Linux23: Connectivity Check

Before you touch remote systems, you need to confirm what you can reach and how a service is actually responding

Objective

Learner can check local IP configuration, test host reachability, and perform HTTP health checks

Mission

A service on app-srv-03 is reported unreachable. Verify: (1) your own workstation's local network configuration, (2) whether internal-status.solvinme.local is reachable, (3) the exact HTTP status code returned on port 8080. Submit your answer as two words separated by a space: the reachability result (reachable or unreachable) followed by the HTTP status code you found.

Commands you may need to solve this lab

ip addrpingcurl -I

Questions

1. Which modern command displays network interface configurations and IP assignments?

2. Which ICMP utility tests network reachability and latency to a destination host?

3. How do you fetch HTTP response headers only without downloading the response payload?
