Task 1: Preparation

You can find the starter files in the directory: switchyard/examples/exercises/firewall. Let's start with it.

1. Create a directory named lab_7 in switchyard.
2. Copy examples/exercises/firewall/start_mininet.py to lab_7/start_mininet.py.
3. Copy examples/exercises/firewall/firewall.py to lab_7/firewall.py.
4. Copy examples/exercises/firewall/firewalltests.py to lab_7/firewalltests.py.
5. Copy examples/exercises/firewall/www/start_webserver.sh to lab_7/www/start_webserver.sh.
6. Download the rules text file firewall_rules.txt into the folder lab_7.

Finally, your project will look like

switchyard

  ├─.../
