Learning Server's
 

NewBie
Is there any sequence should be followed learn server

1)DNS
2)Mail
3)Apache

or any things is related in DNS and Mail server. or we can learn any server first as our wish....

A good install should ask just enough qns so that those services are correctly setup for you.
I'd say you should just learn whichever one seems to need adjusting.
The std install for DNS, Mail is probably ok, but Apache will just have a simple single webpage. You'll need to ad your own if that's what you want ie your own website.

could u plz. explain it in detail....
