  • I clearly don’t know enough about reverse ssh connections.

    My understanding is that you tell the VPS to connect to your computer, a shell pops up on your end, and commands run in it will control the VPS. It helps get around firewalls and makes it less obvious to defenders that an attacker has control of a box because it’s not an inbound connection, it’s an outbound connection.

    What’s your workflow? So you ssh into the VPS and maybe use Tmux or Screen to connect to a terminal session, that session is connected to your home machine but instead of sending commands back to the VPS, it sends commands to your home computer?


  • But ultimately, it turns out I like interesting technical problems, learning things, and buying stuff I don’t need off the internet - more than chatting to people I don’t know.

    This is exactly why I’ve never taken a legitimate look into the hobby. I think I’ll keep admiring from afar until I find a good use for it

    received images directly from the amateur station on the ISS

    This concept makes sense but I always assumed ham radio was just about audio. That’s pretty cool

    So now I’m more into Linux and self-hosting

    You probably know about this already but just in case, since you have an interest in radio and you have experience with antennas, you might have a cool project that could benefit from LoRa. There’s a few open source projects that incorporate the tech to make sensors for crops or messaging friends at festivals when cell towers are overloaded





  • I have one pi (rpi 4b) that I still use. I have it in an Argon One V2 case for the daughter board that lets me boot from an M.2 SATA SSD. I got tired of the corrupted SD cards. It’s actually reliable now.

    Anyway, I mainly only use it because in the event of a power outage, as soon as power is restored, it automatically turns on. If I’m not home, I can SSH back into my network and send a WoL packet to my actual server to turn it back on.

    The pi also runs:

    • Scrypted so I can view my ring cameras in the Apple Home app and so I get the “someone is at the door” notifications on my Apple TV
    • Pi-Hole
    • Pi-VPN







  • Imagine you need to go see your doctor. They work in a building with 65535 rooms. Some rooms are empty. Some rooms have people in them that provide different services. But you need your doctor so you look up their location.

    You learn the building address (IP address) and the room number (port)

    In practice, you attach services to specific ports so that other computers can access those services. Typically, http traffic is on port 80 and https is on port 443. So if you visit a website, you are likely connected to a server on one of those two ports. But it’s not a requirement. You could create a website and put it on port 2097, or 532, or 47210; it doesn’t matter.
