network-connectivity-troubleshooter

Diagnose network reachability by running guided, read-only checks across local and remote vantage points. The troubleshooter analyzes interface state, routing tables, and TCP connectivity to pinpoint where packets drop between your local shell and remote hosts.

Troubleshoot VPN and proxy connectivity by checking local versus remote reachability differences. The tool validates name resolution and tests gateway paths to identify misconfigurations causing intermittent network symptoms.

Check packet loss and latency using safe read-only commands like ping and traceroute. The diagnostic tool measures response times and hop-by-hop delays to isolate high-latency links or dropped packets across your routing path.

Yes, the network troubleshooter supports read-only MTU diagnostics. It uses safe guardrails with standard commands like ip route and simple TCP tests to identify maximum transmission unit symptoms without modifying system configurations.

DNS resolution fails when local name servers cannot map hostnames to IP addresses. The troubleshooter verifies DNS health using getent hosts and nslookup, comparing results against direct IP connectivity to separate resolution failures from routing blocks.

Yes, you can validate network health across local Windows shells and remote SSH sessions. The tool executes interface and route analysis from multiple vantage points to identify whether connectivity breaks locally or on the remote path.
