# For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
# $ac_aux_dir to `$srcdir/foo'. In other projects, it is set to
# `$srcdir', `$srcdir/..', or `$srcdir/../..'.
#
# Of course, Automake must honor this variable whenever it calls a
# tool from the auxiliary directory. The problem is that $srcdir (and
# therefore $ac_aux_dir as well) can be either absolute or relative,
# depending on how configure is run. This is pretty annoying, since
# it makes $ac_aux_dir quite unusable in subdirectories: in the top
# source directory, any form will work fine, but in subdirectories a
# relative path needs to be adjusted first.
#
# $ac_aux_dir/missing
# fails when called from a subdirectory if $ac_aux_dir is relative
# $top_srcdir/$ac_aux_dir/missing
# fails if $ac_aux_dir is absolute,
# fails when called from a subdirectory in a VPATH build with
# a relative $ac_aux_dir
#
# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
# are both prefixed by $srcdir. In an in-source build this is usually
# harmless because $srcdir is `.', but things will broke when you
# start a VPATH build or use an absolute $srcdir.
#
# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
# iff we strip the leading $srcdir from $ac_aux_dir. That would be:
# am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
# and then we would define $MISSING as
# MISSING="\${SHELL} $am_aux_dir/missing"
# This will work as long as MISSING is not called from configure, because
# unfortunately $(top_srcdir) has no meaning in configure.
# However there are other variables, like CC, which are often used in
# configure, and could therefore not use this "fixed" $ac_aux_dir.
#
# Another solution, used here, is to always expand $ac_aux_dir to an
# absolute PATH. The drawback is that using absolute paths prevent a
# configured tree to be moved without reconfiguration.

## -MM, not -M (despite what the docs say).

## is deleted, the dependency causes make to die (because there is

## dummy dependencies for each header file. Too bad gcc doesn't do

Once you have the distribution, on UNIX,
unpack it using gzip and tar. That will create a new directory
'iperf-&lt;version#&gt;' with the source files and documentation.
<P>
Iperf compiles cleanly on many systems including Linux, SGI IRIX, HP-UX,
Solaris, AIX, and Cray UNICOS. Use '<TT>make</TT>' to configure for your OS and
compile the source code.
<BLOCKQUOTE><PRE>
gunzip -c iperf-&lt;version&gt;.tar.gz | tar -xvf -
cd iperf-&lt;version&gt;
./configure
make
</PRE></BLOCKQUOTE>
To install iperf, use '<TT>make install</TT>',
which will ask you where to install it. To recompile, the easiest way is to
start over. Do '<TT>make distclean</TT>' then '<TT>./configure; make</TT>'. See the Makefile
for more options.
<P>
If you have problems, please report them to <A href="mailto:dast@nlanr.net">dast@nlanr.net</A> and
we will try to fix them quickly. <BR>

