Description:

ddupdate 0.7.1

General
ddupdate is a tool for automatically updating dns data for a system using
for example DHCP. It makes it possible to access such a system with
a fixed dns name like myhost.somewhere.net even if the IP address is
changed. It is a linux-centric, user-friendly and secure alternative to
the ubiquitous ddclient.
Compared to ddclient, ddupdate is much easier to configure for users. It’s
also more flexible and provides support for some hosts which are known to
be problematic using ddclient.


Status
Beta. The plugin API will be kept stable up to 1.0.0, and there should be
no incompatible CLI changes.
At the time of writing 20 free services are supported. There is also 7
address plugins. Together this should cover most usecases based on freely
available services.
Still, this is beta and there is most likely bugs out there.


Dependencies


python3 (tested on 3.6 and 3.4)
The /usr/sbin/ip command is used in some plugins.
python3-setuptools (build)
pkg-config (build)
The systemd package i. e., the systemd.pc file (build).




Installation
ddupdate can be run as a regular user straight off the cloned git
directory. To make it possible to run from anywhere make a symlink:
$ ln -s $PWD/ddupdate $HOME/bin/ddupdate
It is also possible to install as a pypi package using:
$ sudo pip3 install ddupdate --prefix=/usr/local
See CONTRIBUTE.md for more info on using the pypi package.
ddupdate is packaged in some distros:


Fedora 27 and later.
EPEL7 addons for RHEL/CentOS
Debian Buster and later
Ubuntu Bionic and later


CONTRIBUTE.md describes how to create packages for other Debian
distributions
Ubuntu users can install native .deb packages using the PPA at
https://launchpad.net/~leamas-alec/+archive/ubuntu/ddupdate
Mageia users can install native rpm packages from
https://copr.fedorainfracloud.org/coprs/leamas/ddupdate/. This site also
contains pre-release updates for Fedora and EPEL.
Overall, using native packages is the preferred installation method on
platforms supporting this.


Configuration
This is the fast track assuming that you are using a native package and
mainstream address options. If running into troubles, see the manual
steps described in CONFIGURATION.md.
Start with running `ddupdate --list-services`. Pick a supported
service and check it using `ddupdate --help <service>`.
At this point you need to register with the relevant website. The usual
steps are to first create an account and then, using the account, create
a host. The process should end up with a hostname, a user and a secret
password (some sites just uses an API key).
Then start the configuration script `ddupdate-config`. The script
guides you through the configuration and updates several files, notably
~/.config/ddupdate.conf and ~/.netrc.
After running the script it should be possible to run a plain
`ddupdate -l debug` without error messages.
When this works, systemd should be configured as described below.


Configuring systemd
systemd is setup to run as a user service. Start by testing it:
$ systemctl --user daemon-reload
$ systemctl --user start ddupdate.service
$ journalctl --user -u ddupdate.service
If all is fine make sure ddupdate is run hourly using:
$ systemctl --user start ddupdate.timer
$ systemctl --user enable ddupdate.timer
If you want the service to start as soon as the machine boots, and to
continue even when you log out do:

sudologinctlenable−lingerUSER

If there is trouble or if you for example want to run ddupdate more often,
use systemctl –user edit ddupdate.service`or `systemctl –user edit
ddupdate.timer


Configuring NetworkManager
NetworkManager can be configured to start/stop ddupdate when interfaces goes
up or down. An example script to drop in /etc/NetworkManager/dispatcher.d
is distributed in the package.
