I recently found some time to code a little and I was interesting in doing a little packet sniffer just for for fun. :)
I am working with gcc and libpcap and i already read the tutorial in www.tcpdump.org. I also tried looking around dsniff source code, but that's a little ahead of me right now, I want to do more simple stuff just for learning purposes. I was looking for more tutorials about how to capture the TCP/UDP/IP packets in ethernet, more interested in the data layer itself. Google wasn't able to give me much of interest or I inserted the wrong question. Does anyone know any good books or other tutorials about capturing packets? Thanks, Nuno Branco
