Scapy

A Python program that enables users to send, sniff, dissect, and forge network packets, allowing the construction of tools for network probing, scanning, and attacking.

Packet forging tool

A tool that forges packets and sends them.

Sniffing tool

A tool that captures packets and possibly dissects them.

Testing tool

A tool that performs unitary tests, usually answering yes/no questions like ping.

Scanning tool

A tool that conducts multiple unitary tests with varying parameters.

Fingerprinting tool

A tool that performs predefined eclectic unitary tests to distinguish a peer.

Attacking tool

A tool that utilizes unexpected values in a protocol.

Basic Commands

Fundamental commands in Scapy for packet crafting and manipulation.

Layer stacking

Building packets in Scapy layer by layer, allowing manipulation of each layer or packet.

Interactive Scapy shell

An interactive shell in Scapy that allows users to craft packets and explore network protocols.

Visualization tools

Tools that enable interfacing with visualization tools like PCAP and Wireshark.

Documentation

Detailed information about Scapy available at http://www.secdev.org/projects/scapy/doc/.

Packet Crafting

The art of manually generating packets to test network devices.

Scapy

A powerful interactive packet manipulation tool for packet crafting, sniffing, scanning, and more.

IP Packet

A unit of data that is transmitted over an IP network, containing source and destination IP addresses.

Ethernet

A widely used networking technology for connecting devices in a local area network (LAN).

TCP

Transmission Control Protocol, a core protocol of the Internet protocol suite that facilitates reliable communication.

UDP

User Datagram Protocol, a connectionless protocol that offers minimal overhead for data transmission.

ICMP

Internet Control Message Protocol, used for diagnostic and control purposes in IP networks.

Packet Assembly

The process of constructing packets by adding necessary headers and data.

Packet Editing

Modifying the content or headers of packets to suit specific requirements.

Packet Re-Play

Sending previously captured packets back onto the network for various purposes.

Packet Decoding

Analyzing the contents of packets to understand their structure and data.

Packet Sniffing

Capturing and analyzing network traffic to inspect packets for various purposes.

Packet Exporting

Saving captured packets in different formats for future analysis or sharing.

Packet Importing

Loading packets from external sources like PCAP files for further examination.
