NAME

       queryparse - extract DNS queries from pcap capture files.

SYNOPSIS

       queryparse [-i input file ] [-o output file ] [-r recursion only ] [-R parse responses ]

DESCRIPTION

       queryparse  is  a  tool designed to extract DNS queries from pcap-formatted packet capture
       files and save them in  a  form  suitable  for  input  to  Nominum's  dnsperf  or  resperf
       benchmarking  tools.   queryparse  will  only  examine UDP packets, and currently supports
       Ethernet and Cisco HDLC frame types.

OPTIONS

       -i filename
              Attempt to extract DNS queries from filename,  which  should  be  a  pcap-formatted
              packet capture session (e.g., a file created by tcpdump or ethereal).

       -o filename
              Write  queries  to  filename in a format suitable for input to Nominum's dnsperf or
              resperf benchmarking tools.

       -r     Keep queries that do not have the RD (recursion desired) flag set.  This is  useful
              when parsing packet captures from authoritative nameservers.  When parsing captures
              from caching nameservers, do not use it unless you also want to parse the  outgoing
              queries from the nameserver.  Defaults to discarding queries with RD=0.

       -R     Parse responses (QR=1) instead of queries (QR=0).
