This page contains some guidelines for filing issues, pull requests, and other sorts of interactions with the iperf3 project. These are guidelines and not hard rules, and it is intended that common sense and good judgement will prevail. ## Support iperf3 is officially supported on Linux (various distributions), FreeBSD, and macOS. Support may be provided on a best-effort basis to other UNIX-like platforms. We cannot provide support for building and/or running iperf3 on Windows, iOS, or Android. Before asking for help, please use your favorite search engine or questions site (such as Stack Overflow) to see if your question might have been asked (and maybe even answered) before. https://fasterdata.es.net/ has some information on the use of various bandwidth measurement tools, including iperf3. The iperf3 documentation Web site at http://software.es.net/iperf/ contains various bits of helpful information, including a list of [frequently-asked questions](http://software.es.net/iperf/faq.html). We specifically discourage the use of the issue tracker on the iperf3 GitHub project page for asking questions. Questions posted in the form of issues may go unanswered. Please use a questions site such as [Stack Overflow](http://www.stackoverflow.com) to ask questions of the community or alternatively use the iperf3 mailing list at iperf-dev@googlegroups.com (posting requires joining the list). ## Code If you have improvements or bugfixes to make to iperf3, we'd love to hear from you. We prefer changes to be submitted in the form of pull requests on GitHub, although we can (probably) accept simple patches as well. If in doubt, ask. Before making any submission to the iperf3 project (whether it be code or documentation), we urge you to consult the iperf3 license, in particular the section quoted below: ``` You are under no obligation whatsoever to provide any bug fixes, patches, or upgrades to the features, functionality or performance of the source code ("Enhancements") to anyone; however, if you choose to make your Enhancements available either publicly, or directly to Lawrence Berkeley National Laboratory, without imposing a separate written license agreement for such Enhancements, then you hereby grant the following license: a non-exclusive, royalty-free perpetual license to install, use, modify, prepare derivative works, incorporate into other computer software, distribute, and sublicense such enhancements or derivative works thereof, in binary and source code form. ``` If you're considering changes that will have an architectural impact, we strongly encourage discussing them with the iperf3 maintainers before doing a significant amount of work on the code. We might be able to provide some guidance. Also, we're more likely to accept a submission if if it doesn't involve rewriting large sections of the code. Even if you're going to fork the code and maintain your own changes privately (which you're perfectly welcome to do) we might able to give you guidance so that future iperf3 changes won't conflict with your work. ## Conduct We expect that iperf3 interactions via the issue tracker, mailing lists, and so forth will be conducted civilly. Language that is deemed appropriate or abusive may be removed, and we reserve the right to ban users from accessing the project for repeated offense. iperf-3.9/.github/ISSUE_TEMPLATE.md000066400000000000000000000024561371560553300165560ustar00rootroot00000000000000_NOTE: The iperf3 issue tracker is for registering bugs, enhancement requests, or submissions of code. It is not a means for asking questions about building or using iperf3. Those are best directed towards the iperf3 mailing list at iperf-dev@googlegroups.com or question sites such as Stack Overflow (http://www.stackoverflow.com/).

This file is free documentation; the Free Software Foundation gives unlimited permission to copy, distribute and modify it. Basic Installation ================== These are generic installation instructions. The `configure' shell script attempts to guess correct values for various system-dependent variables used during compilation. 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. iperf-3.9/LICENSE000066400000000000000000000270651371560553300135210ustar00rootroot00000000000000"iperf, Copyright (c) 2014-2020, 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 CentOS 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 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 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. Relation to iperf 2.x --------------------- Note that iperf2 is no longer being developed by its original maintainers. However, beginning in 2014, another developer began fixing bugs and enhancing functionality, and generating releases of iperf2. Both projects (as of late 2017) are currently being developed actively, but independently. The continuing iperf2 development project can be found at https://sourceforge.net/projects/iperf2/. iperf3 contains a number of options and functions not present in iperf2. In addition, some flags are changed from their iperf2 counterparts: -C, --linux-congestion set congestion control algorithm (Linux only) (-Z in iperf2) --bidir bidirectional testing mode (-d in iperf2) Some iperf2 options are not available in iperf3: -r, --tradeoff Do a bidirectional test individually -T, --ttl time-to-live, for multicast (default 1) -x, --reportexclude [CDMSV] exclude C(connection) D(data) M(multicast) S(settings) V(server) reports -y, --reportstyle C report as a Comma-Separated Values Also removed is the ability to set the options via environment variables. 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.

