I have tried to configure a dns server on my server, how do i become absolutely sure if it works?

acid_kewpie · 06-28-2006, 04:33 PM

well, it works if you can use it as you'd expect it to be used...

am i correct in it mapping computers gateways and such, and it associates ip's with names?
that i can do even without dns, soo?
no i'm not really sure, so hence i am asking..

If you have installed DNS server functionality on a linux machine, then the way to check if it is running is to ask it with a command like:

Code:

dig yahoo.com @localhost

If that gives you an answer, then your DNS is running. If I misunderstood your question, and you meant something like, "did I configure the DNS correctly for my machine?" then the command should just be modified to ask your DNS server. If for example your DNS server is W.X.Y.Z, then the command should be:

Code:

dig yahoo.com @W.X.Y.Z

Peace,

Mapping gateways ??
You are right that DNS associates hostnames with IP addresses.

True (ie /etc/hosts file), but DNS can make your life easier if you have a lot of computers, for instance.

Then you've come to the right place!

Well thx, i tried that dig thing and it responded, so i guess my dns is running

thx for the help

btw i'm using bind9 is it good, or is there anything better?
i just installed bind9 and it runs without config

acid_kewpie · 06-29-2006, 03:42 PM

is bind good? hehe nice one. bind is by FAR the most common DNS server ever ever (and afaik the first to get any real use), and is what the root name servers all run on. yes, it's good

BUT, i run dnsmaq as by dns requirements on my home network are miniscule, and dnsmasq is vastly simpler to configure.

how can it be simpler than install, autorun? :P
