PeteDotCom -> Networking -> Linux -> Configuring DNS ->   The following setup is tailored for slackware version 7. If your Linux is different, please refer to your manual. To get started edit your /etc/hosts file This file describes a number of hostname-to-address mappings for the TCP/IP subsystem. the following is an example. 192.168.1.12 g1c2.3604e1 g1c2 192.168.1.22 g2c2.3604e1 g2c2 The first part is the ip address of each address of each host, the second part is the name of each host, and the last bit is the alias of each host.   Now edit /etc/host.conf    make sure it is like the following order hosts, bind multi on Now edit /etc/named.conf   the following is a sample, modify accordingly /* * A simple BIND 8 configuration */ options { directory "/var/named";       #create /var/named if necessary }; logging { category lame-servers { null; }; category cname { null; }; };   zone "3604e1" in {         #change 3604e1 to the name of your domain type master; file "named.3604e1";     #change this to named.youdomain }; zone "1.168.192.in-addr.arpa" in {    #change this to your network address type master; file "named.192.168.1";      *modify accordingly }; #zone "bar.org" in { # type slave; # file "bar.hosts"; # masters { 192.168.1.1; }; #}; zone "." in { type hint; file "named.ca"; }; zone "0.0.127.in-addr.arpa" in { type master; file "named.local"; };   now edit your /etc/resolv.conf   the following is a sample domain 3604e1      #modify 3604e1 to your domain name search 3604e1      #same as above nameserver 192.168.1.22    #modify to your nameserver address   now edit your /var/named/named.192.168.1    create directory /var/named if necessary   also modify the ip address to what your network is. @ IN SOA g2c2.3604e1 ( 2000100900 ; Serial number YYMMDD### 43200 ; Refresh frequency: twice per day 3600 ; Retry rate: refresh each hour 172800 ; Time to expire: two days 86400) ; Time to wait: one day ; Nameservers in our domain IN NS g2c2.3604e1 ; ; Hosts in the domain 22 IN PTR g2c2.3604e1. ; Master Server 24 IN PTR g2c2.3604e1. (first part (22 & 24) is the last part of the ip address of the host. followed by IN PTR and then the host name.)   now edit the /var/named/named.3604e1    Change this to named.yourdomain ;Master domain name file for 3612.com @ IN SOA g2c2.3604e1. hostmaster.3604e1 ( 001023000 ; Serial number YYMMDD### 43200 ; Refresh frequency: twice per day 3600 ; Retry rate: refresh each hour 172800 ; Time to expire: two days 86400) ; Time to wait: one day ;nameservers in our domain IN NS g2c2.3604e1.
