 # Project Analysis

 ## Architecture Overview
-This is a comprehensive network diagnostics toolkit that provides various network-related utilities. The main entry point is the `SmartNetwork` class which orchestrates all functionality.
+This is a comprehensive network diagnostics toolkit. The main entry point is the `SmartNetwork` class which orchestrates all functionality. System-dependent operations are delegated to a Rust binary via JSON-over-stdin/stdout IPC using `@push.rocks/smartrust`.

 Key features:
- Speed testing via Cloudflare (parallelizable with duration support)
- Ping operations with statistics
- Port availability checks (local and remote)
- Network gateway discovery
- Public IP retrieval
- DNS resolution
- HTTP endpoint health checks
- Traceroute functionality (with fallback stub)
+- Speed testing via Cloudflare (parallelizable with duration support) — pure TS
+- ICMP ping with statistics — Rust binary (surge-ping)
+- Port availability checks (local and remote) — Rust binary (tokio TCP / socket2)
+- Network gateway discovery — Rust binary (parses /proc/net/route on Linux)
+- Public IP retrieval — pure TS
+- DNS resolution via smartdns — pure TS
+- HTTP endpoint health checks — pure TS
+- Traceroute — Rust binary (raw ICMP sockets via socket2)
+
+## Rust Binary Architecture (v4.5.0+)
+
+### Binary: `rustnetwork`
+- Located in `rust/crates/rustnetwork/`
+- Cross-compiled for linux_amd64 and linux_arm64 via `@git.zone/tsrust`
+- Output: `dist_rust/rustnetwork_linux_amd64`, `dist_rust/rustnetwork_linux_arm64`
+- IPC mode: `--management` flag for JSON-over-stdin/stdout
+
+### IPC Commands
+| Method | Description |
+|--------|-------------|
+| `healthPing` | Liveness check (returns `{ pong: true }`) |
+| `ping` | ICMP ping with count/timeout, returns stats |
+| `traceroute` | Hop-by-hop latency via raw ICMP sockets |
+| `tcpPortCheck` | TCP connect probe to remote host:port |
+| `isLocalPortFree` | Bind test on IPv4 + IPv6 |
+| `defaultGateway` | Parse /proc/net/route for default interface |
+
+### TypeScript Bridge
+- `ts/smartnetwork.classes.rustbridge.ts` — Singleton `RustNetworkBridge` wrapping `smartrust.RustBridge`
+- `SmartNetwork` class has `start()`/`stop()` lifecycle for the bridge
+- `ensureBridge()` auto-starts on first use
+
+### Build Pipeline
+- `pnpm build` = `tsbuild tsfolders --allowimplicitany && tsrust`
+- Targets configured in `.smartconfig.json` under `@git.zone/tsrust`

 ## Key Components

 ### SmartNetwork Class
 - Central orchestrator for all network operations
+- Requires `start()` before using ping/traceroute/port/gateway operations
 - Supports caching via `cacheTtl` option for gateway and public IP lookups
 - Plugin architecture for extensibility

+### RustNetworkBridge Class
+- Singleton pattern via `getInstance()`
+- Binary search: dist_rust/ (platform-suffixed) > rust/target/release/ > rust/target/debug/
+- `searchSystemPath: false` — only looks in local paths
+
 ### CloudflareSpeed Class
 - Handles internet speed testing using Cloudflare's infrastructure
 - Supports parallel streams and customizable test duration
- Measures both download and upload speeds using progressive chunk sizes
- Includes latency measurements (jitter, median, average)
+- Upload speed measurement uses server-timing header with client-side timing fallback

 ### Error Handling
 - Custom `NetworkError` and `TimeoutError` classes for better error context
 - Error codes follow Node.js conventions (ENOTSUP, EINVAL, ETIMEOUT)
+- Ping/port methods gracefully degrade on errors (return alive=false / false)

 ### Logging
 - Global logger interface for consistent logging across the codebase
 - Replaceable logger implementation (defaults to console)
- Used primarily for error reporting in speed tests

