does anyone have a good suggestion for running a mail server on my nixos box?

I self hosted an instance at is.hardlywork.ing, my images are getting cropped and losing the top and bottom 25% of the the image, leaving me a zoomed in rectangle. I tried on web browser, phone app, etc. same issue uploading any 1920x1080 photo.

I have no idea what is going on my push notifications on my server are so inconsistent. Sometimes they will make it through and sometimes they won't. Messages seem to work fine however anything to do with calling and video calling notifications just does not want to work.

Sometimes the notification for calls will come through but most of the time it just doesn't want to function.

I have looked in my Docker container logs and there is nothing indicating an error. It all seems to be working, even troubleshooting notifications in the Element client and Element X client. The tests pass with flying colors.

It feels as if my Element clients are not running in the background and completely shutdown. Anytime I re-open the app it looks as if it is opening for the first time.

The only thing I could possibly think is causing the issue is I may not have setup cloudflare tunnels properly. I don't know what would be causing ntfy or matrix to not play nice.

I am running my server on Ubuntu 20.04 with Docker and CasaOS. I am using Cloudflare Tunnels for my Matrix and ntfy containers. The logs for all the containers show nothing abnormal. The issue is appearing on 2 Google Pixel 8 devices that are running GrapheneOS. All the proper settings for the ntfy app and element have been configured (unrestricted battery, notification vibration and sound, etc.) It seems that calls go through fine if the app remains open.

This is what my element app looks like whenever I open it again. Maybe I interpret the loading screen wrong but to me it looks like it's doing "first time startup" type actions. This doesn't make sense though because both client devices are recieving text notifications.

I also found this github issue that seems to be exactly the issue I am facing (except they are having issues with messages as well it seems, when messages is the only notification that works consistently for me). However I don't know if some of the proposed solutions are only applicable to Synapse and not Dendrite.

Thank you all for your time and help!

Edit: some more github issues referencing my issue. These seem more specific as well:

https://github.com/element-hq/element-android/issues/8761

https://github.com/element-hq/element-x-android/issues/3031

I do not know if this value will work in my Dendrite config:

ip_range_whitelist:

I’m pulling my hair out over this. I’ve got a proxmox homelab, an LXC running technitium installed from TTeck’s script.

The DNS server is also doing DHCP for my network. I have an authoritative zone for ‘.lan’

I can get NS, SOA, TXT records from the DNS server, but no A records! The DNS query logs show that it gives an answer, and if I am on the DNS server itself I get an answer, but no other machines on the network hear the reply.

I think this means the DNS server is working properly. There are no FWs in the way as I can resolve other types.

Where else can I look, or how can I diagnose this? I am completely at a loss.

I'm thinking about moving my router to be a VM on a server in my homelab. Anyone have any experience to share about this? Any downsides I haven't thought of?

Backstory: My current pfSense router box can't keep up with my new fibre speeds because PPPOE is single threaded on FreeBSD, so as a test, I installed OpenWRT in a VM on a server I have and using VLANs, got it to act as a router for my network. I was able to validate it can keep up with the fibre speeds, so all good there. While shopping for a new routerboard, I was thinking about minimizing power and heat, and it made me realize that maybe I should just keep the router virtualized permanently. The physical server is already on a big UPS, so I could keep it running in a power outage.

I only have 1 gbps fibre and a single GbE port on the server, but I could buff the LAN ports if needed.

Any downsides to keeping your router as a VM over having dedicated hardware for it?

Not sure if this has already been posted since it's kind of old news (early 2024), but I think that's exciting. I'm currently looking into blog software with nice webgui and I might wait for this to become real. Looking at the announcement page, they seem to take it seriously and there's continuous merged PRs since April until recently regarding AP on their GitHub.

Hi c/selfhosted,

here's another Update on PdfDing, the selfhosted PDF manager, viewer and editor offering a seamless user experience on multiple devices. You can find the repo here.

Thanks to being included in the favorite selfhosted apps launched in 2024 on selfh.st, PdfDings's popularity improved greatly. This week the project crossed the 500 Stars on github, which was a big milestone for me. Thanks! Another thing that made me quite happy is that PdfDing got its first two contributions!

