Gandyndns

What is Gandyndns?

Gandidyndns is a dynamic IP updater based on Gandi LiveAPI. It can handle IPv4 and IPv6 although care should taken for IPv6 if you use dynamic/temporary addresses.

How does it work?

Well, read the code, it's pretty simple :] In short, it does the following for each domain that has to be updated:

1. Retrieve current address(es) from http://whatip.me For each type of each record of each domain from the configuration:
2. Retrieve current record from gandi
3. If both records match, current record is up to date!
4. If not, we upgrade gandi with current record informations Done.

How to install it?

python3 setup.py install

If you do not plan to share it among different users, you can (and maybe should) install it in your own user site-package directory with:

python3 setup.py install --user

You can also install it in a virtualenv.

How to use it?

Configuration file is written in json format.

Basic configuration

{
    "domains": {
        "example.com": {
            "apikey": "d41d8cd98f00b204e9800998ecf8427e",
            "records" : {
                "test": {
                    "A": {
                        "rrset_values":["{remote_addr}"]
                    }
                }
            }
        }
    }
}

You can either have different config files or have multiple domains in the same config file, as you wish.

Basic usage

$ gandyndns /path/to/gandyndns.conf

Gandyndns does not need any priviledge besides internet access to run, so avoid running it as root.
