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.

Blocked that hard-coded google dns garbage.

I have a firewall rule to dst-nat any outgoing DNS requests not coming from piHole back to the piHole server. That way all devices on the LAN are forced to use piHole for DNS and can't bypass it. I don't have an OPNSense firewall but I would think it should be able to do that as well.

No, you can block ads with a pihole. This is because Roku hard codes its dns server as 8.8.8.8. Pihole doesn’t handle IP addresses, only DNS.

Interesting. I set an adblocking dns via DHCP and, as far as I know, the Roku respects it. Ads are blocked and I can see it failing to delivery telemetry in my dns logs (most persistent thing on the network).

I set a rule to catch outside dns to see if anything, the roku included, has been misbehaving.

Pihole blocks the basics for Roku. Things like logs ads etc. but there’s a lot more telemetry that they’re collecting. Here’s a hackernews thread about the topic and the associated article it references.
