I want to know what are the new features added in New version of Red Hat Linux 7.1 and also the list of new added software or Rpm packages.

Thank you.

Some advise for you. Go to www.redhat.com and research the information yourself, as you will find a wealth of info there. Then and only then, if you have a question post it here, but posting 10 different topics about server stuff which you are supposed to be a linux admin of, really doesn't make any sort of sense to me.
