Hiya, so I have a spear RaspberryPI 4b, and want to selfhosted HomeassistantOS on it, heard there were some advantages of running the full OS and not just the docker container. However I currently don’t have a casing for it....
Guessing it is more a habit from back in time when ssl certification wasn’t common. Panic of MITM attacks, friends sharing their trusted access to other friends, etc. all contributed to my actual status of paranoia.
Don’t make me reconsider my cybersec approach ;)
I used VMs some time ago but never managed to look deeper into separation of bare metal vs VMs. Hence I can’t assess this reasonably.
Docker got me interested when it started and after discovering its networking capabilities I never looked back.
Basically I’m trying to minimize the possibility that by intercepting one dockerized service the attacker is able to start interacting with all devices. And I have lots of devices because of a fully automated house. ;) My paranoia will ensure the constant growth of privacy and security :)
Looking for a self-hosted home audio system, something like Sonos where you can play music in different zones/rooms and control it from a phone or tablet. Not sure on speakers, maybe something running off of raspberry pi’s or just standalone speakers if that would work. Anyone doing something like this?
Personally I use Raspi 2 and Zero for that purpose. HATS for digital connection or if you want connecting speakers directly consider AMP2 HAT.
Homeassistant controls grouping, volume etc.
If I’m understanding you correctly, you could make use of a shell script for this. Use WGET to download lists, then combine them into a single large file, and finally create a new file with no duplicates by using “awk ‘!visited[$0]++’”
It depends a bit on what you want to accomplish, the threat model, the devices in use, and other topics. I think this is a good read: avoidthehack.com/best-pihole-blocklists
Beets is my favorite tagger since I prefer CLI. Match making policy can be adjusted and discogs plugin can be added I recommend the folder structure /artist/album/track
I’ve had a home server for years, at first using Windows Server, then Unraid, and now using Ubuntu server. I’ve long known that I should keep a close eye on my spinning rust, but I never really knew the best way to have that monitoring quietly automated in the background, only sending me a message when something bad shows...
SMART value monitoring helped me finding faulty drives, not only once. And drives are tested before adding to a production system.
Certainly system drives are separate from data drives. The latter can be perfectly monitored by SMART values.
I think you can’t track data corruption either because you will find out only when it occurred. Same is valid for SMART values as you correctly state. I believe it is a mix of using zfs, ECC and SMART monitoring. phoenixnap.com/blog/data-corruption
Thanks for clarifying the intricacies connected to SMART monitoring.
I use some batch scripts in my proxmox installation. They are in cron.hourly and daily checking for virus and ram/CPU load of my LXC containers. An email is send on condition....
I set up custom bash scripts collecting information (df, docker json, smartCTL etc) Either parse existing json info or assemble json strings and push it to Homeassistant REST api (cron) In Homeassistant data is turned into sensors and displayed. HA sends messages of sensors fail.
Info served in HA:
HDD/SSD (size, smartCTL errors, spin up/down, temperature etc)
Availability/health of docker services
CPU usage/RAM/temperature
Network interface/throughput/speed/connections
fail2ban jails
Trying to keep my servers as barebones as possible. Additional services/apps put strain on CPU/RAM etc. Found out most of data necessary for monitoring is either available (docker json, smartCTL json) or can be easily caught, e.g.
df -Pht ext4 | tail -n +2 | awk '{ print $1}
It was fun learning and defining what must be monitored or not, and building a custom interface in HA.

AdGuard/PiHole Blocklists merge duplicates
Does anyone know of any off the shelf tool (online or offline) to find duplicates in several DNS blocklists and merge them into one?...
Users of PiHole/AdGuard/Blocky, what blocklists are you using?
EDIT: Thanks so much guys! This was really helpful, and I didn’t imagine so many would help out!...
