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.  As we often do with incremental kernel updates, we will 
not be providing a new LiveCD for this particular update. Please let us know 
if you have any questions or issues.

Thank you,
The perfSONAR Team
