perfSONAR User Q&A and Other Discussion

[Aaron Brown <>]

Hi all,

A new version of BWCTL is now available. BWCTL 1.5.2 is a minor upgrade over 
the previously released version.

Some notable fixes and additions in this release:

- Use the dynamic library version of iperf3
- Fix some bugs preventing owamp tests from running in parallel
- Error out earlier when a test is being used with parameters that aren't 
valid for the test
- Allow nuttcp to be used in '--reverse' mode
- Allow setting TOS bits for ping/traceroute tests
- Allow endpoint-less mode for iperf, iperf3 and owamp tests
- Support --schedule mode that allows you to define a specific regular test 
schedule (e.g. --schedule 11:30,12:45) instead of the normal intervals

Those who are using the perfSONAR Toolkit, or otherwise have the Internet2 
RPM repository enabled, can run 'yum update' to get the latest changes. For 
those who are installing from source or prefer to install the RPMs manually, 
the newest version can be downloaded from http://software.internet2.edu/ . 
After installation, you will need to restart bwctld to use the new features. 
You can do this by running “/etc/init.d/bwctld restart”.

Please let us know if you have any questions and we look forward to 
everyone's continued feedback and support!

Thank you,
The perfSONAR-PS Development Team
