Introduction

Knoppix is a powerful Linux distribution that runs from a live CD or USB. This project provides a comprehensive guide on how to install Knoppix OS in a virtual machine. It also dives into the implementation of the getppid system call, offering insights into how processes interact in Linux.

Getting Started

Prerequisites

Before you begin, ensure you have the following:

• A computer with virtualization support.
• Virtualization software such as VirtualBox or VMware.
• Basic knowledge of Linux commands.

Installation Steps

1. Download Knoppix ISO: Visit the official Knoppix website to download the latest ISO file.
2. Set Up Virtual Machine:
   • Open your virtualization software.
   • Create a new virtual machine.
   • Allocate memory and disk space as needed.
   • Load the Knoppix ISO as the boot disk.
3. Boot the Virtual Machine: Start the virtual machine and follow the on-screen instructions to install Knoppix.
4. Explore the System: Once installed, you can explore Knoppix and its features.

For detailed installation instructions, refer to the Releases section.

Understanding System Calls

What is a System Call?

A system call is a way for programs to request services from the operating system's kernel. System calls provide an interface for applications to interact with the hardware and manage resources.

The getppid System Call

The getppid system call returns the process ID of the parent process. This is useful for processes that need to know their parent, such as when managing child processes.

Example Usage

#include <stdio.h>
#include <unistd.h>

int main() {
    pid_t ppid = getppid();
    printf("Parent Process ID: %d\n", ppid);
    return 0;
}

Virtual Machines

Why Use a Virtual Machine?

Virtual machines allow you to run multiple operating systems on a single physical machine. This is ideal for testing, development, and educational purposes.

Setting Up a Virtual Machine

1. Choose Your Virtualization Software: Popular options include VirtualBox, VMware, and Hyper-V.
2. Install the Software: Follow the installation instructions for your chosen software.
3. Create a New Virtual Machine: Allocate resources and load the Knoppix ISO.
4. Start the Virtual Machine: Boot from the ISO and follow the installation steps.
