Cert update dates

jimp

Check your ACME certificate entry, look in the Actions list and check for, or add, a set to run /etc/rc.restart_webgui as an enabled shell command.

Without that, the GUI wouldn't be restarted after renewing the certificate. Also assuming your cron job box is checked on the ACME general settings tab.

@jimp Thanks! I did not have it added.

@jimp one more question - is there a simple way to test that email works from letsencrypt ? I don't think I got any before Acme updated certificates and now have to wait for 60 days...

jimp

No test I'm aware of. I know they still do it, though, as I received an e-mail from them over the weekend. I forgot to check the cron box on one of my lab systems.

Oh, yes !
Get some certs from the Staging server. As soon as you get one of them, you'll be mail stormed after de delay.
I never received a mail that told me that I was late to renew a 'real' certificate. All my certs just renew by itself after 60 days - or the period I choose, which is generally somewhat less then 60 days.

Be aware that you can 'redo' your cert manually 5 times a week - just hit the renew button.

You could also renew from the command line : just run what the cron runs :

/usr/local/pkg/acme/acme_command.sh renewall

You'll see that it comes back with

....
Renewal number of days not yet reached.

So, force it like this :

/usr/local/pkg/acme/acme_command.sh  renewall -force

You'll be seeing a boat-load of lines on the screen, and finally, after the DNS delay etc, you obtain a new cert.
(don't forget to restart all services that use the certificate- as you already figured out)

Strange. It tries to delete
brit-hotel-fumel.netnsupdate.key
But the file is really called :
brit-hotel-fumel.netnsupdate_acme-challenge.brit-hotel-fumel.net.key

Looks like the "_acme-challenge.brit-hotel-fumel.net" part is missing when it constructs the file to delete.
Minor issue actually.

@jimp : can you confirm ?

I was looking for a simple way to either trigger email or see what certificates associated with my email.

Thanks for details !

That is not a ACME cert

jimp

To help with some of this confusion, ACME 0.5.7, which I just committed a few minutes ago, now uses RFC 2822 format dates to show the last renewal. This makes it consistent with the dates shown on other certificate-related pages.

chudak

@jimp Thanks looks good !

chudak

@johnpoz

I am still not 100% sure what's going on with update dates.
So I am a new user of ACME and like it a lot!

Last time I manually updated certificates were April 7th

I expected to start seeing emails 20 days before expiration sometime around 10th of July.

I actually saw that certificates were renewed yesterday June 7th.

What am I missing ?

Thx

Derelict

It was automatically-renewed like it was supposed to be.

Certbot runs every day. It checks the dates. If it needs to be renewed it runs the process. If everything works you have a refreshed cert.

I get that, but why I did not get any emails ?

@chudak said in Cert update dates:

From who ?
acme works has the FreeBSD/Linux mentality : no news is good news.
There isn't a checkbox that states : "send me a mail" neither.
Although the question was asked before.

When you visit your setup, and the cert is 3 or 4 week, just hit the Renew yourself, and observer the process.
When no errors, and you don't break things afterwards, renewing will just go fine in the future.

edit : or : help yourself : write a small shell script that collects some data , activate it in the Action list and our done.

/usr/local/pkg/acme/acme.sh --home /tmp/acme/[your-domain]/ --list

to see actual cert details.

Derelict

Emails from where?

jimp

If you put your e-mail on the ACME key then Let's Encrypt (NOT pfSense/the firewall/etc) will send you an e-mail when it is close to expiring, but that only triggers if it's not renewed before the time they warn you.

Since the ACME package checks every day to see if it needs renewed, it gets renewed before that e-mail warning would fire off.

The firewall won't e-mail you anything about the certificates, but it makes entries in the main system log. If you have a central logging system you could have it flag those messages and alert you when things happen.

chudak

@jimp

Hmm

letsencrypt has 90 days cycle, no ?

why then I see this (using the script by @Gertjan ):

/usr/local/pkg/acme/acme.sh --home /tmp/acme/XXXYYY/ --list
Main_Domain      KeyLength  SAN_Domains  Created                       Renew
XXXYYY  ""         no           Fri Jun  7 10:16:07 UTC 2019  Tue Aug  6 10:16:07 UTC 2019

renew in 60 days ?

Also you say "If you have a central logging system you could have it flag those messages and alert you when things happen."

Any example of you do to flag messages ?

Thx

jimp

@chudak said in Cert update dates:

The certificates expire in 90 days.

@chudak said in Cert update dates:

renew in 60 days ?

It renews then so that if there is a failure, you have time to fix the problem.

@chudak said in Cert update dates:

No, that's all up to your logging/alerting/NMS system.

chudak

@jimp Ok cool, sounds like all is in order.

I will wait for emails to be sent then.

Thx!

Gertjan

@chudak said in Cert update dates:

Check your own settings of your cert : bottom of the page :

You see the last renewal date.
And the time - default 60 days - when it gets renewed.

See my edit above how to implement a small shell script that sends a mail as an Action script.

chudak

@Gertjan

Makes sense, changed to 90 days, and added the script to Certificate options Actions list (not sure if it will send email, but will be seeing in the logs for sure)

Thx!
