxx Jun 3 14:27:53 dnsmasq[546]: cached eu.pool.ntp.org is NXDOMAIN Jun 3 14:27:53 dnsmasq[546]: query[A] eu.pool.ntp.org from 192.168.1.xxx Jun 3 14:27:53 dnsmasq[546]: cached eu.pool.ntp.org is NXDOMAIN Jun 3 14:27:58 dnsmasq[546]: query[AAAA] eu.pool.ntp.org from 192.168.1.xxx Jun 3 14:27:58 dnsmasq[546]: cached eu.pool.ntp.org is NXDOMAIN Jun 3 14:27:58 dnsmasq[546]: query[A] eu.pool.ntp.org from 192.168.1.xxx Jun 3 14:27:58 dnsmasq[546]: cached eu.pool.ntp.org is NXDOMAIN Jun 3 14:27:59 dnsmasq[546]: query[AAAA] eu.pool.ntp.org from 192.168.1.xxx Jun 3 14:27:59 dnsmasq[546]: cached eu.pool.ntp.org is NXDOMAIN Jun 3 14:27:59 dnsmasq[546]: query[A] eu.pool.ntp.org from 192.168.1.xxx Jun 3 14:27:59 dnsmasq[546]: cached eu.pool.ntp.org is NXDOMAIN Jun 3 14:27:59 dnsmasq[546]: query[AAAA] eu.pool.ntp.org from 192.168.1.xxx Jun 3 14:27:59 dnsmasq[546]: cached eu.pool.ntp.org is NXDOMAIN Jun 3 14:27:59 dnsmasq[546]: query[A] eu.pool.ntp.org from 192.168.1.xxx Jun 3 14:27:59 dnsmasq[546]: cached eu.pool.ntp.org is NXDOMAIN
I have three Deco units installed and they are all making these silly requests.
Does anyone else experience the same?
