These lines are counted for the purposes of returning line numbers in error messages but are otherwise ignored by the spawned \fBbwctld\fR. .IP \(bu 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. .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: 5 .RE .TP .BI disable_iperf Prevent \fBbwctl\fR from executing \fBIperf\fR tests .RS .IP Default: unset .RE .TP .BI disable_iperf3 Prevent \fBbwctl\fR from executing \fBIperf3\fR tests .RS .IP Default: unset .RE .TP .BI disable_nuttcp Prevent \fBbwctl\fR from executing \fBNuttcp\fR tests .RS .IP Default: unset .RE .TP .BI disable_owamp Prevent \fBbwctl\fR from executing \fBOwamp\fR tests .RS .IP Default: unset .RE .TP .BI disable_ping Prevent \fBbwctl\fR from executing \fBPing\fR tests .RS .IP Default: unset .RE .TP .BI disable_tracepath Prevent \fBbwctl\fR from executing \fBTracepath\fR tests .RS .IP Default: unset .RE .TP .BI disable_traceroute Prevent \fBbwctl\fR from executing \fBTraceroute\fR tests .RS .IP Default: unset .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: unset .RE .TP .BI iperf3_port " iperf3port" The port number(s) that \fBIperf3\fR receivers will use.

For best results, ensure that this range is different from that of nuttcp_port and thrulay_port. .PP .IP Default: unset .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.

For best results, ensure that this range is different from that of iperf_port and thrulay_port. .PP .IP Default: unset .RE .TP .BI owamp_cmd " owampcmd" The path to the \fBowping\fR command on the system. If the \fIowamp_cmd\fR does not contain a '/' character, then the PATH of the \fBbwctl\fR environment will be searched to find the \fBowping\fR executable. .RS .IP Default: owping .RE .TP .BI owamp_server_cmd " owampservercmd" The path to the \fBowampd\fR command on the system.

Currently, \fBbwctld\fR simply cycles through this range linearly. \fIowamp_port\fR must be specified 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 \fIowamp_port\fR. For example, \fB"5001\-5004"\fR would be valid, but \fB"5001 \- 5004"\fR would be invalid. .RS .PP This value must be set to a range because it is used for both the \fBOwamp\fR communication and test ports. .PP .IP Default: unset .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.

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 test_port " testport" The port number(s) that receivers of all test types will use, unless otherwise set using one of the other port variables.

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 ] [ -v ] [ -Z ]  

DESCRIPTION

bwctld is a server program designed to schedule and run Iperf, Thrulay or Nuttcp, Ping, Traceroute, Tracepath, and Owamp tests.

Aside from actually running network measurement 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.
-v
Set verbose output. Messages will only go to syslog unless the -Z option is specified.
-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.

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, Iperf3, Ping, Traceroute, Tracepath and Owamp 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 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, bwping and bwtraceroute clients are used to request the desired type of throughput, latency or traceroute 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 network measurement 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, Iperf3, Nuttcp, or Owamp 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, --ipv4
Forces bwctl to use IPv4 addresses only.
Default:
Unspecified (IPv6 is preferred).
-6, --ipv6
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, --local_address 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, --receiver recvhost[:port] [authmethod]
Specifies the host that will run the Iperf, Iperf3 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.

-s, --sender sendhost[:port] [authmethod]
Specifies the host that will run the Iperf, Iperf3 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.

-o, --flip
By default, the sender will connect to the receiver. The --flip option causes the receiver to connect to the sender. This option is not available for all test types (e.g. for iperf tests). This is most useful if the receiver is behind a firewall.
 

bwctl Test Arguments:

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

-T, --tool
Specify which throughput tester to use:
iperf
iperf3
nuttcp
Default:
None. Selects a tool that the client and server have in common
-S, --tos TOS

Set the TOS byte in the sending packets.
Default:
None.
-D, --dscp 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.)

