# gandyndns
|
|
The purpose of this script is to change *on execution* the IP address of a Gandi.net DNS record (default is to change the DNS @.example.com A record)
|
|
and replacing the IP with the public IP of the machine on which the code is executed. The goal is to provide a dynamic change of DNS record like DynDNS, DuckDNS, etc for Gandi.net domains.
|
|
|
|
This script was inspired by matt1's gandi-ddns script : [matt1/gandi-ddns](https://github.com/matt1/gandi-ddns)
|
|
|
|
## Usage
|
|
|
|
```
|
|
usage: gandyndns.py [-h] [-v] [--type TYPE] DOMAIN SUBDOMAIN APIKEY
|
|
|
|
A script which connect to Gandi.net API to change IP associated to a DNS record
|
|
|
|
positional arguments:
|
|
DOMAIN The domain for which you want to write a DNS record. Example: example.com
|
|
SUBDOMAIN The subdomain to point to. Examples: 'sub' or '@'
|
|
APIKEY Your Gandi.net API key
|
|
|
|
options:
|
|
-h, --help show this help message and exit
|
|
-v, --verbose Enable verbose mode
|
|
--type TYPE The type of DNS record to create. Default: A
|
|
```
|
|
|
|
Each time the script runs it check if *the IPs in the DNS record* match the *current public IP* and if they dont use a PUT request to apply the new IP to the DNS.
|
|
|
|
## Automation : **Run the script using a cron task**
|
|
|
|
```bash
|
|
sudo crontab -e
|
|
```
|
|
|
|
And then to execute *every X minutes* (where X should be an integer between 1 and 59) write in the crontab :
|
|
|
|
```
|
|
*/X * * * * python /path/to/script/gandyndns.py example.com @ my-api-key
|
|
```
