+
+ Release 2.0.0
+
+ This major release is a complete rewrite of drool to Lua using dnsjit!
+
+ This includes two commands:
+ - `drool replay`: 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.
+ - `drool respdiff`: replay DNS queries found in the PCAP, but only if
+ a correlating response is also found. The query, original response
+ and the received response is then stored into a LMDB database which
+ can then be used by respdiff by CZ.NIC (see https://gitlab.labs.nic.cz/knot/respdiff)
+ for analysis.
+
+ See `man drool`, `man drool reply` and `man drool respdiff` for more
+ information.

+
+ Release 1.1.0
+
+ Rework of the timing code to make it more effective, based on
+ proof-of-concept from Petr Špaček @pspacek (CZ.NIC).
+
+ The `best_effort` timing mode is now deprecated, this is now the same
+ mode as `keep` and the warnings `keep` made when unable to follow
+ timings have been removed.

+
+ Mostly documentation updates and clarifications but also a new timing
+ mode `best_effort` to send packets as fast as possible without warnings
+ and a correct usage of `nanosleep()` on systems that does not support
+ `clock_nanosleep()`.

+
+2017-03-02 Jerry Lundström
+
+ Release 1.0.0-alpha.3
+
+ Reworked some of the client code to better handle stream sockets (TCP),
+ retrys to send query if the system's sockets are exhausted. Can send
+ queries as the original protocol or force them into UDP or TCP.
+
+ Default number of client pools running per context is now 1, increase
+ this if you want to push UDP queries. For TCP this has little effect
+ since you will most likely hit system limits before that.
+
+ Config changes:
+ - Added `context client_pools num;`
+ - Added `client_pool max_reuse_clients num;`
+ - Added `client_pool sendas what;`
+
+ Other changes:
+ - Add timing details to warning about not keeping up with timings
+
+ f8805da TCP, send as, proper shutdown
+ 800e971 Include CHANGES in dist
+ cae9834 Honor previous fd flags
+
+2017-02-21 Jerry Lundström
+
+ Release 1.0.0-alpha.2
+
+ This release implements the core engine and most of the network code
+ which consists of:
+ - parsing DNS packet from input using omg-dns
+ - sending queries to a client pool using sllq
+ - processing queries using client objects and libev event loops
+
+ Handling results/responses have yet been implemented.
+
+ Command line option changes:
+ - Added `-R` to specify read mode for PCAP files
+ - Removed `-w` and `-o`
+
+ Config changes:
+ - Added `timing ignore;`
+ - Added `timing keep;`
+ - Added `timing add nanoseconds;`
+ - Added `timing reduce nanoseconds;`
+ - Added `timing multiply float;`, note: no logic added yet
+ - Added `client_pool target "ip" "port";`
+ - Added `client_pool max_clients num;`
+ - Added `client_pool client_ttl float;`
+ - Added `client_pool skip_reply;`
+ - Removed `read`, `input`, `write` and `output`
+
+ 246c9ad Update README with example, build info and copyright etc
+ 94ce650 Loop/iteration read, lag detect and documentation
+ 7bda852 Send as, multi client pools per context
+ e233f51 Tweaks
+ 3d0dae4 Rework network code

+ available
+ bbdcb07 A lot of more stuff
+
+2017-01-20 Jerry Lundström
+
+ Release 1.0.0-alpha.1

+# DNS Replay Tool (drool)
+
+`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.
+
+More information may be found here:
+- https://www.dns-oarc.net/tools/drool
+
+Issues should be reported here:
+- https://github.com/DNS-OARC/drool/issues
+
+General support and discussion:
+- Mattermost: https://chat.dns-oarc.net/community/channels/oarc-software
+
+## Known Issues
+
+- IP fragments are currently not processed and will be discarded.
+- TCP sessions are not reassembled, each packet is parsed as DNS after
+ discarding the first two bytes.
+
+## Usage example
+
+Send all DNS queries twice as fast as found in the PCAP file to localhost
+using UDP.
+
+```shell
+drool replay --timing multiply=0.5 --no-tcp file.pcap 127.0.0.1 53
+```
+
+Send all DNS queries over TCP to localhost as they were recorded.
+
+```shell
+drool replay --timing keep --no-udp file.pcap 127.0.0.1 53
+```
+
+Take all DNS queries found in the PCAP file and send them as fast as possible
+over UDP to localhost by ignoring both timings, replies and starting 3 threads
+that will simultaneously send queries.
+
+```shell
+drool replay --no-tcp --no-responses --threads --udp-threads 3 file.pcap 127.0.0.1 53
+```
+
+## Dependencies
+
+`drool` is built upon [dnsjit](https://github.com/DNS-OARC/dnsjit) and
+requires it to be installed along with autoconf/automake.
+
+## Build
+
+```
+sh autogen.sh
+./configure
+make
+make test
+make install
+```

