It uses +those values to create a `Makefile' in each directory of the package. +It may also create one or more `.h' files containing system-dependent +definitions. Finally, it creates a shell script `config.status' that +you can run in the future to recreate the current configuration, and a +file `config.log' containing compiler output (useful mainly for +debugging `configure'). + + It can also use an optional file (typically called `config.cache' +and enabled with `--cache-file=config.cache' or simply `-C') that saves +the results of its tests to speed up reconfiguring. (Caching is +disabled by default to prevent problems with accidental use of stale +cache files.) + + If you need to do unusual things to compile the package, please try +to figure out how `configure' could check whether to do them, and mail +diffs or instructions to the address given in the `README' so they can +be considered for the next release. If you are using the cache, and at +some point `config.cache' contains results you don't want to keep, you +may remove or edit it. + + The file `configure.ac' (or `configure.in') is used to create +`configure' by a program called `autoconf'. You only need +`configure.ac' if you want to change it or regenerate `configure' using +a newer version of `autoconf'. + +The simplest way to compile this package is: + + 1. `cd' to the directory containing the package's source code and type + `./configure' to configure the package for your system. If you're + using `csh' on an old version of System V, you might need to type + `sh ./configure' instead to prevent `csh' from trying to execute + `configure' itself. + + Running `configure' takes awhile. While running, it prints some + messages telling which features it is checking for. + + 2. Type `make' to compile the package. + + 3. Optionally, type `make check' to run any self-tests that come with + the package. + + 4. Type `make install' to install the programs and any data files and + documentation. + + 5. You can remove the program binaries and object files from the + source code directory by typing `make clean'. To also remove the + files that `configure' created (so you can compile the package for + a different kind of computer), type `make distclean'. There is + also a `make maintainer-clean' target, but that is intended mainly + for the package's developers. If you use it, you may have to get + all sorts of other programs in order to regenerate files that came + with the distribution. + +Compilers and Options +===================== + +Some systems require unusual options for compilation or linking that the +`configure' script does not know about. Run `./configure --help' for +details on some of the pertinent environment variables. + + You can give `configure' initial values for configuration parameters +by setting variables in the command line or in the environment. Here +is an example: + + ./configure CC=c89 CFLAGS=-O2 LIBS=-lposix + + *Note Defining Variables::, for more details. + +Compiling For Multiple Architectures +==================================== + +You can compile the package for more than one kind of computer at the +same time, by placing the object files for each architecture in their +own directory. To do this, you must use a version of `make' that +supports the `VPATH' variable, such as GNU `make'. `cd' to the +directory where you want the object files and executables to go and run +the `configure' script. `configure' automatically checks for the +source code in the directory that `configure' is in and in `..'. + + If you have to use a `make' that does not support the `VPATH' +variable, you have to compile the package for one architecture at a +time in the source code directory. After you have installed the +package for one architecture, use `make distclean' before reconfiguring +for another architecture. + +Installation Names +================== + +By default, `make install' installs the package's commands under +`/usr/local/bin', include files under `/usr/local/include', etc. You +can specify an installation prefix other than `/usr/local' by giving +`configure' the option `--prefix=PREFIX'. + + You can specify separate installation prefixes for +architecture-specific files and architecture-independent files. If you +pass the option `--exec-prefix=PREFIX' to `configure', the package uses +PREFIX as the prefix for installing programs and libraries. +Documentation and other data files still use the regular prefix. + + In addition, if you use an unusual directory layout you can give +options like `--bindir=DIR' to specify different values for particular +kinds of files. Run `configure --help' for a list of the directories +you can set and what kinds of files go in them. + + If the package supports it, you can cause programs to be installed +with an extra prefix or suffix on their names by giving `configure' the +option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'. + +Optional Features +================= + +Some packages pay attention to `--enable-FEATURE' options to +`configure', where FEATURE indicates an optional part of the package. +They may also pay attention to `--with-PACKAGE' options, where PACKAGE +is something like `gnu-as' or `x' (for the X Window System). The +`README' should mention any `--enable-' and `--with-' options that the +package recognizes. + + For packages that use the X Window System, `configure' can usually +find the X include and library files automatically, but if it doesn't, +you can use the `configure' options `--x-includes=DIR' and +`--x-libraries=DIR' to specify their locations. + +Specifying the System Type +========================== + +There may be some features `configure' cannot figure out automatically, +but needs to determine by the type of machine the package will run on. +Usually, assuming the package is built to be run on the _same_ +architectures, `configure' can figure that out, but if it prints a +message saying it cannot guess the machine type, give it the +`--build=TYPE' option. TYPE can either be a short name for the system +type, such as `sun4', or a canonical name which has the form: + + CPU-COMPANY-SYSTEM + +where SYSTEM can have one of these forms: + + OS KERNEL-OS + + See the file `config.sub' for the possible values of each field. If +`config.sub' isn't included in this package, then this package doesn't +need to know the machine type. + + If you are _building_ compiler tools for cross-compiling, you should +use the option `--target=TYPE' to select the type of system they will +produce code for. + + If you want to _use_ a cross compiler, that generates code for a +platform different from the build platform, you should specify the +"host" platform (i.e., that on which the generated programs will +eventually be run) with `--host=TYPE'. + +Sharing Defaults +================ + +If you want to set default values for `configure' scripts to share, you +can create a site shell script called `config.site' that gives default +values for variables like `CC', `cache_file', and `prefix'. +`configure' looks for `PREFIX/share/config.site' if it exists, then +`PREFIX/etc/config.site' if it exists. Or, you can set the +`CONFIG_SITE' environment variable to the location of the site script. +A warning: not all `configure' scripts look for a site script. + +Defining Variables +================== + +Variables not defined in a site shell script can be set in the +environment passed to `configure'. However, some packages may run +configure again during the build, and the customized values of these +variables may be lost. In order to avoid this problem, you should set +them in the `configure' command line, using `VAR=value'. For example: + + ./configure CC=/usr/local2/bin/gcc + +causes the specified `gcc' to be used as the C compiler (unless it is +overridden in the site shell script). Here is a another example: + + /bin/bash ./configure CONFIG_SHELL=/bin/bash + +Here the `CONFIG_SHELL=/bin/bash' operand causes subsequent +configuration-related scripts to be executed by `/bin/bash'. + +`configure' Invocation +====================== + +`configure' recognizes the following options to control how it operates. + +`--help' +`-h' + Print a summary of the options to `configure', and exit. + +`--version' +`-V' + Print the version of Autoconf used to generate the `configure' + script, and exit. + +`--cache-file=FILE' + Enable the cache: use and save the results of the tests in FILE, + traditionally `config.cache'. FILE defaults to `/dev/null' to + disable caching. + +`--config-cache' +`-C' + Alias for `--cache-file=config.cache'. + +`--quiet' +`--silent' +`-q' + Do not print messages saying which checks are being made. To + suppress all normal output, redirect it to `/dev/null' (any error + messages will still be shown). + +`--srcdir=DIR' + Look for the package's source code in directory DIR. Usually + `configure' can determine that directory automatically. + +`configure' also accepts some other, not widely useful, options. Run +`configure --help' for more details. + diff --git a/LICENSE b/LICENSE new file mode 100644 index 0000000..1adda21 --- /dev/null +++ b/LICENSE @@ -0,0 +1,244 @@ +"iperf, Copyright (c) 2014-2023, The Regents of the University of California, +through Lawrence Berkeley National Laboratory (subject to receipt of any +required approvals from the U.S. Dept. of Energy).