 ### Statistics Helpers
 - Utility functions for statistical calculations (average, median, quartile, jitter)
- Used extensively by speed testing and ping operations
+- Used by speed testing; ping statistics now computed server-side in Rust

-## Recent Changes (v4.0.0 - v4.0.1)
- Added configurable speed test options (parallelStreams, duration)
- Introduced plugin architecture for runtime extensibility
- Enhanced error handling with custom error classes
- Added global logging interface
- Improved connection management by disabling HTTP connection pooling
- Fixed memory leaks from listener accumulation
- Minor formatting fixes for consistency
+## Dependencies
+- **Runtime**: `@push.rocks/smartrust` (IPC bridge), `@push.rocks/smartdns` (DNS resolution)
+- **Removed in v4.5.0**: `@push.rocks/smartping`, `@push.rocks/smartstring`, `isopen`, `systeminformation`
+- **Dev**: `@git.zone/tsrust` (Rust cross-compilation)

 ## Testing
- Comprehensive test suite covering all major features
- Tests run on both browser and node environments
- Uses @push.rocks/tapbundle for testing with expectAsync
- Performance tests for speed testing functionality
- Edge case handling for network errors and timeouts
+- `test/test.ts` — Core smoke tests (speed, ports, gateways, public IPs)
+- `test/test.ping.ts` — ICMP ping tests (requires CAP_NET_RAW for alive=true)
+- `test/test.ports.ts` — Comprehensive port testing (27 tests)
+- `test/test.features.ts` — DNS, HTTP health check, traceroute, multi-ping, plugins, caching
+- All tests require `start()`/`stop()` lifecycle for the Rust bridge

 ## Technical Details
 - ESM-only package (module type)
 - TypeScript with strict typing
- Depends on external modules for specific functionality:
-  - @push.rocks/smartping for ICMP operations
-  - public-ip for external IP discovery
-  - systeminformation for network interface details
-  - isopen for remote port checking
- Uses native Node.js modules for DNS, HTTP/HTTPS, and network operations
+- Node built-in imports use `node:` prefix throughout
+- Uses native Node.js modules for HTTP/HTTPS and os.networkInterfaces()
+- Rust binary requires no elevated privileges for port checks; ICMP ping needs CAP_NET_RAW or appropriate ping_group_range

 ## Design Patterns
+- Singleton pattern for RustNetworkBridge
 - Factory pattern for plugin registration
 - Caching pattern with TTL for expensive operations
 - Promise-based async/await throughout
- Deferred promises for complex async coordination
 - Error propagation with custom error types
+- Graceful degradation when ICMP permissions unavailable

+- **🔧 Plugin Architecture** - Extend functionality with custom plugins
+- **📝 Full TypeScript Support** - Complete type definitions included

-## Usage
-
-In this section, we will dive deep into the capabilities of the `@push.rocks/smartnetwork` package, exploring its various features through TypeScript examples. The package is designed to simplify network diagnostics tasks, including speed tests, port availability checks, ping operations, and more.
+## 💻 Usage

 ### Basic Setup

-First, import the package into your project:
+First, import and initialize SmartNetwork:

 ```typescript
 import { SmartNetwork } from '@push.rocks/smartnetwork';
+
+// Basic instance
+const network = new SmartNetwork();
+
+// Start the Rust bridge (auto-started on first use, but explicit start is recommended)
+await network.start();
+
+// ... use the network instance ...
+
+// Clean up when done (stops the Rust bridge process)
+await network.stop();
+
+// With caching enabled (60 seconds TTL)
+const cachedNetwork = new SmartNetwork({ cacheTtl: 60000 });
 ```

