gdnsd.djbdns - gdnsd support for the djbdns tinydns zone data format





This zone data backend implements the tinydns format described in <>.

As of this writing, djbdns file format support is considered EXPERIMENTAL. Feel free to submit issues and/or pull requests to make the implementation and documentation more correct and complete! There are probably many legal djbdns zone datasets that do not load correctly (or at all) yet. However, there are users loading data from this in production.

The djbdns zone data backend loads all files found within the djbdns subdirectory of the daemon config directory, default /usr/local/etc/gdnsd/djbdns/. Each file can contain multiple zones (identified by Z records).

At this time, unlike the RFC1035 zone data backend, the djbdns backend does not support automatic reloading of updates based on filesystem notification. It only explicitly reloads any changed data on SIGUSR1 / gdnsd reload-zones.


The following record types are implemented in the parser:
Z - SOA The Z type denotes the existence of a zone and defines its SOA-record. All records within a file must be contained within a zone defined by a Z entry.
& - NS (+ A) Implemented.
. - NS + SOA (+ A) The . type is meant to create an SOA along with the zone’s NS records. At this time, gdnsd doesn’t support this record for defining the SOA or a zone’s existence, and treats it just like & above.
@ - MX (+ A) Implemented.
+ - A If the 5th field is ~~, this can be used to create DYNA records as well, with the plugin!resource part in the 2nd field.
= - A + PTR The autogeneration of PTR records for = is not implemented yet, so this is treated identically to + above.
C - CNAME If the 5th field is ~~, this can be used to create DYNC records as well, with the plugin!resource part in the 2nd field.
\ - TXT Implemented.
S - SRV Implemented.
N - NAPTR Implemented.
3 - AAAA Not yet implemented.
6 - AAAA + PTR Not yet implemented.
^ - PTR Not yet implemented.
: - Raw Not yet implemented.
