    en.wikipedia.org/wiki/Wireshark

    Wireshark is a free and open-source packet analyzer. It is used for network troubleshooting, analysis, software and communications protocol development, and education. Originally named Ethereal , the project was renamed Wireshark in May 2006 due to trademark issues.

  3. Packet analyzer - Wikipedia

    en.wikipedia.org/wiki/Packet_analyzer

    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.

  4. pcap - Wikipedia

    en.wikipedia.org/wiki/Pcap

    A capture file saved in the format that libpcap, WinPcap, and Npcap use can be read by applications that understand that format, such as tcpdump, Wireshark, CA NetMaster, or Microsoft Network Monitor 3.x. The file format is described by Internet-Draft draft-ietf-opsawg-pcap; [5] the current editors' version of the draft is also available. [6]

    en.wikipedia.org/wiki/Packet_crafting

    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. Depending on the packets sent, a desired ...

    Free and open-source software portal; Tcptrace, a tool for analyzing the logs produced by tcpdump; EtherApe, a network mapping tool that relies on sniffing traffic; Ngrep, a tool that can match regular expressions within the network packet payloads; netsniff-ng, a free Linux networking toolkit; Wireshark, a GUI based alternative to tcpdump

  7. Scapy - Wikipedia

    en.wikipedia.org/wiki/Scapy

    It can forge or decode packets, send them on the wire, capture them, and match requests and replies. It can also handle tasks like scanning, tracerouting, probing, unit tests, attacks, and network discovery. Scapy provides a Python interface into libpcap or native raw sockets, in a similar way to that in which Wireshark provides a view and ...

  8. Network packet - Wikipedia

    en.wikipedia.org/wiki/Network_packet

    Communications protocols use various conventions for distinguishing the elements of a packet and for formatting the user data. For example, in Point-to-Point Protocol, the packet is formatted in 8-bit bytes, and special characters are used to delimit elements. Other protocols, like Ethernet, establish the start of the header and data elements ...

  9. Tcptrace - Wikipedia

    en.wikipedia.org/wiki/Tcptrace

    [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 ...
