# Introduction

The Onamae.com Dynamic DNS (DDNS) client supports only Windows. However, using ddns-scripts-onamae, you can update Onamae.com DNS records from a router running OpenWrt.

ddns-scripts-onamae is a submodule of the ddns-scripts package, which supports DDNS management on OpenWrt. It provides a function for automatically updating DNS records for Onamae.com, a widely used domain registrar in Japan.

This allows you to keep a hostname registered with Onamae.com synchronized with the latest IP address using an OpenWrt router, even when your internet connection does not have a static IP address.

This article explains how to automatically update Onamae.com DNS records from OpenWrt using DDNS and ddns-scripts-onamae.

# Install ddns-scripts-onamae

Visit the ddns-scripts-onamae download site and check the latest package version. In this example, v1.0.2 is used.

Access OpenWrt over SSH and download the package with wget.

wget -O /tmp/ddns-scripts-onamae.ipk https://github.com/ktdevx/ddns-scripts-onamae/releases/download/v1.0.2/ddns-scripts-onamae_1.0.2-r1_all.ipk

The ddns-scripts-onamae package is saved as ddns-scripts-onamae.ipk in /tmp. Install it with opkg install.

opkg update
opkg install /tmp/ddns-scripts-onamae.ipk

The ddns-scripts-onamae installation is complete.

# Configure DDNS

Open /etc/config/ddns in a text editor and append the following configuration.

config service "example_com"
    option service_name "onamae.com"
    option lookup_host  "example.com"
    option domain       "@example.com"
    option username     "<Onamae.com Navi ID>"
    option password     "<Onamae.com Navi password>"
    option interface    "wan"
    option ip_source    "network"
    option ip_network   "wan"
    option use_ipv6     "0"
    option enabled      "1"

This adds a service named example_com that updates the example.com domain with the IP address of wan. Change the following settings for your environment.

SettingDetails
lookup_hostDomain name (FQDN) whose IP address is updated
domainDomain name to update (subdomain@domain)
usernameOnamae.com Navi ID
passwordOnamae.com Navi password
interface / ip_networkNetwork from which to read the IP address

For a subdomain, configure lookup_host and domain as follows.

    option lookup_host  "sub.example.com"
    option domain       "sub@example.com"

After configuring the service, restart it with the following command.

service ddns restart

The DDNS configuration is complete. DNS records are now updated automatically.
