KEA DHCP missing "Register DHCP leases in DNS Resolver..."
-
Glad I found this thread. I was trying to figure out why DHCP leases weren't resolvable on my home network when they once were. Forgot that I had cut over to KEA DHCP days ago. Reverted to ISC DHCP and checked "Ignore Deprecation Warning" - all better now.
-
I too followed the EOL suggestion and switch - and this is a total mess. How can I back this change out, I see nothing to switch back!!!
How can you POSSIBLY suggest this dysfunctional nonsense as an alternative? You've had this out for what, almost a year now - and it's still totally broken.
CAN YOU FIX YOUR BROKEN SH*T?!

"Administrators can easily switch between ISC DHCPD and Kea by navigating to System > Advanced, Networking tab and changing the new Server Backend setting in the DHCP Options section."
The wording in pfSense about ISC DHCP is a bit misleading but Kea is in "feature preview" a.k.a. alpha/beta/whatever.
-
The current goal is to have Kea at feature parity with ISC DHCP by the end of the year, then one release with Kea being optional, another release with Kea being the default for new installs, and finally another release to completely remove ISC DHCP entirely.

@SteveITS I switched it back but it still wouldn't resolve. I don't know what fixed it, perhaps DNS caches just had to expire, or my poking around in DDNS options (we don't use DDNS) fixed it. I think I enabled the DDNS host registration option without overall enabling DDNS. It's not clear if that has any effect or not, but after a while things were working again. Famous last words! Without it being at feature parity I think it's fine to as for testing feedback, but there shouldn't be a nag about it being deprecated. This suggests a need to migrate. It should also warn about a lack of feature parity, IMO.
-
Oh, I think I know why it took a while to return to normal: the migration wipes the existing leases, and it takes a while for clients to discover this and renew. Until that happens the client identifiers aren't going to be injected into DNS.

That's fair. The current warning definitely has a "the sky is falling" tone to it, which it certainly isn't.

This. 100% this. The warning gives the impression that one should update ASAP and gives zero indication that the replacement isn't feature complete.

Still an issue.

There is no longer a way to revert back in the GUI, so my setup is broken.
It should not have been released without better migration testing.

@uneventfullogs I believe you should be able to revert in System->Advanced->Networking. At least, that's where I've been able to do it in the past.