<TD><A name=format></A><TT>-f, --format <I>[bkmaBKMA]</I></TT></TD>
<TD><TT>$IPERF_FORMAT</TT></TD>
<TD>A letter specifying the format to print bandwidth numbers in.
Supported formats are&nbsp;
<PRE>
&nbsp;&nbsp;&nbsp; 'b' = bits/sec&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 'B' = Bytes/sec
&nbsp;&nbsp;&nbsp; 'k' = Kbits/sec&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 'K' = KBytes/sec
&nbsp;&nbsp;&nbsp; 'm' = Mbits/sec&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 'M' = MBytes/sec
&nbsp;&nbsp;&nbsp; 'g' = Gbits/sec&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 'G' = GBytes/sec
&nbsp;&nbsp;&nbsp; 'a' = adaptive bits/sec&nbsp;&nbsp; 'A' = adaptive Bytes/sec
</PRE>
The adaptive formats choose between kilo- and mega- as appropriate. Fields
other than bandwidth always print bytes, but otherwise follow the
requested format. Default is 'a'.&nbsp; <BR><I>NOTE:</I> here Kilo = 1024,
Mega = 1024^2 and Giga = 1024^3 when dealing with bytes. Commonly in networking,
Kilo = 1000, Mega = 1000^2, and Giga = 1000^3 so we use this when dealing with
bits. If this really bothers you, use -f b and do the math.</TD></TR>
<TR vAlign=top>
<TD><A name=interval></A><TT>-i, --interval <I>#</I></TT></TD>
<TD><TT>$IPERF_INTERVAL</TT></TD>
<TD>Sets the interval time in seconds between periodic bandwidth, jitter,
and loss reports. If non-zero, a report is made every <I>interval</I>
seconds of the bandwidth since the last report. If zero, no periodic
reports are printed. Default is zero.</TD></TR>
<TR vAlign=top>
<TD><A name=len></A><TT>-l, --len <I>#[KM]</I></TT></TD>
<TD><TT>$IPERF_LEN</TT></TD>
<TD>The length of buffers to read or write. Iperf works by writing an
array of <I>len</I> bytes a number of times. Default is 8 KB for TCP, 1470
bytes for UDP. Note for UDP, this is the datagram size and needs to be lowered when using
IPv6 addressing to 1450 or less to avoid fragmentation. See also the <A
href="#num">-n</A>
and <A
href="#time">-t</A>
options.</TD></TR>
<TR vAlign=top>
<TD><A name=print_mss></A><TT>-m, --print_mss</TT></TD>
<TD><TT>$IPERF_PRINT_MSS</TT></TD>
<TD>Print the reported TCP MSS size (via the TCP_MAXSEG option) and the
observed read sizes which often correlate with the MSS. The MSS is usually
the MTU - 40 bytes for the TCP/IP header. Often a slightly smaller MSS is
reported because of extra header space from IP options. The interface type
corresponding to the MTU is also printed (ethernet, FDDI, etc.). This
option is not implemented on many OSes, but the read sizes may still
indicate the MSS.</TD></TR>
<TR vAlign=top>
<TD><A name=port></A><TT>-p, --port <I>#</I></TT></TD>
<TD><TT>$IPERF_PORT</TT></TD>
<TD>The server port for the server to listen on and the client to connect
to. This should be the same in both client and server. Default is 5001,
the same as ttcp.</TD></TR>
<TR vAlign=top>
<TD><A name=udp></A><TT>-u, --udp</TT></TD>
<TD><TT>$IPERF_UDP</TT></TD>
<TD>Use UDP rather than TCP. See also the <A
href="#bandwidth">-b</A>
option.</TD></TR>
<TR vAlign=top>
<TD><A name=window></A><TT>-w, --window <I>#[KM]</I></TT></TD>
<TD><TT>$TCP_WINDOW_SIZE</TT></TD>
<TD>Sets the socket buffer sizes to the specified value. For TCP, this
sets the TCP window size. For UDP it is just the buffer which datagrams
are received in, and so limits the largest receivable datagram size.</TD></TR>
<TR vAlign=top>
<TD><A name=bind></A><TT>-B, --bind <I>host</I></TT></TD>
<TD><TT>$IPERF_BIND</TT></TD>
<TD>Bind to <I>host</I>, one of this machine's addresses. For the client

<H2><A name=tuningtcp></A>Tuning a TCP connection</H2>
The primary goal of Iperf
is to help in tuning TCP connections over a particular path. The most
fundamental tuning issue for TCP is the TCP window size, which controls how much
data can be in the network at any one point. If it is too small, the sender will
be idle at times and get poor performance. The theoretical value to use for the
TCP window size is the <I>bandwidth delay product</I>,
<BLOCKQUOTE>bottleneck bandwidth * round trip time</BLOCKQUOTE>In the below
modi4/cyclops example, the bottleneck link is a 45 Mbit/sec DS3 link and the
round trip time measured with ping is 42 ms. The bandwidth delay product is
<BLOCKQUOTE>45 Mbit/sec * 42 ms <BR>= (45e6) * (42e-3) <BR>= 1890000 bits
<BR>= 230 KByte</BLOCKQUOTE>That is a starting point for figuring the best
window size; setting it higher or lower may produce better results. In our
example, buffer sizes over 130K did not improve the performance, despite the
bandwidth delay product of 230K.
<P>Note that many OSes and hosts have upper limits on the TCP window size. These
may be as low as 64 KB, or as high as several MB. Iperf tries to detect when
these occur and give a warning that the actual and requested window sizes are
not equal (as below, though that is due to rounding in IRIX). PSC has a <A
href="http://www.psc.edu/networking/perf_tune.html">list detailing</A> how to
change the default and maximum window sizes for various OSes. For more
information on TCP window sizes, see the <A
href="http://dast.nlanr.net/Guides/GettingStarted/TCP_window_size.html">User's
Guide to TCP Windows.</A>
<P>Here is an example session, between node1 in Illinois and node2 in North
Carolina. These are connected via the vBNS backbone and a 45 Mbit/sec DS3 link.
Notice we improve bandwidth performance by a factor of 3 using proper TCP window
sizes. Use the adaptive window sizes feature on platforms which allow setting
window sizes in the granularity of bytes.

