Cynosure has two developed and sold two main products - DQNET and NETSNIFF. At the present time, we do not actively market either product. However, we continue to provide support to those who have purchased these products.
There are two communications products -
DQBRIDGE and
DQSTERM - that developed out of the
main DQNET product. These products continue to be sold and supported.
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. This product will not be ported to QNX6 unless existing customers indicate a requirement for a QNX6 version.

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 packet-level traffic on their Ethernet LAN (local area network). Packets can be displayed 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, UDP, ICMP, 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.
