Hi Folks,

Just a quick addition to the above, I have currently been installing a couple of RHEL 7.5 servers. They are both running ntp and have been installed from a RHEL 7.5 image and then fully updated from the current Red Hat online repos, so I decided just to tick this one off the build and when I checked the server I find.

Code:
[root@fbakirpomd4 bin]# ntpd --version
ntpd 4.2.6p5

exit 0
[root@fbakirpomd4 bin]# systemctl status ntpd

These servers are built from an already supplied Kick Start file, which to be fair is pretty large - much larger than it needs to be to be fair with a huge amount of configuration stuff in the file.

The repo's are setup in the Kick Start as follows;

Code:
[root@fbakirpomd4 bin]# yum repolist
Loaded plugins: product-id, search-disabled-repos, subscription-manager, versionlock
repo id                                            repo name                                                                               status
rhel-7-server-eus-rpms/x86_64                      Red Hat Enterprise Linux 7 Server - Extended Update Support (RPMs)                      21,608
rhel-7-server-rpms/x86_64                          Red Hat Enterprise Linux 7 Server (RPMs)                                                21,088
repolist: 42,696
[root@fbakirpomd4 bin]#

So I'll have a hunt around to try and come up with a reason for the package not updating - a yum update was run against the server.

Regards
