    if you are talking about capturing packets by
    writing a program then you could use libpcap.a
    that provides an abstraction for the underlying
    bpf.

    man pcap would be a good help.

    sending custom packets can be done using raw sockets
    (SOCK_RAW).

    you can use IP_HDRINCL for including your custom
    ip header
