Certbot-ssh - Certbot SSH authenticator plugin
Certbot-ssh is a plugin for the Certbot ACME client that performs HTTP01 challenge validation on a remote computer through a SSH connection.
The Certbot client assumes it runs on the machine that serves web pages for the requested domain.
That is not always desirable or even possible.
The manual authenticator (
--manual) allows to run the client on a
separate machine; it is then up to the system administrator to make sure
the web server responds appropriately to the HTTP01 challenge, by
putting a specific value into a specific file under the
.well-known/acme-challenge directory of the web server. This can be
quite tedious, especially if you require a cert for many domains.
This plugin provides an automatized version of the “manual” process. Upon receiving the challenge data from the ACME server, it will execute a script on a remote machine through a SSH connexion, and feed it with the challenge data. It is then up to the script to write the challenge tokens at the appropriate place.
A sample script is provided. This
script assumes the webroot of a requested domain is under a
/var/www/domain directory; you will probably need to adjust it
according to the layout of your own web server.
Install the package:
$ python setup.py install --user
acme-challenge.sh script if needed, then upload it to your
server. Put it somewhere in the
PATH of the user account you use for
SSH connection. Remove the
.sh extension and make sure the script is
Then you may call Certbot:
certbot certonly \ --authenticator incenp.certbot.ssh:ssh \ --incenp.certbot.ssh:ssh-server firstname.lastname@example.org \ ...
Note that the client will attempt to write to some system directories on
the local machine (
/var/lib/letsencrypt). Use the
--logs-dir options to specify other
directories if you want to run the client from a non-root account.
