Use it to test your web server for DoS vulnerabilites, or just to figure out how many concurrent connections it can handle. SlowHTTPTest works on majority of Linux platforms, OS X and Cygwin - a Unix-like environment and command-line interface for Microsoft Windows, and comes with a Dockerfile to make things even easier. Check out [Wiki](https://github.com/shekyan/slowhttptest/wiki) for installation and usage details.

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 # absolute PATH. The drawback is that using absolute paths prevent a # configured tree to be moved without reconfiguration.

If necessary, add switches to CXX and # CXXCPP to enable support. VERSION may be '11' (for the C++11 standard) # or '14' (for the C++14 standard). # # The second argument, if specified, indicates whether you insist on an # extended mode (e.g. -std=gnu++11) or a strict conformance mode (e.g. # -std=c++11). If neither is specified, you get whatever works, with # preference for an extended mode. # # The third argument, if specified 'mandatory' or if left unspecified, # indicates that baseline support for the specified C++ standard is # required and that the macro should error out if no mode with that # support is found. If specified 'optional', then configuration proceeds # regardless, after defining HAVE_CXX${VERSION} if and only if a # supporting mode is found. # # LICENSE # # Copyright (c) 2008 Benjamin Kosnik # Copyright (c) 2012 Zack Weinberg # Copyright (c) 2013 Roy Stogner # Copyright (c) 2014, 2015 Google Inc.; contributed by Alexey Sokolov # Copyright (c) 2015 Paul Norman # Copyright (c) 2015 Moritz Klammler # # Copying and distribution of this file, with or without modification, are # permitted in any medium without royalty provided the copyright notice # and this notice are preserved.

