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

Wipe and start fresh
Are you joking? Why would I start fresh?
Because you don’t have a way to know what’s been compromised. Take your data only and make sure to verify nothings been tampered with.
Trust me it will be better in the long run.
Yeah, I dont feel like setting up a whole cloud infrastructure on a hunch. I‘m running like 15 different services and they are all compartmentalized. It would take weeks to reset all this. So far nobody got anywhere from what I can see.
Just be careful
Wow, a lot of people would set up a new server because of intrusion attempts in a log i guess. If I did that in a job I‘d get fired for doing nothing else but resetting everything every week.
As an admin, you have to keep the CTO from using „master“ or „admin“ as the ssh password on a production server. Just so you know what level of stupidity makes the big bucks out there.
777? Bruh just set the owner?
The owner was root and still is. I changed from 777 to 700 which broke everything. Sorry if that wasnt clear. I will switch to a docker volume to avoid having this crap in my hone folder in the future.

I’ve adopted a policy of always ebetering my password wrong the first time.
It started by accident.
