A complete Linux cluster setup with Slade as the master desktop controller and 4 worker nodes, featuring animated welcome screens and real IP connectivity.

• Slade Master: Desktop Linux with GUI, controls all worker nodes
• Worker Nodes 1-4: Headless servers controlled by Slade
• Real IP: Public network bridge for internet access
• Private Network: Internal cluster communication

• VirtualBox (hypervisor): https://www.virtualbox.org/wiki/Downloads
• Vagrant (VM automation): https://developer.hashicorp.com/vagrant/downloads
• Minimum System: 8GB RAM, 4 CPU cores (for full cluster)
• Network: Bridged adapter capability for real IP

Install VirtualBox first, then Vagrant. Reboot if either installer asks you to.

cd /path/to/vProfile-Ubuntu
vagrant up slade

vagrant ssh slade

vagrant up worker1 worker2 worker3 worker4

vagrant up

Once connected to Slade master, use these commands:

# Connect to worker nodes
connect-worker1    # SSH to Worker Node 1
connect-worker2    # SSH to Worker Node 2
connect-worker3    # SSH to Worker Node 3
connect-worker4    # SSH to Worker Node 4

# Cluster management
cluster-status     # Check all nodes status
status            # Same as cluster-status (alias)
deploy-all        # Deploy to all worker nodes

• Slade Master: 192.168.56.10 + Real IP (DHCP)
• Worker 1: 192.168.56.11 + Real IP (DHCP)
• Worker 2: 192.168.56.12 + Real IP (DHCP)
• Worker 3: 192.168.56.13 + Real IP (DHCP)
• Worker 4: 192.168.56.14 + Real IP (DHCP)

• Public Network: Bridged for real internet IP
• Private Network: Internal cluster communication

• Colorful ASCII art with figlet and lolcat
• System information display with neofetch
• Role-specific welcome messages
• Interactive command suggestions

• Color-coded prompts for each node
• Custom aliases and shortcuts
• Enhanced bash experience
• Command history and completion

• SSH key-based authentication
• Cluster status monitoring
• Centralized deployment scripts
• Desktop GUI for visual management

# Start specific VMs
vagrant up slade          # Start master only
vagrant up worker1        # Start worker 1 only
vagrant up worker2 worker3 # Start workers 2 & 3

# Connect to specific VMs
vagrant ssh slade         # Connect to master
vagrant ssh worker1       # Connect to worker 1

# Halt specific VMs
vagrant halt worker1      # Stop worker 1
vagrant halt slade        # Stop master

# Status check
vagrant status            # Show all VM status

1. Check VirtualBox Host-Only Network settings
2. Ensure bridged adapter is selected correctly
3. Try different network interface in bridge settings

# From Slade master, regenerate SSH keys
ssh-keygen -t rsa -b 4096 -f ~/.ssh/id_rsa -N ""

# Copy keys to workers (replace X with worker number)
ssh-copy-id vagrant@192.168.56.1X

• Start VMs one by one instead of all together
• Reduce worker memory if needed (edit Vagrantfile)
• Use vagrant halt when not using specific nodes

# Graceful shutdown
vagrant halt

# Complete removal (frees disk space)
vagrant destroy

# Remove specific VMs
vagrant destroy slade worker1

• SSH key-based authentication between nodes
• Isolated private network for cluster communication
• Real IP access for internet connectivity
• User-based access control
