Ivan, Argus (qosient.com/argus) is your friend, e.g: argus -r your.pcap -w - | ra -n -z -L0 Russ McRee wrote a nice Argus 3 intro here: http://holisticinfosec.org/toolsmith/docs/november2007.pdf Tcpdstat is not the right tool for this task. If you do want summary stats, Tshark does a better job: tshark -n -r your.pcap -q -z io,phs I cover these in my books and blog.