-b, --bandwidth bandwidth
Limit UDP send rate to bandwidth (bits/sec).
Default:
1 Mb
-i, --report_interval interval
Report interval (seconds).
Default:
unset (no intervals reported)
-l, --buffer_length len
length of read/write buffers (bytes).
Default:
8 KB TCP, 1470 bytes UDP
-O, --omit seconds
Initial period of data to omit from the final statistics. This is so that you can skip past initial conditions such as TCP Slow Start. Currently only implemented by the iperf3 tool.
-P, --parallel nStreams

-t,--test_duration time
Duration of test (seconds).
Default:
10
-u, --udp

UDP test.
Default:
TCP test
-W,--dynamic_window 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 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)
 

bwping Test Arguments:

-T, --tool
Specify which throughput tester to use:
ping
owamp
Default:
None. Selects a tool that the client and server have in common
-E, --no_endpoint
Allow a ping test to run where the receiver may not have bwctl available.
-l, --packet_length length
The size of the packets to send for the ping or owamp test
Default:
Minimally sized packets
-N, --num_packets nPackets
The number of packets to send in this test
Default:
10
-i, --packet_interval seconds
The time between when each packet is sent for the test

Default:
None
 

bwtraceroute Test Arguments:

-T, --tool
Specify which throughput tester to use:
traceroute
tracepath
Default:
None. Selects a tool that the client and server have in common
-E, --no_endpoint
Allow a test to run where the receiver may not have bwctl available.
-l, --packet_length length
The size of the packets to send for the tests
Default:
Minimally sized packets
-F, --first_ttl ttl
The minimum TTL to set for traceroute. This sets the first hop in the route that will be returned. This does not work for tracepath tests.
Default:
None
-M, --max_ttl ttl
The maximum TTL to set for traceroute. This sets the last hop in the route that will be returned. This does not work for tracepath tests.
Default:
None
-t, --test_duration secondsfR
The maximum amount of time to wait for the traceroute test to finish.
Default:
10 seconds
 

Scheduling Arguments:

-a, --allow_ntp_unsync 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, --test_interval 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, --latest_time 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 10 minutes. (See -t.)
-n, --num_tests nIntervals
Number of tests to perform if the -I option is set.
Default:
Continuous
-R, --randomize 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, --output_dir dir
Specifies directory for results files if the -p option is set.
-e, --facility facility
Syslog facility to log messages to.
Default:
LOG_USER
-f, --units 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, --help

Print a help message.
-p, --print

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

Quiet output. Output as little as possible.
-r, --syslog_to_stderr

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, --version

Print version information and exit.
-v, --verbose

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

Output both sender and receiver results. By default, only the results from the appropriate side for the given tool are output. If the -p option is specified, the sender results are placed in an additional file.
-y, --format format
Specify the output format of the tool. The accepted values for format are tool specific.
Iperf:
c
[c]omma-separated output

EXAMPLES

bwctl -c somehost.example.com

Run a default 10 second TCP test as soon as possible with local as the sender and somehost.example.com as the receiver, using whichever tools they have in common. Return the results from the receive side of the test.

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.

bwping --no_endpoint -N 30 -i 0.5 --ttl 150 -c somehost.example.com

Run a ping test that sends 30 pings, one packet per half-second, with a TTL of 150 to somehost.example.com from local. If somehost.example.com does not have bwctl running, the ping test runs anyway.

bwtraceroute -T tracepath -E -c somehost.example.com

Run a tracepath test to somehost.example.com from local. If somehost.example.com does not have bwctl running, the tracepath test runs anyway.

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.