slowhttptest .Nd Denial Of Service attacks simulator .Sh SYNOPSIS .Nm slowhttptest .Bk -words .Op Fl H|B|R|X .Op Fl g .Op Fl a Ar range start .Op Fl b Ar range limit .Op Fl c Ar number of connections .Op Fl d Ar all traffic directed through HTTP proxy at host:port .Op Fl e Ar probe traffic directed through HTTP proxy at host:port .Op Fl f Ar value of Content-type header .Op Fl i Ar interval in seconds .Op Fl k Ar request multiply factor .Op Fl l Ar test duration in seconds .Op Fl m Ar value of Accept header .Op Fl n Ar slow read interval in seconds .Op Fl o Ar output file path and/or name .Op Fl p Ar timeout for probe connection in seconds .Op Fl r Ar connection per second .Op Fl s Ar value of Content-Length header .Op Fl t Ar HTTP verb .Op Fl u Ar absolute URL .Op Fl v Ar output verbosity level .Op Fl w Ar advertised window size range start .Op Fl x Ar max length of follow up data .Op Fl y Ar advertised window size range end .Op Fl z Ar slow read from receive buffer in bytes .Ek .Sh DESCRIPTION The .Nm implements most common low-bandwidth Application Layer DoS attacks and produces CSV and HTML files with test statistics. .Pp Currently supported attacks are: .Pp .Bl -bullet -offset indent -compact .It Slowloris .It Slow HTTP POST .It Apache Range Header .It Slow Read .El .Pp The options are as follows: .Bl -tag -width Ds .It Fl g Forces .Nm to generate CSV and HTML files when test finishes with timestamp in filename. .It Fl H Starts .Nm in SlowLoris mode, sending unfinished HTTP requests. .It Fl B Starts .Nm in Slow POST mode, sending unfinished HTTP message bodies. .It Fl R Starts .Nm in Range Header mode, sending malicious Range Request header data. .It Fl X Starts .Nm in Slow Read mode, reading HTTP responses slowly. .It Fl a Ar start Sets the start value of range-specifier for Range Header attack. .It Fl b Ar bytes Sets the limit value of range-specifier for Range Header attack. .It Fl c Ar number of connections Specifies the target number of connections to establish during the test. .It Fl d Ar HTTP proxy host:port Specifies HTTP proxy server to connect to for all connections. .It Fl e Ar HTTP proxy host:port Specifies HTTP proxy server to connect to for probe connections. .It Fl f Ar content-type Specifies the value of Content-Type header. .It Fl i Ar seconds Specifies the interval between follow up data for slowrois and Slow POST tests. .It Fl k Ar pipeline factor Specifies number of times the resource would be requested per socket in Slow Read test. .It Fl l Ar seconds Specifies test duration in seconds. .It Fl m Ar accept Specifies the value of Accept header. .It Fl n Ar seconds Specifies the interval between read operations for Slow Read test. .It Fl o Ar file name Specifies custom file name, effective with \-g. .It Fl p Ar seconds Specifies the interval to wait for HTTP response on probe connection, before marking the server as DoSed. .It Fl r Ar connections per second Specifies the connection rate. .It Fl s Ar bytes Specifies the value of Content-Length header for Slow POST test. .It Fl t Ar HTTP verb Specifies the verb to use in HTTP request. .It Fl u Ar URL Specifies the URL. .It Fl v Ar level Specifies the verbosity level of logging. .It Fl w Ar bytes Specifies the start of the range the TCP advertised window size would be picked from in Slow Read test. .It Fl x Ar bytes Specifies the maximum length of follow up data for slowloris and Slow POST tests. .It Fl y Ar bytes Specifies the end of the range the TCP advertised window size would be picked from in Slow Read test. .It Fl z Ar bytes Specifies the number of bytes to read from receive buffer with each read() operation. .El .Sh EXAMPLES Start a slowloris test of host.example.com with 1000 connections, statistics goes into my_header_stats, interval between follow up headers is 10 seconds and connection rate is 200 connections per second: .Pp .Dl $ slowhttptest -c 1000 -H -g -o my_header_stats -i 10 -r 200 -t GET -u https://host.example.com/index.html -x 24 -p 3 .Pp Start slow POST test of host.example.com with 3000 connections, statistics goes into my_body_stats, interval between follow up headers is 110 seconds, connection rate is 200 connections per second, Content-Length header value is 8192, maximum length of follow up data is random value limited by 10 bytes and probe connections waits 3 seconds for HTTP response before marking server as DoSed: .Pp .Dl $ slowhttptest -c 3000 -B -g -o my_body_stats -i 110 -r 200 -s 8192 -t FAKEVERB -u http://host.example.com/loginform.html -x 10 -p 3 .Pp Start Range Header test of host.example.com with 1000 connections, use HEAD verb, and generate HTTP header Range:0-, x-1, x-2, x-3, ... x-y, where x is 10 and y is 3000, connection rate is 500: interval between follow up headers is 10 seconds and connection rate is 200 connections per second: .Pp .Dl $ slowhttptest -R -u http://host.example.com/ -t HEAD -c 1000 -a 10 -b 3000 -r 500 .Pp Start Slow Read test of host.example.com with 8000 connections, no statistics is generated, connection rate is 200 connections per second, TCP advertised window size is a random value between 512 and 1024, .Nm reads 32 bytes from each connections every 5 seconds, 3 requests are pipelined per each connections, probe connection waits 3 seconds for HTTP response before marking server as DoSed: .Pp .Dl $ slowhttptest -c 8000 -X -r 200 -w 512 -y 1024 -n 5 -z 32 -k 3 -u https://host.example.com/resources/index.html -p 3 .Pp Start Slow Read test of host.example.com through HTTP proxy server at 10.10.0.1:8080 with 8000 connections, no statistics is generated, the rest test values are default. .Nm most likely would test HTTP proxy server itself, rather than target server, but it all depends on the HTTP proxy server implementation: .Pp .Dl $ slowhttptest -d 10.10.0.1:8080 -c 8000 -X -u https://host.example.com/resources/index.html .Pp Start Slow Read test of host.example.com and direct probe traffic through HTTP proxy server at 10.10.0.1:8080 with 8000 connections, no statistics is generated, the rest test values are default. Specifying another connection channel for probe connections helps to make sure that .Nm shows valid statistics for availability of server under test: .Pp .Dl $ slowhttptest -e 10.10.0.1:8080 -c 8000 -X -u https://host.example.com/resources/index.html .Pp .Sh AUTHOR Sergey Shekyan .Aq shekyan@gmail.com . .Pp Project page .Aq https://github.com/shekyan/slowhttptest/ . slowhttptest-1.9.0/missing000077500000000000000000000153361426244000200157060ustar00rootroot00000000000000#! /bin/sh # Common wrapper for a few potentially missing GNU programs. scriptversion=2018-03-07.03; # UTC # Copyright (C) 1996-2020 Free Software Foundation, Inc. # Originally written by Fran,cois Pinard , 1996. # This program is free software; you can redistribute it and/or modify # it under the terms of the GNU General Public License as published by # the Free Software Foundation; either version 2, or (at your option) # any later version. # This program is distributed in the hope that it will be useful, # but WITHOUT ANY WARRANTY; without even the implied warranty of # MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
