Hi
When I removed -u 1000 -g 1000 , "Cannot set NIC flags " is not displayed anymore,but no statistics are shown when the sniffer is stopped. I have run the application as root using "sudo su -" but it still doesn't show the statistics. About using iffps I think it shows how many packets are received by the kernel, I wanted to know how many packets are properly dumped by the sniffer into the pcap file (hoping that that's the inforamtion netsniff-ng gives).

Did you try use only super user ? Also as I understand in silent mode you should get stats after you terminate sniffing by Ctr-C, so would you provide these values & check if there is some drop rate ? Also may be you can try sniff w/o pcap filter and check interface stats via ifpps or some other tool which you like ?
