Hey guys, I was happily running 44 docker containers for a while on Debian host. Today I tried to add a new service (uptime-kuma) using portainer stacks, but I got this error:

Error response from daemon: could not find an available, non-overlapping IPv4 address pool among the defaults to assign to the network

Quick google led me to this link where I found possible problem with max number of docker networks. I did docker network prune, it removed 5 networks that were not in use and viola, uptime-kuma is working now!

Am I reaching the limit? What to do if I need 10 more services on the same host? I bet I saw some people in this community running many more services

This is a followup of my last post where I was looking for a solution to our problem with smell coming from the kitchen hood (extractor) when neighobour is cooking. I got many good suggestions, but @Finlsolo963 pointed me to Shut-off Damper with motor that looks like perfect fit. I hope it can stop the smell completely in closed position and open automatically when we start using hood.

I was looking at this Damper

I could use Shelly Plus Plug S to detect power usage of the hood which trigers Shelly 2.5 to open Damper. After turning off the hood, power will go down and automation would triger another channel of Shelly 2.5 to close the Damper.

What do you think about the setup? Is there any better hardware you would suggest? I dont mind spending more for beter sealing when Damper is closed. I like the one from the link mostly because its 220V and I could use shelly relays which seems super simple to implement. I already own Shelly Plug S that I could use, but its not a must. Im also opet to zigbee devices.

Bonus question: what would happen if something goes wrong and both channels of Shelly 2.5 triger at the same time? It would be like pressing Open and Close buttons at the same time.

Thanks in advance

Hey guys Im a proud owner of Delonghi Magnifica S automatic espresso machine for 6 months now. Our water is super hard with loads of scale and I have been cleaning (descaling) machine with Delonghi EcoDecalc, but friend recommends this one (much cheaper):

Is this safe to use? It says it contains citric, lactic and malic acid. It also says to use 50 ml on 500 ml of water while Delonghi EcoDecalc should be 100 ml on 1700 ml (I think) of water. Its almost 2x difference and I was thinking if acids are simmilar I should use 100 ml of acid for full tank anyway.

We abuse our machine by making loads of coffe and tea. With scale settings on max we get descaling alarm every 3-4 weeks. It used to be on medium settings, but machine almost clogged completely once...so thats why max settings. Delonghi liquid is not cheap, but dont want to take any risk for 30€ a year. On the other hand, I dont want to pay 10€ for a 2-3€ product just because it says Delonghi on the bottle.

What do you use for your machine? How often do you descale?

Hey peeps, I moved to a new appartment and my kitchen hood is connected to the same pipe (chimney) as hood from appartment below. The issue is smell coming from our hood when neighbour is cooking.

I was thinking about some kind of sensor (air flow or humidity or smell?) that can detect when neighbour is cooking and then HA would turn on our hood at the lowest speed.

I have no clue what kind of sensor would be suitable. I also need to figure out how to start our hood with HA (hacking with relay or buying some kind of smart kitchen hood is acceptable). Our kitchen hood is just regular Faber with 4 position switch for selecting fan speed.

Anyone have idea how to solve that issue? What sensor would be best for that?

Note that I have already installed 1-way valve (not sure whats the correct english word) and 3 different filters, but still sucks

Edit: I got some things going on, cant replay to all comments today and probbly tomorrow. Thank you all for input, Ill come back asap

I have some Bitcoin and Ethereum on Coinbase since 2018. Coinbase never failed me, but they ask for more and more personal details. Last requests made me look for alternatives. I read wasabi is one of the best privacy focused wallets, but what do you use? Im not trying to hide anything from goverment or anything like that, I just want safe place for coins that doesnt feel like someone is tracking every single step I make

Edit: made sentence more clear

Hello selfhosters,

I recently moved to a new place with faster internet (320/130 Mbps) and now I see that VPN is limiting my torrent speed.

I was testing multiple AirVPN (wireguard) servers and I'm getting 80-120 Mbps on speedtest-cli, but in torrents it goes bit higher to about 180-200 Mbps. I usually use it trought gluetun container, but was also testing with eddie-cli and I get pretty much the same results.

