Cynosure has two developed and sold two products, although we
currently do not actively market either product.
The DQNet product was developed in the early 1990s to help people connect networks of QNX2 (and later QNX4) computers with MS-Windows computers. Given the availability of the Internet protocols (TCP/IP) for current MS-Windows platforms and QNX4/QNX6, the DQNet products are essentially obsolete.
We do support our current customers using QNX2 and QNX4 environments. In fact, DQNet has allowed one of our clients to upgrade some of their products to QNX4, while remaining compatible with their existing QNX2 products still in the field. We have begun discussions with this client about developing a QNX6 version; no decisions have been made yet.

DQNet Overview
The Nethound II product was first demonstrated at the Toronto QNX User's Conference in 1996. This product allows a user to sit at a QNX4 station, and watch the traffic on the Ethernet. Packets can be shown in real time, or captured and displayed later at human speeds. Packets can be shown "raw" (without any interpretation) or with the underlying protocol fields broken out for display (IP, TCP, HTTP, Telnet, FTP, etc.).
Currently, there are a variety of equivalent products available on the Internet for free. Many of these run on an MS-Windows operating system. Some are quite sophisticated.
We have used Ethereal when we need to monitor an Ethernet using a Windows computer. Let us know if you find one that you like better.
