# Configuring Linux Mint to use Lumiun DNS via DoT

## This configuration will cause Linux Mint to forward DNS requests to Lumiun DNS, using the secure DoT (DNS-over-TLS) protocol. The configuration is done through the Unbound software.

In this article, we will cover configuration on Linux Ubuntu. If you use Linux Ubuntu, see this [other article](https://help.lumiun.com/en-us/hc/configurando-linux-ubuntu-para-usar-lumiun-dns-via-dot?hsLang=en-us).

### Step-by-step

1. Open a Terminal (local or ssh).
2. Copy and paste the parameters below - Change **abcd1234** to your site ID, and also change **dns\_server\_1**, **dns\_server\_2**, **dns6\_server\_1**, and **dns6\_server2** to your site's respective DNS servers. All of these are listed on the [sites](https://dns.lumiun.com/sites) page.
   
   ```
   sudo apt update ; sudo apt -y install unbound curlsudo bash -c "curl -o /etc/unbound/cacert.pem https://curl.se/ca/cacert.pem"sudo bash -c "cat << EOF > /etc/unbound/unbound.conf.d/lumiundns.conf server:  interface: 127.0.0.5  tls-cert-bundle: /etc/unbound/cacert.pem  forward-zone:    name: '.'    forward-tls-upstream: yes    forward-addr: dns_server_1#abcd1234.dot.ldns.io    forward-addr: dns_server_2#abcd1234.dot.ldns.io    forward-addr: dns6_server_1#abcd1234.dot.ldns.io    forward-addr: dns6_server_2#abcd1234.dot.ldns.ioEOF"sudo systemctl restart unboundsudo systemctl stop systemd-resolvedsudo systemctl disable systemd-resolvedsudo rm /etc/resolv.confsudo bash -c "echo nameserver 127.0.0.5 > /etc/resolv.conf"nslookup www.google.com
   ```
3. Execute.

That's it! You can now view [reports](https://dns.lumiun.com/relatorios) on your Lumiun DNS dashboard and also define [policy](https://dns.lumiun.com/politicas) rules.
