This can get tricky. You need to be on a port that sees all of the traffic - read that as 'not a switch port'. By definition a switch will only show you packets destined for your computer.
If you really want to see what going on you need a hub or a managed switch that can replicate all traffic onto a port. Another option is to use a wireless card in promiscious mode - a mode where you see all of the traffic. Ethereal will do this with (I think) most common wireless cards.
