I mean if you have an angle grinder and a space to safely use it sure. But it’s still harder than just dropping the HDD off at an e-waste bin.

Fair. If you have access to a crusher then maybe I can see not encrypting. But even then with non encrypted drives files can be recovered even after deleting etc.

This is why backups are important. But even if the drive is encrypted recovering data is exactly as easy as recovery from a non encrypted drive.

1. Do a ddrescue of the drive.
2. Re apply the luks header.
3. decrypt all non corrupt sectors
4. Use appropriate tools to recover files.

Like you lose the same sectors if those sectors are encrypted or not.

I mean Americans do a lot of dumb stuff. And I don’t think we need to make every thread American centric.

True if all of your knowledge of religion comes from pop culture I can see how someone might see it that way.

Like in Family Guy or other Seth Rogan shows Satan, Jesus and “God” are all depicted as equals bickering.

Thanks for your thoughts here. They’re interesting.

I’m guessing you don’t come from a region that has been historically Abrahamic. I’m secular myself but it’s interesting that you would throw Satan in there with the rest.

Just backup the LUKs header files. No need to encrypt them as they’re inherently secure as the hard drives they would originally reside on.

True. This does work. But it is less secure and much harder than just tossing an encrypted HDD into an e-waste bin. It probably is more fun though. 🤔

I would strongly encourage people to encrypt their on site data storage drives even if they never leave the house and theft isn’t a realistic thing that can happen.

The issue is hard drive malfunction. If a drive has sensitive data on it and malfunctions. It becomes very hard to destroy that data.

If that malfunctioning hard drive was encrypted you can simply toss it into an e-waste bin worry free. If that malfunctioning drive was not encrypted you need to break out some heavy tools tool ensure that data is destroyed.

That is a good reason to backup, but has nothing to do with encryption.

(For real though I have a backup of all of my drive LUKS headers stored on several media types on and off site.)

Yah that term isn’t an official term. I just meant it in the sense of a IPv6 prefix. Without knowing more about how your router firewall works / in set up I can’t be too specific.

But in general the way things work with ip addresses is that your ISP provides you with a block of IPv6 address. This block is the prefix/first part of any given ipv6 address on your network. Each host uses that prefix and generates a suffix that it adds in to it in order to generate a full globally reputable IPv6 address.

By default most hosts use the IPv6 privacy extension to random suffixes and cycle through them. This is good for privacy but bad for hosting a public service. You need to turn off the privacy extension and the second half of the IPv6 address will stay static.

Next up you need to write a firewall rule to allow traffic to that globally routable IPv6 address. In an IPv6 system the router does not intercept or rewrite the packets like it does with IPv4. So all a router does is act as a firewall saying “Yup outside hosts can or can’t make inbound connections to certain hosts/ports”

The trick with a consumer IPv6 address space is that just like IPv4 addresses given to your router, the IPv6 prefix can change randomly.

It would be annoying to have to update the firewall rule every time this happened. That’s why the idea of masking matters. You tell the firewall “ignore the prefix of this firewall rule. Just allow or deny based on the static suffix.”

The way to write such rules is different on different firewalls. Most consumer devices don’t have a way to configure such things. Even professional networking equipment mostly makes you use the cli to manage such things.

I hope this helps.

I’m glad you got it working with IPv4. For the record though the way to do such a thing in the future is to think in IPv6. In IPv6 there is no nat or port forwarding. Even if you have host exposure. You need to set an appropriate rule in your router firewall.

On the host itself you need to use public IPv6 addresses. Then on the router firewall you set a firewall rule with an appropriate delegation mask allowing traffic to the specified port.

It’s different than IPv4 but once you learn IPv6 it’s easy.
