This tutorial series for newcomers explains TCP timeout retransmission, window management, and congestion control, combining theory with practical experiments using tcpdump, netstat, iptables, and Scapy, and demonstrates how Linux kernel parameters affect retransmission behavior and performance.
This tutorial explains how to perform host discovery and various port‑scanning techniques—including TCP SYN, ACK, UDP, ARP, and ICMP pings—as well as service discovery scans (SYN, FIN, NULL, Xmas, UDP) and traceroute methods using Scapy, complete with code examples and interpretation of results.
This guide demonstrates how to use Python's Scapy library to extract IP addresses from PCAP files, sniff usernames and passwords from mail traffic, discover live hosts via SYN packets, launch MAC address table flooding attacks, and conduct ARP spoofing for man‑in‑the‑middle attacks, providing complete code examples.
This tutorial shows how to use Python's Scapy library to craft and send ARP requests for network discovery, perform ARP spoofing attacks, and implement TCP SYN port scanning by interpreting packet flags, providing complete code examples and practical security insights.
This guide explains how to use Scapy for host discovery (TCP SYN/ACK, UDP, ARP, ICMP pings), various port‑scanning techniques (SYN, FIN, NULL, Xmas, UDP) and traceroute methods (ICMP, TCP, DNS), providing complete code examples and practical insights.
This guide introduces Scapy, a powerful interactive Python packet manipulation tool, covering installation, basic usage, packet creation, sending and receiving functions, layer inspection, packet export formats, sniffing, and advanced features such as sprintf and custom packet handlers, enabling network testing, analysis, and security tasks.
This guide reviews the most frequent TCP/IP attacks—including IP spoofing, SYN flooding, UDP flooding, TCP reset hijacking, man‑in‑the‑middle, and DDoS—explains their underlying protocols, demonstrates practical exploitation with Python/Scapy and Netcat, and outlines mitigation techniques and cryptographic fundamentals.
This article introduces Python's Scapy library, explains what network packets are, lists common Scapy commands, demonstrates packet sniffing, crafting, sending, receiving, SYN scanning, serialization, and conversion techniques, and provides practical code examples for each operation.
Learn to uncover concealed Wi‑Fi networks by capturing router signals with a wireless adapter, using Ubuntu’s airodump-ng and Python’s Scapy library to monitor packets, identify hidden SSIDs, and display them when a client connects, complete with step‑by‑step setup and screenshots.
Learn how to create a practical employee smart‑check‑in tool with just 12 lines of Python code by capturing mobile MAC addresses via a USB Wi‑Fi adapter, using scapy and pandas on Ubuntu, and automatically logging attendance without expensive hardware.
This guide shows how to use Python's scapy library to send ARP broadcast packets, collect MAC addresses of devices on a hotel Wi‑Fi network, query their manufacturers, and identify potential hidden cameras, providing a practical method for ensuring hotel security.
