that first problem has now been solved. It seems the old Ultra
machine had some problem or other (dodgy BIOS?? I dunno), we moved the two
cards to another machine and they work fine now. Thanks to all for the
help on that one.
We hooked up the two network cards and got them working
successfully. Great. Now, the plan is to set up a loop of BNC cable
going around the room pulling four machines onto a subnet with the
We can hook either eth? device to the main network and it is
possible to ping various outside world machines. It is also possible to
use the other machines directly on the network. However, the BNC loop
will not allow the two to see each other. Also the eth? devices can ping
themselves. My assumption that the story is this simple (ie only a loop
required) may perhaps show enormous naiivety and apologies if so.
Points of note:
1) the light on the subnet network card only lights on issuing a ping or
some such from that box (the main network NIC is always flashing, but
it's a very busy network, hence us trying to get off it).
2) a mate told me that some new NICs will not do this simple peer-to-peer
networking and require some other hardware to be present. Has anyone
heard of this? Is there a list of such cards in existence? What other
hardware is required??
