I2Addr usage - single host test configuration (documentation as well) Better peer connection problem detection More simple user/passwd config file setup - notice key changes without restart? tool specific output flags csv output from iperf nmwg output? separate common pieces from man-pages similar to owamp ----- And one other minor request: Could it try iperf first, before nuttcp, so we dont see this nuttcp warnings every time? That is from the client spawning off the server... It is trying all the tools to see what is available to it, then the client contacts it to find out what the server supports. (This is what I mean by a more complicated mode...) There may be a way to disable nuttcp using the .bwctlrc file... Or there may at least be an easy way to add that there. ----- bwctl-1.4.1/conf/0000775000076700007720000000000012040244644010572 500000000000000bwctl-1.4.1/conf/bwctld.conf0000664000076700007720000001436012015235427012645 00000000000000# # $Id: bwctld.conf 514 2009-01-14 13:53:46Z aaron $ # ######################################################################### # # # Copyright (C) 2003 # # Internet2 # # All Rights Reserved # # # ######################################################################### # # File: bwctld.conf # # Author: Jeff W.

NAME

bwctld.keys - Bandwidth Control Daemon AES keyfile database  

DESCRIPTION

The bwctld.keys file is used to hold the identity/AES keys pairs needed for bwctld to authenticate users. The format of this file is described in the aespasswd(1) manual page. The location of this file is controlled by the -c option to bwctld but it must be named bwctld.keys.

bwctld uses symmetric AES keys for authentication. Therefore, the bwctl client will have to have access to the exact same AES key for authentication by AES to work. Most likely, the user will simply know the passphrase that generated the AES key in the first place. Additionally, it is important that the system administrator and end user ensure the key is not compromised.

If the bwctl client is able to authenticate using the identity and AES key presented, bwctld will use the directives found in the bwctld.limits file to map policy restrictions to this connection.  

SECURITY CONSIDERATIONS

The keys in the bwctld.keys file are not encrypted in any way. The security of these keys is completely dependent upon the security of the system and the discretion of the system administrator.  

RESTRICTIONS

Identity names are restricted to 16 characters.

BWCTL is a command line client application and a scheduling and policy daemon that wraps the throughput testing tools Iperf, Thrulay, and Nuttcp. These tests can measure maximum TCP bandwidth, with various tuning options available, or, by doing a UDP test, the delay, jitter, and datagram loss of a network.

The bwctl client application works by contacting a bwctld process on the two test endpoint systems. BWCTL will work as a 3-party application. The client can arrange a test between two servers on two different systems. If the local system is intended to be one of the endpoints of the test, bwctl will detect whether a local bwctld is running and will handle the required server functionality if needed. bwctld manages and schedules the resources of the host on which it runs. A more detailed description of the architecture is available in the architecture documentation.

The bwctl client is used to request the type of throughput test wanted. Furthermore, it requests when the test should be executed. bwctld either responds with a tentative reservation or a test denied message. Once bwctl is able to get a matching reservation from both bwctld processes (one for each host involved in the test), it confirms the reservation. Then, the bwctld processes run the test and return the results. The results are returned to the client from both sides of the test. Additionally, the bwctld processes share the results from their respective sides of the test with each other.

BWCTL is used to enable non-specific throughput tests to a host without having to give full user accounts on the given system. Users want the ability to run throughput tests to determine the achievable or available bandwidth between a pair of hosts. It is often useful to test to multiple points along a network path to determine the network characteristics along that path. Typically, users who want to do this path decomposition have to contact the network/system administrators that control the hosts along the path directly. The administrator needs to either run half of the test for the user or provide a user account on the host. Also, network paths of interest usually are controlled by multiple administrators. These hurdles have made this kind of testing difficult in practice.

BWCTL was designed to help with this problem. It allows an administrator to configure a given host as an Iperf, Thrulay or Nuttcp endpoint that can be shared by multiple users without concern that those users will interfere with each other. Specific policy limits can be applied to specific users, and individual tests are scheduled so they will not interfere with each other. BWCTL allows the administrator to classify incoming connections based upon a user name and AES key (generated by a pass phrase) combination or, alternatively, based upon an IP/netmask. Once the connection is classified, the bwctld can determine the exact type and intensities of throughput tests that will be allowed. (More details on the policy controls can be found in the bwctld.limits(8) manual page.)

Features

Requirements

Supported Systems

BWCTL has been tested most extensively on Red Hat Linux 4 and 5 systems, but most recent versions of UNIX should work. The code cleanly compiles on FreeBSD, Linux, and OS X.

BWCTL compiles on Solaris. However, Thrulay does not work on that platform so is not compiled in. If anyone has any interest in updating thrulay to work on Solaris, let us know.

Recommended Hardware

BWCTL does not have any strict hardware requirements. The limits imposed by the specific throughput tests are more taxing to hardware than the scheduling and policy functions added by BWCTL. The hardware requirements are therefore a function of the specific throughput tests that are desired. Internet2 had good luck using the following hardware to perform 1Gbps tests on the Abilene network:
Intel SCB2 motherboard
2 x 1.266 GHz PIII, 512 KB L2 cache, 133 MHz FSB
2 x 512 MB ECC registered RAM (one/slot to enable interleaving)
2 x Seagate 18 GB SCSI (ST318406LC)
SysConnect Gigabit Ethernet SK-9843 SX

Building the Application

The BWCTL software uses the gnu autoconf tools to configure the build process. BWCTL is distributed with a pre-built configure script so the actual autoconf tools should not be needed on the target system. (Although, gnumake may be required.) The configure script can be run with the --help option to determine the full set of configurable options.

A basic build procedure would be: 

% gzip -cd bwctl-$VERS.tar.gz | tar xf -
% cd bwctl-$VERS
  # --prefix is only needed if you don't like the default
  #   (/usr/local on most systems)
% ./configure --prefix=/install/root
% make
% make install
Please report any build problems to bwctl-users@internet2.edu.

Configuring bwctld

The basic procedure to configure bwctld is to create a bwctld.conf and, optionally, a bwctld.limits file and a bwctld.keys file. These files need to be installed in the same directory that is specified with the -c option to bwctld. The recommended directory is /install/root/etc. (The etc directory below your install root.) There are examples of these files in the bwctl-$VERS/conf  sub directory of the distribution.

bwctld.conf:
Used to configure basic operation of the daemon, such as server listening port, the path for Iperf, and error logging. For a detailed description of the options available, see the bwctld.conf(8) manual page.

bwctld.limits:
Used to configure the policy limits for the daemon. There are two parts to this policy: 1) authentication and 2) authorization. The authentication is done by assigning a class to each new connection. Each class has a set of limits associated with it. The classes are hierarchical, so a connection must pass the limit restrictions of the assigned class as well as all parent classes. For a detailed description of the options available, see the bwctld.limits(8) manual page.

bwctl.keys:
Used to associate identities with AES keys. These identities are then mapped to a class by the bwctld.limits file. For a more detailed description, see the bwctld.keys(8) manual page.

Configuring firewalls

If a firewall is enabled on the machine running bwctld, it will need to be configured to allow incoming clients and tests. Use this set of directions to configure the firewall.

Configuring NTP

To ensure that tests can be run, the machine running bwctld should have its clock synchronized using NTP. Use this set of directions to configure NTP.

Running bwctld

The normal command line to start the daemon is: 
 % bwctld -c /install/root/etc
It is possible to run the daemon without a config file directory if enough command line options are specified, but it is easier to use a config file.

To see all the available options: 

 % bwctld -h
More details on running the daemon, as well as a complete description of the command line options, is available from the bwctld manual page.

Running bwctl

The basic command line for the client is: 
% bwctl [options] [-c catchhost] [-s sendhost]
The -c option indicates that the catchhost should be an Iperf server (think packet catcher). The -s option indicates the sendhost should be an Iperf client (think packet sender). At least one of the -c/-s options must be specified. If only one of these options is specified, the local host is assumed to be the other test endpoint.

To see a list of available options: 

% bwctl -h
More details on running the client application, with a complete description of all command line options, is available from the bwctl manual page.

Caveats

Thrulay support is deprecated. If there is enough desire, or if someone is willing to maintain thrulay, the functionality could be undeprecated.
Mailing Lists There are two email lists to support this software:
bwctl-users
This is a general discussion list for users to discuss problems. This list is monitored as bug reports should be sent here.
bwctl-announce
This list is used to announce new versions or significant developments with regard to the software.
Information about these lists, including links to subscribe, is at https://mail.internet2.edu/wws/lists/engineering.

This option is used to bypass this requirement for systems that either do not have the NTP system calls, or prefer not to configure NTP. .RS .PP Note: if the difference between the system clocks on the two endpoints is too great, the eventual throughput test will fail when the endpoints attempt to run the test at different times.

These connections are used to verify clock timing between the servers and to exchange test results. This is a required part of the protocol used by .B BWCTL to run tests. However, this option allows system administrators to limit these connections to a specific port range, which should allow .B BWCTL to work in a firewall environment. This option can be specified in two ways. First, as a 0, which would indicate that .B bwctld should allow the system to pick the port (ephemeral). Second, as a range. .I lowport must be a smaller value than .I highport and both numbers must be valid port values. (16-bit unsigned integer values) .RS .IP Default: 0 .RE .TP .BI post_hook " /path/to/script" Specifies a script to run after each bwctl session has finished. These hooks can be used to save the results into a database, track usage or any number of other tasks.

There are legitimate reasons to run \fBbwctld\fR as root, but it is risky. Forcing this additional option will make it less likely root permissions are accidently used. .RS .IP Default: unset .RE .TP .BI src_node " nodename:port" Specify the address and port on which \fBbwctld\fR will listen for requests. \fInodename\fR can be specified using a DNS name or using the textual representation of the address. It is possible to set the source address without setting the \fIport\fR by simply leaving off the ':' and \fIport\fR specification. If an IPv6 address is specified, note that the accepted format contains \fInodename\fR in square brackets as: [fe80::fe9f:62d8]. This ensures the port number is distinct from the address specification. .RS .IP Default: \fInodename\fR is wildcarded as any currently available address .br \fIport\fR is 4823 .RE .TP .BI sync_fuzz " syncfuzz" This value is added to the NTP error estimates to increase the tolerance of \fBbwctld\fR to incomplete NTP configurations, or if the NTP system calls are not available. If NTP is unavailable to \fBbwctld\fR it assumes the clock is accurate to within one second plus the value of \fIsync_fuzz\fR. This option is specified as a floating point number in seconds. For example, to indicate that the system is synchronized within one second, you could specify this option as 1.0. .RS .PP Practically, this option is used to determine the size of the time window buffer before and after each throughput test. .IP Default: 0.0 .RE .TP .BI thrulay_port " thrulayport" The port number(s) that \fBThrulay\fR receivers will use.

Time Synchronization

BWCTL works best when the clocks of the clients and servers are synchronized. If the hosts are not synchronized, they might try to begin tests at different times.

NTP is a protocol used to synchronize a computer's clock to clocks available over a network. The NTP software is available for, and often times, included with many operating systems. Most Unix systems use the reference implementation of the software, and the example included with this howto is geared to that version.

ntp.org has some advice for selecting NTP servers. However, there are some general rules of thumb to follow for NTP configuration. The NTP configuration should include between 4 and 7 NTP clocks with which it will try to synchronize. By including this number of servers, the NTP software can make better decisions about which clocks are accurate and who it should trust for time data. The NTP servers should be in close proximity to the host, though this is not a hard requirement. Ideally, the network paths to the servers should differ as much as possible from each other.

There are a large number of public NTP servers. There's a list available at http://support.ntp.org/bin/view/Servers/WebHome.

Internet2 maintains a set of NTP servers that can be used if the host is connected to the Internet2 network.

NAME

bwctl - Client application to request throughput tests.  

SYNOPSIS

bwctl [options] -c recvhost -s sendhost
bwctl [options] -c recvhost
bwctl [options] -s sendhost  

DESCRIPTION

bwctl is a command line client application that is used to initiate throughput tests.
This version of bwctl is capable of initiating Iperf, Nuttcp, and Thrulay tests.

bwctl works by contacting a bwctld daemon on both the receiving host and the sending host. bwctld manages and schedules the resources of the host it runs on. In the case where only one of the receiving host or sending host is specified, bwctl assumes the local host is the other endpoint. bwctl will attempt to contact a local bwctld if it can. If there is no local bwctld running, bwctl assumes the local host does not require policy controls and will execute the bwctld functionality required to run the test directly.

If cases where bwctl is directly running the throughput test on the host, there are several configuration options that are shared with bwctld. Those configuration options can be set using the bwctlrc(5) configuration file in a way very similar to the way they are specified in the bwctld.conf(5) file.

The bwctl client is used to request the desired type of throughput test. Furthermore, it requests when the test is wanted. bwctld on each endpoint either responds with a tentative reservation or a test denied message. Once bwctl is able to get a matching reservation from both bwctld processes (one for each host involved in the test), it confirms the reservation. Then, the bwctld processes run the test and return the results. The results are returned to the client from both sides of the test from the respective bwctld processes. Additionally, the bwctld processes share the results from their respective side of the test with each other.

BWCTL (bwctl and bwctld) is used to enable non-specific throughput tests to hosts without having to give full user accounts on the given systems. Users want the ability to run throughput tests to determine the achievable or available bandwidth between a pair of hosts. It is often useful to test to multiple points along a network path to determine the network characteristics along that path. Typically, users who want to do this path decomposition have to directly contact the network/system administrators who control the hosts along the path. The administrator needs to either run half of the test for the user or give them a user account on the host. Also, network paths of interest are typically controlled by multiple administrators. These hurdles have made this kind of testing difficult in practice.

BWCTL was designed to help with this problem. It allows an administrator to configure a given host as an Iperf, Thrulay, or Nuttcp endpoint. The endpoint can be a packet sender (e.g. Iperf client) or a packet receiver (e.g. Iperf server). It can be shared by multiple users without concern that those users will interfere with each other. Specific policy limits can be applied to specific users, and individual tests are scheduled so they will not interfere with each other. Additionally, full user accounts are not required for the users running the tests.

BWCTL allows the administrator to classify incoming connections based upon a user name and AES key combination or, alternatively, based upon an IP/netmask. Once the connection is classified, the bwctld can determine the exact type and intensities of througput tests that will be allowed. More information on the policy controls can be found in the bwctld(8) man page.

BWCTL makes use of a distributed scheduling algorithm. Each host maintains a schedule independently. As a client requests a test, the two endpoints are contacted and each bwctld server responds with the first available open schedule slot. This enables on-demand tests to co-exist with regularly scheduled tests since regularly scheduled tests are implemented by having the client request tests on regular intervals. Different priorities can be implemented using the event_horizon configuration directive to bwctld. (By allowing clients that implement regularly scheduled tests to reserve their time slots further into the future.)  

ARGUMENTS

 

Connection/Authentication Arguments:

-4
Forces bwctl to use IPv4 addresses only.
Default:
Unspecified (IPv6 is preferred).
-6
Forces bwctl to use IPv6 addresses only.
Default:
Unspecified (IPv6 is preferred).
-A authmethod
authmethod is used to specify the authentication method the bwctl client is willing to use for communication with the bwctld on the sendhost and recvhost. The authentication options of bwctl are intended to be extensible. The communication from the bwctl client to each bwctld server may take different options for different types of authentication. If the authmethod option is specified for either the -s, or the -c argument, it overrides the authmethod specified with the -A option for communication with that particular host. (Therefore, the -A argument is really only useful if the same authentication can be used with both hosts.)

Allowing different authentication methods for each connection should allow a client to use different authentication methods with different servers which should in turn allow cross-domain tests to occur more easily.

The format for authmethod is:

authmode [authscheme schemeopts]

authmode
Specifies the authentication mode the client is willing to speak with a server. It must be set as a character string with any or all of the characters "AEO". The modes are:
A
[A]uthenticated. This mode encrypts the control connection.
E
[E]ncrypted. This mode encrypts the control connection. If the test supports encryption, this mode will additionally encrypt the test stream. (Encryption of the test stream is not currently supported, so this mode is currently identical to authenticated.)
O
[O]pen. No encryption of any kind is done.

The client can specify all the modes with which it is willing to communicate. The most strict mode that both the server and the client are willing to use will be selected.

Default:
"AEO"
authscheme schemeopts
authscheme indicates the authentication scheme that should be used to achieve the authenticated or encrypted modes. schemeopts are a list of arguments specific to each particular authentication scheme. Supported authscheme values follow (listed with the schemeopts each scheme requires):
AESKEY userid [keyfile]
This is the initial "simple" shared secret (AES key) model. userid is required to identify which shared secret the server and client should use. keyfile optionally specifies a file to retrieve the AES key from. If keyfile is not specified, the user will be prompted for a passphrase. keyfile can be generated using the aespasswd(1) application.
Default:
Unauthenticated

authscheme and schemeopts are only needed if authenticated communication (A or E modes of authmode) is wanted with sendhost and recvhost.

-B srcaddr
Bind the local address of the client socket to srcaddr. srcaddr can be specified using a DNS name or using standard textual notations for the IP addresses.
Default:
Unspecified (wild-card address selection).
-c recvhost[:port] [authmethod]
Specifies the host that will run the Iperf, Thrulay or Nuttcp server. The :port suffix is optional and is only needed if bwctld is being run on a non-default port number. If an IPv6 address is being specified, note that the accepted format contains the recvhost portion of the specification in square brackets as: [fe80::fe9f:62d8]:4823. This ensures the port number is distinct from the address specification, and is not needed if the :port suffix is not being used.

At least one of the -c or -s options must be specified. If one of them is not specified, it is assumed to be the local host.

authmethod is a specifically ordered list of keywords that is only needed if authenticated communication is wanted with recvhost. These keywords are used to describe the type of communication and authentication that should be used to contact the recvhost. If recvhost and sendhost share the same authentication methods and identities, it is possible to specify the authmethod for both recvhost and sendhost using the -A argument. An authmethod specified with the -c option will override an authmethod specified with the -A argument for communication with the recvhost.

The format for authmethod and a description of the currently available authentication methods are described with the -A argument.

-k

This option has been deprecated. Originally, it was used to specify the keyfile for authentication. All authentication options can now be specified using the -A argument. For the next several versions this option will report an error. Eventually, it may be reclaimed for another purpose.
-s sendhost[:port] [authmethod]
Specifies the host that will run the Iperf, Thrulay or Nuttcp client. The :port suffix is optional and is only needed if bwctld is being run on a non-default port number. If an IPv6 address is being specified, note that the accepted format contains the sendhost portion of the specification in square brackets as: [fe80::fe9f:62d8]:4823. This ensures the port number is distinct from the address specification, and is not needed if the :port suffix is not being used.

At least one of the -c or -s options must be specified. If one of them is not specified, it is assumed to be the local.

authmethod is a specifically ordered list of keywords that is only needed if authenticated communication is wanted with sendhost. These keywords are used to describe the type of communication and authentication that should be used to contact the sendhost. If recvhost and sendhost share the same authentication methods and identities, it is possible to specify the authmethod for both recvhost and sendhost using the -A argument. An authmethod specified with the -s option will override an authmethod specified with the -A argument for communication with the sendhost.

The format for authmethod and a description of the currently available authentication methods are described with the -A argument.

-U

This option has been deprecated. Originally, it was used to specify the username to identify the AES key for authentication. All authentication options can now be specified using the -A argument. For the next several versions this option will report an error. Eventually, it may be reclaimed for another purpose.
 

