Description

This module manages Unbound.

RHEL/CentOS and OpenBSD are supported using Puppet 4.6.0 or later.

Setup

Beginning with unbound

In the simplest case, configure Unbound listening on all interfaces:

include ::unbound

Usage

Update the above example to specify the forwarders to use and allow access from the local network, also restrict outbound ports used to avoid anything below 32768 and above 65000:

class { '::unbound':
  access_control => [
    ["${::network}/${netmask_to_masklen($::netmask)}", 'allow'],
    ["${::network6}/${netmask_to_masklen($::netmask6)}", 'allow'],
  ],
  outgoing_port  => [
    ['avoid', 0, 32767],
    ['avoid', 65001, 65535],
  ],
}

::unbound::forward { '.':
  forward_addr => [
    '8.8.8.8',
    '8.8.4.4',
    '2001:4860:4860::8844',
    '2001:4860:4860::8888',
  ],
}

Configure NSD listening on the primary interface as a slave for a single zone protected with a given TSIG key and configure Unbound listening on the loopback interface only with a stub zone pointing to NSD:

class { '::nsd':
  ip_address => [
    $::ipaddress,
    $::ipaddress6,
  ],
}

::nsd::key { 'example.':
  algorithm => 'hmac-sha256',
  secret    => '6z+8iKRIQrwN43TFfO/Rf2NHzpHIFVi6PsJ7dDESclc=',
}

::nsd::zone { 'example.com.':
  allow_notify => [
    ['192.0.2.1', 'example.'],
  ],
  request_xfr  => [
    ['AXFR', '192.0.2.1', 'example.'],
  ],
}

class { '::unbound':
  interface => [
    $::ipaddress_lo,
    $::ipaddress6_lo,
  ],
}

::unbound::stub { 'example.com.':
  stub_addr => [
    $::ipaddress,
    $::ipaddress6,
  ],
}

If NSD is not required then local data can be used instead:

class { '::unbound':
  interface  => [
    $::ipaddress_lo,
    $::ipaddress6_lo,
  ],
  local_zone => [
    ['example.com.', 'static'],
  ],
  local_data => [
    {
      'name'     => 'example.com.'
      'ttl'      => 86400,
      'class'    => 'IN',
      'type'     => 'NS',
      'hostname' => 'ns1.example.com.',
    },
    {
      'name'     => 'example.com.'
      'ttl'      => 86400,
      'class'    => 'IN',
      'type'     => 'SOA',
      'primary'  => 'ns1.example.com.',
      'email'    => 'hostmaster.example.com.',
      'serial'   => 1,
      'refresh'  => 10800,
      'retry'    => 15,
      'expire'   => 604800,
      'negative' => 10800,
    },
    {
      'name'  => 'ns1.example.com.',
      'ttl'   => 86400,
      'class' => 'IN',
      'type'  => 'A',
      'ip'    => '192.0.2.1',
    },
  ],
}
