ElvinRRD is a tool to provide a mechanism for transporting data across a network and storing it in RRD databases. It is written entirely in Python, and works with (and requires) both Elvin and RRDtool. Any Elvin producer/client can send data for ElvinRRD to store (e.g. EDDIE-Tool), and any RRD-aware software can process the resulting RRD databases.
Zoner is a Web application to make management of DNS zone files simple and easy. The authoritative copy of each domain remains in the original zone file, which Zoner reads and writes as needed, as opposed to storing domain details in a database. This means that zone files can still be edited manually and Zoner will pick up the changes as necessary. Zone serial numbers are incremented automatically when changes are made. Zoner can signal bind to reload a zone, via rndc. An audit of all zone changes is maintained for each domain.
