Hello again,

Now that I'm thinking better, this approach is not similar with tcpdump 
because if I monitor the application that reads the data, I won't see it 
until it is actualy read. The idea of my sniffer is to debug the device 
that runs on the other side so it would be interesting to display 
something as soon as it arrives rather than waiting till the application 
reads the data.
I will try to see if there is some support provided in the kernel.

Thanks,
