  • Can I run Pi-Hole on my Z-Net?

    I'm not sure what to say that isn't covered in the title of the thread. Does anyone have any experience or thoughts on the matter?

    I do have a Z-Net and a Pi-Hole. The Z-Net is still running bone stock as a Raspberry Pi Model B+. My Pi-Hole is a Pi3.

    Personally, I wouldnt risk slowing down my lighting control for DNS, or vice-versa. The Pis are so cheap power efficient, you might be better off having them separated.

      Can I run Pi-Hole on my Z-Net?

      I would say that it depends on how loaded your z-net is. I would run HTOP to get a better idea of system resource utilization.

      Here I run PFSense as my home firewall. I have a local DNS server hosted on PFSense. Also, I have been running PFBlockerNG for some time on the recommendation of @Pete.

      In PFBlockerNG you can block by world region, which I did for a while. I kept finding destinations and sources that would get blocked and have to be white listed. What's more there are enough domestic sources of malicious attack that I would end up missing. I opted to take a different approach. PFBlocker supports custom IPv4 IPv6 and DNSBL lists.

      Custom IPv4/IPv6 lists allow me to policy out IP communication to and from my firewall. I added a handful of black lists I trust there and opted to block communication to and from them.

      DNSBL allows you to filter DNS requests with a black list. I added the feeds that Pi-holes uses here as well as a few other reputable ones I have used in the past.

      So this gives me the same feature set using as Pi-hole in my existing PFSense firewall.

        Here is an example way to show utilization of different stuff on your ZNet.

        Here using an RPi2 running a few things including ZWave.

        It is running ser2net, OWFS, Digitemp and Domoticz. Initially I wanted to look at the chit chat on the network.

        I type sudo lsof -i -P -n | grep LISTEN

        Then install htop

        sudo apt-get install htop

        Watch it and use the filter to separate out application use:

        Here is ser2net viewing with htop

        Here is owfs utilization:

        Here is Domoticz utilization: (Domoticz is a LUA based automation program).
