certbot-dns-standalone's Introduction

Standalone DNS Authenticator plugin for Certbot

This is a plugin that uses an integrated DNS server to respond to the _acme-challenge records, so the domain's records do not have to be modified.

Installation

pip

# pip3 install certbot certbot-dns-standalone

snap

# snap install certbot certbot-dns-standalone
# snap set certbot trust-plugin-with-root=ok
# snap connect certbot:plugin certbot-dns-standalone
# snap connect certbot-dns-standalone:certbot-metadata certbot:certbot-metadata

Debian

# apt-get install certbot python3-certbot-dns-standalone

Usage

First, you need to pick a central address for certbot, e.g. acme.example.com.

Next, the _acme-challenge records need to be pointed to $domain.acme.example.com using CNAME records, e.g. for example.net:

_acme-challenge  IN  CNAME  example.net.acme.example.com.

Finally, you need to point *.acme.example.com to certbot. There are two options for that.

Firstly, if you have an IP address with port 53 available, you could configure it as the nameserver for acme.example.com:

acme     IN  NS  ns.acme.example.com.
ns.acme  IN  A   1.2.3.4

where 1.2.3.4 is the IP of the server where certbot will be run. This configuration directs any requests to *.acme.example.com to 1.2.3.4 where the plugin will respond with the relevant challenge.

Any server can be used as long as port 53 is available which means that a DNS server cannot be run at that particular IP at the same time.

You can then run certbot as follows:

certbot --non-interactive --agree-tos --email [email protected] certonly \
  --authenticator dns-standalone \
  --dns-standalone-address=1.2.3.4 \
  -d example.net -d '*.example.net'

Secondly, if you already run a DNS server you could configure it to forward all requests to *.acme.example.com to another IP/port instead where you would run certbot.

With Knot DNS you can use mod-dnsproxy:

remote:
  - id: certbot
    address: 127.0.0.1@5555

mod-dnsproxy:
  - id: certbot
    remote: certbot
    fallback: off

zone:
  - domain: acme.example.com
    module: mod-dnsproxy/certbot

Using this configuration all requests to *.acme.example.com are directed to 127.0.0.1 port 5555.

You can then run certbot as follows:

certbot --non-interactive --agree-tos --email [email protected] certonly \
  --authenticator dns-standalone \
  --dns-standalone-address=127.0.0.1 \
  --dns-standalone-port=5555 \
  -d example.net -d '*.example.net'

By default the plugin binds to all available interfaces. The validation usually takes less than a second.

To renew the certificates add certbot renew to crontab.

Usage with Docker

First, build the certbot image:

docker build -t certbot /path/to/certbot-dns-standalone/

Next, the certificate:

docker run -it --rm --name certbot \
  -v "/etc/letsencrypt:/etc/letsencrypt" \
  -v "/var/lib/letsencrypt:/var/lib/letsencrypt" \
  -p 8080:80 -p 1.2.3.4:53:53/tcp -p 1.2.3.4:53:53/udp \
  certbot certonly

where 1.2.3.4 is the IP address to use for responding the challenges. HTTP challenges should be directed to port 8080.

/etc/letsencrypt and /var/lib/letsencrypt need to be mapped to permanent storage.

Supported parameters

Parameters can be specified as --dns-standalone-PARAMETER=VALUE. For older certbot versions it should be --certbot-dns-standalone:dns-standalone-PARAMETER=VALUE.

Supported parameters are:

address -- IPv4 address to bind to, defaults to 0.0.0.0
ipv6-address -- IPv6 address to bind to, defaults to ::
port -- port to use, defaults to 53

The relevant parameters in /etc/letsencrypt/renewal/*.conf are dns_standalone_address, dns_standalone_port and dns_standalone_ipv6_address.

certbot-dns-standalone's Issues

Is it possible to define whitelist domains

Looks like anyone can add my domain and get their own wildcard certificate just by pointing their domains to my DNS server like

_acme-challenge IN CNAME evildomain.net.acme.mydomain.com.

How to do manual uninstallation?

After installing the plugin from the master branch with commands

setup.py build
setup.py install

How can I uninstall it afterwards ?

Is It me or has something changed?

I have used your plugin before successfully, I just tried to use it again and there was a Challenge failed for domain chat.knightirc.net

the command I issued was

certbot certonly --preferred-challenges dns --authenticator certbot-dns-standalone:dns-standalone --certbot-dns-standalone:dns-standalone-port=53 -d chat.knightirc.net

The following errors were reported by the server:

Domain: chat.knightirc.net
Type: dns
Detail: DNS problem: NXDOMAIN looking up TXT for
_acme-challenge.chat.knightirc.net - check that a DNS record exists
for this domain

port 53 open, and dig shows that acme is configured:

;; QUESTION SECTION:
;acme.knightirc.net. IN A

;; AUTHORITY SECTION:
acme.knightirc.net. 300 IN NS ns-acme.knightirc.net.

;; ADDITIONAL SECTION:
ns-acme.knightirc.net. 300 IN A 69.60.109.114

So have i goofed something up, or have letsencrypt changed something?

Certbot 1.10.0 released today with ECDSA support

Is it possible to issue ECDSA certs with certbot standalone?

Documentation needed

Is there any documentation for this plugin? We have a self-hosted BIND name server, and want to have more detailed guide for the config (not necessarily be a guide for BIND, but be more general so it could also benefit others)

Plugin is no longer supported?

No IPv6 support?

I ran server over IPv6 only and seems like the package does not listen on ::53.
Please consider adding IPv6 support.