An optional argument to this flag, which is a format specification to strftime(3), allows for custom timestamp formats (#909, #1028). * A --server-bitrate-limit flag has been added as a server-side command-line argument. It allows a server to enforce a maximum throughput rate; client connections that specify a higher bitrate or exceed this bitrate during a test will be terminated. The bitrate is expressed in bits per second, with an optional trailing slash and integer count that specifies an averaging interval over which to enforce the limit (#999). * A bug that caused increased CPU usage with the --bidir option has been fixed (#1011). * Notable developer-visible changes * Fixed various minor memory leaks (#1023). iperf 3.8.1 2020-06-10 ---------------------- * Notable user-visible changes * A regression with "make install", where the libiperf shared library files were not getting installed, has been fixed (#1013 / #1014). iperf 3.8 2020-06-08 -------------------- * Notable user-visible changes * Profiled libraries and binaries are no longer built by default (#950). * A minimal Dockerfile has been added (#824). * A bug with burst mode and unlimited rate has been fixed (#898). * Configuring with the --enable-static-bin flag will now cause a statically-linked iperf3 binary to be built (#989). * Configuring with the --without-sctp flag will now prevent SCTP from being auto-detected (#1008). This flag allows building a static binary (see above item) on a CentOS system with SCTP installed, because no static SCTP libraries are available. * Clock skew between the iperf3 client and server will no longer skew the computation of jitter during UDP tests (#842 / #990). * A possible buffer overflow in the authentication feature has been fixed. This was only relevant when configuration authentication using the libiperf3 API, and did not affect command-line usage. Various other improvements and fixes in this area were also made (#996). * Notable developer-visible changes * The embedded version of cJSON has been updated to 1.7.13 (#978). * Some server authentication functions have been added to the API (#911). * API access has been added to the connection timeout parameter (#1001). * Tests for some authentication functions have been added. * Various compiler errors and warnings have been fixed. iperf 3.7 2019-06-21 -------------------- * Notable user-visible changes * Support for simultaneous bidirectional tests with the --bidir flag (#201/#780). * Use POSIX standard clock_gettime(3) interface for timekeeping where available (#253/#738). * Passwords for authentication can be provided via environment variable (#815). * Specifying --repeating-payload and --reverse now works (#867). * Failed authentication doesn't count for --one-off (#864/#877). * Several memory leaks related to authenticated use were fixed (#881/#888). * The delay for tearing down the control connection for the default timed tests has been increased, to more gracefully handle high-delay paths (#751/#859). * Notable developer-visible changes * Various improvements to the libiperf APIs (#767, #775, #869, #870, #871) * Fixed build behavior when OpenSSL is absent (#854). * Portability fixes (#821/#874). iperf 3.6 2018-06-25 -------------------- * Notable user-visible changes * A new --extra-data option can be used to fill in a user-defined string field that appears in JSON output. (#600 / #729) * A new --repeating-payload option makes iperf3 use a payload pattern similar to that used by iperf2, which could help in recreating results that might be affected by payload entropy (for example, compression). (#726) * -B now works properly with SCTP tests. (#678 / #715) * A compile fix for Solaris 10 was added. (#711) * Some minor bug fixes for JSON output. In particular, warnings for debug and/or verbose modes with --json output (#737) and a fix for JSON output on CentOS 6 (#727 / #744). * software.es.net and downloads.es.net now support HTTPS, so URLs in documentation that refer to those two hosts now use https:// instead of http:// URLs. (#759) * Notable developer-visible changes * Functions related to authenticated iperf3 connections have been exposed via libiperf. (#712 / #713) * The ToS byte is now exposed in the libiperf API. (#719) iperf 3.5 2018-03-02 -------------------- * Notable user-visible changes * iperf3 no longer counts data received after the end of a test in the bytecounts. This fixes a bug that could, under some conditions, artificially inflate the transfer size and measured bitrate. This bug was most noticeable on reverse direction transfers on short tests over high-latency or buffer-bloated paths. 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 fixes a regression introduced in iperf-3.2. * Sending output to stdout now makes errors go to stderr, as per UNIX convention (#695). * A server side crash in verbose output with a client running multiple parallel connections has been fixed (#686). * The --cport option can now be specified without the --bind option. Using the --cport option on Linux can eliminate a problem with ephemeral port number allocation that can make multi-stream iperf3 tests perform very poorly on LAGG links. Also, the --cport option now works on SCTP tests (#697). * Notable developer-visible changes * iperf3 now builds on (some) macOS systems older than 10.7 (#607). * Some unused code and header inclusions were eliminated (#667, #668). Also some code was cleaned up to eliminate (or at least reduce) compiler warnings (#664, #671). iperf 3.3 2017-10-31 -------------------- * Notable user-visible changes * iperf3 can now be built --without-openssl on systems where OpenSSL is present (#624, #633). * A bug with printing very large numbers has been fixed (#642). * A bug where the server would, under certain circumstances, halt a test after exactly fifteen seconds has been fixed (#645). * The --tos parameter is no longer "sticky" between tests when doing --reverse tests (#639). * The authentication token on the server is properly reset between tests (#650). * A bug that could cause iperf3 to overwrite the PID file of an already-existing iperf3 process has been fixed (#623). * iperf3 will now ignore nonsensical TCP MSS values (from the TCP control connection) when trying to determine a reasonable block size for UDP tests. 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). * Compatiblity 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. This is especially useful when running an iperf3 server in daemon mode (issue #119). * Various compatibility fixes for Android (issue #184, issue #185), iOS (issue #288), NetBSD (issue #248), Solaris (issue #175, issue #178, issue #180, issue #211), vxWorks (issue #268). * A --udp-counters-64bit flag has been added to support very long-running UDP tests, which could cause a counter to overflow (issue #191). * A --cport option to specify the client-side port has been added (issue #207, issue #209, issue #239). * Some calculation errors with the -O feature have been fixed (issue #236). * A potential crash in the iperf3 server has been fixed (issue #257, issue #258). * Many miscellaneous bug fixes. * Selected developer-visible changes * Consumers of libiperf can now get the JSON output for a just-completed test (issue #147). * Detection of various optional features has been improved to check for the presence or absence of platform functionality, not the name of platforms. * Out-of-tree builds now work (issue #265). iperf 3.0.11 2015-01-09 ----------------------- * User-visible changes * Added -1 / --one-off flag, which causes the iperf3 server to process one client connection and then exit. Intended primarily for bwctl integration (issue #230). * Added various minor bug fixes (issues #231, #232, #233). * Added 30-second timeout for UDP tests if unable to establish UDP connectivity between sender and receiver (issue #222). iperf 3.0.10 2014-12-16 ----------------------- * User-visible changes * Fixed the build on MacOS X Yosemite (issue #213). * UDP tests now honor the -w option for setting the socket buffer sizes (issue #219). * Developer-visible changes * Added an RPM spec file plus functionality to fill in the version number. * Fixed potential filename collision with a system header (issue #203). iperf 3.0.9 2014-10-14 ---------------------- * User-visible