This blog entry summarizes the needed steps (may be not all) how to setup the popular Add-ware blocker Pi-Hole on the Turris Omnia appliance.
Prerequsites
Turris Omnia with OS version 3.7 or higher
At least completion of the initial setup (first run)
Container Setup
SSH into the box
Create a new lxc container:
1
lxc-create -t download -n pi-hole
When prompted, enter the following parameters: ubuntu xenial armv7
Configure a static IP address to be set as new DNS server in a further step:
1
2
3
4
5
vi /srv/lxc/pi-hole/config
# Append the following lines:
lxc.network.ipv4.ipv4 = <static ip address>/<mask bits>
lxc.network.ipv4.gateway = <router address>
Configure the container to be started automatically (after reboot):
1
2
3
4
5
6
vi /etc/config/lxc-auto
# Add or append the following lines
config container
option name pi-hole
option timeout 60
Start the newly created lxc container:
1
lxc-start -n pi-hole
Verify if the container is up and running:
1
lxc-info -n pi-hole
Pi-Hole Setup
Attach to the container:
1
lxc-attach -n pi-hole
Install needed package:
1
apt install -y wget
Download the Pi-Hole installation script and run it:
Follow the script’s interactive installation instructions (correct settings should be suggested by the installation assistant)
Set a password in order to login over the admin web console:
1
pihole -a-p somepasswordhere
As a first test, try to open the Pi-Hole URL http:///admin in a new browser window:
Turris Setup
Login to LuCI
Go to Network interfaces > LAN > DHCP Server > DHCP Option and change IP to the pi-hole container’s static IP
Verification
Ensure your IP address lease has been renewed on the client from where you are connected to the Turris Omnia box (in order to use Pi-Hole as the DNS server)
Open the Pi-Hole Add-ware testing page in a new browser window: https://pi-hole.net/pages-to-test-ad-blocking-performance/
