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 ✅

Download Ubuntu Server 22.04 LTS ISO
Create new VM in VirtualBox
- Configure VM settings (CPU, RAM, Storage)
- Configure network adapters
Install Ubuntu Server
- Basic system configuration
- Network setup

3. Network Configuration (In Progress)

Configure NAT adapter for internet access
1. Verify IP address configuration:
```
ip addr show
```
2. Test internet connectivity:
```
ping 8.8.8.8
ping google.com
```

Configure Host-only adapter for direct host communication

Verify second network interface:
```
ip addr show
```

Test host connectivity:

# From Ubuntu VM - ping your Windows host IP
ping <windows-host-ip>

# From Windows host - ping your Ubuntu VM IP
ping <ubuntu-vm-ip>

Document network configuration:
- NAT adapter IP: _____________
- Host-only adapter IP: _____________
- Default gateway: _____________
- DNS servers: _____________

4. Basic Security Setup (Pending)

Create non-root user with sudo privileges
Configure SSH access
Set up UFW firewall
Implement basic security hardening
