  • the questions of can they spy, and will they spy are different questions. at some US ISPs (at least the one i am at) the modems usually are only monitoring performance, ie number of packets, errored and discarded packets for troubleshooting. as far as the modem which i will assume is just a layer 2 bridge to your provider, usually not a whole lot going on there due to costs of the hardware. where the privacy violations are going to occur in the access equipment or core. this is what your modem connects to, then your traffic crosses on the way to the “greater internet” if your not using a vpn to outside of your provider, there is no way around it, they can and probably do tap into what your doing. a lot of them it may not be overly nefarious, i know my company does not sell customer data, and we generally only access it for troubleshooting and bandwidth analysis for upgrades, or as ordered by a court for law enforcement.

    if you use a router from your isp almost every manufacturer is trying to sell all these different analytics and dpi that basically tells us what websites customers are visiting and how much/type of traffic to those sites, but directly from the router. same, or greater level of privacy violation as that can see local traffic on your lan, as well as watching wifi connection strength and scanning to see air quality and neighbors for “troubleshooting” or to sell access points.


  • make sure it’s configured for clean shut downs before your battery runs out, auto power up on restoration, and hope it doesn’t happen. you will eventually have an outage that outlasts your batteries.

    I have a large string of batteries from an old telco office, that runs my rack for 14hrs (calculated, I shut everything down around this time) and that did not last for the 2-3 day outage we had after a storm. Without a generator, you will inevitably have an outage, but if you are prepared, then you can mitigate any damage. use NUT if you need to shutdown or power multiple devices from one monitored UPS

    i didn’t downvote but 17v on a 12v battery maybe seems a bit high. I’m more used to about 7-14% over (maybe up to 14v on a 12v batt) when charged/floating but i don’t use solar anywhere currently, and i usually work on 48v systems. i normally expect to see about 54v on a fully charged battery string (13.5v per battery x4) with the rectifiers running.

    i also second the opinion of running an automotive PSU for this situation.

    edit: i looked it up since i was curious, some “12v” solar panels can output between 16-20v, but it’s recommended that you would use a charge controller, especially if you have lead-acid batteries





  • i buy my domains from namecheap but i use cloudflare for name servers (free tier, dns only for everything) and have ddclient (or whatever the newest version is called now) which runs on my router. my current settings only update cloudflare when the interface changes, and then update time after the change is about 15 minutes for propagation. i work in the network department of my isp so my address doesn’t change often, but the isp side of my setup is identical to any other subscriber. i use opnsense, but also manage a very small pfsense box that this works on as well. i update ipv4 dynamically, but not ipv6 yet, but i will.



  • as someone who does stuff in my lab that can translate to a work context, i absolutely second this opinion.

    if i am labbing to learn, then learning the best way to do it is always be the main focus, even if it means restarting what I was doing to change how some prerequisite is setup or functions.

    today, OP is working with jellyfin, but as an example, what happens if later they get security cameras and want to use some sort of local ML to analyze events, and don’t want to put a lot cpu utilization to that task during lulls in activity? a solution might be to dynamically create and destroy containers for the analysis tasks, and the background on a network setup in an unrelated container stack that would allow scaling that means one less problem to solve later.
