I keep hearing claims that it’s not secure enough to be exposed on the Internet, but I can’t seem to find anything about unauthenticated vulnerabilities. It’s got a fair amount of CVEs but they all seem to affect when you’re an already authenticated user, mainly to XSS an admin as a regular user or the likes.

It’s written in C#, and publicly all you can do is pretty much attempt to log in, this feels like it should be pretty sane compared to some other PHP crap I run.

Do you have any examples of previous exploits or anything else to be concerned about?

It’s literally been working just fine for like a decade? Even for NVIDIA users that’s kind of a stretch.

Maybe if you share more details about your issues and your setup we can help fix it.

NixOS isn’t a bad option, I’m not sure how much you can trim it down but I’d expect it to be possible to express in Nix to install to a target that’s different from the host. Maybe not NixOS but Nix itself as a package/config manager. I’m sure at minimum it makes for a great development environment for building a buildroot.

It’s hard to give concrete advice without knowing the specs or the software you want to run on this, but for tiny Linux systems there’s Buildroot so you can compile just the bare minimum you need and not use a distro at all (unless you could Buildroot as a distro). This is what OpenWRT uses to build all the router firmwares among other things.

For something that would go in a car that seems pretty ideal to me. Skip initializing things you won’t use, make something that boots to GUI in 3 seconds. When you want to update the software you flash it as a new firmware image, no on-device installing or anything.

Depending on what you run, ideally you’d skip Xorg/Wayland and use the framebuffer directly. But if you need to run a more standard environment, that’s what things like Cage are designed for. Single app, always full screen. It’s called a kiosk environment.

Is it directly exposed over the Internet? If you only port forward the VPN on your router, I wouldn’t worry about it unless you’re worried about someone else already on your LAN.

And even then, it’s really more like an extra layer of security against accidentally running something exposed publicly that you didn’t intend to, or maybe you want some services to only be accessible via a particular private interface. You don’t need a firewall if you have nothing to filter in the first place.

A machine without a firewall that doesn’t have any open port behave practically the same from a security standpoint: nothing’s gonna happen. The only difference is the port showing as closed vs filtered in nmap, and the server refusing to send any response not even a rejection, but that’s it.

Proton is Wine but tweaked for the sole purpose of running games, so it packs a bunch of extra stuff needed to make games run well together.

Usually there’s also a long list of per-game tweaks and changes to make sure it runs, it’s all preconfigured so you press play in your launcher and it works. Not need to change settings whenever you want to play a game.

You can still use regular Wine but you’ll have to set up a bunch of stuff yourself, and eventually you run into a game that needs a different version of something that breaks another game, you get into prefix management and it’s a mess. Or oh this game runs better when we pretend to be Windows 7 but this one works best with Windows 10. Proton just does it all for you, every game gets its own space with all the correct settings from the get go, and you just launch into the game and play.

Honestly a VPN that doesn’t support Linux at least through manual connection settings, run away. All reputable and even the sketchier VPN providers support Linux, because that’s what the privacy crowd uses, not supporting it implies those aren’t even the target user base at all. It’s a red flag. It’s not a VPN for privacy or getting another country’s Netflix.

I’d trust Norton about as much as my ISP, so unless you use public WiFi somewhat often, it doesn’t add much value, just the downsides of captchas everywhere. They’re probably analyzing the traffic to map out malware campaigns and such, which would make sense but isn’t very private.

The business model of antivirus companies is fear, and they sell the solution to that fear. They have a VPN because people assume VPN means more security, of course they’ll sell you one. At best they block known malware domains and IPs, which is utterly useless on Linux anyway.

If you want a VPN get a real VPN.

Proof of work is what those modern captchas tend to do I believe. Not useful to stop creating accounts and such, but very effective to stop crawlers.

Have the same problem at work, and Cloudflare does jack shit about it. Half that traffic uses user agents that have no chance to even support TLS1.3, I see some IE5, IE6, Opera with their old Presto engine, I’ve even seen Netscape. Complete and utter bullshit. At this point if you’re not on an allow list of known common user agents or logged in, you get a PoW captcha.

Back in the days we’d get free hosting and slap phpBB on it. Run for kids by kids, no pesky adult rules!

Those were the days. No credit cards needed, no nothing, just free 50MB of Apache/MySQL/PHP4 hosting with no strings attached.

If the fediverse was a thing I’d probably have had my own instance starting age 14-15ish.

