OK, I'll chime in: I got one of those key-chain sized Ethernet
loopback connectors. The idea is that you attach one end to a patch
cable and the other to the hub and if all is well the link light goes
on on the hub. So, I am sitting there admiring this wonder when all my
telnet sessions (OK, maybe SSH sessions) go away, webpages won't load
and AIM/Jabber disconnects. Of course the loopback device is causing a
broadcast storm and the hub isn't working well.
This supposedly does not happen on a switch... I haven't bothered to
try.
