If you are on one version of RHEL and just want to keep it updated while 
making sure it does not go online, either RHN Satellite or mrepo will 
allow you to store and present Red Hat's updates to servers on your 
network.  You can even run RHN Satellite in disconnected mode where it 
does not access the Internet either but it loads updates via CDs provided 
to you by Red Hat.  mrepo is available at
