SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes scripts (resource) and references (resource) components.

What problem does it solve?

This skill addresses the difficulty of diagnosing complex, intermittent Linux network issues by providing a structured, kernel-level diagnostic workflow that avoids blind troubleshooting.

Core Features & Use Cases

  • Kernel-Level Probing: Utilizes specialized X-diagnosis tools to trace protocol stack behavior, RST triggers, and virtio queue states.
  • Evidence-Based Analysis: Enforces a strict diagnostic pipeline that correlates OS-level counters with deep kernel insights to ensure root cause accuracy.
  • Use Case: When a production service experiences intermittent TCP connection resets, this skill guides the user to capture the exact kernel call stack responsible for the RST packet, identifying whether the issue originates from local firewall rules or remote peer behavior.

Quick Start

Execute the X-diagnosis network analysis skill to identify the root cause of the current TCP connection reset issue on this host.

FAQPage Schema
How do I diagnose intermittent TCP connection resets in the Linux kernel?

Diagnosing intermittent Linux kernel TCP resets requires a kernel-level diagnostic workflow that captures the exact call stack responsible for the RST packet. This approach correlates OS-level counters with deep kernel insights to identify if the issue originates from local firewall rules or remote peer behavior.

What is the best way to trace packet loss at the Linux kernel network stack?

Tracing Linux kernel packet loss requires evidence-based analysis using specialized diagnostic tools. By enforcing a strict diagnostic pipeline that traces protocol stack behavior, you can accurately identify the root cause of packet loss without leaving system artifacts.

How do I identify the root cause of virtual network queue congestion?

Identifying virtual network queue congestion root causes involves probing virtio queue states using deep-dive kernel-level diagnostics. This process correlates OS-level counters with deep kernel insights to target complex scenarios and ensure accurate root cause identification.

Does X-diagnosis-network-analysis work for production Linux environments?

X-diagnosis-network-analysis works for production Linux environments by providing a structured diagnostic workflow that avoids blind troubleshooting. It requires strict adherence to a multi-step verification protocol to ensure accurate root cause identification without leaving system artifacts.

Why does my TCP connection reset without an obvious application error?

A TCP connection reset without an obvious application error often stems from kernel-level RST triggers. Utilizing specialized kernel diagnostic tools to trace protocol stack behavior reveals whether the reset originates from local firewall rules or remote peer behavior.

When should I use kernel-level diagnostics instead of standard network troubleshooting?

You should use kernel-level diagnostics instead of standard network troubleshooting when facing complex, intermittent issues that resist conventional methods. A structured, evidence-based pipeline correlates deep kernel insights with OS-level counters to ensure root cause accuracy without blind guessing.
