On open SUSE setting the DHCP hostname in the interface settings doesn't seem to work you need to use the send host-name "hostname" feature of but beware that hostname should not be fully qualified as the example suggests.Dynamic Dns Update Security When you set your DNS server up to allow updates from the DHCP server, you may be exposing it to unauthorized updates.This is why I mentioned the use of send host-name in my post.Oh yeah I did update that part as well but all but one of my machines are windows machines.To do so, you need to add something like this to your file: key DHCP_UPDATER ; zone EXAMPLE. Note that the zone declarations have to correspond to authority records in your name server - in the above example, there must be an SOA record for "" and for ".".For example, if there were a subdomain "foo.example.org" with no separate SOA, you could not write a zone declaration for "foo." Also keep in mind that zone names in your DHCP configuration should end in a "."; this is the preferred syntax.
You should be able to do this on Windows or Linux (but the keytab must be copied to the server running ISC DHCP).I've been unsuccessful at finding a guide on how to integrate just ISC DHCP into an AD DNS environment.The configuration file is below, but what I've noted when using ISC DHCP is that non-domain joined clients will not have an A record registered for them in forward/reverse lookup zones.Note, however, that the DHCP protocol itself provides no security, and that clients can therefore provide information to the DHCP server which the DHCP server will then use in its updates, with the constraints described previously.The DNS server must be configured to allow updates for any zone that the DHCP server will be updating.
