Shadowsocks Libev
shadowsocks-libev is an event-driven network daemon that provides an encrypted SOCKS5 proxy. It functions as a lightweight proxy server using a non-blocking event loop to route TCP and UDP traffic through encrypted tunnels to bypass network restrictions.
The project implements a transparent proxy gateway capable of intercepting outbound packets at the network layer, allowing system traffic to be redirected through the encrypted tunnel without per-application configuration. It also includes a daemon process manager to control multiple proxy server instances as child processes via local communication sockets.
The system covers a broad range of traffic management capabilities, including local port forwarding, encryption tunnel multiplexing, and the encapsulation of UDP datagrams within TCP streams. Access is managed through IP-based access control lists that permit or block client connections.
