If the tecpdump is running bpf, it should be able to report packet loss by
the kernel.  In the tcpdump distributed with redhat ver 6.1, it only show
the packet pick up the filter.

I'm not sure what you are referring to. Can you provide more details? Thanks.
Comment 2 Pekka Savola 2000-07-12 15:32:11 EDT
He means this:
24673 packets received by filter
0 packets dropped by kernel

Unfortunately, IIRC linux pcap doesn't support that, so it isn't printed.  BPF
etc. do, but that is another story.

(it -DPACKET_STATISTICS in libpcap DEFS causes an error)
