These are commercial products. The SNMP Builder for C++ has two different packages, supporting Windows 2003/2000/XP operating systems:

• SNMP Builder for Microsoft VC++ v6 and .NET 2003, 2005.
• SNMP Builder for Borland C++ Builder v6 and Studio 2006.

Both SNMP Builder packages include:

• MIB Compiler.
• SNMP C++ Class Library v3.3 supporting SNMP v2c and v1.
• SNMP Sender and Tracer Utilities.
• Guide and Reference Manual.
• Examples.

The MIB Compiler with a friendly and flexible graphic user interface allows the quick and easy accomplishment of the MIB compilation process. A programmer can determine the correct order of MIBs to compile in a matter of seconds using powerful built-in error processing and file search facilities. The final step of the MIB compilation process is generation of C++ header files with MIB object definitions.
The MIB Compiler enables SNMP object references to use symbolic names. This makes programming easier and simplifies the software maintenance and modification process. New, efficient, easy to use and versatile methods have been added to make software development even easier and more pleasant. As with the SNMP Toolkit, the SNMP Builder comes with two very useful SNMP tools:

• An SNMP Sender and
• An SNMP Tracer.

These two GUI utilities provide a much more precise and flexible interface (comparing to MIB browser) assisting in debugging of SNMP software and also in studying how the existing SNMP software works in real life applications.
The Tracer utility replaces the need for a very expensive protocol analyzers. It can display both parsed SNMP message fields (SNMP message header, PDU fields and variable binding list details) and raw message data. The trace can be saved and printed. The utility can receive on standard SNMP ports: 161 and 162, and also on non-standard ports.
The Sender utility includes a graphic editor enabling the creation of SNMP request messages with precise control of message type, header fields and variable binding list. The utility can send the requests to a specified destination, displaying the details about sent requests and received replies. The sender can send the same request multiple times to a single destination, measuring network performance and the maximum number of requests an agent can process per second. These requests can be saved and then used later on during regression testing.
The detailed programming guide and reference manual in Adobe Acrobat format contains hyperlinks which simplify the quick reference look-up and serves as an on-line help. The extensive programming guide illustrates all the aspects, features and pitfalls of using class library objects, methods and properties to achieve maximum performance, reliability and flexibility of the software being developed.

SocketCC is a class library that encapsulates the existing Sockets API which is available on all Linux/UNIX environments and provides a simple solution to writing networked IP applications in these environments. As an advantage, the class structure supports both the TCP and UDP Protocols as well as development of IPv4 and IPv6 capable applications.

SocketCC was originally developed the personal needs while developing an IPv4/IPv6 Streaming Traffic Generator. At this stage an article about SocketCC was written and published in Dr. Dobbs Journal - read the article. The SocketCC library and associated documentation can be downloaded here.

RockSaw is a simple API for performing network I/O with raw sockets in Java. It has been deployed on thousands of computing nodes as part of internal custom enterprise applications. The current version of RockSaw compiles on Linux, Win32 with Cygwin/MinGW/Winsock or Visual C++, Solaris 8/9/10, FreeBSD 5.3, and Darwin. It should compile on other POSIX systems using the GNU tool chain. Configuration of the JNI build via autoconf may be added somewhere down the line. There just are not enough platform-specific cases in the native code to warrant it right now, but the GNU Makefile is accumulating if blocks.

The given Ping.java example program requires at least VServ TCP/IP version 0.7.x to compile because it uses the ICMPEchoPacket class. RockSaw is released under the Apache License 2.0.

The ADAPTIVE Communication Environment (ACE) is a freely available, open-source object-oriented framework that implements many core patterns for concurrent communication software. ACE provides a rich set of reusable C++ wrapper facades (pdf document) 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.

ACE continues to improve and its future is bright. ACE is supported commercially by multiple companies using an open-source business model. In addition, many members of the ACE development team are currently working on building The ACE ORB (TAO).

This is a GPL licensed C++ class socket 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 source code is released under the terms of the GNU GPL, but is also available under an alternative license.

The libraries examples include: SMTPProxy (smtp proxy / spam filter), PortProxy, ChatServer (A very simple chat server.), Small MUD, MudBase, ClientServer, HttpGet, DChat, WebServer, UDP, ICMP (chat program).

…Opensourcetesting.org aims to boost the profile of open source testing tools within the testing industry, principally by giving users easy access from one central location to the wide range of open source testing tools available.

These tools are free as in speech, not free as in beer. While you will not need to pay a vendor to use the tools, they still have a cost of ownership through evaluation, implementation, training and maintenance costs, the same as any software does. But with a handful of commercial vendors dominating the proprietary software testing tools market, make no mistake about it – these tools can make a real difference to your life as a testing professional…