changes * Fixed a series of problems that came from attempting a UDP test with a pathologically large block size. This put the server into an odd state where it could not accept new client connections. This in turn caused subsequent client connections to crash when interrupted (issue #212). * Developer-visible changes * None. iperf 3.0.8 2014-09-30 ---------------------- * User-visible changes * Updated license and copyright verbage to confirm to LBNL Tech Transfer requirements. No substantive changes; license remains the 3-clause BSD license. * Developer-visible changes * None. iperf 3.0.7 2014-08-28 ---------------------- * User-visible changes * A server bug where new connections from clients could disrupt running tests has been fixed (issue #202). * Rates now consistently use 1000-based prefixes (K, M, G), where sizes of objects now consistently use 1024-based prefixes (issue #173). * UDP tests with unlimited bandwidth are now supported (issue #170). * An interaction between the -w and -B options, which kept them from working when used together, has been fixed (issue #193). * Developer-visible changes iperf 3.0.6 2014-07-28 ---------------------- * User-visible changes * Several bugs that kept the -B option from working in various circumstances have been fixed (issue #193). * Various compatibility fixes for OpenBSD (issue #196) and Solaris (issue #177). * Developer-visible changes * The {get,set}_test_bind_address API calls have been added to expose the -B functionality to API consumers (issue #197). iperf 3.0.5 2014-06-16 ---------------------- * User-visible changes * Erroneous output when doing --json output has been fixed (this problem was caused by an attempt to fix issue #158). * The maximum test running time has been increased from one hour to one day (issue #166). * Project documentation has been moved to GitHub Pages at this URL: http://software.es.net/iperf/. * A bug that caused CPU time to be computed incorrectly on FreeBSD has been fixed. * A timing issue which caused measurement intervals to be wrong with TCP tests on lossy networks has been fixed (issue #125). * Newer versions of autoconf / automake / libtool are now used by default (issue #161). * JSON output now indicates whether the test was run in --reverse mode (issue #167). * It is now possible to get (most of) the server-side output at the client by using the --get-server-output flag (issue #160). * Developer-visible changes * automake/autoconf/libtool have been updated to more recent versions. AM_MAINTAINER_MODE is now used to avoid requiring these tools at build-time. iperf 3.0.4 was not released ---------------------------- iperf 3.0.3 2014-03-26 ---------------------- * User-visible changes * Due to several oversights, the source code archive for iperf 3.0.2 was distributed as an uncompressed tarball, despite having an extension (".tar.gz") that indicated it was compressed. The release generation procedure has been changed to avoid this problem going forward. * Summary structures in the JSON output are now included, even if there is only one stream. This change makes consuming the JSON output easier and more consistent (issue #151). * A possible buffer overflow in iperf_error.c has been fixed (issue #155). * Developer-visible changes * Example programs now build correctly, after having been broken in the 3.0.2 release (issue #152). iperf 3.0.2 2014-03-10 ---------------------- * User-visible changes * The iperf3 project has been moved to GitHub, and various URLs in documentation files have been changed to point there. * iperf3 now builds on Linux systems that do not support TCP_CONGESTION. Most notably this allows iperf3 to work on CentOS 5. * An abort on MacOS 10.9 has been fixed (issue #135). * Added -I flag for the server to write a PID file, mostly useful for daemon mode (issue #120). * A bug that could break some TCP tests on FreeBSD has been fixed. * TCP snd_cwnd output is now printed by default on Linux (issue #99). * In JSON output, the --title string no longer has a colon and two spaces appended (issue #139). * A buffer for holding formatted numeric values is now properly-sized so that output is not truncated (issue #142). * Developer-visible changes * Some memory leaks have been fixed. * A -d flag enables debugging output. * A .gitignore file has been added. * libtoolize is now invoked correctly from the bootstrap.sh script. * The test unit format can now be set from the API (issue #144). * libiperf is now built as both shared and static libraries. * In the JSON output, the "connection" structures are now stored as an array in the "start" block, instead of overwriting each other. While technically an incompatible API change, the former behavior generated unusable JSON. iperf 3.0.1 2014-01-10 ---------------------- * Added the following new flags -D, --daemon run server as a daemon -L, --flowlabel set IPv6 flow label (Linux only) -C, --linux-congestion set congestion control algorithm (Linux only) -k, --blockcount #[KMG] number of blocks (packets) to transmit (instead of -t or -n) * Bug fixes iperf 3.0-RC5 2013-11-15 ------------------------ * Added the following new flags -F, --file name xmit/recv the specified file -A, --affinity n/n,m set CPU affinity (Linux only) -J, --json output in JSON format -Z, --zerocopy use a 'zero copy' method of sending data -O, --omit N omit the first n seconds -T, --title str prefix every output line with this string * more useful information in 'verbose' mode * Many bug fixes iperf 3.0b4 2010-08-02 ---------------------- * Added support for binding to a specific interface (-B) * Added support for IPv6 mode (-6) * Setting TCP window size (-w) is now supported * Updates to iperf_error * Added new errors * Should generate more relavent messages * Stream list now managed by queue.h macros * Test structures are now kept intact after a test is run (for API users) * Improved interval timer granularity * Support for decimal values * Many bug fixes iperf 3.0b3 2010-07-23 ---------------------- * Better error handling * All errors now handled with iperf_error() * All functions that can return errors return NULL or -1 on error and set i_errno appropriately * Iperf API intruduced * Support for adding new protocols * Added support for callback functions * on_connect - executes after a connection is made to the server * on_new_stream - executes after a new stream is created * on_test_start - executes right before the test begins * on_test_finish - executes after the test is finished * Added early support for verbose mode (-V) iperf 3.0b2 2010-07-15 ---------------------- * UDP mode now supported * Support for setting bandwidth (-b) * Parallel UDP stream support * Reverse mode UDP support * Support for setting TCP_NODELAY (-N), disabling Nagle's Algorithm * Support for setting TCP MSS (-M) * Note: This feature is still in development. It is still very buggy. iperf 3.0b1 2010-07-08 ---------------------- * TCP control socket now manages messages between client and server * Dynamic server (gets test parameters from client) * Server can now set test options dynamically without having to restart. * Currently supported options: -l, -t, -n, -P, -R * Future options: -u, -b, -w, -M, -N, -I, -T, -Z, -6 * Results exchange * Client can now see server results (and vice versa) * Reverse mode (-R) * Server sends, client receives iperf-3.9/aclocal.m4000066400000000000000000013335261371560553300143570ustar00rootroot00000000000000# generated automatically by aclocal 1.16.2 -*- Autoconf -*- # Copyright (C) 1996-2020 Free Software Foundation, Inc. # This file is free software; the Free Software Foundation # gives unlimited permission to copy and/or distribute it, # with or without modifications, as long as this notice is preserved. # This program is distributed in the hope that it will be useful, # but WITHOUT ANY WARRANTY, to the extent permitted by law; without # even the implied warranty of MERCHANTABILITY or FITNESS FOR A # PARTICULAR PURPOSE. m4_ifndef([AC_CONFIG_MACRO_DIRS], [m4_defun([_AM_CONFIG_MACRO_DIRS], [])m4_defun([AC_CONFIG_MACRO_DIRS], [_AM_CONFIG_MACRO_DIRS($@)])]) m4_ifndef([AC_AUTOCONF_VERSION], [m4_copy([m4_PACKAGE_VERSION], [AC_AUTOCONF_VERSION])])dnl m4_if(m4_defn([AC_AUTOCONF_VERSION]), [2.69],, [m4_warning([this file was generated for autoconf 2.69.

