Simple RFC2136 update HTTP server
State: Worksforme
The purpose of this project is to allow some home routers to publish their IP to a RFC2136 Nameserver. ddnsd serves a http server and responds to get requests and creates a RFC2136 update message to update a remote dns server.
Example for Fritzbox:
http://example.com:8080/api/dns/?ip=<ipaddr>&hostname=<domain>&token=<pass>
The given "hostname" or "domainname" sould be relative to the zone specified in config file.
ddnsd.conf:
---
Listen: ":8080"
BasePath: "/api"
Nameserver: a.ns.example.com:53
TTL: 3600
Zone: ddns.example.com.
Token: test
Secret: <secret>
Installation
