If you can not see the other traffic when connected to a switched hub this
is because our sniffer sits on a different physical network than the two
other machines that used to connect through a crossover cable.

On your sniffer, lock the speed of the interface to teh same speed as the
two other hosts connected to the
switched hub use and then you will sit on the same physical network as the
other two hosts and thus can sniff.
This would happen if the two other hosts run say 10mbit  on the switched hub
and your sniffer host attaches using 100mbit or vv.

If this does not help  then you dont have a hub at all but a real switch
that the vendor mismarketed as being a hub instead of a switch.

Actually my situation is/was this - My external router is connected to my
Firewall with a crossover cable (mostly for security) - I'd like to put a
hub between them so I can attach a PC with Ethereal to do packet traces
between the two devices. I've tried using a Linksys 5-Port auto-sensing hub
(product # - EFAH05W), but apparently this is a switched hub and I can only
see broadcast traffic on the segment.