test to do is run parallel TCP streams. If the total aggregate bandwidth is more
than what an individual stream gets, something is wrong. Either the TCP window
size is too small, or the OS's TCP implementation has bugs, or the network
itself has deficiencies. See above for TCP window sizes; otherwise diagnosing
which is somewhat difficult. If Iperf is compiled with pthreads, a single client
and server can test this, otherwise setup multiple clients and servers on
different ports. Here's an example where a single stream gets 16.5 Mbit/sec, but
two parallel streams together get 16.7 + 9.4 = 26.1 Mbit/sec, even when using
large TCP window sizes:

secondary tuning issue for TCP is the maximum transmission unit (MTU). To be
most effective, both hosts should support Path MTU Discovery. PSC has a <A
href="http://www.psc.edu/networking/perf_tune.html">list detailing</A> what OSes
support Path MTU Discovery. Hosts without Path MTU Discovery often use 536 as
the MSS, which wastes bandwidth and processing time. Use the -m option to
display what MSS is being used, and see if this matches what you expect. Often
it is around 1460 bytes for ethernet.

<H2><A name=tuningudp></A>Tuning a UDP connection</H2>
Iperf creates a constant bit rate UDP stream. This is a very artificial
stream, similar to voice communication but not much else.
<P>
You will want to adjust the datagram size (-l) to the size your application
uses.
<P>
The server detects UDP datagram loss by ID numbers in the datagrams. Usually
a UDP datagram becomes several IP packets. Losing a single IP packet will lose
the entire datagram. To measure packet loss instead of datagram loss, make the
datagrams small enough to fit into a single packet, using the -l option. The
default size of 1470 bytes works for ethernet. Out-of-order packets are also
detected. (Out-of-order packets cause some ambiguity in the lost packet count;
Iperf assumes they are not duplicate packets, so they are excluded from the lost
packet count.) Since TCP does not report loss to the user, I find UDP tests
helpful to see packet loss along a path.
<P>
Jitter calculations are continuously computed by the server, as specified by
RTP in RFC 1889. The client records a 64 bit second/microsecond timestamp in the
packet. The server computes the relative transit time as (server's receive time
- client's send time). The client's and server's clocks do not need to be
synchronized; any difference is subtracted out in the jitter calculation. Jitter
is the smoothed mean of differences between consecutive transit times.

<P>To test multicast, run several servers with the bind option (-B, --bind) set
to the multicast group address. Run the client, connecting to the multicast
group address and setting the TTL (-T, --ttl) as needed. Unlike normal TCP and
UDP tests, multicast servers may be started after the client. In that case,
datagrams sent before the server started show up as losses in the first periodic
report (61 datagrams on arno below).

<DD>Download the IPv6 version of this release.<BR>Get the IPv6 address of the node using the 'ifconfig' command.<BR>Use the <FONT color=#000099>-V</FONT> option to indicate that you are using an IPv6 address Please note that we need to explicitly bind the server address also.
<P>Server side:<BR><FONT color=#000099> $ iperf -s -V</FONT>
<P>Client side:<BR><FONT color=#000099>$ iperf -c &lt;Server IPv6 Address&gt; -V </FONT>

<P><A name=repmode></A>
<DL>
<DT><B><FONT size=+2>Using Representative Streams to measure

