Hulios: An eBPF-powered, transparent Tor gateway for Linux
Hulios is a new open-source tool for Linux that uses eBPF technology to route network traffic through the Tor network. It provides a transparent, leak-resistant VPN-like gateway for users seeking enhanced privacy.
Why it matters
Offers a technical solution for privacy-conscious Linux users to secure their network traffic at the kernel level.
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.
Hulios implements a strict privilege-separated runtime model:
Linux Kernel: Version 5.10 or higher. Kernel Configs: CONFIG_BPF_SYSCALL , CONFIG_BPF_LSM , and CONFIG_CGROUPS_V2 must be enabled. Build Dependencies: clang and libelf (required for compile-time eBPF compilation). Verified Platforms Tested and verified on Arch Linux and Debian 13 (Bookworm) .
📦 Arch Linux (AUR) Hulios is available on the Arch User Repository as hulios-git :
