EventMachine implements a fast, single-threaded engine for arbitrary network communications. It's extremely easy to use in Ruby. EventMachine wraps all interactions with IP sockets, allowing programs to concentrate on the implementation of network protocols. It can be used to create both network servers and clients. To create a server or client, a Ruby program only needs to specify the IP address and port, and provide a Module that implements the communications protocol. Implementations of several standard network protocols are provided with the package, primarily to serve as examples. The real goal of EventMachine is to enable programs to easily interface with other programs using TCP/IP, especially if custom protocols are required.

Socketry wraps Ruby's sockets with an advanced timeout engine which is able to provide multiple simultaneous timeout behaviors in a thread-safe way.

SocketHarness is a test utilities that helps implement Test Harness pattern from the book "Release it!". It seats between application and integration server to simulate odd network/application behaviors, e.g. slow network.

The Ruby Exploitation (Rex) Socket Abstraction Library. This library includes all of the code needed to turn sockets into Rex::Sockets with the functionality for things like L3 pivoting used by Metasploit.

Background worker to send Apple Push Notifications over a persistent TCP socket. Includes Resque tweaks to allow persistent sockets between jobs, helper methods for enqueueing APN notifications, and a background daemon to send them.

Over and over I see developers struggling to implement basic sockets with featues available on ruby socket stdlib. easy_sockets, takes care of basic details that usually are overlooked by developers when implementing TCP/Unix sockets from scratch.

Socketry::Async provides a modern asynchronous I/O framework for Ruby based on the Socketry, promise.rb, nio4r gems

SocketPool class to mangage socket based client access [based on MongoDB pool class]

The official SocketServ API Ruby client

The sctp-socket library provides Ruby bindings for SCTP sockets. is a message oriented, reliable transport protocol with direct support for multihoming.

SocketLabs Email Delivery Ruby Client library

This library enables communication between processes using Unix sockets. It handles message transmission, socket management, and cleanup, supporting both synchronous and asynchronous operations while providing error handling for robust development.

A socketcluster client designed in ruby

This is a simple Ruby-based policy server to serve Flash's crossdomain.xml policy file. The web is increasingly realtime, but websockets still aren't supported on older browser clients. Many server push libraries (e.g. socket.io) attempt to use websockets, with a Flash fallback. Others (amqp.js, for instance) are Flash only. When using Flash sockets, it's necessary to have a policy server running on port 843, in order to set cross domain policy. This library does the job.

Very small and simple gem that makes using websockets really easy.

SocksHandler is a flexible socksifier for sockets created by `TCPSocket.new`, `Socket.tcp` or UDPSocket.new that solves the following issues: 1) `SOCKSSocket` is not easy to use, 2) Famous socksifiers such as socksify and proxychains4 don't support rules using domain names.