Throughput Test Arguments:

The arguments were named to match their counterparts in Iperf as closely as possible.

Some of the options are not available for some of the throughput testers. BWCTL does not support UDP tests, changing the output format or changing the output units for either Nuttcp or Thrulay.

-T
Specify which throughput tester to use:
iperf
thrulay
nuttcp
Default:
None. Selects a tool that the client and server have in common
-S TOS

Set the TOS byte in the sending packets.
Default:
None.
-D DSCP

Set an RFC 2474 style DSCP value for the TOS byte in the sending packets. This can be set using a 6-bit numeric value in decimal, hex, or octal. Additionally, the following set of symbolic DSCP name constants are understood. (Example applications are taken from RFC 4594.)

-W window
Same as the -w option, except that the value is advisory. bwctl will attempt to dynamically determine the appropriate TCP window, based upon RTT information gathered from the control socket. If bwctl is unable to dynamically determine a window, the value window will be used.
Default:
Unset (system defaults)
-w window
Socket buffer sizes (bytes). For TCP, this sets the TCP window size. For UDP, this sets the socket receive buffer size.
Default:
Unset (system defaults)
 

Scheduling Arguments:

-a syncfuzz

Allow bwctl to run without a synchronized system clock. Use this to specify how far off the local clock is from UTC. bwctl prefers to have an NTP synchronized system clock to ensure the two endpoints of the test are actually agreeing to the same scheduled time window for test execution.

If two systems do NOT have a close enough notion of time, then the throughput test will eventually fail because one endpoint of the test will attempt to run at a different time than the other.

If the operating system supports the NTP system calls, and the system clock is determined to be unsynchronized, error messages will still be reported depending upon the value of the -e flag.

When calculating the time errors, this value will be aded in to account for the difference. The maximum time offset can be bounded on the server side, using the max_time_error directive, to prevent a denial of service attack. If set, the server will reject any requests to test with a peer that has too high a timestamp error.

Default:
Unset (Defaults to Set for systems without the NTP system calls)
-I interval
Specifies that bwctl should attempt to run a throughput test every interval seconds.
Default:
Unset. If it is unset, bwctl only runs the test once.
-L longest
Specifies the longest amount of time the client is willing to wait for a reservation window. When bwctl requests a test from the bwctld server, it specifies the earliest time and the latest time it is willing to accept. The latest time is determined by adding this longest option to the earliest time. The earliest time is essentially 'now'. The longest time is specified as a number of seconds.
Default:
If interval is set, the default is 50% of interval. Otherwise, the default is twice the test duration time but no smaller than 5 minutes. (See -t.)
-n nIntervals
Number of tests to perform if the -I option is set.
Default:
Continuous
-R alpha
Randomize the start time of the test within this alpha percent of the interval. Valid values for alpha are from 0-50. bwctl will attempt to run the test every interval +/- alpha percent. For example, if the interval is 300 seconds and alpha is set to 10 percent, then bwctl will attempt to run a test every 270-330 seconds. This option is only useful with the -I option.
Default:
0 (no randomness)
 

Output Arguments:

-d dir
Specifies directory for results files if the -p option is set.
-e facility
Syslog facility to log messages to.
Default:
LOG_USER
-f units
Specify the units for the tool to use when displaying the results. The accepted values for units are tool specific.
Iperf:
k
Kilobits per second

K
Kilobytes per second

m
Megabits per second

M
Megabytes per second

-h

Print a help message.
-p

Place test results in files. Print the filenames to stdout when results are complete.
-q

Quiet output. Output as little as possible.
-r

Send syslog messages to stderr. This is the default unless the -q option is specified so this option is only useful with the -q option.
-V

Print version information and exit.
-v

Verbose output. Specifying additional -v's increases the verbosity.
-x

Output sender (client) results as well as receiver results. By default, sender results are not output. If the -p option is specified, the sender results are placed in an additional file.
-y format
Specify the output format of the tool. The accepted values for format are tool specific.
Iperf:
c
[c]omma-separated output

bwctl -x -c somehost.example.com

Like the previous test, but also return the results from the sender side of the test.

bwctl -x -c somehost.example.com -s otherhost.example.com

Like the previous test, but with otherhost.example.com as the sender instead of local.

bwctl -t 30 -T iperf -s somehost.example.com

Run a 30 second TCP Iperf test with somehost.example.com as the sender and local as the receiver.

bwctl -I 3600 -R 10 -t 10 -u -b 10m -s somehost.example.com

Run a 10 second UDP test about every hour (3600 +/- 360 seconds) with the sender rate limited to 10 Mbits per second from somehost.example.com to local.

bwctl -s somehost.example.com AE AESKEY someuser

Run the default 10 second TCP test. Authenticate using the identity someuser. bwctl will prompt for a passphrase that will be used to create an AES key.

BWCTL Architecture

$Date: 2009-01-26 08:59:22 -0500 (Mon, 26 Jan 2009) $

Components Overview

In the general case, BWCTL works by having a bwctld process on each of the endpoint test systems. The bwctl client contacts each of those daemons and requests a test. That request includes an indication of the desired time period as well as a full parameterization of the desired Iperf, Nuttcp or Thrulay test. bwctld is responsible for implementing the policy and scheduling constraints.

General Case

bwctld has been developed as a classic accept/fork daemon. The master daemon process listens for new network connections and also manages the resources for all child bwctld processes. Once a connection comes in, bwctld forks a child process to handle that request. The child process deals with all encryption and communication issues with the client, as well as dealing with all static resource limits. Static resource limits are those not dependent upon what is currently happening on the node. For example, the request broker can easily determine if the given client is allowed to do UDP tests without talking to the master daemon. Once the request broker process determines the request is valid, it makes a request to the master daemon for the resources and time period requested by the client. If the master daemon has the resources available (including the open time period), it grants the request.

Scheduling Requests

The time period for the test is always requested by the client. It makes a request to the request broker process on each endpoint of the test in turn. The time period is requested by specifying two timestamps. The earliest time and the latest time the client is willing to settle for. The request broker either returns a tentative reservation with the first open time that will fulfill the parameters of the test or a request denied message. The client can then use the tentative reservation time as the earliest time in the request to the request broker on the other host. Eventually, an agreed upon time will be reached or the latest time will be reached. If the request broker can not fulfill the request before the latest time specified in the request, it will return a server too busy message. If the client gets the same time from both servers, it must then confirm the reservation with a start session message. The start session message must be received before a configurable timeout period and before the reservation time, or the server will disallow the reservation.

Scheduling Algorithm

The bwctld parent resource broker process holds the master schedule. When requests come in from clients, the request broker process does the non-global authorization checks and then passes the global authorization checks up to the resource broker including the request for a given time slot. The scheduling itself is simply a first-fit algorithm with limits imposed on how far it is willing to schedule into the future.

Each time slot that is requested is padded to allow for time synchronization issues. The algorithm for the padding is dynamic and depends upon the following factors:

The algorithm is:
Where A is a small constant. (Currently, one second in the code.)

This amount of time is padded before and after each time slot that is requested. The algorithm was designed to continue to work in the case when the test peer is not as well synchronized and is perhaps halfway around the globe.

The padding is placed before and after the test slot because there is 2 RTT of communication before and after each test. For well synchronized hosts that are fairly near one another, this algorithm usually provides 2-3 seconds of padding between each test (time slot). This could potentially be reduced by making the A constant smaller. That constant represents the amount of time it takes a host to context switch, start processes, and includes how quickly the throughput tester notices that its time is up. Experimentation has shown that even with 1 second of padding, the throughput testers sometimes need to be killed off.

Test Execution

Once the client sends the the start session message, the request broker forks off a peer agent that is responsible for verifying the time offset to the other endpoint of the test and initializing the communication socket that will be used to trade results of the test.

If the test endpoint systems have a reasonably close idea of the time, and they can communicate, the peer agent forks off the test process. The test process waits until the scheduled start time and then executes the desired throughput tester with the correct command line parameters. Note: Experience is showing that a closer integration with the testing process (Iperf, Nuttcp or Thrulay) may be needed in the future.

End User Workstation Configuration

In the event that the local host is one of the endpoints and there is no local bwctld running, bwctl will spawn additional processes to execute the local side of the test directly. In this case, a diagram of the processes involved would look like the following:

Local bwctld not available

The same basic communication takes place between the different processes in this alignment. The main difference is that the client has no need of a resource broker. This is the expected usage scenario for end user workstations to run tests to well defined BWCTL measurement beacons.

* The images above shows a dashed blue line around the processes that occur on each host.

It is used to configure the basic operation of the server. For example, what addresses and ports it should listen on, where it should send error messages, and where it should save files. .PP The policy rules for \fBbwctld\fR are configured using the \fBbwctld.limits\fR file; the details for configuring those policies are described in the bwctld.limits(5) manual page. .PP .lf 1 bwctld_conf_opts.man ."

If it is found elsewhere, a syntax error is reported. .IP \(bu Blank lines are treated as comment lines. .IP \(bu All other lines are used to set configuration options. The format of these lines is an initial keyword followed by a variable list of arguments, separated by whitespace. .RE .SH CONFIGURATION OPTIONS .TP .BI access_priority " priority" Syslog \fIpriority\fR to log access messages. .RS .IP Default: LOG_INFO .RE .TP .B allow_unsync Directs \fBbwctld\fR to continue accepting valid requests for throughput tests when the system clock is not synchronized. \fBbwctld\fR prefers to have an NTP synchronized system clock to ensure the two endpoints of the test are actually agreeing to the same scheduled time window for test execution. This option is used to bypass this requirement for systems that either do not have the NTP system calls, or prefer not to configure NTP. .RS .PP Note: if the difference between the system clocks on the two endpoints is too great, the eventual throughput test will fail when the endpoints attempt to run the test at different times. The threshold for this difference is controlled using the \fIsync_fuzz\fR option. (If you set allow_unsync, you should set \fIsync_fuzz\fR to a reasonable value for your system.) .PP .IP Default: unset (set if the operating system does have the NTP system calls) .RE .TP .BI auth_mode " authmode" Specify the authentication modes the server is willing to use for communication. \fIauth_mode\fR should be set as a character string, with any or all of the characters "AEO". The modes are: .RS .IP \fBA\fR [\fBA\fR]uthenticated. This mode encrypts the control connection. .IP \fBE\fR [\fBE\fR]ncrypted. This mode encrypts the control connection. If the test supports encryption, this mode will additionally encrypt the test stream. (Encryption of the test stream is not currently supported, so this mode is currently identical to authenticated.) .IP \fBO\fR [\fBO\fR]pen. No encryption of any kind is done. .PP The server can specify all the modes with which it is willing to communicate. The most strict mode that both the server and the client are willing to use will be selected. .IP Default: "AEO" .RE .TP .BI bottleneck_capacity " bottleneckcapacity" This value is used in the algorithm to dynamically set the TCP send/recv window sizes. This option is likely to be removed in the future once a dynamic \fIbottleneck_capacity\fR algorithm is incorporated into the code. (This option only really works when the local NIC is the bottleneck.) If this option is not specified, the dynamic window calculation requested by the \fB-W\fR option to \fBbwctl\fR is not done and the advisory value is used. .RS .IP Default: unset .RE .TP .BI control_timeout " controltimeout" Number of seconds to wait for protocol messages before timing out. This value should be significantly larger than what typical users specify for the \fB-I\fR flag of \fBbwctl\fR or \fBbwctl\fR will have to open a new control connection for each new test it requests. .RS .IP Default: 7200 (Picked to be the same as the default for TCP keepalive) .RE .TP .BI die_by " dieby" Number of seconds to wait for child processes to gracefully terminate before killing them with \fBSIGKILL\fR. This is in response to the master process receiving \fBSIGTERM\fR or \fBSIGHUP\fR. .RS .IP Default: 30 .RE .TP .BI facility " facility" Syslog \fIfacility\fR to log messages. .RS .IP Default: LOG_DAEMON .RE .TP .BI group " group" Specifies the gid the \fBbwctld\fR process should run as. \fIgroup\fR can be specified using a valid group name on the system or by using -gid. This option is only used if \fBbwctld\fR is started as root. .RS .IP Default: unset .RE .TP .BI iperf_cmd " iperfcmd" The path to the \fBIperf\fR command on the system. If the \fIiperf_cmd\fR does not contain a '/' character, then the PATH of the \fBbwctld\fR environment will be searched to find the \fBIperf\fR executable. .RS .IP Default: iperf .RE .TP .BI iperf_port " iperfport" The port number(s) that \fBIperf\fR receivers will use. Currently, \fBbwctld\fR simply cycles through this range linearly. \fIiperf_port\fR can be specified as a single valid port number or as a range as \fIlow\fR-\fIhigh\fR. The range must be specified as two valid port numbers with the '-' character separating them. Whitespace is not allowed within the \fIiperf_port\fR. For example, \fB"5001-5004"\fR would be valid, but \fB"5001 - 5004"\fR would be invalid. .RS .PP This value should be set to a range because it can take a few minutes for a port to become free after a test has run. If the port is not free when the next test starts, the test will fail. If set to a range, the daemon will cycle through them when starting tests, decreasing the chance that a port will still be open when the test starts. For best results, ensure that this range is different from that of nuttcp_port and thrulay_port. .PP .IP Default: 5001 .RE .TP .B log_location Directs the \fBbwctld\fR process to report source code file and line number information with error messages. This is a particularly useful option to set when sending in messages as part of a bug report. .RS .IP Default: unset .RE .TP .BI nuttcp_cmd " nuttcpcmd" The path to the \fBNuttcp\fR command on the system. If the \fInuttcp_cmd\fR does not contain a '/' character, then the PATH of the \fBbwctl\fR environment will be searched to find the \fBNuttcp\fR executable. .RS .IP Default: nuttcp .RE .TP .BI nuttcp_port " nuttcpport" The port number(s) that \fBNuttcp\fR receivers will use. Currently, \fBbwctld\fR simply cycles through this range linearly. \fInuttcp_port\fR can be specified as a single valid port number or as a range as \fIlow\fR-\fIhigh\fR. The range must be specified as two valid port numbers with the '-' character separating them. Whitespace is not allowed within the \fInuttcp_port\fR. For example, \fB"5001-5004"\fR would be valid, but \fB"5001 - 5004"\fR would be invalid. .RS .PP This value should be set to a range because it can take a few minutes for a port to become free after a test has run. If the port is not free when the next test starts, the test will fail. If set to a range, the daemon will cycle through them when starting tests, decreasing the chance that a port will still be open when the test starts. For best results, ensure that this range is different from that of iperf_port and thrulay_port. .PP .IP Default: 5001 .RE .TP .BI peer_port " 0 | lowport-highport" Specify the port range that will be used on the local host for peer connections to other .B bwctld servers. These connections are used to verify clock timing between the servers and to exchange test results. This is a required part of the protocol used by .B BWCTL to run tests. However, this option allows system administrators to limit these connections to a specific port range, which should allow .B BWCTL to work in a firewall environment. This option can be specified in two ways. First, as a 0, which would indicate that .B bwctld should allow the system to pick the port (ephemeral). Second, as a range. .I lowport must be a smaller value than .I highport and both numbers must be valid port values. (16-bit unsigned integer values) .RS .IP Default: 0 .RE .TP .BI post_hook " /path/to/script" Specifies a script to run after each bwctl session has finished. These hooks can be used to save the results into a database, track usage or any number of other tasks. You can specify as many hooks as you want by including multiple post_hook entries. .TP .BI priority " priority" Syslog \fIpriority\fR to log error messages. .RS .IP Default: LOG_ERR .RE .TP .B root_folly Disables the checks that disable \fBbwctld\fR if it is run with \fIroot\fR permissions. There are legitimate reasons to run \fBbwctld\fR as root, but it is risky. Forcing this additional option will make it less likely root permissions are accidently used. .RS .IP Default: unset .RE .TP .BI src_node " nodename:port" Specify the address and port on which \fBbwctld\fR will listen for requests. \fInodename\fR can be specified using a DNS name or using the textual representation of the address. It is possible to set the source address without setting the \fIport\fR by simply leaving off the ':' and \fIport\fR specification. If an IPv6 address is specified, note that the accepted format contains \fInodename\fR in square brackets as: [fe80::fe9f:62d8]. This ensures the port number is distinct from the address specification. .RS .IP Default: \fInodename\fR is wildcarded as any currently available address .br \fIport\fR is 4823 .RE .TP .BI sync_fuzz " syncfuzz" This value is added to the NTP error estimates to increase the tolerance of \fBbwctld\fR to incomplete NTP configurations, or if the NTP system calls are not available. If NTP is unavailable to \fBbwctld\fR it assumes the clock is accurate to within one second plus the value of \fIsync_fuzz\fR. This option is specified as a floating point number in seconds. For example, to indicate that the system is synchronized within one second, you could specify this option as 1.0. .RS .PP Practically, this option is used to determine the size of the time window buffer before and after each throughput test. .IP Default: 0.0 .RE .TP .BI thrulay_port " thrulayport" The port number(s) that \fBThrulay\fR receivers will use. Currently, \fBbwctld\fR simply cycles through this range linearly. \fIthrulay_port\fR can be specified as a single valid port number or as a range as \fIlow\fR-\fIhigh\fR. The range must be specified as two valid port numbers with the '-' character separating them. Whitespace is not allowed within the \fIthrulay_port\fR. For example, \fB"5001-5004"\fR would be valid, but \fB"5001 - 5004"\fR would be invalid. .RS .PP This value should be set to a range because it can take a few minutes for a port to become free after a test has run. If the port is not free when the next test starts, the test will fail. If set to a range, the daemon will cycle through them when starting tests, decreasing the chance that a port will still be open when the test starts. For best results, ensure that this range is different from that of iperf_port and nuttcp_port. .PP .IP Default: 5003 .RE .TP .BI user " user" Specifies the uid the \fBbwctld\fR process should run as. \fIuser\fR can be specified using a valid user name on the system or by using -uid. This option is only used if \fBbwctld\fR is started as root. If the given \fIuser\fR has \fIroot\fR permissions, the \fIroot_folly\fR option must also be specified. .RS .IP Default: unset .RE .TP .BI var_dir " vardir" Directory path where the bwctld.pid file will be placed. .RS .IP Default: Current directory .RE .lf 38 bwctld.conf.ms .RE .SH SEE ALSO bwctl(1), bwctld(8), bwctld.limits(5), bwctld.keys(5), and the \%http://e2epi.internet2.edu/bwctl/ web site. .PP For details on \fBIperf\fR, see the \%http://sourceforge.net/projects/iperf web site. .PP For details on \fBNuttcp\fR, see the \%http://www.wcisd.hpc.mil/nuttcp/Nuttcp-HOWTO.html web site. .PP For details on \fBThrulay\fR, see the \%http://e2epi.internet2.edu/thrulay/ web site. .SH ACKNOWLEDGMENTS This material is based in part on work supported by the National Science Foundation (NSF) under Grant No. ANI-0314723.

