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.

COMMANDS

       drool  is divided into various commands for different scenarios.  Each command has it's own man-page, may
       take different arguments and may have additional options.