It supports tuning of various parameters +related to timing, protocols, and buffers. For each test it reports +the measured throughput / bitrate, loss, and other parameters. + +This version, sometimes referred to as iperf3, is a redesign of an +original version developed at NLANR/DAST. iperf3 is a new +implementation from scratch, with the goal of a smaller, simpler code +base, and a library version of the functionality that can be used in +other programs. iperf3 also has a number of features found in other tools +such as nuttcp and netperf, but were missing from the original iperf. +These include, for example, a zero-copy mode and optional JSON output. +Note that iperf3 is *not* backwards compatible with the original iperf. + +Primary development for iperf3 takes place on Ubuntu Linux, FreeBSD, +and macOS. At this time, these are the only officially supported +platforms, however there have been some reports of success with +OpenBSD, NetBSD, Android, Solaris, and other Linux distributions. + +iperf3 is principally developed by ESnet / Lawrence Berkeley National +Laboratory. It is released under a three-clause BSD license. + +For more information see: https://software.es.net/iperf + +Source code and issue tracker: https://github.com/esnet/iperf + +Discussion forums: https://github.com/esnet/iperf/discussions + +Reporting security vulnerabilities: iperf@es.net + +Obtaining iperf3 +---------------- + +Downloads of iperf3 are available at: + + https://downloads.es.net/pub/iperf/ + +To check out the most recent code, clone the git repository at: + + https://github.com/esnet/iperf.git + +Building iperf3 +--------------- + +### Prerequisites: ### + +None. + +### Building ### + + ./configure; make; make install + +(Note: If configure fails, try running `./bootstrap.sh` first) + +Invoking iperf3 +--------------- + +iperf3 includes a manual page listing all of the command-line options. +The manual page is the most up-to-date reference to the various flags and parameters. + +For sample command line usage, see: + +https://fasterdata.es.net/performance-testing/network-troubleshooting-tools/iperf/ + +Using the default options, iperf is meant to show typical well +designed application performance. "Typical well designed application" +means avoiding artificial enhancements that work only for testing +(such as splice()'ing the data to /dev/null). iperf does also have +flags for "extreme best case" optimizations, but they must be +explicitly activated. + +These flags include: + + -Z, --zerocopy use a 'zero copy' sendfile() method of sending data + -A, --affinity n/n,m set CPU affinity + +Bug and Security Reports +------------------------ + +Before submitting a bug report, please make sure you're running the +latest version of the code, and confirm that your issue has not +already been fixed. Then submit to the iperf3 issue tracker on +GitHub: + +https://github.com/esnet/iperf/issues + +In your issue submission, please indicate the version of iperf3 and +what platform you're trying to run on (provide the platform +information even if you're not using a supported platform, we +*might* be able to help anyway). Exact command-line arguments will +help us recreate your problem. If you're getting error messages, +please include them verbatim if possible, but remember to sanitize any +sensitive information. + +If you have a question about usage or about the code, please do *not* +submit an issue. Please use one of the mailing lists for that. + +If you suspect there is a potential security issue, please contact the +developers at: + +iperf@es.net + +Relation to iperf 2.x +--------------------- + +Although iperf2 and iperf3 both measure network performance, +they are not compatible with each other. +The projects (as of mid-2021) are in active, but separate, development. +The continuing iperf2 development +project can be found at https://sourceforge.net/projects/iperf2/. + +Known Issues +------------ + +A set of known issues is maintained on the iperf3 Web pages: + +https://software.es.net/iperf/dev.html#known-issues + +Links +----- + +This section lists links to user-contributed Web pages regarding +iperf3.

Many thanks to @FuzzyStatic for providing access to a test + environment for diagnosing this issue (#692). + +iperf 3.4 2018-02-14 +-------------------- + +* Notable user-visible changes + + * The -A (set processor affinity) command-line flag is now supported + on Windows (#665). + + * iperf3 now builds on systems lacking a daemon(3) library call + (#369). + + * A bug in time skew checking under authentication was fixed (#674). + + * IPv6 flow labels now work correctly with multiple parallel streams + (#694). + + * The client no longer closes its control connection before sending + end-of-test statistics to the server (#677).

This condition primarily affected users on + Windows, but potentially improves robustness for all + platforms. (#659) + +* Notable developer-visible changes + +iperf 3.2 2017-06-26 +-------------------- + +* User-visible changes + + * Authentication via a username/password mechanism, coupled with a + public-key pair, is now an optional way of limiting access to an + iperf3 server (#517). + + * Ending statistics are less ambiguous for UDP and also now use + correct test durations for all protocols (#560, #238). Many fixes + have been made in statistics printing code, generally for + human-readable output (#562, #575, #252, #443, #236). + + * Several problems with the -F/--file options have been fixed. + Documentation has been improved to note some ways in which this + feature might not behave as expected (#588). + + * iperf3 now uses the correct "bitrate" phraseology rather than + "bandwidth" when describing measurement results. The --bandwidth + option has been renamed --bitrate, although --bandwidth is still + accepted for backwards compatibility (#583). + + * Application-level bandwidth pacing (--bitrate option) is now + checked every millisecond by default, instead of of every tenth of + a second, to provide smoother traffic behavior when using + application pacing (#460). The pacing can be tuned via the use of + the --pacing-timer option (#563). + + * A new --dscp option allows specifying the DSCP value to be used + for outgoing packets (#508). The TOS byte value is now printed in + the JSON output (#226). + + * Congestion window data on FreeBSD is now computed correctly (#465, + #475, #338). + + * The T/t suffixes for terabytes/terabits are now accepted for + quantities where suffixes are supported, such as --bandwidth + (#402). + + * Sanity checks for UDP send sizes have been added (#390), and + existing checks on the --window option have been improved (#557). + + * The TCP rttvar value is now available in the JSON output (#534), as are + the socket buffer sizes (#558). + + * Error handling and documentation have been improved for the + -f/--format options (#568). + + * A new --connect-timeout option on the client allows specifying a + length of time that the client will attempt to connect to the + server, in milliseconds (#216). + + * The hostname and current timestamp are no longer used in the + cookie used to associate the client and server. Instead, random + data is used. Note that iperf3 now requires the /dev/urandom + device (#582). + + * Prior versions of iperf3 doing UDP tests used to overcount packet + losses in the presence of packet reordering. This has been + (partially) fixed by try to not count the sequence number gaps + resulting from out-of-order packets as actual losses (#457). + + * iperf3 no longer prints results from very small intervals (10% of + the statistics reporting interval) at the end of the test run if + they contain no data. This can happen due to timing difference or + network queueing on the path between the client and server. This + is primarily a cosmetic change to prevent these fairly meaningless + intervals from showing up in the output (#278). + + * Compatibility note: Users running iperf3 3.2 or newer from the + bwctl utility will need to obtain version 1.6.3 or newer of bwctl. + Note that bwctl, a component of the perfSONAR toolkit, has been + deprecated in favor of pScheduler since the release of perfSONAR + 4.0. + +* Developer-visible changes + + * Various warnings and build fixes (#551, #564, #518, #597). + + * Some improvements have been made for increased compatibility on + IRIX (#368) and with C++ (#587). + + * cJSON has been updated to 1.5.2 (#573), bringing in a number of + bugfixes. + + * Some dead code has been removed. + +iperf 3.1.7 2017-03-06 +---------------------- + +iperf 3.1.7 is functionally identical to iperf 3.1.6. Its only +changes consist of updated documentation files and text in the RPM +spec file. + +iperf 3.1.6 2017-02-02 +---------------------- + +The release notes for iperf 3.1.6 describe changes, including bug +fixes and new functionality, made since iperf 3.1.5. + +* User-visible changes + + * Specifying --fq-rate or --no-fq-socket-pacing on a system where + these options are not supported now generate an error instead of a + warning. This change makes diagnosing issues related to pacing + more apparent. + + * Fixed a bug where two recently-added diagnostic messages spammed + the JSON output on UDP tests. + +iperf 3.1.5 2017-01-12 +---------------------- + +The release notes for iperf 3.1.5 describe changes, including bug +fixes and new functionality, made since iperf 3.1.4. + +Compatibility note: Fair-queueing is now specified differently in +iperf 3.1.5 than in prior versions (which include 3.1.3 and 3.1.4). + +Compatibility note: UDP tests may yield different results from all +prior versions of iperf3 (through 3.1.4) due to the new default UDP +sending size. + +* User-visible changes + + * The fair-queueing per-socket based pacing available on recent + Linux systems has been reimplemented with a different user + interface (#325, #467, #488). The --bandwidth command-line flag + now controls only the application-level pacing, as was the case in + iperf 3.1.2 and all earlier versions. Fair-queueing per-socket + based pacing is now controlled via a new --fq-rate command-line + flag. Note that TCP and UDP tests may use --bandwidth, --fq-rate, + both flags, or neither flag. SCTP tests currently support + --bandwidth only. The --no-fq-socket-pacing flag, which was + introduced in iperf 3.1.3, has now been deprecated, and is + equivalent to --fq-rate=0. iperf3 now reacts more gracefully if + --no-fq-socket-pacing or --fq-rate are specified on platforms that + don't support these options. + + For UDP tests, note that the default --bandwidth is 1 Mbps. Using + the fair-queueing-based pacing will probably require explicitly + setting both --bandwidth and --fq-rate, preferably to the same + value. (While setting different values for --bandwidth and + --fq-rate can certainly be done, the results can range from + entertaining to perplexing.) + + * iperf3 now chooses a more sane default UDP send size (#496, #498). + The former default (8KB) caused IP packet fragmentation on paths + having smaller MTUs (including any Ethernet network not configured + for jumbo frames). This could have effects ranging from increased + burstiness, to packet loss, to complete failure of the test. + iperf3 now attempts to use the MSS of the control connection to + determine a default UDP send size if no sending length was + explicitly specified with --length. + + * Several checks are now made when setting the socket buffer sizes + with the -w option, to verify that the settings have been applied + correctly. The results of these checks can been seen when the + --debug flag is specified. (#356) + + * A --forceflush flag has been added to flush the output stream + after every statistics reporting interval. + +* Developer-visible changes + + * A systemd service file has been added (#340, #430). + +iperf 3.1.4 2016-10-31 +---------------------- + +The release notes for iperf 3.1.4 describe changes, including bug +fixes and new functionality, made since iperf 3.1.3. + +* User-visible changes + + * On systems that support setting the congestion control algorithm, + iperf3 now keeps track of the congestion control algorithm and + print it in the JSON output in the members sender_tcp_congestion + and receiver_tcp_congestion (issue #461). A few bugs (probably + not user-visible) with setting the congestion control algorithm + were also fixed. + +* Developer-visible changes + + * Fixed a buffer overflow in the cJSON library (issue #466). It is + not believed that this bug created any security vulnerabilities in + the context of iperf3. + + * Travis CI builds are now enabled on this codeline (pull request #424). + + * Various bug fixes (issue #459, pull request #429, issue #388). + +iperf 3.1.3 2016-06-08 +---------------------- + +The release notes for iperf 3.1.3 describe changes, including bug +fixes and new functionality, made since iperf 3.1.2. + +* Security + + * Fixed a buffer overflow / heap corruption issue that could occur + if a malformed JSON string was passed on the control channel. In + theory, this vulnerability could be leveraged to create a heap + exploit. This issue, present in the cJSON library, was already + fixed upstream, so was addressed in iperf3 by importing a newer + version of cJSON (plus local ESnet modifications). Discovered and + reported by Dave McDaniel, Cisco Talos. Cross-references: + TALOS-CAN-0164, ESNET-SECADV-2016-0001, CVE-2016-4303. + +* User-visible changes + + * On supported platforms (recent Linux), iperf3 can use + fair-queueing-based per-socket pacing instead of its own + application-level pacing for the --bandwidth option. + Application-level pacing can be forced with the + -no-fq-socket-pacing flag. + + * A bug that could show negative loss counters with --udp and --omit + has been fixed (issue #412, pull request #414). + + * Error handling has been made slightly more robust. Also, the + iperf3 server will no longer exit after five consecutive errors, + but will only exit for certain types of errors that prevent it + from participating in any tests at all. + +* Developer-visible changes + + * Fixed the build on FreeBSD 11-CURRENT (issue #413). + + * Fixed various coding errors (issue #423, issue #425). + +iperf 3.1.2 2016-02-01 +---------------------- + +The release notes for iperf 3.1.2 describe changes, including bug +fixes and new functionality, made since iperf 3.1.1. + +* User-visible changes + + * Fixed a bug that caused nan values to be emitted (incorrectly) + into JSON, particularly at the end of UDP tests (issue #278). + + * Fixed a bug that caused the wrong value to be printed for + out-of-order UDP packets (issue #329). + + * Added a contrib/ directory containing a few submitted graphing + scripts. + +* Developer-visible changes + +iperf 3.1.1 2015-11-19 +---------------------- + +The release notes for iperf 3.1.1 describe changes and new +functionality in iperf 3.1.1, but not present in 3.1. + +* User-visible changes + + * Some markup fixes have been made in the manpages for Debian + compatibility (issue #291). + + * A bug where the -T title option was not being output correctly + in JSON output has been fixed (issue #292). + + * Argument handling for some command-line options has been improved + (issue #316). + +* Developer-visible changes + + * A regression with C++ compatibility in one of the iperf header + files has been fixed (issue #323). + +iperf 3.1 2015-10-16 +-------------------- + +The release notes for iperf 3.1 describe changes and new +functionality in iperf 3.1, but not present in 3.0.11 or any earlier +3.0.x release. + +* Selected user-visible changes + + * SCTP support has been added (with the --sctp flag), on Linux, + FreeBSD, and Solaris (issue #131). + + * Setting CPU affinity now works on FreeBSD. + + * Selection of TCP congestion now works on FreeBSD, and is now + called --congestion (the old --linux-congestion option works + but is now deprecated). + + * A new -I option for the server causes it to write a PID file, + mostly useful for daemon mode (issue #120). + + * A --logfile argument can now force all output to go to a file, + rather than to a file.

It +# sets the PTHREAD_LIBS output variable to the threads library and linker +# flags, and the PTHREAD_CFLAGS output variable to any special C compiler +# flags that are needed. (The user can also force certain compiler +# flags/libs to be tested by setting these environment variables.) +# +# Also sets PTHREAD_CC and PTHREAD_CXX to any special C compiler that is +# needed for multi-threaded programs (defaults to the value of CC +# respectively CXX otherwise). (This is necessary on e.g. AIX to use the +# special cc_r/CC_r compiler alias.) +# +# NOTE: You are assumed to not only compile your program with these flags, +# but also to link with them as well. For example, you might link with +# $PTHREAD_CC $CFLAGS $PTHREAD_CFLAGS $LDFLAGS ... $PTHREAD_LIBS $LIBS +# $PTHREAD_CXX $CXXFLAGS $PTHREAD_CFLAGS $LDFLAGS ... $PTHREAD_LIBS $LIBS +# +# If you are only building threaded programs, you may wish to use these +# variables in your default LIBS, CFLAGS, and CC: +# +# LIBS="$PTHREAD_LIBS $LIBS" +# CFLAGS="$CFLAGS $PTHREAD_CFLAGS" +# CXXFLAGS="$CXXFLAGS $PTHREAD_CFLAGS" +# CC="$PTHREAD_CC" +# CXX="$PTHREAD_CXX" +# +# In addition, if the PTHREAD_CREATE_JOINABLE thread-attribute constant +# has a nonstandard name, this macro defines PTHREAD_CREATE_JOINABLE to +# that name (e.g. PTHREAD_CREATE_UNDETACHED on AIX). +# +# Also HAVE_PTHREAD_PRIO_INHERIT is defined if pthread is found and the +# PTHREAD_PRIO_INHERIT symbol is defined when compiling with +# PTHREAD_CFLAGS. +# +# ACTION-IF-FOUND is a list of shell commands to run if a threads library +# is found, and ACTION-IF-NOT-FOUND is a list of commands to run it if it +# is not found. If ACTION-IF-FOUND is not specified, the default action +# will define HAVE_PTHREAD. +# +# Please let the authors know if this macro fails on any platform, or if +# you have any other suggestions or comments. This macro was based on work +# by SGJ on autoconf scripts for FFTW (http://www.fftw.org/) (with help +# from M. Frigo), as well as ac_pthread and hb_pthread macros posted by +# Alejandro Forero Cuervo to the autoconf macro repository.

