easiest way to keep a Redhat 9 box

[<caldcv () students fccj org>]

Hi,

  I just installed Redhat 9, and I'm some-what used to using Debian and its wonderful apt-get command, however I 
noticed Redhat lacked such a capability. However, they had the RHN (Redhat Network) option which costs money.
 
 Is there a third-party piece of software that auto-updates a Redhat box?
