Gandi-ddns

This is a simple python program that updated A and AAAA records using GANDI API. I made this for use on my linux machine, but should run on anything can can run python3.

Requirements

• python3.10 or more (the current version when created)
• Domain on gandi.net
• Gandi Public Api KEY

Installation

Download the repository

git clone https://gitlab.com/benmi/gandi-ddns.git

create a .venv

cd gandi-ddns
python3 -m venv .venv

add requirements to venv

.venv/bin/python3 -m pip install -r requirements.txt

Config file

create a "config.ini" file and use this template

[section1]
# gandi.net API key
apikey = s3cr3t4p1k3y
# Domain
domain = example.com
# record name
rrset_name = @
# record type
rrset_type = A
# rrset_ttl value 300 ~ 2592000
rrset_ttl = 320

or you can run the program once and it will create one for you

.venv/bin/python3 gandi-ddns.py

usage

for easy to understand reference to cron first set up a crontab

sudo crontab -e

if you have none, you might be prompted a to create one

no crontab for root - using an empty one

Select an editor.  To change later, run 'select-editor'.
  1. /bin/nano        <---- easiest
  2. /usr/bin/vim.basic
  3. /usr/bin/vim.tiny
  4. /bin/ed

Choose 1-4 [1]: 

if you dont know what this is, just press 1 then enter. this will open up a text editor with an example page

create a new line with this to have your pc run the script at boot

@reboot /path/to/gandi-ddns/.venv/bin/python3 /path/to/gandi-ddns/gandi-ddns.py &

create a new line with this to have it run the script every 15 minutes

*/15 * * * * /path/to/gandi-ddns/.venv/bin/python3 /path/to/gandi-ddns/gandi-ddns.py

if you used text editor 1, nano you can now press ctrl+x, then press y, then press enter to save and exit the file

Then to start the crontab run

sudo /etc/init.d/cron start
sudo /etc/init.d/cron reload

Problems

if you have any problems with the script feel free to open an issue. I will later add a FAQ for often seen problems.
