Dynamic to Static IP Configuration Script for Ubuntu Server 24.04

Overview

This Bash script is designed to simplify the process of changing a dynamic IP address to a static IP address on Ubuntu Server 24.04.
It provides a comprehensive step-by-step walkthrough, making it user-friendly for individuals with limited technical expertise but need their Ubuntu server up and running with a static IP configuration.

Features

• Welcome Message: Provides an initial greeting and a brief overview of the script’s functionality.
• User Authentication: Displays the current user executing the script and prompts for confirmation to proceed.
• Network Interface Detection: Identifies an active network interface (ensure only one connection/ethernet cable is plugged in).
• Current Network Settings: Retrieves and displays the current IP address, netmask, gateway, and checks the status of DHCP4 and DHCP6.
• User Input Prompts: Prompts the user to enter a new static IP, netmask, gateway, DNS servers, and hostname.
• Netplan Configuration Management: Locates the existing netplan configuration file, creates a backup, and generates a new configuration file based on user input.
• Apply Configuration: Prompts the user to apply the new netplan configuration. If the user chooses not to apply, the script reverts to the original configuration and terminates.

Usage

1. Run the Script: Execute the script as root on your Ubuntu Server 24.04.
2. Follow the Prompts: The script will guide you through each step, from detecting the current network settings to applying the new static IP configuration.
3. Confirmation: Confirm the changes to apply the new configuration or revert to the original settings if needed.
