      Yep. The KEA documentation - and for that matter, ISC DHCP states :
      NTP name server fields in are 'IP' - not a host name.
      The DHCP server KEA and ISC DHCP are not going tot resolve that host name. The DHCP RFC says : NTP servers are 'IP', not a host name.
      Here you can see what a DHCP server should hand over to a client : rfc2132 => that's IPv4 addresses.
      The pfSense GUI help message is :

      390233df-ab5a-4795-b7b4-c7cd9bbe67b7-image.png

      and is plain wrong. It's just a IP, no a host name, and even less a pool.

      I guess ISC DHCP silently ignored it as a NTP host name was given, KEA just bails out with a log-error message.

      Going even further :
      I've got several Windows based PCs here, a version 7, a 10 and several 11 : none are using the NTP server IP (192.168.1.1) that came with DHCP ...
      My iPhone, Pad etc : same thing.
      Androids : let me guess ^^

      I'm not even sure why I've set this NTP field. Maybe it will work some day.

      No "help me" PM's please. Use the forum, the community will thank you.
      Edit : and where are the logs ??

        You’d think after over 20 years we’d just give up on the idea of anyone ever taking it up. ;)

          @Gertjan That is all correct, but not the point.

          The point is that the banner suggests that you should go to System > Advanced > Networking and switch DHCP backend. It should have pointed to a explanation page with the current limitations, because as it is people waste a lot of time.

          Also both the ISC and the KEA page let you enter a FDQN without a warning. KEA brakes on a FDQN, ISC does not.

            I've made a special script that is called via Kea's hooks and live update unbound on each kea's lease update via unbound-control:

            As i'm not an sh guru, feel free to make any pull requests !

              Oho !
              (something very like) This is all that Kea needs so it can register a host name into "unbound" as soon as it comes in.

              👍

              Question :

              bc2240fa-cdcb-4627-9d6e-2dba6d499c32-image.png

              shouldn't that be :

              UNBOUND_CONTROL_PATH="/usr/local/sbin/unbound-control"
              UNBOUND_CONFIG_PATH="/var/unbound/unbound.conf"
              

              ?

                  Noop.
                  pfSense Plus and CE are very, like a lot, identical, when it comes to these kind of details.
                  IMHO, Plus and CE have a common build source base.
                  Plus has some value added packages added, and some low level stuff that permits it to run on Azure.
                  Plus has also ZFS file system kernel module loaded, so it can use ZFS as an option.
                  Things like that.
                  Core functionalities like "DNS", or "DHCP", are the same.

                    The example given is not matching pfsense specificaly.
                    For pfsense, of course, You're entirely right.
                    For other OSes, depends on the standard path of un
                    bound and kea's installation.
                    I'll add an example file for pfSense along the provided patch.

                      @Gertjan Yes again CE starts with a different subfolder over Plus I think patches show a different root folder

                        As does CE. Plus has the tools for managing the ZFS system via the front end included, though, as a Plus.

                          Maybe install System_Patches, there are 2 Kea patches and 2 DNS resolver.

                              Also of note, since the security notes are not yet in the 23.04 release notes:

                              When upgrading, allow 10-15 minutes to restart, or more depending on packages and device speed.

                                @4o4rh as @SteveITS already posted the answer, install system patches, then go to System -> Patches and apply them. More to read here https://www.netgate.com/blog/using-pfsense-software-system-patches .

                                  @Qinn doesn't really answer the question. Where do we get a list of the patches available and what they are for?

                                    Install this package, you see a list recommended system patches for Netgate pfSense and for each patch there is a description what it does or do. After you installed the package see this list and you can choose to apply each one of them individually (even revert most of them if you for some reason want to) or change nothing and remove the whole package, as in the link above this package is recommended by Netgate.

                                        @4o4rh what version are you on? 24.03 has none because their code is included.

                                        Typically patches appear either a few weeks/months after a release, to fix bugs, or else they dropped a bunch of them for 2.7.2/23.09 after 24.03 was released because there are security fixes they backported for 2.7:2,

                                        Patches appear after the package is updated not on their own.

                                          Same question here ;)

                                          Btw I am on 2.7.2 CE ( as is in my signature) and use System_Patches v2.2.10_1, updated recently, say last week and as you can see patches are sane to install, as like this example https://redmine.pfsense.org/issues/14991 is target for the not released pfSense version 2.8.0

                                            I somehow got burned by this too. No, I do not read release notes, I just trust that the latest and greatest firmware protects my family's network. I had some performance issues on my ISP so rebooted everything to try to fix and it took me several hours to get to a root cause. I am sad, but happy to have it all back up and running nicely. Next time I will be more leery!
