This project has been created as part of the 42 curriculum by enchevri.
In this 42 school project, no coding is required. The goal is to learn networking basics using the NetPractice web tool.
This tool helps you understand how simple networks work by configuring IPv4 addresses and subnet masks for different hosts and routers. You must connect all devices while following the network rules given in each level.
The program is not connected to the net, you can train freely without any concern.
- Python 3 installed
- Modern web browser (Firefox, Chrome, etc.)
- The NetPractice archive from the 42 intranet
- Download the NetPractice archive from the 42 intranet
- Extract the files in a directory of your choice
- Run the script:
./run.sh
- Enter your 42 login on the main page
- Choose Training tab for levels 1-10 in order
- Or use Evaluation tab for random levels 7-10 (good for practice too!)
- For each level, configure IPs/masks until objectives are met
- Click Check again to validate
- (You can check for console debug on the bottom right of the screen)
- For each solved level, click Get my config to download the file
- You need 10 config files total (one per level)
- Place all 10 files at the root of your Git repository
This project covers essential networking fundamentals including:
- IPv4 Addressing: Understanding IP address classes, address structure, and assignment methods
- Subnet Masks: CIDR notation, subnet calculations, determining network and broadcast addresses
- Default Gateways: Router configuration and routing between subnets
- Routers and Switches: Differences in functionality and network layer operations
- Network Segmentation: Dividing networks into subnets, calculating available hosts
- IP Routing: Direct and indirect routing, route determination based on routing tables
- Networking Fundamentals: A full playlist of videos that helps me understand how a network works and a lot more.
- Subnet Cheat Sheet: Quick reference for subnet calculations and IP addressing
AI was used to reformulate and structure everything in this README to ensure that the concepts are clearly explained.
