x-cmd Network Administration Tools
Overview
This skill provides professional network administration and diagnostic capabilities through the x-cmd ecosystem. The tools enable network administrators, security professionals, and system administrators to perform comprehensive network analysis, troubleshoot connectivity issues, and monitor network infrastructure directly from the terminal.
Available Tools
Network Scanning (nmap)
Comprehensive network discovery and security scanning.
Usage: x nmap [options] [targets]
Key capabilities:
Host discovery and port scanning
Service and version detection
OS fingerprinting
Scriptable vulnerability scanning
Network mapping and topology discovery
Examples:
x nmap -v -A scanme.nmap.org - Comprehensive scan with OS detection
x nmap -v -sn 192.168.0.0/16 - Host discovery only
x nmap -p 22,80,443 192.168.1.0/24 - Targeted port scanning
x nmap -O --traceroute target.com - OS detection with traceroute
ARP Table Management (arp)
Enhanced ARP cache analysis with multiple output formats.
Usage: x arp [flags]
Key features:
Interactive TUI application for ARP table viewing
Multiple output formats (CSV, TSV, TUI)
MAC address vendor lookup
Suspicious entry detection
Complete ARP table display
Examples:
x arp - Auto-detect output format (TUI/TSV)
x arp --all - Show all ARP entries including incomplete
x arp --csv - CSV format output
x arp --app - Interactive TUI application
DNS Configuration (dns)
Domain Name System management and troubleshooting.
Usage: x dns [subcommand]
Key subcommands:
current - View current DNS configuration
ls - List available DNS servers
refresh - Flush DNS cache
set - Configure DNS settings (experimental)
Examples:
x dns - View current DNS configuration
x dns current - Detailed DNS configuration
x dns refresh - Flush DNS cache
x dns ls - List available DNS servers
Routing Table Analysis (route)
Enhanced routing table management and analysis.
Usage: x route [subcommand]
Key features:
Route table display and analysis
Multiple output formats
Experimental status with ongoing development
Examples:
x route - Display routing table
x route --csv - CSV format output
x route ls - List routing information
Enhanced ICMP Ping (ping)
Advanced ping utility with visualization capabilities.
Usage: x ping [flags] [target]
Key features:
Default ping to bing.com for quick testing
Heatmap visualization of ping results
Bar chart display of latency data
Multiple output formats (CSV, TSV, raw)
Visual processing of existing ping data
Examples:
x ping - Default ping to bing.com
x ping 8.8.8.8 - Ping specific target
x ping --heatmap 8.8.8.8 - Heatmap visualization
x ping --bar google.com - Bar chart display
ping google.com | x ping vis --heatmap - Process existing ping data
TCP Port Ping (tping)
TCP-based connectivity testing for service availability.
Usage: x tping [flags] [target:port]
Key features:
TCP connectivity testing using curl
Default port 80 testing
Heatmap and bar chart visualizations
Multiple output formats
Integration with cosmo curl for better compatibility
Examples:
x tping bing.com - TCP ping to port 80
x tping --heatmap bing.com - Heatmap visualization
x tping --bar bing.com:80 - Bar chart display
x tping google.com:443 - Test HTTPS connectivity

Installation and Setup
Prerequisites
x-cmd CLI installed
Network connectivity for external testing
Appropriate permissions for network scanning
Platform-Specific Requirements
Network Scanning (nmap)
Nmap installation required for full functionality
Administrator/root privileges for certain scan types
Network interface access for raw packet operations
DNS Management
Works across all platforms
May require administrative privileges for configuration changes
Internet connectivity for external DNS testing
Enhanced Ping Utilities
Works across all platforms
No special privileges required for basic functionality
Terminal support for visualizations
Configuration
Nmap Integration
# Verify nmap installation
x nmap --help
DNS Configuration
# Check current DNS settings
x dns current
Network Interface Setup
# View ARP table for network analysis
x arp --app
Integration with Other Tools
Data Processing
Pipe output to x jq for JSON processing
Use with @zh for Chinese translation of network data
Export to CSV/TSV for spreadsheet analysis
Security Integration
Combine with x shodan for external network intelligence
Use with x osv for vulnerability correlation
Integrate with x kev for known vulnerability checking
Monitoring and Automation
Combine with shell scripts for automated network monitoring
Schedule regular network health checks
Create custom network diagnostic workflows
Troubleshooting
Common Issues
Permission errors: Ensure appropriate privileges for network operations
Network connectivity: Verify internet connection for external testing
Scan limitations: Some nmap features require elevated privileges
DNS resolution: Check network configuration for DNS issues
Performance Optimization
Use specific scan targets rather than broad ranges
Limit scan intensity for production networks
Cache results when appropriate for monitoring
Use visual interfaces for complex analysis
Security Considerations
Responsible scanning: Only scan networks you own or have permission to test
Legal compliance: Ensure network scanning complies with local laws
Rate limiting: Respect network resources and avoid aggressive scanning
Documentation: Maintain records of authorized network testing
