This enables the creation of tools for probing, scanning, or attacking a network.<\/p><p>It is a powerful interactive packet manipulation program. It is used to forge or decode packets of a wide variety of protocols, send them, capture them, associate requests and responses, and much more.<\/p><p>Common tasks like scanning, tracerouting, probing, unit testing, attacking, or network discovery can be accomplished with ease. This tool can replace hping, arpspoof, arp-sk, arping, pof, and some parts of Nmap, tcpdump, and tshark.<\/p><p>Furthermore, Scapy can be used for specific tasks that most tools do not support. This includes sending invalid frames, injecting 802.11 frames, combining techniques like VLAN hopping and <strong>ARP cache poisoning.<\/strong><\/p><p>In essence, Scapy&#8217;s two main functionalities are sending packets and receiving responses. After defining a packet set, the tool sends them, receives responses, matches queries with responses, and returns a list of query\/response packet pairs and a list of unmatched packets.<\/p><p>The advantage over Nmap or hping is that a response is not reduced to &#8220;open,&#8221; &#8220;closed,&#8221; or &#8220;filtered.&#8221; It includes the complete packet.<\/p><p>Higher-level functions can be added, such as tracerouting and obtaining the initial TTL of the request and the source IP of the response as the result. Another example is a function that pings an entire network and provides a list of responding machines, or a function that performs a port scan to generate a LaTeX report.<\/p><p><strong>Scapy can be used interactively through its command-line interface (CLI<\/strong>) or as a library by importing it into Python programs. It can be run on Linux, macOS, or Windows.<\/p><p>Even though it is a tool without a graphical interface, it can be integrated with other visualization programs like Wireshark, GnuPlot, Graphviz, or VPython.<\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-10245131 elementor-widget elementor-widget-image\" data-id=\"10245131\" data-element_type=\"widget\" data-widget_type=\"image.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t<style>\/*! elementor - v3.15.0 - 02-08-2023 *\/\n.elementor-widget-image{text-align:center}.elementor-widget-image a{display:inline-block}.elementor-widget-image a img[src$=\".svg\"]{width:48px}.elementor-widget-image img{vertical-align:middle;display:inline-block}<\/style>\t\t\t\t\t\t\t\t\t<figure class=\"wp-caption\">\n\t\t\t\t\t\t\t\t\t\t<img decoding=\"async\" width=\"749\" height=\"446\" src=\"https:\/\/datascientest.com\/en\/files\/2023\/09\/scapy1.jpg\" class=\"attachment-full size-full wp-image-171424\" alt=\"\" srcset=\"https:\/\/datascientest.com\/en\/files\/2023\/09\/scapy1.jpg 749w, https:\/\/datascientest.com\/en\/files\/2023\/09\/scapy1-300x179.jpg 300w\" sizes=\"(max-width: 749px) 100vw, 749px\" \/>\t\t\t\t\t\t\t\t\t\t\t<figcaption class=\"widget-image-caption wp-caption-text\"><\/figcaption>\n\t\t\t\t\t\t\t\t\t\t<\/figure>\n\t\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-192b2eba elementor-align-center button-principale elementor-widget elementor-widget-button\" data-id=\"192b2eba\" data-element_type=\"widget\" data-widget_type=\"button.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t<div class=\"elementor-button-wrapper\">\n\t\t\t<a class=\"elementor-button elementor-button-link elementor-size-sm elementor-animation-grow\" href=\"https:\/\/datascientest.com\/en\/data-courses\">\n\t\t\t\t\t\t<span class=\"elementor-button-content-wrapper\">\n\t\t\t\t\t\t<span class=\"elementor-button-text\">Python Training<\/span>\n\t\t<\/span>\n\t\t\t\t\t<\/a>\n\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t<div class=\"elementor-element elementor-element-7e656ae6 e-flex e-con-boxed e-con\" data-id=\"7e656ae6\" data-element_type=\"container\" data-settings=\"{&quot;content_width&quot;:&quot;boxed&quot;}\">\n\t\t\t\t\t<div class=\"e-con-inner\">\n\t\t\t\t<div class=\"elementor-element elementor-element-3d1cf328 elementor-widget elementor-widget-heading\" data-id=\"3d1cf328\" data-element_type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t<h3 class=\"elementor-heading-title elementor-size-default\">What are the main shortcomings of networking tools?<\/h3>\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-40d6c9f6 elementor-widget elementor-widget-text-editor\" data-id=\"40d6c9f6\" data-element_type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t<p>To understand the advantages of Scapy, it is simplest to list the main problems with most networking tools. These different programs do not allow you to build something the author did not imagine. They are designed for a specific purpose and cannot deviate from it.<\/p><p>For example, an ARP cache poisoning tool cannot use double encapsulation 802.1q. Therefore, it is usually necessary to create a new program for each new requirement.<\/p><p>Furthermore, many tools are limited to a paradigm of being executed from a system interface shell. This results in complex syntax to describe a packet. The chosen solution uses a higher and less powerful description in the form of scenarios imagined by the tool&#8217;s creator.<\/p><p>In addition, these tools often confuse decoding and interpretation. While machines excel at decoding, they are not able to interpret. This task is reserved for humans.