Has anyone any experience with "pi-hole"? (
https://pi-hole.net/).
I'm pretty intolerant of ad's, and for sometime have been using
https://github.com/StevenBlack/hosts. This constructs
a gigantic /etc/hosts, in which thousands of dns names are "/dev/null"d. This has not been problem-free.
Then I came across pi-hole, and installed it on a (3B) pi that I was using as a cups server for some ancient non-wifi printers,
and doing little else. I put this top of the DNS servers for a machine or two, just out of curiosity. So far, I'm quite
impressed. For one thing, I can allow a handful of sites (like kitz.co.uk, sndbforums.com, ..) to show me ads, in the hope that
it thereby might bring them in a few pennies. There's a nice admin-page (it sets up a lighttpd server) where you can configure such things.
I can now see some unobtrusive ads on the kitz sites, and elsewhere.
I've only been using it a day or two. It's quite crisp, given that the pi involved has fallen down behind an immensely heavy metal filing cabinet,
and has rather dodgy wifi accessibility. I wondered about getting another lower-specced pi, ethernet connected to my router, and powered
via a router USB port. It doesn't seem to need a 3B.
Does anyone here use a pi-hole "in anger"? Any gotchas? Advice?