Here's ## why we pick this rather obscure method: ## - Don't want to use -MD because we'd like the dependencies to end ## up in a subdir. Having to rename by hand is ugly. ## (We might end up doing this anyway to support other compilers.) ## - The DEPENDENCIES_OUTPUT environment variable makes gcc act like ## -MM, not -M (despite what the docs say).

We avoid this by adding ## dummy dependencies for each header file. Too bad gcc doesn't do ## this for us directly. ## Some versions of gcc put a space before the ':'. On the theory ## that the space means something, we add a space to the output as ## well. hp depmode also adds that space, but also prefixes the VPATH ## to the object.

You can embed shell variables for delayed # expansion at the time the message is displayed, but you will need to # quote other shell meta-characters carefully to prevent them being # expanded when the contents are evaled. usage='$progpath [OPTION]...' # Short help message in response to '-h' and '--help'.

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 iperf-3.9/docs/2017-06-06.txt000066400000000000000000000033311371560553300152320ustar00rootroot00000000000000Subject: 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). As mentioned in an earlier update, a lot of the issues we closed were user questions, not bug reports or enhancement requests. We'd like to direct user questions to either the mailing lists or to look on various question sites such as Stack Overflow. For bug reports (where you think iperf3 is doing something wrong) and enhancement requests (what can it do better), please file an issue. Thanks for your interest and support of iperf3, Bruce Mah Software Engineering Group ESnet iperf-3.9/docs/Makefile000066400000000000000000000151461371560553300151010ustar00rootroot00000000000000# Makefile for Sphinx documentation # # You can set these variables from the command line.

These pages are created using the Sphinx_ documentation package using the sphinx-bootstrap-theme_ with some pages. This repo is meant to be included into a project using git subtree and provides the overrides and customizations to the base theme. .. _Sphinx: http://sphinx-doc.org .. _sphinx-bootstrap-theme: https://github.com/ryan-roemer/sphinx-bootstrap-theme Installation ------------ 1. Install Sphinx and sphinx-bootstrap-theme. See the instructions below for installing these either using the Mac OS X base system python or MacPorts. 2. ``cd $PROJECT_ROOT`` 3. ``mkdir docs`` 4. ``git subtree add --prefix docs/_esnet https://github.com/esnet/esnet-gh-pages-base.git master --squash`` 5. ``cd docs`` 6. ``sphinx-quickstart`` 7. ``ln -s ../_esnet/static _static/esnet`` 8. edit ``conf.py`` as described in the next section Editing conf.py ^^^^^^^^^^^^^^^ ``sphinx-quickstart`` creates a basic conf.py file, however to use the ESnet theme we need to make some changes. Make the following changes to conf.py:: # add this with the imports at the top of the file import sphinx_bootstrap_theme # change templates_path to this templates_path = ['_esnet/templates'] # add _esnet to exclude_patterns exclude_patterns = ['_build', '_esnet'] # change html_theme and html_theme_path: html_theme = 'bootstrap' html_theme_path = sphinx_bootstrap_theme.get_html_theme_path() # add html_theme options: html_theme_options = { "navbar_pagenav": False, "nosidebar": False, "navbar_class": "navbar", "navbar_site_name": "Section", "source_link_position": "footer", "navbar_links": [ ("Index", "genindex"), ("ESnet", "https://www.es.net", True), ], } # add html_logo and html_sidebars html_logo = "_esnet/static/logo-esnet-ball-sm.png" html_sidebars = {'index': None, 'search': None, '*': ['localtoc.html']} html_favicon = "_esnet/static/favicon.ico" html_context = { "github_url": "https://github.com/esnet/PROJNAME", } That's it! Sphinx Installation using Mac OS X Base Python ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ 1. sudo /usr/bin/easy_install pip 2. sudo /usr/local/bin/pip install sphinx sphinx-bootstrap-theme Sphinx Installation using MacPorts ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ 1. port install python27 py27-pip py27-sphinx 2. port select pip py27-pip 3. port select sphinx py27-sphinx 4. pip install sphinx sphinx-bootstrap-theme # make sure this is /opt/local/bin/pip Creating Content, Previewing and Publishing ------------------------------------------- The files are in the ``docs`` directory. Take a look at the content of ``index.rst``. Take a look at the docs from other projects and review the documentation for Sphinx_. Building HTML ^^^^^^^^^^^^^ In the ``docs`` directory run ``make clean html``. Previewing the site ^^^^^^^^^^^^^^^^^^^ ``open _build/html/index.html`` or ``open -a /Application/Google\ Chrome.app _build/html/index.html`` Publishing the site ^^^^^^^^^^^^^^^^^^^ From the ``docs`` directory run ``_esnet/deploy.sh``. It will be visible at: ``http://github.com/esnet/PROJECT``. iperf-3.9/docs/_esnet/deploy.sh000077500000000000000000000006271371560553300165470ustar00rootroot00000000000000#!/bin/sh GIT_URL=`git remote show origin | awk '/Push URL/ { print $NF }'` DEPLOY_DIR=/tmp/deploy.$$ mkdir ${DEPLOY_DIR} (cd ${DEPLOY_DIR} ;

The instructions in this section assume that the source distribution has already been unpacked. Prerequisites ------------- iperf3 requires few (if any) dependencies on common operating systems. The only known prerequisites are listed here. Building -------- In many cases, iperf3 can be built and installed as follows: ``./configure && make && make install`` In some cases, configuration might fail. If this happens, it might help to run ``./bootstrap.sh`` first from the top-level directory. By default, the ``libiperf`` library is built in both shared and static forms. Either can be suppressed by using the ``--disabled-shared`` or ``--disable-static`` configure-time options. iperf-3.9/docs/conf.py000066400000000000000000000206451371560553300147400ustar00rootroot00000000000000# -*- coding: utf-8 -*- # # iperf documentation build configuration file, created by # sphinx-quickstart on Fri Mar 28 14:58:40 2014. # # This file is execfile()d with the current directory set to its # containing dir. # # Note that not all possible configuration values are present in this # autogenerated file. # # All configuration values have a default; values that are commented out # serve to show the default. import sys import os import sphinx_bootstrap_theme # If extensions (or modules to document with autodoc) are in another directory, # add these directories to sys.path here.

Mailing Lists ------------- The developer list for iperf3 is: iperf-dev@googlegroups.com. Information on joining the mailing list can be found at: http://groups.google.com/group/iperf-dev There is, at the moment, no mailing list for user questions, although a low volume of inquiries on the developer list is probably acceptable. If necessary, a user-oriented mailing list might be created in the future. Bug Reports ----------- Before submitting a bug report, try checking out the latest version of the code, and confirm that it's not already fixed. Also see the :doc:`faq`. Then submit to the iperf3 issue tracker on GitHub: https://github.com/esnet/iperf/issues **Note:** Issues submitted to the old iperf3 issue tracker on Google Code (or comments to existing issues on the Google Code issue tracker) will be ignored. Changes from iperf 2.x ---------------------- New options (not necessarily complete, please refer to the manual page for a complete list of iperf3 options):: -V, --verbose more detailed output than before -J, --json output in JSON format -Z, --zerocopy use a 'zero copy' sendfile() method of sending data -O, --omit N omit the first n seconds (to ignore slowstart) -T, --title str prefix every output line with this string -F, --file name xmit/recv the specified file -A, --affinity n/n,m set CPU affinity (Linux and FreeBSD only) -k, --blockcount #[KMG] number of blocks (packets) to transmit (instead of -t or -n) -L, --flowlabel set IPv6 flow label (Linux only) Changed flags:: -C, --linux-congestion set congestion control algorithm (Linux only) (-Z in iperf2) Deprecated flags (currently no plans to support):: -d, --dualtest Do a bidirectional test simultaneously -r, --tradeoff Do a bidirectional test individually -T, --ttl time-to-live, for multicast (default 1) -x, --reportexclude [CDMSV] exclude C(connection) D(data) M(multicast) S(settings) V(server) reports -y, --reportstyle C report as a Comma-Separated Values Also deprecated is the ability to set the options via environment variables. Known Issues ------------ The following problems are notable known issues, which are probably of interest to a large fraction of users or have high impact for some users, and for which issues have already been filed in the issue tracker. 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`` and ``RELEASE_NOTES`` files to be accurate. Make sure that the "Known Issues" section of the ``README`` 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 RELEASE_NOTES # 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 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. 13. If an update to the on-line manual page is needed, it can be generated with this sequence of commands (tested on CentOS 7) and import the result into ``invoking.rst``:: TERM= export TERM nroff -Tascii -c -man src/iperf3.1 | ul | sed 's/^/ /' > iperf3.txt Code Authors ------------ The main authors of iperf3 are (in alphabetical order): Jon Dugan, Seth Elliott, Bruce A. Mah, Jeff Poskanzer, Kaustubh Prabhu.