Milestones aside there were also new features and improvements since my last post:

• PDFs can be starred and archived. Starred and archived PDFs can be quickly accessed in the overview. Archived PDFs are hidden from the default overview.
• New (beautiful) theme inspired by fli.so. You can find a screenshot here.
• Preview mode: the first page of each PDF can be shown in the overview without entering the viewer.
• Optional thumbnail mode: The first page of each PDF will be shown as a thumbnail in the overview.
• Design improvements that (in my opinion) make the whole application feel cleaner and more beautiful
• I have created a helm chart so it can be easily installed on Kubernetes

As always I am happy if you star the repo or if someone wants to contribute.

Hey everyone. So I'm trying to decide which RAID should I choose for my 6trays NAS. I have 4 x 16TB HDDs, 1x8TB HDD and another one 500GB ssd that I will use as a containers' docker folder usage. I will be using the NAS to store Media files (movies, tv series, photos, music etc.) and also documents. Currently I have the 2 16tb as RAID 1 that only the Media files are stored and I am in between either creating another RAID 1 with the remaining 2 16Tbs or adding them to the other 2 to create a RAID 5 and have a bigger storage pool Have you had any incident where 2 HDDs were lost-damaged simultaneously (as RAID 5 forgives loss of only 1 drive) or not?

In addition I was thinking of having the 8TB HDD as a standalone to backup the documents and maybe the photos and the docker setups.

Does this make sense to anyone that uses similar setup?

Thanks for your inputs!

For some reason my push Notification are not working properly even with my ntfy server. I will miss calls from people because it doesn't seem like my clients are running in the background on my pixel. I have the battery access set to unrestricted. I do not know why the clients don't run in the background to notify me.

It seems they only really notify me if I keep the client open.

I am using a google pixel 8 running grapheneos. The clients I have tried are: schildichat and element.

I have also tried it on my fiance's google pixel 8 running grapheneos and the same issue appears.

I am running both my ntfy server and matrix server on docker on a ubuntu 20.04 machine with casaos. I use cloudflare tunnels to forward my services.

When troubleshooting notifications it passes all the tests on both element and schildichat. however on element x and schildi next I get an error failed to check gateway and push back loop. (which both element x and schildi next functioning 100% for me yet. See other posts)

Any help is appreciated!

Edit: it seems to be a problem with ntfy. Checking the container logs I found this:

INFO Connection closed with HTTP 500 (ntfy error 50003) (error=internal server error: base-url must be be configured for this feature, error_code=50003, http_method=GET, http_path=/_matrix/push/v1/notify, http_status=500, tag=http, visitor_auth_limiter_limit=0.016666666666666666, visitor_auth_limiter_tokens=30, visitor_id=ip:example, visitor_ip=example, visitor_messages=43, visitor_messages_limit=17280, visitor_messages_remaining=17237, visitor_request_limiter_limit=0.2, visitor_request_limiter_tokens=60, visitor_seen=2025-02-06T09:19:26.984Z)

Edit 2: i seemed to have fixed that error by reinstalling ntfy and creating a config file with the base url. However I am still not recieving push notifications. Element still crashes/closes and stops running in the background. I have no idea how to fix this. I have seen mentions of 'ip_range_whitelist' variables not being set properly. However all the documentation that relates to that variable is only for synapse. I do not know if that same variable is applicable to dendrite. I cannot see it listed in the config file.

I'm routing game traffic on my VPS via wireguard to a home server that has games hosted via docker.

Setup is...

VPS/Wireguard -> Internet -> Wireguard/Dockerized Games Server

Now, my current config WORKS... however I'm curious if there is some unnecessary routing going on.

VPS iptable rules (omitted PostDown)

PostUp = iptables -t nat -A PREROUTING -i eth0 -p tcp --match multiport --dports 61000:61100 -j DNAT --to-destination 10.0.0.3
PostUp = iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE

Game Server (omitted PostDown)

Here are the iptable rules on the game server and the --to-destination part is what I'm curious about...