+This is the first of a series of (maybe periodic?) updates about +iperf3 development: + +State of the iperf3 World, as seen from ESnet... +------------------------------------------------ + +iperf3 was originally written to be a "better", more maintainable +follow-on to iperf2. This was seen to be necessary to fill the +requirements for the perfSONAR project (http://www.perfsonar.net). + +In the past few years, iperf2 development has been restarted by Bob +McMahon of Broadcom. He (and other contributors) have fixed a number +of problems with iperf2 and added some new features +(https://sourceforge.net/projects/iperf2/). We're happy to observe +that iperf2 is once again under active development, and we have +started discussing ways in which these two projects could productively +interact. + +We note that iperf3 lacks several features found in iperf2, for +example multicast tests, bidirectional tests, multi-threading, and +official Windows support. Given the active state of iperf2 +development and maintenance, we feel that the needs of users requiring +such functionality are best met by using a recent version of iperf2 +instead of waiting for them to be backported or reimplemented in +iperf3. + +ESnet's main interest in iperf3 is for testing high-performance +Research and Education (R&E) networks, especially as a part of the +perfSONAR toolkit. iperf3 can be useful in other circumstances as +well, but high-speed R&E network performance testing will remain the +primary use case. (Much of iperf2's recent development +has focused on the use of UDP for end-to-end latency testing on a +broad range of platforms, although it too is useful for many other +testing scenarios.) + +iperf3 Support +-------------- + +We're trying to work down the support backlog for iperf3. To that +end, we've been aggressively triaging iperf3 issues in the issue +tracker on GitHub. Over the past several weeks, we've gone from about +180 open issues to less than 75. A number of these issues were user +questions, not bug reports or enhancement requests. We're now +discouraging the use of the iperf3 issue tracker for questions. +Instead we'd like users to either use the mailing list +(iperf-dev@google-groups.com) or to look to various question sites on +the Internet such as Stack Overflow (http://www.stackoverflow.com). + +We're happy to accept enhancement requests, although it should be +noted that ESnet's time commitments to iperf3 are somewhat limited and +we need to prioritize our work to match our own requirements. We have +begun using the "Help Wanted" label in the issue tracker on GitHub to +indicate requests we agree with (or at least don't object to), but +which we don't have the time to work on ourselves. These are good +candidates for someone in the community to work on and submit as a +pull request. + +Pull requests are still encouraged, as long as they're compatible with +ESnet's goals and requirements for iperf3. If you're contemplating a +code change that would have a major, fundamental change on the iperf3 +architecture, we strongly encourage discussion with the iperf3 +maintainers before doing a significant amount of work. + +Some of the above considerations are now documented in GitHub +templates that we've recently installed for new issues, pull requests, +and contribution guidelines. + +To make it easier for new users with common questions, we have created +a Frequently Asked Questions (FAQ) list, which is now available on the +iperf3 Web site, at: + +http://software.es.net/iperf/faq.html + +Future Plans +------------ + +In the near-term, we're planning another iperf3 release that will +include some recently added changes. Because some of the changes are +rather large, we're considering basing this release off the mainline +which would make it the first 3.2 release, rather than try to backport +these changes and make another "bugfix" 3.1 release. No decisions +have been made yet. + +The main changes (already on the master branch) are authentication +(#517), a more fine-grained pacing timer (#460), and some portability +fixes. We'd appreciate any testing and feedback that users in the +community could give on these. + +Thanks for your interest and support of iperf3, + +Bruce Mah +Software Engineering Group +ESnet diff --git a/docs/2017-06-06.txt b/docs/2017-06-06.txt new file mode 100644 index 0000000..e5a16cd --- /dev/null +++ b/docs/2017-06-06.txt @@ -0,0 +1,43 @@ +Subject: iperf3 status, June 2017 + +iperf 3.2 Release Plans +----------------------- + +We've done quite a bit of work the past few weeks getting the master +branch in shape to cut a new release, which will be the first of the +3.2.x series. These changes include fixes for a number of +long-standing bugs (such as some of the statistics computation, and +fixes for --file), as well as new features (for example optional +authentication and a configurable client connection timeout) and +general improvements (better timing for the --bitrate/--bandwidth +options). + +We'd like to encourage users in the community who are comfortable +compiling iperf3 from GitHub sources, to checkout / clone the iperf3 +master branch from GitHub and try it out in their environments. (No +tarballs will be produced until the official 3.2 release, although I'd +say we're basically in "release candidate" stage now.) + +There is a mostly-final set of release notes in the RELEASE_NOTES file +on master, so you can see what's new, changed, fixed, and so on. + +Assuming no serious problems, we're aiming for an official release in +mid- to late-June (2017!). + +iperf3 Support +-------------- + +After a lot of issue triage, we're down to 38 issues in the issue +tracker (plus three outstanding pull requests).

These issues are either open (indicating no solution +currently exists) or closed with the notation that no further attempts +to solve the problem are currently being made: + +* The ``-Z`` flag sometimes causes the iperf3 client to hang on OSX. + (Issue #129) + +* When specifying the TCP buffer size using the ``-w`` flag on Linux, + the Linux kernel automatically doubles the value passed in to + compensate for overheads. (This can be observed by using + iperf3's ``--debug`` flag.) However, CWND does not actually ramp up + to the doubled value, but only to about 75% of the doubled + value. Some part of this behavior is documented in the tcp(7) + manual page. + +* Although the ``-w`` flag is documented as setting the (TCP) window + size, it is also used to set the socket buffer size. This has been + shown to be helpful with high-bitrate UDP tests. + +* On some platforms (observed on at least one version of Ubuntu + Linux), it might be necessary to invoke ``ldconfig`` manually after + doing a ``make install`` before the ``iperf3`` executable can find + its shared library. (Issue #153) + +* The results printed on the server side at the end of a test do not + correctly reflect the client-side measurements. This is due to the + ordering of computing and transferring results between the client + and server. (Issue #293) + +* The server could have a very short measurement reporting interval at + the end of a test (particularly a UDP test), containing few or no + packets. This issue is due to an artifact of timing between the + client and server. (Issue #278) + +There are, of course, many other open and closed issues in the issue +tracker. + +Versioning +---------- + +iperf3 version numbers use (roughly) a `Semantic Versioning +`_ scheme, in which version numbers consist of +three parts: *MAJOR.MINOR.PATCH* + +The developers increment the: + +* *MAJOR* version when making incompatible API changes, + +* *MINOR* version when adding functionality in a backwards-compatible manner, and + +* *PATCH* version when making backwards-compatible bug fixes. + +Release Engineering Checklist +----------------------------- + +1. Update the ``README.md`` and ``RELNOTES.md`` files to be accurate. Make sure + that the "Known Issues" section of the ``README.md`` file and in this document + are up to date. + +2. Compose a release announcement. Most of the release announcement + can be written before tagging. Usually the previous version's + announcement can be used as a starting point. + +3. Preferably starting from a clean source tree (be sure that ``git + status`` emits no output), make the changes necessary to produce + the new version, such as bumping version numbers:: + + vi RELNOTES.md # update version number and release date + vi configure.ac # update version parameter in AC_INIT + vi src/iperf3.1 # update manpage revision date if needed + vi src/libiperf.3 # update manpage revision date if needed + git commit -a # commit changes to the local repository only + ./bootstrap.sh # regenerate configure script, etc. + git commit -a # commit changes to the local repository only + + # Assuming that $VERSION is the version number to be released... + ./make_release tag $VERSION # this creates a tag in the local repo + ./make_release tar $VERSION # create tarball and compute SHA256 hash + + These steps should be done on a platform with a relatively recent + version of autotools / libtools. Examples are MacOS / MacPorts or + FreeBSD. The versions of these tools in CentOS 6 are somewhat + older and probably should be avoided. + + The result will be a release artifact that should be used for + pre-testing. + +4. Stage the tarball (and a file containing the SHA256 hash) to the + download site. Currently this is located on ``downloads.es.net``. + +5. From another host, test the link in the release announcement by + downloading a fresh copy of the file and verifying the SHA256 + checksum. Checking all other links in the release announcement is + strongly recommended as well. + +6. Also verify (with file(1)) that the tarball is actually a gzipped + tarball. + +7. For extra points, actually try downloading, compiling, and + smoke-testing the results of the tarball on all supported + platforms. + +8. Plug the SHA256 checksum into the release announcement. + +9. PGP-sign the release announcement text using ``gpg --clearsign``. + The signed announcement will be sent out in a subsequent emails, + but could also be archived. Decoupling the signing from emailing + allows a signed release announcement to be resent via email or sent + by other, non-email means. + +10. At this point, the release can and should be considered + finalized. To commit the release-engineering-related changes to + GitHub and make them public, push them out thusly:: + + git push # Push version changes + git push --tags # Push the new tag to the GitHub repo + +11. Send the PGP-signed release announcement to the following + addresses. Remember to turn off signing in the MUA, if + applicable. Remember to check the source address when posting to + lists, as "closed" list will reject posting from all from + registered email addresses. + + * iperf-dev@googlegroups.com + + * iperf-users@lists.sourceforge.net + + * perfsonar-user@internet2.edu + + * perfsonar-developer@internet2.edu + + Note: Thunderbird sometimes mangles the PGP-signed release + announcement so that it does not verify correctly. This could be + due to Thunderbird trying to wrap the length of extremely long + lines (such as the SHA256 hash). Apple Mail and mutt seem to + handle this situation correctly. Testing the release announcement + sending process by sending a copy to oneself first and attempting + to verify the signature is highly encouraged. + +12. Update GitHub Releases with the current release notes. + +13. Update the iperf3 Project News section of the documentation site + to announce the new release (see ``docs/news.rst`` and + ``docs/conf.py`` in the source tree) and deploy a new build of the + documentation to GitHub Pages. + +14.