-Then, create an instance of `SmartNetwork`:
+### 🏎️ Network Speed Testing

-```typescript
-const myNetwork = new SmartNetwork();
-```
-
-### Performing a Speed Test
-
-You can measure the network speed using the `getSpeed` method. It supports optional parameters:
-
- `parallelStreams`: number of concurrent streams (default: 1)
- `duration`: test duration in seconds (default: fixed segments)
+Measure your network performance using Cloudflare's global infrastructure:

 ```typescript
 const speedTest = async () => {
-  // Default fixed-segment test
-  let r = await myNetwork.getSpeed();
-  console.log(`Download: ${r.downloadSpeed} Mbps, Upload: ${r.uploadSpeed} Mbps`);
+  // Quick speed test
+  const result = await network.getSpeed();
+  console.log(`Download: ${result.downloadSpeed} Mbps`);
+  console.log(`Upload: ${result.uploadSpeed} Mbps`);

-  // Parallel + duration-based test
-  r = await myNetwork.getSpeed({ parallelStreams: 3, duration: 5 });
-  console.log(`Download: ${r.downloadSpeed} Mbps, Upload: ${r.uploadSpeed} Mbps`);
+  // Advanced configuration
+  const advancedResult = await network.getSpeed({ 
+    parallelStreams: 3,  // Number of concurrent connections
+    duration: 5          // Test duration in seconds
+  });
+  console.log(`Download: ${advancedResult.downloadSpeed} Mbps`);
+  console.log(`Upload: ${advancedResult.uploadSpeed} Mbps`);
 };
-
-speedTest();
 ```

-### Checking Port Availability Locally
+### 🔌 Port Management

-The `isLocalPortUnused` method allows you to check if a specific port on your local machine is available for use.
+#### Check Local Port Availability
+
+Verify if a port is available on your local machine (checks both IPv4 and IPv6):

 ```typescript
 const checkLocalPort = async (port: number) => {
-  const isUnused = await myNetwork.isLocalPortUnused(port);
+  const isUnused = await network.isLocalPortUnused(port);
  if (isUnused) {
-    console.log(`Port ${port} is available.`);
+    console.log(`✅ Port ${port} is available`);
  } else {
-    console.log(`Port ${port} is in use.`);
+    console.log(`❌ Port ${port} is in use`);
  }
 };

-checkLocalPort(8080); // Example port number
+await checkLocalPort(8080);
 ```

-### Checking Remote Port Availability
+#### Find Free Port in Range

-To verify if a port is available on a remote server, use `isRemotePortAvailable`. You can specify target as `"host:port"` or host plus a numeric port.
+Automatically discover available ports:

 ```typescript
-// Using "host:port"
-await myNetwork.isRemotePortAvailable('example.com:443');
+const findFreePort = async () => {
+  // Find a free port between 3000 and 3100 (sequential - returns first available)
+  const freePort = await network.findFreePort(3000, 3100);
  
-// Using host + port
-await myNetwork.isRemotePortAvailable('example.com', 443);
+  if (freePort) {
+    console.log(`🎉 Found free port: ${freePort}`);
+  } else {
+    console.log('😢 No free ports available in range');
+  }
  
-// UDP is not supported:
+  // Find a random free port in range (useful to avoid port conflicts)
+  const randomPort = await network.findFreePort(3000, 3100, { randomize: true });
+  console.log(`🎲 Random free port: ${randomPort}`);
+  
+  // Exclude specific ports from the search
+  const portWithExclusions = await network.findFreePort(3000, 3100, {
+    exclude: [3000, 3001, 3005]  // Skip these ports even if they're free
+  });
+  console.log(`🚫 Free port (excluding specific ports): ${portWithExclusions}`);
+  
+  // Combine randomize with exclude options
+  const randomWithExclusions = await network.findFreePort(3000, 3100, {
+    randomize: true,
+    exclude: [3000, 3001, 3005]
+  });
+  console.log(`🎲🚫 Random free port (with exclusions): ${randomWithExclusions}`);
+};
+```
+
+#### Check Remote Port Availability
+
+Test if services are accessible on remote servers:
+
+```typescript
+// Method 1: Using "host:port" syntax
+const isOpen1 = await network.isRemotePortAvailable('example.com:443');
+
+// Method 2: Using separate host and port
+const isOpen2 = await network.isRemotePortAvailable('example.com', 443);
+
+// Method 3: With advanced options
+const isOpen3 = await network.isRemotePortAvailable('example.com', {
+  port: 443,
+  protocol: 'tcp',     // Only TCP is supported
+  retries: 3,          // Number of connection attempts
+  timeout: 5000        // Timeout per attempt in ms
+});
+
+// Note: UDP is not supported
 try {
-  await myNetwork.isRemotePortAvailable('example.com', { port: 53, protocol: 'udp' });
+  await network.isRemotePortAvailable('example.com', { 
+    port: 53, 
+    protocol: 'udp' 
+  });
 } catch (e) {
-  console.error((e as any).code); // ENOTSUP
+  console.error('UDP not supported:', e.code); // ENOTSUP
 }
 ```

