I think it's more for allowing ntop to provide status via SNMP (i.e. as an agent) than using snmp to collect info from remote machines. There's really no way to use SNMP to gather the info ntop needs. All you can get from snmp is network utilization, where ntop wants to see raw packets (or at minimum, ip+port+size data per flow). -- Dan Nelson [EMAIL PROTECTED] ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"

Hey Lowell,
Thanks for replying. Funny thing is, after it installed
from ports, it didn't have the executable bit set on it.
I saw it complain when I was booting in dmesg, and that's
when I set it executable. Still want to learn how to use
it properly, so I didn't uninstall it. I just moved the
script out /usr/local/etc/rc.d so it won't start auto.
Thanks for the help.
