ddnss

Dynamic Domain Name Service Switch

Introduction

Simple Python HTTP server that reads a callers IP and saves it to a folder. An NSS module on the host will then use these saved IPs to connect them with a specified hostname, ending with .ddnss as TLD. The endpoint is secured using Basic HTTP Auth.

Setup

SSL

Use a proxy (e.g. nginx) for SSL connections.

Server in Docker

Server example for docker-compose, see docker-compose.yaml

Client in Docker

Nginx client example for docker-compose docker-compose-nginx-ddnss.yaml

or

curl -u myuser:mypassword https://ddnss.example.com/myhost/set -X POST -F "ip=127.0.0.1"
