From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

I'm not a security specialist either. I learn new things every day, but this is why my NextCloud is accessible through TailScale only and I have zero ports exposed to the outside world.
The only real convenience I lose is being able to say "check out this thing on my personal server" with a link to someone outside my network, but that's easily worked around.
Next: how do we know tailscale's network hasn't been backdoored?
Headscale. And then you don't even have to trust any outside auth provider to not log in in your name.
I figure there's a certain amount of trust you have to have in strangers for a LOT of things we use every day.
I try to be selective with where I put that trust, especially when I can't just homebrew an advanced custom solution, but I figure Tailscale is much better than attempting to just host it on my LAN with an open a port to the big scary web and hope a bot doesn't find a gap and ransomware it all lol.
3-2-1 backups and a certain bit of trust.
Because heck, even CPUs have been found with exploitable microcode. (Spectre and Meltdown?) At some point you just gotta balance "best rational protection" with not going insane, right?
Headscale mentioned here is pretty neat too, but I feel like spinning up Dockers on Proxmox and Tailscale is as much moving parts as I'm willing to manage alongside everything else in life. :)
I think you can use Tailscale Funnels for that.
