[LockBox-LBX] Created a Hardened Linux OS for Crypto Hodlers

[MagnumOpus3k]

No worries Dave, I think security should always include a solid dialogue and its a valid point. I'm currently reviewing Technitium DNS Server and will need to perform a bit more research before implementing. I think this may fall along the lines of your request?

Looks promising, will have to look into it too.
It's amazing how much information you leak using public / your internet providers DNS.
And how many people & places still refuse to use DNS over TLS.

Look a hardware wallet connected to an encrypted PC connected to an actual cable to the SonicWall router.
And lets go to Coinbase using local ISPs DNS lookup. And now we know you have (or are interested in) crypto.
And since your local ISP probably is not using DNSSEC, who knows if you are really at Coinbase anyway.
Yes, and extreme edge case, but still worth thinking about.

You're right.

Hey Dave,

Just a quick follow up.  resolvconf has been installed and the nameservers below have been set to permanent (default):

nameserver: 9.9.9.9 (Quad 9) - Main - DNS over HTTPS (aka DoH)
Link:https://quad9.net/news/blog/doh-with-quad9-dns-servers/
nameserver  1.1.1.1 (Cloudflare) - Fallback - DNS over HTTPS (aka DoH)
Link: https://developers.cloudflare.com/1.1.1.1/encrypted-dns
nameserver: 127.0.0.53 (Local) - Fallback

Technitium looked great, however after a hearty conversation with the team no one liked the idea of this remotely resembling a DNS server

[MagnumOpus3k]

nameserver  1.1.1.1 (Cloudflare) - Fallback - DNS over HTTPS (aka DoH)
Link: https://developers.cloudflare.com/1.1.1.1/encrypted-dns

You're joking right? I understand Cloudflare is reliable service, but it's bad for privacy and people report few website can't be accessed when using CloudFlare DNS. I would suggest looking for alternative DNS such as NextDNS which is used by Firefox.

Hey ETF,


I believe this is indirectly part of that rabbit hole Dave was referenced earlier.     NextDNS is great, however they typically do have more performance issues than their competitors. From a reliability perspective this gets tricky. Some users may also perceive latency or blocklist issues to be issues related to the LBX image itself, hence the call for Cloudflare. This now becomes a question of finding a happy medium or reverting DNS configurations back to default for user configuration. From a privacy perspective, the assumption should be held that all providers retain logs even when they say they don't. I think NextDNS is headed in the right direction however the best course of action is the use of a solid VPN service. Thanks again for taking a sec to highlight this.

Perhaps an option at install? Let the user pick what they want.

1) Use DHCP assigned.
2) Use 1.1.1.1, 8.8.8.8, 9.9.9.9 etc. While letting people know that they are probably going to be logged
3) Use NextDNS / others but let people know about possible performance issues / blocking
4) User configured DNS servers.
5) Install BIND and let them know about the bloat that comes with it.

Look, Dave just dumped a couple of weeks of programming and testing on someone :-)

Thanks Dave For the sake of finalizing the image, I've reverted back the configuration and commented out DNS services Quad9, Cloudflare and NextDNS. User may configure to their discretion.

[MagnumOpus3k]

I get the point, but i would rather choose DNS that might keep log you (but the privacy policy/their website still respect your privacy) than DNS that obviously keep log.

For sure, until we can come up with an method of simplifying this on a user-friendly basis, I've reverted back theses changes to default. I think this is an area of which it would be hard to satisfy the needs and the wants of specific users.  

[MagnumOpus3k]

Original post has been updated to include snapshots and a list of software/application installed on the latest image. I'll be working to tidy up a few more items over the weekend including, distrowatch, website and git. Thanks again for the awesome feedback and I look forward to improving this project with community feedback as we progress.

Even if you want your bundle becomes more secure (crypto tasks only), it is better to remove graphical desktop.

Their user demography are new linux user and people who want simplicity. Besides, i wonder how many linux user who remember command for connect to internet over WiFi.

Furthermore, simplicity is also an issue for some not familiar with Linux, so packages like eddy are installed by default to help install applications.

It's not just Wi-Fi it 100s of things. I might be able to run a complete linux server from an SSH terminal window from what I know, every time I have to do something with bitcoin from the same window I am looking up what to do since I do 99% of BTC through a GUI. And don't even ask me to try to run something like electrum from a terminal. It would be a google fest to find the answers.

Nearing completion of the latest image and should have this it available shortly. Please see the list of installed applications below:
Git: https://github.com/StratousLabs/LockBox

Do you have any updates regarding listing LockBox on DistroWatch, because I don't see it listed yet?
If you didn't do it so far you can contact them directly and follow instructions on distribution submission page.
Interesting thing about DistroWatch website is accepting of Bitcoin and Monero donations, along with regular paypal donations.

Hey dkbit,

Just a follow up, we've been officially listed on distrowatch and paid in BTC of course  Thanks again for the suggestion!

https://distrowatch.com/table.php?distribution=lockbox

[MagnumOpus3k]

Quick Update - A signed ISO was requested yesterday and is now available via the site. Key and sig are both publicly available via our git.

Nice work, bit I didn't know you have to pay to be listed on that website... if it's not a secret can you tell us how much they charge for this?

I see that ISO size is around 3.4 GB but I am wondering what are the minimum system requirements (RAM/CPU) needed for running LockBox Linux, and is it possible to run it on some old laptop computer?

Thanks and sure thing.  To be promptly listed and to buy a tiny bit of advertising space was roughly $220. Thought this to be extremely worth it as it also  serve as direct support for distrowatch.  Also here are the  critical specs:


Dual Core 64-bit processor / Intel i3 or Intel i5

8 GB of system memory (RAM)

​120 GB SSD


Running on a older laptop with equivalent specs shouldn't be an issue, however the experience may be a bit painful. Running opensnitch and a full node wallet can quickly chew up resources.

I don't know if there is any better and free alternative website for distrowatch, many people think they are a bit bias with their rankings, meaning if you pay more you get higher on their list and many wonder if MX linux got on topo like that.
Good thing about distrowatch is that they are accepting Bitcoin donation.

Oh there is no way I could run that on my ancient laptop that has only 1 GB system memory

Yeah I thought the process over at distrowatch was great as they did actually perform checks of the LBX image beforehand. We did see a notable bump in traffic after our purchasing ad space for a week for sure. However the true goal of course was to increase exposure and trust. And it was a huge plus they accepted BTC.



 As for your laptop,  Certainly would be frozen on arrival.

Is it minimum or recommend specification? For a second i though i read specification for modern video game. What makes this distro have high specification requirement (for example Qubes OS have high requirement because hypervisor usage to perform isolation)?

  Certainly recommended. 4GB of RAM is certainly doable but becomes sluggish once the user gets everything they prefer loaded.  Bitcoin Core will utilize roughly 1GB/RAM &  OpenSnitch up to 2GB/RAM. Matched with Chromium based browsers and other full node wallets like Daedalus, it quickly becomes a circus.  I found 8GB best for overall user experience though not necessary.  With regard to the processor, i5 certainly provides a smoother experience.

You definitely need to mention it's recommended specification on your page, many people will assume it's minimum if you only list 1 specification. Adding note why 8GB RAM/i5 is recommended also helpful since i doubt user run all of the application you mentioned at once.

Great advice ETF. I'll updated this immediately and expand further in the future. Thanks again.
