Expand description

A minimal command line program for connecting to the tor network

(If you want a more general Tor client library interface, use arti_client.)

This crate is the primary command-line interface for Arti, a project to implement Tor in Rust. Many other crates in Arti depend on it.

Note that Arti is a work in progress; although we’ve tried to write all the critical security components, you probably shouldn’t use Arti in production until it’s a bit more mature.

More documentation will follow as this program improves. For now, just know that it can run as a simple SOCKS proxy over the Tor network. It will listen on port 9150 by default, but you can override this in the configuration.

Command-line interface

(This is not stable; future versions will break this.)

arti uses the clap crate for command-line argument parsing; run arti help to get it to print its documentation.

The only currently implemented subcommand is arti proxy; try arti help proxy for a list of options you can pass to it.

Configuration

By default, arti looks for its configuration files in a platform-dependent location.

OSConfiguration File
Unix~/.config/arti/arti.toml
macOS~/Library/Application Support/arti/arti.toml
Windows\Users\<USERNAME>\AppData\Roaming\arti\arti.toml

The configuration file is TOML. (We do not guarantee its stability.) For an example see arti_defaults.toml.

Compile-time features

tokio (default): Use the tokio runtime library as our backend.

async-std: Use the async-std runtime library as our backend. This feature has no effect unless building with --no-default-features to disable tokio.

native-tls – Build with support for the native_tls TLS backend. (default)

rustls – Build with support for the rustls TLS backend.

static – Link with static versions of your system dependencies, including sqlite and/or openssl. (⚠ Warning ⚠: this feature will include a dependency on native-tls, even if you weren’t planning to use native-tls. If you only want to build with a static sqlite library, enable the static-sqlite feature. We’ll look for better solutions here in the future.)

static-sqlite – Link with a static version of sqlite.

static-native-tls – Link with a static version of native-tls. Enables native-tls.

Limitations

There are many missing features. Among them: there’s no onion service support yet. There’s no anti-censorship support. You can’t be a relay. There isn’t any kind of proxy besides SOCKS.

See the README file for a more complete list of missing features.

Library for building command-line client

This library crate contains code useful for making a command line program similar to arti. The API should not be considered stable.

Modules

Configuration for the Arti command line application

Implement a simple DNS resolver that relay request over Tor.

Detect a “ctrl-c” notification or other reason to exit.

Configure tracing subscribers for Arti

Code to adjust process-related parameters.

Code to watch configuration files for any changes.

Functions

Main program, callable directly from a binary crate’s main

Inner function to allow convenient error handling

Run the main loop of the proxy.
