  • DNS configuration verification and testing
  • Connectivity tests and port checks
  • Firewall/routing inspection and service status validation

Quick Start

  1. Run through MTU, DNS, and connectivity checks
  2. Apply recommended fixes and save rollback scripts
  3. Validate changes with a follow-up test

Frequently Asked Questions about network-diagnostics

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

FAQPage Schema
How do I diagnose DNS resolution issues in WSL or Linux?

DNS resolution problems can be diagnosed by checking your DNS configuration and running query tests. This Skill verifies DNS settings and tests resolution using dig or nslookup to identify configuration failures, service status issues, or connectivity blocks affecting name lookup.

Can I fix MTU issues in WSL automatically?

Yes. This Skill adjusts MTU settings for WSL and native Linux, tests the changes to confirm they resolve connectivity or fragmentation issues, and generates rollback scripts so you can revert if needed.

How do I test firewall and routing rules on Linux?

Firewall and routing troubleshooting uses command-driven checks including iptables inspection, route table analysis, and port connectivity tests. This Skill runs these checks, identifies blocked routes or ports, and produces scripts to apply verified fixes.

What's the fastest way to verify network connectivity and port accessibility?

This Skill runs structured connectivity tests using traceroute, nc, and telnet to check end-to-end paths and port availability, then generates reproducible remediation scripts distinguishing between WSL and native Linux environments.

Do I need to manually write network troubleshooting commands for WSL?

No. This Skill automates command generation for MTU, DNS, connectivity, firewall, and service checks, accounting for WSL-specific constraints, and produces ready-to-run remediation scripts with built-in rollback capability.

How do I validate network changes without breaking my configuration?

After applying fixes, this Skill runs follow-up validation tests and saves rollback scripts before making changes, so you can revert safely if adjustments cause issues or don't resolve the problem.
