DESCRIPTION

tcpcapinfo is a tool for decoding the structure of a pcap(3) file with a focus on finding broken pcap files and determining how two related pcap files might differ.

tcpcapinfo will first print out the pcap_file_header_t in human readable form followed by a per-packet summary including the pcap_pkthdr_t and simple checksum value of the packet.
