update os

[Vivek Mangal]

Hello All,
Thanks for reply
In Centos,  /etc/sysconfig/rhn/sources file is exist, which are

*** Start ***

### This describes the various package repositories (repos) that up2date
will
### query for packages. It currently supports apt-rpm, yum, and "dir" repos.

### Format is one repository (repo) entry per line, # starts comments, the
### first word on each line is the type of repo.

### The default RHN (using "default" as the url means use the one in the
### up2date config file). This is required.
#up2date default

### Note: when a channel label is required for the non up2date repos,
### the label is solely used as an internal identifier and is not
### based on the url or any other info from the repos.

### An apt style repo (the example is arjan's 2.6 kernel repo).
### The format is:
### type  channel-label      service:server        path        repo name
#apt arjan-2.6-kernel-i386 http://people.redhat.com ~arjanv/2.5/ kernel

### Note: for apt repos, there can be multiple repo names specified (space
### seperated).

### A yum style repo. The format is:
### type  channel-label     url
#yum fedora-core-development
http://download.fedora.redhat.com/pub/fedora/linux/core/development/$ARCH/

### A local directory full of packages (a "dir" repo). For example:
#dir my-favorite-rpms /var/spool/RPMS/

# Multiple versions of all repos except "up2date" can be used. Dependencies
# can be resolved "cross-repo" if need be.

yum centos4-Base http://mirror.centos.org/centos/4/os/$ARCH/
yum centos4-Updates http://mirror.centos.org/centos/4/updates/$ARCH/
yum centos4-extras http://mirror.centos.org/centos/4/extras/$ARCH/
#yum centos4-contrib http://mirror.centos.org/centos/4/contrib/$ARCH/
yum centos4-addons http://mirror.centos.org/centos/4/addons/$ARCH/
#yum centos4-centosplus http://mirror.centos.org/centos/4/centosplus/$ARCH/
 *** End ***

Do you have the /etc/sysconfig/rhn/sources file ?
The steps I'd given was for RHEL based on up2date. I'm not sure whats
the CENTOS equivalent for the /etc/sysconfig/rhn/sources file.
Maybe someone with more exp on centos can help you. btw if you do have
the above file, please post the contents of it.
