Linux Administration Fundamentals

This project demonstrates practical Linux administration skills developed in a Kali Linux virtual machine. The focus was on file management, permissions, users and groups, networking, system logs, Nano, and process management.

Project Overview

This hands-on lab focused on practical Linux administration rather than theory, building skills used daily by Linux administrators and SOC analysts.

Why I Built This Lab

I built this lab to gain confidence using the Linux command line through practical exercises that mirror real-world administration tasks.

Lab Environment

Project Objectives

  1. Practice Linux commands.
  2. Manage files and directories.
  3. Search files and text.
