  • I had a post a while back about what I was doing to cut costs.

    • TLP: Adjusts CPU frequency scaling, PCI‑e ASPM, SATA link power‑management
    • Powertop: Used to profile power consumption and has a tune feature sudo powertop --auto-tune
    • cpufrequtils: Used to manage the CPU governor directly
    • logind.conf: Can be used to put the whole server to sleep when idle

    After doing all of that, which does help out during operational hours, I decided to save 10-12 hours of consumption by just shutting it down. The old ‘turn the light out if you’re not in the room’ concept. Right now I am manually booting the server, and it doesn’t take that long to resume operations. However, why not employ some automation and magic packets to fire it back up in the morning.

    ETA: I do have a watt meter on the server.



  • I finally installed my wife

    Man…technology has come a long way.

    Nothing here to write home about. A couple of minor tweaks to the network, and blocking even more unnecessary traffic. I’ve been on a mission to reduce costs in consumables such as electricity. I have a cron that shuts everything down at a certain time in the evening, and am working on a WOL routine fired by a cron from my stand alone pfsense box, to the server, to crank it back up in the morning just before I get up. It seemed to be the lowest hanging fruit so I have it on priority. It just didn’t make sense to run the server for 10 - 12 hours on idle I don’t have any midnight mass downloads of Linux iso’s nor do I make services available to other users so, it seemed to be a good place to start. I guess, by purist’s standards, it’s not a server anymore but an intermittent service, but it seems to be working for me. Will check consumption totals at the end of the month.

    Other than that, I haven’t added anything new to the lineup, and I am just enjoying the benefits.





  • It wouldn’t be a bad idea. Right at this moment my temps are as such:

    • dev.cpu.0.temperature: 103 °F
    • dev.cpu.1.temperature: 103 °F
    • dev.cpu.2.temperature: 105 °F
    • dev.cpu.3.temperature: 109 °F
    • hw.acpi.thermal.tz0.temperature: 81 °F

    IIRC, the case temp is like 194 freedom units. I’ve never really seen it get much higher than it is now.







  • A hardware firewall generally indicates a standalone appliance that is dedicated to being a firewall. Not to be confused with a software firewall as you would see with UFW, or Windows Defender. Modern routers do possess some of the same tenets of a hardware firewall, but a dedicated hardware firewall usually gives a broader range of defenses such as IDS/IPS, filtering, etc.

    I have a dedicated hardware firewall in the form of pFsense. The ‘black box’ in OP’s picture is the hardware firewall.
