Question regarding Acme and DDNS

johnpoz · Dec 13, 2023, 2:39 AM

@gregeeh if you have any questions just ask been doing it for years.. My gui cert is still good til 27, I have created it 2017.. This was before the browsers started complaining about long life certs..

I do need to get around to changing it, as want to completely move away from the local.lan domain have been using and use home.arpa - I have moved over some of my certs. But just haven't pulled the trigger on the webgui as of yet. Its working - not a lot of hurry to change it ;)

I have changed it on my unifi and nas because those certs were expiring..

Here is the cert on the webgui of pfsense, you can see it has multiple names I can use and also the IP, so even when accessed via IP, say my local dns was down.. Cert is still trusted.

@johnpoz - Followed all your steps. Imported into Firefox and all good :)

As for Chrome, imported into Trusted Root Certification Authorities as Personal did not work. Hope this was correct?

So, to create certificates for say my NAS and Unifi Controller, I would just repeat those steps making a CA and CERT for each. Correct?

Thanks again, for all your help. Much easier then using Acme Certificates.

Hello johnpoz

I have a question following your sentence. Why do you want to change this?

I copied your explanations (old but still valid) where you had used "local.lan" ... and now I see your message and I would very much like to understand the meaning of your remark.

I'm learning a lot here, THANK YOU!!!

I have the same question because I just can't get it. For access to my Pfsense it's all OK, but not for my "UCK_Gen2-Plus"!? Does it take time for the certificate to propagate?

No you only need the 1 CA, you can now create certs with that ca for any of your devices. And your browser will use them because it trusts the CA.

Oh I don't actually "need" too - but home.arpa is the new recommended domain to use locally..

https://datatracker.ietf.org/doc/html/rfc8375.html
Special-Use Domain 'home.arpa.'

I do believe pfsense now defaults to that.. There is no "need" to move away from my local.lan domain I could continue to use it - but there is no reason I shouldn't use the home.arpa so at some point I will make sure everything locally is using it..

The controller is a pita to get to use new certs.. I have no idea why they don't make it simple to change out via the gui, like my nas was, or even my printer. There are instructions out there to do it..

Here are my notes for changing it on the unifi controller.

From the CA, have these files available:ca.cert.pem (CA cert)server.domain.net.cert.pem (server cert)server.domain.net.key.pem (server key)

copy them to the unifi controller.

delete the old keystore and restart unifi to create an empty keystore:sudo rm /var/lib/unifi/keystore sudo service unifi restart

Create a central file to upload to the keystore:openssl pkcs12 -export -in server.domain.net.cert.pem -inkey server.domain.net.key.pem -certfile ca.cert.pem -out unifi.p12 -name unifi -password pass:aircontrolenterprise

This gives you the file unifi.p12.

Now import this into the unifi keystore:keytool -importkeystore -srckeystore unifi.p12 -srcstoretype PKCS12 -srcstorepass aircontrolenterprise -destkeystore /usr/lib/unifi/data/keystore -storepass aircontrolenterprise

Restart unifi sudo service unifi restart

And we're good to go.

more info
keytool -list -keystore data/keystore -v

keytool error: java.io.IOException: keystore password was incorrect
when using Openssl to export, add -legacy so openssl v3 will revert back to legacy mode, and then keytool was able to import.
openssl pkcs12 -export -legacy

Thanks for your explanation, it's going to go beyond my skills and I don't want to break anything on this unify controller ... it's complicated enough (for me) with Unify when there's a new camera, for example, and it's not seen ....

Sure as long as your browser trusts the CA is all that matters.
