Hi
I have double checked, it seems if I run with "-s" option with the application saving
files on to a folder "--out /share/capture/job/" will not give any statistics up on
stopping it using ^C.
And it is giving a "Cannot set NIC Flags" message at the end. So I'm not able
to check if the sniffer has captured all the packets. Could you please help me with this.
Daniel,
I might be wrong but I looked into the code and see this condition in
the netsniff-ng.c:
1097 if (!(ctx->dump_dir && ctx->print_mode == PRINT_NONE)) {
1098 sock_rx_net_stats(sock, frame_count);
which seems that really netsniff-ng will do not print stats in silent
mode and if dump to the folder ?
Hmm, fair enough. Maybe this should be reworked. We dump intermediate stats
in print_pcap_file_stats(), which you should see with -V option in this mode.
I.e. it shows [captured pkts/drops] after each rotation. Afaik, whenever you
fetch PACKET_STATISTICS via getsockopt(2), they're cleared in the kernel again.
