Hulios: An eBPF-powered, transparent Tor gateway for Linux
Hulios Hardened Universal Linux Invisibility and Onion System Hulios is an eBPF-powered, transparent Tor VPN gateway for Linux. It secures outbound network traffic by redirecting TCP sockets and DNS queries through an embedded Arti (Tor client) instance and a localized Hickory-based DNS resolver. Sandbox Isolation: The worker process drops privileges to nobody and is isolated using a restrictive seccomp system call filter.

Opening excerpt (first ~120 words) tap to expand
Hulios Hardened Universal Linux Invisibility and Onion System Hulios is an eBPF-powered, transparent Tor VPN gateway for Linux. It secures outbound network traffic by redirecting TCP sockets and DNS queries through an embedded Arti (Tor client) instance and a localized Hickory-based DNS resolver. By operating at the kernel socket level via cgroup hooks and policy routing, Hulios implements robust leak-resistant boundaries without modifying runtime resolv.conf configurations or relying on external firewall daemons. 🔒 Security Architecture Hulios implements a strict privilege-separated runtime model: Privilege Separation: The entry point supervisor runs with host root privileges to hook eBPF programs and build policy routing tables, then immediately spawns an unprivileged worker child.