After spending some time trying to fix + iperf2's problems, ESnet decided by 2010 that a new, simpler tool + was needed, and began development of iperf3. The goal was make the + tool as simple as possible, so others could contribute to the code + base. For this reason, it was decided to make the tool single + threaded, and not worry about backwards compatibility with + iperf2. Many of the feature requests for iperf3 came from the + perfSONAR project (http://www.perfsonar.net). + + Then in 2014, Bob (Robert) McMahon from Broadcom restarted + development of iperf2 (See + https://sourceforge.net/projects/iperf2/). He fixed many of the + problems with iperf2, and added a number of new features similar to + iperf3. iperf2.0.8, released in 2015, made iperf2 a useful tool. iperf2's + current development is focused is on using UDP for latency testing, as well + as broad platform support. + + As of this writing (2017), both iperf2 and iperf3 are being actively + (although independently) developed. We recommend being familiar with + both tools, and use whichever tool’s features best match your needs. + + A feature comparison of iperf2, iperf3, and nuttcp is available at: + https://fasterdata.es.net/performance-testing/network-troubleshooting-tools/throughput-tool-comparision/ + +iperf3 parallel stream performance is much less than iperf2. Why? + iperf3 is single threaded, and iperf2 is multi-threaded. We + recommend using iperf2 for parallel streams. + If you want to use multiple iperf3 streams use the method described `here `_. + +I’m trying to use iperf3 on Windows, but having trouble. What should I do? + iperf3 is not officially supported on Windows, but iperf2 is. We + recommend you use iperf2. + + Some people are using Cygwin to run iperf3 in Windows, but not all + options will work. Some community-provided binaries of iperf3 for + Windows exist. + +How can I build a statically-linked executable of iperf3? + There are a number of reasons for building an iperf3 executable with + no dependencies on any shared libraries. Unfortunately this isn't + quite a straight-forward process. + + The steps below have nominally been tested on CentOS 7.4, but + can probably be adapted for use with other Linux distributions: + + #. If necessary, install the static C libraries; for CentOS this is + the ``glibc-static`` package. + + #. If OpenSSL is installed, be sure that its static libraries are + also installed, from the ``openssl-static`` package. + + #. Be sure that ``lksctp-*`` packages are not installed, because + as of this writing, there do not appear to be any static + libraries available for SCTP. + + #. Configure iperf3 thusly: ``configure "LDFLAGS=--static" + --disable-shared`` These options are necessary to disable the + generation of shared libraries and link the executable + statically. For iperf-3.8 or later, configuring as ``configure + --enable-static-bin`` is another, shorter way to accomplish + this. If SCTP is installed on the system it might also be + necessary to pass the ``--without-sctp`` flag at configure + time. + + #. Compile as normal. + + It appears that for FreeBSD (tested on FreeBSD 11.1-RELEASE), only + the last two steps are needed to produce a static executable. + +How can I build on a system that doesn't support profiled executables? + This problem has been noted by users attempting to build iperf3 for + Android systems, as well as some recent versions of macOS. + There are several workarounds. In order from least + effort to most effort: + + #. Beginning with iperf-3.8, profiled executables are actually not + built by default, so this question becomes somewhat moot. Pass + the ``--enable-profiling`` flag to ``configure`` to build + profiled executables. + + #. In iperf-3.6 and iperf-3.7, the ``--disable-profiling`` flag can be + passed to ``configure`` to disable the building of profiled + object files and the profiled executable. + + #. At the time the linking of the iperf3 profiled executable fails, + the "normal" iperf3 executable is probably already created. So if + you are willing to accept the error exit from the make process + (and a little bit of wasted work on the build host), you might + not need to do anything. + + #. After the configure step, there will be a definition in + ``src/Makefile`` that looks like this:: + + noinst_PROGRAMS = t_timer$(EXEEXT) t_units$(EXEEXT) t_uuid$(EXEEXT) \ + iperf3_profile$(EXEEXT) + + If you edit it to look like this, it will disable the build of the profiled iperf3:: + + noinst_PROGRAMS = t_timer$(EXEEXT) t_units$(EXEEXT) t_uuid$(EXEEXT) + + #. Similar to item 2 above, but more permanent...if you edit + ``src/Makefile.am`` and change the line reading like this:: + + noinst_PROGRAMS = t_timer t_units t_uuid iperf3_profile + + To look like this:: + + noinst_PROGRAMS = t_timer t_units t_uuid + + And then run ``./bootstrap.sh``, that will regenerate the project + Makefiles to make the exclusion of the profiled iperf3 executable + permanent (within that source tree). + +I'm seeing quite a bit of unexpected UDP loss. Why? + First, confirm you are using iperf 3.1.5 or higher. There was an + issue with the default UDP send size that was fixed in + 3.1.5. Second, try adding the flag ``-w2M`` to increase the socket + buffer sizes. That seems to make a big difference on some hosts. + +iperf3 UDP does not seem to work at bandwidths less than 100Kbps. Why? + You'll need to reduce the default packet length to get UDP rates of less that 100Kbps. Try ``-l100``. + +TCP throughput drops to (almost) zero during a test, what's going on? + A drop in throughput to almost zero, except maybe for the first + reported interval(s), may be related to problems in NIC TCP Offload, + which is used to offload TCP functionality to the NIC (see + https://en.wikipedia.org/wiki/TCP_offload_engine). The goal of TCP + Offload is to save main CPU performance, mainly in the areas of + segmentation and reassembly of large packets and checksum + computation. + + When TCP packets are sent with the "Don't Fragment" flag set, which + is the recommended setting, segmentation is done by the TCP stack + based on the reported next hop MSS in the ICMP Fragmentation Needed + message. With TCP Offload, active segmentation is done by the NIC on + the sending side, which is known as TCP Segmentation offload (TSO) + or in Windows as Large Send Offload (LSO). It seems that there are + TSO/LSO implementations which for some reason ignore the reported + MSS and therefore don’t perform segmentation. In these cases, when + large packets are sent, e.g. the default iperf3 128KB (131,072 + bytes), iperf3 will show that data was sent in the first interval, + but since the packets don’t get to the server, no ack is received + and therefore no data is sent in the following intervals. It may + happen that after certain timeout the main CPU will re-send the + packet by re-segmenting it, and in these cases data will get to the + server after a while. However, it seems that segmentation is not + automatically continued with the next packet, so the data transfer + rate be very low. + + The recommended solution in such a case is to disable TSO/LSO, at + least on the relevant port. See for example: + https://atomicit.ca/kb/articles/slow-network-speed-windows-10/. If + that doesn’t help then "Don't Fragment" TCP flag may be + disabled. See for example: + https://support.microsoft.com/en-us/help/900926/recommended-tcp-ip-settings-for-wan-links-with-a-mtu-size-of-less-than. However, + note that disabling the “Don’t Fragment” flag may cause other + issues. + + To test whether TSO/LSO may be the problem, do the following: + + * If different machine configurations are used for the client and + server, try the iperf3 reverse mode (``-R``). If TSO/LSO is only + enabled on the client machine, this test should succeed. + * Reduce the sending length to a small value that should not require + segmentation, using the iperf3 ``-l`` option, e.g. ``-l 512``. It + may also help to reduce the MTU by using the iperf3 ``-M`` option, + e.g. ``-M 1460``. + * Using tools like Wireshark, identify the required MSS in the ICMP + Fragmentation Needed messages (if reported). Run tests with the + ``-l`` value set to 2 times the MSS and then 4 times, 6 times, + etc. With TSO/LSO issue in each test the throughput should be + reduced more. It may help to increase the testing time beyond the + default 10 seconds to better see the behavior (iperf3 ``-t`` + option). + +What congestion