Hey Folks,

Both of these issues should now be fixed so you should be able to do a "yum update" on your hosts. Let us know if you run into any issues.

Cheers,
Aaron

Greetings;

See below for a note from the CentOS project (upstream provider of the operating system that the pS Performance Toolkit uses) related to new versions of the base software.  This has two implications for the pSPT community:

1) It has come to our attention via some testing of this upgrade that there are conflicts with some of the perl libraries that will require manual action on the part of Toolkit deployers.  The pSPT team is working to address these with our own software release, but in the meantime we suggest that administrators do the following when upgrading:

yum --exclude=perl* update

This will allow an upgrade of all packages on the host, with the exception of the perl libraries that we have identified conflicts.  Upgrading the perl packages will result in some of the base perfSONAR software being unable to operate.  We apologize for any trouble this will cause, and will advise the community of a  proper fix when one is available.  

2) There will be a new kernel available for CentOS 6 / pSPT 3.3.x.  If you are a NetInstall user running any version of the Toolkit, a 'yum update' may give you a new non-web100 kernel and therefore break access to NDT/NPAD. Consult our FAQ for more info:http://psps.perfsonar.net/toolkit/FAQs.html#Q30.  The curious can find the CVE here:

http://rhn.redhat.com/errata/RHSA-2013-1645.html

Our read of the CVE indicates that if you are using UDP offload (a rare setting that is not enabled by default) there is a risk of exploit via remote DDoS to gain entry to the system.  If you haven't enabled this, you should not be vulnerable.  We are in the process of building and testing a new kernel, and will alert you when we have our web100 patched version available. We'll try to have it ready as soon as possible.

Thanks, and let us know if there are any questions or concerns.

Subject: [CentOS-announce] Release for CentOS-6.5 i386 and x86_64

-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1

We are pleased to announce the immediate availability of CentOS-6.5
install media for i386 and x86_64 Architectures. Release Notes for 6.5
are available at http://wiki.centos.org/Manuals/ReleaseNotes/CentOS6.5 -
we recommend everyone looks through those once.

CentOS-6.5 is based on the upstream release EL 6.5 and includes packages
from all variants. All upstream repositories have been combined into
one, to make it easier for end users to work with.

There are many fundamental changes in this release, compared with the
past CentOS-6 releases, and we highly recommend everyone stufy the
Release Notes as well as the upstream Techical Notes about the changes
and how they might impact your installation.

All updates released since upstream 6.5 release are also released to the
CentOS-6.5 mirrors.

Everyone who has centos-cr repositories enabled and in use, would
already be running CentOs-6.5 as of one week ago and will notice only
the centos-release rpm update today.

+++++++++++++++++++++++
Upgrading from CentOS-4 or CentOS-5:

We recommend everyone run through a reinstall rather than attempt an
inplace upgrade from CentOS-4 or CentOS-5.

+++++++++++++++++++++++
Upgrading from CentOS-6.0 / 6.1 / 6.2 / 6.3 or 6.4

Unless you have edited your yum configs, a 'yum update' should move your
machine seamlessly from any previous CentOS-6.x release to CentOS-6.5

+++++++++++++++++++++++
Downloading CentOS-6.5 for new installs:

When possible, consider using torrents to run the downloads. Usually its
also the fastest means to download the distro.

Torrent files for the DVD's are available at :
http://mirror.centos.org/centos/6.5/isos/i386/CentOS-6.5-i386-bin-DVD1to2.torrent
http://mirror.centos.org/centos/6.5/isos/x86_64/CentOS-6.5-x86_64-bin-DVD1to2.torrent

You can also use a mirror close to you :
http://www.centos.org/modules/tinycontent/index.php?id=30

Most mirrors will allow direct DVD downloads over http, ftp and rsync.

Please keep in mind that not all mirrors are currently updated, some
might take upto another 24 hours before they have all the content.

We have also made efforts to try and ensure that most install types and
roles can be run from DVD-1 itself.

currently under development for CentOS-6.5 and will be released in the
coming days. Everyone looking to join and help with the CentOS Cloud
efforts is encouraged to join the CentOS-Virt list where such issues
are discussed ( http://lists.centos.org/mailman/listinfo/centos-virt ).

+++++++++++++++++++++++
Getting Help:

The best place to start when looking for help with CentOS is at the wiki
( http://wiki.centos.org/GettingHelp ) which lists various options and
communities who might be able to help. If you think there is a bug in
the system, do report it at http://bugs.centos.org/ - but keep in mind
that the bugs system is *not* a support mechanism.

+++++++++++++++++++++++
Metups and training sessions

The next CentOS Dojo is going to take place at Austin, TX, USA on the
6th December 2013. Details on the day, venue and registration are
available at http://wiki.centos.org/Events/Dojo/Austin2013

As 2014 comes up, we've started planning for the Dojo Schedules for
the next year. If you would like to get involved in helping
organising, running, presenting or sponsoring a Dojo or even just want
more detail do get in touch with us at the CentOS Promo list
(http://lists.centos.org/mailman/listinfo/centos-promo)


+++++++++++++++++++++++
Contributing and joining the project:

We are always looking for people to join and help with various things in
the project. If you are keen to help out a good place to start is the
wiki page at http://wiki.centos.org/Contribute . If you have questions
or a specific area you would like to contribute towards that is not
covered on that page, feel free to drop in on
# for a chat or email the centos-devel list
(http://lists.centos.org).

+++++++++++++++++++++++
Thanks to everyone who contributed towards making CentOS 6.5, specially
the effort put in, as always, by the QA and Build team.

A special shout out to all the donors who have contributed hardware,
network connectivity, hosting and resources over the years. The CentOS
project now has a fairly well setup resource pool, purely thanks to the
donors.

Enjoy!
