NAME
       dnsreplay - A PowerDNS nameserver debugging tool


SYNOPSIS
       dnsreplay [OPTION]...  FILENAME ADDRESS [PORT]


DESCRIPTION
       This  program  takes  recorded  questions  and  answers  and replays them to the specified nameserver and
       reporting afterwards which percentage of answers matched, were worse or better.

       dnsreplay compares the answers and some other metrics with the  actual  ones  with  those  found  in  the
       dumpfile.

       By default it only replay queries with recursion-desired flag set.


OPTIONS
       FILENAME
              is  expected  to be an PCAP file.  The queries are send to the DNS server specified as ADDRESS and
              PORT.

       ADDRESS
              IPv4 or IPv6 address of the nameserver to replay FILENAME to.

       PORT   if omitted, 53 will be used.

       --help | -h
              Show summary of options.

       --packet-limit NUM
              Stop after replaying NUM packets.  Default for NUM is 0, which means no limit.

       --quiet FLAG
              If FLAG is set to 1.  dnsreplay will not be very noisy with its output.  This is the default.

       --recursive FLAG
              If FLAG is set to 1.  dnsreplay will only replay queries with recursion desired flag set.  This is
              the default.

       --speedup FACTOR
              Replay queries with this speedup FACTOR.  Default is 1.

       --timeout-msec MSEC
              Wait at least MSEC milliseconds for a reply.  Default is 500.


BUGS
       dnsreplay has no certain handling for timeouts.  It handles around at most 65536 outstanding answers.
