Freeware + source 06 May 2005


Easy access VCL components using same naming as Borland's ScktComp unit for HawkNL network library.

HawkNL is a free, open source, game oriented network API released under the GNU Library General Public License (LGPL). HawkNL (NL) is a fairly low level API, a wrapper over Berkeley/Unix Sockets and Winsock. But NL also provides other features including support for many OSs, groups of sockets, socket statistics, high accuracy timer, CRC functions, macros to read and write data to packets with endian conversion, and support for multiple network transports.

The JD Socket Components wrap the existing TServerSocket and TClientSocket in Delphi’s ScktComp unit. They work on a command/parameter approach, rather than a string parsing approach. The components take care of the parsing and provide simple commands. Also feature many other abilities, such as login authentication, cookie authentication, and property synchronizing.

NOTE: These components are in development stages, but are working. Notes and documentation are included in the source code to understand how they work.

Sample project code included.

Magenta Systems Internet Packet Monitoring Components v.1.3

By Magenta Systems Ltd.

Freeware + source 30 Sep 2013


Magenta Systems Internet Packet Monitoring Components are a set of Delphi components designed to capture and monitor internet packets using either raw sockets or the WinPcap device driver. Hardware permitting, ethernet packets may be captured and interpreted, and statistics maintained about the traffic. Uses of packet monitoring include totalling internet traffic by IP address and service, monitoring external or internal IP addresses and services accessed, network diagnostics, and many other applications. The component includes two demonstration applications, one that displays raw packets, the other that totals internet traffic. The components include various filters to reduce the number of packets that need to be processed, by allowing specific IP addresses to be ignored, LAN mask to ignore local traffic, and ignore non-IP traffic such as ARP.

The components capture packets using two different techniques, with differing benefits and features:

  • Raw sockets which are available with Windows 2000 and later. This uses WSocket from the Francois Piette Internet Component Suite. Major benefit is that no other software needs to be installed, but raw sockets don't seem to work fully with some network adaptors, and ignore non-IP protocols. Some adaptors may capture received packets, but ignore anything sent.
  • WinPcap (Windows Packet Library) device driver, needs to be installed (it installs two small DLLs and a driver), but captures all packets including non-IP. WinPcap may be downloaded from WinPCap site, and version 4.0.2 is included in this package. Note the Delphi WinPcap pcap.pas and packet32.pas modules were originally written by Lars Peter Christiansen, but have several bug fixes and many new features. In theory WinPcap will run on Windows 9x, but it's not been tested. Use of the latest WinPcap version 4.0.2 9th November 2007 is strongly recommended, but the component also supports older versions 3.1 5th August 2005 and 3.0 10 February 2003.

TML/SIDEX v.1.1.2

By wobe-systems GmbH.

CS 02 Jul 2014


TML/SIDEX provides out of the box functionality to implement fast and reliable TCP/IP communication.

After spending a lot of time thinking about application protocols and finding them not suitable for your problems and you desperately start thinking about using a TCP/IP socket, it might be a good idea to check if TML/SIDEX can help to save time.

If you want to send some data or just save it into a file think about XML. At the point you start writing your own type conversion code to translate the text nodes into something else, or you get into trouble with unicode, think about SIDEX.

  • calling remote functions in multiple interfaces
  • multithreaded and threadsafe processing
  • type safe data layer with variant support for lists, dictionaries and tables
  • single call multiple answer to monitor remote calls
  • synchronous and asynchronous calls
  • calling remote functions in multiple interfaces
  • point to multipoint events
  • multi platform dll with multiple language bindings
  • type safe XML based data format
The Source for the Delphi/C++ Builder components is included. Some dlls are required. The source for the dlls is NOT included.

TSocketStream v.0.1

By LOCK Soluciones.

Freeware + source 26 Feb 2005


TSocketStream is a easy to use non VCL class prepared to connect or listen connections via TCP/IP. It supports host name resolve via DNS (using the O.S. gethostbyname() call).

It is syncronous, but it also has this two methods: CanWrite for client sockets, and CanAccept for listening sockets, thus allowing non-blocking implementations without the need for non-blocking sockets.

The same class allows connecting to a remote host, or listening on any port and waiting por incoming connections. Examples for each case is included.

Tested in Delphi 5, not tested in other versions or in Free Pascal.

TUdpSocket v.0.95

By Frank Dekervel.

Freeware + source 13 Jul 1998


TudpSocket is a component for using UDP in your applications. It is as easy as Tsockets, but it has a different design because it is UDP. Therefore, you can't create connections or accept connections, you simply can bind the UDPsocket to a specific port, and send UDP data to another machine/port. You can also send broadcast messages, just send data to your subnet's broadcast address.
