Can I have both at the same time? – if yes, in which order are they run?

It seems that the opening and closing of ports 80 and 443 did not run by the  
cronjob leading to a cert renewal failure. The renewal hook scripts did run however.  
After manually opening the ports and re-running the renewal cronjob did work though.

Using certbot-auto standalone, version 0.35.1 on Debian/Jessie

Regards,  
jf

The cronjob:

0 0,12 \* \* \* python -c ‘import random; import time; time.sleep(random.random() \* 3600)’ && /root/bin/certbot-auto renew --pre-hook “service aee stop” --post-hook “service aee start” --quiet

Please fill out the fields below so we can help you better. Note: you must provide your domain name to get help. Domain names for issued certificates are all made public in Certificate Transparency logs (e.g. [https://crt.sh/?q=example.com](https://crt.sh/?q=example.com)), so withholding your domain name here does not increase secrecy, but only makes it harder for us to provide help.

My domain is: dow172.bic.mni.mcgill.ca

I ran this command: /root/bin/certbot-auto renew --pre-hook “service aee stop” --post-hook “service aee start” --quiet

It produced this output:

My web server is (include version):

The operating system my web server runs on is (include version): Debian/Jessie

My hosting provider, if applicable, is:

I can login to a root shell on my machine (yes or no, or I don’t know): yes

I’m using a control panel to manage my site (no, or provide the name and version of the control panel): no

The version of my client is (e.g. output of `certbot --version` or `certbot-auto --version` if you’re using Certbot): 0.35.1

According to [User Guide — Certbot 2.7.0.dev0 documentation](https://certbot.eff.org/docs/using.html#renewing-certificates)

> Hooks specified in the command line, [configuration file](https://certbot.eff.org/docs/using.html#config-file), or [renewal configuration files](https://certbot.eff.org/docs/using.html#renewal-config-file) are run as usual after running all hooks in these directories.

So yes, you can have both, and the directory hooks run first. You can confirm this by putting an `echo` in the script files and another one in the command-line hooks; the output should be visible in the logs (and in the terminal, if you omit `--quiet`).

The hook files need to be executable, are they? They'll be silently ignored otherwise.

What does the log in `/var/log/letsencrypt` say?

The hooks files are executable by root, which is the user running the cronjob.

The log file is long, but here it is anyway:

OK, I edited the output before sending it for a slight obfuscation. You caught it.  
It’s really ‘service zmc\_aee’ start and stop.

Seems the hooks are indeed running, in the expected order.

Do you mean you manually ran the enable\_http script? Or did you manually open the ports some other way?

Well, that’s rather very embarassing!  
The pre and post scripts didcontain an error: they had the wrong network interfaces hard-coded in them!  
I would have assume that running ‘cerbot-auto renew --dry-run’ would have catch that.

Anyways, sorry to have wasted your time on an obvious mistake from my part!  
Thanks, jf
