🚀 Quick Start

Installation

# Install SpindleX
pip install spindlex

# With async support
pip install spindlex[async]

# With all features
pip install spindlex[dev,gssapi]

30-Second Example

from spindlex import SSHClient

# 🔌 Connect and authenticate
with SSHClient() as client:
    client.connect('your-server.com', username='user', password='pass')
    
    # 💻 Execute commands
    stdin, stdout, stderr = client.exec_command('ls -la')
    print(stdout.read().decode())
    
    # 📁 Transfer files via SFTP
    with client.open_sftp() as sftp:
        sftp.get('/remote/file.txt', '/local/file.txt')
        sftp.put('/local/data.json', '/remote/backup.json')

---

🛠️ Examples

🔑 Key-Based Authentication

from spindlex import SSHClient
from spindlex.crypto.pkey import Ed25519Key

# Load your private key
private_key = Ed25519Key.from_private_key_file('~/.ssh/id_ed25519')

with SSHClient() as client:
    client.connect(
        hostname='production-server.com',
        username='deploy',
        pkey=private_key
    )
    
    # Deploy your application
    client.exec_command('docker-compose up -d')

⚡ Async Operations

import asyncio
from spindlex import AsyncSSHClient

async def deploy_to_multiple_servers():
    servers = ['web1.example.com', 'web2.example.com', 'web3.example.com']
    
    async def deploy_to_server(hostname):
        async with AsyncSSHClient() as client:
            await client.connect(hostname, username='deploy', key_filename='~/.ssh/deploy_key')
            
            # Parallel deployment
            await client.exec_command('git pull origin main')
            await client.exec_command('docker-compose restart')
            
            print(f"✅ Deployed to {hostname}")
    
    # Deploy to all servers concurrently
    await asyncio.gather(*[deploy_to_server(server) for server in servers])

# Run the deployment
asyncio.run(deploy_to_multiple_servers())

🌐 Port Forwarding

from spindlex import SSHClient

with SSHClient() as client:
    client.connect('bastion.example.com', username='user', key_filename='~/.ssh/id_rsa')
    
    # Forward local port 5432 to remote database
    tunnel_id = client.create_local_port_forward(
        local_port=5432,
        remote_host='db.internal.com',
        remote_port=5432
    )
    
    # Now connect to localhost:5432 to reach the database
    print("🔗 Tunnel established! Connect to localhost:5432")
    
    # Keep tunnel open
    input("Press Enter to close tunnel...")
    client.close_port_forward(tunnel_id)

📁 Advanced SFTP Operations

from spindlex import SSHClient
import os

with SSHClient() as client:
    client.connect('fileserver.com', username='admin', password='secure_pass')
    
    with client.open_sftp() as sftp:
        # 📊 Get file stats
        file_stats = sftp.stat('/remote/important.log')
        print(f"File size: {file_stats.size} bytes")
        
        # 📂 List directory contents
        files = sftp.listdir('/var/log')
        for file in files:
            print(f"📄 {file}")
        
        # 🔄 Sync directories
        for root, dirs, files in os.walk('/local/backup'):
            for file in files:
                local_path = os.path.join(root, file)
                remote_path = f"/remote/backup/{file}"
                sftp.put(local_path, remote_path)
                print(f"📤 Uploaded {file}")
