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.
One of my home servers was popped once, they stuck a new MOTD on there to let me know how foolish I was and I haven’t made that mistake since. So… yay greyhat?
All you have to do to avoid this is just not open any ports except one for something like wireguard, and only access your network using it externally, and you will never have this problem.
Exactly. It wasnt on purpose either. I thought there was an additional layer of security, gullible as I was 5 yrs ago. They made it seem like there was.

One of my fears of starting up my homelab.

Gotta have a firewall that closely resembles swiss cheese.
