  • As long as you’re using a slower release cycle, ie something like Debian, then you shouldn’t need to be concerned.

    I think anyone riding the crest of the wave with Arch (& esp. the AUR) would likely be aware that things break, so, supply chain attacks are likely to be seen here quicker.

    I honestly wouldn’t be surprised if PPAs had similar issues, but might take longer to be noticed.

    Personally, I have a lot of Ansible building my stuff, so actually rebuilding things wouldn’t be an issue, but, would I then be installing everything with all the current latest malware…?







  • DNS… set your system up to use an external DNS provider like OpenDNS where you can select categories to block.

    I used this to block adult, gambling, malware, etc at the grandparent’s house when the kids were growing up and starting to search the internet for school homework, etc.

    If it’s done in the router you’ll cover all devices and you give someone else the password, so you can’t change it.






  • No, I was referring to a separate DMZ host…

    Physically separate firewall connection, with different firewall policies between internet<–> DMZ than DMZ <–> internal network.

    Not a VLAN. VLAN Hopping makes it possible to jump between VLANs, so they should only be consided as an administration tool, not a security mechanism.

    But, I agree with you, putting a device on the internet isn’t something that anyone should do without understanding the technical issues.


  • Kinda overlapping other replies, but to answer your question: A = your external IPv4 address

    The rest could be empty AAAA = an external IPv6 address NS = a DNS server MX = Mail Server

    TXT is just text, but it can be used by, ie Lets Encrypt to prove you own that domain for your SSL certificate

    If you open TCP 80 / 443 on the open internet EVERYONE will probe you, but you want to run a Friendica server, so you kinda need that (disclaimer: I do not know how Friendica is setup)

    So, you’ll need something (firewall, Fail2Ban, etc) to protect your server whilst also allowing it to federate to other servers.

    I’d strongely suggest you put your server on a VPS with a provider that has some level of defense already setup for you.

    I wouldn’t run this in your home network with putting it into a DMZ of some kind.





  • Getting it up & running is just loading their software onto a Pi SD card, so easy

    I recall there was a bit of a faff learning how it creates “feeds” from sensor data - it’s just different, not complex, but took a couple of attempts to get it how I wanted it (which included some calibration of the sensors… I recall it was reporting a few W of solarpower at night)

    But… since then it’s been running for years with a few updates, so really stable.

    Then HA came along, and there’s an integration that pulls the data in, so I can see grid & solar power…

    Perhaps I wasn’t clear at the beginning though - I don’t have batteries (yet…), so I’m not montioring that, but I am presume it would be a similar process. I just didn’t want you to purchase something without checking it fits your exact needs first.

    Have a search / post on their forum, they’re really friendly there and someone might have already discussed this…
