Linux DNS Change Script

A simple Bash script to change the DNS settings on your system. This script allows you to select a predefined DNS server from a list and updates the /etc/resolv.conf file accordingly. It also handles scenarios where the resolv.conf file is managed by systemd-resolved.

Features

  • Select from a list of predefined DNS servers.
  • Automatically detects if /etc/resolv.conf is a symlink and unlinks it.
  • Creates a new /etc/resolv.conf with the selected DNS server.
  • Simple and user-friendly interface.

Supported DNS Servers

  1. Shecan: 178.22.122.100
  2. 403: 10.202.10.202
  3. Electro: 78.157.42.100
  4. Radar_Game: 10.202.10.10
  5. Google: 8.8.8.8

Requirements

  • Bash shell
  • sudo privileges to modify /etc/resolv.conf

Usage

  1. Clone this repository to your local machine:

    git clone https://github.com/RadinPirouz/DNS_Changer/
cd DNS_Changer

  2. Make the script executable:

    chmod +x dns.sh

  3. Run the script:

    ./dns.sh

  4. Follow the prompts to select your desired DNS server.

Notes

  • This script is intended for Linux systems where /etc/resolv.conf is used for DNS resolution.
  • Use caution when modifying network settings, especially on production systems.
