Frequently Asked Questions about network-diagnostics

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

FAQPage Schema
How do I diagnose network connectivity issues to a specific website?

To diagnose network connectivity issues, this Skill runs systematic ping tests, DNS resolution checks, and traceroutes to pinpoint whether the problem is latency, routing, or service availability.

Why does DNS resolution fail when I try to access a website?

DNS resolution failures during website access are identified by this Skill through automated DNS lookups, verifying if the domain correctly resolves to an IP address or if a local resolver issue exists.

What is the best way to check if a specific network port is open?

The best way to check if a network port is open is using this Skill's port connectivity checks, which verify service availability and confirm if web services are actively responding on the target.

Can I use traceroute to find the cause of network latency problems?

Yes, you can use traceroute to find the cause of network latency problems, as this Skill executes the traceroute utility to analyze routing paths and identify where connection delays occur.

Do I need any external network utilities installed to run these diagnostics?

Yes, you need standard system network utilities installed, because this Skill requires execution of underlying system commands like ping and traceroute to perform its detailed connectivity analysis.
