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.

My stupidity saved me from being hacked today! (lemmy.giftedmc.com)

I know, I know, clickbaity title but in a way it did. It also brought in the situation in the first place but I'm just going to deliberately ignore that. Quick recap:

  1. I came home at 3pm from the city, my internet at home didnt work.
  2. checked multiple devices, phones worked out of wifi, I figured I need to restart the router
  3. I login to the router and it responds totally normal but my local network doesnt. (Its always dns, I know)
  4. I check the router log and see 100s of login attempts over the past couple of days.
  5. I panic and pull the plug, try to get into my server by installing an old monitor, works, many errors about dns
  6. Wife googles with her phone, seems I had https login from outside on and someone found the correct port, its disabled now
  7. Obviously, local network still down, I replug everything and ssh into the server which runs pihole as dns
  8. pihole wont start dns, whatever I do
  9. I use history and find I "chmod 700"ed the dns mask directory instead of putting it in a docker volume...
  10. I check the pihole.log, nothing
  11. I check the FTL log, there is the issue
  12. I return it to 777, everything is hunky dory again.

Now I feel very stupid but I found a very dangerous mistake by having my lan fail due to a less dangerous mistake so I'll take this as a win.

Thanks for reading and have a good day! I hope this helps someone at some day.

There was an option that I had enabled years before and forgotten so yes, I didnt know but it was, on some obscure port.

And yes, pihole in docker makes its files be 777 which is pretty disgusting, I know. Thats why I tried to make it 700 and broke my whole network.

Doubt. You probably need to set the file owners in your volume to the same user running in the container.

I think you are still learning... What you say doesn't make sense, so I think you may have misunderstood what happened.
