Updating the nodes
Work done December 2018
Nodes 1-10 all now have ssmtp installed.
Nodes 6, 7 and 10 updated to 6.10.
Node 8 doesn't connect to the redhat subscription manager so cannot update that
Work done January 2019
Nodes 1, 2, 3, 4, 9 updated
Node 8 was updated in december but all looks. Subscription manager now inexplicably connects.
Node 5 won't connect to redhat packages.
Process
sudo subscription-manager remove --all sudo subscription-manager unregister sudo subscription-manager clean sudo subscription-manager register sudo subscription-manager refresh sudo subscription-manager attach --auto
then
yum clean all yum update
If you see an error
http://apt.sw.be/redhat/el6/en/x86_64/rpmforge/repodata/repomd.xml: [Errno 14] PYCURL ERROR 22 - "The requested URL returned error: 503 Service Unavailable"
It's due to the rpmforge repo no longer existing at that location. removing /etc/yum.repos.d/rpmforge.repo fixes the error.
If you see the error
Error: Cannot retrieve metalink for repository: epel. Please verify its path and try again
It's not due to the /etc/yum.repos.d/epel.repo file, it's because there's mirror-rpmforge-*.repo files, which need to be removed.
I then installed ssmtp using
wget http://dl.fedoraproject.org/pub/epel/6/x86_64/Packages/s/ssmtp-2.61-22.el6.x86_64.rpm rpm -ivh ssmtp-2.61-22.el6.x86_64.rpm
Identifying differences
On each node
yum list > rpmList_nodeX.txt subscriptionManager repos --list > subManList_nodeX.txt
Then got all files with
for i in {1..10}; do echo scp node$i *_node$i.txt ./; done
