x-nets: Скилл для анализа сетевых подключений

--- name: x-nets description: | Enhanced netstat module with cached data and structured output. View network connections, routing tables, and interface statistics in interactive or TSV/CSV formats. **Dependency**: This is an x-cmd module. Install x-cmd first (see x-cmd skill for installation options). see x-cmd skill for installation. license: Apache-2.0 compatibility: POSIX Shell metadata: author: Li Junhao version: "1.0.0" category: x-cmd-extension tags: [x-cmd, network, netstat, connections, monitoring] --- # x nets - Enhanced Network Statistics > Enhanced `netstat` with data caching and structured output formats. --- ## Quick Start ```bash # Update/collect network data (creates cache) x nets update # List available tables x nets ls # View a specific table x nets view internet ``` --- ## Features - **Data Caching**: Update and cache network data for faster access - **Table View**: View different network tables (internet, route, etc.) - **Multiple Formats**: TSV, CSV output for data processing - **Interactive Mode**: Interactive table selection - **Cross-platform**: Works on Linux, macOS, Windows --- ## Commands | Command | Description | |---------|-------------| | `x nets update` | **Collect and cache network data** | | `x nets ls` | List all available tables | | `x nets view <table>` | View table in interactive mode | | `x nets view --tsv <table>` | View table in TSV format | | `x nets view --csv <table>` | View table in CSV format | --- ## Examples ### Update Data (Create Cache) ```bash # Collect and cache all network data x nets update # This creates cached data in ~/.x-cmd.root/data/nets/ ``` ### List Available Tables ```bash # Show all available tables x nets ls # Common tables: # - internet : TCP/UDP connections # - route : Routing table # - interface : Network interface statistics ``` ### View Tables ```bash # Interactive mode - select table to view x nets view # View specific table (interactive) x nets view internet # View in TSV format (for scripting) x nets view --tsv internet # View in CSV format x nets view --csv route ``` ### Data Processing ```bash # Filter connections with awk x nets view --tsv internet | awk -F't' '$1 == "TCP"' # Count connections by state x nets view --tsv internet | cut -f4 | sort | uniq -c # Import into spreadsheet x nets view --csv route > route.csv ``` --- ## Available Tables | Table | Description | |-------|-------------| | `internet` | TCP/UDP connections (like netstat) | | `route` | Routing table information | | `interface` | Network interface statistics | --- ## Table Output Fields ### internet table | Field | Description | |-------|-------------| | Protocol | TCP/UDP | | Local Address | Local IP:port | | Foreign Address | Remote IP:port | | State | Connection state (ESTABLISHED, LISTEN, etc.) | ### route table | Field | Description | |-------|-------------| | Destination | Target network | | Gateway | Next hop | | Flags | Route flags | | Interface | Network interface | --- ## Workflow ```bash # 1. Update data (do this first or when data is stale) x nets update # 2. List available tables x nets ls # 3. View specific table x nets view internet # 4. Or process with other tools x nets view --tsv internet | x csv sql "SELECT * WHERE State = 'ESTABLISHED'" ``` --- ## Platform Notes - **Linux**: Uses `netstat`, `ss`, or `/proc/net` data - **macOS**: Uses `netstat` and `route` commands - **Windows**: Uses `netstat` command Data is cached in `~/.x-cmd.root/data/nets/latest/` for faster access. --- ## Related - Native `netstat(8)` manual page
