Installation/Setup

Setting up Pi-hole is straightforward. Here’s a step-by-step guide:

  1. Prepare your hardware. A Raspberry Pi is commonly used, but Pi-hole can also run on other Linux-based systems.
  2. Install the operating system. For Raspberry Pi, use Raspberry Pi OS. Download it from the official website and flash it onto an SD card.
  3. Boot your Raspberry Pi and ensure it has network access.
  4. Open a terminal and install Pi-hole using the following command:
    curl -sSL https://install.pi-hole.net | bash

    This command downloads and runs the Pi-hole installer script.

  5. Follow the on-screen prompts to configure your Pi-hole installation. You’ll be asked to select an upstream DNS provider, among other settings.
  6. Once installed, access the Pi-hole web interface by navigating to http://pi.hole/admin from a device on your network.

Common issues during installation include network configuration errors and insufficient permissions. Ensure your user has the necessary privileges and that your network settings are correct.

Configuration

After installation, you can configure Pi-hole to suit your needs:

Editing Configuration Files

To edit Pi-hole’s configuration, you may need to modify the /etc/pihole/setupVars.conf file. Use a text editor like nano:

sudo nano /etc/pihole/setupVars.conf

Here, you can change settings like your DNS server, block lists, and more. Save your changes and restart Pi-hole with:

pihole restartdns

Advanced Customization

For advanced users, Pi-hole offers several customization options. You can add custom block lists by editing the /etc/pihole/adlists.list file:

sudo nano /etc/pihole/adlists.list

Add your desired block lists URLs, save the file, and update Pi-hole:

pihole -g

Security considerations include regularly updating your block lists and ensuring your Pi-hole is not exposed to the internet without proper safeguards.

Usage and Performance

Pi-hole provides real-time and historical data on DNS queries made by devices on your network. Access the web interface to view metrics and manage settings:

http://pi.hole/admin

Real-world examples of usage include monitoring blocked domains, adding custom DNS entries, and viewing query logs. This allows you to fine-tune your network’s security and ad blocking efficiency.

Advanced Tips

For those looking to get the most out of Pi-hole, consider these advanced tips:

Integrate with Unbound

Unbound is a DNS resolver that can add an extra layer of privacy. To set it up with Pi-hole:

sudo apt install unbound

Edit the Unbound configuration file:

sudo nano /etc/unbound/unbound.conf.d/pi-hole.conf

Add the following configuration:


server:
    verbosity: 1
    interface: 0.0.0.0
    access-control: 0.0.0.0/0 allow
    cache-max-ttl: 86400
    cache-min-ttl: 3600
    prefetch: yes
    num-threads: 4
    rrset-roundrobin: yes

Restart Unbound and configure Pi-hole to use it as the upstream DNS server:


sudo service unbound restart
pihole -a -i local

Enable DNS-over-HTTPS

For enhanced privacy, enable DNS-over-HTTPS (DoH). Install a DoH client like cloudflared:


sudo apt install cloudflared
cloudflared -v

Configure Pi-hole to use cloudflared as the upstream DNS server.

Common Issues/Troubleshooting

  1. Installation hangs: Ensure your device has a stable network connection and sufficient permissions.
  2. Web interface not loading: Verify that your device IP address is correct and Pi-hole service is running.
  3. DNS resolution issues: Check that Pi-hole is set as the primary DNS server on your network. Restart your router if necessary.
  4. Ad blocking not effective: Update your block lists and flush the DNS cache on your devices.
