KEA DHCP missing "Register DHCP leases in DNS Resolver..."
-
So based on the 2.8.0 release notes it sounds to me like KEA should now support resolving DNS names, right? Seems to me like that's what it's saying, but I'm not an expert on this.

Exact.
I'm using pfSense Plus which had that issue solved months ago. Works just fine.Example :
a phone connects on my 192.168.1.0/24 (LAN) network, and got a lease from the pfSense kea DHCP server on that network.
The "kea2unbound" script is the "bridge" (glue-ware ^^) that gets the IP and host name, and communicates it to unbound.
From now on, the IP con be resolved to the host name (reverse resolution) and host name to IP (resolution). -
Hello, it might work with the DNS Resolver, but not with the DNS Forwarder.
I am using KIA and the DNS Forwarder service and the dynamically set addresses are not resolved in the network.
I need to switch back to ISC because of that. :(
-
@mdima or just use unbound in forwarder mode. What does the forwarder service bring you that you can not do with unbound?
-
@johnpoz yes, I could do that, just I have to replicate a bit of settings currently set in the DNS forwarder.
This is an alternative to dodge the issue, just if KIA would work also with the DNS Forwarder would be nicer. (also, why is there a separate DNS Forwarder if there is such an option? :S)
-
@mdima not sure why the forwarder is still around to be honest, unbound was added and made the default years and years ago - you would think the forwarder would have dropped off by now. But the one thing I do know the forwarder still has a feature that I do not believe you can do with unbound is parallel. or sequential queries. Some users might want to ask all the nameservers at once and just use the first answer.. I do not believe unbound does that.
They might have kept it around because of the long standing problem with dhcp registrations in unbound causing restart of the service which can be problematic.. Now that they are fixing that aspect - maybe forwarder drops off at some point of being included?? I don't believe the forwarder had that problem?
I personally don't understand why with the ability to resolve users don't do that - but there are some cases where resolving has issues.. If you are on a really high latency connection, resolving can be problematic - but unbound can forward..

Oh finally! Thanks @herbcso for the tip. Just upgraded to 2.8.0, and now DHCP registration is working properly (including static mappings).
No need for a bunch of ugly Host Overrides on DNS Server anymore!
-
I'm using KEA DHCP and the "DHCP Registration" field is not present. I'm on 2.8.0. Per this post it should be in latter releases, which 2.8.0 is. Is there something else that I need to turn on?
-
@guiambros Hi, I just upgraded to 2.8.0 and Register DHCP leases in DNS Resolver, and the static mapping option are not present. Did you have to do anything specific to get these to show up?
-
@rocdiva Are you sure you're looking in the right service? The DHCP registration option is set in
Services/DHCP Server, but your screenshot shows theDNS Serverconfig. Here:

Thank you for pointing that out.

Hello all,
Thanks for pursuing this for months and years. I am finally returning to pfSense+ after time away because of things like this being fixed!
