# Gandi-dyndns

A simple script to update Gandi DNS records.

# Requirements
You will need the following python packages:
- pyyaml, to parse the configuration file
- requests, to perform the DNS record change

# Getting started
1. Copy the [script](./src/update_dns.py) somewhere
2. Allow script execution:
```bash
$ chmod u+x ./update_dns.py
```
3. Create a configuration file (see [the example](./example_config.yml))
4. Launch the script:
```bash
$ ./update_dns.py /path/to/config.yml
```
5. Install the systemd [service](./systemd/update_dns.service) and [timer](./systemd/update_dns.timer) for automatic DNS update.
```bash
$ vim ./systemd/update_dns.service # update parameters, config file, etc.
$ vim ./systemd/update_dns.timer   # update interval between DNS updates, if needed
$ sudo cp ./systemd/update_dns.* /etc/systemd/system # copy files to correct systemd directory
$ sudo systemctl daemon-reload              # reload daemon to find the timer
$ sudo systemctl enable update_dns.timer
$ sudo systemctl start update_dns.timer
```