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 permanant (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. We don't want iperf3 to be an attack tool. I'm trying to use iperf3 to test a 40G/100G link...What do I need to know? See the following pages on fasterdata.es.net: - https://fasterdata.es.net/host-tuning/100g-tuning/ - https://fasterdata.es.net/performance-testing/network-troubleshooting-tools/iperf/multi-stream-iperf3/ My receiver didn't get all the bytes that got sent but there was no loss. 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. Actual bug reports, enhancement requests, or pull requests are encouraged, however. iperf-3.9/docs/index.rst000066400000000000000000000044551371560553300153030ustar00rootroot00000000000000.. iperf documentation master file, created by sphinx-quickstart on Fri Mar 28 14:58:40 2014. You can adapt this file completely to your liking, but it should at least contain the root `toctree` directive. iperf3 ====== The iperf series of tools perform active measurements to determine the maximum achievable bandwidth on IP networks. It supports tuning of various parameters related to timing, protocols, and buffers. For each test it reports the measured throughput, 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 incorporates 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 CentOS Linux, FreeBSD, and macOS. At this time, these are the only officially supported platforms, however there have been some reports of success with OpenBSD, Android, and other Linux distributions. iperf3 is principally developed by `ESnet `_ / `Lawrence Berkeley National Laboratory `_. It is released under a three-clause BSD license. iperf2 is no longer being developed by its original maintainers. However, beginning in 2014, another developer began fixing bugs and enhancing functionality, and generating releases of iperf2. Both projects (as of late 2017) are currently being developed actively, but independently. More information can be found in the :ref:`faq`.

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, iperf3 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``). iperf3 does also have flags for "extreme best case" optimizations but they must be explicitly activated. These flags include the ``-Z`` (``--zerocopy``) and ``-A`` (``--affinity``) options. iperf3 Manual Page ------------------ This section contains a plaintext rendering of the iperf3 manual page. It is presented here only for convenience; the text here might not correspond to the current version of iperf3. The authoritative iperf3 manual page is included in the source tree and installed along with the executable. :: IPERF3(1) User Manuals IPERF3(1) NAME iperf3 - perform network throughput tests SYNOPSIS iperf3 -s [ options ] iperf3 -c server [ options ] 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. 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 competely 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 -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 potentialy multiple CPUs). -B, --bind host bind to the specific interface associated with address host. If the host has multiple interfaces, it will use the first inter- face by default. -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. -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 -I, --pidfile file write a file with the process ID, most useful when running as a daemon. -1, --one-off handle one client connection, then exit. --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. CLIENT SPECIFIC OPTIONS -c, --client host 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. --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[KM] 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[KMG] 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[KM] 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[KM] number of bytes to transmit (instead of -t) -k, --blockcount n[KM] number of blocks (packets) to transmit (instead of -t or -n) -l, --length n[KM] 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 bidirectional mode, server and client send and receive data. -w, --window n[KM] window size / socket buffer size (this gets sent to the server and used on that side too) -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). -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 Omit the first n seconds of the test, 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. --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. --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. An example of a set of UNIX/Linux commands to generate correct keypair 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.

Beginning with the release of iperf 3.1, ESnet plans to support iperf3 in "maintenance mode". At this point, we have no definite plans for further iperf3 releases, and ESnet will be providing a very limited amount of resources for support and development, going forward. However, ESnet could issue new iperf3 releases to deal with security issues or high-impact bug fixes. Requests for support, enhancements, and questions should best be directed to the iperf-dev mailing list. ESnet would be open to adding project members/committers from the community, in case there are developers who are interested in doing more active work with iperf3 and/or supporting the user base. 2015-10-16: iperf-3.1 released ............................... | URL: http://downloads.es.net/pub/iperf/iperf-3.1.tar.gz | SHA256: ``4385a32ece25cb09d4606b4c99316356b3d2cb03b318aa056b99cdb91c5ce656 iperf-3.1.tar.gz`` This release adds support for SCTP on supported platforms, better feature detection on FreeBSD, better compatibility with various platforms, and a number of bug fixes. 2015-01-09: iperf-3.0.11 released .................................. | URL: http://downloads.es.net/pub/iperf/iperf-3.0.11.tar.gz | SHA256: ``e01db5be6f47f67c987463095fe4f5b8b9ff891fb92c39104d042ad8fde97f6e iperf-3.0.11.tar.gz`` This maintenance release adds a -1 flag to make the iperf3 execute a single test and exit, needed for an upcoming bwctl release.