+# For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
+# $ac_aux_dir to '$srcdir/foo'. In other projects, it is set to
+# '$srcdir', '$srcdir/..', or '$srcdir/../..'.
+#
+# Of course, Automake must honor this variable whenever it calls a
+# tool from the auxiliary directory. The problem is that $srcdir (and
+# therefore $ac_aux_dir as well) can be either absolute or relative,
+# depending on how configure is run. This is pretty annoying, since
+# it makes $ac_aux_dir quite unusable in subdirectories: in the top
+# source directory, any form will work fine, but in subdirectories a
+# relative path needs to be adjusted first.
+#
+# $ac_aux_dir/missing
+# fails when called from a subdirectory if $ac_aux_dir is relative
+# $top_srcdir/$ac_aux_dir/missing
+# fails if $ac_aux_dir is absolute,
+# fails when called from a subdirectory in a VPATH build with
+# a relative $ac_aux_dir
+#
+# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
+# are both prefixed by $srcdir. In an in-source build this is usually
+# harmless because $srcdir is '.', but things will broke when you
+# start a VPATH build or use an absolute $srcdir.
+#
+# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
+# iff we strip the leading $srcdir from $ac_aux_dir. That would be:
+# am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
+# and then we would define $MISSING as
+# MISSING="\${SHELL} $am_aux_dir/missing"
+# This will work as long as MISSING is not called from configure, because
+# unfortunately $(top_srcdir) has no meaning in configure.
+# However there are other variables, like CC, which are often used in
+# configure, and could therefore not use this "fixed" $ac_aux_dir.
+#
+# Another solution, used here, is to always expand $ac_aux_dir to an

+
+Configuration:
+ -h, --help display this help and exit
+ --help=short display options specific to this package
+ --help=recursive display the short help of all the included packages
+ -V, --version display version information and exit

+.SH NAME
+drool \- DNS Replay Tool
+.SH SYNOPSIS
+.B drool replay
+[
+.I options
+]
+.B file
+.B host
+.B port
+.SH DESCRIPTION
+\fBdrool\fR 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.
+.SH OPTIONS
+These options are specific for the
+.B replay
+command, see
+.IR drool (1)
+for generic options.
+.TP
+.B \-D
+Show DNS queries and responses as processing goes.
+.TP
+.B \-n \-\-no\-responses
+Do not wait for responses before sending next request.
+.TP
+.B \-\-no\-tcp
+Do not use TCP.
+.TP
+.B \-\-no\-udp
+Do not use UDP.
+.TP
+.B \-T \-\-threads
+Use threads.

+.B drool respdiff
+[
+.I options
+]
+.B path
+.B name
+.B file
+.B name
+.B host
+.B port
+.SH DESCRIPTION
+This tool is to be used in conjunction with the tool-chain
+.I respdiff
+by CZ.NIC (see
+.IR https://gitlab.labs.nic.cz/knot/respdiff ).
+.LP
+It will replay DNS queries found in the PCAP, but only if a correlating
+response is also found, against the target
+.I host
+and
+.IR port .
+The query, original response and the received response is then stored into
+a LMDB database located at
+.IR path .
+The
+.I name
+before the PCAP
+.I file
+and the
+.I name
+before the target
+.I host
+are stored in the meta table which should correspond with the configuration
+use for
+.I respdiff
+in order for it to be able to read the results correctly.
+.SH OPTIONS
+These options are specific for the
+.B respdiff
+command, see
+.IR drool (1)
+for generic options.
+.TP
+.B \-D
+Show DNS queries and responses as processing goes.
+.TP
+.B \-\-no\-tcp
+Do not use TCP.
+.TP
+.B \-\-no\-udp
+Do not use UDP.
+.TP
+.B \-T \-\-threads
+Use threads.
+.TP
+.B \-\-tcp\-threads N
+Set the number of TCP threads to use, default 2.
+.TP
+.B \-\-udp\-threads N
+Set the number of UDP threads to use, default 4.
+.TP
+.B \-\-timeout N.N
+Set timeout for waiting on responses [seconds.nanoseconds], default 10.0.
+.TP
+.B \-\-size BYTES
+Set the size (in bytes, multiple of OS page size) of the LMDB database, default 10485760.
+.SH DATABASE SIZE
+Note that you will need to set a database size that is large enough for all
+queries, all original responses, all received responses and all analysis done
+by
+.I respdiff
+tool-chain in order for a successful analysis to be done.
+.SH EXAMPLE
+This example replays a PCAP file against localhost and then uses the
+.I respdiff
+tool-chain to analyze the results.

+.SH NAME
+drool \- DNS Replay Tool
+.SH SYNOPSIS
+.B drool command
+[
+.I options
+] <
+.I arguments
+>
+.SH DESCRIPTION
+.B 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.
+.SH COMMANDS
+.B 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.
+.TP
+.B replay
+Replay DNS from a PCAP file, see
+.IR drool-replay (1).
+.TP
+.B respdiff
+Replay DNS and store the responses along with the responses found in the PCAP
+for analysis with the
+.I respdiff
+tool-chain, see
+.IR drool-respdiff (1).
+.SH OPTIONS
+These options are generic for all
+.B drool
+commands.
+.TP
+.B \-\-csv
+Output statistics as CSV.
+.TP
+.B \-\-json
+Output statistics as JSON.
+.TP
+.B \-v \-\-verbose
+Enable verbose logging, can be given multiple times to increase verbosity level.
+.TP
+.B \-h \-\-help
+Print help and exit.
+.TP
+.B \-V \-\-version
+Print version and exit.
+.SH EXIT VALUES
+0 \- no error
+.br
+1 \- generic error
