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.
I don’t run Pi-hole but quickly peeking into the container (docker run -it --rm --entrypoint /bin/sh pihole/pihole:latest) the folder and files belong to root with the permissions being 755 for the folder and 644 for the files.
chmod 700 most likely killed Pi-hole because a service that is not running as root will be accessing those config files and you removed their read access.
Also, I’m with the guys above. Never chmod 777 anything, period. In 99.9% of cases there’s a better way.

Well I’m running Pihole in docker and don’t have 777 on anything.
Good for you. What permissions do you have on etc/dnsmasq.d if I may ask?

chmod 777anything, period. In 99.9% of cases there’s a better way.Thanks for checking that. I will change the permissions accordingly and restart pihole to check if it works. Probably later today.