It allows the system administrator to allocate the resources in a variety of ways. .PP There are two parts to the policy configuration: .TP Authentication Who is making the request? This can be very specific to an individual user or it can be more general in that the connection is coming from some particular network. .TP Authorization Now that the connection has been generally identified, what will \fBbwctld\fR allow it to do? .PP The authentication is done by assigning a \fIuserclass\fR to each new connection as it comes in. Each \fIuserclass\fR has a set of limits associated with it. The \fIuserclass\fRes are hierarchical, so a connection must pass the limit restrictions of the given \fIuserclass\fR as well as all parent classes. .PP Within the \fBbwcltd.limits\fR file, \fIassign\fR lines are used to assign a \fIuserclass\fR to a given connection. \fIlimit\fR lines are used to define a \fIuserclass\fR and set the limits associated with that \fIuserclass\fR. The file is read sequentially, and it is not permitted to use a \fIclassname\fR before it is defined using a limit line. .PP The format of this file is: .RS .IP \(bu Comment lines are any line where the first non-whitespace character is '#'. These lines are counted to return line numbers in error messages but are otherwise ignored by \fBbwctld\fR. .IP \(bu Lines may be continued using the semi-standard '\\' character followed immediately by a newline. This is the only valid place for the '\\' character. If it is found elsewhere a syntax error is reported. .IP \(bu Blank lines are treated as comment lines. .IP \(bu All other lines must conform to the syntax of a \fIlimit\fR line or an \fIassign\fR line. .RE .SH CONFIGURATION OPTIONS .TP \fIlimit\fR This directive is used to define the \fIuserclass\fR hierarchy. It defines the \fIclassname\fR as well as the limits associated with that class. A \fIclassname\fR may only be defined once. The format of the \fIlimit\fR directive is: .PP .RS limit \fIclassname\fR with \fIlimtype\fR=\fIvalue\fR[,\fIlimtype\fR=\fIvalue\fR]* .PP \fIclassname\fR defines the name of the class with the given limits. Whitespace is used as a separator but is otherwise ignored. \fIclassname\fR may be used as a directory name component within \fBbwctld\fR, so take care not to use characters that would be invalid. (i.e. '*' or '/' would be particularly bad.) .PP \fIlimtype\fR and \fIvalue\fR indicate the particular type of limit and value to apply to this \fIuserclass\fR. The available settings for \fIlimtype\fR are: .TS li li li _ _ _ li l l . limtype valid values default allow_open_mode on/off on allow_tcp on/off on allow_udp on/off off bandwidth integer (b/s) 0 (unlimited) duration integer (seconds) 0 (unlimited) event_horizon integer (seconds) 0 (unlimited) max_time_error integer (seconds) 0 (unlimited) parent previously defined \fIclassname\fR null pending integer 0 (unlimited) .TE .TP .I allow_open_mode This limit is only useful if the class is assigned to a netmask. It is used to limit specific IP/netmask identities to only encrypted or authenticated mode transactions or to allow open mode. .TP .I allow_tcp Allow TCP \fBIperf\fR tests for \fIuserclass\fR. .TP .I allow_udp Allow UDP \fBIperf\fR tests for \fIuserclass\fR. .TP .I bandwidth Maximum amount of bandwidth to allow \fIuserclass\fR to use in a UDP \fBIperf\fR test. 0 indicates unlimited by policy, but remember this is checked all the way to the root of the hierarchy. (If you want an unlimited \fIuserclass\fR, your root must be unlimited, and the whole path down to the given \fIuserclass\fR.) .TP .I duration Maximum duration of a single \fBIperf\fR test for this \fIuserclass\fR. .TP .I event_horizon Maximum window into the future to look when trying to schedule a test for this \fIuserclass\fR. .TP .I max_time_error Maximum amount of time error to allow for tests in this class. The time error is the sum of the errors reported by NTP on the two involved systems. The larger the time error, the larger the duration of the reservation because the time error is used to ensure tests don't overlap. There is a limit on this to defend against DOS attacks where a client could report large errors to ensure other clients can not allocate test reservations. .TP .I parent The first \fIlimit\fR line cannot have a parent since none have been defined yet. As such, the first line defines the root of your class hierarchy. All remaining limit lines \fBMUST\fR assign a parent. (It is hierarchical, after all.) .TP .I pending Maximum number of \fIpending\fR reservations for this \fIuserclass\fR. .RE .TP \fIassign\fR The \fIassign\fR directive is used to assign a \fIuserclass\fR to a given connection. Basically, it authenticates the connection. The format of the \fIassign\fR directive is: .PP .RS assign \fIauthtype\fR [\fIargs\fR] \fIclassname\fR .PP \fIauthtype\fR identifies the type of authentication being used. Whitespace is used as a separator but is otherwise ignored. \fIclassname\fR must have been previously defined with the \fIlimit\fR directive earlier in the file. .PP The available settings for \fIauthtype\fR are: .TP .B default Used if no other assignment matches. It takes no \fIargs\fR. .TP .BI net " subnet" Assign a specific \fIsubnet\fR to a given \fIuserclass\fR. \fIsubnet\fR must be specified using VLSM notation (IP/nbits). The only \fIarg\fR is the \fIsubnet\fR. For example: .RS .TP 127.0.0.1/32 would match only the loopback IPv4 address. .TP ::1/128 would match only the loopback IPv6 address. .TP 192.168.1.0/24 would match all hosts on the 192.168.1.XXX network. .PP There must be no set bits in the non-masked portion of the address part of the \fIsubnet\fR specification. i.e., 192.168.1.1/24 would be an invalid \fIsubnet\fR due to the bit set in the fourth octet. .RE .TP .BI user " user" Assign a specific \fIuser\fR to a given \fIuserclass\fR. The \fIuser\fR must be defined in the \fBbwctld.keys\fR file. .SH AUTHENTICATION PROCESS \fBbwctld\fR determines if it should allow a connection from the client based upon the authentication mode of the request and the source IP address of the connection. If the client connection is in authenticated or encrypted mode, the daemon does not do any filtering based upon the source address of the connection. (See the \fB\-A\fR option to \fBbwctl\fR and the \fIauthmode\fR option in \fBbwctld.conf\fR.) In these modes, \fBbwctld\fR simply uses the \fIidentity\fR of the connection to determine the \fIuserclass\fR limits. If the connection is made in open mode, then \fBbwctld\fR first uses the source address to determine if \fBbwctld\fR should allow an open mode connection from that subnet at all. (This is the purpose of the \fIallow_open_mode limtype\fR described above.) If open mode is allowed from this subnet, then the \fIuserclass\fR is determined by the closest subnet match defined by the \fIassign net\fR lines in the \fBbwctld.limits\fR file. .SH EXAMPLES An initial \fIlimit\fR line might look like: .RS .HP limit root with \\ .br bandwidth=900m, \\ .br duration=0, \\ .br allow_udp=on, \\ .br allow_tcp=on, \\ .br allow_open_mode=off .RE .PP This would create a \fIuserclass\fR named \fBroot\fR. Because no \fIparent\fR is specified, this must be the first \fIuserclass\fR defined in the file. This \fIuserclass\fR has very liberal limits (UDP enabled with 900m limit). However, open mode authentication is not enabled for this \fIuserclass\fR, so the connections that get these limits must successfully authenticate using an AES key. .PP If an administrator also wants to create a \fIuserclass\fR that is used to deny all requests, they might add: .RS .HP limit jail with \\ .br parent=root, \\ .br allow_udp=off, \\ .br allow_tcp=off, \\ .br allow_open_mode=off .RE .PP This would create a \fIuserclass\fR named \fBjail\fR. Because UDP and TCP tests have both been denied, no tests will be allowed. Also, \fIallow_open_mode\fR is off, so initial connections that are not in authenticated or encrypted mode would be dropped immediately anyway. (It would not make much sense to assign a \fIuser\fR identity to this \fIuserclass\fR. If you don't want connections from a particular \fIuser\fR, the best thing to do is to remove that \fIuser\fR from the \fBbwctld.keys\fR file. .PP If the administrator wanted to allow a limited amount of open tests, they could define a \fIuserclass\fR like: .RS .HP limit open with \\ .br parent=root, \\ .br allow_open_mode=on, \\ .br allow_udp=off, \\ .br allow_tcp=on, \\ .br duration=30, \\ .br event_horizon=300, \\ .br pending=5 .RE .PP This could be used to allow TCP throughput tests by random connections. It limits those tests to 30 seconds in duration, and only allows them to be scheduled within the next 5 minutes (\fIevent_horizon\fR=300). Additionally, it only allows this \fIuserclass\fR to have 5 currently \fIpending\fR reservations. This ensures that this \fIuserclass\fR can only schedule 50% of the next 5 minutes. The advantage of this kind of setup is that the administrator can define other \fIuserclasses\fR with a larger \fIevent_horizon\fR allowing then to have priority over this class. (Suggestions for other methods of priority scheduling should be sent to bwctl-users@internet2.edu.) .PP Now, these three \fIuserclasses\fR might be assigned to specific connections in the following ways: .RS .PP # default open .br assign default \fBopen\fR .PP # badguys subnet .br assign net 192.168.1.0/24 \fBjail\fR .PP # network admins .br assign user joe \fBroot\fR .br assign user jim \fBroot\fR .br assign user bob \fBroot\fR .br .RE .PP This set of \fIassign\fR lines specifically denies access from any open mode connection from the \fBbadguys\fR subnet. It specifically allows access to authenticated or encrypted mode transactions that can authenticate as the \fIidentities\fR \fBjoe jim\fR or \fBbob\fR (even from the \fBbadguys\fR subnet). All other connections would match the \fIassign default\fR rule and get the limits associated with the \fBopen\fR \fIuserclass\fR. .SH SEE ALSO bwctl(1), bwctld(8), bwctld.limits(5), bwctld.keys(5), and the \%http://e2epi.internet2.edu/bwctl/ web site. .PP For details on \fBIperf\fR, see the \%http://sourceforge.net/projects/iperf web site. .PP For details on \fBNuttcp\fR, see the \%http://www.wcisd.hpc.mil/nuttcp/Nuttcp-HOWTO.html web site. .PP For details on \fBThrulay\fR, see the \%http://e2epi.internet2.edu/thrulay/ web site. .SH ACKNOWLEDGMENTS This material is based in part on work supported by the National Science Foundation (NSF) under Grant No. ANI-0314723.

Description: ." .SH NAME bwctl \- Client application to request throughput tests. .SH SYNOPSIS .B bwctl [\fIoptions\fR] \fI\-c recvhost \-s sendhost\fR .br .B bwctl [\fIoptions\fR] \fI\-c recvhost\fR .br .B bwctl [\fIoptions\fR] \fI\-s sendhost\fR .SH DESCRIPTION \fBbwctl\fR is a command line client application that is used to initiate throughput tests. .TP This version of \fBbwctl\fR is capable of initiating \fBIperf\fR, \fBNuttcp\fR, and \fBThrulay\fR tests. .PP .B bwctl works by contacting a \fBbwctld\fR daemon on both the receiving host and the sending host. \fBbwctld\fR manages and schedules the resources of the host it runs on. In the case where only one of the receiving host or sending host is specified, \fBbwctl\fR assumes the local host is the other endpoint. \fBbwctl\fR will attempt to contact a local \fBbwctld\fR if it can. If there is no local \fBbwctld\fR running, \fBbwctl\fR assumes the local host does not require policy controls and will execute the \fBbwctld\fR functionality required to run the test directly. .PP If cases where \fBbwctl\fR is directly running the throughput test on the host, there are several configuration options that are shared with \fBbwctld\fR. Those configuration options can be set using the bwctlrc(5) configuration file in a way very similar to the way they are specified in the bwctld.conf(5) file. .PP The \fBbwctl\fR client is used to request the desired type of throughput test. Furthermore, it requests \fIwhen\fR the test is wanted. \fBbwctld\fR on each endpoint either responds with a tentative reservation or a \fBtest denied\fR message. Once \fBbwctl\fR is able to get a matching reservation from both \fBbwctld\fR processes (one for each host involved in the test), it confirms the reservation. Then, the \fBbwctld\fR processes run the test and return the results. The results are returned to the client from both sides of the test from the respective \fBbwctld\fR processes. Additionally, the \fBbwctld\fR processes share the results from their respective side of the test with each other. .PP \fBBWCTL\fR (\fBbwctl\fR and \fBbwctld\fR) is used to enable non-specific throughput tests to hosts without having to give full user accounts on the given systems. Users want the ability to run throughput tests to determine the achievable or available bandwidth between a pair of hosts. It is often useful to test to multiple points along a network path to determine the network characteristics along that path. Typically, users who want to do this path decomposition have to directly contact the network/system administrators who control the hosts along the path. The administrator needs to either run half of the test for the user or give them a user account on the host. Also, network paths of interest are typically controlled by multiple administrators. These hurdles have made this kind of testing difficult in practice. .PP \fBBWCTL\fR was designed to help with this problem. It allows an administrator to configure a given host as an \fBIperf\fR, \fBThrulay\fR, or \fBNuttcp\fR endpoint. The endpoint can be a packet sender (e.g. \fBIperf\fR client) or a packet receiver (e.g. \fBIperf\fR server). It can be shared by multiple users without concern that those users will interfere with each other. Specific policy limits can be applied to specific users, and individual tests are scheduled so they will not interfere with each other. Additionally, full user accounts are not required for the users running the tests. .PP \fBBWCTL\fR allows the administrator to classify incoming connections based upon a user name and AES key combination or, alternatively, based upon an IP/netmask. Once the connection is classified, the \fBbwctld\fR can determine the exact type and intensities of througput tests that will be allowed. More information on the policy controls can be found in the bwctld(8) man page. .PP \fBBWCTL\fR makes use of a distributed scheduling algorithm. Each host maintains a schedule independently. As a client requests a test, the two endpoints are contacted and each \fBbwctld\fR server responds with the first available open schedule slot. This enables on-demand tests to co-exist with regularly scheduled tests since regularly scheduled tests are implemented by having the client request tests on regular intervals. Different priorities can be implemented using the \fIevent_horizon\fR configuration directive to \fBbwctld\fR. (By allowing clients that implement regularly scheduled tests to reserve their time slots further into the future.) .SH ARGUMENTS .SS Connection/Authentication Arguments: .TP \fB\-4\fR Forces bwctl to use IPv4 addresses only. .RS .IP Default: Unspecified (IPv6 is preferred). .RE .TP \fB\-6\fR Forces bwctl to use IPv6 addresses only. .RS .IP Default: Unspecified (IPv6 is preferred). .RE .TP \fB\-A\fR \fIauthmethod\fB \fIauthmethod\fR is used to specify the authentication method the \fBbwctl\fR client is willing to use for communication with the \fBbwctld\fR on the \fIsendhost\fR and \fIrecvhost\fR. The authentication options of \fBbwctl\fR are intended to be extensible. The communication from the \fBbwctl\fR client to each \fBbwctld\fR server may take different options for different types of authentication. If the \fIauthmethod\fR option is specified for either the \fB\-s\fR, or the \fB\-c\fR argument, it overrides the \fIauthmethod\fR specified with the \fB\-A\fR option for communication with that particular host. (Therefore, the \fB\-A\fR argument is really only useful if the same authentication can be used with both hosts.) .RS .PP Allowing different authentication methods for each connection should allow a client to use different authentication methods with different servers which should in turn allow cross-domain tests to occur more easily. .PP The format for \fIauthmethod\fR is: .PP \fIauthmode [authscheme schemeopts]\fR .TP \fIauthmode\fR Specifies the authentication mode the client is willing to speak with a server. It must be set as a character string with any or all of the characters "AEO". The modes are: .RS .IP \fBA\fR [\fBA\fR]uthenticated. This mode encrypts the control connection. .IP \fBE\fR [\fBE\fR]ncrypted. This mode encrypts the control connection. If the test supports encryption, this mode will additionally encrypt the test stream. (Encryption of the test stream is not currently supported, so this mode is currently identical to authenticated.) .IP \fBO\fR [\fBO\fR]pen. No encryption of any kind is done. .PP The client can specify all the modes with which it is willing to communicate. The most strict mode that both the server and the client are willing to use will be selected. .IP Default: "AEO" .RE .TP \fIauthscheme schemeopts\fR \fIauthscheme\fR indicates the authentication scheme that should be used to achieve the \fBauthenticated\fR or \fBencrypted\fR modes. \fIschemeopts\fR are a list of arguments specific to each particular authentication scheme. Supported \fIauthscheme\fR values follow (listed with the \fIschemeopts\fR each scheme requires): .RS .TP \fBAESKEY\fR \fIuserid [keyfile]\fR This is the initial "simple" shared secret (AES key) model. \fIuserid\fR is required to identify which shared secret the server and client should use. \fIkeyfile\fR optionally specifies a file to retrieve the AES key from. If \fIkeyfile\fR is not specified, the user will be prompted for a \fIpassphrase\fR. \fIkeyfile\fR can be generated using the aespasswd(1) application. .IP "Default:" Unauthenticated .RE .PP \fIauthscheme\fR and \fIschemeopts\fR are only needed if authenticated communication (\fBA\fR or \fBE\fR modes of \fIauthmode\fR) is wanted with \fIsendhost\fR and \fIrecvhost\fR. .RE .TP \fB\-B\fR \fIsrcaddr\fR Bind the local address of the client socket to \fIsrcaddr\fR. \fIsrcaddr\fR can be specified using a DNS name or using standard textual notations for the IP addresses. .RS .IP Default: Unspecified (wild-card address selection). .RE .TP \fB\-c\fR \fIrecvhost[:port] [authmethod]\fR Specifies the host that will run the \fBIperf\fR, \fBThrulay\fR or \fBNuttcp\fR server. The :port suffix is optional and is only needed if \fBbwctld\fR is being run on a non-default port number. If an IPv6 address is being specified, note that the accepted format contains the \fIrecvhost\fR portion of the specification in square brackets as: [fe80::fe9f:62d8]:4823. This ensures the port number is distinct from the address specification, and is not needed if the :port suffix is not being used. .RS .PP At least one of the \fB\-c\fR or \fB\-s\fR options must be specified. If one of them is not specified, it is assumed to be the local host. .PP \fIauthmethod\fR is a specifically ordered list of keywords that is only needed if authenticated communication is wanted with \fIrecvhost\fR. These keywords are used to describe the type of communication and authentication that should be used to contact the \fIrecvhost\fR. If \fIrecvhost\fR and \fIsendhost\fR share the same authentication methods and identities, it is possible to specify the authmethod for both \fIrecvhost\fR and \fIsendhost\fR using the \fB\-A\fR argument. An \fIauthmethod\fR specified with the \fB\-c\fR option will override an \fIauthmethod\fR specified with the \fB\-A\fR argument for communication with the \fIrecvhost\fR. .PP The format for \fIauthmethod\fR and a description of the currently available authentication methods are described with the \fB\-A\fR argument. .RE .TP \fB\-k\fR .br This option has been deprecated. Originally, it was used to specify the keyfile for authentication. All authentication options can now be specified using the \fB\-A\fR argument. For the next several versions this option will report an error. Eventually, it may be reclaimed for another purpose. .RE .TP \fB\-s\fR \fIsendhost[:port] [authmethod]\fR Specifies the host that will run the \fBIperf\fR, \fBThrulay\fR or \fBNuttcp\fR client. The :port suffix is optional and is only needed if \fBbwctld\fR is being run on a non-default port number. If an IPv6 address is being specified, note that the accepted format contains the \fIsendhost\fR portion of the specification in square brackets as: [fe80::fe9f:62d8]:4823. This ensures the port number is distinct from the address specification, and is not needed if the :port suffix is not being used. .RS .PP At least one of the \fB\-c\fR or \fB\-s\fR options must be specified. If one of them is not specified, it is assumed to be the \fIlocal\fR. .PP \fIauthmethod\fR is a specifically ordered list of keywords that is only needed if authenticated communication is wanted with \fIsendhost\fR. These keywords are used to describe the type of communication and authentication that should be used to contact the \fIsendhost\fR. If \fIrecvhost\fR and \fIsendhost\fR share the same authentication methods and identities, it is possible to specify the authmethod for both \fIrecvhost\fR and \fIsendhost\fR using the \fB\-A\fR argument. An \fIauthmethod\fR specified with the \fB\-s\fR option will override an \fIauthmethod\fR specified with the \fB\-A\fR argument for communication with the \fIsendhost\fR. .PP The format for \fIauthmethod\fR and a description of the currently available authentication methods are described with the \fB\-A\fR argument. .RE .TP \fB\-U\fR .br This option has been deprecated. Originally, it was used to specify the username to identify the AES key for authentication. All authentication options can now be specified using the \fB\-A\fR argument. For the next several versions this option will report an error. Eventually, it may be reclaimed for another purpose. .SS Throughput Test Arguments: The arguments were named to match their counterparts in \fBIperf\fR as closely as possible. .PP Some of the options are not available for some of the throughput testers. BWCTL does not support UDP tests, changing the output format or changing the output units for either \fBNuttcp\fR or \fBThrulay\fR. .TP \fB\-T\fR Specify which throughput tester to use: .RS .IP \fBiperf\fR .IP \fBthrulay\fR .IP \fBnuttcp\fR .IP Default: None. Selects a tool that the client and server have in common .RE .TP \fB\-S\fR \fITOS\fR .br Set the TOS byte in the sending packets. .IP Default: None. .RE .TP \fB\-D\fR \fIDSCP\fR .br Set an RFC 2474 style DSCP value for the TOS byte in the sending packets.

