You can use ntop's netflow collector in conjunction with netflow-enabled switches to avoid spanning all of the traffic to the BSD box. That way, you're only getting a few UDP streams instead of a copy of all traffic crossing the switch - much easier to handle. We use that combination to collect data, then dump at regular intervals into a database for accounting/billing. - J -- Jeff Jirsa jjirsa@2advanced.net Senior Network Engineer 2advanced.net: Precision Hosting Platform
