Hi,

you should either sign up and pay for RHN, or switch to a distribution that provides updates/packages for free. If you want to continue to use something RHEL like, you should consider using CentOS.

Evo2.

its mean that i can perform the same task in centOS , error freely

Yes, that's right.
BTW, the latest RHEL/Centos is 6.4 and you'll need to do a fresh install.
