Abstract
Fpnd is an open-source Cybersecurity & Ethical Hacking project. Python package for freepn network daemon. The FreePN network daemon (fpnd) is a P2P implementation of a distributed virtual private network (dVPN) that creates an anonymous "cloud" of peers where each peer is both a client node and an exit node. Peers are randomly connected on startup and reconnected to new (random) peers as needed. It is built using Python. The complete source code is publicly available on GitHub under the GNU Affero General Public License v3.0, making it a useful reference for students building a Cybersecurity & Ethical Hacking mini project or final-year project.
1. Introduction
The FreePN network daemon (fpnd) is a P2P implementation of a distributed virtual private network (dVPN) that creates an anonymous "cloud" of peers where each peer is both a client node and an exit node. Peers are randomly connected on startup and reconnected to new (random) peers as needed.

Once installed, the above packages should update normally along with any other updated system packages (both @world and dependencies). It's very important to keep all your system packages up to date, and especially important when running an alpha release (eg, fpnd-0.9.x) since (software) interfaces may (and probably will) break between releases. Both Gentoo and Ubuntu have ways to notify you when you have updates waiting (or at least when your package tree is getting stale).
2. Objective
Python package for freepn network daemon
This project demonstrates how Python can be applied to a real-world Cybersecurity & Ethical Hacking problem.

7. Future Enhancements
Suggested extensions you can add to make this your own project.
- Add logging and alert notifications (email / Telegram)
- Write a threat model document for the tool
- Package it with Docker for safe lab testing
8. Viva / Review Questions
Common questions examiners ask for projects in this domain.
- Which threat or attack does this project defend against?
- What detection or protection technique is used and what are its limits?
- How are false positives and false negatives handled?
- Which cryptographic algorithms or security standards are involved?
- What legal and ethical rules apply when testing a tool like this?
