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.

The "safest" way of self hosting (feddit.uk)

Hello peoples,

I am looking for tips on how to make my self-hosted setup as safe as possible.

Some background: I started self-hosting some services about a year ago, using an old lenovo thin client. It's plenty powerful for what I'm asking it to do, and it's not too loud. Hardware wise I am not expecting to change things up any time soon.

I am not expecting anyone to take the time to baby me through the process, I will be more than happy with some links to good articles and the like. My main problem is that there's so much information out there, I just don't know where to start or what to trust.

Anyways, thank you for reading.

It's true that you shouldn't open ports to the internet. If you still want your services to be accessible from outside the local network you can install a wireguard server on your thin client that has access to the services you want. And if you really want to harden it you can restrict wireguard clients from ssh and other admin things.

You will need to open one port on the router to your wireguard server though. Wireguard is UDP though and ignores packages without an established connection, so attackers will not even know there is an open port on your router.

Edit: tailscale and zerotier are good external solutions to this as well without needing to open a port at all.