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: unset .RE .TP .BI iperf3_port " iperf3port" The port number(s) that \fBIperf3\fR receivers will use. Currently, \fBbwctld\fR simply cycles through this range linearly. \fIiperf3_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 \fIiperf3_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: unset .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 \fIowamp_cmd\fR does not contain a '/' character, then the PATH of the \fBbwctl\fR environment will be searched to find the \fBowping\fR executable. .RS .IP Default: owping .RE .TP .BI owamp_server_cmd " owampservercmd" The path to the \fBowampd\fR command on the system. If the \fIowamp_server_cmd\fR does not contain a '/' character, then the PATH of the \fBbwctl\fR environment will be searched to find the \fBowampd\fR executable. .RS .IP Default: owampd .RE .TP .BI owamp_port " owampport" The port number(s) that \fBOwamp\fR receivers will use. Currently, \fBbwctld\fR simply cycles through this range linearly. \fIowamp_port\fR must be specified 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 \fIowamp_port\fR. For example, \fB"5001\-5004"\fR would be valid, but \fB"5001 \- 5004"\fR would be invalid. .RS .PP This value must be set to a range because it is used for both the \fBOwamp\fR communication and test ports. .PP .IP Default: unset .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 ping_cmd " pingcmd" The path to the \fBping\fR command on the system. If the \fIping_cmd\fR does not contain a '/' character, then the PATH of the \fBbwctl\fR environment will be searched to find the \fBping\fR executable. .RS .IP Default: ping .RE .TP .BI ping6_cmd " ping6cmd" The path to the \fBping6\fR command on the system. If the \fIping6_cmd\fR does not contain a '/' character, then the PATH of the \fBbwctl\fR environment will be searched to find the \fBping6\fR executable. .RS .IP Default: ping6 .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 test_port " testport" The port number(s) that receivers of all test types will use, unless otherwise set using one of the other port variables. Currently, \fBbwctld\fR simply cycles through this range linearly. \fItest_port\fR must be specified 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 \fItest_port\fR. For example, \fB"5001\-5004"\fR would be valid, but \fB"5001 \- 5004"\fR would be invalid. .RS .PP This value must be set to a range because it is used for both the \fBOwamp\fR communication and test ports. .PP .IP Default: 5001-5900 .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: unset .RE .TP .BI tracepath_cmd " tracepathcmd" The path to the \fBtracepath\fR command on the system. If the \fItracepath_cmd\fR does not contain a '/' character, then the PATH of the \fBbwctl\fR environment will be searched to find the \fBtracepath\fR executable. .RS .IP Default: tracepath .RE .TP .BI tracepath6_cmd " tracepath6cmd" The path to the \fBtracepath6\fR command on the system. If the \fItracepath6_cmd\fR does not contain a '/' character, then the PATH of the \fBbwctl\fR environment will be searched to find the \fBtracepath6\fR executable. .RS .IP Default: tracepath6 .RE .TP .BI traceroute_cmd " traceroutecmd" The path to the \fBtraceroute\fR command on the system. If the \fItraceroute_cmd\fR does not contain a '/' character, then the PATH of the \fBbwctl\fR environment will be searched to find the \fBtraceroute\fR executable. .RS .IP Default: traceroute .RE .TP .BI traceroute6_cmd " traceroute6cmd" The path to the \fBtraceroute6\fR command on the system. If the \fItraceroute6_cmd\fR does not contain a '/' character, then the PATH of the \fBbwctl\fR environment will be searched to find the \fBtraceroute6\fR executable. .RS .IP Default: traceroute6 .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 bwctl_1.5.4+dfsg1.orig/doc/bwctl_ntp_conf.html0000664000076500007710000000474712560414557016267 0ustar

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.

recvhost\fR .br .B bwtraceroute [\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, \fBIperf3\fR, \fBPing\fR, \fBTraceroute\fR, \fBTracepath\fR and \fBOwamp\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 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, \fBbwping\fR and \fBbwtraceroute\fB clients are used to request the desired type of throughput, latency or traceroute 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 network measurement 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, \fBIperf3\fR, \fBNuttcp\fR, or \fBOwamp\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, \-\-ipv4\fR Forces bwctl to use IPv4 addresses only. .RS .IP Default: Unspecified (IPv6 is preferred). .RE .TP \fB\-6, \-\-ipv6\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, \-\-local_address\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, \-\-receiver\fR \fIrecvhost[:port] [authmethod]\fR Specifies the host that will run the \fBIperf\fR, \fBIperf3\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\-s, \-\-sender\fR \fIsendhost[:port] [authmethod]\fR Specifies the host that will run the \fBIperf\fR, \fBIperf3\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\-o, \-\-flip\fR By default, the sender will connect to the receiver. The --flip option causes the receiver to connect to the sender. This option is not available for all test types (e.g. for iperf tests). This is most useful if the receiver is behind a firewall. .RE .SS bwctl Test Arguments: The arguments were named to match their counterparts in \fBIperf\fR as closely as possible. .PP .TP \fB\-T, \-\-tool\fR Specify which throughput tester to use: .RS .IP \fBiperf\fR .IP \fBiperf3\fR .IP \fBnuttcp\fR .IP Default: None. Selects a tool that the client and server have in common .RE .TP \fB\-S, \-\-tos\fR \fITOS\fR .br Set the TOS byte in the sending packets. .IP Default: None. .RE .TP \fB\-D, \-\-dscp\fR \fIDSCP\fR .br Set an RFC 2474 style DSCP value for the TOS byte in the sending packets.

