INWX DNS Authenticator plugin for Certbot
INWX DNS authenticator plugin for certbot
- certbot (>=0.15)
- setuptools (for manual installation; e.g.
For older Ubuntu distributions check out this PPA: ppa:certbot/certbot
- First install the plugin:
- Via Snap (requires certbot to be installed via snap):
snap install certbot-dns-inwx snap set certbot trust-plugin-with-root=ok snap connect certbot:plugin certbot-dns-inwx snap connect certbot-dns-inwx:certbot-metadata certbot:certbot-metadata
- Via PIP:
pip install certbot-dns-inwx
- Without dependencies (if using certbot from your distribution repository):
python3 setup.py develop --no-deps
- With dependencies (not recommended if using certbot from your distribution repositories):
python3 setup.py install
- With certbot-auto (deprecated for most platforms, needs to be reinstalled after every certbot-auto update):
/opt/eff.org/certbot/venv/bin/pip install .
Configure it with your INWX API Login Details:
with the following content (also see inwx.cfg of the repository):
dns_inwx_url = https://api.domrobot.com/xmlrpc/ dns_inwx_username = your_username dns_inwx_password = your_password dns_inwx_shared_secret = your_shared_secret optional
The shared secret is your INWX 2FA OTP code. It is shown to you when setting up the 2FA. It is not the 6 digit code you need to enter when siging in. If you are not using 2FA, simply keep the value the way it is.
Also note these remarks if you are using an older version of certbot.
Make sure the file is only readable by root! Otherwise all your domains might be in danger:
chmod 0600 /etc/letsencrypt/inwx.cfg
Request new certificates via a certbot invocation like this:
certbot certonly -a dns-inwx -d sub.domain.tld -d *.wildcard.tld
Renewals will automatically be performed using the same authenticator and credentials by certbot.
Usage on certbot < v1.7.0
Before certbot v1.7.0, third plugins needed to be accessed using their plugin name as prefix. If you are still using an older version of certbot, ensure to prefix all options in inwx.cfg and on the command-line with
certbot certonly -a certbot-dns-inwx:dns-inwx --certbot-dns-inwx:dns-inwx-credentials /root/inwx.cfg -d sub.domain.tld
Command Line Options
--dns-inwx-propagation-seconds DNS_INWX_PROPAGATION_SECONDS The number of seconds to wait for DNS to propagate before asking the ACME server to verify the DNS record. (default: 60) --dns-inwx-credentials DNS_INWX_CREDENTIALS Path to INWX account credentials INI file (default: /etc/letsencrypt/inwx.cfg)
certbot --help dns-inwx for further information.
This plugin supports redirections on the DNS-01 validation records using CNAME records.
For example, you can have a domain
a.tld which is not necessarily managed by INWX and possibly may not be automated via certbot. Additionally, you have a domain
b.tld which is managed by INWX.
An easy solution to automate certificate retrieval for
a.tld is to add a CNAME record for the name
a.tld which is pointing to i.e.
_a_validation.b.tld in your providers web interface.
A command like
certbot -a dns-inwx -d a.tld will then make certbot place its validation token at
_a_validation.b.tld via INWX and your validation for
NOTE: This is an optional feature and requires dnspython to be installed. To install it use your distribution repository or i.e.
pip install dnspython.
