"a crossover cable" Tracy

I don't know what that is.

I don't trust wireless.
I don't have a wireless phone either.
I regard any such wireless device a needless security risk. I prefer not to use a wireless mouse or keyboard either, as a spy could get key-logger type information.
With a hard wire, it's one less option the bad guys have.
And both computers are desk-top units. So wireless portability would be a non-benefit. And the tower is concrete and steel. So if I took one machine upstairs, it probably wouldn't get through.

Regarding the cable, I presume the cable would hook up to a port.
What sort of port? USB?
Firewire?
CoAx?

The Mac mini is a tiny box. It's got few ports, and all mine are now in use.

I've got a 4 into one hub. But it seems, I got a low speed hub, when I should have gotten a high speed hub.
But it works, so far.
