establish a mirror using rsync, this is what I run for CentOS 5.x

rsync -av --delete rsync://mirrors.kernel.org/centos/5/updates/x86_64/
latest/x86_64/
rsync -av --delete rsync://mirrors.kernel.org/centos/5/updates/i386/
latest/i386/

replace 5 with 4 to get CentOS 4.x

Then put those files on a system which your systems can access and
point yum to it. In my case an example would be to put this in your
yum config and disable all other external repositories