I was reading that people get 600 Mbps and even 1+ Gbps on AirVPN. What is your experience? If this is AirVPN limit, what would you suggest as alternative with port forwarding to saturate my bandwidth? I can live with these speeds, just want to check if there is better alternative or something missconfigured on my side.

Cheers

I know we had posts like this before, but Immich deserves 👏

One more update, one less container, the best Google Photos alternative, its just amazing!!

Don't forget to edit your docker-compose before updating

He guys,

after upgrading to Nextcloud 27 I noticed some errors in Security & setup warnings. I fixed all of them, but don't know what to do with this one. I've read documentation, but still don't know what to do. How to fix this or should I just ignore it?

I'm running lsio docker container, Nextcloud version 27.1.4

Hello selfhosters,

I need recommendation for cheap VPS that I will use to host gramps only. Gramps is selfhosted app for building family tree.

I tested gramps in docker container on my home server and its awesome, check it out. My home server is not open to public (accessing it using wireguard only) and I would like to give access to some family members (3-4) for gramps. I thought its best to pay for cheap VPS and run gramps only to avoid any security issues on my home network.

I believe performance and storage requirements fit in any cheapest model, but not sure which VPS is the easiest to setup. I have my own domain from porkbun, but I have never set SSL certs properly before and I have never used VPS. I see this as a great opportunity to learn, but also to make some family members happy <3

I'm eying servercheap.com and it says in description "1 IPv4", but then it offers "Add'l Ipv4 Addresses" for 9$. I'm bit lost here and I'm not even sure do I need IPv4 address. Maybe I can run duckdns or ddclient to avoid additional cost?

How is your experience with servercheap? Is there anything better for similar price?

Also, any tips for building server like that are appreciated. I was thinking Debian 11 + gramps in docker container since I'm familiar with that setup.

Cheers

Hey guys,

how to find out why Sonarr can't send test message via Gotify? I'm getting "Unable to send test message " in logs. I'm using discord notifications with no problem.

I tried moving Gotify in the same docker stack as my arr apps. Gotify is running behind gluetun just to make it available on the same network (maybe not necessary?). I have opened port for Gotify (8099) in UFW. I can send msg to Gotify using Android phone.

docker-compose

SONAR LOGS

While discord is working fine, I'm trying to move away from it. If there is any alternative to Gotify please let me know. I'm running docker containers on Debian host.

thank you

edit: If I try to open Sonarr console and do curl -v http://192.168.100.40:8099/message?token=AOhF2MthB0V1IhV its just hanging and then console closes (using protainer)

So basically what title says.

Im using 2FA with google authenticator for multiple accounts. What if my phone gets stolen? Can I have some kind of backup? Or maybe sync with some self hosted service?

Bonus question: what 2FA should I use instead of google?

[SOLVED] 12 TB disk finally arrived, I used clonezilla. Using advanced settings and -k1 (everything else left as default) made exact disk with more storage. I just replaced disks, powered on and everything is up and running! Ty all ❤️

Hello selfhosters,

I'm running home server DIY PC with *arr stack in docker containers and its working surprisingly well. The problem I have is not enough storage for my needs so I ordered a new HDD.

At the moment I have OS (Debian) and some (config) volumes on one SSD while media library is on another SSD. I'd like to move only media library from old to a new HDD and stop using the old one.

What is the best way to move all files (including hard links?) to a new drive? Can I just copy files with same folder structure and then modify my docker-compose.yaml to point to a new HDD? Is backup and restore of *arr apps necessary? Is there any way to grab all torrent files from qbittorrent (or another way of backup?

Folder structure I have now:

System SSD:

• SSD1/config/sonarr
• SSD1/config/radarr
• SSD1/config/qbittorrent

Data SSD:

• SSD2/data/media/tv
• SSD2/data/media/movies
• SSD2/data/torrent/tv
• SSD2/data/torrent/movies

THX!
