This is my custom dynamic domain name service (ddns) client. This only works with cloudflare currently, as it is the dns provider I am using. It shouldn't be too hard to add support for other providers.
The project is also currently only targeting debian, as it is the only operating system relevant to my use case. It shouldn't be too hard to add support for other operating systems, as this is a relatively simple program. Finding the current ipv6 address is the only thing that might be a bit tricky.
use gcc ddns.c -o ddns to compile.
To get started with config.ini rename config.example.ini to config.ini and change the values to suit you.
Booleans are represented as 1 and 0.
At the top of the file there should be Initialization configuration. The fields are:
token Cloud flare api token.
v4 Wether ipv4 is enabled. Useful in networks without ipv4.
v6 Wether ipv6 is enabled. Useful in networks without ipv6.
interval How often to check if ip has changed in seconds.
After that configuration for the records. The fields are:
zone The cloudflare hosting zone.
name The name of the record.
ipv4 The id of the record, if the id is ipv4
ipv6 The id of the record, if the id is ipv6
It is extremely important that both zone and name have been defined before ipv4 or ipv6. The records use the last defined zone and name.
