Depends where you got the CD's from , some magazine-cover type compilations include loads of extra's, some don't, my question is why RedHat9 ? why not Fedora (if you want the redhat family?) unless you have RedHat Enterprise version.
At the very least you will have Apache, PHP, PERL, Python, bash shell, buildtools & compilers, named, proftpd, MySQL/PostgreSQL + all the usual GNU stuff, Gnome desktop (probably with option for KDE/Ice etc) and probably OpenOffice, Gimp etc etc.
The only thing missing from my last Fedora Core4 install (indeed any redhat install) was something like mplayer for playing wmv's and asf's etc but `yum install mplayer` normally fixes that.
Is there something specifically you want it to have ?
MVC is the current buzz in web application architectures. It comes from event-driven desktop application design and doesn't fit into web application design very well. But luckily nobody really knows what MVC means, so we can call our presentation layer separation mechanism MVC and move on. (Rasmus Lerdorf)
