Sniff(filter='port 80', prn=process_packet, store=False)Īs you may notice, we specified port 80 here, that is because HTTP's standard port is 80, so we're already filtering out packets that we don't need. Sniff(filter='port 80', prn=process_packet, iface=iface, store=False) Sniff 80 port packets with `iface`, if None (default), then the

Let's define the function that handles sniffing: def sniff_packets(iface=None): Let's import the necessary modules: from scapy.all import *įrom import HTTPRequest # import HTTP packet We need colorama here just for changing text color in the terminal. If you have problems installing Scapy, check these tutorials: Let's install the requirements for this tutorial: pip3 install scapy colorama In Scapy 2.4.3+, HTTP packets are supported by default. Once an HTTP request is captured, we extract some information from the packet and print them out.

The basic idea behind the recipe we will see in this tutorial is that we keep sniffing packets. There are other tools to capture traffic, such as tcpdump or Wireshark, but in this guide, we'll use the Scapy library in Python to sniff packets. In this tutorial, you will see how you can sniff HTTP packets in the network using Scapy in Python. Monitoring the network always seems to be a useful task for network security engineers, as it enables them to see what is happening in the network, see and control malicious traffic, etc.
