The code from this repository will not be further developed by the perfSONAR development team. Only security issues will still be considered and corrected from now on. See https://docs.perfsonar.net/release_candidates/4.1b1/manage_update.html#special-upgrade-notes for more information.
bwctl is a scheduling and policy daemon that wraps iperf, traceroute, owamp and a few other measurement tools. 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.
- 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/
./configure; make; make install(Note: If configure fails, try running ./bootstrap.sh first)
To check out the most recent code, do: git clone https://github.com/perfsonar/bwctl.git
To run the daemon:
bwctld -c /path/to/directory/with/bwctl-server.confThe 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/bwctl-server.conf.
To get the list of available options use:
bwctld -hbwctld -h will give you the list of options. Specifically, if you have problems you may want to use the -Z flag to run it in the foreground and have error messages come to the console in addition to syslog.
To run the client:
bwctl [options] [-c catchhost] [-s sendhost]At least a -c or a -s must be specified to indicate the direction of the test. If only one of them is specified, the local host is assumed to be the other one. If a local bwctld is not running, then bwctl will execute the bwctld functionality required to run the test.
To get the list of available options use:
bwctl -hThe 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.
