Linux DNS Setup

Static IP address

1. Navigate to the SafeDNS Dashboard > Settings and copy your IP address in the "Enter an IP address or DynDNS" box. Click "Add".

2. 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.

Open the settings of the current Network Interface.

Add SafeDNS servers: 195.46.39.39 and 195.46.39.40.

Please note, that servers must be separated by a comma.

Otherwise, you need to find out which application is used for the network settings and add SafeDNS servers there.

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

1. 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:

2. 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.

Open the settings of the current Network Interface.
