Update multiple dynamic DNS servers at once.

Multiple Dynamic DNS

This script updates multiple DDNS entries at once. My FritzBox router can only update a single DDNS entry. Therefore I run this script on my (local) server, my FritzBox sends an update to this script, which in turn updates multiple other DDNS entries.

Security Notes

• Currently the server does not provide any encryption. Do not use this over the internet or a "public" intranet!
  • The option to enable TLS is only for testing, my FritzBox doesn't work with self signed certificates.
• DDNS service credentials are stored in plaintext.

Usage Example

• Copy config.json.example to config.json and enter the necessary information.
• Make files executable:

chmod ug+x multiddns/server.py multiddns/update/updater.py

• Open crontab -e and insert the following line to start the server at startup:

@reboot <path to repo>/multiddns/server.py > /dev/null 2>&1

Generate self signed certificate

openssl req -x509 -newkey rsa:4096 -keyout key.pem -out certificate.pem -days 3650

(Use a password)
