<![CDATA[Analyzing computer networks is an activity usually conducted by people working in the world of information technology especially in the field of computer networks. Often, when analyzing a computer network, need to generate network traffic the computer that can be determined freely. Network traffic in the form of blocks of bytes of a well-defined structure, called packets. To do so can only be made possible with the tools that one of his form in the form of software that can build a packet (packet generator) to then be sent to the network. In building the computer network packets needed a programming library that handles the packaging details, his name libnet. Libnet latest version (libnet-1.1) has advantages over its predecessor is in accordance with the concept of a layer of TCP / IP. With the latest version of libnet, methods build the same package with the concept of wrapping the layer of TCP / IP, the higher layer is wrapped by a lower layer. So that can be generated a packet generator software principles of computer networks that works with the concept of a layer of TCP / IP. And because the graphics-based, it can be possible to be made more flexible in handling packages. In addition, because using the frame-work of both Qt and libnet-free operating system platform, the development is not closed only on Linux-based operating system, but also other operating systems like Windows family of operating systems and Mac OS. Keywords: Generator, package, TCP/IP, libnet, Qt]]>
