History and overall description

The BNT Net was developed incrementally to satisfy two needs:

  1. Home use by me, my wife and two kids for class preparation, research, school homework, games, multimedia, etc.
  2. Simulate a quasi-real life network environment in which I could test and learn a variety of operating systems, networking and application tools and techniques.

The BNT Net started, late in 1993, with two separated networks (grownups and kids) each with two machines, using 10base2 and Windows for Workgroups 3.1. The grownups were connected to the Net through a dial-up connection over a phone line sharing the same connection using Wingate as a proxy server.

The software was upgraded to Windows 95 during 1994 and 1995 (new machines were bought to accomodate the increasingly voracity of applications for CPU speed, memory and hard-drive space), one of the new machine was upgraded to NT Workstation 4.0. The grownups group was upgraded to a cable modem connection, while the kids group was connected through dial-up to the Net in 1997, but the two groups were maintained separated and using 10base2.

Finally, in 1998, the two networks were converted to one, using 10Base-T and an eight-port hub. Three new machines were bought (Windows 95, 98 and NT Workstation), the existing NT Workstation was upgraded, and NT Server software was installed on it. The latest addition to the BNT Net was the Linux Machine, and Sygate -- a Network Address Translator (NAT) and firewall software -- replaced Wingate, in January 1999.

Design decisions and characteristiscs

The basic principles of the design of the BNT Net were security, low cost and effectiveness.

Lets examine each of the machines in turn and see what they do.
