I asked recently on the mailing-list of <a different DNS server> :)
about adding zones on the fly, and it occurs to me that I have exactly
the same questions about `nsd-control addzone|delzone`.
I'd appreciate if you could help me clarify a few things, please.
1. Is NSD 'deaf' during an `addzone'? I don't think so, but I'm finding
it hard to determine definitely. I'm primarily concerned with NSD
being able to handle any NOTIFYs it gets.
2. When I `addzone' a slave zone, NSD immediately picks
that up, transfers the zone and creates the specified file. However,
`delzone', while it drops the zone from NSD, does not remove
the zone file from the file system. Is that a bug or was that
It seems a bit illogical to me that the zone file isn't removed from
the file system: what NSD creates it can remove. :-)
3. If I direct `addzone|delzone' at the same NSD instance from
multiple processes (on differing source IP address), is there any
danger of the zonelist file being corrupted? Would there be a locking
Thanks for clarification.
