🚀 Privacy DNS Chooser Script v1.0 "Snow Breeze" Release!

Project source code : https://github.com/rollsicecream/privacy-dns-chooser

Dear Community,

I'm thrilled to announce the official release of the Privacy DNS Chooser Script v1.0, code-named "Snow Breeze"! This marks a significant milestone in my journey to simplify the process of enabling DNS-over-TLS with privacy-focused DNS providers on Linux systems using systemd-resolved.

Key Highlights:

  • User-Friendly Setup: Easily configure DNS-over-TLS with a seamless and intuitive CLI Interface
  • Privacy-Focused Providers: Choose from trusted DNS providers like Quad9, Mullvad DNS, and NextDNS (more coming soon!)
  • Enhanced Security: DNS-over-TLS is enabled by default for a more secure online experience.

How to Get Started:

  1. Ensure you have systemd-resolved installed on your Linux system.
  2. Download the script from GitHub.
  3. Run the script with sudo to set up your preferred DNS provider.

That is neat! It is a specific response so it should work.

#!/bin/bash

# Function to set insecure DNS
function insecure-dns() {
  # Backup the original resolved.conf file
  cp /etc/systemd/resolved.conf /etc/systemd/resolved.conf.bak

  # Modify resolved.conf to disable custom DNS, DoT, and DNSSEC
  sed -i 's/^DNS=.*/#DNS=/; s/^Domains=.*/#Domains=/; s/^DNSOverTLS=.*/#DNSOverTLS=/; s/^DNSSEC=.*/#DNSSEC=/' /etc/systemd/resolved.conf

  # Restart systemd-resolved
  systemctl restart systemd-resolved
}

# Function to set secure DNS
function secure-dns() {
  # Restore the original resolved.conf file
  mv /etc/systemd/resolved.conf.bak /etc/systemd/resolved.conf

  # Restart systemd-resolved
  systemctl restart systemd-resolved
}

while true; do
  response=$(curl -sI captive.test.com | head -n 1 | cut -d' ' -f2)

  if [ "$response" == "200" ]; then
    insecure-dns
    xdg-open captive.test.com
    sleep 30
    # something to wait until window is closed, otherwise spam!
  else
    secure-dns
  fi

  sleep 5
done

This should work. What would be needed is to track the process of the login and only continue when the window is closed again.

From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.
