NAME

tcpcapinfo − Pcap file dissector for debugging broken pcap files

SYNOPSIS

tcpcapinfo [−flags] [−flag [value]] [−−option-name[[=| ]value]] <pcap_file(s)>

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.

DESCRIPTION

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.
