NAME

       drool - DNS Replay Tool

SYNOPSIS

       drool command [ options ] < arguments >

DESCRIPTION

       drool  can  replay DNS traffic from packet capture (PCAP) files and send it to a specified
       server, with options such as to manipulate the timing between packets,  as  well  as  loop
       packets  infinitely  or for a set number of iterations.  This tool's goal is to be able to
       produce a high amount of UDP packets per second and TCP  sessions  per  second  on  common
       hardware.

       The purpose can be to simulate Distributed Denial of Service (DDoS) attacks on the DNS and
       measure normal DNS querying.  For example, the tool could enable you to take a snapshot of
       a  DDoS  and  be  able  to replay it later to test if new code or hardening techniques are
       useful, safe & effective.  Another example is to be able to replay a packet stream  for  a
       bug  that  is  sequence-  and/or  timing-related  in  order  to  validate  the efficacy of
       subsequent bug fixes.

       drool is divided into various commands for different scenarios.  Each command has it's own

       respdiff
              Replay  DNS  and store the responses along with the responses found in the PCAP for
              analysis with the respdiff tool-chain, see drool-respdiff(1).
