Networking Problem!

[Neeraj <neerajk@cse.iitk.ac.in>]

Hello Friends,

I am having a problem , which is kinda userland one, but needs help from the 
kernel gurus! I have a machine in which I set the ethrnet card into promiscuous 
mode! After setting the card into the promiscuous mode, I need to check how many 
TCP packets are read by the kernel from the interface till the time I don't 
reset the interface into non-promiscuous mode! Is there any system call, or 
parameter in the /proc  filesystem or any other way in which I can ask the 
kernel to give me just the count of tcp packets! And I just need the count sir! 

I will also tell you the reason why I want to do this : The machine is being 
stress tested on a 100Mbps network and we want to see how much amount of traffic 
can the machine sniff and dump on the disk wthout any losses and if there are 
some losses then what is that percentage! 

Thanks and Regards
Neeraj 


PS: If this off topic then I am sorry, but could'nt get answers  from anywhere 
else so tried asking you.
