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.

== DESCRIPTION: The RightScale AWS gems have been designed to provide a robust, fast, and secure interface to Amazon EC2, EBS, S3, SQS, SDB, and CloudFront. These gems have been used in production by RightScale since late 2006 and are being maintained to track enhancements made by Amazon. The RightScale AWS gems comprise: - RightAws::Ec2 -- interface to Amazon EC2 (Elastic Compute Cloud) and the associated EBS (Elastic Block Store) - RightAws::S3 and RightAws::S3Interface -- interface to Amazon S3 (Simple Storage Service) - RightAws::Sqs and RightAws::SqsInterface -- interface to first-generation Amazon SQS (Simple Queue Service) (API version 2007-05-01) - RightAws::SqsGen2 and RightAws::SqsGen2Interface -- interface to second-generation Amazon SQS (Simple Queue Service) (API version 2008-01-01) - RightAws::SdbInterface and RightAws::ActiveSdb -- interface to Amazon SDB (SimpleDB) - RightAws::AcfInterface -- interface to Amazon CloudFront, a content distribution service == FEATURES: - Full programmmatic access to EC2, EBS, S3, SQS, SDB, and CloudFront. - Complete error handling: all operations check for errors and report complete error information by raising an AwsError. - Persistent HTTP connections with robust network-level retry layer using RightHttpConnection). This includes socket timeouts and retries. - Robust HTTP-level retry layer. Certain (user-adjustable) HTTP errors returned by Amazon's services are classified as temporary errors. These errors are automaticallly retried using exponentially increasing intervals. The number of retries is user-configurable. - Fast REXML-based parsing of responses (as fast as a pure Ruby solution allows). - Uses libxml (if available) for faster response parsing. - Support for large S3 list operations. Buckets and key subfolders containing many (> 1000) keys are listed in entirety. Operations based on list (like bucket clear) work on arbitrary numbers of keys. - Support for streaming GETs from S3, and streaming PUTs to S3 if the data source is a file. - Support for single-threaded usage, multithreaded usage, as well as usage with multiple AWS accounts. - Support for both first- and second-generation SQS (API versions 2007-05-01 and 2008-01-01). These versions of SQS are not compatible. - Support for signature versions 0 and 1 on SQS, SDB, and EC2. - Interoperability with any cloud running Eucalyptus (http://eucalyptus.cs.ucsb.edu) - Test suite (requires AWS account to do "live" testing).

Rightscale::HttpConnection is a robust HTTP/S library. It implements a retry algorithm for low-level network errors. == FEATURES: - provides put/get streaming - does configurable retries on connect and read timeouts, DNS failures, etc. - HTTPS certificate checking

A Jekyll plugin to add metadata tags for search engines and social networks to better index and display your site's content.

A Ruby implementation of SNMP (the Simple Network Management Protocol).

Ruby extension for Network Kanji Filter

This plugin provides native network instrumentation for monitoring and metrics collection, including: hardware, TCP response, RBLs, whois, port status, and more

Library for packed binary data stored in ruby Strings. Useful for accessing fields in network packets and binary files.

PacketFu is a mid-level packet manipulation library for Ruby. With it, users can read, parse, and write network packets with the level of ease and fun they expect from Ruby.

This gem was originally added to the Metasploit Pcaprub gem. It's been spun out into its own gem for anyone who might want to programmatically get information on their network interfaces.

Recog is a framework for identifying products, services, operating systems, and hardware by matching fingerprints against data returned from various network probes. Recog makes it simply to extract useful information from web server banners, snmp system description fields, and a whole lot more.

Ruby/GIO2 provide Ruby binding to a VFS API and useful APIs for desktop applications (such as networking and D-Bus support).

Microsoft Azure Network Management Client Library for Ruby

Checks if a IP or hostname would cause a request to a private network (RFC 1918)

Provides an OOP interface to docker-compose and facilitates container-to-host and host-to-container networking.

This gem wraps the ZeroMQ networking library using the ruby FFI (foreign function interface). It's a pure ruby wrapper so this gem can be loaded and run by any ruby runtime that supports FFI. That's all of the major ones - MRI, Rubinius and JRuby.
