Since
vish786 has already given you a very clear answer to your question, am just offering an advice.
Use a more modern distro, even though educational syllabus might require you to use Red Hat 9.0, the other distros are much better and yet similar and on topic towards your course. If that's the reason, of course. I'd suggest
Fedora 6 or 7 .. or my personal favorite, but slightly non-usable for your course,
Ubuntu
