To get a feel for Scapy, let’s start by building a skeleton sniffer that sim- ply dissects and dumps the packets out. This technique can of course be applied to any protocol or to sim- ply suck in all traffic and store it in a PCAP file for analysis, which we will also demonstrate. Later, by coupling our sniffer with our Address Resolution Protocol (ARP) poisoning man-in-the-middle (MITM) attack, we can easily steal credentials from other machines on the network. We are going to build a very simple sniffer to cap- ture SMTP, POP3, and IMAP credentials. So let’s get to know Scapy’s interface for sniffing packets and dissecting their contents. You have already spent some time getting into the nuts and bolts of sniff- ing in Python.

Scapy Interface Stealing Email Credentials It can also handle tasks like scanning, tracerouting, probing, unit tests, attacks, and network discovery. It can forge or decode packets, send them on the wire, capture them, and match requests and replies. It depends on the goal you are trying to achieve but if you need to build a project the one it's features is sniffing IP packets then I recommend to use scapy for more stable scripts.Scapy is a packet manipulation tool for computer networks, originally written in Python by Philippe Biondi. You can do much more with scapy by reading it's documentation here:
#Scapy http sniffer code#
This code will print for you the source IP and the destination IP for every IP packet. Sniff(filter="ip", prn=lambda x:x.sprintf("")) This tutorial might help you understand the proccess of understanding a raw packet and splitting it to headers: The easy wayĪnother method to sniff IP packets very easily is to use the scapy module. This is and image of the format of the IP protocol with the sized in bits of every header. To read an IP packet you need to analyze the received packet in binary according to the IP protocol. Raw socket is a socket the sends and receives data in binary.īinary in python is represented in a string which looks like this \x00\xff. You can sniff all of the IP packets using a raw socket. I sent a new defect ticket to the Scapy developers:, hope they can do something with it.Īnyways, just thought I'd let y'all know. I installed the original version of PyPcap (from Google's site), and Scapy started working fine (I didn't try many things, but at least it didn't crash as soon as I started sniffing). It was this modified PyPcap that was causing the problem, apparently, since the example in the answer also caused a hang.

#Scapy http sniffer install#
(If anyone is interested, I'm running Windows Vista, which might affect things).Īfter reading the answer telling me to install PyPcap, I messed around with it a bit and found out that Scapy, which I had tried using, was telling me to install PyPcap as well, except that it's a modified version for it's use. I would assume that it's just a problem with how I installed it, except that many other people have told me that it doesn't work particularly well on Windows. I've heard from several places that the best module for this is a module called Scapy, unfortunately, it makes python.exe crash on my system. What is the best way to sniff network packets using Python?
