[wplug] Tapping into an Ethernet connection

Fri May 15 10:04:16 EDT 2009

I have been trying to tap into an Ethernet connection between two pieces
of equipment that we have designed.  I have found a cheap hub at only
one Best Buy that allows me to use WireShark to view the messages.
However they are only 10Meg Hubs and eventually I am going to need to
run at 100Meg.

I have two other Linksys hubs (NH1005 and EFAH08W) that are listed as
"Network Hub" and "Workgroup Hub".  Both of these older (5 yr?) devices
seem to be switches and not hubs.  I looked on line and can only find
used 4 port hubs, but I am concerned that they are also just switches.
Is there any way to know if a hub is a hub and not a switch?  Or, is
there another way to use WireShark to view traffic?
