Hello! Consider the following setup: LAN with local hosts <-> gateway running NetBSD <-> internet
Is it possible from the gateway to measure the amount of data fetched from the internet by a single LAN host over a speficic amount of time? Is there some networking tool which can provide this measurement? That LAN host should be identified through its IP address or MAC address and the measurement should regard in particular the data downloaded by the host. Sometimes vnstat is suggested in similar cases, but AFAIU it seems to measure only the amount of data sent or received from a local NIC, so it wouldn't be useful (if run on the gateway it would record the whole LAN activity involving the gateway). Bye! Rocky
