[Michel Bellemare]

is there any way to log all the traffic that uses the gnutella protocol?
i searched in the mailing list and google and found nothing.

I looked to at a tcpdump capture and it never uses the same port...

basically i want to control the number of bytes that goes out using
this protocol.

thank you very much!

you need a layer-7 classifier to magically figure out whether traffic on
port X is gnutella traffic.

you can try looking at:

You can do this for local traffic by using the owner module and :
	--cmd-owner
For a whole network I see any solutions but slightly modify the NuFW
system to be able to mark packet with an uid corresponding to the
application (same way it can mark with userid).

Hello Michel,

You need layer7 functionality in iptables. There is a good pattern available
for matching gnutella packets with layer7 module. Using the MARK option and
traffic control (tc) you will be able to restrict the bandwidth consumed by
the application.

Here is the documentation on this module:
http://l7-filter.sourceforge.net/


Hope this helps!
Regards,

Deepak Seshadri

And is there any way to log how many bytes the application is using
with each packet?
