RHN registration

You must have read the the terms of the agreement before you downloaded redhat software. Trial versions are typically meant to be used for no longer than 30 days. It is perfectly possible that there will be no technical limitations preventing you from using the platform longer. Still not legal though.

So if you haven't used it for 30 days, yep you can keep testing. If longer (check the agreement to see if it is indeed 30 days) you should stop using the software.

Or you can install CentOS. It's basically the same as Red Hat but free.

centos has not yet released version 6.

Thanks.

So, what's the use of the subscription number that they sent to me ? I knew it should put when I start the rhn_register but so far I didn't use it.  And I found that "yum" work fine....

Frankly, this is a evaluation server and we will bought the license once we confirm to use it for production environment.

The subscription number is "the" primary means by which you can find the services the system is entitled to use. (see the info at https://access.redhat.com)

So, this number is nothing to do with yum update, which I could still download the packages, correct ?