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.

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.

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 \-v Set verbose output. Messages will only go to syslog unless the \fB\-Z\fR option is specified. .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.

BWCTL Version 1.4.2rc3

(Bandwidth Control)
http://e2epi.internet2.edu/bwctl/
$Date$
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.)

What's Changed Since Version 1.2a

  • Allows for different throughput testing tools. Currently supported are Iperf, Thrulay and Nuttcp. Use the -T option on bwctl to specify which throughput testing tool to use. Use bwctl -h to see which are supported.
    • NOTE: Some of the throughput test options are not available for some of the testers. BWCTL does not support UDP tests, changing the output format or changing the output units with either Nuttcp or Thrulay.
  • Allows throughput tests to use multiple, parallel streams. This can be specified with the -P option in the bwctl client.
  • Allows for UDP tests with bandwidth limits of higher than 4.3Gbps. This only works with 1.3 clients and servers.
  • Allows for comma-separated value output for Iperf. Add "-y c" to the bwctl command line client to use it.
  • Allows administrators to define scripts to run at the completion of each test, allowing for results to be stored in a database, accounting tracking or any number of other tasks.
  • Improves robustness of time/scheduling.
  • Improves error handling of Iperf children processes.
  • Improves error messages for failure conditions.
What's Changed Since Version 1.1b
  • Added -f option to bwctld to allow it to run with root permissions.
  • Added better usage() messages and more information to several user prompts.
  • Fixed bug that caused all server side errors to be reported incorrectly be the client.
  • Fixed bwctld bug that disabled srcnode option.
  • Ported to Solaris.
  • Ported to OS X.
  • Removed NTP system call dependency. Added allow_unsync options.
  • Increased default -L value for bwctl.
  • Added messages to data output to indicate if Iperf was killed.
  • Modified all config options to have '_' between words.

Features

  • Supports version 2.0.x of Iperf.
  • Supports version 5.3.1 of Nuttcp.
    • NOTE: BWCTL does not support UDP tests, changing the output format or changing the output units with Nuttcp.
  • Includes built-in support for Thrulay.
    • NOTE: BWCTL does not support UDP tests, changing the output format or changing the output units with Thrulay.
  • Full IPv6 support. No options needed. If the target of a test is specified by a DNS hostname, and that name has both an IPv4 and an IPv6 address defined, the bwctl command line application prefers the IPv6 address.
  • Data from both sides of the test is returned so that sending rate can be compared with receiving rate.
  • 3-Party communication is supported. The client does not have to be on one of the test endpoint hosts.
  • A local bwctld is not required. bwctl will detect if there is a local bwctld and use it if it is there; bwctl will mimic the missing functionality if needed.
  • Port ranges for the bwctld peer connections can be specified to allow bwctld to work in firewall environments.
  • Port ranges for the throughput tests can be specified to allow passive monitoring to characterize the test streams more easily.
  • Limits the types of throughput tests that can be run. Sending a set amount of data is not supported because BWCTL needs to know how long the test will take before the test is started.
  • Supports dynamic TCP window size determination. (Currently, this is limited because the bottleneck capacity is specified as a constant in the config file. In the future, bottleneck capacity could potentially be dynamically determined using techniques such as packet dispersion.)

