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.
This package contains an old and deprecated version of libnet. You need it
only if the software you are using hasn't been updated to work with the newer
version and the newer API.
