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.

What DDNS providers you guys recommend? (lemmy.ml)

I'm new to self-hosting. All I did so far was install Ubuntu Server, enable SSH and tried setting up DuckDNS, which I could not set up automatic update of my IP following the documentation, neither updating manually through the website, which even though seems to be changed, when I ssh the domain, I get the initial IP

Anyone using DuckDNS? Is it working properly for you guys? Did I just mess something up?

What other DDNS providers would you recommend me?

Same. I have a router with OPNsense. In the "Dynamic DNS" section I create a "Custom" service with the DynDNS2 protocol. I type in update.dedyn.io as the server address. You need to also get an api key from the desec.io web panel that you input into the username and password fields.

Now everytime the router's WAN ip changes it automatically edits the DNS zone. So instead of going "your server -> DDNS provider -> DNS CNAME record" it's just "your server -> DNS A record"

I also have a separate token for my web proxy (traefik) so that it can edit the DNS records to get let's encrypt certificates through dns challenge as you describe.

As for the desec signups in my case one DNS zone was no problem, but for a second one I needed to e-mail them:

Hello, would it be possible for my newly created account to get one more domain on the account please? I have two personal domains and it would be great if I could keep them both under deSEC

Hi [me], Sure! The limit is mostly there to remind users to enable DNSSEC, but it looks like you're already doing that (at your old provider).

They asked me to (voluntarily) donate, which I did too.
