At the moment we have at least 50 PC compatible's, running MS-DOS, that are networked together on an ethernet. We have three types of ethernet boards that we use on the PC's: 1 - 3COM 501 and 505 card 2 - EXCELAN 8051-01 3 - Western Digital This are cards that allow you to hook up the PC directly into the ETHERNET using a 15 pin transceiver(ethernet) cable or using cheap net (coax or thin-ethernet) wire. These boards can be installed in any of the expansion slots that are available in your PC. The 3COM 501, 505 and Western Digital boards work with the FTP Software PC/TCP Network Software. The PC/TCP programs are a set of commands that operate under MS-DOS or PC-DOS 2.2 or higher. These programs provide a set of facilities that make the PC look like a network host rather than just a simulated intelligent terminal. EXCELAN has its own software for each of its boards as far as I know. Our scenario in our LAB is as follows: We have a single logical ETHERNET with gateways both to the Defense Data Network and the OSI Network (OSINET). The logical LAN is composed of three seperate physical segments in each of our three buildings here at the Navy Yard. Each of the LAN segments has a SUN workstation running BSD 4.2 UNIX as a local server and a bunch of PC's, Zenith 248's, that are attached to the LAN. The LAN segments are connected with intelligent protocol-transparent ETHERNET bridges. We have a MACINTOSH with an EXCELAN card that we use with the NCSA Telnet TCP/IP software ($20 per copy). We use our PC's regularly to get to our SUN's and we also connect to other hosts out in the network. If you have any other questions about this give us a call. Hope this helps you!! : - ) Adios Amigo! Lester R. Claudio Happy Networking! NARDAC Washington OSI LAB Washington Navy Yard Washington, D.C. 20374 (202)433-3630