NAME

bwctld - Bandwidth Control server.  

SYNOPSIS

bwctld [ -a auth_mode ] [ -c conf_dir ] [ -e facility ] [ -f ] [ -G group ] [ -h ] [ -R var_dir ] [ -S nodename:port ] [ -U user ] [ -Z ]  

DESCRIPTION

bwctld is a server program designed to schedule and run Iperf, Thrulay or Nuttcp throughput tests. These tests can measure maximum TCP bandwidth, with various tunable options available, or, by doing a UDP test, he delay, jitter and datagram loss of a network.

Aside from actually running throughput tests, the main function of bwctld is to determine which tests are allowable based upon the policy restrictions configured by the system administrator.

bwctld was designed to be run as a stand-alone daemon process. It uses the classic accept/fork model of handling new requests.

Most of the command line options for bwctld have analogous options in the bwctld.conf file. The command line takes precedence.  

OPTIONS

-a auth_mode
Specify the authentication modes the server is willing to use for communication. auth_mode should be set as a character string with any or all of the characters "AEO". The modes are:
A
[A]uthenticated. This mode encrypts the control connection.
E
[E]ncrypted. This mode encrypts the control connection. If the test supports encryption, this mode will additionally encrypt the test stream. (Encryption of the test stream is not currently supported, so this mode is currently identical to authenticated.)
O
[O]pen. No encryption of any kind is done.

The server can specify all the modes with which it is willing to communicate. The most strict mode that both the server and the client are willing to use will be selected.

Default:
"AEO".
-c conf_dir
Specify the directory that holds the bwctld configuration files.
Default:
Current working directory.
-e facility
Syslog facility to which messages are logged.
Default:
LOG_DAEMON
-f
Enables the bwctld daemon to run with root permissions. There are legitimate reasons to run bwctld as root, but it is risky. Forcing this additional option will make it less likely root permissions are accidently used.
-G group
Specify the gid for the bwctld process. group can be specified using a valid group name or by using -gid. This option is only used if bwctld is started as root.
-h
Print a help message.
-R var_dir
Specify the directory to hold the bwctld.pid file.
Default:
Current directory
-S nodename:port
Specify the address and port on which bwctld will listen for requests. nodename can be specified using a DNS name or using the textual representation of the address. It is possible to set the source address without setting the port simply by leaving off the ':' and port specification. If an IPv6 address is specified, note that the accepted format contains nodename in square brackets, such as: [fe80::fe9f:62d8]. This ensures the port number is distinct from the address specification.
Default:
nodename is wildcarded as any currently available address. port is 4823.
-U user
Specify the uid for the bwctld process. user can be specified using a valid user name or by using -uid. This option is only used if bwctld is started as root.
-Z
Run the master bwctld process in the foreground. In this mode, error messages are printed to stderr as well as being sent to syslog. Also, normal terminal controls are available. (i.e., <Cntr-C> will cause the daemon to kill it's child processes and exit.) This is useful for debugging.

 

REQUIREMENTS

The bwctld daemon prefers a reasonably synchronized clock. It is scheduling tests and needs to be sure it has the same idea of when a test should take place as does the peer test system. Therefore, bwctld attempts to use NTP specific system calls to determine the accuracy of the local clock. If those system calls are unavailable, or the administrator has set the allow_unsync option in the bwctld.conf file, then bwctld will blindly accept tests assuming the clock is synchronized to within the sync_fuzz value that is also defined in the bwctld.conf file. If this assumption does not hold true, then the test will eventually fail. Unfortunately, because the time offset is not detected early, this test will have taken up a schedule slot.

NAME

bwctlrc - Bandwidth Control configuration file  

DESCRIPTION

The bwctlrc file is a configuration file for the bwctl(8) program. If a test is requested using bwctl, and there is not a local bwctld(8) running, bwctl will spawn its own copy of bwctld. This configuration file is used to configure the basic operation of the automatically spawned server. For example, it can be used to configure whether to allow the local clock to be unsynchroznied, or where the iperf command is located.

This file can be placed in ~/.bwctlrc, where it will be automatically read by bwctl when it spawns off a bwctld. If the file is put elsewhere, the BWCTLRC environmental variable can be set to the path to the file and bwctl will read it.

The format of this file is:

*
Comment lines are any line where the first non-whitespace character is '#'. These lines are counted for the purposes of returning line numbers in error messages but are otherwise ignored by the spawned bwctld.
*
Lines may be continued using the semi-standard '\' character followed immediately by a newline character. This is the only valid place for the '\' character. If it is found elsewhere, a syntax error is reported.
*
Blank lines are treated as comment lines.
*
All other lines are used to set configuration options. The format of these lines is an initial keyword followed by a variable list of arguments, separated by whitespace.
 

CONFIGURATION OPTIONS

access_priority priority
Syslog priority to log access messages.
Default:
LOG_INFO
allow_unsync
Directs bwctld to continue accepting valid requests for throughput tests when the system clock is not synchronized. bwctld prefers to have an NTP synchronized system clock to ensure the two endpoints of the test are actually agreeing to the same scheduled time window for test execution. This option is used to bypass this requirement for systems that either do not have the NTP system calls, or prefer not to configure NTP.

Note: if the difference between the system clocks on the two endpoints is too great, the eventual throughput test will fail when the endpoints attempt to run the test at different times. The threshold for this difference is controlled using the sync_fuzz option. (If you set allow_unsync, you should set sync_fuzz to a reasonable value for your system.)

Default:
unset (set if the operating system does have the NTP system calls)
auth_mode authmode
Specify the authentication modes the server is willing to use for communication. auth_mode should be set as a character string, with any or all of the characters "AEO". The modes are:
A
[A]uthenticated. This mode encrypts the control connection.
E
[E]ncrypted. This mode encrypts the control connection. If the test supports encryption, this mode will additionally encrypt the test stream. (Encryption of the test stream is not currently supported, so this mode is currently identical to authenticated.)
O
[O]pen. No encryption of any kind is done.

The server can specify all the modes with which it is willing to communicate. The most strict mode that both the server and the client are willing to use will be selected.

Default:
"AEO"
bottleneck_capacity bottleneckcapacity
This value is used in the algorithm to dynamically set the TCP send/recv window sizes. This option is likely to be removed in the future once a dynamic bottleneck_capacity algorithm is incorporated into the code. (This option only really works when the local NIC is the bottleneck.) If this option is not specified, the dynamic window calculation requested by the -W option to bwctl is not done and the advisory value is used.
Default:
unset
control_timeout controltimeout
Number of seconds to wait for protocol messages before timing out. This value should be significantly larger than what typical users specify for the -I flag of bwctl or bwctl will have to open a new control connection for each new test it requests.
Default:
7200 (Picked to be the same as the default for TCP keepalive)
die_by dieby
Number of seconds to wait for child processes to gracefully terminate before killing them with SIGKILL. This is in response to the master process receiving SIGTERM or SIGHUP.
Default:
30
facility facility
Syslog facility to log messages.
Default:
LOG_DAEMON
group group
Specifies the gid the bwctld process should run as. group can be specified using a valid group name on the system or by using -gid. This option is only used if bwctld is started as root.
Default:
unset
iperf_cmd iperfcmd
The path to the Iperf command on the system. If the iperf_cmd does not contain a '/' character, then the PATH of the bwctld environment will be searched to find the Iperf executable.
Default:
iperf
iperf_port iperfport
The port number(s) that Iperf receivers will use. Currently, bwctld simply cycles through this range linearly. iperf_port can be specified as a single valid port number or as a range as low-high. The range must be specified as two valid port numbers with the '-' character separating them. Whitespace is not allowed within the iperf_port. For example, "5001-5004" would be valid, but "5001 - 5004" would be invalid.

This value should be set to a range because it can take a few minutes for a port to become free after a test has run. If the port is not free when the next test starts, the test will fail. If set to a range, the daemon will cycle through them when starting tests, decreasing the chance that a port will still be open when the test starts. For best results, ensure that this range is different from that of nuttcp_port and thrulay_port.

Default:
5001
log_location
Directs the bwctld process to report source code file and line number information with error messages. This is a particularly useful option to set when sending in messages as part of a bug report.
Default:
unset
nuttcp_cmd nuttcpcmd
The path to the Nuttcp command on the system. If the nuttcp_cmd does not contain a '/' character, then the PATH of the bwctl environment will be searched to find the Nuttcp executable.
Default:
nuttcp
nuttcp_port nuttcpport
The port number(s) that Nuttcp receivers will use. Currently, bwctld simply cycles through this range linearly. nuttcp_port can be specified as a single valid port number or as a range as low-high. The range must be specified as two valid port numbers with the '-' character separating them. Whitespace is not allowed within the nuttcp_port. For example, "5001-5004" would be valid, but "5001 - 5004" would be invalid.

This value should be set to a range because it can take a few minutes for a port to become free after a test has run. If the port is not free when the next test starts, the test will fail. If set to a range, the daemon will cycle through them when starting tests, decreasing the chance that a port will still be open when the test starts. For best results, ensure that this range is different from that of iperf_port and thrulay_port.

Default:
5001
peer_port 0 | lowport-highport
Specify the port range that will be used on the local host for peer connections to other bwctld servers. These connections are used to verify clock timing between the servers and to exchange test results. This is a required part of the protocol used by BWCTL to run tests. However, this option allows system administrators to limit these connections to a specific port range, which should allow BWCTL to work in a firewall environment. This option can be specified in two ways. First, as a 0, which would indicate that bwctld should allow the system to pick the port (ephemeral). Second, as a range. lowport must be a smaller value than highport and both numbers must be valid port values. (16-bit unsigned integer values)
Default:
0
post_hook /path/to/script
Specifies a script to run after each bwctl session has finished. These hooks can be used to save the results into a database, track usage or any number of other tasks. You can specify as many hooks as you want by including multiple post_hook entries.
priority priority
Syslog priority to log error messages.
Default:
LOG_ERR
root_folly
Disables the checks that disable bwctld if it is run with root permissions. There are legitimate reasons to run bwctld as root, but it is risky. Forcing this additional option will make it less likely root permissions are accidently used.
Default:
unset
src_node nodename:port
Specify the address and port on which bwctld will listen for requests. nodename can be specified using a DNS name or using the textual representation of the address. It is possible to set the source address without setting the port by simply leaving off the ':' and port specification. If an IPv6 address is specified, note that the accepted format contains nodename in square brackets as: [fe80::fe9f:62d8]. This ensures the port number is distinct from the address specification.
Default:
nodename is wildcarded as any currently available address
port is 4823
sync_fuzz syncfuzz
This value is added to the NTP error estimates to increase the tolerance of bwctld to incomplete NTP configurations, or if the NTP system calls are not available. If NTP is unavailable to bwctld it assumes the clock is accurate to within one second plus the value of sync_fuzz. This option is specified as a floating point number in seconds. For example, to indicate that the system is synchronized within one second, you could specify this option as 1.0.

Practically, this option is used to determine the size of the time window buffer before and after each throughput test.

Default:
0.0
thrulay_port thrulayport
The port number(s) that Thrulay receivers will use. Currently, bwctld simply cycles through this range linearly. thrulay_port can be specified as a single valid port number or as a range as low-high. The range must be specified as two valid port numbers with the '-' character separating them. Whitespace is not allowed within the thrulay_port. For example, "5001-5004" would be valid, but "5001 - 5004" would be invalid.

This value should be set to a range because it can take a few minutes for a port to become free after a test has run. If the port is not free when the next test starts, the test will fail. If set to a range, the daemon will cycle through them when starting tests, decreasing the chance that a port will still be open when the test starts. For best results, ensure that this range is different from that of iperf_port and nuttcp_port.

Default:
5003
user user
Specifies the uid the bwctld process should run as. user can be specified using a valid user name on the system or by using -uid. This option is only used if bwctld is started as root. If the given user has root permissions, the root_folly option must also be specified.
Default:
unset
var_dir vardir
Directory path where the bwctld.pid file will be placed.
Default:
Current directory

These tests can measure maximum TCP bandwidth, with various tunable options available, or, by doing a UDP test, he delay, jitter and datagram loss of a network. .PP Aside from actually running throughput tests, the main function of \fBbwctld\fR is to determine which tests are allowable based upon the policy restrictions configured by the system administrator. .PP \fBbwctld\fR was designed to be run as a stand-alone daemon process. It uses the classic accept/fork model of handling new requests. .PP Most of the command line options for \fBbwctld\fR have analogous options in the \fBbwctld.conf\fR file. The command line takes precedence. .SH OPTIONS .TP .BI \-a " auth_mode" Specify the authentication modes the server is willing to use for communication. \fIauth_mode\fR should be set as a character string with any or all of the characters "AEO". The modes are: .RS .IP \fBA\fR [\fBA\fR]uthenticated. This mode encrypts the control connection. .IP \fBE\fR [\fBE\fR]ncrypted. This mode encrypts the control connection. If the test supports encryption, this mode will additionally encrypt the test stream. (Encryption of the test stream is not currently supported, so this mode is currently identical to authenticated.) .IP \fBO\fR [\fBO\fR]pen. No encryption of any kind is done. .PP The server can specify all the modes with which it is willing to communicate. The most strict mode that both the server and the client are willing to use will be selected. .IP Default: "AEO". .RE .TP .BI \-c " conf_dir" Specify the directory that holds the \fBbwctld\fR configuration files. .RS .IP Default: Current working directory. .RE .TP .BI \-e " facility" Syslog \fIfacility\fR to which messages are logged. .RS .IP Default: LOG_DAEMON .RE .TP .B \-f Enables the \fBbwctld\fR daemon to run with \fIroot\fR permissions. There are legitimate reasons to run \fBbwctld\fR as root, but it is risky. Forcing this additional option will make it less likely root permissions are accidently used. .TP .BI \-G " group" Specify the gid for the \fBbwctld\fR process. \fIgroup\fR can be specified using a valid group name or by using \-gid. This option is only used if \fBbwctld\fR is started as root. .TP .B \-h Print a help message. .TP .BI \-R " var_dir" Specify the directory to hold the bwctld.pid file. .RS .IP Default: Current directory .RE .TP .BI \-S " nodename:port" Specify the address and port on which \fBbwctld\fR will listen for requests. \fInodename\fR can be specified using a DNS name or using the textual representation of the address. It is possible to set the source address without setting the \fIport\fR simply by leaving off the ':' and \fIport\fR specification. If an IPv6 address is specified, note that the accepted format contains \fInodename\fR in square brackets, such as: [fe80::fe9f:62d8]. This ensures the port number is distinct from the address specification. .RS .IP Default: \fInodename\fR is wildcarded as any currently available address. \fIport\fR is 4823. .RE .TP .BI \-U " user" Specify the uid for the \fBbwctld\fR process. \fIuser\fR can be specified using a valid user name or by using \-uid. This option is only used if \fBbwctld\fR is started as root. .TP .B \-Z Run the master \fBbwctld\fR process in the foreground. In this mode, error messages are printed to stderr as well as being sent to syslog. Also, normal terminal controls are available. (i.e., will cause the daemon to kill it's child processes and exit.) This is useful for debugging. .SH REQUIREMENTS The \fBbwctld\fR daemon prefers a reasonably synchronized clock. It is scheduling tests and needs to be sure it has the same idea of when a test should take place as does the peer test system. Therefore, \fBbwctld\fR attempts to use NTP specific system calls to determine the accuracy of the local clock. If those system calls are unavailable, or the administrator has set the \fIallow_unsync\fR option in the \fBbwctld.conf\fR file, then \fBbwctld\fR will blindly accept tests assuming the clock is synchronized to within the \fIsync_fuzz\fR value that is also defined in the \fBbwctld.conf\fR file. If this assumption does not hold true, then the test will eventually fail. Unfortunately, because the time offset is not detected early, this test will have taken up a schedule slot. .SH FILES bwctld.pid .br bwctld.conf .br bwctld.limits .br bwctld.keys .SH SEE ALSO There are more details on configuring the \fBbwctld\fR daemon in the bwctld.conf(5) manual page.

NAME

bwctld.limits - Bandwidth Control daemon policy configuration file  

DESCRIPTION

The bwctld.limits file is used to define the policy configuration for the bwctld program. It allows the system administrator to allocate the resources in a variety of ways.

There are two parts to the policy configuration:

Authentication
Who is making the request? This can be very specific to an individual user or it can be more general in that the connection is coming from some particular network.
Authorization
Now that the connection has been generally identified, what will bwctld allow it to do?

The authentication is done by assigning a userclass to each new connection as it comes in. Each userclass has a set of limits associated with it. The userclasses are hierarchical, so a connection must pass the limit restrictions of the given userclass as well as all parent classes.

Within the bwcltd.limits file, assign lines are used to assign a userclass to a given connection. limit lines are used to define a userclass and set the limits associated with that userclass. The file is read sequentially, and it is not permitted to use a classname before it is defined using a limit line.

The format of this file is:

*
Comment lines are any line where the first non-whitespace character is '#'. These lines are counted to return line numbers in error messages but are otherwise ignored by bwctld.
*
Lines may be continued using the semi-standard '\' character followed immediately by a newline. This is the only valid place for the '\' character. If it is found elsewhere a syntax error is reported.
*
Blank lines are treated as comment lines.
*
All other lines must conform to the syntax of a limit line or an assign line.
 