<DD>Use the -F or -I option. If you want to test how your network performs
with compressed / uncompressed streams, just create representative streams and
use the -F option to test it. This is usually due to the link layer
compressing data.
<P>The -F option is for file input.<BR>The -I option is for input from stdin.
<P>E.g. <BR>Client: $ <FONT color=#000099> iperf -c &lt;server address&gt; -F &lt;file-name&gt;<BR></FONT>
<BR>Client: $ <FONT color=#000099> iperf -c &lt;server address&gt; -I </FONT></P></DD></DL>
<P><A name=daemon></A>
<HR>
<DL>
<DT><B><FONT size=+2>Running the server as a daemon</FONT></B>
<DD>Use the -D command line option to run the server as a daemon. Redirect the
output to a file.<BR>E.g. <FONT color=#000099>iperf -s -D &gt;
iperfLog</FONT>. <FONT color=#000000>This will have the Iperf Server running
as a daemon and the server messages will be logged in the file iperfLog.
</DD></DL>
<HR>
<P><A name=service></A>
<DL>
<DT><B><FONT size=+2>Using Iperf as a Service under Win32</FONT></B>
<DD>There are three options for Win32:
<P>
<DL>
<DT>-o outputfilename
<DD>output the messages into the specified file
<DT>-s -D
<DD>install Iperf as a service and run it
<DT>-s -R
<DD>uninstall the Iperf service </DD></DL>
<P>Examples:
<DL>
<DT><FONT color=#3366ff>iperf -s -D -o iperflog.txt</FONT>
<DD>will install the Iperf service and run it. Messages will be reported
into "%windir%\system32\iperflog.txt"
<P></P>
<DT><FONT color=#3366ff>iperf -s -R</FONT>
<DD>will uninstall the Iperf service if it is installed.
<P>Note: If you stop want to restart the Iperf service after having killed
it with the Microsoft Management Console or the Windows Task Manager, make
sure to use the proper OPTION in the service properties dialog.
</P></DD></DL></DD></DL>
<HR>
<!--<P><A name=multicast></A>
<DL>
<DT><B><FONT size=+2>Running the multicast server and client</FONT></B>
<DD>Use the -B option while starting the server to bind it to a multicast
address.<BR>E.g. :-<FONT color=#3366ff>iperf -s -u -B 224.0.55.55</FONT>.
<P>This will have the Iperf server listening for datagrams (-u) for the
address 224.0.55.55(-B 224.0.55.55).
<P>Now, start a client sending packets to this multicast address.
<P>E.g. : <FONT color=#3366ff>iperf -c 224.0.55.55 -u</FONT>.
This will have a UDP client (-u) sending to the multicast address
224.0.55.55(-c 224.0.55.55).
<P><FONT color=#000000>Start multiple clients or servers as explained above,
sending data to the same multicast server. (If you have multiple servers
listening on the multicast address, each of the servers will be getting the data)
</P></DD></DL>
<HR>-->
<!--<A name=adaptive></A>
<DL>
<DT><B><FONT size=+2>Adaptive window sizes</FONT></B>
<DD>Use the -W option on the client to run the client with the adaptive window
size. Ensure that the server window size is fairly big for this
option.<BR>E.g.. If the server TCP window size is 8KB, it does not help having
a client TCP window size of 256KB.<BR>256KB Server TCP Window Size should
suffice for most high bandwidth networks.
<P>Client changes the TCP window size using a binary exponential
algorithm. This means that you may notice that TCP window size suggested may
vary according to the traffic in the network, Iperf will suggest the best
window size for the current network scenario.

* Extract data from a file, used to measure the transfer rates
* for various stream formats.
*
* E.g. Use a gzipped file to measure the transfer rates for
* compressed data
* Use an MPEG file to measure the transfer rates of
* Multimedia data formats
* Use a plain BMP file to measure the transfer rates of
* Uncompressed data
*
* This is beneficial especially in measuring bandwidth across WAN
* links where data compression takes place before data transmission

The LONG_OPTIONS argument to gnu_getopt_long or getopt_long_only is a vector

no_argument (or 0) if the option does not take an argument,
required_argument (or 1) if the option requires an argument,
optional_argument (or 2) if the option takes an optional argument.
If the field `flag' is not NULL, it points to a variable that is set
to the value given in the field `val' when the option is found, but
left unchanged if the option is not found.
To have a long-named option do something other than set an `int' to
a compiled-in constant, such as set a value from `gnu_optarg', set the
option's `flag' field to zero and its `val' field to a nonzero
value (the equivalent single-letter option character, if there is
one). For long options that have a zero `flag' field, `gnu_getopt'

// MODULE: service.h
//
// AUTHOR: Craig Link
//
//
// Comments: The use of this header file and the accompanying service.c
// file simplifies the process of writting a service. You as a developer
// simply need to follow the TODO's outlined in this header file, and
// implement the ServiceStart() and ServiceStop() functions.
//
// There is no need to modify the code in service.c. Just add service.c
// to your project and link with the following libraries...
//
// libcmt.lib kernel32.lib advapi.lib shell32.lib
//
// This code also supports unicode. Be sure to compile both service.c and
// and code #include "service.h" with the same Unicode setting.
//
// Upon completion, your code will have the following command line interface
//
// <service exe> -? to display this list
// <service exe> -install to install the service
// <service exe> -remove to remove the service
// <service exe> -debug <params> to run as a console app for debugging
//
// Note: This code also implements Ctrl+C and Ctrl+Break handlers
// when using the debug option. These console events cause
// your ServiceStop routine to be called
//
// Also, this code only handles the OWN_SERVICE service type
// running in the LOCAL_SYSTEM security context.
//
// To control your service ( start, stop, etc ) you may use the
// Services control panel applet or the NET.EXE program.
//
// To aid in writing/debugging service, the
// SDK contains a utility (MSTOOLS\BIN\SC.EXE) that
// can be used to control, configure, or obtain service status.
// SC displays complete status for any service/driver
// in the service database, and allows any of the configuration
// parameters to be easily changed at the command line.
// For more information on SC.EXE, type SC at the command line.

