Since you run already OpenWrt, you can check out https://openwrt.org/docs/guide-user/services/ddns/client

There is a list on this page of compatible services. If you don't want to use one more service (DNS), you can use a domain registrar with an API (like porkbun) and find online tools that work with that.

Be aware of the risks of hosting your websites publicly from home, make sure to run them in very isolated environments. Having your VPS compromised is bad, but having your home network compromised is much worse!

Fair question. What I meant is that suggesting that would have made the whole post 10 lines long and not worth doing. So I avoided such suggestions that completely change the threat model.

It's not useless to avoid a good security posture (although you might have concerns of a monopoly gatekeeping the internet, TLS traffic inspection privacy concerns etc.), on the contrary makes everything I have written about here redundant (+ provide more, like DDoS protection) as you are outsourcing the security controls.

Yep I agree. Especially looking at all the usernames that are tried. I do the same and the only risk come from SSH vulnerabilities. Since nobody would burn a 0-day for SSH (priceless) on my server, unattended upgrades solve this problem too for the most part.

That is basically the essence of this post too! Except crowdsec is used to do what fail2ban does + some light form of WAF (without spinning another machine - which is not strictly needed for a WAF, you can use owasp modsecurity-ready proxies).

Thanks! I did mention this briefly, although I belong to the school that "since I am anyway banning IPs that fail authentication a few times, it's not worth changing the port". I think that it's a valid thing especially if you ingest logs somewhere, but if you do don't choose 2222! I have added a link to shodan in the post, which shows that almost everybody who changes port, changes to 2222!

Yes, pretty much that. Plus some configuration might be easier with a DNS hosting. But the main benefit is decoupling domain and DNS for easier change.

Been there...

I thought my API keys were expired, I regenerated them, changed a couple of things, checked all API calls to see if they changed API itself...then I searched the exact error and found out.

For such a breaking change to the API, was it hard to drop an email to every account not meeting the damn "requirements" with an API call performed in the last x months, to alert of the change?

Yep, I like bunny in fact. It didn't have all the features I needed back then, but it's a very good product, I heard very good things.

I also agree about the pricing. I ended up not using desec.io, but if I did, I would have probably set a 1-2 Euros recurring donation, as I feel that's a totally acceptable price.

As for why people use GoDaddy well... I feel personally attacked as that's exactly how I ended up there, when I didn't know better.

I also use porkbun, their API is not a masterpiece but it works and allows you to get, set and update records. In fact their API is now supported by some of the common ddns scripts out there.

I think I used it in the past. Is the one where every X months you need to go the the console and confirm the domain is still used, right?

I think nowadays there are better options (incl. Free) with less maintenance and more flexibility

That's a very interesting gotcha. They don't seem to support address ranges either. Unless once you add the whitelist the requests still work from any address (their documentation is ambiguous). This is even more confusing.

Desec.io is a good option. To be honest using cloudflare just for DNS is completely OK. It's not a service that allows spying on you or consolidates their monopoly.
