SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

Network administrators and developers need fast, OS-agnostic diagnostics to verify reachability, DNS resolution, and port status across devices. This Skill consolidates common network checks into a single workflow to speed issue isolation and reduce tool-switching.

Core Features & Use Cases

  • Reachability and connectivity checks (ping, traceroute, curl) across Linux, macOS, and Windows.
  • DNS resolution and reverse lookup (dig/nslookup, nslookup) to validate name-to-IP mappings.
  • Port and service checks (tcp connect, HTTP/SSL) to verify remote services are reachable.
  • Use Case: When a host is intermittently unreachable, run automated diagnostics to identify whether the issue is DNS, routing, firewall, or a service port.

Quick Start

Run a target through the network diagnostics workflow to detect OS, select commands, and generate a concise report.

Frequently Asked Questions about network

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I troubleshoot network connectivity issues across different operating systems?▼

Network connectivity troubleshooting is performed by detecting the host OS and selecting appropriate commands like ping, traceroute, and curl to verify reachability across Linux, macOS, and Windows environments.

Can I run DNS lookups and reverse mappings to diagnose name resolution problems?▼

DNS lookups and reverse mappings are executed using dig or nslookup to validate name-to-IP mappings, allowing you to quickly identify whether resolution errors are causing your network connectivity failures.

How do I check remote port availability and HTTP/SSL status for a specific host?▼

Port availability and HTTP/SSL diagnostics are checked by executing tcp connect tests and openssl commands, verifying if remote services are reachable and identifying firewall or certificate issues.

Does this network diagnostics approach work on Windows, or do I need separate Linux tools?▼

This network diagnostics approach works on Windows natively by detecting the OS and automatically selecting appropriate Windows commands, eliminating the need for separate Linux tools to perform reachability checks.

What is the best way to diagnose an intermittently unreachable host?▼

The best way to diagnose an intermittently unreachable host is to run an automated network diagnostics workflow that tests DNS, routing, and service ports concurrently to isolate the specific failure point.

Why do I get varying results when switching between dig and nslookup for DNS diagnostics?▼

Varying results between dig and nslookup during DNS diagnostics occur due to differing tool availability across operating systems, which this workflow handles by validating prerequisites and selecting the appropriate command.
