Hi all,
I have recently joined in forum.I am new in linux.I don't know how to configure dns server in linux.Please help me and describe the step by step about dns configuration.It is used linux kernel:vmliuz(2-6-18-el5) by me.Infact which file is copied into /etc/named.conf

step 1) Pick a DNS server, e.g. BIND, MaraDNS, djbdns, dnsmasq

step 2) Read it's documentation

Why does everyone always want "step by step" details?? There are a HUGE number of steps to actuall install something like a DNS service, that's what documents are for. Learn, don't follow.

I don't know whether this was just an expression of frustration, or whether it was a genuine search for answer, but I'm going to treat it as the latter:

• in posts like this (as far as I can remember, it occurs to me that I having been watching sufficiently closely), the OP often has a low post count.
• in particular, when this question is asked of DNS (which usually means Bind, which is another issue, as it is usually not the most appropriate choice) it is usually asked with no details of the local network nor of which role the DNS server is supposed to fulfill. Anyone who knew anything about this issue would realise that this makes the question essentially unanswerable. (Not quite true; you can buy a text book which answers this question in that kind of 'answer anything' situation, but within the context of a forum, there are just too many variables to do that, and, even if you could, it would take hundreds and hundreds of hours of effort to do that.)

So, my conclusion is that its not done out of hostile intent, but out of a newbie level of awareness and the step-by-step factor is an expression of 'I don't want to think about it, I just want to add water and have it work'.

Now, of course, there is a limited extent to which you can do this and there is a limited extent to which it is constructive if you do do it.

Oh, and the other thing, I realise later, is 'step-by-step' is probably a cipher for 'you are going to ask me to do something involving the command line, so I'll probably screw up (no offense meant to the OP; I'm just assuming that you are a bit nervous of these things) if you don't describe it in painstaking detail'.

Assuming that the OP is still interested, you could start by telling what distro and version you use (Enterprize linux-5; what's that?) and what you are trying to achieve. I don't think you'll get step-by-step, unless there is already a tutorial somewhwere, but you may get useful pointers.

Well, that kernel name looks like RHEL5 kernel, so this is the relevant manual: http://www.linuxtopia.org/online_boo...5_ch-bind.html
Its fairly clearly written, considering DNS/bind is a non-trivial tool (which is where the 'step-by-step' qn comes from).
The problem is, as said above, that without a clear definition of requirements, the OP is going to have to learn how...
