Introduction
------------

This will aim to document how to provide access to the internal data structure of the metaserver via simple dns queries.

The Goal
--------

Forward Searching (searches by attribute 'name'):
dig -t A foobar @dns.server

foobar A 1.2.3.4

Reverse Searching (searches by attribute 'ip'):
dig -t PTR 1.2.3.4 @dns.server

foobar A 1.2.3.4

Where:

m_serverData = {
     '1.2.3.4' => {
	'ip' => '1.2.3.4',
	'expiry' => 'boost datetime string',
	'port' => '1234',
	'ip_int' => '123456',
	'name' => 'foobar'
      }
}

Reference
---------

 The PDNS backend for the metaserver was implemented via the PipeBackend for PDNS.  The full list of references used are:

 http://doc.powerdns.com/backend-writers-guide.html
 http://doc.powerdns.com/pipebackend-dynamic-resolution.html
 http://doc.powerdns.com/backends-detail.html#pipebackend
 http://doc.powerdns.com/backends-detail.html#pipebackend-protocol


PDNS Configuration
------------------

pipebackend-abi-version=1
pipe-command=/home/sryan/wf/metaserver-ng/src/pdnspipe
pipe-timeout=2000

NOTES
-----

- this is known to not function correctly, as pdns is attempting to axfr and recurse in an unexpected fashion.  This needs to be investigated.
