To Mr. Diepeveen's suggestions below, I would add that a more standard,
straight forward Ethernet topography of two or more systems and an
active Ethernet hub would be a little easier ...
Cross over cables (cross-utp cables) often have problems with older NIC
cards = failure or erratic behavior. The presence of a decent hub (or
multi port router or switch) can use industry standard cables (straight
through, "non cross over" cables). This may save a world of debugging
grief later. Besides, there are several 4-port and 5-port Ethernet hubs
that cost just a little more than that "special" cable.
Example: Radio Shack
F004&product%5Fid=278%2D2011 ... and ...
F002&product%5Fid=25%2D3060 ... or checkout your local supply depot.
After years of putting these kinds of systems together, I can tell you
that you will find that as soon as you add system #3 and #4 to your
mix, you will have to go to a hub in any case and discard the cross
over cable ...
Also, in order to achieve any kind of decent performance you should
consider 10/100baseT hubs (or routers or switches) and those cross over
cables become even more problematic as speed increases.
(Building a beowulf system is certainly a good use of your continuing
military education and I would not hesitate in contacting your base
supply folks for assistance in lashing several g'ment issue systems
together. Who knows, if you become an expert in this, your advancement
may be enhanced significantly. Mention Rear Admiral Grace Hooper,
co-inventor of FORTRAN, BASIC and COBOL, as one of your heros: " GRACE
HOOPER , LA PRIMERA HACKER DE LA HISTORIA ... " /
