The network I'm on is built with 3 24-port hubs in serial, who is then
connected to a switch. But the hubs use some kind of encryption for the
packets. Recently I was at a friends place to check out his net (same thing
there) and on his PPC with Linux, all frames were passed to the kernel. It was
possible to see the source MAC on the packets. The NIC was a 3Com of some sort.
It seems some people on the net has full duplex turned on which of course ruins
performance pretty badly (ping varying between <1ms and 1000ms with packet
loss). The landlord who provides the connection doesn't really care, but if I
can view the source MAC of every packet I could view the amount of traffic from
each host and when ping suddenly starts going weird simply see who started
sending large amounts of packets.
