Libnet is a high-level API (toolkit) allowing the application programmer to construct and inject network packets.
It provides a portable and simplified interface for low-level network packet shaping, handling and injection.
Libnet hides much of the tedium of packet creation from the application programmer such as multiplexing, buffer management, arcane packet header information, byte-ordering, OS-dependent issues, and much more.
Libnet features portable packet creation interfaces at the IP layer and link layer, as well as a host of supplementary and complementary functionality.
Using libnet, quick and simple packet assembly applications can be whipped up with little effort. With a bit more time, more complex programs can be written.
