    Hello all you readers,
    For a student project, I'm going to develop a simple application which stay in the gateway and send TCP reset to live connections which matches to my criteria. The program should work in sniffer mode. I had some R&D around snort and pcap but want to know if anybody has experiences in this issue. please guide me.

    Cheer ya all.

    You better look for LIBNET library available at libnet.sourceforge.com.
    Also a good article in network programming forums may help you. some samples are also availble here:
    low level network security programming blogspot.
    Hope it helps.

    For a clue I'm looking for a working code such as snort but snort is really complicated. You know any simple application that performs all or parts of the subject?
