There's nothing out of the box for this. There are several ways to go about this. If however you're using ipfw or pf, I think both are capable of tracking flow stats so imho you'd be better off scripting your thresholds and policing functions using the fw tools. Else, perhaps try wget to pull stats from ntop as needed.

I can see who are the top bandwidth users in our network by browsing ntop GUI; now I want to achieve the below task: ntop can automatically trigger an alarm by some condition, such as one IP's bandwidth is above one threshold value, then my linux firewall can block or limit this IP according to this alarm. Could you help to provide your intruction, experience or comments about my probelm? Thanks in advance!
