HostDB: The Best Damn host2DNS/DHCP Script Ever Written

Thomas Limoncelli, Cibernet Corp.


HostDB is a system for generating DNS zone files, BIND configurations, and ISC DHCP server configurations. It is extremely simple yet powerful, which makes it easy to deploy. It is not so complicated that it requires an SQL database or web server. It is not a single generation script but a complete system that includes tools for deploying the files that are generated. The system is written in Perl and shell and makes heavy use of make. The zone files that it generates look hand-made, except that they are clean. Powerful tools are also provided to aid in the conversion from legacy systems. HostDB is the third generation of my DNS maintenance systems and embodies not just superior software but also best practices in system administration. HostDB uses small tools that combine to achieve large goals. Initial deployment can be done in stages to reduce risk. Deployment of updates is fully automated. It rocks.
