web-nsupdate - Dynamic DNS service
The "web-nsupdate" package provides dynamic DNS services for domains that you serve with the BIND9 DNS server. This allows devices with dynamic addresses on the Internet, such as a home broadband router, to have a stable domain name.
Dynamic updates for both IPv4 and IPv6 addresses (DNS "A" and "AAAA" records) are supported.
IMPORTANT -- If you do not have a BIND server already setup and running then stop now. This package is a front-end service to clients, allowing them to easily register dynamic DNS changes. It requires a running back-end service such as BIND9 to manage the DNS.
The service is implemented in PHP and runs under a web server such as Apache.
Client updates may be performed any of the following ways:
- a DynDNS-compatible client (http://en.wikipedia.org/wiki/DynDNS)
- simple web request, using "curl" or a similar utility
- manual input via built-in web form
The included "ddns-check.sh" script illustrates the second method. It runs "curl" to perform a DNS update. It's based on a script that I run periodically (every 5 minutes) on my network, to contact the "web-nsupdate" service and make updates.
