If possible I would recommend to check a library called libpcap if it suits for your application. It is a generic library which works on many operating systems and is used by a well known tool program tcpdump. This library captures packets on the Ethernet level very nicely and gives them to an user program to analyze/process them. I have used in one special networking project very successfully. You can find some libpcap related link on the following page: http://www.epanorama.net/cgi-bin/search.cgi?keyword=libpcap -- Tomi Engdahl (http://www.iki.fi/then/) Take a look at my electronics web links and documents at http://www.epanorama.net/