control algorithms are supported? + On Linux, run this command to see the available congestion control + algorithms (note that some algorithms are packaged as kernel + modules, which must be loaded before they can be used):: + + /sbin/sysctl net.ipv4.tcp_available_congestion_control + + On FreeBSD, the equivalent command is:: + + /sbin/sysctl net.inet.tcp.cc.available + +I’m using the ``--logfile`` option. How do I see file output in real time? + Use the ``--forceflush`` flag. + +I'm using the --fq-rate flag, but it does not seem to be working. Why? + You need to add 'net.core.default_qdisc = fq' to /etc/sysctl.conf for that option to work. + +I'm having trouble getting iperf3 to work on Windows, Android, etc. Where can I get help? + iperf3 only supports Linux, FreeBSD, and OSX. For other platforms we recommend using iperf2. + +I managed to get a Windows executable built, but why do I get a BSOD on Windows 7? + There seems to be a bug in Windows 7 where running iperf3 from a + network filesystem can cause a system crash (in other words Blue + Screen of Death, or BSOD). This is a Windows bug addressed in kb2839149: + + https://support.microsoft.com/en-us/help/2839149/stop-error-0x00000027-in-the-rdbss-sys-process-in-windows-7-or-windows + + A hotfix is available under kb2732673: + + https://support.microsoft.com/en-us/help/2732673/-delayed-write-failed-error-message-when--pst-files-are-stored-on-a-ne + +Why can’t I run a UDP client with no server? + This is potentially dangerous, and an attacker could use this for a + denial of service attack.

Huh? + iperf3 uses a control connection between the client and server to + manage the start and end of each test. Sometimes the commands on + the control connection can be received and acted upon before all of + the test data has been processed. Thus the test ends with data + still in flight. This effect can be significant for short (a few + seconds) tests, but is probably negligible for longer tests. + +A file sent using the ``-F`` option got corrupted...what happened? + The ``-F`` option to iperf3 is not a file transfer utility. It's a + way of testing the end-to-end performance of a file transfer, + including filesystem and disk overheads. So while the test will + mimic an actual file transfer, the data stored to disk may not be + the same as what was sent. In particular, the file size will be + rounded up to the next larger multiple of the transfer block size, + and for UDP tests, iperf's metadata (containing timestamps and + sequence numbers) will overwrite the start of every UDP packet + payload. + +I have a question regarding iperf3...what's the best way to get help? + Searching on the Internet is a good first step. + http://stackoverflow.com/ has a number of iperf3-related questions + and answers, but a simple query into your favorite search engine can + also yield some results. + + There is a mailing list nominally used for iperf3 development, + iperf-dev@googlegroups.com. + + We discourage the use of the iperf3 issue tracker on GitHub for + support questions.

It + can test TCP, UDP, or SCTP throughput. To perform an iperf3 test the + user must establish both a server and a client. + + The iperf3 executable contains both client and server functionality. + An iperf3 server can be started using either of the -s or --server com- + mand-line parameters, for example: + + iperf3 -s + + iperf3 --server + + Note that many iperf3 parameters have both short (-s) and long + (--server) forms. In this section we will generally use the short form + of command-line flags, unless only the long form of a flag is avail- + able. + + By default, the iperf3 server listens on TCP port 5201 for connections + from an iperf3 client. A custom port can be specified by using the -p + flag, for example: + + iperf3 -s -p 5002 + + After the server is started, it will listen for connections from iperf3 + clients (in other words, the iperf3 program run in client mode). The + client mode can be started using the -c command-line option, which also + requires a host to which iperf3 should connect. The host can by speci- + fied by hostname, IPv4 literal, or IPv6 literal: + + iperf3 -c iperf3.example.com + + iperf3 -c 192.0.2.1 + + iperf3 -c 2001:db8::1 + + If the iperf3 server is running on a non-default TCP port, that port + number needs to be specified on the client as well: + + iperf3 -c iperf3.example.com -p 5002 + + The initial TCP connection is used to exchange test parameters, control + the start and end of the test, and to exchange test results. This is + sometimes referred to as the "control connection". The actual test + data is sent over a separate TCP connection, as a separate flow of UDP + packets, or as an independent SCTP connection, depending on what proto- + col was specified by the client. + + Normally, the test data is sent from the client to the server, and mea- + sures the upload speed of the client. Measuring the download speed + from the server can be done by specifying the -R flag on the client. + This causes data to be sent from the server to the client. + + iperf3 -c iperf3.example.com -p 5202 -R + + Results are displayed on both the client and server. There will be at + least one line of output per measurement interval (by default a mea- + surement interval lasts for one second, but this can be changed by the + -i option). Each line of output includes (at least) the time since the + start of the test, amount of data transferred during the interval, and + the average bitrate over that interval. Note that the values for each + measurement interval are taken from the point of view of the endpoint + process emitting that output (in other words, the output on the client + shows the measurement interval data for the client. + + At the end of the test is a set of statistics that shows (at least as + much as possible) a summary of the test as seen by both the sender and + the receiver, with lines tagged accordingly. Recall that by default + the client is the sender and the server is the receiver, although as + indicated above, use of the -R flag will reverse these roles. + + The client can be made to retrieve the server-side output for a given + test by specifying the --get-server-output flag. + + Either the client or the server can produce its output in a JSON struc- + ture, useful for integration with other programs, by passing it the -J + flag. Because the contents of the JSON structure are only completely + known after the test has finished, no JSON output will be emitted until + the end of the test. + + iperf3 has a (overly) large set of command-line options that can be + used to set the parameters of a test. They are given in the "GENERAL + OPTIONS" section of the manual page below, as well as summarized in + iperf3's help output, which can be viewed by running iperf3 with the -h + flag. + + GENERAL OPTIONS + -p, --port n + set server port to listen on/connect to to n (default 5201) + + -f, --format + [kmgtKMGT] format to report: Kbits/Mbits/Gbits/Tbits + + -i, --interval n + pause n seconds between periodic throughput reports; default is + 1, use 0 to disable + + -I, --pidfile file + write a file with the process ID, most useful when running as a + daemon. + + -F, --file name + Use a file as the source (on the sender) or sink (on the + receiver) of data, rather than just generating random data or + throwing it away. This feature is used for finding whether or + not the storage subsystem is the bottleneck for file transfers. + It does not turn iperf3 into a file transfer tool. The length, + attributes, and in some cases contents of the received file may + not match those of the original file. + + -A, --affinity n/n,m + Set the CPU affinity, if possible (Linux, FreeBSD, and Windows + only). On both the client and server you can set the local + affinity by using the n form of this argument (where n is a CPU + number). In addition, on the client side you can override the + server's affinity for just that one test, using the n,m form of + argument. Note that when using this feature, a process will + only be bound to a single CPU (as opposed to a set containing + potentially multiple CPUs). + + -B, --bind host[%dev] + bind to the specific interface associated with address host. If + an optional interface is specified, it is treated as a shortcut + for --bind-dev dev. Note that a percent sign and interface + device name are required for IPv6 link-local address literals. + + --bind-dev dev + bind to the