10/100 hubs always 'switch' between the 10 and the 100 sides, because there
is more traffic on the 100 side which would flood the 10 side. (I suppose a
really intelligent hub could pass all the 10M traffic up to the 100M hub,
but I don't know of one that does. If someone does they'll come back to
you.)
The problem I have is that I keep a 10M card in my laptop, because I might
need the BNC connection. In order to analyse 10/100 networks I carry a small
10M hub with me, which I put between the machine-on-test and the 10/100 hub.
This pulls the conversation through the switch in the hub, so that it is
visible.
If your problem is that your ethereal-machine is on the 100M half and the
conversation is in the 10M half then connect a 10M hub between the
ethereal-machine and the 10/100 hub. This will drag your ethernet card down
to 10M.
4 port 10M hubs are dirt cheap.
Don't forget that when connecting a hub to a hub then you either need a
cross-over cable or _one_ of the connections must be to a cross-over socket
on one of the hubs and the switch to cross it over should be set.
(Generally, when the lights come on you've got it right.)

Subject: [Ethereal-users] hub for ethereal
I ran into the problem mentioned in the FAQ with a 10/100 hub that
doesn't pass packets from the 10 interface to the 100 and vice-versa.
Can anyone recommend a hub that will work 10/100 with ethereal?
TIA,
Terry Todd
