trafshow displays network throughput in an ncurses frontend in a
console. I don't think there are any special requirements for trafshow
- perhaps you need to have the bpf option enabled in the kernel (which
it is by default?). Install it and try it it's in the ports under
ipfw can count network traffic using different rules, so for example you
could count all traffic bound for a certain address or interface using
ipfw add count all from any to 192.168.0.1 80
ipfw can also (very usefully) count traffic on a per uid basis.
ipfw does have to be enabled in the kernel though. See the handbook for
more info on this.
