Red Hat Linux is no longer free-ware.
Any new distribution of Red Hat "Enterprise" will require a license and a key.
The primary reason for charging for Red Hat is to recoup support costs.
The "free" version of Red Hat (with NO support) is now Fedora Linux.
I think that you have until sometime this April to still download the last free-ware version of Red Hat 9.
There will be no support or patches distributed for the "free" versions of Red Hat.
Bottom line, either pay for the latest version of Red Hat, or switch to Fedora or another "free" Linux distribution.
