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 /usr/ports/net/trafshow. ipfw can count network traffic using different rules, so for example you could count all traffic bound for a certain address or interface using something like: 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. -- Jez http://www.munk.nu/
