It depends on what you want to do, but there is a utility that runs as a
daemon using the bpf and gives you the number of bytes to and from which IP
address and port number.  You can use an input file for your requirements.
I use it to monitor the amount of traffic that flows to and from a
particular C class and some of my own IP addresses.  You can run a
particular command and it writes the count out to file in a tab delimited
format.

The package also comes with trafshow which allows you to see what is
flowing over the network.  I got it from:

ftp://ftp.freebsd.org/pub/FreeBSD/incoming/bpft-2.0.tgz

Hugh Blandford.
