I have recived an approvel to test out the option to run a Dedicated server in school,
For this i have P4 2Ghrz with 1024ram and out school's T3 connection.

I want to Run Websites on it, i preffer Redhat running on it.

now my quastion is where do i start ? step by step..
from installing the softwares till opening account.
is there any place that can give me that kind of information ?

Ok, this is my recommendation (may not be in the correct order, can't remember when installing):

(1) Go buy Red Hat 7.1

(2) Use disk druid and setup partitions:

/ = 250 MB
/boot = 50 MB
/var = 2000 MB
/usr = 2000 MB
/swap = 500 MB
/home = rest of HD

(3) Install it...Do a basic server install

(4) Install DNS and Webservices...no GUI

(5) You'll need an IP address, subnet mask and default gateway

(6) Set the root password

(7) NO FIREWALL

(8) When you finish and it reboots, login as root with the password you setup in step 6 above

(9) try to ping out

That should give you a basic system that will work. There are things that do not get installed, such as PROFTP and no control panel. But this should be enough to get you going.