Requirements

  • BWCTL includes the Thrulay tester, but it would be best if Iperf 2.0.x is installed on the system.
  • The bwctld daemon prefers 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. Therefore, BWCTL requires that NTP be running to synchronize the system clock. (See the allow_unsync configuration option described in the bwctld.conf(8) manual page to see how to by-pass this requirement.) NTP should be setup correctly on the system so that bwctld can actually fetch reasonable estimates of the time error from NTP. For the NTP algorithms to work correctly, NTP MUST be configured with no fewer than 4 clocks. (See http://twiki.ntp.org/bin/view/Support/SelectingOffsiteNTPServers  for more details.)
  • gnumake may be required for the build process (see Building the Application).
  • To get good results, the endpoints will need to be well tuned. See http://www.psc.edu/networking/projects/tcptune/ and http://www-didc.lbl.gov/TCP-tuning/buffers.html for some excellent tips in that regard.

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.

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.

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.

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. .PP 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. .PP .so bwctld_conf_opts.man .SH SEE ALSO bwctl(1), bwctld(8), bwctld.limits(5), bwctld.keys(5), and the \%http://software.internet2.edu/bwctl/ web site. .PP For details on \fBIperf3\fR, see the \%https://github.com/esnet/iperf 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 \fBOwamp\fR, see the \%http://software.internet2.edu/owamp web site. .SH ACKNOWLEDGMENTS This material is based in part on work supported by the National Science Foundation (NSF) under Grant No. ANI-0314723.

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:
5
disable_iperf
Prevent bwctl from executing Iperf tests
Default:
unset
disable_iperf3
Prevent bwctl from executing Iperf3 tests
Default:
unset
disable_nuttcp
Prevent bwctl from executing Nuttcp tests
Default:
unset
disable_owamp
Prevent bwctl from executing Owamp tests
Default:
unset
disable_ping
Prevent bwctl from executing Ping tests
Default:
unset
disable_tracepath
Prevent bwctl from executing Tracepath tests
Default:
unset
disable_traceroute
Prevent bwctl from executing Traceroute tests
Default:
unset
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:
unset
iperf3_port iperf3port
The port number(s) that Iperf3 receivers will use. Currently, bwctld simply cycles through this range linearly. iperf3_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 iperf3_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:
unset
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:
unset
owamp_cmd owampcmd
The path to the owping command on the system. If the owamp_cmd does not contain a '/' character, then the PATH of the bwctl environment will be searched to find the owping executable.
Default:
owping
owamp_server_cmd owampservercmd
The path to the owampd command on the system. If the owamp_server_cmd does not contain a '/' character, then the PATH of the bwctl environment will be searched to find the owampd executable.
Default:
owampd
owamp_port owampport
The port number(s) that Owamp receivers will use. Currently, bwctld simply cycles through this range linearly. owamp_port must be specified 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 owamp_port. For example, "5001-5004" would be valid, but "5001 - 5004" would be invalid.

This value must be set to a range because it is used for both the Owamp communication and test ports.

Default:
unset
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
ping_cmd pingcmd
The path to the ping command on the system. If the ping_cmd does not contain a '/' character, then the PATH of the bwctl environment will be searched to find the ping executable.
Default:
ping
ping6_cmd ping6cmd
The path to the ping6 command on the system. If the ping6_cmd does not contain a '/' character, then the PATH of the bwctl environment will be searched to find the ping6 executable.
Default:
ping6
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
test_port testport
The port number(s) that receivers of all test types will use, unless otherwise set using one of the other port variables. Currently, bwctld simply cycles through this range linearly. test_port must be specified 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 test_port. For example, "5001-5004" would be valid, but "5001 - 5004" would be invalid.

This value must be set to a range because it is used for both the Owamp communication and test ports.