<\/p><p>Some programs try to mimic this behavior, for example, by saying &#8220;this port is open&#8221; instead of &#8220;I received a SYN-ACK.&#8221; However, they frequently make mistakes.<\/p><p>Such assistance can be invaluable for beginners, but experienced users know that they will spend a lot of time trying to deduce what actually happened from the program&#8217;s interpretation.<\/p><p>A significant amount of information is lost along the way. Often, it is necessary to use tcpdump -xX to decode and interpret everything that escaped the program.<\/p><p>Even programs that only decode do not provide all the information they received. They only offer the network view that their creator deems sufficient. Therefore, it is incomplete.<\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t<div class=\"elementor-element elementor-element-1cc23bdf e-flex e-con-boxed e-con\" data-id=\"1cc23bdf\" data-element_type=\"container\" data-settings=\"{&quot;content_width&quot;:&quot;boxed&quot;}\">\n\t\t\t\t\t<div class=\"e-con-inner\">\n\t\t\t\t<div class=\"elementor-element elementor-element-2782441a elementor-widget elementor-widget-heading\" data-id=\"2782441a\" data-element_type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t<h3 class=\"elementor-heading-title elementor-size-default\">Writing network tools in 2 lines of Python with ScaPy<\/h3>\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-646ba053 elementor-widget elementor-widget-text-editor\" data-id=\"646ba053\" data-element_type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t<p>On the other hand, Scapy attempts to overcome these various weaknesses. It allows you to build any packets you want and adopts a flexible model that avoids arbitrary limits. Users can place any value in a field and assemble them as they see fit.<\/p><p>Regarding packet description, Scapy offers a dedicated language known as Domain Specific Language (DSL), which allows for powerful and rapid descriptions for any type.<\/p><p>The use of Python syntax and a Python interpreter for this DSL brings multiple benefits. There is no need to write a separate interpreter, users do not have to learn an additional language, and they benefit from a complete, concise, and powerful language.<\/p><p>It is possible to describe a packet or a set of packets as stacked layers on top of each other. The fields of each layer have useful default values that can be overridden. Users are not obliged to use predefined methods or templates.<\/p><p>This eliminates the need to write a new tool every time a different scenario is required. Instead of using about sixty lines to describe a packet in C, it only takes one line with Scapy and another line to print the result. Thus, 90% of the lines in network probing tools can be rewritten in just two lines.<\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-95794f0 elementor-widget elementor-widget-image\" data-id=\"95794f0\" data-element_type=\"widget\" data-widget_type=\"image.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t\t\t\t<figure class=\"wp-caption\">\n\t\t\t\t\t\t\t\t\t\t<img decoding=\"async\" width=\"712\" height=\"440\" src=\"https:\/\/datascientest.com\/en\/files\/2023\/09\/scapy2.jpg\" class=\"attachment-full size-full wp-image-171425\" alt=\"\" srcset=\"https:\/\/datascientest.com\/en\/files\/2023\/09\/scapy2.jpg 712w, https:\/\/datascientest.com\/en\/files\/2023\/09\/scapy2-300x185.jpg 300w\" sizes=\"(max-width: 712px) 100vw, 712px\" \/>\t\t\t\t\t\t\t\t\t\t\t<figcaption class=\"widget-image-caption wp-caption-text\"><\/figcaption>\n\t\t\t\t\t\t\t\t\t\t<\/figure>\n\t\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-418b1d8a elementor-align-center button-principale elementor-widget elementor-widget-button\" data-id=\"418b1d8a\" data-element_type=\"widget\" data-widget_type=\"button.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t<div class=\"elementor-button-wrapper\">\n\t\t\t<a class=\"elementor-button elementor-button-link elementor-size-sm elementor-animation-grow\" href=\"https:\/\/datascientest.com\/en\/data-courses\">\n\t\t\t\t\t\t<span class=\"elementor-button-content-wrapper\">\n\t\t\t\t\t\t<span class=\"elementor-button-text\">Learn to use Scapy<\/span>\n\t\t<\/span>\n\t\t\t\t\t<\/a>\n\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t<div class=\"elementor-element elementor-element-656b6a3b e-flex e-con-boxed e-con\" data-id=\"656b6a3b\" data-element_type=\"container\" data-settings=\"{&quot;content_width&quot;:&quot;boxed&quot;}\">\n\t\t\t\t\t<div class=\"e-con-inner\">\n\t\t\t\t<div class=\"elementor-element elementor-element-4e06c478 elementor-widget elementor-widget-heading\" data-id=\"4e06c478\" data-element_type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t<h3 class=\"elementor-heading-title elementor-size-default\">A single survey for multiple interpretations<\/h3>\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-3bcd877e elementor-widget elementor-widget-text-editor\" data-id=\"3bcd877e\" data-element_type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t<p>During network probing, many stimuli are sent, and only a few of them receive a response.

However, it can also mean that there was no host to forward the packet to. Tool interpretation of results can therefore do more harm than good by introducing biases into the results.
