Cheers for the replies - I think we'd covered most of what's been suggested but it's good to hear it from other people.

bsdpunk - basically it's just a hypothetical scenario...I'm not sure about why the Unix machines have ATM interfaces. It's the first assignment in a small class, and we were split into groups to look at different things (hardware, security, services, etc.). AFAIK the idea is more to give the lecturers an idea of our current understanding, and the talk's not meant to be very detailed.

But it's good to get the responses since we hadn't thought about time services or redundant systems, etc. Although I suspect that clusters and the like will be covered by other groups.

Like I say it's at a very simple level and I think the responses in this thread pretty much cover what we need to do. I'll maybe point out some things to the rest of the group, but we might just need to mention them in passing since I doubt we'll have time to add other stuff to the slides now.

Cheers,