-### Using Ping
+### 📡 Network Connectivity

-The `ping` method sends ICMP echo requests and optionally repeats them to collect statistics.
+#### Ping Operations
+
+Test connectivity and measure latency:

 ```typescript
-// Single ping
-const p1 = await myNetwork.ping('google.com');
-console.log(`Alive: ${p1.alive}, RTT: ${p1.time} ms`);
+// Simple ping
+const pingResult = await network.ping('google.com');
+console.log(`Host alive: ${pingResult.alive}`);
+console.log(`RTT: ${pingResult.time} ms`);

-// Multiple pings with statistics
-const stats = await myNetwork.ping('google.com', { count: 5 });
-console.log(
-  `min=${stats.min} ms, max=${stats.max} ms, avg=${stats.avg.toFixed(2)} ms, loss=${stats.packetLoss}%`,
-);
+// Detailed ping statistics
+const pingStats = await network.ping('google.com', { 
+  count: 5,          // Number of pings
+  timeout: 1000      // Timeout per ping in ms
+});
+
+console.log(`📊 Ping Statistics:`);
+console.log(`  Packet loss: ${pingStats.packetLoss}%`);
+console.log(`  Min: ${pingStats.min} ms`);
+console.log(`  Max: ${pingStats.max} ms`);
+console.log(`  Avg: ${pingStats.avg.toFixed(2)} ms`);
+console.log(`  Stddev: ${pingStats.stddev.toFixed(2)} ms`);
 ```

-### Getting Network Gateways
+#### Traceroute

-You can also retrieve network interfaces (gateways) and determine the default gateway. Caching with TTL is supported via constructor options.
+Analyze network paths hop-by-hop:

 ```typescript
-// Create with cache TTL of 60 seconds
-const netCached = new SmartNetwork({ cacheTtl: 60000 });
+const hops = await network.traceroute('google.com', { 
+  maxHops: 10,      // Maximum number of hops
+  timeout: 5000     // Timeout in ms
+});

-// List all interfaces
-const gateways = await netCached.getGateways();
-console.log(gateways);
-
-// Get default gateway
-const defaultGw = await netCached.getDefaultGateway();
-console.log(defaultGw);
+console.log('🛤️ Route to destination:');
+hops.forEach(hop => {
+  const rtt = hop.rtt === null ? '*' : `${hop.rtt} ms`;
+  console.log(`  ${hop.ttl}\t${hop.ip}\t${rtt}`);
+});
 ```

-### Discovering Public IP Addresses
+*Note: Falls back to a single-hop stub if the `traceroute` binary is unavailable.*

