linux: bind dns server

you can use bind to set up your own dns server on a linux box

get it from http://www.bind9.net/download for source file or get your rpms from installation package

i use rpms for easier installation procedure ;D

you'll need the ff:
bind, bind-utils, bind-libs, bind-chroot

your /var/named/chroot/etc/named.conf should contain:
// Default named.conf generated upon installation of bind-9.2.4-30.el4_7.2
options {
        directory "/var/named";
        dump-file "/var/named/data/cache_dump.db";
        statistics-file "/var/named/data/named_stats.txt";
        forwarders {8.8.8.8; 8.8.4.4;}; // i use google's dns servers
        forward only;
};
include "/etc/rndc.key";


your /etc/resolv.conf should have:
nameserver 127.0.0.1

tada!!