specified network interface. This option uses + SO_BINDTODEVICE, and may require root permissions. (Available + on Linux and possibly other systems.) + + -V, --verbose + give more detailed output + + -J, --json + output in JSON format + + --logfile file + send output to a log file. + + --forceflush + force flushing output at every interval. Used to avoid buffer- + ing when sending output to pipe. + + --timestamps[=format] + prepend a timestamp at the start of each output line. By + default, timestamps have the format emitted by ctime(1). + Optionally, = followed by a format specification can be passed + to customize the timestamps, see strftime(3). If this optional + format is given, the = must immediately follow the --timestamps + option with no whitespace intervening. + + --rcv-timeout # + set idle timeout for receiving data during active tests. The + receiver will halt a test if no data is received from the sender + for this number of ms (default to 12000 ms, or 2 minutes). + + --snd-timeout # + set timeout for unacknowledged TCP data (on both test and con- + trol connections) This option can be used to force a faster test + timeout in case of a network partition during a test. The + required parameter is specified in ms, and defaults to the sys- + tem settings. This functionality depends on the TCP_USER_TIME- + OUT socket option, and will not work on systems that do not sup- + port it. + + -d, --debug + emit debugging output. Primarily (perhaps exclusively) of use + to developers. + + -v, --version + show version information and quit + + -h, --help + show a help synopsis + + + SERVER SPECIFIC OPTIONS + -s, --server + run in server mode + + -D, --daemon + run the server in background as a daemon + + -1, --one-off + handle one client connection, then exit. If an idle time is + set, the server will exit after that amount of time with no con- + nection. + + --idle-timeout n + restart the server after n seconds in case it gets stuck. In + one-off mode, this is the number of seconds the server will wait + before exiting. + + --server-bitrate-limit n[KMGT] + set a limit on the server side, which will cause a test to abort + if the client specifies a test of more than n bits per second, + or if the average data sent or received by the client (including + all data streams) is greater than n bits per second. The + default limit is zero, which implies no limit. The interval + over which to average the data rate is 5 seconds by default, but + can be specified by adding a '/' and a number to the bitrate + specifier. + + --rsa-private-key-path file + path to the RSA private key (not password-protected) used to + decrypt authentication credentials from the client (if built + with OpenSSL support). + + --authorized-users-path file + path to the configuration file containing authorized users cre- + dentials to run iperf tests (if built with OpenSSL support). + The file is a comma separated list of usernames and password + hashes; more information on the structure of the file can be + found in the EXAMPLES section. + + --time-skew-thresholdsecond seconds + time skew threshold (in seconds) between the server and client + during the authentication process. + + CLIENT SPECIFIC OPTIONS + -c, --client host[%dev] + run in client mode, connecting to the specified server. By + default, a test consists of sending data from the client to the + server, unless the -R flag is specified. If an optional inter- + face is specified, it is treated as a shortcut for --bind-dev + dev. Note that a percent sign and interface device name are + required for IPv6 link-local address literals. + + --sctp use SCTP rather than TCP (FreeBSD and Linux) + + -u, --udp + use UDP rather than TCP + + --connect-timeout n + set timeout for establishing the initial control connection to + the server, in milliseconds. The default behavior is the oper- + ating system's timeout for TCP connection establishment. Pro- + viding a shorter value may speed up detection of a down iperf3 + server. + + -b, --bitrate n[KMGT] + set target bitrate to n bits/sec (default 1 Mbit/sec for UDP, + unlimited for TCP/SCTP). If there are multiple streams (-P + flag), the throughput limit is applied separately to each + stream. You can also add a '/' and a number to the bitrate + specifier. This is called "burst mode". It will send the given + number of packets without pausing, even if that temporarily + exceeds the specified throughput limit. Setting the target + bitrate to 0 will disable bitrate limits (particularly useful + for UDP tests). This throughput limit is implemented internally + inside iperf3, and is available on all platforms. Compare with + the --fq-rate flag. This option replaces the --bandwidth flag, + which is now deprecated but (at least for now) still accepted. + + --pacing-timer n[KMGT] + set pacing timer interval in microseconds (default 1000 + microseconds, or 1 ms). This controls iperf3's internal pacing + timer for the -b/--bitrate option. The timer fires at the + interval set by this parameter. Smaller values of the pacing + timer parameter smooth out the traffic emitted by iperf3, but + potentially at the cost of performance due to more frequent + timer processing. + + --fq-rate n[KMGT] + Set a rate to be used with fair-queueing based socket-level pac- + ing, in bits per second. This pacing (if specified) will be in + addition to any pacing due to iperf3's internal throughput pac- + ing (-b/--bitrate flag), and both can be specified for the same + test. Only available on platforms supporting the SO_MAX_PAC- + ING_RATE socket option (currently only Linux). The default is + no fair-queueing based pacing. + + --no-fq-socket-pacing + This option is deprecated and will be removed. It is equivalent + to specifying --fq-rate=0. + + -t, --time n + time in seconds to transmit for (default 10 secs) + + -n, --bytes n[KMGT] + number of bytes to transmit (instead of -t) + + -k, --blockcount n[KMGT] + number of blocks (packets) to transmit (instead of -t or -n) + + -l, --length n[KMGT] + length of buffer to read or write. For TCP tests, the default + value is 128KB. In the case of UDP, iperf3 tries to dynamically + determine a reasonable sending size based on the path MTU; if + that cannot be determined it uses 1460 bytes as a sending size. + For SCTP tests, the default size is 64KB. + + --cport port + bind data streams to a specific client port (for TCP and UDP + only, default is to use an ephemeral port) + + -P, --parallel n + number of parallel client streams to run. Note that iperf3 is + single threaded, so if you are CPU bound, this will not yield + higher throughput. + + -R, --reverse + reverse the direction of a test, so that the server sends data + to the client + + --bidir + test in both directions (normal and reverse), with both the + client and server sending and receiving data simultaneously + + -w, --window n[KMGT] + set socket buffer size / window size. This value gets sent to + the server and used on that side too; on both sides this option + sets both the sending and receiving socket buffer sizes. This + option can be used to set (indirectly) the maximum TCP window + size. Note that on Linux systems, the effective maximum window + size is approximately double what is specified by this option + (this behavior is not a bug in iperf3 but a "feature" of the + Linux kernel, as documented by tcp(7) and socket(7)). + + -M, --set-mss n + set TCP/SCTP maximum segment size (MTU - 40 bytes) + + -N, --no-delay + set TCP/SCTP no delay, disabling Nagle's Algorithm + + -4, --version4 + only use IPv4 + + -6, --version6 + only use IPv6 + + -S, --tos n + set the IP type of service. The usual prefixes for octal and hex + can be used, i.e. 52, 064 and 0x34 all specify the same value. + + --dscp dscp + set the IP DSCP bits. Both numeric and symbolic values are + accepted. Numeric values can be specified in decimal, octal and + hex (see --tos above). To set both the DSCP bits and the ECN + bits, use --tos. + + -L, --flowlabel n + set the IPv6 flow label (currently only supported on Linux) + + -X, --xbind name + Bind SCTP associations to a specific subset of links using + sctp_bindx(3). The --B flag will be ignored if this flag is + specified. Normally SCTP will include the protocol addresses of + all active links on the local host when setting up an associa- + tion. Specifying at least one --X name will disable this behav- + iour. This flag must be specified for each link to be included + in the association, and