Sockets tcp/ip communication library

C++ Sockets Library

This is a GPL licensed C++ class library wrapping the berkeley sockets C API, and therefore works on most unixes and also win32. The library is in use in a number of real world applications, both commercial and open source.

Features include, but are not limited to, SSL support, IPv6 support, tcp and udp sockets, sctp sockets, http protocol, highly customizable error handling. Testing has been done on Linux and Windows 2000, and to some part on Solaris and Mac OS X.

The Ultimate TCP-IP

（1）Easy To Use, Powerful Framework

  Includes both high-level and low-level APIs.

  No need to know Winsock programming. Work with the high level APIs to perform complex tasks with just a few lines of code.

  Works with MFC, ATL and Windows SDK applications.

  Fully object oriented, letting you create your own specialized Internet classes with ease.

  The library is 100% royalty free.

  Unlike other development components this framework is designed to work on all Win32 versions of Windows (i.e. not only NT).

  Create highly scalable servers (hundreds of connections per CPU) using our multi-threaded server framework.

  Create customized protocols for highly efficient data transfer.

（2）Includes Servers For The Most Popular Protocols

The Server edition of Ultimate TCP/IP includes the server-side implementations for the following protocols:

  Web Server (HTTP protocol).

  Finger server.

  Fully functional Email and relay server (SMTP, POP3, DNS)

  File transfer server (FTP)

  Echo server.

  *full source for each of the protocols is included

ACE

The ADAPTIVE Communication Environment (ACE) is a freely available, open-source object-oriented (OO) framework that implements many core patterns for concurrent communication software. ACE provides a rich set of reusable C++ wrapper facades and framework components that perform common communication software tasks across a range of OS platforms. The communication software tasks provided by ACE include event demultiplexing and event handler dispatching, signal handling, service initialization, interprocess communication, shared memory management, message routing, dynamic (re)configuration of distributed services, concurrent execution and synchronization.

ACE is targeted for developers of high-performance and real-time communication services and applications. It simplifies the development of OO network applications and services that utilize interprocess communication, event demultiplexing, explicit dynamic linking, and concurrency. In addition, ACE automates system configuration and reconfiguration by dynamically linking services into applications at run-time and executing these services in one or more processes or threads.

FTP Application

MiniFTP

MiniFTP is a Winsock API-based minimal FTP client to be used as a tutorial for using the Winsock API in an MFC environment.

gFTP

gFTP is a free multithreaded file transfer client for *NIX based machines.

KFTPgrabber is a graphical FTP client for the K Desktop Environment. It implements many features required for usable FTP interaction.

Pure-FTPd

Pure-FTPd is a free (BSD), secure, production-quality and standard-conformant FTP server. It doesn‘t provide useless bells and whistles, but focuses on efficiency and ease of use. It provides simple answers to common needs, plus unique useful features for personal users as well as hosting providers.

FileZilla

The free FTP solution. Both a client and a server are available. FileZilla is open source software distributed free.

Web Server Framework

（1）轻量级WebServer

lighttpd

Security, speed, compliance, and flexibility -- all of these describe lighttpd (pron. lighty) which is rapidly redefining efficiency of a webserver; as it is designed and optimized for high performance environments. With a small memory footprint compared to other web-servers, effective management of the cpu-load, and advanced feature set (FastCGI, SCGI, Auth, Output-Compression, URL-Rewriting and many more) lighttpd is the perfect solution for every server that is suffering load problems.

mongoose(shttpd)

Mongoose is an easy to use web server. It can be embedded into existing application to provide a web interface to it.

Features：

l  Crossplatform - works on Windows, MacOS and most flavors of UNIX

l  CGI, SSL, SSI, Digest (MD5) authorization, resumed download, aliases

l  IP-based ACL, Windows service, GET, POST, HEAD, PUT, DELETE methods

l  Small footprint: executable size is 40 kB on Linux 2.6 i386 system, 60 kB on Windows system

l  Embeddable with simple and clean API. Source is in single .c file to make things easy

thttpd

thttpd is a simple, small, portable, fast, and secure HTTP server.

Simple:

It handles only the minimum necessary to implement HTTP/1.1. Well, maybe a little more than the minimum.

Small:

See the comparison chart. It also has a very small run-time size, since it does not fork and is very careful about memory allocation.

Portable:

It compiles cleanly on most any Unix-like OS, specifically including FreeBSD, SunOS 4, Solaris 2, BSD/OS, Linux, OSF.

Fast:

In typical use it‘s about as fast as the best full-featured servers (Apache, NCSA, Netscape). Under extreme load it‘s much faster.

Secure:

It goes to great lengths to protect the web server machine against attacks and breakins from other sites.

It also has one extremely useful feature (URL-traffic-based throttling) that no other server currently has. Plus, it supports IPv6 out of the box, no patching required.

（2）IM WebServer

Jabber

Jabber is InstantMessaging(IM) server written in pure C language,which is the origin of XMPP. It is based on XMPP(Extensible Messaging and Presence Protocol) expressed in XML.With Jabber/XMPP, differences between the IM are overcomed. It allows you to communicate between MSN,Yahoo, and etc.

Instant messaging between the Google Talk servers and its clients uses an open protocol, XMPP, allowing users of other XMPP/Jabber clients to communicate with Google Talk users. That is any client that supports Jabber/XMPP can connect to the Google Talk service.Refer to Google Talk and MSN via Jabber together in iChat.

Nginx

nginx [engine x] is a HTTP and reverse proxy server, as well as a mail proxy server written by Igor Sysoev. It has been running for more than five years on many heavily loaded Russian sites including Rambler (RamblerMedia.com). According to Netcraft nginx served or proxied 4.70% busiest sites in April 2010. Here are some of success stories: FastMail.FM, Wordpress.com.

The sources are licensed under 2-clause BSD-like license.

Basic HTTP features：
l  Serving static and index files, and autoindexing; open file descriptor cache;

l  Accelerated reverse proxying with caching; simple load balancing and fault tolerance;

l  Accelerated support with caching of remote FastCGI servers; simple load balancing and fault tolerance;

l  Modular architecture. Filters include gzipping, byte ranges, chunked responses, XSLT, SSI, and image resizing filter. Multiple SSI inclusions within a single page can be processed in parallel if they are handled by FastCGI or proxied servers.

l  SSL and TLS SNI support.
