[expert] Why I can't see all packets on my network segment?

[Zilvinas Atkociunas]

Hello mdk fans,

I hope someone could explain me why I can't see my segment packets on my
promisc workstation (mdk7.2, 2.2.17 kernel, running tcpdump turns PROMISC
flag to state on). I can watch only packets coming to and from my
workstation.

Thanks in advance,

zilvis

BTW: The label on the box where my ws is plugged into plainly says "Dual
speed 16-port Ethernet/Fast Ethernet Hub"  so this is not switch. ;-)