CONFIGURATION OPTIONS

limit
This directive is used to define the userclass hierarchy. It defines the classname as well as the limits associated with that class. A classname may only be defined once. The format of the limit directive is:

limit classname with limtype=value[,limtype=value]*

classname defines the name of the class with the given limits. Whitespace is used as a separator but is otherwise ignored. classname may be used as a directory name component within bwctld, so take care not to use characters that would be invalid. (i.e. '*' or '/' would be particularly bad.)

limtype and value indicate the particular type of limit and value to apply to this userclass. The available settings for limtype are:

allow_open_modeon/offon
allow_tcpon/offon
allow_udpon/offoff
bandwidthinteger (b/s)0 (unlimited)
durationinteger (seconds)0 (unlimited)
event_horizoninteger (seconds)0 (unlimited)
max_time_errorinteger (seconds)0 (unlimited)
parentpreviously defined classnamenull
pendinginteger0 (unlimited)

allow_open_mode
This limit is only useful if the class is assigned to a netmask. It is used to limit specific IP/netmask identities to only encrypted or authenticated mode transactions or to allow open mode.
allow_tcp
Allow TCP Iperf tests for userclass.
allow_udp
Allow UDP Iperf tests for userclass.
bandwidth
Maximum amount of bandwidth to allow userclass to use in a UDP Iperf test. 0 indicates unlimited by policy, but remember this is checked all the way to the root of the hierarchy. (If you want an unlimited userclass, your root must be unlimited, and the whole path down to the given userclass.)
duration
Maximum duration of a single Iperf test for this userclass.
event_horizon
Maximum window into the future to look when trying to schedule a test for this userclass.
max_time_error
Maximum amount of time error to allow for tests in this class. The time error is the sum of the errors reported by NTP on the two involved systems. The larger the time error, the larger the duration of the reservation because the time error is used to ensure tests don't overlap. There is a limit on this to defend against DOS attacks where a client could report large errors to ensure other clients can not allocate test reservations.
parent
The first limit line cannot have a parent since none have been defined yet. As such, the first line defines the root of your class hierarchy. All remaining limit lines MUST assign a parent. (It is hierarchical, after all.)
pending
Maximum number of pending reservations for this userclass.
assign
The assign directive is used to assign a userclass to a given connection. Basically, it authenticates the connection. The format of the assign directive is:

assign authtype [args] classname

authtype identifies the type of authentication being used. Whitespace is used as a separator but is otherwise ignored. classname must have been previously defined with the limit directive earlier in the file.

The available settings for authtype are:

default
Used if no other assignment matches. It takes no args.
net subnet
Assign a specific subnet to a given userclass. subnet must be specified using VLSM notation (IP/nbits). The only arg is the subnet. For example:
127.0.0.1/32
would match only the loopback IPv4 address.
::1/128
would match only the loopback IPv6 address.
192.168.1.0/24
would match all hosts on the 192.168.1.XXX network.

There must be no set bits in the non-masked portion of the address part of the subnet specification. i.e., 192.168.1.1/24 would be an invalid subnet due to the bit set in the fourth octet.

user user
Assign a specific user to a given userclass. The user must be defined in the bwctld.keys file.
 

AUTHENTICATION PROCESS

bwctld determines if it should allow a connection from the client based upon the authentication mode of the request and the source IP address of the connection. If the client connection is in authenticated or encrypted mode, the daemon does not do any filtering based upon the source address of the connection. (See the -A option to bwctl and the authmode option in bwctld.conf.) In these modes, bwctld simply uses the identity of the connection to determine the userclass limits. If the connection is made in open mode, then bwctld first uses the source address to determine if bwctld should allow an open mode connection from that subnet at all. (This is the purpose of the allow_open_mode limtype described above.) If open mode is allowed from this subnet, then the userclass is determined by the closest subnet match defined by the assign net lines in the bwctld.limits file.  

EXAMPLES

An initial limit line might look like:
limit root with \
bandwidth=900m, \
duration=0, \
allow_udp=on, \
allow_tcp=on, \
allow_open_mode=off

This would create a userclass named root. Because no parent is specified, this must be the first userclass defined in the file. This userclass has very liberal limits (UDP enabled with 900m limit). However, open mode authentication is not enabled for this userclass, so the connections that get these limits must successfully authenticate using an AES key.

If an administrator also wants to create a userclass that is used to deny all requests, they might add:

limit jail with \
parent=root, \
allow_udp=off, \
allow_tcp=off, \
allow_open_mode=off

This would create a userclass named jail. Because UDP and TCP tests have both been denied, no tests will be allowed. Also, allow_open_mode is off, so initial connections that are not in authenticated or encrypted mode would be dropped immediately anyway. (It would not make much sense to assign a user identity to this userclass. If you don't want connections from a particular user, the best thing to do is to remove that user from the bwctld.keys file.

If the administrator wanted to allow a limited amount of open tests, they could define a userclass like:

limit open with \
parent=root, \
allow_open_mode=on, \
allow_udp=off, \
allow_tcp=on, \
duration=30, \
event_horizon=300, \
pending=5

This could be used to allow TCP throughput tests by random connections. It limits those tests to 30 seconds in duration, and only allows them to be scheduled within the next 5 minutes (event_horizon=300). Additionally, it only allows this userclass to have 5 currently pending reservations. This ensures that this userclass can only schedule 50% of the next 5 minutes. The advantage of this kind of setup is that the administrator can define other userclasses with a larger event_horizon allowing then to have priority over this class. (Suggestions for other methods of priority scheduling should be sent to bwctl-users@internet2.edu.)

Now, these three userclasses might be assigned to specific connections in the following ways:

# default open
assign default open

# badguys subnet
assign net 192.168.1.0/24 jail

# network admins
assign user joe root
assign user jim root
assign user bob root

This set of assign lines specifically denies access from any open mode connection from the badguys subnet. It specifically allows access to authenticated or encrypted mode transactions that can authenticate as the identities joe jim or bob (even from the badguys subnet). All other connections would match the assign default rule and get the limits associated with the open userclass.

This option is used to bypass this requirement for systems that either do not have the NTP system calls, or prefer not to configure NTP. .RS .PP Note: if the difference between the system clocks on the two endpoints is too great, the eventual throughput test will fail when the endpoints attempt to run the test at different times. The threshold for this difference is controlled using the \fIsync_fuzz\fR option. (If you set allow_unsync, you should set \fIsync_fuzz\fR to a reasonable value for your system.) .PP .IP Default: unset (set if the operating system does have the NTP system calls) .RE .TP .BI auth_mode " authmode" Specify the authentication modes the server is willing to use for communication. \fIauth_mode\fR should be set as a character string, with any or all of the characters "AEO". The modes are: .RS .IP \fBA\fR [\fBA\fR]uthenticated. This mode encrypts the control connection. .IP \fBE\fR [\fBE\fR]ncrypted. This mode encrypts the control connection. If the test supports encryption, this mode will additionally encrypt the test stream.

The most strict mode that both the server and the client are willing to use will be selected. .IP Default: "AEO" .RE .TP .BI bottleneck_capacity " bottleneckcapacity" This value is used in the algorithm to dynamically set the TCP send/recv window sizes. This option is likely to be removed in the future once a dynamic \fIbottleneck_capacity\fR algorithm is incorporated into the code. (This option only really works when the local NIC is the bottleneck.) If this option is not specified, the dynamic window calculation requested by the \fB-W\fR option to \fBbwctl\fR is not done and the advisory value is used. .RS .IP Default: unset .RE .TP .BI control_timeout " controltimeout" Number of seconds to wait for protocol messages before timing out. This value should be significantly larger than what typical users specify for the \fB-I\fR flag of \fBbwctl\fR or \fBbwctl\fR will have to open a new control connection for each new test it requests. .RS .IP Default: 7200 (Picked to be the same as the default for TCP keepalive) .RE .TP .BI die_by " dieby" Number of seconds to wait for child processes to gracefully terminate before killing them with \fBSIGKILL\fR. This is in response to the master process receiving \fBSIGTERM\fR or \fBSIGHUP\fR. .RS .IP Default: 30 .RE .TP .BI facility " facility" Syslog \fIfacility\fR to log messages. .RS .IP Default: LOG_DAEMON .RE .TP .BI group " group" Specifies the gid the \fBbwctld\fR process should run as. \fIgroup\fR can be specified using a valid group name on the system or by using -gid. This option is only used if \fBbwctld\fR is started as root. .RS .IP Default: unset .RE .TP .BI iperf_cmd " iperfcmd" The path to the \fBIperf\fR command on the system.

Currently, \fBbwctld\fR simply cycles through this range linearly. \fIiperf_port\fR can be specified as a single valid port number or as a range as \fIlow\fR-\fIhigh\fR. The range must be specified as two valid port numbers with the '-' character separating them. Whitespace is not allowed within the \fIiperf_port\fR. For example, \fB"5001-5004"\fR would be valid, but \fB"5001 - 5004"\fR would be invalid. .RS .PP This value should be set to a range because it can take a few minutes for a port to become free after a test has run. If the port is not free when the next test starts, the test will fail. If set to a range, the daemon will cycle through them when starting tests, decreasing the chance that a port will still be open when the test starts.

These connections are used to verify clock timing between the servers and to exchange test results. This is a required part of the protocol used by .B BWCTL to run tests. However, this option allows system administrators to limit these connections to a specific port range, which should allow .B BWCTL to work in a firewall environment. This option can be specified in two ways. First, as a 0, which would indicate that .B bwctld should allow the system to pick the port (ephemeral). Second, as a range. .I lowport must be a smaller value than .I highport and both numbers must be valid port values. (16-bit unsigned integer values) .RS .IP Default: 0 .RE .TP .BI post_hook " /path/to/script" Specifies a script to run after each bwctl session has finished. These hooks can be used to save the results into a database, track usage or any number of other tasks. You can specify as many hooks as you want by including multiple post_hook entries. .TP .BI priority " priority" Syslog \fIpriority\fR to log error messages. .RS .IP Default: LOG_ERR .RE .TP .B root_folly Disables the checks that disable \fBbwctld\fR if it is run with \fIroot\fR permissions. There are legitimate reasons to run \fBbwctld\fR as root, but it is risky. Forcing this additional option will make it less likely root permissions are accidently used. .RS .IP Default: unset .RE .TP .BI src_node " nodename:port" Specify the address and port on which \fBbwctld\fR will listen for requests. \fInodename\fR can be specified using a DNS name or using the textual representation of the address. It is possible to set the source address without setting the \fIport\fR by simply leaving off the ':' and \fIport\fR specification. If an IPv6 address is specified, note that the accepted format contains \fInodename\fR in square brackets as: [fe80::fe9f:62d8]. This ensures the port number is distinct from the address specification. .RS .IP Default: \fInodename\fR is wildcarded as any currently available address .br \fIport\fR is 4823 .RE .TP .BI sync_fuzz " syncfuzz" This value is added to the NTP error estimates to increase the tolerance of \fBbwctld\fR to incomplete NTP configurations, or if the NTP system calls are not available. If NTP is unavailable to \fBbwctld\fR it assumes the clock is accurate to within one second plus the value of \fIsync_fuzz\fR. This option is specified as a floating point number in seconds. For example, to indicate that the system is synchronized within one second, you could specify this option as 1.0. .RS .PP Practically, this option is used to determine the size of the time window buffer before and after each throughput test. .IP Default: 0.0 .RE .TP .BI thrulay_port " thrulayport" The port number(s) that \fBThrulay\fR receivers will use.

NAME

bwctld.conf - Bandwidth Control daemon configuration file  

DESCRIPTION

The bwctld.conf file is the configuration file for the bwctld(8) program. It is used to configure the basic operation of the server. For example, what addresses and ports it should listen on, where it should send error messages, and where it should save files.

The policy rules for bwctld are configured using the bwctld.limits file; the details for configuring those policies are described in the bwctld.limits(5) manual page.

The format of this file is:

*
Comment lines are any line where the first non-whitespace character is '#'. These lines are counted for the purposes of returning line numbers in error messages but are otherwise ignored by the spawned bwctld.
*
Lines may be continued using the semi-standard '\' character followed immediately by a newline character. This is the only valid place for the '\' character. If it is found elsewhere, a syntax error is reported.
*
Blank lines are treated as comment lines.
*
All other lines are used to set configuration options. The format of these lines is an initial keyword followed by a variable list of arguments, separated by whitespace.
 

CONFIGURATION OPTIONS

access_priority priority
Syslog priority to log access messages.
Default:
LOG_INFO
allow_unsync
Directs bwctld to continue accepting valid requests for throughput tests when the system clock is not synchronized. bwctld prefers to have an NTP synchronized system clock to ensure the two endpoints of the test are actually agreeing to the same scheduled time window for test execution. This option is used to bypass this requirement for systems that either do not have the NTP system calls, or prefer not to configure NTP.

Note: if the difference between the system clocks on the two endpoints is too great, the eventual throughput test will fail when the endpoints attempt to run the test at different times. The threshold for this difference is controlled using the sync_fuzz option. (If you set allow_unsync, you should set sync_fuzz to a reasonable value for your system.)

Default:
unset (set if the operating system does have the NTP system calls)
auth_mode authmode
Specify the authentication modes the server is willing to use for communication. auth_mode should be set as a character string, with any or all of the characters "AEO". The modes are:
A
[A]uthenticated. This mode encrypts the control connection.
E
[E]ncrypted. This mode encrypts the control connection. If the test supports encryption, this mode will additionally encrypt the test stream. (Encryption of the test stream is not currently supported, so this mode is currently identical to authenticated.)
O
[O]pen. No encryption of any kind is done.

The server can specify all the modes with which it is willing to communicate. The most strict mode that both the server and the client are willing to use will be selected.

Default:
"AEO"
bottleneck_capacity bottleneckcapacity
This value is used in the algorithm to dynamically set the TCP send/recv window sizes. This option is likely to be removed in the future once a dynamic bottleneck_capacity algorithm is incorporated into the code. (This option only really works when the local NIC is the bottleneck.) If this option is not specified, the dynamic window calculation requested by the -W option to bwctl is not done and the advisory value is used.
Default:
unset
control_timeout controltimeout
Number of seconds to wait for protocol messages before timing out. This value should be significantly larger than what typical users specify for the -I flag of bwctl or bwctl will have to open a new control connection for each new test it requests.
Default:
7200 (Picked to be the same as the default for TCP keepalive)
die_by dieby
Number of seconds to wait for child processes to gracefully terminate before killing them with SIGKILL. This is in response to the master process receiving SIGTERM or SIGHUP.
Default:
30
facility facility
Syslog facility to log messages.
Default:
LOG_DAEMON
group group
Specifies the gid the bwctld process should run as. group can be specified using a valid group name on the system or by using -gid. This option is only used if bwctld is started as root.
Default:
unset
iperf_cmd iperfcmd
The path to the Iperf command on the system. If the iperf_cmd does not contain a '/' character, then the PATH of the bwctld environment will be searched to find the Iperf executable.
Default:
iperf
iperf_port iperfport
The port number(s) that Iperf receivers will use. Currently, bwctld simply cycles through this range linearly. iperf_port can be specified as a single valid port number or as a range as low-high. The range must be specified as two valid port numbers with the '-' character separating them. Whitespace is not allowed within the iperf_port. For example, "5001-5004" would be valid, but "5001 - 5004" would be invalid.

This value should be set to a range because it can take a few minutes for a port to become free after a test has run. If the port is not free when the next test starts, the test will fail. If set to a range, the daemon will cycle through them when starting tests, decreasing the chance that a port will still be open when the test starts. For best results, ensure that this range is different from that of nuttcp_port and thrulay_port.

Default:
5001
log_location
Directs the bwctld process to report source code file and line number information with error messages. This is a particularly useful option to set when sending in messages as part of a bug report.
Default:
unset
nuttcp_cmd nuttcpcmd
The path to the Nuttcp command on the system. If the nuttcp_cmd does not contain a '/' character, then the PATH of the bwctl environment will be searched to find the Nuttcp executable.
Default:
nuttcp
nuttcp_port nuttcpport
The port number(s) that Nuttcp receivers will use. Currently, bwctld simply cycles through this range linearly. nuttcp_port can be specified as a single valid port number or as a range as low-high. The range must be specified as two valid port numbers with the '-' character separating them. Whitespace is not allowed within the nuttcp_port. For example, "5001-5004" would be valid, but "5001 - 5004" would be invalid.

This value should be set to a range because it can take a few minutes for a port to become free after a test has run. If the port is not free when the next test starts, the test will fail. If set to a range, the daemon will cycle through them when starting tests, decreasing the chance that a port will still be open when the test starts. For best results, ensure that this range is different from that of iperf_port and thrulay_port.

Default:
5001
peer_port 0 | lowport-highport
Specify the port range that will be used on the local host for peer connections to other bwctld servers. These connections are used to verify clock timing between the servers and to exchange test results. This is a required part of the protocol used by BWCTL to run tests. However, this option allows system administrators to limit these connections to a specific port range, which should allow BWCTL to work in a firewall environment. This option can be specified in two ways. First, as a 0, which would indicate that bwctld should allow the system to pick the port (ephemeral). Second, as a range. lowport must be a smaller value than highport and both numbers must be valid port values. (16-bit unsigned integer values)
Default:
0
post_hook /path/to/script
Specifies a script to run after each bwctl session has finished. These hooks can be used to save the results into a database, track usage or any number of other tasks. You can specify as many hooks as you want by including multiple post_hook entries.
priority priority
Syslog priority to log error messages.
Default:
LOG_ERR
root_folly
Disables the checks that disable bwctld if it is run with root permissions. There are legitimate reasons to run bwctld as root, but it is risky. Forcing this additional option will make it less likely root permissions are accidently used.
Default:
unset
src_node nodename:port
Specify the address and port on which bwctld will listen for requests. nodename can be specified using a DNS name or using the textual representation of the address. It is possible to set the source address without setting the port by simply leaving off the ':' and port specification. If an IPv6 address is specified, note that the accepted format contains nodename in square brackets as: [fe80::fe9f:62d8]. This ensures the port number is distinct from the address specification.
Default:
nodename is wildcarded as any currently available address
port is 4823
sync_fuzz syncfuzz
This value is added to the NTP error estimates to increase the tolerance of bwctld to incomplete NTP configurations, or if the NTP system calls are not available. If NTP is unavailable to bwctld it assumes the clock is accurate to within one second plus the value of sync_fuzz. This option is specified as a floating point number in seconds. For example, to indicate that the system is synchronized within one second, you could specify this option as 1.0.

Practically, this option is used to determine the size of the time window buffer before and after each throughput test.

Default:
0.0
thrulay_port thrulayport
The port number(s) that Thrulay receivers will use. Currently, bwctld simply cycles through this range linearly. thrulay_port can be specified as a single valid port number or as a range as low-high. The range must be specified as two valid port numbers with the '-' character separating them. Whitespace is not allowed within the thrulay_port. For example, "5001-5004" would be valid, but "5001 - 5004" would be invalid.

This value should be set to a range because it can take a few minutes for a port to become free after a test has run. If the port is not free when the next test starts, the test will fail. If set to a range, the daemon will cycle through them when starting tests, decreasing the chance that a port will still be open when the test starts. For best results, ensure that this range is different from that of iperf_port and nuttcp_port.

