    At this point, I’ve found a carrier that does 10GB for $17 a SIM (and I could probably get away with less data for cheaper), and I’d be fine with that. I have several rPis that act as hubs taking in LoRa data from things like solar pumps, water bowls and bins, but backhauling to the central server over LoRa is a pain, and we don’t have LoS to all of them so using radio bridges is spotty. Some sites are 10km away over hills. And moving everything to MQTT would make my life easier than my custom BS programming that has devices talking to each other directly.

    We don’t generally have issues with phones and where I do, I can probably put up an antenna if the dongle has an external port, or I’m willing to spend extra $$ for an uplink with external. I currently have a Microhard LTE-CAT4 that I use on one remote site that seems to get good reception, but that unit is pretty pricy and I have to fart around with network cables and power when I could just be plugging in a USB dongle.

    I see a lot of cheap ones on Amazon, but I was hoping someone had a common Linux specific model they know works, because most of those look pretty janky.










  • Governments are not anyone’s issue other than other governments. If your threat model is state actors, you’re SOL either way.

    Making it harder for everyone else is the goal, and to do that you need a swiss cheese model. Hopefully all the holes don’t line up between the layers to make it that much harder to get through. You aren’t plugging all the holes, but every layer you put on makes it a little bit harder.

    And NAT is not just simple to set up, it’s the intuitive base for the last 30 years of firewalls. I don’t see where you get a cost from it. As I said, separating network spaces with it comes naturally at this point. Maybe that’ll change, but I remember using routable IPV4 when it was it the norm, and moving to NAT made that all feel way more natural.
