Welcome to LQ!
Why are you using RH8? This is so old now, that you are wasting your time even bothering with it. RH8 is no longer supported, so there are no security updates, or recent versions of programs.
Your best bet would be to get a recent version of Linux. If you like RH, try Fedora Core which is the successor to the free RH distros. If you need stability, then Centos (Free RH clone), or even something different like Ubuntu or Debian.
