RawNetIo is a framework for doing raw ethernet IO for windows. With RawNetIo a user mode windows application can easily sniff the network traffic coming to an ethernet adapter and it can send raw ethernet frames to do interesting things such as network intrusion detection, building a user mode TCP firewall etc. RawNetIo is developed to make it easy for programmer to write networking tools for windows without worrying about Windows kernel mode programming and details of NDIS. For detailed information on using RawNetIo framework, take a look at file RawNet.chm by extracting both .chm and .chi files to a folder.

A sample application SnifFire is also developed using RawNetIo to illustrate its usage. Full source code of SnifFire is provided here.
