Are addresses necessary for Pi-hole to be ntp server

[ETA_2024]

Is it necessary to provide an ntp.ipv4.address and ntp.ipv6.address for Pi-hole to provide ntp services to other devices?

If they belong to these switches :

Upgrading pihole from v5 to v6 causes NTP error

Thank you for the feedback. I know that the lxc is using the time from the host machine. I changed this settings in /etc/pihole/pihole.toml and the error is gone. If someone have the same error. [ntp.ipv4] # Should FTL act as network time protocol (NTP) server (IPv4)? active = false [ntp.ipv6] # Should FTL act as network time protocol (NTP) server (IPv6)? active = false [ntp.sync] # Should FTL try to synchronize the system time with an upstream NTP server? activ…

Then YES, you need to provide them to those Settings

What if your running PI-hole on a machine (not in a container)?

[nero355]

The same applies I guess ?!

Please describe a bit more what you are doing exactly ??

Please describe a bit more what you are doing exactly ?

`ntp.ipv4.active` enabled                 `ntp.ipv4.address` undefined
`ntp.ipv6.active` enabled                 `ntp.ipv6.address` undefined
`ntp.sync.active` enabled                 `ntp.sync.server` au.pool.ntp.org
`ntp.sync.interval` 3600                  `ntp.sync.count` 8
`ntp.sync.rtc.set` not enabled            `ntp.sync.rtc.device` undefined
`ntp.sync.rtc.utc` enabled

Aim: Pi-hole to act as an NTP server for both IPv4 and IPv6 on local network.

If your leave it blank it will listen on all addresses. From the pihole you can run sudo ss -tupln |grep 123 and see if its actively listening ( 123 is the port for ntp ).

Is this output correct? Also, should it be listening for tcp requests as well?

[CallMeCurious]

That is correct and no, NTP is UDP only.

Thank you CallMeCurious.

Finally someone could answer my original question, in that addresses are not necessary for ntp to work (which make sense).
