I recently set up something similar to this. I can’t comment on your specific hardware, but I was very frustrated with the limitations of TrueNAS and ended up using Debian and Cockpit with BTRFS for the drives.

I started with two 18TB drives with no RAID, and have since added two 26TB drives with everything’s using RAID1 and ~45TB of usable storage. Converting and adding drives was very simple, but also time consuming of course.

Happy to help!

You can find a bit more information at the URL below, and feel free to message me if you run into any issues getting it set up.

Cheers to your journey so far, and to your continued success!

You can absolutely do free SSL certs with Let’s Encrypt without exposing your infrastructure to the internet. Just use DNS based validation instead of HTTP, copy the required TXT records to your domain as instructed, wait for any cache/TTL of any old records to expire (generally 1-2 hours by default), and finally complete the validation.

You’ll need to renew the certs every 3 months, which could be annoying if done manually. If your Registrar has a decent API, writing a script could be a fun automation project. Alternatively I can also send you scripts that I used to use for that purpose.

As a sanity check, I just completed the same setup that you described (Ubuntu Server 24.04 running in a Proxmox VM, Domain name pointing to a CNAME that points to the Dynamic IP, using the installer script, enabled CrowdSec, etc.), and everything worked out of the box. A couple of things I noticed that would also be worth checking now that I’m more familiar with this specific setup are:

• In the config/config.yml file, verify that the dashboard_url is set to the FQDN of the full URL (e.g. pangolin.mydomain.com), and that the base_domain is set to the root/apex domain (e.g. mydomain.com).
• Double check those DNS records. As the haiku goes: it’s not DNS, it couldn’t be DNS, it was DNS. dig pangolin.mydomain.com or dig @1.1.1.1 pangolin.mydomain.com should show the CNAME that points to the A record.
• A 404 page not found error is normal when connecting to the IP address directly rather than using the domain name. I was successfully able to access the dashboard using the FQDN from a local and external network. Depending on your network, you might want to set up a local DNS record that points to the internal IP address as well (though this should be optional in most cases to my knowledge).

I hope that helps!

The script should take care of that config, but it’s something to check just in case there was a typo or anything else like that.

Did you check to make sure the DNS records are resolving properly?

According to the docs, you should be using UDP port 51820 (unless you changed the port in the docker compose file).

You should also check the dynamic config file to be sure that it’s using the correct domain name. See this page: https://docs.fossorial.io/Getting%20Started/Manual%20Install%20Guides/docker-compose

If you’re still having issues, make sure the containers are running with docker compose stats and check the logs with docker compose logs -f. It might also be worth checking the domain name to be sure that it’s resolving to the correct IP address, both locally and externally.

No worries! Yes I’m absolutely still interested, and I have the optiplex set aside for you.

I currently run it with Keycloak for Auth and previously had it behind a Nginx Proxy Manager reverse proxy, but have since switched to using a Cloudflare tunnel.

It works great and allows me to provision limited and controlled access over various game servers to admins of those servers. They can access what they need and nothing more, and only on the servers that they have been granted access.

I use Apache Guacamole, which works great for just about any kind of remote access and has a dead simple to use Docker Container.

It supports folders, copy/paste, uploading/downloading files, multiple open connections at once, and alternative mouse modes for touch screens. Best of all, it’s completely free and open source.

Imagine if OP asked: “I want to repair/maintain my own car, but I don’t want to open the hood or get under the car. What are my options?”

Obviously there would be some options, but those options would be very limited and not ideal. This is very similar. Self-hosting, like self-repair of a vehicle, requires some foundational knowledge and understanding of your specific hardware, usecase, and needs, as well as the knowledge and ability to bring those things to fruition. There is no single universal answer that applies to everyone, but those skills can be acquired by anyone.

I don’t think self-hosting is any more doomed than self-repair of a vehicle. It’s certainly not for everyone, but it can be satisfying, rewarding, enjoyable, and generally optimized for those who choose to participate.

Interesting and good to know, thank you for the info! I haven’t run into that issue with synapse yet, but I’m also running it in a docker container on an enterprise server. I also don’t currently have any chat rooms with more than 5 or so users, and I imagine that is also a factor.

How does this differ from something like synapse?

I also don’t use Mint personally, but based on their releases page, it looks like they follow the Ubuntu LTS releases. The latest LTS version of Ubuntu is already being used for Mint 22.1, so I wouldn’t expect to see Gimp 3 until the next LTS release in April of 2026.

Debian based distros are notorious for using old, but known stable packages. That’s kind of their whole thing. If you want the latest and greatest, look for a rolling release based distro.

Sorry for the late reply. The optiplex is absolutely sold as a desktop, but I’ve been using it as a server for a couple of years. Very small, quiet, and it sips power, but it only has support for 2 2.5" SATA drives (though it does have plenty of USB 3 ports if you don’t mind using external storage). TrueNAS installed on it would be similar to your Synology setup (without the vendor lock in), though not nearly as convenient as the front bays you’re used to.

It’s yours if you want it, but no worries otherwise.

That would be awesome. I have a Dell Optiplex 7040 Micro that might be better suited for your needs after you play around with the big server. Maybe we could trade?

Depending on where you’re located I would happily pay for shipping.

If you don’t want it, I’ll take it off your hands. I have a rack designed for that kind of hardware and all of the infrastructure to fully support it.

I would recommend editing your fstab and use the USB drive’s UUID to mount it to a consistent location. That way, even if you reboot or disconnect the drive and the reconnect it to, say, a different USB port, it will always mount to the same mountpoint.

See this page from the arch wiki for more info.

is there a Linux… idk what to call it, type? OS? Thing??? that runs out of the box without me having to install additional software manually or at least automatic setup wizards

The word you are looking for is called a distribution, or distro for short.

I’m surprised no one else has mentioned Bazzite, which should be exactly what you’re looking for.

is there any specific hardware that works easier with Linux

An AMD GPU for sure. Nvidia drivers have come a long way, but they don’t generally behave as well out of the box like AMD.
