TRACK 1 · NETWORK BASICS

Lab 02 · Link Lights

Before computers can talk, they need a physical connection, like a cable. The little light on each device shows whether that link works: green means yes, red means no. The network port inside a computer is called an interface, and it is usually named eth0.

What you will do

  1. Spot the dead light
  2. Prove it
  3. Ask the interface
  4. Bring it up
  5. Capture the flag