Default:
5001-5900
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:
unset
tracepath_cmd tracepathcmd
The path to the tracepath command on the system. If the tracepath_cmd does not contain a '/' character, then the PATH of the bwctl environment will be searched to find the tracepath executable.
Default:
tracepath
tracepath6_cmd tracepath6cmd
The path to the tracepath6 command on the system. If the tracepath6_cmd does not contain a '/' character, then the PATH of the bwctl environment will be searched to find the tracepath6 executable.
Default:
tracepath6
traceroute_cmd traceroutecmd
The path to the traceroute command on the system. If the traceroute_cmd does not contain a '/' character, then the PATH of the bwctl environment will be searched to find the traceroute executable.
Default:
traceroute
traceroute6_cmd traceroute6cmd
The path to the traceroute6 command on the system. If the traceroute6_cmd does not contain a '/' character, then the PATH of the bwctl environment will be searched to find the traceroute6 executable.
Default:
traceroute6
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

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:
5
disable_iperf
Prevent bwctl from executing Iperf tests
Default:
unset
disable_iperf3
Prevent bwctl from executing Iperf3 tests
Default:
unset

Default:
unset
disable_ping
Prevent bwctl from executing Ping tests
Default:
unset

Prevent bwctl from executing Tracepath tests
Default:
unset
disable_traceroute
Prevent bwctl from executing Traceroute tests
Default:
unset
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

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:
unset

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://software.internet2.edu/bwctl/ web site. .PP For details on \fBIperf3\fR, see the \%https://github.com/esnet/iperf 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 \fBOwamp\fR, see the \%http://software.internet2.edu/owamp web site. .SH ACKNOWLEDGMENTS This material is based in part on work supported by the National Science Foundation (NSF) under Grant No. ANI-0314723.

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. .PP 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. .PP .lf 1 bwctld_conf_opts.man .\" The first line of this file must contain the '"[e][r][t][v] line .\" to tell man to run the appropriate filter "t" for table. .\" .\" $Id: bwctlrc.man 493 2008-10-09 16:27:47Z aaron $ .\" .\"###################################################################### .\"# # .\"# Copyright (C) 2004 # .\"# Internet2 # .\"# All Rights Reserved # .\"# # .\"###################################################################### .\" .\" File: bwctlrc.8 .\" .\" Author: Jeff Boote and Aaron Brown .\" Internet2 .\" .\" Date: Tue Jan 06 07:44:09 EST 2009 .\" .\" Description: .\" .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 for the purposes of returning line numbers in error messages but are otherwise ignored by the spawned \fBbwctld\fR. .IP \(bu 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. .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: 5 .RE .TP .BI disable_iperf Prevent \fBbwctl\fR from executing \fBIperf\fR tests .RS .IP Default: unset .RE .TP .BI disable_iperf3 Prevent \fBbwctl\fR from executing \fBIperf3\fR tests .RS .IP Default: unset .RE .TP .BI disable_nuttcp Prevent \fBbwctl\fR from executing \fBNuttcp\fR tests .RS .IP Default: unset .RE .TP .BI disable_owamp Prevent \fBbwctl\fR from executing \fBOwamp\fR tests .RS .IP Default: unset .RE .TP .BI disable_ping Prevent \fBbwctl\fR from executing \fBPing\fR tests .RS .IP Default: unset .RE .TP .BI disable_tracepath Prevent \fBbwctl\fR from executing \fBTracepath\fR tests .RS .IP Default: unset .RE .TP .BI disable_traceroute Prevent \fBbwctl\fR from executing \fBTraceroute\fR tests .RS .IP Default: unset .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: unset .RE .TP .BI iperf3_port " iperf3port" The port number(s) that \fBIperf3\fR receivers will use. Currently, \fBbwctld\fR simply cycles through this range linearly. \fIiperf3_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 \fIiperf3_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: unset .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.