PostUp = iptables -t nat -A PREROUTING -p tcp --dport 61000:61100 -d 10.0.0.3 -j DNAT --to-destination 192.168.1.14
PostUp = iptables -t nat -A POSTROUTING -j MASQUERADE

10.0.0.3 is the same machine as 192.168.1.14

The reason I'm setting the --to-destination ip to that is because the docker rules that are created in the Chain DOCKER section of the iptable rules are looking for the destination nam-games.localdomain which is my dns entry for the game server. I unfortunately don't think I can change these because I'm using a game server management panel called Pterodactyl that adds these. I also don't want to have to manually add rules to this every time I create a server.

Chain DOCKER (2 references)
target     prot opt source               destination         
RETURN     all  --  anywhere             anywhere
DNAT       tcp  --  anywhere             nam-games.localdomain  tcp dpt:61000 to:172.18.0.2:61000
DNAT       udp  --  anywhere             nam-games.localdomain  udp dpt:61000 to:172.18.0.2:61000
DNAT       tcp  --  anywhere             nam-games.localdomain  tcp dpt:61001 to:172.18.0.3:61001
DNAT       udp  --  anywhere             nam-games.localdomain  udp dpt:61001 to:172.18.0.3:61001

Concerns

The setup I described above is the only config I have gotten to work, but I'm curious if it's hitting the server, then going the router, only to be routed back to the same machine again. If it is, is there a better way to set this up?

I'm in the process of getting my Home Assistant environment up and running, and decided to run a test: it turns out that my gaming PC (custom 5800X3D/7900XTX build) uses more power just sitting idle, than both of my storage freezers combined.

Background: In addition to some other things, I bought two "Eightree" brand Zigbee-compatible plugs to see how they fare. One is monitoring the power usage of both freezers on a power strip (don't worry, it's a heavy duty strip meant for this), and the other is measuring the usage of my entire desktop setup (including monitors and the HA server itself, a Lenovo M710q).

After monitoring these for a couple days, I decided that I will shut off my PC unless I'm actively using it. It's not a server, but it does have WOL capability, so if I absolutely need to get into it remotely, it won't be an issue.

Pretty fascinating stuff, and now my wife is completely on board as well; she wants to put a plug on her iMac to see what it draws, as she uses it to hold her cross-stitch files and other things.

Hi guys! I was wondering whatever solution you guys might use to check/update your servers/containers? I'd like not having to depend on any cloud, something running locally would be great.

Thanks!

A year ago I built a NAS to reduce my reliance on cloud services, and set up an arr stack. I went with TrueNAS Scale, which was on Bluefin at the time. In the past 12 months, TrueNAS Scale has been through FOUR major OS versions, with a fifth already announced. At least one of those involved a release train switch so, despite diligently checking for updates in the dashboard, I was left in the dust with an obsolete OS, and didn’t find out until it was already a huge hassle to upgrade.

I’ve been really happy with the utility and benefit of having this tool, but holy smokes how is anybody supposed to keep up with all of this? This is far from my only hobby, and I simply do not have the time, patience, or interest for a constant race to keep up with vetting new release versions and fixing what breaks every 3 weeks. I have enough tinkering hobbies as it is.

On top of that, there’s the whole blow up with TrueCharts, which has also left me with an entire suite of obsolete albatrosses around my NAS that I need to deal with. Am I still waiting for them to figure out an upgrade path? I don’t even know anymore.

Sorry for the rant, but I guess what I’m looking for is: how do you keep up with the constant maintenance and updates, and where do I go from here, in February 2025, with a system running Bluefin 22.12, a 32TB ZFS pool (RAIDZ1) that has to remain intact, and a handful of TrueCharts apps that I don’t want to lose the data from (e.g. Jellyfin configs/watch history)?

I'm currently shopping around for something a bit faster than ollama and because I could not get it to use a different context and output length, which seems to be a known and long ignored issue. Somehow everything I’ve tried so far did miss one or more critical features, like:

• "Hot" model replacement, so loading and unloading models on demand
• Function calling
• Support of most models
• OpenAI API compatibility (to work well with Open WebUI)

I'd be happy about any recommendations!

