    Switch is short for "port-switching hub". The 'hub' bit describes the
    network topology, and 'port-switching' describes the way that it directs
    packets.

    Though, logically, the "switch" provides point-to-point links (albeit
    forever changing with need) whereas the "hub" designation refers to a
    logical topology that matches the physical topology.

    To what extent are hubs really switches these days? I ask because I want
    to get myself a hub with a view to packet capture, but if it's actually a
    switch without a 'forward everywhere' option then it won't do what I want.

    10BaseT stuff is probably a hub, 100BaseT much more likely to be a
    switch. You can actually sniff switches, but it's a lot more hassle
    than just listening to an unswitched hub.

    Only way I know of is spoofed ARP replies so that broadcast MAC addresses
    are cached. Any hints you'd offer on other techniques?

    ARP poisoning is the only way I know. Ettercap is supposed to be good
    but I've never tried it.