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: unset .RE .TP .BI owamp_cmd " owampcmd" The path to the \fBowping\fR command on the system. If the \fIowamp_cmd\fR does not contain a '/' character, then the PATH of the \fBbwctl\fR environment will be searched to find the \fBowping\fR executable. .RS .IP Default: owping .RE .TP .BI owamp_server_cmd " owampservercmd" The path to the \fBowampd\fR command on the system. If the \fIowamp_server_cmd\fR does not contain a '/' character, then the PATH of the \fBbwctl\fR environment will be searched to find the \fBowampd\fR executable. .RS .IP Default: owampd .RE .TP .BI owamp_port " owampport" The port number(s) that \fBOwamp\fR receivers will use. Currently, \fBbwctld\fR simply cycles through this range linearly. \fIowamp_port\fR must be specified 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 \fIowamp_port\fR. For example, \fB"5001\-5004"\fR would be valid, but \fB"5001 \- 5004"\fR would be invalid. .RS .PP This value must be set to a range because it is used for both the \fBOwamp\fR communication and test ports. .PP .IP Default: unset .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 ping_cmd " pingcmd" The path to the \fBping\fR command on the system. If the \fIping_cmd\fR does not contain a '/' character, then the PATH of the \fBbwctl\fR environment will be searched to find the \fBping\fR executable. .RS .IP Default: ping .RE .TP .BI ping6_cmd " ping6cmd" The path to the \fBping6\fR command on the system. If the \fIping6_cmd\fR does not contain a '/' character, then the PATH of the \fBbwctl\fR environment will be searched to find the \fBping6\fR executable. .RS .IP Default: ping6 .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 test_port " testport" The port number(s) that receivers of all test types will use, unless otherwise set using one of the other port variables. Currently, \fBbwctld\fR simply cycles through this range linearly. \fItest_port\fR must be specified 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 \fItest_port\fR. For example, \fB"5001\-5004"\fR would be valid, but \fB"5001 \- 5004"\fR would be invalid. .RS .PP This value must be set to a range because it is used for both the \fBOwamp\fR communication and test ports. .PP .IP Default: 5001-5900 .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: unset .RE .TP .BI tracepath_cmd " tracepathcmd" The path to the \fBtracepath\fR command on the system. If the \fItracepath_cmd\fR does not contain a '/' character, then the PATH of the \fBbwctl\fR environment will be searched to find the \fBtracepath\fR executable. .RS .IP Default: tracepath .RE .TP .BI tracepath6_cmd " tracepath6cmd" The path to the \fBtracepath6\fR command on the system.

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 40 bwctlrc.ms .SH SEE ALSO bwctl(1), bwctld(8), bwctld.limits(5), bwctld.keys(5), and the \%http://software.internet2.edu/bwctl/ web site. .PP For details on \fBIperf3\fR, see the \%https://github.com/esnet/iperf 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 \fBOwamp\fR, see the \%http://software.internet2.edu/owamp web site. .SH ACKNOWLEDGMENTS This material is based in part on work supported by the National Science Foundation (NSF) under Grant No. ANI-0314723.

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:

    L (local)
    accuracy of the local clock as reported by NTP and the local sync_fuzz parameter setting
    P (peer)
    accuracy of the peer clock as reported by NTP and the peer sync_fuzz parameter setting
    R (round trip time)
    Round Trip Time between the local host and the peer
The algorithm is:
    A + L + P + (2 * R)
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.

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 #include static BWLBoolean _TasksetAvailable(BWLContext ctx); static BWLToolDefinitionRec BWLToolNone = { "", NULL, NULL, 0, NULL, NULL, NULL, NULL, NULL }; static taskset_available = True; /* autoconf seletion of tools here... */ extern BWLToolDefinitionRec BWLToolOwamp; extern BWLToolDefinitionRec BWLToolPing; extern BWLToolDefinitionRec BWLToolTraceroute; extern BWLToolDefinitionRec BWLToolTracepath; extern BWLToolDefinitionRec BWLToolParisTraceroute; #ifdef TOOL_IPERF extern BWLToolDefinitionRec BWLToolIperf; #else #define BWLToolIperf BWLToolNone #endif extern BWLToolDefinitionRec BWLToolIperf3; #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_OWAMP, &BWLToolOwamp}, {BWL_TOOL_TRACEPATH, &BWLToolTracepath}, {BWL_TOOL_TRACEROUTE, &BWLToolTraceroute}, {BWL_TOOL_PARIS_TRACEROUTE, &BWLToolParisTraceroute}, {BWL_TOOL_PING, &BWLToolPing}, {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...

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.

