Tor Router

A SOCKS, HTTP and DNS proxy for distributing traffic across multiple instances of Tor.
NPM
FOSSA Status
Tor Router is a SOCKS5, DNS and HTTP proxy server for distributing traffic across multiple instances of Tor. At startup Tor Router will run an arbitrary number of instances Tor and each request will be sent to a different instance in round-robin fashion. This can be used to increase anonymity, because each request will be sent on a different circuit and will most likely use a different exit-node, and also to increase performance since outbound traffic is now split across several instances of Tor.
A list of changes can be found here.

Building and Running

The only installation requirement is node.js. Tor is bundled with the application. To use an external Tor executable use the --torPath command line switch or set the TOR_PATH environment variable.
To install run: npm install To start run: bin/tor-router
To install globally run: npm install -g tor-router
Alternatively docker can be used. The build will retrieve the latest version of Tor from the offical Tor Project repository.
To build run: docker build -t znetstar/tor-router . To start run: docker run --rm -it -p 9050:9050 znetstar/tor-router

Usage

The following command line switches and their environment variable equivalents are available for use:
If just a port number is passed in place of a host, it will bind to all interfaces.
Command line switchEnvironment VariableDescription
-f, --configPath to a JSON configuration file to use
-c, --controlHostCONTROL_HOSTHost the control server will bind to and listen for TCP traffic (see below)
-w, --websocketControlHostWEBSOCKET_CONTROL_HOSTHost the control server will bind to and listen for WebSocket traffic
-j, --instancesINSTANCESNumber of Tor instances to spawn
-s, --socksHostSOCKS_HOSTHost the SOCKS proxy will bind to
-d, --dnsHostDNS_HOSTHost the DNS proxy will bind to
-h, --httpHostHTTP_HOSTHost the HTTP proxy will bind to
-l, --logLevelLOG_LEVELLog level (defaults to "info") set to "null" to disable logging. To see a log of all network traffic set logLevel to "verbose"
-p, --parentDataDirectoryPARENT_DATA_DIRECTORYParent directory that will contain the data directories for the instances
-b, --loadBalanceMethodLOAD_BALANCE_METHODMethod that will be used to sort the instances between each request. Currently supports "round_robin" and "weighted".
-t, --torPathTOR_PATHProvide the path for the Tor executable that will be used
-n, --proxyByNamePROXY_BY_NAMEControls how authenticated requests will be handled. Can be set to "individual", "group" or false to disable
A full list of all available configuration options and their defaults can be found in default_config.js
For example: tor-router -j 3 -s 127.0.0.1:9050 would start the proxy with 3 tor instances and listen for SOCKS connections on localhost:9050.