Default:
5003
user user
Specifies the uid the bwctld process should run as. user can be specified using a valid user name on the system or by using -uid. This option is only used if bwctld is started as root. If the given user has root permissions, the root_folly option must also be specified.
Default:
unset
var_dir vardir
Directory path where the bwctld.pid file will be placed.
Default:
Current directory

BWCTL TCP/UDP Port Usage and Firewall Configuration

BWCTL uses three different sets of ports:

  1. Main daemon listening port for control connection (Default: TCP/4823)

    2. Defined using the port portion of the src_node configuration option from bwctld.conf

    For example, to enable this on a typical Red Hat Enterprise Linux system, you would need to add the following line to /etc/sysconfig/iptables:

    -A RH-Firewall-1-INPUT -m state --state NEW -m tcp -p tcp --dport 4823 -j ACCEPT

    This should be added somewhere after the line that allows ESTABLISHED and RELATED connections through.

    This does not use the system-config-securitylevel script from Redhat. I have not been able to get that to do all the things I needed.

  2. bwctld peer connections (Default: TCP/ephemeral range)

    3. Defined using the peer_port configuration option from bwctld.conf

    If you specified peer_port as 9910-9950, you would then need to enable this range in your firewall configuration. (If you do not specify a range, BWCTL will only work reliably if you have open access for the entire ephemeral port range.)

    On a typical Red Hat Enterprise Linux system, you would need to add the following line to /etc/sysconfig/iptables given this range:

    -A RH-Firewall-1-INPUT -m state --state NEW -m tcp -p tcp --dport 9910:9950 -j ACCEPT

    This should be added somewhere after the line that allows ESTABLISHED and RELATED connections through.

    This does not use the system-config-securitylevel script from Redhat. I have not been able to get that to do all the things I needed.

  3. Test Connections (Default: Tool Specific)

    4. Each throughput tester can have its own port defined in bwctld.conf. The configuration option for each tester takes the form testername_port. For example, to set the Thrulay port, you would use the option thrulay_port. The following example would apply to any of the testers, just changing the appropriate configuration option.

    If you specified iperf_port as 5001-5004, you would then need to enable this range in your firewall configuration. If you allow UDP tests (in your bwctld.limits file), you will need to open up the UDP ports. Likewise for TCP. The default is 5001 for TCP and UDP tests, and you will only be able to test if you open the ports specified.

    On a typical Red Hat Enterprise Linux system, you would need to add the following lines to /etc/sysconfig/iptables given this range:

    -A RH-Firewall-1-INPUT -m state --state NEW -m tcp -p tcp --dport 5001:5004 -j ACCEPT
-A RH-Firewall-1-INPUT -m udp -p ucp --dport 5001:5004 -j ACCEPT

    This should be added somewhere after the line that allows ESTABLISHED and RELATED connections through.

    This does not use the system-config-securitylevel script from Redhat. I have not been able to get that to do all the things I needed.

NAME

pfstore - Used to create and manage a pass-phrase store.  

SYNOPSIS

pfstore [-n] [-d] -f pfsfile identity  

OPTIONS

-n
Create the file
-d
Delete given identity from the store
-f pfsfile
Specifies file that holds identity/pass-phrase pairs
 

DESCRIPTION

pfstore is used to create and manage files that hold identity/pass-phrase pairs. It is primarily used to manage the owampd.pfs file for owampd.

If the -d option is not specified, then pfstore prompts the caller for a pass-phrase. The pass-phrase is hex-encoded and saved in the pfsfile with the associated identity. If the given identity already exists in the pfsfile, the previous pass-phrase is overwritten with the new one.

pfsfiles generated by pfstore are formatted for use with OWAMP.  

PFSFILE FORMAT

pfstore generates lines of the format:

test   54b0c58c7ce9f2a8b551351102ee0938

An identity, followed by whitespace, followed by a variable-length hex-encoded pass-phrase.

No other text is allowed on these lines; however, comment lines may be added. Comment lines are any line where the first non-white space character is '#'.  

EXAMPLES

pfstore -f /usr/local/etc/owampd.pfs testuser
Adds a pass-phrase for the identity testuser. The user is prompted for a pass-phrase. If the file does not exist, an error message will be printed and no action will be taken.

pfstore -f /usr/local/etc/owampd.pfs -n testuser

Creates the file before doing the same as above. If the file already exists, an error message will be printed and no action will be taken.

pfstore -f /usr/local/etc/owampd.pfs -d testuser

Deletes the identity testuser from the pfsfile. If the file does not exist, an error message will be printed and no action will be taken.

 

SECURITY CONSIDERATIONS

The pass-phrases in the pfsfile are not encrypted in any way; they are simply hex-encoded. The security of these pass-phrases is completely dependent upon the security of the filesystem and the discretion of the system administrator.  

RESTRICTIONS

identity names are restricted to 80 characters.

NAME

aespasswd - Used to create and manage an AES keyfile.  

SYNOPSIS

aespasswd [-n] [-d] -f keyfile identity  

OPTIONS

-n
Create the keyfile
-d
Delete given identity from keyfile
-f keyfile
Specifies file that holds identity/key pairs
 

DESCRIPTION

aespasswd is used to create and manage files that hold identity/key pairs. It is primarily used to manage the bwctld.keys file for bwctld and the owampd.keys file for owampd.

If the -d option is not specified, then aespasswd prompts the caller for a passphrase. The passphrase is hashed using an internal MD5 algorithm to generate a key that is then saved in the keyfile associated with the given identity. If the given identity already exists in the keyfile, the previous key is overwritten with the new one.

keyfiles generated by aespasswd are formatted for use with BWCTL and OWAMP.  

KEYFILE FORMAT

aespasswd generates lines of the format:

test   54b0c58c7ce9f2a8b551351102ee0938

An identity, followed by whitespace, followed by a hex encoded 128-bit number, that is suitable to be used as a symmetric AES key.

No other text is allowed on these lines; however, comment lines may be added. Comment lines are any line where the first non-white space character is '#'.  

EXAMPLES

aespasswd -f /usr/local/etc/bwctld.keys testuser
Adds a key for the identity testuser. The user is prompted for a passphrase. If the file does not exist, an error message will be printed and no action will be taken.

aespasswd -f /usr/local/etc/bwctld.keys -n testuser

Creates the file before doing the same as above. If the file already exists, an error message will be printed and no action will be taken.

aespasswd -f /usr/local/etc/bwctld.keys -d testuser

Deletes the identity testuser from the keyfile. If the file does not exist, an error message will be printed and no action will be taken.

 

SECURITY CONSIDERATIONS

The keys in the keyfile are not encrypted in any way. The security of these keys is completely dependent upon the security of the system and the discretion of the system administrator.  

RESTRICTIONS

identity names are restricted to 16 characters, and passphrases are limited to 1024 characters.

Definition of HMAC * * The definition of HMAC requires a cryptographic hash function, which * we denote by H, and a secret key K. We assume H to be a cryptographic * hash function where data is hashed by iterating a basic compression * function on blocks of data. We denote by B the byte-length of such * blocks (B=64 for all the above mentioned examples of hash functions), * and by L the byte-length of hash outputs (L=16 for MD5, L=20 for * SHA-1). The authentication key K can be of any length up to B, the * block length of the hash function. Applications that use keys longer * than B bytes will first hash the key using H and then use the * resultant L byte string as the actual key to HMAC. In any case the * minimal recommended length for K is L bytes (as the hash output * length). See section 3 for more information on keys. * * We define two fixed and different strings ipad and opad as follows * (the 'i' and 'o' are mnemonics for inner and outer): * * ipad = the byte 0x36 repeated B times * opad = the byte 0x5C repeated B times. * * To compute HMAC over the data `text' we perform * * H(K XOR opad, H(K XOR ipad, text)) * * Namely, * * (1) append zeros to the end of K to create a B byte string * (e.g., if K is of length 20 bytes and B=64, then K will be * appended with 44 zero bytes 0x00) * (2) XOR (bitwise exclusive-OR) the B byte string computed in step * (1) with ipad * (3) append the stream of data 'text' to the B byte string resulting * from step (2) * (4) apply H to the stream generated in step (3) * (5) XOR (bitwise exclusive-OR) the B byte string computed in * step (1) with opad * (6) append the H result from step (4) to the B byte string * resulting from step (5) * (7) apply H to the stream generated in step (6) and output * the result * * * Licensed under the Apache License, Version 2.0 (the "License"); * you may not use this file except in compliance with the License. * You may obtain a copy of the License at * * http://www.apache.org/licenses/LICENSE-2.0 * * Unless required by applicable law or agreed to in writing, software * distributed under the License is distributed on an "AS IS" BASIS, * WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied. * See the License for the specific language governing permissions and * limitations under the License. * */ #include #include #include #include #include /* * The opad is computed using the key during init.

The length of the derived key is essentially * unbounded. (However, the maximum effective search space for the * derived key may be limited by the structure of the underlying * pseudorandom function. See Appendix B.1 for further discussion.) * PBKDF2 is recommended for new applications. * * PBKDF2 (P, S, c, dkLen) * * Options: PRF underlying pseudorandom function (hLen * denotes the length in octets of the * pseudorandom function output) * * Input: P password, an octet string * S salt, an octet string * c iteration count, a positive integer * dkLen intended length in octets of the derived * key, a positive integer, at most * (2^32 - 1) * hLen * * Output: DK derived key, a dkLen-octet string * * Steps: * * 1. If dkLen > (2^32 - 1) * hLen, output "derived key too long" and * stop. * * 2. Let l be the number of hLen-octet blocks in the derived key, * rounding up, and let r be the number of octets in the last * block: * * l = CEIL (dkLen / hLen) , * r = dkLen - (l - 1) * hLen . * * Here, CEIL (x) is the "ceiling" function, i.e. the smallest * integer greater than, or equal to, x. * * 3. For each block of the derived key apply the function F defined * below to the password P, the salt S, the iteration count c, and * the block index to compute the block: * * T_1 = F (P, S, c, 1) , * T_2 = F (P, S, c, 2) , * ... * T_l = F (P, S, c, l) , * * where the function F is defined as the exclusive-or sum of the * first c iterates of the underlying pseudorandom function PRF * applied to the password P and the concatenation of the salt S * and the block index i: * * * F (P, S, c, i) = U_1 \xor U_2 \xor ... \xor U_c * * where * * U_1 = PRF (P, S || INT (i)) , * U_2 = PRF (P, U_1) , * ... * U_c = PRF (P, U_{c-1}) . * * Here, INT (i) is a four-octet encoding of the integer i, most * significant octet first. * * 4. Concatenate the blocks and extract the first dkLen octets to * produce a derived key DK: * * DK = T_1 || T_2 || ... || T_l<0..r-1> * * 5. Output the derived key DK. * * Note. The construction of the function F follows a "belt-and- * suspenders" approach. The iterates U_i are computed recursively to * remove a degree of parallelism from an opponent; they are exclusive- * ored together to reduce concerns about the recursion degenerating * into a small set of values. * */ #include #include #include /* * Function: F * * Description: * Used in step 3 to compute each block of derived key. * * In Args: * * Out Args: * * Scope: * Returns: * Side Effect: */ static void F( I2prf prf, uint32_t prf_hlen, const uint8_t *pw, uint32_t pwlen, const uint8_t *salt, uint32_t saltlen, uint32_t count, uint32_t i, uint8_t *buffer, uint8_t *u ) { uint8_t ival[4]; uint32_t j,k; /* * U_1 = PRF(P, concat(S, INT(i))) */ ival[0] = (i >> 24) & 0xff; ival[1] = (i >> 16) & 0xff; ival[2] = (i >> 8) & 0xff; ival[3] = i & 0xff; /* * Input of U_1 prf is concat(S, INT(i)), Output hmac put in buffer */ memcpy(buffer,salt,saltlen); memcpy(buffer+saltlen,ival,4); (*prf)(pw,pwlen,buffer,saltlen+4,buffer); /* * Initialize return u with U_1 */ memcpy(u,buffer,prf_hlen); /* * U_2..U_{count} */ for(j=2; j<=count; j++){ /* * Input of U_{j} prf is U_{j-1} or buffer, * Output is put back in buffer for the next time around and is * immediately used to xor into the F result. */ (*prf)(pw,pwlen,buffer,prf_hlen,buffer); for(k=0; k 0xffffffff){ rc = EINVAL; goto end; } #endif /* * Allocate needed memory for complete algorithm at this level to * catch errors early. */ if( !(tmpbuff = calloc(MAX(saltlen,prf_hlen)+4,sizeof(uint8_t))) || !(outbuff = calloc(prf_hlen,sizeof(uint8_t)))){ rc = ENOMEM; goto end; } /* * Step 2 * Let l = number of complete blocks * Let r = number of bytes in any final incomplete block */ l = dklen / prf_hlen; r = dklen % prf_hlen; /* * Step 3 and 4 * 3) iterate over all complete blocks to compute complete prf_hlen blocks * 4) increment 'out' to concatenate each resulting T_{i}. * * (Passing pointer directly into dk_ret, to minimize copies.) */ for(i=0; i * * This software was written by Alexander Peslyak in 2001.

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.

Modified the OWPErr functions to exclusively use the I2Err functions. (The OWPErr functions are simply a wrapper around the I2Err functions - unfortunately they can't be macros due to the var-args...) This means if you want to have an application defined error function, you have to define the I2ErrHandler yourself, and assign it to eh in the OWPContext. This actually simplified things quite a bit. I would almost like to go through and remove all the OWPError and OWPErrLine calls and replace them with I2 varients - may do that later, doesn't seem worth it right now.

There was a mistake in the init function - you only used one malloc, and pointed the "buckets" pointer to the memory just past the I2table record. The problem is that there is nothing making sure that the memory just past the I2table record is aligned properly for pointers (the type of the array). There are two ways to fix this - one, add something to the end of the structure to ensure the next memory is aligned, or just malloc the buckets array seperately. (the extra malloc seemed easier, so that is what I did.) Another mistake in the init function was that you called exit. A library function should almost never call exit - let the calling environment handle the errors, just report them. In this case, it is very easy to just return NULL if there is a problem. I simplified the cmp function slightly - there was no reason to check for the MIN of the sizes in the bcmp (which I changed to memcmp) since you already know the sizes are equal or the first part of the || would have caused the value to be returned already. (lazy evaluation) In init - I reordered the primes array check for sizes so you don't have to have the extra 509, and the bogus INT_MAX in the array. Not really necessary, but I had a hard time following the logic each time I looked at it before. hash_close - I made it take an I2table instead of a pointer to an I2table. It wasn't clear to me why you had it the other way... I also removed the if checkes before the free'ing of the pointers. (If those pointers were NULL you would have core dumped from the lines before the if, because those pointers are dereferenced.) I added a hash_delete function so you can remove a key/value pair from the hash. (I added the iterate function earlier - you probably noticed.) I didn't do it, but I think it would be much cleaner to implement your hash printing using the hash_iterate function. Then you could take the hash_print function pointer out of the hash table structure. Also - you could take the I2binding structure out of the header file since it wouldn't be needed. Everything else I did was purely cosmetic - defined types for the function pointers and things along those lines. jeff ------------------------------------------------------------------------ r14 | boote | 2002-06-18 13:57:58 -0400 (Tue, 18 Jun 2002) | 7 lines Added I2hash_iterate function - this is similar to the "print" function, but allows you to specify a different function to call each time you call hash_iterate.

Tolya - when you create new files please put a $Id$ comment header at the beginning of the file. (I don't really care that much if you use the comment script, but I really want the version number in there - it makes it much easier to determin how out-of-date printout's are.) Also - I moved your arithmatic out of I2util and put it into owamp - it is difficult to imagine something more specific to owamp. I2util is for code that is likely to be used for projects completely unrelated to owamp. I'm thinking more and more about rolling all the owpcontrib code right into the owamp directory, but I decided to leave it alone for now. Let me know if you have opionions one way or the other about it. Oh - I also broke up api.c into 3 files: api.c capi.c sapi.c api.c contains functions that are used by capi.c and sapi.c. capi.c is client api functions and sapi.c is server api functions. Now that I've reorganized the code to more easily digestable chunks, I'm going to start taking some of the code from owampd and putting it in sapi.c, and extending it to actually start test sessions. (I probably won't get enough done today to check in again today - in fact, considering what I will be doing, it will probably be a few days before I check-in again.) jeff ------------------------------------------------------------------------ r10 | karp | 2002-05-31 18:27:50 -0400 (Fri, 31 May 2002) | 2 lines Added support for arithmetic functions. ------------------------------------------------------------------------ r9 | boote | 2002-04-30 12:42:59 -0400 (Tue, 30 Apr 2002) | 15 lines owping first real check-in.

I don't see any reason why owamp_read_ip2class, owamp_read_class2limits, and read_passwd_file couldn't call I2hash_init themselves and return the hash_table as the return value of the function. You could still call I2hash_print for debugging purposes - but the code could be much cleaner this way.

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.

It works by contacting a bwctld process on the remote system and on the local system and requests that those daemons perform a specific iperf test between them. The bwctl software uses the "autoconf" tools to prepare a build process. It is distributed with a pre-built "configure" script - so the "autoconf" tools should not be needed. (gnumake may be required... I have not tried using other versions of make.) BWCTL does require a reasonably synchronized clock. (It is scheduling tests and needs to be sure it has the same general concept of when a test should take place as the peer system the test is being done with.) Therefore bwctl requires ntp be installed and used to synchronize the system clock. The simple build procedure would be: % gzip -cd bwctl-$VERS.tar.gz | tar xf - % cd bwctl-$VERS % ./configure --prefix=/inst/root % make % make install then * edit bwctl-$VERS/conf/bwctld.conf * create user id's with aespasswd (installed from bwctl-$VERS/I2util/aespasswd). [This step is only required if you want to use encrypted or authenticated mode. Policy restrictions are based on identity if possible, and net-masks otherwise so it is possible to run the bwctld without these identities only using net-masks for policy determination.] % aespasswd -n -f bwctl-$VERS/conf/bwctld.keys ${userid} You will be prompted for a passphrase. This passphrase will uniquely identify an AES key. That AES key needs to be installed in the bwctld.keys file for all bwctld servers you wish to contact. (You can add as many userid's to the file as you want. The -n flag is used to create the file initially, so do not use it for subsequent identity additions.) * edit bwctl-$VERS/conf/bwctld.limits You can use either identities from the bwctld.keys file or setup net-masks within this file to define "classes" of users. This file is used to assign "limits" to those "classes" of users. * copy bwctld.{conf,limits,keys} to the config directory. (/inst/root/etc?) There is currently no build process to help build the bwctld configuration file - or to build "init.d/rc" scripts. There are the start of some of these things in the $bwctl/scripts and $bwctl/conf directories. To run the daemon: % bwctld -c /path/to/confdir (/inst/root/etc in above) The daemon will run without a bwctld configuration file if you use enough of the command-line flags - but it is much easier to use the config file. There is an example configuration file in $bwctld/conf/bwctld.conf. To get the list of available options use: % bwctld -h [bwctld -h will give you the list of options. Specifically, if you have problems you may want to use the -Z flag to run it in the foreground and have error messages come to the console in addition to syslog.] To run the client: % bwctl [options] [-c catchhost] [-s sendhost] At least a -c or a -s must be specified to indicate the direction of the test. If only one of them is specified, the local host is assumed to be the other one. If a local bwctld is not running, then bwctl will execute the bwctld functionality required to run the test. To get the list of available options use: % bwctl -h [I tried to keep as many of the iperf command line options as I could...] Problems/Questions can be reported to bwctl-users@internet2.edu. Mailing Lists: I have created two email lists to support this software: bwctl-users A general discussion list for users to discuss problems. I will monitor this list as I expect bug reports to be sent here. bwctl-announce This list will be used to announce new versions or significant developments with regard to the software. These lists can be subscribed to from: https://mail.internet2.edu/wws/lists/engineering Jeff Boote Internet2 bwctl-1.4.1/bwlib/0000775000076700007720000000000012040244644010744 500000000000000bwctl-1.4.1/bwlib/error.c0000664000076700007720000000332212015235430012154 00000000000000/* ** $Id: error.c 566 2012-05-03 14:23:48Z aaron $ */ /************************************************************************ * * * Copyright (C) 2003 * * Internet2 * * All Rights Reserved * * * ************************************************************************/ /* ** File: error.c ** ** Author: Jeff W.

