You could run a Current server but that is a bit much for just a few
servers... I run a box with rsync pointing at a local mirror (for RedHat
Updates), then I manually load that "Update" directory via NFS to my
other servers and run:
  cd /mnt/rh9/Updates
  rpm -F *.rpm

After a minute or two all my rpms are up-to-date on the server, and I
unmount the drive and drop nfs.

All this could easily be done in a cron job:
  # assuming I've already opened a path through
  # both firewalls to allow NFS traffic between
  # the two servers:
  #
  /etc/rc.d/init.d/portmap start
  mount foo.bar.com:/home/RedHat/rh9 /mnt/rh9
  date
  echo "Running RH9 updates on server: Foo"
  cd /mnt/rh9/Updates
  rpm -Fv *.rpm 
  sleep 10
  cd /
  umount /mnt/rh9
  /etc/rc.d/init.d/portmap stop
  

If I put that script in the root's cron table on a server that would
update my server each time it was run and send a status message to the
root user of the server.
