Re: Making Two LANs?



Are you working on a special project for the US army? Whatever the "device" is it seems to be a national secret! It must be a VPM...

I believe Kurt provided enough info for me. Plug it into the second PCI, and follow the yellow brick road. I recall that when I did this about 3 months ago, it was almost ridiculously simple. The device is a video box with a fixed ethernet address. It's an interface to a camera that takes pictures of the sky. It works fine. No, I don't work for any govt. secret agencies. :-) It's been working quite well since I installed it.

You seem to be having a hard time accepting the fact that this device has no conventional connection to the computer. No firewire, no USB, no printer port, zippo. Ethernet--that's it. I hope you don't want a circuit diagram. :-) It works on Linux, Win and Apple under Python. There you have it ...

Let me simplify matters. Suppose you have a single computer and you want to add a device that has a fixed ethernet address, it is not a computer, and is completely networkable.


You don't,..it is that simple,...continued below.

An ethernet address is a Layer2 MAC address and is not "completely networkable" because it only functions at Layer2. I am pretty sure that you are misdescribing the situation which makes it impossible to either understand what you really have or suggest anything to do about it.

Further it has no dial-up or communications ability other than to record data and send it back to the PC it is attached to. How would you go about making a connection via the networking or other facilities of W2K?


You don't.
It won't happen,...at least not according to how you are describing everything.
That is why I am asking the questions that I asked. The questions I ask are specific and are for a reason.

A machine cannot have two functioning "interfaces" on the same subnet that are active at the same time without unpredictable behavor (at best). The "interfaces" would have to be Teamed or have one left disabled. On the other hand if the interfaces are in different subnets then other hosts on the one subnet can *never* access the machine by the interface of the opposite subnet unless that PC is configured to operate as a router (which pretty much isn't going to happen).

So if you think about these things for a bit you will see why I have so difficult of a time understanding the situation and how it was ever supposed to operate in the first place.
Terminology is extremely important,...as one of my heros always says, "...words mean things".

So what *is* this device? Are we talking about a Firewire based device (a "1394 Device").
