chaos

Name

chaos - respond to TXT queries in the CH class

Description

This is useful for retrieving version or author information from the server by querying a TXT record for a special domain name in the CH class.

Syntax

chaos [VERSION] {
    authors {
        "First Author"
        "Second Author"
        ...
    }
}

• VERSION is the version to return. Defaults to atomdns-<version>, if not set.
• The authors section holds the authors that are returned.

Note that you have to make sure that this handler will get actual queries for the following zone prefixes: version., authors., hostname. and id., i.e. having version.example.org will suffice to get queries for the version. prefix.

Examples

Specify all the zones:

version.bind version.server authors.bind hostname.bind id.server {
    chaos atomdns-001
        authors {
            info@example.org
        }
    }
}

And test with dig:

% dig @localhost CH TXT version.bind