• my methods have been:

• use trilium for any detailed notes and documentation

• memos for random thoughts especially if shorter

• pen and paper when offline or on mobile because mobile trilium and moememos both suck

• zotero for citation and bibliography manager

• backed up to nextcloud

• i have paperless-ngx but found it randomly errors a ton of things and zotero is fine.

• considering if it’s worth it to have so many different spread out methods

• theyre fun to use but it creates more chaos then needed

I'm on Arch Linux btw. and I have a RTX 3060 with 12 GB VRAM which is cool so a 14b model fits into the VRAM. It works quite well but I wonder if there is any way to help with the speed even more by trying to utilize the iGPU in my Intel 14600K. It always just sits there not doing anything.

But I don't know if it even makes sense to try. From what I read in some comments on the internet, the bottleneck will be the ram speed in the iGPU, which will use my normal ram which is a magnitude slower than the VRAM.

Does anyone have any experience with that?

Is it feasible to self host websites for small businesses? I'm trying to do some research on the amount of infrastructure and stuff you have to know from a security standpoint... I'm fine with building and hosting stuff locally for me but I'm tempted to move to hosting some of my business sites as well.

Does anyone have experience and can give me some advice one way or the other?

Hello everyone!

After searching and searching for a solution for my issue I think I may have stumbled upon something. I have been trying to get my matrix server up and running so that I can move on to the next project.

The issue I was running into was mobile element Client users could not join group calls. Mobile Element users need to use Element X, however Element X users cannot join my Dendrite server because I do not have sliding sync proxy set up.

I have heard that synapse has sliding sync already enabled but I have not been able to tackle synapse. Dendrite has just worked out of the box for me besides this one issue.

Originally when I was tackling the issue of sliding sync I had read somewhere that it was not compatible with dendrite. So that had crushed my hopes and dreams of using dendrite and I hadn't looked back ever since.... Until now.

I went to the official matrix sliding sync github page and wouldn't you know it, there is a note that says:

NOTE: The proxy works fine with Dendrite and Synapse, but it doesn't work well with Conduit due to spec violations in the state of a room in /sync. Running the proxy with Conduit will cause more expired connections (HTTP 400s) when room state changes, and log lines like WRN Accumulator.filterToNewTimelineEvents: seen the same event ID twice, ignoring.

So now I am trying to set this up with my current matrix dendrite docker image. However I don't really understand how to follow this guide to make it talk to my pre existing containers.

Thank you all for your time!

My system software:

Ubuntu 20.04 with CasaOS and docker

The guide and documentation I followed for setting up matrix dendrite:

https://www.youtube.com/watch?v=TFDFR6EBG3k

https://wiki.opensourceisawesome.com/books/setup-matrix-chat/page/install-matrix-using-the-dendrite-server_

Official sliding sync documentation that I am trying to setup:

https://github.com/matrix-org/sliding-sync

Edit: I was able to get sliding sync to work using the compose file that samsy provided below! I then added the sliding sync container to the dendrite network and now I can sign in with element x and achildichat next with no "this server doesn't support sliding sync" error!

However now these clients do not show my chats, the clients can create rooms however when backing out I still get an empty chat page for some reason.

Edit 2: I have gotten sliding sync working with dendrite! My compose url environment variable was pointing to my sliding sync url and not my matrix server url! Thank you everyone!!

How to easily run a Webdav server in a Docker container

A lot of open source software lets you synchronise data via webdav, but how do you get a #webdav server?
Using Apache with the dav module is a common approach, but I couldn't bother to set it up that way.
My way is different: Rclone can act as a webdav server and is easy to configure.
I've been using it for 3 years and it's very reliable.
Have a look at the compose file in the picture.

I'm trying to get Qbittorrent set up within Docker on my home server and want to configure port forwarding through my VPN for all of those Linux ISOs. Ideally, I also want to get a pipeline going with the *arr stack. I've heard the easiest way to do this is with Gluetun but I can't for the life of me figure it out or know how to test it.

I want to create a NAS for my family at home. I am already pretty sure about using TrueNAS as software, but the hardware is still open.

What hardware do you recommend for 2TB of usable Storage (+a second drive for mirroring the first one) that is used by 3 people for pictures, videos, and documents?
