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 (Traceroute and ping were easily rewritten using libnet and <a href="www.tcpdump.org">libpcap</a>). <hr size="1"><address style="text-align: right;"><small>Generated on Tue Jun 9 16:16:39 2009 for libnet by <a href="http://www.doxygen.org/index.html"> <img src="doxygen.png" alt="doxygen" align="middle" border="0"></a> 1.5.3 </small></address> </body> </html>
