Hi
I'm using netsniff-ng for sniffing UDP packets on a network. For testign the
performance I tried to send packets using iperf with bandwidth 100M and length
250. When the capture was completed iperf says it send 28000 packets sent but
netsniff-ng shows a lesser value and it also shows 0% packet dropped. Could you
please help me solve this confusion on whats happening. I'm more intereted in
checking if the sniffer can handle upto 100Mbits/s data rate on the network
Normally, recording 100Mbit to pcap should not be an issue (unless you have
some weak
embedded system, etc) ... do you use things like GSO? How big is a packet that
you've
captured (does it match the 250b)? As Vadmin said, please provide some more
details.

Jishnu

Hi,
I am not an expert in netsniff-ng, but would you please give more
details about your setup (how do you run netsniff-ng, HW info, stats
info, examples of output iperf & netsniff-ng, etc ...).
Regards,
