It is much easier to use ethereal. It is a nice GUI interface that allows you to sort the results by time the packet arrived, port, source, destination etc. It is pretty easy to install from the rpm and does not need any special configs to simply capture packets. You can look up the syntax to filter by port, but since you can sort the results by port, for short term captures, I just capture everything and the sort it.
