Updating with yum
On the clients I added a repo file in /etc/yum.repos.d/companyx.y I ran yum update on the client server and it performed perfectly.
I reliazed at that point I didn't have a method of keeping the yum update repo up to date.
I then transerred the downloaded packages to the management server into /var/www/htdocs/yum.
I believe the local YUM repo can be used to perform an immediate update to a freshly installed systems.
is the The Fedora Project package manager that is able to query for information about packages, fetch packages from repositories, install and uninstall packages using automatic dependency resolution, and update an entire system to the latest available packages.
provides secure package management by enabling GPG (Gnu Privacy Guard; also known as Gnu PG) signature verification on GPG-signed packages to be turned on for all package repositories (i.e. When signature verification is enabled, packages you download and install on your system are from a trusted source, such as The Fedora Project, and were not modified during transfer.
I have created an install server/yum update server one a centralized RHEL5 Server (5.1, kernel 2.6.18-53.1.13) I am using apache2 on the server and http on the clients for both installing and updating.
This centralized install/update servers runs other aplications such as Nagios.
The management server then will not be downloading and staging the updates for that special package.
