'Strict-Transport-Security': 'max-age=31536000; includeSubDomains; preload'
|
||||
});
|
||||
})();
|
||||
```
|
||||
|
||||
### Port Proxying
|
||||
|
||||
You can also set up a port proxy to forward traffic from one port to another, which is useful for dynamic port forwarding scenarios.
|
||||
|
||||
```typescript
|
||||
import { PortProxy } from '@push.rocks/smartproxy';
|
||||
|
||||
// Create a PortProxy to forward traffic from port 5000 to port 3000
|
||||
const myPortProxy = new PortProxy(5000, 3000);
|
||||
|
||||
// Start the port proxy
|
||||
await myPortProxy.start();
|
||||
|
||||
// To stop the port proxy, simply call
|
||||
await myPortProxy.stop();
|
||||
```
|
||||
|
||||
### Enabling SSL Redirection
|
||||
|
||||
Easily redirect HTTP traffic to HTTPS using the `SslRedirect` class. This is particularly useful when ensuring all traffic uses encryption.
|
||||
### HTTP to HTTPS Redirection
|
||||
|
||||
```typescript
|
||||
import { SslRedirect } from '@push.rocks/smartproxy';
|
||||
|
||||
// Instantiate the SslRedirect on port 80 (HTTP)
|
||||
const mySslRedirect = new SslRedirect(80);
|
||||
|
||||
// Start listening and redirecting to HTTPS
|
||||
await mySslRedirect.start();
|
||||
|
||||
// To stop the redirection, use
|
||||
await mySslRedirect.stop();
|
||||
// Create and start HTTP to HTTPS redirect service on port 80
|
||||
const redirector = new SslRedirect(80);
|
||||
redirector.start();
|
||||
```
|
||||
|
||||
### Advanced Usage
|
||||
### TCP Port Forwarding with Domain-based Routing
|
||||
|
||||
The package integrates seamlessly with TypeScript, allowing for advanced use cases, such as implementing custom routing logic, authentication mechanisms, and handling WebSocket connections through the network proxy.
|
||||
```typescript
|
||||
import { PortProxy } from '@push.rocks/smartproxy';
|
||||
|
||||
For a more advanced setup involving WebSocket proxying and dynamic configuration reloading, refer to the network proxy example provided above. The WebSocket support demonstrates how seamless it is to work with real-time applications.
|
||||
// Configure port proxy with domain-based routing
|
||||
const portProxy = new PortProxy({
|
||||
fromPort: 443,
|
||||
toPort: 8443,
|
||||
targetIP: 'localhost', // Default target host
|
||||
sniEnabled: true, // Enable SNI inspection
|
||||
|
||||
Remember, when dealing with certificates and private keys for HTTPS configurations, always secure your keys and store them appropriately.
|
||||
// Enhanced reliability settings
|
||||
initialDataTimeout: 60000, // 60 seconds for initial TLS handshake
|
||||
socketTimeout: 3600000, // 1 hour socket timeout
|
||||
maxConnectionLifetime: 3600000, // 1 hour connection lifetime
|
||||
inactivityTimeout: 3600000, // 1 hour inactivity timeout
|
||||
maxPendingDataSize: 10 * 1024 * 1024, // 10MB buffer for large TLS handshakes
|
||||
|
||||
`@push.rocks/smartproxy` provides a solid foundation for handling high workloads and complex proxying requirements with ease, whether you're implementing SSL redirections, port forwarding, or extensive routing and WebSocket support in your network.

|
||||
|
||||
```typescript
|
||||
import { IPTablesProxy } from '@push.rocks/smartproxy';
|
||||
|
||||
// Configure IPTables to forward from port 80 to 8080
|
||||
const iptables = new IPTablesProxy({
|
||||
fromPort: 80,
|
||||
toPort: 8080,
|
||||
toHost: 'localhost',
|
||||
preserveSourceIP: true,
|
||||
deleteOnExit: true // Automatically clean up rules on process exit
|
||||
});
|
||||
|
||||
iptables.start();
|
||||
```
|
||||
|
||||

||||
|
||||
```typescript
|
||||
import { Port80Handler } from '@push.rocks/smartproxy';
|
||||
|
||||
// Create an ACME handler for Let's Encrypt
|
||||
const acmeHandler = new Port80Handler();
|
||||
|
||||
// Add domains to manage certificates for
|
||||
acmeHandler.addDomain('example.com');
|
||||
acmeHandler.addDomain('api.example.com');
|
||||
```

