Configuring OpenDNSSEC has a number of aspects:
Configuration Files
These can be customised for each installation, although the default configuration installs good default values. The individual files and tools to check the configuration files are described here.
Keys
Configure your HSM as required.
Zones
Check the supported zone formats.
External Auditing of Zones
The auditor component of OpenDNSSEC was removed in 1.4. The Zone Auditing page describes alternative validation tools and configurations.
