Tenshi

Tenshi is a fast CLI utility that fetches a curated hosts file, generates Unbound local-zone entries from it, and saves them to /etc/unbound/local-blocking-data.conf.

At the moment, only Steven Black's hosts file is used.

Tenshi is primarily written to work on Linux, but it will likely work on the BSDs. It is untested on Macintosh, and will probably not work on Windows.

You will want to add include: "local-blocking-data.conf" to your Unbound config to use the result.

Installation

Prerequisites

Tenshi must be run as a user that has write access to /etc/unbound/local-blocking-data.conf.
