Reverse DNS

The DDNS adapter uses the dynamic DNS protocol to send updated PTR DNS records to your DNS system as nodes are provisioned into Horizon.

For every IP address found, a corresponding reverse DNS zone must exist on your DNS server.

Installation

To use this feature you have to install the reverse DNS provisioning plugin from the repository.

  • For RPM-based distributions:

    • yum install opennms-plugin-provisioning-reverse-dns

  • For Debian-based distributions:

    • apt-get install opennms-plugin-provisioning-reverse-dns

Configuration

To configure this adapter, create a .properties file in the ${OPENNMS_HOME}/etc/opennms.properties.d/ folder and set the importer.adapter.dns.server property:

importer.adapter.dns.server=192.168.1.1 (1)
1 Replace with the IP address of your DNS server to receive reverse DNS updates.
This DNS server setting may be shared with the dynamic DNS adapter if you have them both installed.
