not an intro but a question... moved to linux - newbie.

so.. you don't know what it means to configure a server??? erm... well you want your server to do something, so you need to configure it to make it do that thing. what do you want it to do? a server can do a million things, each done differently...

...it is also possible that you are asking (for some particular program /service/ daemon) what you do to configure the server part. Or maybe its a more general question.

background
some programs are separated into client and server parts (a client/server architecture, unsurprisingly) where one part deals with user interaction and the other part goes about the techie, "heavy lifting" part in the background.

If it is the case that this question relates to some particular program, you'll stand a far higher chance of getting a useful answer if you say what that program is.

Centos (in particular....also applies to others) can be configured as a server. In this context a server machine is one that performs certain duties for other machines on the network. So if, for example, you were trying to configure it as a file server, the server machine would have to know about which areas / how much disk it was allowed to use, who was allowed to use it, etc.

You can presumably see that this is important and that the people who packaged Centos cannot be expected to know these details on your behalf.

Here are a bunch of links related to configuring a Centos 5.0 server.

In particular, here is a tutorial to configure a sever for the needs of an ISP or web hosting server:

last week I left my server running in the lab and the teacher ask me to connect the server for home using my computer can you tell me how I can do that ?

We'll use SSH for that. It's secure and allows you to (later) tunnel about anything. BTW, next time please make a new thread for new questions. Else they get passed over too easily.

- write down the IP address of your lab server
- write down the IP address of your home computer. If you have a dynamic IP address find out in what range your IP address is.
- ask network administrator to open up firewall from your home IP (address or range) to your server port 22 protocol TCP.
- on lab server edit /etc/hosts.deny so it reads "ALL: ALL"
- on lab server edit /etc/hosts.allow so it reads "sshd: YOURIPADDRESS"
- on lab server edit your firewall script /etc/sysconfig/iptables (or use GUI) to accept traffic from IP address of home computer to lab server port 22 protocol TCP
- on lab server install openssh server
- on lab server configure /etc/ssh/sshd_conf and set "PermitRootLogin no".
- on home computer install openssh. If it runs Windows install "PuTTY".
- on home computer generate a key (ssh-keygen) as unprivileged user.
- from home computer try to connect as unprivileged user. If it fails review your commandline. If it fails again add arguments "-v -v" and post the output.
- once connection is working, copy key over from home computer. On lab server move to pubkey authentication (ssh-keygen) and edit /etc/ssh/sshd_conf and set "AllowUsers YOURUSERNAME", "PasswordAuthentication no" and "PubkeyAuthentication yes".

Hmm. I think I better redirected you to some HOWTO instead.
