tcpdump is a data-network packet analyzer computer program that runs under a command line interface. ... tcpdump uses the libpcap library to capture packets.
[1] [2] [3] It accepts as input files produced by packet-capture programs, including tcpdump, Wireshark, and snoop. tcptrace can produce several different types of output containing information on each connection seen, such as elapsed time, bytes and segments sent and received, retransmissions, round trip times, window advertisements, and ...

libpcap was originally developed by the tcpdump developers in the Network Research Group at Lawrence Berkeley Laboratory.The low-level packet capture, capture file reading, and capture file writing code of tcpdump was extracted and made into a library, with which tcpdump was linked. [8]
Packet capture is the process of intercepting and logging traffic. As data streams flow across the network, the analyzer captures each packet and, if needed, decodes the packet's raw data, showing the values of various fields in the packet, and analyzes its content according to the appropriate RFC or other specifications.
In 2003, the OmniEngine Distributed Capture Engine was released as software, and as a hardware network recorder appliance. In the early morning of July 15, 2002, WildPackets' building in Walnut Creek, California burnt to the ground including everything in it. However, no one was hurt and the employees regrouped at a new location and the company ...
Free and open-source software portal; Bit-Twist is a powerful libpcap-based Ethernet packet generator and packet capture editor, written in POSIX-compliant C, designed to complement tcpdump by replaying captured traffic from pcap files onto live networks.
Packet Decoding is the capture and analysis of the network traffic generated during Packet Play. In order to determine the targeted network's response to the scenario created by Packet Play, the response must be captured by a packet analyzer and decoded according to the appropriate specifications.