## Advanced Features
|
||||
|
||||
### TLS Handshake Optimization
|
||||
|
||||
The enhanced `PortProxy` implementation includes significant improvements for TLS handshake handling:
|
||||
|
||||
- Robust SNI extraction with improved error handling
|
||||
- Increased buffer size for complex TLS handshakes (10MB)
|
||||
- Longer initial handshake timeout (60 seconds)
|
||||
- Detection and tracking of TLS connection states
|
||||
- Optional detailed TLS debug logging for troubleshooting
|
||||
- Browser compatibility fixes for Chrome certificate errors
|
||||
|
||||
```typescript
|
||||
// Example configuration to solve Chrome certificate errors
|
||||
const portProxy = new PortProxy({
|
||||
// ... other settings
|
||||
initialDataTimeout: 60000, // Give browser more time for handshake
|
||||
maxPendingDataSize: 10 * 1024 * 1024, // Larger buffer for complex handshakes
|
||||
enableTlsDebugLogging: true, // Enable when troubleshooting
|
||||
});
|
||||
```
|
||||
|
||||
### Connection Management and Monitoring
|
||||
|
||||
The `PortProxy` class includes built-in connection tracking and monitoring:
|
||||
|
||||
- Automatic cleanup of idle connections with configurable timeouts
|
||||
- Timeouts for connections that exceed maximum lifetime
|
||||
- Detailed logging of connection states
|
||||
- Termination statistics
|
||||
- Randomized timeouts to prevent "thundering herd" problems
|
||||
- Per-domain timeout configuration
|
||||
|
||||
### WebSocket Support
|
||||
|
||||
The `NetworkProxy` class provides WebSocket support with:
|
||||
|
||||
- WebSocket connection proxying
|
||||
- Automatic heartbeat monitoring
|
||||
- Connection cleanup for inactive WebSockets
|
||||
|
||||
### SNI-based Routing
|
||||
|
||||
The `PortProxy` class can inspect the SNI (Server Name Indication) field in TLS handshakes to route connections based on the requested domain:
|
||||
|
||||
- Multiple backend targets per domain
|
||||
- Round-robin load balancing
|
||||
- Domain-specific allowed IP ranges
|
||||
- Protection against SNI renegotiation attacks
|
||||
|
||||
## Troubleshooting
|
||||
|
||||
### Browser Certificate Errors
|
||||
|
||||
If you experience certificate errors in browsers, especially in Chrome, try these solutions:
|
||||
|
||||
1. **Increase Initial Data Timeout**: Set `initialDataTimeout` to 60 seconds or higher
|
||||
2. **Increase Buffer Size**: Set `maxPendingDataSize` to 10MB or higher
|
||||
3. **Enable TLS Debug Logging**: Set `enableTlsDebugLogging: true` to troubleshoot handshake issues
|
||||
4. **Enable Keep-Alive Probes**: Set `enableKeepAliveProbes: true` for better connection stability
|
||||
5. **Check Certificate Chain**: Ensure your certificate chain is complete and in the correct order
|
||||
|
||||
```typescript
|
||||
// Configuration to fix Chrome certificate errors
|
||||
const portProxy = new PortProxy({
|
||||
// ... other settings
|
||||
initialDataTimeout: 60000,
|
||||
maxPendingDataSize: 10 * 1024 * 1024,
|
||||
enableTlsDebugLogging: true,
|
||||
enableKeepAliveProbes: true
|
||||
});
|
||||
```
|
||||
|
||||
### Connection Stability
|
||||
|
||||
For improved connection stability in high-traffic environments:
|
||||
|
||||
1. **Set Appropriate Timeouts**: Use longer timeouts for long-lived connections
|
||||
2. **Use Domain-Specific Timeouts**: Configure per-domain timeouts for different types of services
|
||||
3. **Enable TCP Keep-Alive**: Ensure `keepAlive` is set to `true`
|
||||
4. **Monitor Connection Statistics**: Enable detailed logging to track termination reasons
|
||||
5. **Fine-tune Inactivity Checks**: Adjust `inactivityCheckInterval` based on your traffic patterns
