dnstable_convert: conversion utilities for passive DNS data

Introduction

dnstable_convert is a conversion utility for passive DNS data in dnstable format. It was split out of dnstable to reduce the dependencies of dnstable.

dnstable_unconvert converts the RRSET entries of a dnstable file to the equivalent NMSG format.

dnstable_convert has the following dependencies:

• libdnstable, library for passive DNS data encoding functions.

• libmtbl, for encoding the underlying SSTable files in the MTBL format.

• libwdns, for low-level DNS utility functions.

• libnmsg, for importing passive DNS data in NMSG format. Additionally, the sie-nmsg message module (containing the SIE/dnsdedupe message type) is required. This complex dependency is not required by libdnstable.
