Host your own DNS, now with 100% more ad block!
One of your essential addons for your web browers is almost definitely some sort of ad blocker. Resources like bandwidth are a precious resource, especially when your ISP is of the many that limit it on a monthly basis. Another great benefit of having ad blocking software is that you risk a much lower chance of being infected by drive by malware, served by ads themselves. Not loading ads also means.. less loading! Why don’t we take the load off our machines even less by removing our ad block extensions?
For what you’ll see in this tutorial, it is assumed you’re working with a clean Debian 8.0 template. First off, we’ll use apt to install dnsmasq, the only requirement for this to work, and tell it to start by default.
apt-get update && apt-get install dnsmasq -y
update-rc.d dnsmasq enable
We’re going to delete dnsmasq’s default configuration file, as it’s way too cluttered for what we’re using it for. After that, we’ll be making our own, much simpler version.
rm /etc/dnsmasq.conf
nano /etc/dnsmasq.conf
**dnsmasq.conf
**
bogus-priv
domain-needed
no-resolv
server=8.8.8.8
server=8.8.4.4
interface=venet0:0
listen-address=127.0.0.1
cache-size=10000
addn-hosts=/etc/pihole/gravity.list
host-record=hostname,127.0.0.1,::1
For options like _interface_, you’ll need to use ifconfig to see what interface lists the IP you want it to be setup on. For _host-record_, simply run `hostname` to know what you should put. What is pihole you might ask? https://pi-hole.net is an open source project written by Jacob Salmela to do the exact same thing we’re doing, but for Raspberry Pi’s on your local network. Creating a blacklist for ads would take ages, so we’re going to take advantage of Pi-Hole’s already created list.
wget https://raw.githubusercontent.co ... e/master/gravity.sh
chmod +x gravity.sh
./gravity.sh
gravity.sh will start populating an extensive blacklist for ad networks, but it shouldn’t take long. Finally, we’ll use sed to change every instance of our virtual machine’s IP with a blackhole, and restart dnsmasq.
sed -i “s/^[0-9\.]\+\s/0.0.0.0 /g” /etc/pihole/gravity.list
service dnsmasq restart
You’re done! I like to take it a step further though, and automate the updating of our blacklist.
apt-get install cron -y
crontab -e
At the bottom of our crontab, enter the following, which will set our blacklist to be updated once every day.
0 5 * * * bash /root/gravity.sh
