I am having problem updating my Linux RHEL5 server. Could you tell me the files, location and content of the repository files for RHEL5.

My setting:
Under /etc/yum.repos.d/ I have one repos file only, and it is disabled “enable=0”
rhel-debuginfo.repo

yum repolist all
Loaded plugins: rhnplugin, security
repo id repo name status
rhel-debuginfo Red Hat Enterprise Linux 5Server - x86_64 - Debug disabled
rhel-x86_64-server-5 Red Hat Enterprise Linux (v. 5 for 64-bit x86_64) enabled: 9,349
rhel-x86_64-server-vt-5 RHEL Virtualization (v. 5 for 64-bit x86_64) enabled: 301
rhn-tools-rhel-x86_64-server-5 Red Hat Network Tools for RHEL Server (v.5 64-bit x86_64) enabled: 430

what i don't understand is I don't have (rhel-x86_64-server-5, rhel-x86_64-server-vt-5 and rhn-tools-rhel-x86_64-server-5) under /etc/yum.repos.d/
they are under /var/cache/yum,

What do you want to accomplish?
If you want to add a repo you should put a file in /etc/yum.repos.d/

'/etc/yum.repos.d/' :

The missing repos are probably added automatically,
when you activate your Redhat account.

.....

did you buy a license ?
red hat is not free .
you need to pay for updates

rhn_register
