Hello. I'm trying to write to disk between 3-7Gbit/sec (traffic changes a lot). Netsniff-ng is dropping packets, at least that is what statistics say.
Hardware and software details: 2 x E5-2620 64GB memory in 8 x 8 DIMMs to use every channel Intel X520 based card 12 x 3TB (2.7TB in fact) in RAID5 - 1 as hot spare, the rest gives me a healthy 28TB usable Ubuntu 12.04 on 3.8.x kernel XFS I run the software like this netsniff-ng -i eth2 -o /nsm/sensor_data/nsm2-eth2/dailylogs/2014-04-17/ --user 2551 --group 2551 -s --prefix snort.log. --verbose --ring-size 4000 iB --interval 1500 MiB --mmap --filter /etc/nsm/nsm2-eth2/bpf-pcap.ops BTW - there is a bug (integer overflow) and the buffer can't be larger than 4095MB. Anyway. What can I do to make netsniff lossless in this situation? Can it even do it? Also, I've disabled every kind of offloading feature I could find, and build the new Intel drivers with LRO=0. -- You received this message because you are subscribed to the Google Groups "netsniff-ng" group.