Anything else to obey, did I miss/misinterprete something?

My current task is to get a wildcard certificate for "*.domain.tld" and I feel completely stuck.

I've set and propagated the _acme-challenge record:

host _acme-challenge.domain.tld

Processing…
_acme-challenge.domain.tld is an alias for lnx40.domain.tld.
lnx40.domain.tld has address 194.#.##.92

On lnx40.domain.tld certbot-dns-standalone is run with:

certbot certonly --dry-run -vvvv --config /etc/letsencrypt/cli.ini --preferred-challenges dns-01 --authenticator dns-standalone --dns-standalone-port=53 --dns-standalone-address=194.#.##.92 --doma

and always ends with:
…
Certbot failed to authenticate some domains (authenticator: dns-standalone). The Certificate Authority reported these problems:
Domain: domain.tld
Type: unauthorized
Detail: No TXT record found at _acme-challenge.domain.tld

Domain: domain.tld
Type: unauthorized
Detail: No TXT record found at _acme-challenge.domain.tld
…

It is verified that lnx40.domain.tld can rceive DNS queries from the internet. But Python and its messages are still a mystery for me. Any help is appreciated.

Can you make labeled release?

In essence the same as the earlier request. ( #4 )

on pypy the current version is tagged v.1.0.2

Python 2.7 (un)support

Hello,
I have encountered an issue with certbot-auto. It is running Python 2.7 and dns-standalone doesn't work. It throws many errors during the verification phase. I don't think they are important but I have attached them here.

Some challenges have failed.

IMPORTANT NOTES:
 - The following errors were reported by the server:

   Domain: metal.blep.cz
   Type:   dns
   Detail: DNS problem: query timed out looking up TXT for
   _acme-challenge.metal.blep.cz

   Domain: metal.blep.cz
   Type:   dns
   Detail: DNS problem: SERVFAIL looking up TXT for
   _acme-challenge.metal.blep.cz

Either way, if I create a blank venv with Python 3.5 or 3.6 and install certbot and certbot-dns-standalone via pip3 the errors are gone. So I suggest you remove Python 2.7 support on PyPI.

Sorry couldn't find another way to contact

Is there a way to automate this?? Or does it have to be manually ran?

certbot renew: Works for wildcard cert alone but not if called in crontab

Today I realized a fault during renewal of a bunch of certs. The error only occurs for our wildcard certificate when something like:

certbot renew -v --dry-run --config /etc/letsencrypt/cli.ini

is run or from /etc/crontab:

certbot renew.

If I use:

certbot certonly -v --dry-run --config /etc/letsencrypt/cli.ini --preferred-challenges dns-01 --authenticator dns-standalone --dns-standalone-port=53 --dns-standalone-address=#.#.#.# --domain "domain.tld,*.domain.tld"

from the commandline everything is carried out without any error (even without --dry-run).

To my dismay I'm completely unaware of Python and would like to ask for help in that matter. Googling around or searching here for issues could not help me so far. Please find attached some sompiled information and thank you in advance for any hint.

certbot-dns-standalone on Fedora 36

On Fedora 34 this was working, with just dnf install certbot pip and pip3 install certbot-dns-standalone. On Fedora 36 after the install the authenticator does not show up as those listed by certbot certonly. In non interactive mode an error is given.

certbot --non-interactive --agree-tos --email [email protected] certonly   --preferred-challenges dns --authenticator certbot-dns-standalone:dns-standalone   --certbot-dns-standalone:dns-standalone-address=0.0.0.0   --certbot-dns-standalone:dns-standalone-ipv6-address=::   --certbot-dns-standalone:dns-standalone-port=53   -d example.com
usage: 
  certbot [SUBCOMMAND] [options] [-d DOMAIN] [-d DOMAIN] ...

Certbot can obtain and install HTTPS/TLS/SSL certificates.  By default,
it will attempt to use a webserver both for obtaining and installing the
certificate.

Can you create a reference (tag) with a version number?

Stable version number, this would help support / inclusion from distributions.

SERVFAIL when looking up CAA records

When using the dns-standalone module for a full domain instead of a subdomain, it will also have to serve a CAA record or at least not return SERVFAIL or NOTIMP in order for Letsencrypt to be able to issue a certificate:
https://letsencrypt.org/docs/caa/
My domain does not have DNSSEC configured.

From the Letsencrypt logging: (replaced my domain with domain.com)

Confusing usage documentation

Document begins from statement that we have example.com domain for certbot service and example.net for certificate target domain.
Than we have this command:

certbot --non-interactive --agree-tos --email [email protected] certonly \ --preferred-challenges dns --authenticator dns-standalone \ --dns-standalone-address=1.2.3.4 \ -d example.com -d '*.example.com'

Shouldn't we have to use example.net instead?

Docker instructions?

Can you please give instructions on how to set this up with Docker? I'm still learning Docker but it seems like maybe this isn't Docker-ready?

I ran this:
docker build -t siilike\certbot-dns-standalone:latest github.com/siilike/certbot-dns-standalone
But it gave me an image that doesn't seem to expose port 53.

If this plugin is still supported, it would be great if you had a fully documented image on DockerHub for us to use.

Thank you!

Snap support

Would it be possible for this plugin to be released on snap? It seems the current certbot instructions prefer installing via snap, however, with this configuration it is not possible for certbot to find this plugin (or any other pip-installed plugin, for that matter).

There are some instructions here: https://eff-certbot.readthedocs.io/en/stable/contributing.html#writing-your-own-plugin-snap
