Hulios: An eBPF-powered, transparent Tor gateway for Linux
TL;DR
Hulios is a transparent Tor VPN gateway for Linux that uses eBPF to secure outbound traffic without altering system configurations. It achieves robust leak resistance through a privilege-separated architecture and localized DNS resolution.
✦ Why It Matters
Implement Hulios to enhance your Linux system's privacy without complex configurations.
Key Takeaways
- Install Hulios from the Arch User Repository or build from source.
- Ensure your Linux kernel is version 5.10 or higher.
- Customize the generated config.toml for preferred settings.
- Use the Tor Browser for enhanced anonymity while browsing.
How It Works
Hulios operates at the kernel level using eBPF to intercept and redirect TCP sockets and DNS queries. It employs cgroup hooks and policy routing to create a secure environment that prevents data leaks without altering system configurations.
The supervisor process manages routing policies while the worker process handles traffic, ensuring that any potential vulnerabilities are mitigated through privilege separation.
