Config Files (part 4) · DNS Labs tutorial

Runnable lab for this step

This lesson explains the ideas. The matching GitHub folder is a lab snapshot you can clone and run. Skim the scripts, run the checks, then come back here for the why.

Open snapshot on GitHub

fcc-net-dns/04-Config-Files

Run locally

git clone https://github.com/michaeldunga1/fcc-net-dns.git
cd fcc-net-dns/04-Config-Files
bash check.sh || true
cat README.md
