TCP/IP

Learn to use the implementation of asynchronous Win32 sockets without the use of MFC.

If you are unable to find a free Modbus Slave simulator, here is one.

Discover how to intercept network traffic (IP packets) by putting a socket in promiscuous mode.

Learn how to use a mailslot to broadcast information over a network.

Most available web filters work inline, meaning that all outgoing and incoming packets are passed through a filter driver. This approach along with its own benefits has a big flaw; the filtering process affects data transfer throughput. Learn about an experimental remedy to this issue by putting the filter engine in sniffer mode. This way, the filtering process and data transfer act independently.

A clone of the Win95/98/ME utility for checking and controlling IP addresses.

Learn about the TCP Half Open Scanning or TCP SYN scanning technique.

This program watches for DNS requests, lists them, and allows you to save them to block certain sites.

TCP Ping is necessary when measuring server functionality from different IP networks (mirror sites).

Updated to version 4. This library enumarates the TCP/IP protocol, and allows the user to create custom TCP/IP headers, this allows IP spoofing and more.

Networked Simulated Plants (NSP) is a frame program that connects a Modbus/TCP server with a automation simulation. It delivers Ethernet I/O to programmable logic controllers (PLCs).

Learn how to develop a simple but effective port scanner for Win32, using a self written socket classes (not the CSocket which comes with MFC) and a small framework based on the CPropertySheet/CPropertyPage classes.

Presents a fantastic custom packet monitoring utility for Windows 2000

Detecting and terminating aborted TCP/IP connections
