PiHole Set-Up

Equipment

  • Already had most of the things required, needed:
    • Micro-USB to Ethernet cable
    • microSD card
    • Short Ethernet cable

Setting up the Raspberry Pi

  • Download Raspbian Lite image (for the time being, we only want to use this for PiHole)
  • Flash onto microSD with Etcher
  • Plug everything in
  • Cock-up 1: Raspbian now disables SSH by default. Need to plug in a screen
  • Change the default password on activating SSH (we’ll fix this later but it’s still good to get this done early)
  • Shutdown, unplug screen etc, set up cables as actually desired and re-plug in
  • SSH in!
  • Run updates (sudo apt-get update, sudo apt-get upgrade), reboot
  • Set up SSH

    $ cd ~
    $ mkdir .ssh
    $ cd .ssh
    $ nano authorized_keys
    
  • Use PuTTYgen to generate keys

  • Cock-up 2: PuTTYgen’s default public key is in an incompatible format.

    • Delete first two rows and last row
    • Add ssh-rsa before the key
    • Delete all carriage returns
  • Reboot to check it works

  • Remove password authentication

Installing PiHole

  • curl -sSL https://install.pi-hole.net | bash
  • Change from the default web admin password with pihole -a -p
