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.

(Sorry if this is too off-topic:) ISPs seem designed to funnel people to capitalist cloud services, or at least I feel like that. And it endlessly frustrates me.

The reason is even though IPv6 addresses are widely available (unlike IPv4), most ISPs won't allow consumers to request a static rather than a dynamic IPv6 prefix along with a couple of IPv6 reverse DNS entries.

Instead, this functionality is gatekept behind expensive premium or even business contracts, in many cases even requiring legal paperwork proving you have a registered business, so that the common user is completely unable to self-host e.g. a fully functional IPv6-only mail server with reverse DNS, even if they wanted to.

The common workaround is to suck up to the cloud, and rent a VPS, or some other foreign controlled machine that can be easily intercepted and messed with, and where the service can be surveilled better by big money.

I'm posting this since I hope more people will realize that this is going on, and both complain to their ISPs, but most notably to regulatory bodies and to generally spread the word. If we want true digital autonomy to be more common, I feel like this needs to be fixed for consumer landline contracts.

Or did I miss something that makes this make sense outside of a big money capitalist angle?

If you have control over at least the root of your network you can totally get away with hosting in a dynamic pub ip. You just need to set up dynamicdns. There are other ways of handling this specific issue too. You can always go to a colocation and set up a server there if you want. You could also create your own reverse proxy tunnel in a place that is public then forward it. There are lots of work arounds really. Yeah, it sucks that American ISPs generally don’t support ipv6 but there are totally ways to work around it all.

What really gets me up in arms is when they advertise gigabit connections or 500mb speeds only to limit upload to 20mb/s. That is where they are actively inhibiting self hosting communities.

Even in an ideal DNS setup, you're probably going to have downtimes whenever your dynamic IP changes. If only because some ISPs even force-disconnect you after a while to change your address.

I mean I’ll be real. Sure in some circumstances that could be an annoyance for 15 seconds for some software that might rely on a session whenever your ip changes like once a month if that. A rotating ip is probably one of the easiest things to work around amongst the plethora of challenges that ISPs present for those who want to self host.

I mean just take a look at what is involved if you are in a situation where cg-nat is implemented. You legitimately have no control over the root of your network at that point. I have that issue in particular with what is essentially a mobile hotspot as my failover for when my fiber fails. That being said I had to architect it in a way that took that took cg-nat into consideration. If I hadn’t then when fiber fails it would take down my services as a whole anyway.

My point is that those challenges have workarounds, you can solve those issues relatively easily and they even present a level of security. Where it is actively malicious is with restrictions to capacity such as upload limits in which they to a degree lie about their speeds and capacity. The terms of service stuff is just flat out awful too.

Some ISPs require changes ever 24 hours and will disconnect you if needed. Also, if you set DNS to cache such a short amount of time that you can react to that in 5 minutes, you will incur way more DNS traffic which can become a problem when your site is busier. Also, even if your DNS TTL is set to a super short value, a web search suggests to me in practice there will likely be downstream clients and networks that ignore it and won't really update in such a short time frame.

What ISP are you referring to? I have genuinely never heard of an isp that takes 24 hours to rotate your IP. Also utilizing dynamicdns is not going to incur more dns traffic? Dynamic DNS updates your dns provider from a system on your local network that your pub ip has changed then your provider will start sending traffic to the new ip. Propagation used to take a while but I haven’t experienced propagation wait times of over 10 minutes in years. This all being said dynamic DNS isn’t exactly the most elegant solution. It is just one of the simplest that I mentioned. There are significantly better options overall that completely take the requirement of a static pubip completely out of the equation and can be built using all free open source tools relatively easily.

It causes way more traffic for the DNS server to use a shorter TTL, so yes, it does incur more DNS traffic. In Germany some providers will disconnect you regularly if you stay connected for too long.
