ruby-sockets

Installing

Recommended

gem install sockets

Edge

git clone https://github.com/samuelkadolph/ruby-sockets
cd ruby-sockets && rake install

Rationale

This gem was created for 2 purposes.

First is to enable ruby programmers to use HTTP or SOCKS proxies interchangeably when using TCPSockets. Either manually with Sockets::Proxy#open or by require "sockets/env".

The second purpose is to use ruby code that doesn't consider a proxy for users that have to use proxies.
The pruby and pirb executables are simple wrappers for their respective ruby executables that support proxies from environment variables.

Usage

Environment Variables & Executable Wrappers

sockets provides two executables: pruby and pirb. They are simple wrappers for your current ruby and irb executables that require "sockets/env" which installs hooks to TCPSocket which will use your proxy environment variables whenever a TCPSocket is created. sockets will use the proxy, PROXY, socks_proxy and http_proxy environment variables (in that order) to determine what proxy to use.

Ruby

require "sockets/proxy"

proxy = Sockets::Proxy("socks://localhost")
socket = proxy.open("www.google.com", 80)
socket << "GET / HTTP/1.1\r\nHost: www.google.com\r\n\r\n"
socket.gets # => "HTTP/1.1 200 OK\r\n"

Supported Proxies

Protocol	Formats	Notes
HTTP	http://[username[:password]@]host[:port][?tunnel=false]	The port defaults to 80. This is currently a limitation that may be solved in the future. Appending ?tunnel=false forces the proxy to not use CONNECT.
SOCKS5	socks://[username[:password]@]host[:port] socks5://[username[:password]@]host[:port]	Port defaults to 1080.
SOCKS4	socks4://[username@]ip1.ip2.ip3.ip4[:port]	Currently hangs. Not sure if the problem is with code or server.
SOCKS4A	socks4a://[username@]host[:port]	Not yet implemented.
