Hairpin NAT/NAT Reflection can make the experience of visiting the WAN IP from the LAN a different one then if you do it from somewhere else. Or what is your what?

As long as you make yourself some aliases for your common ffmpeg commands including flags I’m sure it’s gonna work out fine. Using something like OBS is gonna make it a lot easier of course.

First off, check that it is also true when using a device outside the LAN. Easiest would be to check with your phone with wifi off. You probably won’t get to the login.
If you do then it’s time to check firewall settings.

A DIY solution like your home server is great. I’m just adverse to recommending it to someone who need to ask such an open ended question here. A premade NAS is a lot more plug n play.

Personally I went with an ITX build where I run everything in a Debian KVM/qemu host, including my fedora workstation as a vm with vfio passthrough of a usb controller and the dgpu. It was a lot of fun setting it up, but nothing I’d recommend for someone needing advice for their first homelab.

I agree with your assessment of old servers, way too power hungry for what you get.

A simple way to ensure your selfhosting is easy to manage is to get a NAS for storage and then other device(s) for compute. For your current plans I think you’d get far with a Synology DS224+ (or DS423+ if you want more disk slots).
Then when the NAS starts to be not enough you can add an extra device for compute (a mini pc or whatever you want) and let that device use the NAS as a storage.
Oh and budget to buy at least one large USB Drive to use as a backup, even if your NAS runs a redundant RAID.

I also tend to fall back to Clonezilla. I don’t feel that the Rescuezilla GUI adds much.
Regarding compatibility both the latest Rescuezilla (since September 2024) and Clonezilla (Since July 2024) uses partclone 0.3.32 so they should once again be compatible.

I don’t think you’ll find much use for more than 1 Gbit/s internet but if your desktop pc has a free pcie slot you can look at buying a 10Gbit/s pcie card and a 10Gbit/s network switch as your backbone for fun. You’ll rarely have use for it though.

I imagine you’re talking about bandwidth and that your 300MB is actually 300Mbit/s and all your Gs are Gbit/s.
The fastest ADSL I’ve heard of is 24Mbit/s downstream, aka ADSL2+/G.992.5. You don’t have ADSL.
I would guess that your “ADSL” is actually fiber and that your “Cable” is coaxial cable (same type that gives you cable tv).
If you wanna use more than 1Gbit/s your devices also need to support it. Even with WiFi 6 you will seldom reach 1Gbit/s so we’re talking CAT6 cables and a motherboard that supports at least 2.5Gbit/s.

There are some unofficial Nagios Docker setups, such as https://github.com/JasonRivers/Docker-Nagios
Here’s their configuration doc: https://assets.nagios.com/downloads/nagioscore/docs/nagioscore/4/en/configmain.html
It isn’t all that pretty, see some examples at https://sourceforge.net/projects/nagios/ , but it allows for email alerts, multiple hosts (including managed network devices) and monitoring CPU / Memory / Disk space.

I’ve only ever run it as a full VM so I can’t give much thought on the docker container.

Just wanna shout out that Intel are supposed to have fixed their troubles with 13th and 14th gen cpus, I know Dell went out with a customer advisory in October to update the BIOS to fix said trouble.
https://www.theverge.com/2024/10/4/24262287/intel-13th-14th-gen-crash-raptor-lake-root-cause-fix

And Intel CPUs are great when it comes to transcoding just like the AMD X3D CPUs are king when it comes to gaming.

If you got another psu then that would probably be the simplest way to verify if its the psu or not.

Seems so, yes.

I’d look at wireguard / tailscale / headscale and hide your services behind a vpn

They say nothing about their distro having no upstream. If they make a distro based of Debian/Arch/Fedora I don’t see that as dismissing their efforts anymore than Nobara/SteamOS/Ubuntu/Mint does.

I rather they enforce their requirements on their own spin then try to force existing distros to implement said reqs. They should obviously donate to the foss community when using the technology the community maintain though!

EU is behind the restrictions for vaping liquids, not Sweden. :)

Yeah, they had started limiting what you could buy in Sweden as well. My last time mixing I bought a silly amount of 18mg/ml 10ml strong menthol bottles and large 70/30 PG/VG bottles and ended up with my own 3mg/ml mixture that still tasted menthol, although not as overwhelmingly so.

I think part of it is something else - ease of use and ease of access.
The “world that makes sense” product exists already:

While I was vaping I mixed my own liquids though, as the cost savings was immense and I could easily lower the nicotine mg/ml on my own until I quit it altogether.

Yeah, if there’s a full system failure without any backups and no option to get the system operational again then I would land in clone the drives before trying to restore data from them.
