What does scapy ether do?

It is used for interacting with the packets on the network. It has several functionalities through which we can easily forge and manipulate the packet. Through scapy module we can create different network tools like ARP Spoofer, Network Scanner, packet dumpers etc.

What is scapy tool?

Scapy is a packet manipulation tool for computer networks, originally written in Python by Philippe Biondi. 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.

What does sniff do in Scapy?

sniff has an argument prn that allows you to pass a function that executes with each packet sniffed. The intended purpose of this function is to control how the packet prints out in the console allowing you to replace the default packet printing display with a format of your choice.

What is the difference between send and Sendp in Scapy?

The send() function will send packets at layer 3. That is to say, it will handle routing and layer 2 for you. The sendp() function will work at layer 2. It’s up to you to choose the right interface and the right link layer protocol.

What is Scapy ARP?

This would enable the network packets sent by the target, to pass from our machine to the network gateway making the ARP spoof successful. To design a python script to create an ARP spoofer, we require the Scapy module. Scapy is a very powerful packet manipulation tool and library which is completely written in python.

What can you do with Scapy packet sniffer?

Scapy also has the capability to store the sniffed packets in a pcap file. Using scapy, we will be able to handle tasks like trace routing, probing, scanning, unit tests, and network discovery with ease. All of these properties make scapy useful for network-based attacks.

How to use Scapy sniff function in Java?

We can do that very simply using the Scapy sniff () function and the filter argument like this:

How does the PRN argument in Scapy work?

Basically, what the prn argument lets us do is replace the default Scapy printout of the packet summary and run our own function to determine how Scapy prints out. That’s really cool! It works by passing the packet object to the defined function, in this case arp_display (), each time a packet is sniffed that matches the specified filter.
