🔒 Device Access Locker

"Block specific apps and platforms on selected devices in your LAN using iptables, ARP spoofing, and DNS overrides."

---

⚡ What is this?

This project provides a Python-based network locker that allows you to block access to certain platforms (e.g., Roblox, TikTok, Facebook) for specific devices on your network.

It works by:

1. Running ARP spoofing to redirect traffic through your machine.
2. Applying iptables rules to drop connections to known IP ranges.
3. Adding DNS overrides in /etc/hosts for target domains.
4. Restarting resolvers to enforce changes.

When you unlock, all changes are reverted.

🚨 Disclaimer

• Requires root privileges (sudo).
• Uses iptables and ARP spoofing (via bettercap).
• Designed for local testing, parental control, or network management.
• Misuse (e.g., blocking others’ traffic without consent) may be illegal. You are responsible for your use.

📂 Structure

• BaseLocker → Core class with lock/unlock logic.
• Roblox, TikTok, Facebook → Predefined service blockers (DNS + IP ranges).
• BaseMixinInfo → Example device list (target_devices_list).

You can create your own blockers by defining new classes with:

• dns_list (domains to block)
• ip_list (IP ranges to block)

---

⚙️ Requirements

• Python 3.10+
• bettercap (installed and accessible in ~/Programs/bettercap)
• Linux with iptables and systemd-resolved

---

🚀 Usage

1. Configure your target device(s)

Edit BaseMixinInfo or subclass it:

class BaseMixinInfo:
    target_devices_list = ["192.168.1.110"]  # Replace with your device IP

2. Run a blocker

Example: block Roblox for the target device

roblox = Roblox()
roblox.lock()

3. Unlock (restore access)

roblox.unlock()

---

🛠️ Extending

To add a new platform:

class YouTube(BaseMixinInfo, BaseLocker):
    dns_list = ["youtube.com", "www.youtube.com"]
    ip_list = ["142.250.0.0/16"]

Then run:

yt = YouTube()
yt.lock()
