Let’s start this thread by detailing what my RPi setup is like. I currently have a Raspberry Pi 2 that is running pihole for network-wide ad blocking. I’m always surprise at how much is internet traffic is blocked every day, some expect and others unexpected.
Don’t know about pihole? Read up about it here.
Hey 
Yeah, Pi-Hole is great.
I’m still surprised as well. Such a good software to block all the ads and not only for blocking ads, but also for blocking ‘calling home’ devices. I have one device here which is ‘calling home’ every 30 seconds …
All the network is going through the Pi-Hole. If you use a VPN server you can even block the ads for other devices like an iPhone.
Server:
I have a raspberry 2 which I’m using for the Arch Linux | ARM server. I added a bit more for my server. Maybe one day we will share another image with the other software included.
