  • OK, now I am even more interested. dig doesn’t return an A record:

    $ dig glauca.digital a
    
    ; <<>> DiG 9.20.27 <<>> glauca.digital a
    ;; global options: +cmd
    ;; Got answer:

    Somehow, it does work in a browser. I tried different DNS servers as well (including NextDNS which I use in a browser), none returns an A record (or AAAA). So, naturally, I am curios what IP the browser uses. Since it clearly works, I tried ping just so that I could see the resulting IP, and figure out where it’s coming from.

    $ ping glauca.digital
    ping: glauca.digital: No address associated with hostname
    

    Great. That makes absolutely no sense at all. Where is Firefox getting the information from?
    So I went to about:networking DNS tab. The address field is empty. I am just typing this as I test. It’s just cache in my browser.

    I guess that would answer on reliability question. At least their nameservers still resolve to IP.








  • Problem with plain Wireguard is if you can’t open ports on some devices to get a direct connection. It should be just fine with hub and spoke model, but NAT Traversal of Tailscale makes a huge difference. I can get a direct connection between 2 devices connected to mobile data and behind CG-NAT.
    And also the config management if you have too many devices.

    Hub and spoke, you just add new devices to Wireguard on the main device, and the new peer. Full mesh, oof.

    But as far as configuring Wireguard goes, that’s pretty simple. And then there’s the weird stuff with MTU and fragmentation… but that’s not something Wireguard-specific.













  • If it is a hardware failure, I don’t see why it should be an issue. I know re-installing Windows is something PC repair shops do often, and I don’t see how that’s different from any other OS.

    fault or failure resulting from software

    Unfortunately, that’s quite broad. But it could also just apply for stuff like overclocking or firmware modifications. Or even simpler stuff. I could see someone having DVDs from multiple regions, changing drive region every time until they hit the 5 changes limit, and then trying to claim it for warranty (I’ve had some software on Windows do that automatically…).

    Should I submit it with the Linux installation intact or replace it a fresh install of Windows

    Or if there’s private data, overwrite it with output of /dev/urandom or /dev/zero. blkdiscard might also be your friend since it’s an SSD.

    I am doubtful whether they have experience working on anything other than Windows

    Probably they’ll just test the rest with their own drive or re-install it.

    Or maybe try to ask them how to prepare the device for the warranty claim.
