I heard back from the vendor regarding the hub/switch question that I mentioned on list about a month ago.
They sort of pointed me to this: http://www.webopedia.com/TERM/H/hub.html hub Last modified: Tuesday, February 18, 2003 A common connection point for devices in a network. Hubs are commonly used to connect segments of a LAN. A hub contains multiple ports. When a packet arrives at one port, it is copied to the other ports so that all segments of the LAN can see all packets. A passive hub serves simply as a conduit for the data, enabling it to go from one device (or segment) to another. So-called intelligent hubs include additional features that enables an administrator to monitor the traffic passing through the hub and to configure each port in the hub. Intelligent hubs are also called manageable hubs. A third type of hub, called a switching hub, actually reads the destination address of each packet and then forwards the packet to the correct port. So, gang, if you go looking for a hub to insert into a LAN segment for ntop monitoring, remember you explicitly want a "passive hub", not a switch and not a switching hub. Unfortunately, those puppies are getting hard to find. I'll also caution you that most 10/100 units have at least two segments (1 @ 10 and 1 @ 100) with a switch between them. -----Burton _______________________________________________ Ntop mailing list [EMAIL PROTECTED] http://listgateway.unipi.it/mailman/listinfo/ntop
