17.2.4Lab: Informational and Network Tools

🔧 Linux Network Troubleshooting Lab | Tracing Network Routes with Terminal

In this lab walkthrough, we troubleshoot a performance issue on a Linux system named IT-Laptop that is experiencing slow connectivity when accessing a remote computer on the internet. Using the Linux Terminal, we analyze the network path (route) traffic takes to reach both an external DNS server and an internal remote host.

This exercise focuses on understanding network routing, hops, and troubleshooting connectivity issues using Linux command-line tools.

🧪 Lab Objectives Covered:

Locate the external DNS server IP address using provided network exhibits

Determine the network route to the external DNS server

Analyze hop-by-hop routing information to answer lab questions

Trace the route to a remote internal computer (10.10.20.10)

Compare external vs internal network paths

🛠️ Tools & Commands Used:

Linux Terminal

traceroute / tracepath

Network exhibits and routing analysis

📚 Skills Practiced:

Linux command-line navigation

Network diagnostics and troubleshooting

Understanding hops, gateways, and routing paths

Identifying performance bottlenecks in network communication

This lab is ideal for students and entry-level IT professionals learning Linux networking, system administration, or help desk troubleshooting concepts.
