Hi,
we're happily using ntop 2.0 on suse 7.3.
Ntop shows traffic for several ports in the Stats-Webinterface
(trafficStats.html).
Is there any possibility to add any other but the standard-ports by
configuration or do I have to modify the source?
Background: I'd like to get a quick'n dirtya

I think you can use the -F parameter for that.

As I'm busy researching the network behaviour of such peer-to-peer
applications and I think there are two options to make ntop monitor such
protocols:
* Write a plug-in to handle the protocol. However AFAIK a plug-in cannot
access the content of reassembled TCP transmissions, which is needed for
Um... I don't see any examples, but the structures (look at
pluginSkeleton.c) seem to show that you can indeed see the packet
contents:
Yes, you can see the packet contents, but this is on IP level, while most
peer-to-peer protocols are layered on top of TCP. So you need to (at least
Yes, you can see the packet contents, but this is on
IP level, while most

you need to (at least
partially) implement the TCP protocol in the plugin to
do a good analysis,
which is a large overhead, especially since it's
already done
Don't turn on netflow? :-)
Looks like a common problem - quoting from Cisco's documentation:
Cisco IOS Router-Based NetFlow Aggregation
Customers can expect a large volume of export data from NetFlow when it is
enabled on many interfaces on high-end routers that switch many flows per
unit time
How about using a filter to reduce what you're looking at?
Hmmm that's a possible. What we'd really need is a filter that would
provide me with an aproximate bandwidth usage that wwe could use for
accounting.
How would I go about setting up a filter to do this?

It uses standard syntax, like tcpdump.
How about a combo - (Linux only?) - use netfilter's
limiting syntax to mark a small % of packets (TOS or
firemark) and then the filter to select only those...
