Toralizer

A low-level network utility in C that transparently tunnels arbitrary TCP apps through a SOCKS4 proxy via LD_PRELOAD.

Overview

Toralizer is a lightweight networking tool that proxies TCP connections through a SOCKS server (targeting the Tor network) without modifying the application's source.

How it works

  • On Linux, it acts as a transparent proxy injector using `LD_PRELOAD` to wrap the `connect()` syscall.
  • On Windows, it runs as a standalone SOCKS4 diagnostic client for verifying connectivity and handshakes.
  • Native SOCKS4 handshake implementation, hardened build flags, and a smart cross-platform Makefile.

An educational systems/networking project.
