Not that I know of, and I find it hard to believe ntop would start
default on any distro, especially debian. Must have got in via another
odd dependency. It's typically a standalone app and webserver of its
own for diagnosing tcp/udp application flows from the flag level, not
typically used by most outside of networking folk. I'm not sure it even
offers a direct api for another app to use unless an app is scraping, I
suppose its possible another has it as a dependency.
It usually is stable under low loads, so if it's freaking out, either
its a bad build, you have a lot of broadcast/unicast flooding occurring
that it's seeing, or "normal" traffic of your own its crunching on.
I've killed it with gratuitous bittorrent connections on a slow test
box.
What does it show when you http to:
http://localhost:3000
Should be default port. If you get curious, maybe you should. :)
