Automatic Setup (CLI)

Want to spend the least amount of time setting up Control D on a Linux device or looking to do a scripted deployment? Have no fear, there is an app for that.

Command Line Daemon is what you're looking for.

Manual Setup

Want to update the DNS server in your favorite Linux distro? Well, there are only about 20 ways to do it. But in all seriousness, if you require a tutorial to do this, it may be a better idea to use the Automatic Setup method. It abstracts the setup to a single command.

We'll briefly go over some common ways to update DNS.

systemd-resolve

If you are running a version of Linux that uses systemd-resolved, you can likely configure DNS-Over-TLS on it.

Open Terminal and edit your resolved.conf file

nano /etc/systemd/resolved.conf

Premium Resolvers

Update your config as follows if you are using a custom premium resolver. abcd1234 will be different for you.

[Resolve]

DNS=76.76.2.22#abcd1234.dns.controld.com

DNSOverTLS=yes

The value of DNS after the # will be your DNS-over-TLS resolver for the chosen Endpoint.

Save the file and restart the systemd-resolve service.

Free Resolvers

Update your config templating DNS after the # to the DNS-over-TLS hostname for the desired free resolver.

[Resolve]

DNS=76.76.2.11#p2.freedns.controld.com

DNSOverTLS=yes

The above example assumes the Malware and Ads blocking resolver.

Save the file and restart the systemd-resolve service.

stubby

If you're using stubby, edit the config file.

sudo nano /etc/stubby/stubby.yml

Find round_robin_upstreams and set this value to 0.

Then search for DEFAULT UPSTREAMS and and comment out all of them. Then add a new config block.

Premium Resolvers

Add the following entry to your config file.

- address_data: 76.76.2.22
  tls_auth_name: "abcd1234.dns.controld.com"

The value of tls_auth_name will be your DNS-over-TLS resolver for the chosen Endpoint (abcd1234 will be different for you). If you need additional backup IPs or IPv6, refer to Control D IP Ranges.

Save this file and restart stubby.

Free Resolvers

Add the following entry to your config file.

- address_data: 76.76.2.11
  tls_auth_name: "p2.free.controld.com"

The value of tls_auth_name will be the desired free resolver DNS-over-TLS hostname. The above example assumes the Malware and Ads blocking resolver. If you need additional backup IPs or IPv6, refer to Control D IP Ranges.

Save this file and restart stubby.