Unix `getopt' but it behaves differently for the user, since it
allows the user to intersperse the options with the other
arguments.
As `gnu_getopt' works, it permutes the elements of ARGV so that,
when it is done, all the options precede everything else. Thus
all application programs are extended to handle flexible argument order.
Setting the environment variable POSIXLY_CORRECT disables permutation.
Then the behavior is completely standard.
GNU application programs can use a third alternative mode in which

/* Describe how to deal with options that follow non-option ARGV-elements.
If the caller did not specify anything,
the default is REQUIRE_ORDER if the environment variable
POSIXLY_CORRECT is defined, PERMUTE otherwise.
REQUIRE_ORDER means don't recognize them as options;
stop option processing when the first non-option is seen.
This is what Unix does.
This mode of operation is selected by either setting the environment
variable POSIXLY_CORRECT, or using `+' as the first character
of the list of option characters.
PERMUTE is the default. We permute the contents of ARGV as we scan,
so that eventually all the non-options are at the end. This allows options
to be given in any order, even with programs that were not written to
expect this.
RETURN_IN_ORDER is an option available to programs that were written
to expect options and other ARGV-elements in any order and that care about
the ordering of the two. We describe each non-option ARGV-element
as if it were the argument of an option with character code 1.
Using `-' as the first character of the list of option characters
selects this mode of operation.
The special argument `--' forces an end of option-scanning regardless
of the value of `ordering'. In the case of RETURN_IN_ORDER, only
`--' can cause `gnu_getopt' to return -1 with `gnu_optind' != ARGC. */

/* Scan elements of ARGV (whose length is ARGC) for option characters
given in OPTSTRING.
If an element of ARGV starts with '-', and is not exactly "-" or "--",
then it is an option element. The characters of this element
(aside from the initial '-') are option characters. If `gnu_getopt'
is called repeatedly, it returns successively each of the option characters
from each of the option elements.
If `gnu_getopt' finds another option character, it returns that character,
updating `gnu_optind' and `nextchar' so that the next call to `gnu_getopt' can
resume the scan with the following option character or ARGV-element.
If there are no more option characters, `gnu_getopt' returns -1.
Then `gnu_optind' is the index in ARGV of the first ARGV-element
that is not an option. (The ARGV-elements have been permuted
so that those that are not options now come last.)
OPTSTRING is a string containing the legitimate option characters.
If an option character is seen that is not listed in OPTSTRING,
return '?' after printing an error message. If you set `gnu_opterr' to
zero, the error message is suppressed but we still return '?'.
If a char in OPTSTRING is followed by a colon, that means it wants an arg,
so the following text in the same ARGV-element, or the text of the following
ARGV-element, is returned in `gnu_optarg'. Two colons mean an option that
wants an optional arg; if there is text in the current ARGV-element,
it is returned in `gnu_optarg', otherwise `gnu_optarg' is set to zero.
If OPTSTRING starts with `-' or `+', it requests different methods of
handling the non-option ARGV-elements.
See the comments about RETURN_IN_ORDER and REQUIRE_ORDER, above.
Long-named options begin with `--' instead of `-'.
Their names may be abbreviated as long as the abbreviation is unique
or is an exact match for some defined option. If they have an
argument, it follows the option name in the same ARGV-element, separated
from the option name by a `=', or else the in next ARGV-element.
When `gnu_getopt' finds a long-named option, it returns 0 if that option's
`flag' field is nonzero, the value of the option's `val' field
if the `flag' field is zero.
The elements of ARGV aren't really const, because we permute them.
But we pretend they're const in the prototype to be compatible
with other systems.
LONGOPTS is a vector of `struct option' terminated by an
element containing a name which is zero.
LONGIND returns the index in LONGOPT of the long-named option found.
It is only valid when a long-named option has been found by the most
recent call.
If LONG_ONLY is nonzero, '-' as well as '--' can introduce
long-named options. */
