This is the time the sensor MAC received the packet. It is a 4-byte unsigned int. TAG_CONTENTION_FREE = 15 (0x0F) This is used to tell if the packet was sent in a contention free period. It is a 1-byte unsigned byte. TAG_DECRYPTED = 16 (0x10) This is used to tell if the packet was decrypted. It is a 1-byte unsigned byte. TAG_FCS_ERROR = 17 (0x11)
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 ...
Wireshark is a data capturing program that "understands" the structure (encapsulation) of different networking protocols. It can parse and display the fields, along with their meanings as specified by different networking protocols. Wireshark uses pcap to capture packets, so it can only capture packets on the types of networks that pcap supports.
snoop, a command line packet analyzer included with Solaris; wireshark, a network packet analyzer; dsniff, a packet sniffer and set of traffic analysis tools; netsniff-ng, a free Linux networking toolkit; ngrep, a tool that can match regular expressions within the network packet payloads; etherape, a network mapping tool that relies on sniffing ...

ngrep (network grep) is a network packet analyzer written by Jordan Ritter.It has a command-line interface, and relies upon the pcap library and the GNU regex library.. ngrep supports Berkeley Packet Filter logic to select network sources or destinations or protocols, and also allows matching patterns or regular expressions in the data payload of packets using GNU grep syntax, showing packet ...
Adapters are available to aggregate packets from multiple network segments and wireless channels at the same time. The most notable decoders are the protospecs and decoder files, which are interpreted text files that can be extended by the user to enhance the display and analysis of existing protocols, and add knowledge of completely new ...
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]