Also, API calls have been added to libiperf to extend this functionality to API clients. * Some portability fixes for OpenBSD and Solaris have been merged from the mainline. As always, more details can be found in the ``RELEASE_NOTES`` file in the source distribution. 2014-06-16: Project documentation on GitHub Pages .................................................. iperf3 project documentation can now be found at: | URL: http://software.es.net/iperf/ This is a GitHub Pages site. In an ongoing series of steps, content will be migrated from the iperf3 wiki to GitHub Pages. 2014-06-16: iperf-3.0.5 released ................................. | URL: http://downloads.es.net/pub/iperf/iperf-3.0.5.tar.gz | SHA256: ``e1e1989985b17a4c03b0fa207004ad164b137e37ab0682fecbf5e93bcaa920a6 iperf-3.0.5.tar.gz`` This is the third maintenance release of iperf 3, with few more enhancements and bug fixes. Highlights: * A timing issue which caused measurement intervals to be wrong with TCP tests on lossy networks has been fixed. * It is now possible to get (most of) the server-side output at the client by using the ``--get-server-output`` flag. * A number of bugs with ``--json`` output have been fixed. A more extensive list of changes can always be found in the ``RELEASE_NOTES`` file in the source distribution. Note: An iperf-3.0.4 release was planned and tagged, but not officially released. 2014-06-10: New iperf3 download site ..................................... iperf3 downloads are now hosted on a new server at ESnet: | URL: http://downloads.es.net/pub/iperf/ Going forward, new releases will be made available in this directory. Older releases will, at least for now, continue to also be available at the previous location. 2014-03-26: iperf-3.0.3 released ................................. | URL: http://stats.es.net/software/iperf-3.0.3.tar.gz | SHA256: ``79daf3e5e5c933b2fc4843d6d21c98d741fe39b33ac05bd7a11c50d321a2f59d iperf-3.0.3.tar.gz`` This is the second maintenance release of iperf 3.0, containing a few bug fixes and enhancements, notably: * The structure of the JSON output is more consistent between the cases of one stream and multiple streams. * The example programs once again build correctly. * A possible buffer overflow related to error output has been fixed. (This is not believed to be exploitable.) More information on changes can be found in the ``RELEASE_NOTES`` file in the source distribution. 2014-03-10: iperf-3.0.2 released ................................. | URL: http://stats.es.net/software/iperf-3.0.2.tar.gz | SHA256: ``3c379360bf40e6ac91dfc508cb43fefafb4739c651d9a8d905a30ec99095b282 iperf-3.0.2.tar.gz`` **Note:** Due to a mistake in the release process, the distribution tarball referred to above is actually not compressed, despite its ``.tar.gz`` extension. Instead it is an uncompressed tar archive. The file checksum is correct, as are the file contents. This version is a maintenance release that fixes a number of bugs, many reported by users, adds a few minor enhancements, and tracks the migration of the iperf3 project to GitHub. Of particular interest: * Build / runtime fixes for CentOS 5, MacOS 10.9, and FreeBSD. * TCP snd_cwnd output on Linux in the default output format. * libiperf is now built as both a shared and static library; by default, the iperf3 binary links to the shared library. More information on changes can be found in the ``RELEASE_NOTES`` file in the source distribution. 2014-02-28: iperf migrated to GitHub ..................................... The new project page can be found at: https://github.com/esnet/iperf 2014-01-10: iperf-3.0.1 released ................................. | URL: http://stats.es.net/software/iperf-3.0.1.tar.gz | SHA256: ``32b419ef634dd7670328c3cecc158babf7d706bd4b3d248cf95965528a20e614 iperf-3.0.1.tar.gz`` During development, there were various distributions of the source code unofficially released carrying a 3.0.0 version number. Because of the possiblity for confusion, this first public release of iperf3 was numbered 3.0.1. iperf-3.9/docs/obtaining.rst000066400000000000000000000054141371560553300161420ustar00rootroot00000000000000.. _obtaining: Obtaining iperf3 ================ Binary Distributions -------------------- Note that ESnet does not distribute binary packages of iperf3. All of the packages listed in this section are provided by third parties, who are solely responsible for their contents. This is an incomplete list of binary packages: * FreeBSD: `benchmarks/iperf3 `_ in the FreeBSD Ports Collection * Fedora / CentOS: `iperf3 `_ and `iperf3-devel `_ in Fedora 19 and 20 and in Fedora EPEL 5, 6, and 7. iperf3 is included as a part of RedHat Enterprise Linux 7.4 and later (as well as CentOS 7.4 and later). * Ubuntu: `iperf3 `_, is available in Trusty (backports), and as a part of the main release in Vivid and newer. * macOS: via HomeBrew. * Windows: `iperf3 binaries for Windows `_ are available from iperf.fr (and other sources). Source Distributions -------------------- Source distributions of iperf are available as compressed (gzip) tarballs at: https://downloads.es.net/pub/iperf/ **Note:** Due to a software packaging error, the 3.0.2 release tarball was not compressed, even though its filename had a ``.tar.gz`` suffix. **Note:** GitHub, which currently hosts the iperf3 project, supports a "Releases" feature, which can automatically generate ``.zip`` or ``.tar.gz`` archives, on demand, from tags in the iperf3 source tree. These tags are created during the release engineering process to mark the exact version of files making up a release. In theory, the ``.tar.gz`` files produced by GitHub contain the same contents as what are in the official tarballs, note that the tarballs themselves will be different due to internal timestamps or other metadata. Therefore these files will *not* match the published SHA256 checksums and no guarantees can be made about the integrity of the files. The authors of iperf3 always recommend downloading source distributions from the the directory above (or a mirror site), and verifying the SHA256 checksums before using them for any purpose, to ensure the files have not been tampered with. Source Code Repository ---------------------- The iperf3 project is hosted on GitHub at: https://github.com/esnet/iperf The iperf3 source code repository can be checked out directly from GitHub using: ``git clone https://github.com/esnet/iperf.git`` Primary development for iperf3 takes place on CentOS 7 Linux, FreeBSD 11, and macOS 10.12. At this time, these are the only officially supported platforms, however there have been some reports of success with NetBSD, OpenBSD, Windows, Solaris, Android, and iOS. iperf-3.9/examples/000077500000000000000000000000001371560553300143205ustar00rootroot00000000000000iperf-3.9/examples/Makefile.am000066400000000000000000000004151371560553300163540ustar00rootroot00000000000000noinst_PROGRAMS = mic mis # Build, but don't install AM_CPPFLAGS = -I$(top_srcdir)/src mic_SOURCES = mic.c mic_CFLAGS = -g mic_LDADD = ../src/libiperf.la mic_LDFLAGS = -g mis_SOURCES = mis.c mis_CFLAGS = -g mis_LDADD = ../src/libiperf.la mis_LDFLAGS = -g iperf-3.9/examples/Makefile.in000066400000000000000000000527041371560553300163750ustar00rootroot00000000000000# Makefile.in generated by automake 1.16.2 from Makefile.am. # @configure_input@ # Copyright (C) 1994-2020 Free Software Foundation, Inc. # This Makefile.in is free software;

