(Ethereal is an open source network analysis system, and it is also the best open source network protocol analyzer, supporting Linux and Windows methods. Ethereal was first developed by GeraldCombs, and later protected by a loosely organized Etheral team. The powerful protocol analysis function it now provides is completely comparable to the US commercial network analysis system. Since the earliest version 0.2 was released in 1998, many volunteers have added new protocol parsers to Ethereal. Now Ethereal now supports more than 500 A protocol analysis. It is hard to imagine that the code developed by so many people can be well integrated into the system; and it is very simple to join a new protocol parser in the system, and a rookie who does not understand the structure of the system can also customize the system based on the reserved interface. protocol development. This is all thanks to the good design structure of Ehereal. In fact, due to the variety of various protocols on the network, various new protocols emerge one after another. A good protocol analyzer must have good extensibility and structure. Only in this way can we adapt to the needs of network development and continuously add new protocol parsers. ===================================================== =================== If you want to know more about Ethereal, please download this book after EtherealPacketSniffing! ! !
