ntop and trafshow from the ports are both very good. They require that you have BPF (Berkeley Packet Filter) compiled into the kernel (its there by default, I believe), and read access to /dev/bpf*. By default, only root has that - I sometimes give it to wheel, just so that I don't need to su to root in order to run the monitor. For longer term monitoring, if you install net-snmp and mrtg from the ports you can get nice graphs showing bandwidth usage and trends (as well as use any SNMP monitor program to keep tabs on bandwidth use). IPA (IP Accounting), also in ports, is nice if you need fine grained monitoring - for example monitoring specific services/IPs' bandwidth use over time. It requires that you use count rules in your firewall, and works off there. Hope that helps, Herbert. _______________________________________________ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"
