perfSONAR User Q&A and Other Discussion

[Michael Johnson <>]

All,

New web100 kernel packages are now available for users of the perfSONAR 
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 packages have NOT 
been updated. Please let us know if you have any questions or issues.

Also note that the CentOS project released another new kernel while we were 
in the process of building the one referenced in the previous e-mail. That 
update is also included in this release. For more information about that CVE, 
see here:

Thank you,
The perfSONAR Team
