Hi
I am trying to evaluate how tcpdump performs with different libpcap versions
and other packet capture libraries. How do I re-compile TCPDUMP to work with
a different libpacp ?

Hi
Is there an option to make tcpdump print the number of packet it
captures/process per second. It prints the number of packets handled as a
summary before exiting but that is a cumulative figure. I want to find out
the rate of packet processing by tcpdump when the pipe is full.

Is the approximation because of the fact that NIC card generarates interrupt
only after some number of packets arrive ?. Does device polling affect time
stamp ? At what stage of capture time stamping is done ?

Hi
After Running TCPDUMP say the following amount is obtained
9298933 packets captured
9298932 packets received by filter
2871368 packets dropped by kernel
Can we assume the percentage of packets dropped during capture on that
particular interface is approximately packets dropped /(packets dropp
f using a shell, I need to run it over a web interface.

What is the meaning of dropped by interface ?
Dropped by kernel means packets dropped due to lack of memory at the kernel
in the same way what does interface drop signifies ?
