Linux Setup Guide

Configuring your Linux system to use our public DNS resolvers enhances security, privacy, and browsing speed. Follow these steps to manually set up DNS on Linux.

Method 1: Temporary DNS Change (Valid Until Reboot)

1. Open Terminal.

2. Run the following command to set the DNS servers:

   sudo systemd-resolve --set-dns=209.250.227.42 --interface=eth0
   sudo systemd-resolve --set-dns=209.250.227.42 --interface=wlan0
   

   Replace eth0 or wlan0 with your active network interface.

3. Verify your new DNS settings:

   resolvectl status
   

Method 2: Permanent DNS Change (Using resolv.conf)

1. Open Terminal.

2. Edit the resolv.conf file:

   sudo nano /etc/resolv.conf
   

3. Replace existing nameservers with:

   nameserver 209.250.227.42
   nameserver 64.176.190.82
   

4. Save and exit the file (CTRL+X, then Y, then ENTER).

5. Lock the file to prevent automatic overwrites:

   sudo chattr +i /etc/resolv.conf
   

Method 3: Changing DNS via NetworkManager

For systems using NetworkManager (Ubuntu, Fedora, etc.):

1. Open Terminal.
2. Run the following command:

   nmcli con mod "Your_Connection_Name" ipv4.dns "209.250.227.42 64.176.190.82"
   

3. Restart NetworkManager:

   sudo systemctl restart NetworkManager
