UBNT-DDNS-IPv6

Why use this script?

Because the ddclient in EdgeRouter firmware is 3.8.3, which doesn't support DDNS in IPv6. This script is aimed to upgrade the ddclient to 3.9.0.

How does this script works

Simply install a few perl modules which required by ddclient 3.9.0 and doesn't exist in the firmware, then replace the ddclient.

List of perl modules needed to be installed.

libnetwork-ipv4addr-perl
libnet-ipv6addr-perl
libnet-netmask-perl
libdata-validate-ip-perl
libio-socket-inet6-perl

Tested firmware

Device	Version

Installation

Use SSH to connect to your Router

Install the script and upgrade the ddclient

sudo su -
curl -o /config/scripts/ddclient.sh https://raw.githubusercontent.com/SpartaEN/ubnt-ddns-ipv6/master/ddclient.sh
chmod +x /config/scripts/ddclient.sh
sh /config/scripts/ddclient.sh

Make the script a scheduled task to auto upgrade the ddclient after firmware upgrade

configure

commit

NOTICE

Since some modules have been removed for wheezy, I switched to Stretch.
