Create DNS records for DHCP leases

◀ Go back to main README

Description

This script adds (and removes) dns records based on dhcp server leases.

Requirements and installation

Just install the script:

$ScriptInstallUpdate dhcp-to-dns;

Then run it from dhcp server as lease script. You may want to use lease-script.

A scheduler cares about cleanup:

/ system scheduler add interval=15m name=dhcp-to-dns on-event="/ system script run dhcp-to-dns;" start-time=startup;

Configuration

On first run a disabled static dns record acting as marker (with comment "--- dhcp-to-dns above ---") is added. Move this entry to define where new entries are to be added.

The configuration goes to global-config-overlay, these are the parameters:

• Domain: the domain used for dns records
• HostNameInZone: whether or not to add the dhcp/dns server's hostname
• PrefixInZone: whether or not to add prefix dhcp
• ServerNameInZone: whether or not to add DHCP server name