-To find out your public IPv4 and IPv6 addresses (with caching):
+### 🌍 DNS Operations
+
+Resolve various DNS record types using @push.rocks/smartdns with intelligent resolution strategy:

 ```typescript
-const publicIps = await netCached.getPublicIps();
-console.log(`Public IPv4: ${publicIps.v4}`);
-console.log(`Public IPv6: ${publicIps.v6}`);
+const dnsRecords = await network.resolveDns('example.com');
+
+console.log('🔍 DNS Records:');
+console.log('  A records:', dnsRecords.A);        // IPv4 addresses
+console.log('  AAAA records:', dnsRecords.AAAA);  // IPv6 addresses
+
+// MX records include priority
+dnsRecords.MX.forEach(mx => {
+  console.log(`  📧 Mail server: ${mx.exchange} (priority: ${mx.priority})`);
+});
+
+// Properly handles local hostnames (localhost, etc.)
+const localDns = await network.resolveDns('localhost');
+console.log('  Localhost:', localDns.A);  // Returns ['127.0.0.1']
 ```

-The `@push.rocks/smartnetwork` package provides an easy-to-use, comprehensive suite of tools for network diagnostics and monitoring, encapsulating complex network operations into simple asynchronous methods. By leveraging TypeScript, developers can benefit from type checking, ensuring that they can work with clear structures and expectations.
+*DNS resolution uses a `prefer-system` strategy: tries system resolver first (respects /etc/hosts and local DNS), with automatic fallback to Cloudflare DoH for external domains.*

-These examples offer a glimpse into the module's utility in real-world scenarios, demonstrating its versatility in handling common network tasks. Whether you're developing a network-sensitive application, diagnosing connectivity issues, or simply curious about your network performance, `@push.rocks/smartnetwork` equips you with the tools you need.
+### 🏥 HTTP/HTTPS Health Checks

-### Plugin Architecture
-
-You can extend `SmartNetwork` with custom plugins by registering them at runtime:
+Monitor endpoint availability and response times:

 ```typescript
-import { SmartNetwork } from '@push.rocks/smartnetwork';
+const health = await network.checkEndpoint('https://api.example.com/health', {
+  timeout: 5000  // Request timeout in ms
+});

-// Define your plugin class or constructor
-class MyCustomPlugin {
-  // plugin implementation goes here
+console.log(`🩺 Endpoint Health:`);
+console.log(`  Status: ${health.status}`);
+console.log(`  RTT: ${health.rtt} ms`);
+console.log(`  Headers:`, health.headers);
+```
+
+### 🖥️ Network Interface Information
+
+#### Get All Network Interfaces
+
+List all network adapters on the system:
+
+```typescript
+const gateways = await network.getGateways();
+
+Object.entries(gateways).forEach(([name, interfaces]) => {
+  console.log(`🔌 Interface: ${name}`);
+  interfaces.forEach(iface => {
+    console.log(`  ${iface.family}: ${iface.address}`);
+    console.log(`  Netmask: ${iface.netmask}`);
+    console.log(`  MAC: ${iface.mac}`);
+  });
+});
+```
+
+#### Get Default Gateway
+
+Retrieve the primary network interface:
+
+```typescript
+const defaultGateway = await network.getDefaultGateway();
+
+if (defaultGateway) {
+  console.log('🌐 Default Gateway:');
+  console.log('  IPv4:', defaultGateway.ipv4.address);
+  console.log('  IPv6:', defaultGateway.ipv6.address);
+}
+```
+
+### 🌎 Public IP Discovery
+
+Discover your public-facing IP addresses:
+
+```typescript
+const publicIps = await network.getPublicIps();
+
+console.log(`🌍 Public IPs:`);
+console.log(`  IPv4: ${publicIps.v4 || 'Not available'}`);
+console.log(`  IPv6: ${publicIps.v6 || 'Not available'}`);
+```
+
+### ⚡ Performance Caching
+
+Reduce network calls with built-in caching:
+
+```typescript
+// Create instance with 60-second cache TTL
+const cachedNetwork = new SmartNetwork({ cacheTtl: 60000 });
+
+// First call fetches from network
+const gateways1 = await cachedNetwork.getGateways();
+const publicIps1 = await cachedNetwork.getPublicIps();
+
+// Subsequent calls within 60 seconds use cache
+const gateways2 = await cachedNetwork.getGateways();    // From cache ⚡
+const publicIps2 = await cachedNetwork.getPublicIps();  // From cache ⚡
+```
+
+### 🔧 Plugin Architecture
+
+Extend SmartNetwork with custom functionality:
+
+```typescript
+// Define your plugin
+class CustomNetworkPlugin {
+  constructor(private smartNetwork: SmartNetwork) {}
+  
+  async customMethod() {
+    // Your custom network logic here
+    return 'Custom result';
+  }
 }

-// Register and unregister your plugin by name
-SmartNetwork.registerPlugin('myPlugin', MyCustomPlugin);
-// Later, remove it if no longer needed
-SmartNetwork.unregisterPlugin('myPlugin');
+// Register the plugin
+SmartNetwork.registerPlugin('customPlugin', CustomNetworkPlugin);
+
+// Use the plugin
+const network = new SmartNetwork();
+const PluginClass = SmartNetwork.pluginsRegistry.get('customPlugin');
+const plugin = new PluginClass(network);
+await plugin.customMethod();
+
+// Clean up when done
+SmartNetwork.unregisterPlugin('customPlugin');
 ```

