NethServer Version: NethServer release 7.5.1804 (final)
Module: NSDC (DNS)
It seems I have an invisible DNS entry hiding out somewhere!
I am administering DNS from Windows RSAT. I had created a forward DNS (A record) entry for xyzServer with an IP Address of 10.x.y.z. I then deleted that entry. Attempting to recreate the entry with the same name and IP Address results in an error:
The host record xyzServer.internal.domain cannot be created. The record already exists.
If I attempt nslookup of this already extant record my DNS connection to the NSDC times out and will not return until after a reboot.
I can create a record with a different name and the same IP. I can create a record with the same name and a different IP. Other new records can be created, deleted, recreated, kai ta hetera, et cetera, ad nauseam and at will. Just xyzServer with IP Address 10.x.y.z cannot be created.
I assume there’s something to be done from the terminal on the NSDC itself to resolve this, however; I haven’t been able to find what that might be. Any hints or helps are appreciated!
