Dynamic DNS client.
gddns is designed to be a simple and robust client for the DynDNS API.
gddns has been tested on deSEC, and No-IP, but should work with any of several other dynamic DNS service using the DynDNS API.
Look for pre-built binaries in the releases.
You can also build from source:
git clone https://github.com/julianandrews/gddns
cd gddns
cargo build --release
and use the gddns binary at target/release/gddns.
Install the .deb package from the releases page, edit
/etc/gddns/config.toml with configuration for your particular domain(s), and
then run:
sudo systemctl enable --now gddns.service
You will need to:
- create a config file,
- create a cache directory with write access, and
- either
- run gddns in daemon mode, or
- periodically run gddns (potentially with a systemd timer or cronjob).
By default gddns looks for a config file at /etc/gddns/config.toml and will
update all configured hosts. See pkg/config.toml for a concrete example.
The user running gddns must have write permissions to the cache directory. By
default this is /var/cache/gddns. This can be overridden in config.toml, or
by command line option.
Files in the cache directory can be deleted if the cache gets out of sync. In that case, gddns will send an update request the next time it is run.
If properly configured, you can simply run
gddns
and gddns will update all configured dynamic DNS hosts.
gddns daemon
will launch gddns and regularly poll your IP address looking for changes.
See gddns --help for detailed options.
You can also invoke gddns directly for a single host:
gddns update-host <your_hostname> --cache-dir /tmp/gddns \
--username <your_username> --password <your_password> \
--dyndns-url "https://domains.google.com/nic/update"
