Linux DNS Setup
The first step is the same for both Static and Dynamic IP address configurations: change your system’s DNS servers to SafeDNS addresses - 195.46.39.39 and 195.46.39.40
If you configure the network through NetworkManager, it will be sufficient to add SafeDNS servers there.
1. Open the settings of the current Network Interface.
2. Add SafeDNS servers: 195.46.39.39 and 195.46.39.40.
Please note, that servers should be separated by a comma.
Otherwise, you need to find out which application is used for the network settings and add SafeDNS servers there.
Static IP address
Your Linux device is now filtered with the SafeDNS filtering policy.
Please note that settings take 5-7 minutes to apply.
Stats and filtering status update every 10 minutes.
Dynamic IP address
Install and configure ddclient.
ddclient package is shipped with most Linux distributions.
If your Linux distribution doesn’t have ddclient, you can download it from GitHub.
After ddclient is installed, you need to insert the next configuration in its config file (/etc/ddclient.conf or /etc/ddclient/ddclient.conf):
daemon=300
syslog=yes
ssl=yes
protocol=dyndns2
server=www.safedns.com
use=web
web=http://www.safedns.com/nic/myip
# Replace with your email and password for www.safedns.com
login=you@yourmail.com
password=your_password
# Enter any name for your device.
# If you have several computers with dynamic IPs their names must differ.
laptop
Reboot your device and start ddclient.
If the similar string is shown in the system logs (/var/log/syslog, /var/log/daemon.log or /var/log/messages), ddclient is successfully configured:

Your Linux device is now filtered with the SafeDNS filtering policy.
Please note that settings take 5-7 minutes to apply.
