README

chaos

The chaos middleware allows CoreDNS to respond to TXT queries in the CH class. This is useful for retrieving version or author information from the server.

Syntax

chaos [VERSION] [AUTHORS...]

• VERSION is the version to return. Defaults to CoreDNS-<version>, if not set.
• AUTHORS is what authors to return. No default.

Note that you have to make sure that this middleware will get actual queries for the following zones: version.bind, version.server, authors.bind, hostname.bind and id.server.

Examples

chaos CoreDNS-001 "Miek Gieben" miek@miek.nl
