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 a basic question. So if I have a pihole, do I just need to update the Raspberry Pi software, along with updating pihole software to resolve the insecurities? Or do I need to change the DNS settings of the pihole?

If you use a third-party's DNS server (such as Cloudflare, Quad9 or Google) as your upstream DNS server, you only have to update PiHole.

If you have set up your own upstream DNS server using a DNS resolver like unbound or Bind9, update it as well as your PiHole.