I was totally above 13 or had parental consent when I went to forums in the early 2000s. I totally wasn’t actually 9.

It’s wild to me this concept disappeared? It’s literally never been a good idea to reveal you’re a minor online. The laws are against you. Companies don’t want to deal with a curated minor experience, even less so in the current times. If they do, you get the crappier version of things.

The worst thing to happen to the Internet is when Facebook normalized using your real name and real info online.

It’s still not ideal but you can at least set a charge limit and set it really low like 50% which is about where those batteries degrade the least.

But yeah using a lithium ion battery as a capacitor ain’t great. BMS is just gonna charge it some, let it drain, charge it some, let it drain, repeat over and over again. There’s a reason store phones tend to become spicy pillows so much after a while of being on display always on always running some animation.

This is already what happens when you leave it plugged in to charge overnight, except it uses very little power so the battery only gets topped off a handful of times.

The heat caused by the busy CPU would also be a rather big problem for the battery.

It’s not impossible, been running my own email server for about 10 years and I inbox pretty much everywhere. I even emailed my work address and straight to inbox. I do have the full SPF, DKIM and DMARC stuff set up, for which I get notices from several email provides of failed spoof attempts.

Takes a while and effort to gain that reputation, but it’s doable. And OVH’s IPs don’t exactly have a great reputation either. Once you’re delisted from most spam databases / old spam reputation is expired, it’s not that bad.

Although I do agree it’s possibly one of the hardest services to self host. The software to run email servers is ancient and weird, and takes a lot to set up right. If you get it wrong you relay spam and start over, it’s rough.

I feel like a lot of the answers in this thread are throwing a lot of things with a lot of moving parts: Unraid, Docker, YunoHost, all that stuff. Those all still require generally knowing what the hell a Docker container is, how to use them and such.

I wouldn’t worry about any of that and start much simpler than that: just grab any old computer you want to be your home server or rent a VPS and start messing with it. Just pick something you think would be cool to run at home. Anything you run on your personal computer you wish was up 24/7? Start with that.

Ultimately there’s no right or wrong way to do things. It’s all about that learning experience and building up that experience over time. You get good by trying out things, failing and learning. Don’t want to learn Linux? Put Windows on it. You’ll get a lot of flack for it maybe, but at the very least over time you’ll probably learn why people don’t use Windows for server stuff generally. Or maybe you’ll like it, that happens too.

Just pick a project and see it to completion. Although if you start with NextCloud and expose it publicly, maybe wait to be more comfortable with the security aspect before you start putting copies of your taxes and personal documents on it just in case.

What would you like to self host to get started?

You’ll first want to lock down the laptop with using the TPM so it only boots kernels signed by you, and also encrypt the drive using the TPM as the locking key so the key is only ever available to a kernel you signed. From there you’ll probably want to use dm-verity to also verify the integrity of the system or at least during the boot process.

Then, on top of that, once online and the machine is still authorized to access that data, you download a key from a server under your control to unlock the rest of the drive (as another partition). And log those accesses of course.

Then, when you want to revoke access to it, all you have to do is stop replying with the key whenever requested. That just puts a ton of hurdles to overcome to access the data once the server stops handing the key. They would have to pry out the key from the TPM to unlock the first stage and even be able to see how it works and how to potentially obtain the key. They could still manage to copy the data out while the system is fully unlocked and still trusted, which you can make a lot harder by preventing access to external drives or network shares. But they have physical access so they kind of have the last word if they really really really want to exfiltrate data.

This is the best you can do because it’s a passive: you stop supplying the unlock key so it’s stuck locked encrypted with no key, so the best they can do is format the laptop and sell it or use it for themselves. Any sort of active command system can be pretty easy to counter: just don’t get it online if you suspect the kill signal is coming, and it will never come, and therefore never get wiped. You want that system to be wiped by default unless your server decides it’s not.

You just put both in the server_name line and you’re good to go.

Yep, and I’d guess there’s probably a huge component of “it must be as easy as possible” because the primary target is selfhosters that don’t really even want to learn how to set up Docker containers properly.

The AIO Docker image is an abomination. The other ones are slightly more sane but they still fundamentally mix code and data in the same folder so it’s not trivial to just replace the app.

In Docker, the auto updater should be completely neutered, it’s the wrong way to update the app.

The packages in the Arch repo are legit saner than the Docker version.
