How to do it...

Following are the steps to create packets with the scapy module:

1. Create a new file called scapy-packet.py and open it in your editor.
2. As usual, import the scapy module and pprint for better readable printing:

from scapy.all import *
from pprint import pprint  

3. Packets are crafted by defining the packet headers for each protocol layer of TCP/IP and stacking them in the correct order. So, we can create the first layer of a TCP packet with the following:

ethernet = Ether()  

4. Then we can create the IP layer of the packet, as follows:

network = IP(dst='192.168.1.1/30')  

As it's the network layer, we have to pass the destination IP as the parameter. Scapy accepts different IP notations, as follows:

• • Plain dotted-quad notation: ...
