Dynamic IP Updater with Cloudflare DNS

This project is a dynamic IP updater for Cloudflare DNS records. It listens for changes in the IPv4 address of the network interface and updates the DNS records in Cloudflare accordingly.

Features

Automatically detects changes in the public IP address.
Updates Cloudflare DNS records when the public IP changes.
Listens for network interface events to detect IP changes.
Handles errors and retries updates to Cloudflare.

Prerequisites

Rust and Cargo installed.
Cloudflare account with API token.
Network interface with dynamic IP address.

Installation

Clone the repository:

git clone https://github.com/yourusername/dynip-cloudflare.git
cd dynip-cloudflare

Build the project:
```
cargo build --release
```
Create configuration file:

Create a config.toml file in the current directory or in the configuration directory (typically ~/.config/dynip-cloudflare/) with the following content:
```
zone_id = "your_zone_id"
api_key = "your_api_key"
domains = ["example.com", "sub.example.com"]
max_errors_in_row = 5
```

Usage

Run the program:
```
./target/release/dynip-cloudflare
```
Logging:

The program logs to both stderr and a rotating file located in the logs directory. The log level is set to Info.

Configuration

`config.toml`

zone_id: The Zone ID of your Cloudflare domain.
api_key: The API key for your Cloudflare account.
domains: A list of domain names to update.
max_errors_in_row: Maximum number of consecutive errors before the program stops. Will be set to 10 as default

Example

zone_id = "your_zone_id"
api_key = "your_api_key"
domains = ["example.com", "sub.example.com"]
max_errors_in_row = 5

Error Handling

The program handles errors gracefully, with retries and logging of error messages. If the number of consecutive errors exceeds max_errors_in_row, the program will stop.
