Also, don't reload named, restart named when debugging. A few minor changes are necesary to your (isc dhcp3 server).
First, in the global portion: requests an address via dhcp, the dhcp server will tell the dns server.
As the DHCP servers in this environment are Linux based we would like the clients to update their PTR records themselves.
Updating the PTR records means a client registers his name and IP in the reverse lookup zone.
However, one area that Ubiquiti really falls down on is internal DNS resolution of DHCP hosts.The option notify no stops named (the DNS daemon) from forwarding information about the local network to external DNS servers.This is only useful if you use private addresses in your network.Luckily for us, there's a tool that'll do that for us. No, you shouldn't use that key for your server ;) The last token in that file is the key (N8Hk...). nsupdate is the tool we'll be using to test if we have setup the server correctly.That tool is called is a tool to create dnssec keys, much like ssh-keygen creates ssh keys. nsupdate takes commands like nslookup does, if run without arguments: Worst case, run named with a high debug level.
