Scapy - Python Scripting with Scapy.

Scapy is a powerful and flexible Python-based interactive packet manipulation tool and network protocol scanner. It allows you to craft, send, receive, and manipulate network packets at a low level. Scapy is often used for network analysis, testing, and penetration testing, as it provides the capability to create custom packets and interact with network protocols in a way that is not easily achievable with standard networking libraries.


Key features of Scapy include:


1. **Packet Creation and Manipulation:** Scapy allows you to create and customize network packets from scratch. You can define various packet fields, headers, and payloads to craft packets tailored for specific purposes.


2. **Packet Sending and Receiving:** Scapy enables you to send and receive packets over a network interface. You can send crafted packets to a target and capture packets from the network, which is useful for analyzing network traffic.


3. **Packet Sniffing:** Scapy can capture and display live network traffic, making it useful for analyzing network communication and identifying potential security vulnerabilities.


4. **Protocol Support:** Scapy supports a wide range of network protocols and allows you to work with both common and custom protocols. This versatility makes it a valuable tool for network research and analysis.


5. **Network Exploration and Security Testing:** Scapy can be used for security testing and penetration testing. It can help identify network weaknesses and vulnerabilities by sending custom packets and observing the responses.


6. **Interactive Shell:** Scapy provides an interactive shell that allows you to experiment with packet creation, manipulation, and network interaction in real-time.


7. **Scripting and Automation:** Scapy can be scripted to automate various network-related tasks, such as network discovery, testing, and troubleshooting.


While Scapy is a powerful tool, it's important to note that it operates at a low level and requires a good understanding of networking protocols to use effectively. It's commonly used by network administrators, security professionals, and researchers who need granular control over network interactions and packet analysis.

This lab aims to learn how we use Scapy and python to programme the network monitor tools (manipulating, sending, receiving and sniffing packets

Fixing Unix/Linux/POSIX Filenames

Traditionally, Unix/Linux/POSIX filenames can be almost any sequence of bytes, and their meaning is unassigned. The only real rules are that "/" is always the directory separator, and that filenames can't contain byte 0 (because this is the terminator). Although this is flexible, this creates many unnecessary problems. In particular, this lack of limitations makes it unnecessarily difficult to write correct programs (enabling many security flaws), makes it impossible to consistently and accurately display filenames, causes portability problems, and confuses users. more ....

Multi-Boot Disk for Machines With AMD Opteron Processors

This article presents step-by-step procedures for loading the Solaris 10 OS on x86 platforms, and one or two 64-bit Linux operating systems, on machines based on 64-bit AMD Opteron processors. Installations were done on generic Opteron-based workstations and confirmed on a Sun Fire V20z server and Sun Java Workstation W1100z and W2100z workstations.

Debugging Perl

The standard Perl distribution comes with a debugger, although it's really just another Perl program, perl5db.pl. Since it is just a program, I can use it as the basis for writing my own debuggers to suit my needs, or I can use the interface perl5db.pl provides to configure its actions. That's just the beginning, though. read more...