Boote * Internet2 * * Date: Fri Aug 31 13:48:52 MDT 2007 * * Description: * * This file is used to define the current set of understood/known * tester tools for bwctl. Currently there is no way for individuals to * add tools since the existance of a particular test program is * communicated by a bit-field. (It needs to be unique across all * clients/servers.) In the future, the protocol could be * changed to something more extensible (XML messages) at which point * it could be possible to communicate all kinds of extra information * if wanted. (Hey, throughput and memory are cheap these days - might as * well use them. But, this is work for another day.) Each tool would * still need to have a unique identifiable signature, but perhaps the * names 'iperf', 'nuttcp' would be enough... Probably need to include * a version indication as well. * * Currently, this is just setup to use the autoconf to compile in specific * tool 'drivers' or not. Additionally, when bwctl[d] is started it * will look to determine which testers are actually available in * the environment to cull-out this list. * * Much of the functionality to run multiple tools was initially * developed by Federico Montesino Pauzols as part of a thrulay Google * Summer of Code project mentored by Jeff W. Boote. That effort put * this functionality in-line within the existant structure. This * file is an effort to refactor that functionality into a more modular, * and hopefully extensible configuration. * * License: * * Licensed under the Apache License, Version 2.0 (the "License"); * you may not use this file except in compliance with the License. * You may obtain a copy of the License at * * http://www.apache.org/licenses/LICENSE-2.0 * * Unless required by applicable law or agreed to in writing, software * distributed under the License is distributed on an "AS IS" BASIS, * WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied. * See the License for the specific language governing permissions and * limitations under the License. * */ #include #include static BWLToolDefinitionRec BWLToolNone = { "", NULL, NULL, 0, NULL, NULL, NULL, NULL, NULL }; /* autoconf seletion of tools here... */ #ifdef TOOL_IPERF extern BWLToolDefinitionRec BWLToolIperf; #else #define BWLToolIperf BWLToolNone #endif #ifdef TOOL_IPERF3 extern BWLToolDefinitionRec BWLToolIperf3; #else #define BWLToolIperf3 BWLToolNone #endif #ifdef TOOL_NUTTCP extern BWLToolDefinitionRec BWLToolNuttcp; #else #define BWLToolNuttcp BWLToolNone #endif #ifdef TOOL_THRULAY extern BWLToolDefinitionRec BWLToolThrulay; #else #define BWLToolThrulay BWLToolNone #endif BWLToolRec tool_list[] = { {BWL_TOOL_IPERF, &BWLToolIperf}, {BWL_TOOL_IPERF3, &BWLToolIperf3}, {BWL_TOOL_NUTTCP, &BWLToolNuttcp}, {BWL_TOOL_THRULAY, &BWLToolThrulay}, {BWL_TOOL_UNDEFINED, &BWLToolNone} }; BWLBoolean _BWLToolInitialize( BWLContext ctx ) { uint32_t i,m,n; /* * If there is a reasonable way to 'register' the bit signature for * a tool...

Legal conditions are in file LICENSE (MD5 = ecfa50d1b0bfbb81b658c810d0476a52). Motivation Popular network capacity testing and traffic injection packages (such as netperf, iperf, nettest, nuttcp, ttcp, etc.) do not measure round-trip time in any way. This program, thrulay, does. Having delay information along with goodput information clarifies what is happening for Reno; but for delay-based TCP variants (such as FAST TCP), it's even more important. The output of thrulay is easier to parse by machine than that of iperf. In fact, it's ready to be used as a data file for gnuplot. Be aware that the code is intended to be run over high-speed networks. It won't work nearly as well over, say, a modem, for two reasons: (i) delay includes the serialization delay of one data block (negligible for high-speed networks, dominating for modems); (ii) more than a single reporting interval may be spanned by a single report line because thrulay requires at least one block to be delivered per reporting interval to work as designed. Installation To build the programs, type the following commands: $ ./configure $ make To install the program on your system, type the following command as root: # make install NOTE: If you use a BSD variant other than Mac OS X, you will need to use `gmake' (GNU make) instead of `make' (BSD make). Running On the server: thrulayd # Messages go to syslog. On the client: thrulay server # Output goes to stdout, errors -- to stderr. The thrulayd server should be added to system startup scripts. The exact preferred location varies from system to system, but /etc/rc.local is one file that is almost universally honored.

This option can be used multiple times. The argument is either an IP address or an address in CIDR syntax (if you leave the netmask, it will be set to 32 for IPv4 or to 128 for IPv6 addresses). Examples for valid addresses: 192.168.1.3, ::ffff:192.168.1.3, 192.168.1.3/24, ::ffff:192.168.1.3/120. If the server is started without this option, all hosts are allowed to connect by default. If this option is used, only the specified addresses are allowed to connect. .IP "-w#" Window, in bytes (default: 4194304B). .IP "-p#" Server port (default: 5003). .IP "-d" Debug mode. The program does not fork into background and all logging messages go to stderr. .IP "-j group" Join a multicast group. If this option is given multiple times, only the last group is considered. .SH BUGS Please send bug reports to thrulay-users@internet2.edu. .SH AUTHOR Stanislav Shalunov, http://www.internet2.edu/~shalunov/ .SH "SEE ALSO" .BR thrulay(1) bwctl-1.4.1/thrulay/doc/thrulay-logo.png0000664000076700007720000000547212015235431015162 00000000000000‰PNG  IHDRâ¿@)èbKGDÿÿÿ ½§“ pHYs``zxEtIMEÕ (>“±u ÇIDATxÚíÝm¯gð93¼õ…‰ý$†Ä7F‰VÕ¨Dû ­ ò¬D*iCŽ%”R–œŠAàQÚSh)bj°-AÒƘ4~?Äú†¥°ôìÎÃ=÷Ü3óû%›PÊîÎÎÜóŸëÚ¹ggi2™L2€ r«€à 8Á 8Á@p‚@p‚€à€àêÛÔäÉ_Üv²·ü_oþÜÖ'¸-=Þ'nWØ'T@ÜŠ˜9çã87 Ž"W°À(Ò*´*С¢ÐªhU­  UôZgUÊôsKF hU´*¹UGÞ(8rgU@« UØGbÀÊôs ЪhU .Àʬ¤BÁZ­ ÄnUL³’­  UôŽÄ&€•XI&€V@«‘™Vf%™Z­ hUlUœU­ €Vb·*…kU—+î«Ò[lÞÿÐßýï£ßÖ~~•ç¢â ‡û}„Šà@hÔZŽ±„Gî¬J‰~ÎYJPq 0 ­;,hUFÐrtm¶@}ÿÒÕ0+i°;g׃êIÅÀ¨üÙˆà a`Œé,żõ”â:(ü˜•4D!v¶y¯ab˜ŠAíý|§#8ˆT²ùhžêgÏÝWÅJŠ½#8ê¢â`tGÛŸ©LxúÞDp º•¨:ÈçUcÙYîÿœ¡*°˜m `VRãÐ1h}Ñ,@¦Ï5DÅÑ‹ÀíH“ß ‰]}„põÿdO<ö9Á1ÆÀû6Ú˜Ømdé*<àܦ·þúï௙F«b˜3!=Þ.½>{~ƒYuš8ýߎ±L« ÁðHx=‡Ú6Ežy̆H¨×-ûží¶*#>«bÂÖð¶g*.ÝøP«ÂÇS?=¾ðµ¨œvP‡Ü>y¾Ôè±QµqéƇ_{Ñ#Z«âZ³=ûÞRÚFõŸÇ±~ýƒ,˲lûÖÏ«DHj{¤þ[!Ó}g”­Ê40Ö¯Ы*(„Ƹ½(òÚ2ÁÒäõ›¾°Š£ì‡Í²,Ûù½/ôbpÕU(0†mN»xíN¯Öc´/G/^»“üÊ™½8 fǃqÑbpÌ«.R .ˆ‚Ùq0o¶i‰WUö‡‹×îŒ{Øteí~bKreÆǘ¯ué|ÇÚÕÛÙÚÕÛɆ†`¡ÍñÑÕØO68ªV±Äj„Úî÷ÿ»<Ï+=ê†MÕ÷ ½,‚£­•ÒÖŠ™>ê”ð¡ÇÇ…+·´*¡]¸r«•[ç5]g2>u¶÷˜.É_«:@ö>õ¥Öã ¢X*õh:¦/\¹Uú½Ê>¢Ç¢9ðô—ƒHˆTv¹„U¥^Å‘¨ÕËïg«—ßo}@ ªŒ…*ã%ÄøÈFPeLÜÿÿBO´Z´t5¬Y«Rbaþà+Q¤îJšBƒ*áQu¼œ{ãÝA¬‹ÁÜaºAê•° ÊXqs§ÞW¥I€@Óͼ’ÿìë7ƒ/KW¿ûÛð¬J¹ëüýðkȹ7Þ òÛª6¨õàèÅŠ}ífvöµ›F£ÜÁµ*$˲NªÆ#ÿ„jöÕ?ü#ú{&]qT¹>äg?úº „Ñi;4b½Çh+ŽY¾gh;³à ôx,u¡ˆ|«’¥Éd2©ûäW~÷÷ÊÏ9³öNÒ_€Ð—°˜õÜîÇ=ÿù=ßPq¨@CXhU¢a»ïìJ£Ve¥æ@§Ïÿ­wG€‹>8²÷›µŸ{xWù3Ÿ*Z­ŠaÌak2X£V¥ÉDª“«Ć Â"5˾UëyÏV˜U­âP ªW6VA¸ipª Sü/€Åºù‹!TxŒ!@NüúÏí8Žþä;*HOùŽ#Rom ¦Û¾ 1à«Þ'%jÅó0C T CÐètìo.¿×x^üÕõÁÑò]xñ§[+ýû?ý¨VEXÐd!<Ú¼veSª &,Ha›j1[hUοæfÐGù'aö¥'žýné»ïûåoÈ®U ¸ikΔVEX …‰Ûª¬½};Ø‚,¯üQP …iÁÉ×úw{žÜ¢U¨@îv-\jß(8òßJQX …i°ï§² §Ÿ2ÚûÄz/Æ'Åñuä•·Óª8ú¸Q¡Õ¶àîýMÎy*˲,{îô•¤–+‰àˆ}˜&¦ºw©ÈàZ;7C.ÇwèàÚ4–QŽÄ æ6­,o˲,ËŸz3¹e‹Øªôã¬JÕåô´­Ë\«Ò†Wïn ª¡1ûg˜7fꎕ•åm÷B¤m!C*ïûŽz”ù;Ø(0Š"¯õ8{ô™ììÑgÚ¯¾ç,C´V%õ `¡6Ä#›÷k[ˆr@™ŽÙC'.iU†0TÄ ±*AGˆVå5ÊáÁ¢1P÷ž&=ÎÛž;¶=Øò:q)È}U{V¥ì²U g\„F¦áqðøºŠ£í•\† OÕfè dpÁsåÂUºKQ«Çwd«ÇwÔZƃÇ×?ñ5£GÓûª´qß•Õ—vÔzí*á!hÆ'ÕmÞ$@´*Ç¢"4„‡I<8V_ÚÑ꿯:@„‹Æ@^ä>ο¼3;ÿòÎ…ŸãÀ±×znƒ:«ryfoÊ#4èS52 }/\ÔªÌs¡DÊÖ BƒB"õûΖ­@ªjô+ç×ÿùQ”¿·DjV Ž­_ÝÜê2›ïÑ¡·Ó÷þ›ôçݽüûþ{íÔ®{þö£ŸSqäyå±ÈÚ©]Á_3Ä`œý3i†Æ˜¶ÓÚ©]„E]nÐâ`T}ôo;e5 ¼ï2Dz¶9«üâl£6·CèkUb>¢UE—Õ=»·‹ê#ÍPcÕ1øŠc#±§w3Ö‘fÛßq$70§Ùx$.–Æñ9ûÒÏ­ŸÙ÷À{¯ŸÙ­Ÿ0 V%%U' ›¸ÛÆ@«òPõ‘Ú ]Ôº˜Ã˜ªpÇ•´õqye°÷M©ú ÛP°½FPqLãOƒµÉÅr³Õ‹ž½øÐúQ«ÒÇ£]3/f¡.^u·C[ëo,­Ê ï«2´þ¹­£nŸÃ¢ê„-†ŠÃÑu Uˆ X‚ƒžV4} šT>QhUôst‚ª •ê±ÏÒÄz?§ GÜŠGÜ&;̼÷)ûºªƒåù8®UѪ$cÞ)ˆ§*CÅAË2¤‚ƒŠ;JŸçpTù.¢·¨0¬L?7’ßp´õY™Ù÷­@«]¶*&€éç´C âs ôÁ#8Pa‰’LÓª¤UhU C&€•YI~ ´*ZˆÝª˜V¢\É]«Z­ DnUœUÑÏZ@« ‰]«¢Ÿ´*€VÒc˜VЪZH±U1¬D¹â¾* UЪ@ì#±³*ú9@«hU =…kU´*€VЪ@Š­Š³*‹Ë¿Z­ ÄnUL+ÓϹV´*Zˆ|$vV¥L«¢`­ €Vâr­J™•dhU´*»U1¬D¹â¬ ¨8€f>óéOâs.M&“‰Í Tê6¬@p‚€à€à 8ÁÁ@p‚÷ü4ñÕ*! ätIEND®B`‚bwctl-1.4.1/thrulay/doc/RELEASE-0.70000664000076700007720000001623312015235431013330 00000000000000-----BEGIN PGP SIGNED MESSAGE----- thrulay-0.7 release notes This release incorporates the results of the work of Bernhard Lutzmann on his Google Summer of Code project. Bernhard's project report is appended to these release notes. I would like to thank Bernhard for his hard work on thrulay this summer and to congratulate him on the excellent results. We are in the process of incorporating of changes made by Huadong Liu in his Google Summer of Code project into the main code base. These should be included in a future release. Most importantly, they would include (i) an API for programmatic access to thrulay tests (this is useful for tools that wrap thrulay in other code for the purposes of regular monitoring, coordination of tests or additional access control) and (ii) improvements to on-the-fly quantile calculations. In addition, Huadong will serve as a release engineer for the project.

INTRODUCTION This is the final report for "thrulay-ng: Enhancements for thrulay", a Google "Summer of Code" [1] project. It summarizes all the accomplishments that have been made during the summer. For additional information about thrulay-ng please visit the project homepage at http://thrulay-ng.sf.net/ 2. ACCOMPLISHMENTS The features are listed in chronological order of implementation. * GNU autotools In the initial phase, the source code of thrulay 0.6 [2] has been adapted and support for GNU autotools has been added. This allows users to easily configure and build the programs from the source code. At this stage, thrulay worked under the FreeBSD and Linux operating system. This source code base has been integrated into the SourceForge.net CVS repository where all future development took place. * multiple TCP streams Next, I decided to implement support to run multiple TCP streams. I started out with using POSIX threads for this. Testing an initial version of the multi-stream code on several operating systems revealed that implementing this with threads was a bad idea. The results were everything else than satisfactory. After discussing this with Stanislav and Jeff, Stanislav wrote a very nice article [3] on the different possibilites on how to implement parallel tasks. Based upon this article and digging in "Stevens, UNIX Network Programming, Vol. 1" I descided to try an event-based approach. Changing from threads to events was not that expensive, but fortunately results looked much better now. * API for programmatic execution of tests While implementing multi-stream support, the client-code has also been rearranged into several functions. This revealed in a basic client API that could be used to run tests. * Report MTU/MSS, set DSCP value for TOS byte After this, code has been integrated to guess the Maximum Transmission Unit (MTU) and Maximum Segment Size (MSS) if a TCP test is started. The client is now also able to set a Differentiated Services Code Point (DSCP) value for the Type of Service (TOS) byte in the IP header. * SPARC/Solaris support The source code has then been ported to SPARC/Solaris. * IPv6 support Some of the network code has also been changed to be less protocol specific and that the client and server also work in an IPv6 environment. * documentation: manual pages To better document the usage of the client and server program, manual pages have been written. * UDP statistics: duplication, reordering The next point was to improve the statistics reported in UDP mode. In a first step, I fixed some little bugs in the current UDP code. Then I added support so the server is able to calculate duplication and reordering [4] of packets. * client authorization After that, the server has been enhanced to be able to perform client authorization based on netmasks. * integration of TSC timekeeping projects At this point of development, the TSC timekeeping projects fasttime [5] and TSC-I2 [6] reached a usable state. So support for these have been added to thrulay-ng. The configure script automatically detects if one of them is installed and uses it as a replacement for the gettimeofday() system call. * UDP statistics: quantiles Then I added another statistic in UDP mode: quantiles. This has been implemented as described in [7] using the "New Algorithm". thrulayd now calculates the 0th (minimum), 50th (median) and 95th quantile. * code review issues In the middle of August, Jeff posted his valuable code review [8]. Fixing the noted issues was the work of the following days. In an IRC session he also mentioned that it would be fine to be able to easily build a release out of the CVS version. Thus I have added a script and the file README.release, which documents how to release a new version of thrulay. * Mac OS X port At the end of the project, thrulay has also been ported to Mac OS X and currently supports Linux, BSD (FreeBSD, OpenBSD, NetBSD), Mac OS X and Solaris. Version 0.6.2 of thrulay-ng has been released at the end of August. This package contains all the changes noted above. You are invited to give it a trial. The source code can be downloaded from [9]. 3. ACKNOWLEDGEMENT First I would like to thank my mentors Jeff W. Boote and Stanislav Shalunov of Internet2 for their great support and guidance. Second I would like to thank all the students from the soc2005 mailing list. Many thanks also to Google for sponsoring this project. The "Summer of Code" was a nice happening. Last but not least I would like to thank my friends Christian Schwind and Bernhard Wachter for books, wine and discussion. 4.

thrulay, network capacity tester

The program thrulay is used to measure the capacity, delay, and other performance metrics of a network by sending a bulk TCP or UDP stream over it.

