Should be compatible with at least Delphi 2-7, experimental D2009/D2010 compatibility. Uses the Winsock unit for sockets. Remember to read the ReadMe file too.

This should finally be the last version. Read about changes from the website.

• TCP Client
• TCP Server
• Socks and HTTP proxy support.

Included two demo:

• Simple HTTP server what can work in HTTP and HTTP over SSL mode (HTTPS). SSL mode based on Windows SChannel provider and supports SSL 2.0, SSL 3.0 and TLS 1.0 protocols in any combinations.
• Simple Client/Server application used SSPI client authentication.

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 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.

Contains:

• TServerSocket - implement master socket that can listen for connections
• TClientSocket - implement client socket which can be connected to any other.

• Edit the code to suit your own personal needs.
• Turn the component into and object and drop the overhead with only a define statement.
• Put a listening socket into your application with only three lines of code.
• Fully customizable.
• Virtual methods for the TObject version and OnEvents for the component.

All classes are suitable for both Delphi and Kylix and are especially designed for ease of use.

Source: Included

• Package caches resolved IP Addresses for faster DNS lookups;
• Supports both TCP and UDP protocols;
• Listening mode will automatically accept incoming connections, create a new TSock component for the connected socket, and spawn a new thread of execution to handle concurrent blocking server connections;
• Support for blocking and non-blocking socket communications;
• Component can transfer blocks of data up to 4 gigabytes in length and more.

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.
