How can we regularly update the system without internet connection?
# register the system that is connected to RHN, directly or using a http proxy:
rhn_register --nox --proxy=
# or use
subscription-manager register --user --password --auto-allow ?
# sync updates from channels
reposync -p /somedir --repoid=rhel-x86_64-server-5 -l