Special features of thrulay include:

  • For TCP, ability to measure round-trip delay along with throughput
  • For UDP, ability to measure
    • one-way delay, with quantiles
    • packet loss
    • packet duplication
    • reordering
  • For UDP, the ability to send precisely positioned true Poisson streams (microsecond errors in sending times)
  • Human- and machine-readable output (ready to be fed to gnuplot)

To accomplish this, a simple protocol is used. The protocol consists of an interaction between a client and a server. The bulk of the data is always sent by the client; the server merely sends back control messages and small records that help the client measure the round-trip time. The server typically listens on TCP port number 5003. The simple protocol is binary (most characters are actually printable, but newlines are not used as record separators). Literals in double quotes are represented in ASCII (which coincides with their UTF-8 representations). Once a connection is established, the server MUST send the greeting: "thrulay/2" (no quotes are actually sent; the character after the slash designates version number; the only version number currently defined is 2, with 1 being an old deprecated version). Then, the server MUST send a single character, either "+" or "-". If the "-" character is sent, it MUST be followed by a (possibly empty) string of UTF-8 characters that give the reason for rejecting the connection; the connection MUST be closed by the server once the string is sent. If the "+" character is sent, the server then expects to read a response from the client. The response will tell the server the parameters of the session. If the first 10 characters sent by the server are not "thrulay/2+", then the client MUST close the connection. (All matches in thrulay protocol are case-sensitive.) If the first 10 characters sent by the server are "thrulay/2-", then the client MAY display subsequent characters (possibly processed in some way) to the user if there is one or record them somewhere as a reason for session failure. If the first 10 characters sent by the server are "thrulay/2+", then the client MUST send a session proposal. A session proposal is described as follows: ::= "0" | "1" | "2" | "3" | "4" | "5" | "6" | "7" | "8" | "9" ::= | ::= "thrulay" ::= "2" ::= "/" ::= ::= ::= "t:" ":" ::= ::= ::= ::= ::= "u:" ":" ":" ":" ::= | ::= ":" "+" In a TCP proposal, the server is asked to use the requested TCP window size. Requested TCP block size is the requested size of the read blocks; it MUST be at least 16. In a UDP proposal, the client port (an unsigned integer less than 65536) is the port that the client intends to use to send the data from. The packet size is the length, in octets, of UDP test packets; the complete IP packet is accounted for, but link-layer headers and trailers are not included within the packet size. The rate is the average rate, in packets per 1000 seconds, that the client wants to use in the test. Finally, the number of packets to be sent is specified. The server reads the session proposal, always terminated by the "+" character. TCP proposal The server MUST respond to a session proposal that contains a TCP proposal with a TCP session response: ::= ::= ::= ":" "+" Here, window is the actual window size that the server will use. If resources and policies allow, window SHOULD be equal to the requested window. Block size is similar; it MUST be at least 16. Once this exchange is over, the client MUST send zero or more blocks of test data. Upon receipt of each block, server MUST send back the first 16 bytes of the block. The client MAY use the 16-byte `block headers' arbitrarily; one possibility is to measure the round-trip time by embedding timestamps in them. Once the client is finished testing, it MUST close the connection. The server MUST then close the connection as well. UDP proposal In the case when a session proposal that contains a UDP proposal is sent by the client, the server MUST respond with a UDP session response: ::= ::= ::= ":" ":" ":" ":" "+" ::= "u:-" ::= | An octet above is defined as an arbitrary octet, with values from 0 to 255. If a negative UDP session response is received by the client, the test fails and the client MUST close the connection. The server MUST also close the connection after sending a negative UDP session response. If a positive UDP session response is used, the server port is the UDP port number that the server will use to receive the test packets from the client; it has no relationship to the client port. The server port SHOULD be 5003, if that port is unused; if that port is used, it SHOULD be 5004, and so forth. The packet size and the rate specified by the server SHOULD be the same as those specified by the client, if policy considerations and network configuration allow that. Regardless of whether they are the same as those specified by the client, the client MUST use the server-specified values. The nonce is a pseudo-random eight-octet quantity used for security purposes. The UDP test consists of a stream of UDP packets sent from the client (using the client port as the source) to the server (with the server port as the destination port). Each packet has the length specified in UDP session response. The negotiated average rate needs to be approached with the best practical approximation of a Poisson stream; whatever are the deviations from a true Poisson stream, there MUST be no long-term bias. The TCP connection is not closed while the UDP test is going. Both the client and the server MUST refrain from sending any data over the TCP connection (and SHOULD refrain from sending TCP keep-alive probes) while the UDP test is active. When the client is done with the test, it sends a single character over the TCP connection; this character can be "+" to indicate successful end of session and "-" to indicate that the session is aborted (no other values are legal). In the case the "+" character is used, it is followed by a number (decimal) that represents that total number of packets sent, followed by a colon (":"). In both cases ("+" or "-"), the server stops listening to further UDP traffic; in the case when a "+" was sent, the server transmits arbitrary UTF-8 characters that constitute the results of the session. Then, the server closes the TCP connection. The format of test packet payload (the normal IP and UDP headers are, of course, also present) is as follows: 8 octets of nonce are followed by 8 octets of sequence number are followed by 8 octets of timestamp are followed by zero or more octets of padding to bring the packet size to the negotiated value. The value of nonce is the value specified by the server in UDP session response. Sequence number is an unsigned binary integer in network byte order; it starts at 0 and is incremented by 1 with each packet. The timestamp has the same format as the NTP timestamp in RFC 1305. Padding contains arbitrary data. bwctl-1.4.1/thrulay/configure0000775000076700007720000263254312037334605013206 00000000000000#! /bin/sh # Guess values for system-dependent variables and create Makefiles. # Generated by GNU Autoconf 2.63 for thrulay 0.9. # # Report bugs to . # # Copyright (C) 1992, 1993, 1994, 1995, 1996, 1998, 1999, 2000, 2001, # 2002, 2003, 2004, 2005, 2006, 2007, 2008 Free Software Foundation, Inc. # This configure script is free software; the Free Software Foundation # gives unlimited permission to copy, distribute and modify it. ## --------------------- ## ## M4sh Initialization. ## ## --------------------- ## # Be more Bourne compatible DUALCASE=1; export DUALCASE # for MKS sh if test -n "${ZSH_VERSION+set}" && (emulate sh) >/dev/null 2>&1; then emulate sh NULLCMD=: # Pre-4.2 versions of Zsh do word splitting on ${1+"$@"}, which # is contrary to our usage.

Like other tools (such as iperf, netperf, nettest, nuttcp, ttcp, etc.), thrulay can report TCP throughput periodically so that TCP performance plots can be produced. Unlike other tools, thrulay not only reports goodput, but round-trip delay time as well. The output of thrulay is easy to parse by machine (in fact, it's ready to be used as a data file for gnuplot). Starting from version 0.5, thrulay supports UDP tests. Unique feature of thrulay is that it can send a Poisson stream of very precisely positioned packets; the TSC register is used for timing rather than very coarse (20ms on most systems) system sleep functionality. %files %package client Summary: thrulay client Group: Applications/Network Requires: thrulay-libthrulay %description client thrulay command line tool for opening client thrulay connections to a thrulay server. %package server Summary: thrulay server Group: Applications/Network Requires: thrulay-libthrulay %description server thrulayd command line tool. %package libthrulay Summary: thrulay API implementation Group: Development/Libraries %description libthrulay thrulay client and server API implementation. %package devel Requires: thrulay-libthrulay Group: Development/Libraries Summary: thrulay library headers. %description devel This package includes documentation, header files, and static link libraries for building applications that use the thrulay library. %prep %setup -n thrulay-%{PACKAGE_VERSION} ./configure --prefix=%{_prefix} %build uname -a | grep SMP && make -j 2 || make %install make prefix=$RPM_BUILD_ROOT/%{_prefix} \ mandir=$RPM_BUILD_ROOT/%{_mandir} \ infodir=$RPM_BUILD_ROOT/%{_infodir} install %files client %defattr(-,root,root,0755) %doc LICENSE README doc/thrulay-protocol.txt doc/RELEASE-0.7 doc/RELEASE-0.8 %{_prefix}/bin/thrulay %files server %defattr(-,root,root,0755) %doc LICENSE README doc/thrulay-protocol.txt doc/RELEASE-0.7 doc/RELEASE-0.8 %{_prefix}/sbin/thrulayd %files libthrulay %defattr(-,root,root,0755) %{_prefix}/lib/libthrulay.so* %files devel %defattr(-,root,root,0755) #%doc ChangeLog doc/refman/ %{_prefix}/lib/libthrulay*.a %{_prefix}/include/thrulay/client.h %{_prefix}/include/thrulay/server.h %clean %post /sbin/ldconfig -n @libdir@ %postun /sbin/ldconfig -n @libdir@ %changelog * Wed Jul 05 2006 Federico Montesino Pouzols 0.8.0 - Initial version. bwctl-1.4.1/thrulay/aclocal.m40000664000076700007720000077671512037334602013144 00000000000000# generated automatically by aclocal 1.9.6 -*- Autoconf -*- # Copyright (C) 1996, 1997, 1998, 1999, 2000, 2001, 2002, 2003, 2004, # 2005 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. # libtool.m4 - Configure libtool for the host system. -*-Autoconf-*- # serial 48 AC_PROG_LIBTOOL # AC_PROVIDE_IFELSE(MACRO-NAME, IF-PROVIDED, IF-NOT-PROVIDED) # ----------------------------------------------------------- # If this macro is not defined by Autoconf, define it here. m4_ifdef([AC_PROVIDE_IFELSE], [], [m4_define([AC_PROVIDE_IFELSE], [m4_ifdef([AC_PROVIDE_$1], [$2], [$3])])]) # AC_PROG_LIBTOOL # --------------- AC_DEFUN([AC_PROG_LIBTOOL], [AC_REQUIRE([_AC_PROG_LIBTOOL])dnl dnl If AC_PROG_CXX has already been expanded, run AC_LIBTOOL_CXX dnl immediately, otherwise, hook it in at the end of AC_PROG_CXX.

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 following components of LINK-COMMAND are treated specially: -all-static do not do any dynamic linking at all -avoid-version do not add a version suffix if possible -dlopen FILE \`-dlpreopen' FILE if it cannot be dlopened at runtime -dlpreopen FILE link in FILE and add its symbols to lt_preloaded_symbols -export-dynamic allow symbols from OUTPUT-FILE to be resolved with dlsym(3) -export-symbols SYMFILE try to export only the symbols listed in SYMFILE -export-symbols-regex REGEX try to export only the symbols matching REGEX -LLIBDIR search LIBDIR for required installed libraries -lNAME OUTPUT-FILE requires the installed library libNAME -module build a library that can dlopened -no-fast-install disable the fast-install mode -no-install link a not-installable executable -no-undefined declare that a library does not refer to external symbols -o OUTPUT-FILE create OUTPUT-FILE from the specified objects -objectlist FILE Use a list of object files found in FILE to specify objects -precious-files-regex REGEX don't remove output files matching REGEX -release RELEASE specify package release information -rpath LIBDIR the created library will eventually be installed in LIBDIR -R[ ]LIBDIR add LIBDIR to the runtime path of programs and libraries -static do not do any dynamic linking of uninstalled libtool libraries -static-libtool-libs do not do any dynamic linking of libtool libraries -version-info CURRENT[:REVISION[:AGE]] specify library version info [each variable defaults to 0] All other options (arguments beginning with \`-') are ignored. Every other argument is treated as a filename. Files ending in \`.la' are treated as uninstalled libtool libraries, other files are standard or library object files. If the OUTPUT-FILE ends in \`.la', then a libtool library is created, only library objects (\`.lo' files) may be specified, and \`-rpath' is required, except when creating a convenience library. If OUTPUT-FILE ends in \`.a' or \`.lib', then a standard library is created using \`ar' and \`ranlib', or on Windows using \`lib'. If OUTPUT-FILE ends in \`.lo' or \`.${objext}', then a reloadable object file is created, otherwise an executable program is created." ;; uninstall) $echo \ "Usage: $modename [OPTION]... --mode=uninstall RM [RM-OPTION]...

Calls to exit() inside the library have been replaced with return codes. Before daemonizing, calls to error(ERR_FATAL,...) have been replaced with return codes After daemonizing, calls to exit() have been replaced as well with return codes (most of which will not be accessible unless the low level thrulay_server_process_client function is used). Additional checks replacing assert() calls and unchecked error conditions. New function, thrulay_server_strerror, to retrieve descriptions of error return codes. Documentation extended. New function in server.c, tcp_test (equivalent to udp_test). ------------------------------------------------------------------------ r105 | fedemp | 2006-08-19 10:58:09 -0400 (Sat, 19 Aug 2006) | 2 lines Report just the 5 metrics in the draft. ------------------------------------------------------------------------ r104 | fedemp | 2006-08-19 10:54:47 -0400 (Sat, 19 Aug 2006) | 2 lines Check return codes of the client interface. ------------------------------------------------------------------------ r103 | fedemp | 2006-08-19 10:53:14 -0400 (Sat, 19 Aug 2006) | 15 lines Return codes have been added to most of the client API functions. New function for the client API: thrulay_client_strerror. A new array of char*, thrulay_client_error_s, holds the error strings, that can be retrieved using thrulay_client_strerror. As a side effect, some asserts have been removed and additional checks have been introduced. Documentation of the API has been improved a bit. The idea has been replacing error(ERR_FATAL,...) calls with return codes that can be handled by the application using libthrulay, as it does not seem very polite to exit() inside the library without giving any opportunity of retrying or somehow handling the error. See bwlib for an example in which bwctl control error messages are generated. Another example is the thrulay command line tools. ------------------------------------------------------------------------ r102 | fedemp | 2006-08-19 10:52:44 -0400 (Sat, 19 Aug 2006) | 2 lines Report just the 5 metrics from the draft unless verbose output is requested. ------------------------------------------------------------------------ r101 | fedemp | 2006-08-18 19:16:02 -0400 (Fri, 18 Aug 2006) | 5 lines Include sys/select.h only if available (and assume select() is defined somewhere else -sys/time.h for example on some HP-UX).

(htons gives bogus warnings on OS X so I couldn't remove them.) Modified the protocol to support bandwidth limits for UDP of greater than 4.3gbps. I did this by adding an 'exponent' byte into the test request message - if the server supports the later protocol version, then this value indicates the number of bits the existing bandwidth word should be shifted to get the 'real' value requested. (As part of this, added some better error checking to see if limits that are larger than can be handled will be detected and reported as an error instead of being munged by overflow. Fixed what must have been a long-standing bug in the policy code. Due to a mistake, child limit definitions have been able to specify larger limits for things like bandwidth than the parent specified. This bug has now been fixed - if a parent limit is more restrictive it will be used in place of less restrictive limits specified in child limit definitions. ------------------------------------------------------------------------ r459 | boote | 2008-06-05 18:38:11 -0400 (Thu, 05 Jun 2008) | 3 lines Make successful request log as well as unsuccessful ones. ------------------------------------------------------------------------ r458 | boote | 2008-06-05 17:47:36 -0400 (Thu, 05 Jun 2008) | 3 lines Fix typo in limits exceeded message. ------------------------------------------------------------------------ r457 | boote | 2008-05-27 18:10:40 -0400 (Tue, 27 May 2008) | 4 lines Track NTP sync state changes and print out sync/unsync messages when state changes. ------------------------------------------------------------------------ r456 | boote | 2008-05-27 15:55:46 -0400 (Tue, 27 May 2008) | 3 lines Fix to make allow_unsync actually work on systems that have ntp syscalls. ------------------------------------------------------------------------ r455 | aaron | 2008-05-27 13:19:15 -0400 (Tue, 27 May 2008) | 3 lines configure should now accept --disable-nuttcp/--disable-iperf instead of requiring --disable-NUTTCP ------------------------------------------------------------------------ r454 | aaron | 2008-05-23 18:01:01 -0400 (Fri, 23 May 2008) | 4 lines Disable Nuttcp UDP tests since they're currently not working Improve the error messages for when iperf or nuttcp aren't found to allay fears that something catastrophic happened. ------------------------------------------------------------------------ r453 | aaron | 2008-05-23 16:48:50 -0400 (Fri, 23 May 2008) | 10 lines A series of fixes from jeff's tree: 1.

So, now the client can completely run tests again since it will invoke the new tool abstraction in the same way bwctld does. This required: The 'childwait' debugging code to *always* use the context Modified the access_prio error level printing to always look in the context as well. Modified the error printing code to have a masking feature. It is now possible to make it ignore all error messages with a prio less than the specified level. (Use BWLErrOK to get everything.) Also cleaned up some other error message printing - added a convinience function for printing a 'tool' name by id.

This file can be used to set many tool specific aspects of bwctl. Many of the config file options are identical to the daemon - in fact it uses most of the same parsing code. Also modified the 'ports' parsing code to allow the specification of a single port. (and modified the tool parsing options to use the keyword 'port' instead of 'ports' to make it compatible with previous versions of bwctl - this was just a mistake on my part when I abstracted the tools) Modified the bwctl.man page to indicate the BWCTLRC env variable, and removed the now defunct environment variables that used to be used to set these daemon-features.

(A daemon can say that it will not support peers with greater than this amount of time error - including the error on the local system.) This is intended to protect bwctld from a possible DOS attack by clients requesting tests and specifying very large time errors. time.c: Modify the way the time error is specified in the context.

It was overkill, and confusing. Now, it just uses a random port in the range, and cycles through until it can open one. Moved many of the conf-file parsing options into a new function in daemon.c. This will be called by both the server and the client for implementing request-manager functionality. Reset some of the fuzz-time constants to smaller values - now that there is better process control on iperf, hopefully it will work to tighten up the schedule. Added a Memory-register function into the context. This is poor-man's memory management. When the context is free'd, and registered pointers are also free'd. Removed schedule.c. It was never used in bwctl - it was old owamp code that somehow stayed part of bwctl all this time.

The context holds the error-reporting configuration, and is used when parsing config files. However, over time more configuration initialization (with tools and NTP specifically) happened there. Now that options have been added into the config file to modify how some of those things are initialized, it was necessary to split the context creation into two parts - the first does error configuration and can then be used for parsing the files and setting the other configurable options. Modified Aaron's ntp changes a bit - if the system call ever fails, it will never be called again. It treats the system as if the timex.h header file was not available. Also fixed a bug in bwctl where the context was being passed in for arg one of I2AddrByNode instead of the I2ErrHandle. Also did a bit of prep to start moving the daemon event loop into the library to make it easier for the client to run tools in the same way as the server. ------------------------------------------------------------------------ r419 | aaron | 2008-01-14 11:31:03 -0500 (Mon, 14 Jan 2008) | 6 lines 1.

The code from GSoC06 is not as clean as I would like. It is going to take some work to fix. The main reason for going to an api interface for the tester is to do most of the testers work during test-request negotiation. That way, things that fail can fail before they effect the scheduling on the client side. That was not done - so there is a fair amount of work. This was not done for the GSoC project - most of the pieces are here - but they need to be refactored to make this a stable/supportable piece of code. Also, there as been a lot of bit-rot in the past 2 years since the last release. The same type-punning issues that took me a couple of days on owamp need to be fixed here.

Reason: There was an application timeout that closed the connection if there was no communication for 30 min. (controltimeout) Because bwctl is configured to run tests ~30 min, this means some amount of the time there will be no traffic for 30 or more min on a given control connection. Solution: Change the default value to 7200 and document this in the bwctld.conf file with the controltimeout option. 2. Some udp sessions end up being corrupt. Reason: First the buffer space between sessions was a little to small. Therefore the bwctld would kill the iperf server before the job was complete. The iperf server catches SIGINT and corrupts the results when it does. Solution: Increased the buffer space between sessions by 1 second. Then changed the kill of children that are still running at this time to a SIGKILL so it will not be caught. This will ensure that the invalid data will not be used. jeff ------------------------------------------------------------------------ r130 | boote | 2004-01-09 00:42:07 -0500 (Fri, 09 Jan 2004) | 4 lines Forgot to change function prototypes, and removing unused vars. jeff ------------------------------------------------------------------------ r129 | boote | 2004-01-09 00:30:45 -0500 (Fri, 09 Jan 2004) | 10 lines Changing the time sync check.
