I am trying to capture unicast traffic from host A to host B by using
host C to sniff on a Linksys 5-port Hub (the newest Linksys/Cisco version).
However it seems this hub is not acting as a repeater. A promiscuous
host C will not detect unicast traffic that is not intended for it.
I've tried various nodes to be the promiscuous host to see if it was a
datalink issue, but I get the same results.
Also the hub's activity lights will only blink for the sending and
receiving unit when packets are transmitted.
We've seen this on 3 modern devices labeled as hubs.
Has anyone else experienced this with modern "hubs"?
Is it now just cheaper to make all devices switching and then label some
as hubs as others as switches?