-Plugins enable you to dynamically augment the core functionality without altering the library's source.
+### 🚨 Error Handling
+
+Handle network errors gracefully with custom error types:
+
+```typescript
+import { NetworkError } from '@push.rocks/smartnetwork';
+
+try {
+  await network.isRemotePortAvailable('example.com', { protocol: 'udp' });
+} catch (error) {
+  if (error instanceof NetworkError) {
+    console.error(`❌ Network error: ${error.message}`);
+    console.error(`   Error code: ${error.code}`);
+  }
+}
+```
+
+### 📚 TypeScript Support
+
+This package is written in TypeScript and provides comprehensive type definitions:
+
+```typescript
+interface SmartNetworkOptions {
+  cacheTtl?: number;  // Cache TTL in milliseconds
+}
+
+interface IFindFreePortOptions {
+  randomize?: boolean;  // If true, returns a random free port instead of the first one
+  exclude?: number[];   // Array of port numbers to exclude from the search
+}
+
+interface Hop {
+  ttl: number;        // Time to live
+  ip: string;         // IP address of the hop
+  rtt: number | null; // Round trip time in ms
+}
+
+// ... and many more types for complete type safety
+```
+
+## 🛠️ Advanced Examples
+
+### Building a Network Monitor
+
+```typescript
+const monitorNetwork = async () => {
+  const network = new SmartNetwork({ cacheTtl: 30000 });
+  
+  // Check critical services
+  const services = [
+    { name: 'Web Server', host: 'example.com', port: 443 },
+    { name: 'Database', host: 'db.internal', port: 5432 },
+    { name: 'Cache', host: 'redis.internal', port: 6379 }
+  ];
+  
+  for (const service of services) {
+    const isUp = await network.isRemotePortAvailable(service.host, service.port);
+    console.log(`${service.name}: ${isUp ? '✅ UP' : '❌ DOWN'}`);
+  }
+  
+  // Check internet connectivity
+  const ping = await network.ping('8.8.8.8');
+  console.log(`Internet: ${ping.alive ? '✅ Connected' : '❌ Disconnected'}`);
+  
+  // Measure network performance
+  const speed = await network.getSpeed();
+  console.log(`Speed: ⬇️ ${speed.downloadSpeed} Mbps / ⬆️ ${speed.uploadSpeed} Mbps`);
+};
+
+// Run monitor every minute
+setInterval(monitorNetwork, 60000);
+```
+
+### Service Discovery
+
+```typescript
+const discoverServices = async () => {
+  const network = new SmartNetwork();
+  const commonPorts = [22, 80, 443, 3000, 3306, 5432, 6379, 8080, 9200];
+  
+  console.log('🔍 Scanning local services...');
+  
+  for (const port of commonPorts) {
+    const isUsed = !(await network.isLocalPortUnused(port));
+    if (isUsed) {
+      console.log(`  Port ${port}: In use (possible service running)`);
+    }
+  }
+};
+```
