I’m guessing they can rip the other end of the lock out of the wall tbh.

But realistically, theifs aren’t that sophisticated, they aren’t going to waste time trying to find and destroy the DVR, the will grab whatever valuables they can carry and pawn and leave as fast as possible.

The cameras are really just a deterant, they will move on to an easier house instead of risking it with mine.

Home security first of all, with cameras to deter thiefs. That alone mostly solves the problem, but I’m in a relatively safe area.

My “lab” is just a switch, nuc and unifi cloud key, and while they are warm in their closet, its not super hot.

I have a Kensington lock on the security camera box, but someone could theoretically yank that out of the wall.

The rest really isnt worth breaking in to steal.

When I used to have SSH on a nonstandard port, I got login failures from bots. It really depends on the bot and how aggressive they have set it up.

I dunno where you are getting your discussion from, but those points have come up very frequently.

iPhones have locked bootloaders, and that likely will never change.

So would not Faraday caging my house, guess which is cheaper :D

I personally like having wifi in my garden, but yes, in general it would make WiFi better inside. And painting internal walls would be silly.

Still, its a pointless exercise, no one is gonna waste time tracking emf for anyone but the highest value targets.

That shit is unimaginably classified

Check warthunder forums :D

EMF paint definitely exists, its been used on military planes for decades now. But the emf paint from Aliexpress? Definitely sus.

EMF observation may be technically capable of all of those things, but realistically, anyone who would go to that extreme (of targetting a single households occupants) is equally capable/likely to just barge in, arrest you and slap an ankle monitor and security cameras in your house. So its kinda pointless to worry about it.

This is well into literal tin foil hattery, but:

You’d have to check what kind of frequency range it actually protects against, and you’d need a way to test it (no doubt there is some fake emf paint around as well).

You could also wrap your walls in chicken wire and get a pretty decent Faraday cage effect for cheapish.

It’ll also break your wifi and phone (if it works).

Unless you are running a spy agency, this is just a waste of effort IMO.

11-12 should be well tested. 12-13 should be well tested. 11-13 may work, but you may be the tester.

I’d step through one at a time.

Bummer. You could get a cheap IoT light bulb/smart plug and ping it in a script, when it times out, start the shutdown. Could be a fun project.

Some (most?) UPSs have a way for them to communicate to the PC so that the PC can automatically cleanly shutdown. You should look into that if its available on your UPS.

Yeah, it prevents booting on that motherboard, but they can just yank your disks and boot it on another motherboard.

Normally, a good bios password implementation shouldn’t reset with CMOS battery, but for yours it seems it does.

Bios passwords dont provide security at all. At most, mild theft prevention (that is trivially bypassed). If you want security, disk encryption is what you want.

Replace your CMOS battery, NTP is good to, but you really don’t want your CMOS freaking out.

Whats your goal? Your current network works presumably, what are you trying to achieve by upgrading? Faster network? Reliability? Expansion options?

Probably best to get a count of both, and I’ll check back in a week. :)

They are very intense tools, certainly gives me the sweats when I have to use mine. Use clamps where possible.

How many fingers do you have? :)

Ctrl-alt-Fnumber until you get to a tty shell. Login, run journalctl - f. Ctrl-alt-Fnumber until you get back to login screen, and login. Go back to tty and see what errors got logged.

If you have ssh enabled you can also ssh in and run the journalctl cmd. You’ll have to try different F number keys, I dont remember which ones get you a tty and which gets you the login. Start at F1 and move across, but wait a bit, sometimes it can take a while to spawn the TTY.

Conceptually, not a problem. Windows 11 runs on top of HyperV with no performance issues. In reality, I think you will spend a lot of time, hit lots of weird edge cases and performance issues, especially with trying to get the Linux and windows hosts to coexist nicely.

That said, I’d love to watch you try :)
