Usage

Installation

• Copy all files to your webspace

• create a copy of .env.dist as .env and configure:

  • username -> The username for your Router to authenticate (so not everyone can update your DNS)
  • password -> password for your Router
  • apiKey -> API key which is generated in netcup CCP
  • apiPassword -> API password which is generated in netcup CCP
  • customerId -> your netcup Customer ID
  • debug -> true|false enables debug mode and generates output of update.php (normal operation has no output)

• Create each host record in your netcup CCP before using the script. The script does not create any missing records.

AVM FRITZ!Box Settings

• Go to "Internet" -> "Freigaben" -> "DynDNS"
• Choose "Benutzerdefiniert"
• Update-URL: https://<url of your webspace>/update.php?user=<username>&password=<pass>&ipv4=<ipaddr>&ipv6=<ip6addr>&domain=<domain>
  • only the url needs to be adjusted, the rest is automatically filled by your AVM FRITZ!Box
  • http or https is possible if valid SSL certificate (e.g. Let's Encrypt)
• Domainname: <host record that is supposed to be updated>
• Username: <username as defined in .env file>
• Password: <password as definied in .env file>

run as cronjob on a **nix based device
