perfSONAR User Q&A and Other Discussion

[Andrew Lake <>]

All,

New web100 kernel packages are now available for netinstall users of the 
perfSONAR-PS toolkit. You may run 'yum update' to grab the new kernel. You 
should restart your host after the upgrade completes. Full details on this 
particular patch can be found in the previous email. Note this is just a 
kernel upgrade and the other perfSONAR-PS packages have NOT been updated.  

We have also built a new LiveCD with the latest kernel and updated 3.3.2 
packages. We don't always build a new LiveCD but did this time since a number 
of patches have been released since the LiveCD was last built. You can grab 
the latest LiveCD from http://software.internet2.edu/pS-Performance_Toolkit/

Thank you,
The perfSONAR Team
