I use tcpdump to collect the dns traffic between the local DNS server and hosts in our university(not include the dns traffic between the local DNS server and upper DNS server) and store as pcap format.
I use passivedns1.0 to process the dns traffic. But there are some errors. Why the total DNS records allocated is zero? Why?
