CodeAlpha_Network_Sniffer

This is a network sniffer in Python that captures and analyzes network traffic. It will help you understand how data flows on a network and how network packets are structured. This example captures and prints basic packet information.

Steps :

1) Imports

We import necessary components from scapy.

2) Packet Callback Function

The packet_callback function processes each captured packet and prints its details if it has IP, TCP, or UDP layers.

3) Start Sniffing Function

The start_sniffing function initiates packet sniffing on the specified network interface and captures a given number of packets.

4) Configuration

Set the network interface (interface) and the number of packets to capture (packet_count).

5) Start Sniffing

Call the start_sniffing function to start capturing packets.

6) Save Packets

Optionally, the captured packets are saved to a file named captured_packets.pcap.

Summary

The network sniffer script using scapy is a straightforward yet powerful tool for capturing and analyzing network traffic, making it ideal for network troubleshooting, security monitoring, and educational purposes in a Linux environment.