is supported for both iperf servers and + clients (the latter are supported by passing the first --X argu- + ment to bind(2)). Hostnames are accepted as arguments and are + resolved using getaddrinfo(3). If the --4 or --6 flags are + specified, names which do not resolve to addresses within the + specified protocol family will be ignored. + + --nstreams n + Set number of SCTP streams. + + -Z, --zerocopy + Use a "zero copy" method of sending data, such as sendfile(2), + instead of the usual write(2). + + -O, --omit n + Perform pre-test for N seconds and omit the pre-test statistics, + to skip past the TCP slow-start period. + + -T, --title str + Prefix every output line with this string. + + --extra-data str + Specify an extra data string field to be included in JSON out- + put. + + -C, --congestion algo + Set the congestion control algorithm (Linux and FreeBSD only). + An older --linux-congestion synonym for this flag is accepted + but is deprecated. + + --get-server-output + Get the output from the server. The output format is determined + by the server (in particular, if the server was invoked with the + --json flag, the output will be in JSON format, otherwise it + will be in human-readable format). If the client is run with + --json, the server output is included in a JSON object; other- + wise it is appended at the bottom of the human-readable output. + + --udp-counters-64bit + Use 64-bit counters in UDP test packets. The use of this option + can help prevent counter overflows during long or high-bitrate + UDP tests. Both client and server need to be running at least + version 3.1 for this option to work. It may become the default + behavior at some point in the future. + + --repeating-payload + Use repeating pattern in payload, instead of random bytes. The + same payload is used in iperf2 (ASCII '0..9' repeating). It + might help to test and reveal problems in networking gear with + hardware compression (including some WiFi access points), where + iperf2 and iperf3 perform differently, just based on payload + entropy. + + --dont-fragment + Set the IPv4 Don't Fragment (DF) bit on outgoing packets. Only + applicable to tests doing UDP over IPv4. + + --username username + username to use for authentication to the iperf server (if built + with OpenSSL support). The password will be prompted for inter- + actively when the test is run. Note, the password to use can + also be specified via the IPERF3_PASSWORD environment variable. + If this variable is present, the password prompt will be + skipped. + + --rsa-public-key-path file + path to the RSA public key used to encrypt authentication cre- + dentials (if built with OpenSSL support) + + + EXAMPLES + Authentication - RSA Keypair + The authentication feature of iperf3 requires an RSA public keypair. + The public key is used to encrypt the authentication token containing + the user credentials, while the private key is used to decrypt the + authentication token. The private key must be in PEM format and addi- + tionally must not have a password set. The public key must be in PEM + format and use SubjectPrefixKeyInfo encoding. An example of a set of + UNIX/Linux commands using OpenSSL to generate a correctly-formed key- + pair follows: + + > openssl genrsa -des3 -out private.pem 2048 + > openssl rsa -in private.pem -outform PEM -pubout -out public.pem + > openssl rsa -in private.pem -out private_not_protected.pem -out- + form PEM + + After these commands, the public key will be contained in the file pub- + lic.pem and the private key will be contained in the file pri- + vate_not_protected.pem. + + Authentication - Authorized users configuration file + A simple plaintext file must be provided to the iperf3 server in order + to specify the authorized user credentials. The file is a simple list + of comma-separated pairs of a username and a corresponding password + hash. The password hash is a SHA256 hash of the string "{$user}$pass- + word". The file can also contain commented lines (starting with the # + character). An example of commands to generate the password hash on a + UNIX/Linux system is given below: + + > S_USER=mario S_PASSWD=rossi + > echo -n "{$S_USER}$S_PASSWD" | sha256sum | awk '{ print $1 }' + + An example of a password file (with an entry corresponding to the above + username and password) is given below: + > cat credentials.csv + # file format: username,sha256 + mario,bf7a49a846d44b454a5d11e7acfaf13d138bbe0b7483aa3e050879700572709b + + + + AUTHORS + A list of the contributors to iperf3 can be found within the documenta- + tion located at https://software.es.net/iperf/dev.html#authors. + + + SEE ALSO + libiperf(3), https://software.es.net/iperf + + + + ESnet September 2022 IPERF3(1) + + +The iperf3 manual page will typically be installed in manual +section 1. diff --git a/docs/news.rst b/docs/news.rst new file mode 100644 index 0000000..b0bcfac --- /dev/null +++ b/docs/news.rst @@ -0,0 +1,469 @@ +iperf3 Project News +=================== + +2023-09-14: iperf-3.15 released +-------------------------------- +| URL: https://downloads.es.net/pub/iperf/iperf-3.15.tar.gz +| SHA256: ``bdb77c11f72bce90214883159577fa24412013e62b2083cf5f54391d79b1d8ff`` + +iperf 3.15 fixes that could cause an iperf3 server process to hang +waiting for input on the control connection.

+.TH IPERF3 1 "November 2023" ESnet "User Manuals" +.SH NAME +iperf3 \- perform network throughput tests +.SH SYNOPSIS +.B iperf3 -s [ +.I options +.B ] +.br +.B iperf3 -c +.I server +.B [ +.I options +.B ] + +.SH DESCRIPTION +iperf3 is a tool for performing network throughput measurements. +It can test TCP, UDP, or SCTP throughput. +To perform an iperf3 test the user must establish both a server and a +client. +.PP +The iperf3 executable contains both client and server functionality. +An iperf3 server can be started using either of the -s or +--server command-line parameters, for example: +.IP +\fCiperf3 -s\fR +.IP +\fCiperf3 --server \fR +.PP +Note that many iperf3 parameters have both short (-s) and long +(--server) forms. +In this section we will generally use the short form of command-line +flags, unless only the long form of a flag is available. +.PP +By default, the iperf3 server listens on TCP port 5201 for connections +from an iperf3 client. +A custom port can be specified by using the -p flag, for +example: +.IP +\fCiperf3 -s -p 5002\fR +.PP +After the server is started, it will listen for connections from +iperf3 clients (in other words, the iperf3 program run in client +mode). +The client mode can be started using the -c command-line option, +which also requires a host to which iperf3 should connect. +The host can by specified by hostname, IPv4 literal, or IPv6 literal: +.IP +\fCiperf3 -c iperf3.example.com\fR +.IP +\fCiperf3 -c 192.0.2.1\fR +.IP +\fCiperf3 -c 2001:db8::1\fR +.PP +If the iperf3 server is running on a non-default TCP port, that port +number needs to be specified on the client as well: +.IP +\fCiperf3 -c iperf3.example.com -p 5002\fR +.PP +The initial TCP connection is used to exchange test parameters, +control the start and end of the test, and to exchange test results. +This is sometimes referred to as the "control connection". +The actual test data is sent over a separate TCP connection, as a +separate flow of UDP packets, or as an independent SCTP connection, +depending on what protocol was specified by the client. +.PP +Normally, the test data is sent from the client to the server, and +measures the upload speed of the client. +Measuring the download speed from the server can be done by specifying +the -R flag on the client. +This causes data to be sent from the server to the client. +.IP +\fCiperf3 -c

The elements + * are singly linked for minimum space and pointer manipulation overhead at + * the expense of O(n) removal for arbitrary elements. New elements can be + * added to the list after an existing element or at the head of the list. + * Elements being removed from the head of the list should use the explicit + * macro for this purpose for optimum efficiency. A singly-linked list may + * only be traversed in the forward direction. Singly-linked lists are ideal + * for applications with large datasets and few or no removals or for + * implementing a LIFO queue. + * + * A list is headed by a single forward pointer (or an array of forward + * pointers for a hash table header).

New elements can be added to the list before + * or after an existing element or at the head of the list.