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. = Building bwctl = == Prerequisites: == * I2util: You can install it via RPM, or download the source from http://software.internet2.edu/sources/I2util/ * iperf3 (optional): You can install it via RPM, or download the source from https://github.com/esnet/iperf/ == Building == ./configure; make; make install (Note: If configure fails, try running ./bootstrap.sh first) = Latest version = To check out the most recent code, do: git clone https://github.com/perfsonar/bwctl.git = Running = == Daemon == To run the daemon: % bwctld -c /path/to/directory/with/bwctld.conf 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 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.] == Client == 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 The bwctl program will allow you to run bandwidth tests like iperf, iperf3 and nuttcp. To run traceroute/tracepath, use the 'bwtraceroute' program, and to use ping/owamp, use the 'bwping' program. = Bug Reports = Before submitting a bug report, try checking out the latest version of the code, and confirm that its not already fixed.

The elements * are singly linked for minimum space and pointer manipulation overhead at * the expense of O(n) removal for arbitrary elements. New elements can be * added to the list after an existing element or at the head of the list. * Elements being removed from the head of the list should use the explicit * macro for this purpose for optimum efficiency. A singly-linked list may * only be traversed in the forward direction. Singly-linked lists are ideal * for applications with large datasets and few or no removals or for * implementing a LIFO queue. * * A list is headed by a single forward pointer (or an array of forward * pointers for a hash table header). The elements are doubly linked * so that an arbitrary element can be removed without a need to * traverse the list. New elements can be added to the list before * or after an existing element or at the head of the list. A list * may only be traversed in the forward direction. * * A simple queue is headed by a pair of pointers, one the head of the * list and the other to the tail of the list. The elements are singly * linked to save space, so elements can only be removed from the * head of the list. New elements can be added to the list before or after * an existing element, at the head of the list, or at the end of the * list. A simple queue may only be traversed in the forward direction. * * A tail queue is headed by a pair of pointers, one to the head of the * list and the other to the tail of the list. The elements are doubly * linked so that an arbitrary element can be removed without a need to * traverse the list. New elements can be added to the list before or * after an existing element, at the head of the list, or at the end of * the list. A tail queue may be traversed in either direction. * * A circle queue is headed by a pair of pointers, one to the head of the * list and the other to the tail of the list. The elements are doubly * linked so that an arbitrary element can be removed without a need to * traverse the list. New elements can be added to the list before or after * an existing element, at the head of the list, or at the end of the list. * A circle queue may be traversed in either direction, but has a more * complex end of list detection. * * For details on the use of these macros, see the queue(3) manual page. */ /* * Singly-linked List definitions. */ #define SLIST_HEAD(name, type) \ struct name { \

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_1.5.4+dfsg1.orig/Makefile.in0000664000076500007710000005575412560414557013704 0ustar # Makefile.in generated by automake 1.11.1 from Makefile.am. # @configure_input@ # Copyright (C) 1994, 1995, 1996, 1997, 1998, 1999, 2000, 2001, 2002, # 2003, 2004, 2005, 2006, 2007, 2008, 2009 Free Software Foundation, # Inc. # This Makefile.in 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. @SET_MAKE@ VPATH = @srcdir@ pkgdatadir = $(datadir)/@PACKAGE@ pkgincludedir = $(includedir)/@PACKAGE@ pkglibdir = $(libdir)/@PACKAGE@ pkglibexecdir = $(libexecdir)/@PACKAGE@ am__cd = CDPATH="$${ZSH_VERSION+.}$(PATH_SEPARATOR)" && cd install_sh_DATA = $(install_sh) -c -m 644 install_sh_PROGRAM = $(install_sh) -c install_sh_SCRIPT = $(install_sh) -c INSTALL_HEADER = $(INSTALL_DATA) transform = $(program_transform_name) NORMAL_INSTALL = : PRE_INSTALL = : POST_INSTALL = : NORMAL_UNINSTALL = : PRE_UNINSTALL = : POST_UNINSTALL = : build_triplet = @build@ host_triplet = @host@ subdir = .

(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.

Added debugging output for the scheduling process. Modified the give-up 'timeout' for the end of test to use the dieby timeout instead of the generic controltimeout. bwctld.limits: Added an example of max_time_error into the file. (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. Used to be a (double *), now it is just a double directly. (Required changes to the context code to support double in the 'union' and context access functions. endpoint.c: Modified the poor synchronized clock detection code to make the test fail.

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.