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 iperf3.example.com -p 5202 -R .PP Results are displayed on both the client and server. There will be at least one line of output per measurement interval (by default a measurement 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. .PP 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 \fC-R\fR flag will reverse these roles. .PP The client can be made to retrieve the server-side output for a given test by specifying the --get-server-output flag. .PP Either the client or the server can produce its output in a JSON structure, useful for integration with other programs, by passing it the -J flag. Because the contents of the JSON structure are only competely known after the test has finished, no JSON output will be emitted until the end of the test. .PP 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. .SH "GENERAL OPTIONS" .TP .BR -p ", " --port " \fIn\fR" set server port to listen on/connect to to \fIn\fR (default 5201) .TP .BR -f ", " --format " " [kmgtKMGT] format to report: Kbits/Mbits/Gbits/Tbits .TP .BR -i ", " --interval " \fIn\fR" pause \fIn\fR seconds between periodic throughput reports; default is 1, use 0 to disable .TP .BR -F ", " --file " \fIname\fR" 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. .TP .BR -A ", " --affinity " \fIn/n,m\fR" 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 \fIn\fR form of this argument (where \fIn\fR is a CPU number). In addition, on the client side you can override the server's affinity for just that one test, using the \fIn,m\fR 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 potentialy multiple CPUs). .TP .BR -B ", " --bind " \fIhost\fR" bind to the specific interface associated with address \fIhost\fR. .TP .BR -V ", " --verbose " " give more detailed output .TP .BR -J ", " --json " " output in JSON format .TP .BR --logfile " \fIfile\fR" send output to a log file. .TP .BR --forceflush " " force flushing output at every interval. Used to avoid buffering when sending output to pipe. .TP .BR --timestamps " [\fIformat\fR]" prepend a timestamp at the start of each output line. By default, timestamps have the format emitted by .BR ctime ( 1 ). Optionally, a format specification can be passed to customize the timestamps, see .BR strftime ( 3 ). .TP .BR -d ", " --debug " " emit debugging output. Primarily (perhaps exclusively) of use to developers. .TP .BR -v ", " --version " " show version information and quit .TP .BR -h ", " --help " " show a help synopsis .SH "SERVER SPECIFIC OPTIONS" .TP .BR -s ", " --server " " run in server mode .TP .BR -D ", " --daemon " " run the server in background as a daemon .TP .BR -I ", " --pidfile " \fIfile\fR" write a file with the process ID, most useful when running as a daemon. .TP .BR -1 ", " --one-off handle one client connection, then exit. .TP .BR --server-bitrate-limit " \fIn\fR[KMGT]" set a limit on the server side, which will cause a test to abort if the client specifies a test of more than \fIn\fR bits per second, or if the average data sent or received by the client (including all data streams) is greater than \fIn\fR 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. .TP .BR --rsa-private-key-path " \fIfile\fR" path to the RSA private key (not password-protected) used to decrypt authentication credentials from the client (if built with OpenSSL support). .TP .BR --authorized-users-path " \fIfile\fR" path to the configuration file containing authorized users credentials 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. .SH "CLIENT SPECIFIC OPTIONS" .TP .BR -c ", " --client " \fIhost\fR" 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. .TP .BR --sctp use SCTP rather than TCP (FreeBSD and Linux) .TP .BR -u ", " --udp use UDP rather than TCP .TP .BR --connect-timeout " \fIn\fR" set timeout for establishing the initial control connection to the server, in milliseconds. The default behavior is the operating system's timeout for TCP connection establishment. Providing a shorter value may speed up detection of a down iperf3 server. .TP .BR -b ", " --bitrate " \fIn\fR[KMGT]" set target bitrate to \fIn\fR 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. .TP .BR --pacing-timer " \fIn\fR[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. .TP .BR --fq-rate " \fIn\fR[KMGT]" Set a rate to be used with fair-queueing based socket-level pacing, in bits per second. This pacing (if specified) will be in addition to any pacing due to iperf3's internal throughput pacing (\-b/\--bitrate flag), and both can be specified for the same test. Only available on platforms supporting the \fCSO_MAX_PACING_RATE\fR socket option (currently only Linux). The default is no fair-queueing based pacing. .TP .BR --no-fq-socket-pacing This option is deprecated and will be removed. It is equivalent to specifying --fq-rate=0. .TP .BR -t ", " --time " \fIn\fR" time in seconds to transmit for (default 10 secs) .TP .BR -n ", " --bytes " \fIn\fR[KMGT]" number of bytes to transmit (instead of \-t) .TP .BR -k ", " --blockcount " \fIn\fR[KMGT]" number of blocks (packets) to transmit (instead of \-t or \-n) .TP .BR -l ", " --length " \fIn\fR[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. .TP .BR --cport " \fIport\fR" bind data streams to a specific client port (for TCP and UDP only, default is to use an ephemeral port) .TP .BR -P ", " --parallel " \fIn\fR" 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. .TP .BR -R ", " --reverse reverse the direction of a test, so that the server sends data to the client .TP .BR --bidir test in both directions (normal and reverse), with both the client and server sending and receiving data simultaneously .TP .BR -w ", " --window " \fIn\fR[KMGT]" window size / socket buffer size (this gets sent to the server and used on that side too) .TP .BR -M ", " --set-mss " \fIn\fR" set TCP/SCTP maximum segment size (MTU - 40 bytes) .TP .BR -N ", " --no-delay " " set TCP/SCTP no delay, disabling Nagle's Algorithm .TP .BR -4 ", " --version4 " " only use IPv4 .TP .BR -6 ", " --version6 " " only use IPv6 .TP .BR -S ", " --tos " \fIn\fR" 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. .TP .BR "--dscp " \fIdscp\fR 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). .TP .BR -L ", " --flowlabel " \fIn\fR" set the IPv6 flow label (currently only supported on Linux) .TP .BR -X ", " --xbind " \fIname\fR" Bind SCTP associations to a specific subset of links using sctp_bindx(3). The \fB--B\fR 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 association. Specifying at least one \fB--X\fR name will disable this behaviour. 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 \fB--X\fR argument to bind(2)). Hostnames are accepted as arguments and are resolved using getaddrinfo(3). If the \fB--4\fR or \fB--6\fR flags are specified, names which do not resolve to addresses within the specified protocol family will be ignored. .TP .BR --nstreams " \fIn\fR" Set number of SCTP streams. .TP .BR -Z ", " --zerocopy " " Use a "zero copy" method of sending data, such as sendfile(2), instead of the usual write(2). .TP .BR -O ", " --omit " \fIn\fR" Omit the first n seconds of the test, to skip past the TCP slow-start period. .TP .BR -T ", " --title " \fIstr\fR" Prefix every output line with this string. .TP .BR --extra-data " \fIstr\fR" Specify an extra data string field to be included in JSON output. .TP .BR -C ", " --congestion " \fIalgo\fR" Set the congestion control algorithm (Linux and FreeBSD only). An older .B --linux-congestion synonym for this flag is accepted but is deprecated. .TP .BR "--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 \fB--json\fR flag, the output will be in JSON format, otherwise it will be in human-readable format). If the client is run with \fB--json\fR, the server output is included in a JSON object; otherwise it is appended at the bottom of the human-readable output. .TP .BR --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. .TP .BR --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. .TP .BR --username " \fIusername\fR" username to use for authentication to the iperf server (if built with OpenSSL support). The password will be prompted for interactively 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. .TP .BR --rsa-public-key-path " \fIfile\fR" path to the RSA public key used to encrypt authentication credentials (if built with OpenSSL support) .SH EXAMPLES .SS "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. An example of a set of UNIX/Linux commands to generate correct keypair follows: .sp 1 .in +.5i > openssl genrsa -des3 -out private.pem 2048 .sp 0 > openssl rsa -in private.pem -outform PEM -pubout -out public.pem .sp 0 > openssl rsa -in private.pem -out private_not_protected.pem -outform PEM .in -.5i .sp 1 After these commands, the public key will be contained in the file public.pem and the private key will be contained in the file private_not_protected.pem. .SS "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 "{$user}$password". The file can also contain commented lines (starting with the \fC#\fR character). An example of commands to generate the password hash on a UNIX/Linux system is given below: .sp 1 .in +.5i > S_USER=mario S_PASSWD=rossi .sp 0 > echo -n "{$S_USER}$S_PASSWD" | sha256sum | awk '{ print $1 }' .in -.5i .sp 1 An example of a password file (with an entry corresponding to the above username and password) is given below: .sp 0 .in +.5i > cat credentials.csv .sp 0 # file format: username,sha256 .sp 0 mario,bf7a49a846d44b454a5d11e7acfaf13d138bbe0b7483aa3e050879700572709b .in -.5i .sp 1 .SH AUTHORS A list of the contributors to iperf3 can be found within the documentation located at \fChttps://software.es.net/iperf/dev.html#authors\fR. .SH "SEE ALSO" libiperf(3), https://software.es.net/iperf iperf-3.9/src/iperf_api.c000066400000000000000000004360331371560553300154040ustar00rootroot00000000000000/* * iperf, Copyright (c) 2014-2020, 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).

