I tried ethereal yesterday and you don't need much to get started.
Just Capture for a short while and then look at the packets. If you
are in a lab type environment without too much traffic then you can
get by without a filter. Otherwise you can use a specific packet as
the base for a filter. You need to commit 1 hr to start getting some
idea :)

This is a pretty amazing tool given it's free status.
