　　SYNOPSIS:

　　How to set up a simple dns server with bind

　　HINT:

　　version 1.0beta1

　　This hint explains how to set up bind on your lfs.

　　I am not a bind specialist, what is written is what i

　　have understood. Don't hesitate to correct it if you

　　see mistakes or have optimizations.

　　

　　------------------------------------------------

　　1) Installation of bind

　　

　　tar zxvf bind-9.1.3.tar.gz

　　cd bind-9.1.3

　　./configure

　　make

　　make install

　　

　　cp doc/man/bin/*.1 /usr/man/man1

　　cp doc/man/bin/*.5 /usr/man/man5

　　cp doc/man/bin/*.8 /usr/man/man8

　　

　　The following configuration files are very simple. It allows you to have

　　a dns server for your local network and allows you to use the dns

　　server of your FAI when you're connected to internet.

　　

　　On this example,

　　network address : 192.168.0.0

　　domain name : zerezo.org

　　machine host name : zarba

　　machine ip : 192.168.0.51

　　

　　---------------------------------------------------

　　2) The main configuration file : /etc/named.conf

　　

　　;; Begin of file

　　

　　; General options

　　options {

　　auth-nxdomain yes;

　　directory "/var/named";

　　forward first;

　　forwarders {

　　212.47.227.206; DNS of your FAI here

　　212.47.227.207;

　　};

　　};

　　

　　; How to log

　　logging {

　　channel warning

　　{

　　file "/var/log/dns_warnings" versions 3 size 100k;

　　severity warning;

　　print-category yes;

　　print-severity yes;

　　print-time yes;

　　};

　　channel general_dns

　　{

　　file "/var/log/dns_logs" versions 3 size 100k;

　　severity info;

　　print-category yes;

　　print-severity yes;

　　print-time yes;

　　};

　　category default { warning; } ;

　　category queries { general_dns; } ;

　　};

　　

　　; zone for access to Internet

　　zone "." {

　　type hint;

　　file "named.ca";

　　};

　　

　　; zone for access to localhost

　　zone "0.0.127.in-addr.arpa" {

　　type master;

　　file "named.local";

　　};

　　

　　; zone for access to your domain

　　zone "zerezo.org" in {

　　type master;

　　notify no;

　　file "zerezo.org";

　　};

　　

　　; zone for access to your domain using ip

　　zone "0.168.192.in-addr.arpa" in {

　　type master;

　　notify no;

　　file "db.192.168.0";

　　};

　　

　　;; End of file

　　

　　------------------------------------

　　3) Configuration files for each zone

　　

　　There is a configuration file of each zone defined in named.conf.

　　These files are in /var/named . You have to create this directory.

　　

　　a) /var/named/named.ca

　　

　　This file is used when you are connected to internet.

　　I got this file on internet. It seems rather old, maybe you

　　can have a more recent one.

　　

　　; Begin of file

　　; This file holds the information on root name servers needed to

　　; initialize cache of Internet domain name servers

　　; (e.g. reference this file in the "cache . "

　　; configuration file of BIND domain name servers).

　　;

　　; This file is made available by InterNIC registration services

　　; under anonymous FTP as

　　; file /domain/named.root

　　; on server FTP.RS.INTERNIC.NET

　　; -OR- under Gopher at RS.INTERNIC.NET

　　; under menu InterNIC Registration Services (NSI)

　　; submenu InterNIC Registration Archives

　　; file named.root

　　4) Configuration of rndc

　　rndc is used to administrate bind. His developpment is not

　　fisnished but i prefer to put it in this hint rather than

　　the obsolete nslookup utility.
