# Project 1: Home Lab Setup

## Project Overview
This project documents the setup of a basic home lab environment using VirtualBox and Ubuntu Server 22.04 LTS.

## Environment Details
- **Host System**: Windows 11
- **Hypervisor**: Oracle VirtualBox
- **Guest OS**: Ubuntu Server 22.04 LTS
- **Resources Allocated**:
  - CPU: 2 cores
  - RAM: 2GB
  - Storage: 20GB
  - Network: NAT + Host-only adapter

## Setup Steps

### 1. VirtualBox Installation ✅
- Successfully installed VirtualBox
- Created project directory structure

### 2. Ubuntu Server VM Creation ✅
- [x] Download Ubuntu Server 22.04 LTS ISO
- [x] Create new VM in VirtualBox
  - [x] Configure VM settings (CPU, RAM, Storage)
  - [x] Configure network adapters
- [x] Install Ubuntu Server
  - [x] Basic system configuration
  - [x] Network setup

### 3. Network Configuration ✅
- [x] Configure NAT adapter for internet access
  1. Verify IP address configuration ✅
  2. Test internet connectivity ✅
     ```bash
     ping 8.8.8.8      # Success
     ping google.com    # Success
     ```

- [x] Configure Host-only adapter for direct host communication
  1. Verify second network interface ✅
     ```bash
     ip addr show enp0s8
     # Output shows:
     # inet 169.254.0.2/16 brd 169.254.255.255 scope global enp0s8
     ```
  2. Test host connectivity ✅
     ```bash
     # Successfully pinged host (169.254.167.242)
     # Round-trip time (RTT) avg: 2.846ms
     ```

- [x] Document network configuration:
  - NAT adapter IP (enp0s3): 10.0.2.15/24
  - Host-only adapter IP (enp0s8): 169.254.0.2/16
  - Default gateway: 10.0.2.2
  - Host IP: 169.254.167.242

### Current Status
- ✅ NAT adapter: Working (Internet access)
- ✅ Host-only adapter: Working (Host communication)
- ✅ Network connectivity: Verified

### Next Steps
Now that networking is configured, we can proceed to:
1. Basic Security Setup
   - [x] Create non-root user with sudo privileges
   - [x] Configure SSH access
   - [x] Set up UFW firewall

### 4. Basic Security Setup ✅
- [x] User Management ✅
  - Created sysadmin user with sudo privileges
  - Enhanced hugh user security
  
- [x] SSH Configuration ✅
  - Installed and configured OpenSSH server
  - Implemented key-based authentication
  - Disabled password authentication
  - Applied security hardening settings

- [x] UFW Firewall Setup ✅
  - Installed and configured UFW
  - Set default policies (deny incoming, allow outgoing)
  - Allowed required services:
    - SSH (port 22)
    - HTTP (port 80)
    - HTTPS (port 443)
    - Host machine access (169.254.167.242)
  - Verified connectivity

### 5. System Monitoring and Maintenance ✅
- [x] Monitoring Tools
  - Installed and configured htop
  - Set up Netdata for system metrics
  - Configured Logwatch for log monitoring
  
- [x] Maintenance Procedures
  - Implemented backup strategy with rsync
  - Configured automated updates
  - Set up log rotation

### Current Status
