gmab 0.1.4

Give Me A Box - CLI tool to spawn, list, and manage temporary cloud boxes

GMAB (Give Me A Box) v0.1.4

A CLI tool to spawn, list, and manage temporary cloud boxes.

Why?

• Need a quick VPS for pentesting, bug bounty, or scanning?
• Want to run commands from a different IP without using your local machine?
• No need for manual cloud console interaction - just gmab spawn, and you're in!

Features

• Spawn temporary cloud instances that automatically expire
• List active instances across providers
• Terminate instances individually or in bulk
• Support for multiple cloud providers (Linode, AWS, Hetzner)
• Provider-agnostic command interface
• SSH key management

Installation

Using pip

The easiest way to install GMAB is directly from PyPI:

pip install gmab

From Source

You can also install directly from the source code:

# Clone the repository
git clone https://github.com/superfishlu/gmab.git
cd gmab

# Install the package
pip install .

# For development (editable mode)
pip install -e .

Configuration

Before you can use GMAB, you need to configure it with your provider credentials and preferences. You must run the configure command before using any other functionality.

Interactive Configuration

Use the configure command to set up or modify your configuration:

# Configure all settings and providers
gmab configure

# Configure a specific provider
gmab configure -p linode

Note: GMAB will only use providers that you've explicitly configured. If you don't configure a provider, GMAB will not attempt to use it, preventing any unnecessary API calls or errors.

Viewing Configuration

You can view your current configuration using the --print flag:

gmab configure --print

This will display:

• The location of your config files
• The contents of your configuration (with sensitive data masked)
• The current settings for all configured providers

Usage

Spawn a new instance

# Using default provider
gmab spawn

# Specify a provider
gmab spawn --provider linode
gmab spawn --provider aws
gmab spawn --provider hetzner

# Override defaults
gmab spawn -p linode -r us-east -i linode/ubuntu22.04 -t 120

List instances

# List all instances
gmab list

# List instances for specific provider
gmab list --provider linode

Terminate instances

# Terminate by ID or label
gmab terminate instance-123
gmab terminate my-instance-label

# Terminate multiple instances
gmab terminate instance-1 instance-2

# Terminate all instances
gmab terminate all

# Terminate expired instances
gmab terminate expired

Version Information

You can check the installed version of GMAB using the -v or --version flag:

# Check version with short flag
gmab -v
# gmab 0.1.1

# Check version with long flag
gmab --version
# gmab 0.1.1

This is useful for debugging and ensuring you have the latest version installed.

Provider-Specific Notes

Linode

• Requires API key with full access
• Default instance type: Nanode 1GB
• Supports all regions

AWS

• Requires access key and secret key
• Default instance type: t2.micro
• Creates VPC and security group if needed
• Supports all regions

Hetzner

• Requires API token
• Default instance type: CPX11
• Supports all Hetzner Cloud regions
• Uses label-based instance tracking

Best Practices

1. SSH Key: Use an ed25519 key pair for better security

ssh-keygen -t ed25519 -C "[e-mail]"

2. Instance Lifetime: Set reasonable expiration times and automatic cleanup

# Set lifetime when spawning
gmab spawn -t 60  # 60 minutes lifetime

# Set up automatic cleanup with cron (Linux/Mac)
# Run every hour to clean up expired instances
0 * * * * gmab terminate expired -y

# For Windows, use Task Scheduler to run:
# gmab.exe terminate expired -y

3. Regular Cleanup: Periodically check and terminate expired instances

gmab terminate expired

4. Provider Organization:

• AWS: Create a dedicated IAM user for GMAB
• Linode: Use a dedicated API key
• Hetzner: Create a dedicated project named "gmab" and generate the API token specifically for this project

5. Security:

• Store configuration files securely
• Don't commit provider credentials to version control
• Regularly rotate API keys and tokens

Configuration Storage

GMAB follows platform-specific standards for storing configuration:

• Linux/macOS: ~/.config/gmab/ or $XDG_CONFIG_HOME/gmab/
• Windows: %APPDATA%\gmab\
• Override: Set GMAB_CONFIG_DIR environment variable

Two main configuration files are used:

1. config.json - General settings (SSH key, default lifetime, default provider)
2. providers.json - Provider-specific credentials and defaults

AWS Resources Created

When using AWS as a provider, GMAB automatically creates and manages the following resources:

1. VPC (Virtual Private Cloud)

   • Named: 'gmab-vpc'
   • CIDR: 10.0.0.0/16
   • DNS hostnames enabled

2. Internet Gateway

   • Named: 'gmab-igw'
   • Attached to gmab-vpc

3. Subnet

   • Named: 'gmab-subnet'
   • CIDR: 10.0.1.0/24
   • Auto-assign public IP enabled

4. Route Table

   • Named: 'gmab-rt'
   • Routes all traffic (0.0.0.0/0) through the internet gateway
   • Associated with gmab-subnet

5. Security Group

   • Named: 'gmab-sg'
   • Inbound rules: SSH (port 22) from anywhere
   • All resources are tagged with 'gmab=true'

Provider Recommendations

While GMAB supports multiple cloud providers, it has been primarily developed and tested with Linode in mind. Linode typically offers:

• Faster instance provisioning times
• Simpler setup (no VPC/networking configuration needed)
• More straightforward API and authentication
• Lower costs for basic instances
• Consistent image names across regions (e.g., "linode/ubuntu22.04" works everywhere)

Hetzner Cloud provides similar ease of use and speed to Linode, with:

• Simple API and quick instance provisioning
• Consistent image names across regions
• Automatic network configuration
• Competitive pricing

AWS on the other hand adds some complexity due to:

• Network setup (VPC, subnet, security groups) required per region
• AMI IDs (image IDs) are different between regions
• Instance types may not be available in all regions
• Slower API responses and instance provisioning
• More complex authentication setup

For these reasons, when using GMAB with AWS we recommend:

• Stick to one region for all your instances
• Make sure your chosen AMI ID exists in your region
• Use modern instance types (t3.micro instead of t2.micro) for better region compatibility
• Configure your AWS credentials properly with sufficient permissions for VPC/networking
• Be patient as instance creation takes longer than other providers

If you're just getting started with GMAB, we recommend beginning with Linode or Hetzner for the simplest experience.

Example configuration session:

$ gmab configure
Using config directory: /home/user/.config/gmab

Access Key: your-access-key
Secret Key: your-secret-key
Default region [eu-west-1]:
