Selfhosted

A place to share alternatives to popular online services that can be self-hosted without giving up privacy or locking you into a service you don't control.

Rules:

  1. Be civil: we're here to support and learn from one another. Insults won't be tolerated. Flame wars are frowned upon.

  2. No spam posting.

  3. Posts have to be centered around self-hosting. There are other communities for discussing hardware or home computing. If it's not obvious why your post topic revolves around selfhosting, please include details to make it clear.

  4. Don't duplicate the full text of your blog or github here. Just post the link for folks to click.

  5. Submission headline should match the article title (don’t cherry-pick information from the title to fit your agenda).

  6. No trolling.

  7. No low-effort posts. This is subjective and will largely be determined by the community member reports.

Let’s Encrypt will be reducing the validity period of the certificates we issue. We currently issue certificates valid for 90 days, which will be cut in half to 45 days by 2028.
This change is being made along with the rest of the industry, as required by the CA/Browser Forum Baseline Requirements, which set the technical requirements that we must follow. All publicly-trusted Certificate Authorities like Let’s Encrypt will be making similar changes. Reducing how long certificates are valid for helps improve the security of the internet, by limiting the scope of compromise, and making certificate revocation technologies more efficient.

I agree, but it's impossible to convince my less tech savy roommates and friends to let me install a root certificate. "That sounds like i could read all their private messages", lol. Just let me have my certificate for https in my local net. I don't need to be "even more" secure. I get that that's necessary for public services, but surely not for local selfhosting. I don't even have a port open other than wireguard. And i would not even care "if a roommate hacks/gets access to a guests voice commands for home assistant." (Not complaining at you but at this trend. I do think my use case is valid)

You are gonna laugh if i tell you how i partly automated this workaround. A script changes the (dyn) dns entries of all subdomains to point to my public server in a datacenter. There, it ssh's in and requests the certificates with certbot. Then, it restores the dns entries and downloads and installs the certificates in the local net. Still requires manual supervision and sometimes intervention. My domains do not support automated dnssec. I don't have time to secure my local net enough to feel good about opening ports. If all certificate lifetimes get shorter, i'll either have to switch my domain provider or give up selfhosting for other people.

Allowing a certificate without proper validation for local only networks is a terrible, terrible idea. I could super easily use this as a loophole to set up a honeypot public free wi-fi, redirect all traffic through a reverse proxy and man-in-the-middle every single HTTPS connection, effectively allowing me to harvest everyone's passwords in a really quick and easy way.

Just use DNS verification. It's not that hard.

I've had dns-01 validation running for a while now. It's not difficult, just a paradigm shift. I spent a minute just now looking for a concise how-to for you and didn't find one, so I suppose I'll have to write it.

I'll bookmark this comment so I can find you once I've done that.
