Derek, Did you ever get an answer to your Ethernet Hubs question? It certainly sounds to me as if you got more than you paid for. --Steve Augart Derek Fountain wrote at 16/02/2003 02:11 (GMT-0800):
I have, amongst my collection of bits, two ethernet hubs. One is by Netgear and one by Linksys. Both work. I have 3 machines, 1, 2 and 3.
I plug them all into the Netgear hub.
I log onto box 2 (at the console) and ping 3. Away to goes, every second. I open a tcpdump on 1 and watch the packets going by.
I now plug all the cables into the Linksys hub and repeat the experiment. Nothing!
When the machines are connected via the Linksys hub, tcpdump can't see the packets going from one machine to another, unless, it turns out, the machine running tcpdump is the one being pinged.
The Linksys device is a hub, not a switch! I know, I paid for it!
Anyone know why this is the case? Does Linksys stuff have some anti-snooping, don't-pass-through-to-promiscous cards sort of thing in it?
