TLDR

A Rust rewrite of the Shadowsocks proxy that tunnels your internet traffic through an encrypted connection to bypass firewalls and network restrictions, faster and more reliable than the original.

Requires a server on an unrestricted network plus Rust/Cargo toolchain to build, correct firewall port configuration needed on both client and server.

In plain English

Shadowsocks is a proxy protocol designed to help users route their internet traffic through an encrypted tunnel and bypass network restrictions such as firewalls. This repository is a reimplementation of the original shadowsocks software, rewritten in Rust for better performance and reliability. The way it works is: you run a server component on a machine outside the restricted network, and a local client component on the machine you want to use. Traffic from the local machine passes through the encrypted tunnel to the server, then out to the open internet. From the outside, the traffic looks like ordinary encrypted data rather than a recognizable proxy connection, which is how it avoids detection by many firewall systems. This Rust version is organized as several separate libraries. The core protocol logic lives in one library, the service layer that manages running the client and server processes lives in another, and the final package bundles the command-line binaries together. You can install the binaries through Cargo, which is Rust's package manager, or through system package managers on Linux distributions like Arch Linux and NixOS. It is also available via Homebrew on macOS and as a Snap package. The README covers a range of optional build features, including different DNS resolver backends, support for the HTTP and QUIC protocols locally, and DNS-over-HTTPS and DNS-over-TLS. Several community-maintained graphical clients for Linux, Windows, and routers running OpenWRT are linked as related projects. The full README is longer than what was shown.

Copy-paste prompts

Prompt 1
I have a VPS outside my country's firewall. Walk me step by step through installing shadowsocks-rust on the server and configuring a local client to tunnel my browser traffic through it.
Prompt 2
What is the minimal config file I need for a shadowsocks-rust server and client? Show me the JSON with the important fields explained.
Prompt 3
How do I build shadowsocks-rust from source using Cargo on Ubuntu, including enabling the DNS-over-HTTPS feature?
Prompt 4
How do I set up shadowsocks-rust on an OpenWRT router so all devices on my home network automatically use the tunnel?