You can build it directly into your own program, instead of having to run it as a shell command. .SH CALLS Initialization / termination: .nf struct iperf_test *iperf_new_test(); int iperf_defaults(struct iperf_test *t); void iperf_free_test(struct iperf_test *t); .fi Setting test parameters: .nf void iperf_set_test_role( struct iperf_test *pt, char role ); void iperf_set_test_bind_address( struct iperf_test *t, char *bind_address ); void iperf_set_test_server_hostname( struct iperf_test *t, char *server_host ); void iperf_set_test_server_port( struct iperf_test *t, int server_port ); void iperf_set_test_duration( struct iperf_test *t, int duration ); void iperf_set_test_blksize( struct iperf_test *t, int blksize ); void iperf_set_test_num_streams( struct iperf_test *t, int num_streams ); void iperf_set_test_json_output( struct iperf_test *t, int json_output ); int iperf_has_zerocopy( void ); void iperf_set_test_zerocopy( struct iperf_test* t, int zerocopy ); void iperf_set_test_tos( struct iperf_test* t, int tos ); .fi Authentication functions: .nf void iperf_set_test_client_username(struct iperf_test *ipt, char *client_username) void iperf_set_test_client_password(struct iperf_test *ipt, char *client_password) void iperf_set_test_client_rsa_pubkey(struct iperf_test *ipt, char *client_rsa_pubkey_base64) .fi Running a test: .nf int iperf_run_client(struct iperf_test *); int iperf_run_server(struct iperf_test *); void iperf_reset_test(struct iperf_test *); .fi Output: .nf FILE *iperf_get_test_outfile(struct iperf_test *); char* iperf_get_test_json_output_string(struct iperf_test *); .fi Error reporting: .nf void iperf_err(struct iperf_test *t, const char *format, ...); char *iperf_strerror(int); extern int i_errno; .fi This is not a complete list of the available calls. See the include file for more. .SH EXAMPLES Here's some sample code that runs an iperf client: .nf struct iperf_test *test; test = iperf_new_test(); if ( test == NULL ) { fprintf( stderr, "%s: failed to create test\n", argv0 ); exit( EXIT_FAILURE ); } iperf_defaults( test ); iperf_set_test_role( test, 'c' ); iperf_set_test_server_hostname( test, host ); iperf_set_test_server_port( test, port ); if ( iperf_run_client( test ) < 0 ) { fprintf( stderr, "%s: error - %s\n", argv0, iperf_strerror( i_errno ) ); exit( EXIT_FAILURE ); } iperf_free_test( test ); .fi And here's a server: .nf struct iperf_test *test; test = iperf_new_test(); if ( test == NULL ) { fprintf( stderr, "%s: failed to create test\n", argv0 ); exit( EXIT_FAILURE ); } iperf_defaults( test ); iperf_set_test_role( test, 's' ); iperf_set_test_server_port( test, port ); for (;;) { if ( iperf_run_server( test ) < 0 ) fprintf( stderr, "%s: error - %s\n\n", argv0, iperf_strerror( i_errn o ) ); iperf_reset_test( test ); } iperf_free_test( test ); .fi These are not complete programs, just excerpts.

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). The elements are doubly linked * so that an arbitrary element can be removed without a need to * traverse the list. New elements can be added to the list before * or after an existing element or at the head of the list. A list * may only be traversed in the forward direction. * * A simple queue is headed by a pair of pointers, one the head of the * list and the other to the tail of the list. The elements are singly * linked to save space, so elements can only be removed from the * head of the list. New elements can be added to the list before or after * an existing element, at the head of the list, or at the end of the * list. A simple queue may only be traversed in the forward direction. * * A tail queue is headed by a pair of pointers, one to the head of the * list and the other to the tail of the list. The elements are doubly * linked so that an arbitrary element can be removed without a need to * traverse the list. New elements can be added to the list before or * after an existing element, at the head of the list, or at the end of * the list. A tail queue may be traversed in either direction. * * A circle queue is headed by a pair of pointers, one to the head of the * list and the other to the tail of the list. The elements are doubly * linked so that an arbitrary element can be removed without a need to * traverse the list. New elements can be added to the list before or after * an existing element, at the head of the list, or at the end of the list. * A circle queue may be traversed in either direction, but has a more * complex end of list detection. * * For details on the use of these macros, see the queue(3) manual page. */ #if defined(QUEUE_MACRO_DEBUG) || (defined(_KERNEL) && defined(DIAGNOSTIC)) #define _Q_INVALIDATE(a) (a) = ((void *)-1) #else #define _Q_INVALIDATE(a) #endif /* * Singly-linked List definitions. */ #define SLIST_HEAD(name, type) \ struct name { \ struct type *slh_first;
