Re: BIND basics

Dear all,

I am just trying to understand BIND. I would like my DNS-Server to
resolve it's own name. Is that possible or do I have to put it into
/etc/hosts?
A ping to kutter.carsten.peters.name (see zone file below) doesn't work
either. Why?

I'm no DNS expert, but I have a few suggestions.

- hostname of my machine: caluta.carsten.peters.name
- IP address: 192.168.1.3
- /etc/nsswitch.conf
- hosts: files dns
- /etc/hosts:
127.0.0.1 localhost.localdomain localhost
- /etc/resolv.conf:
nameserver 192.168.1.3
nameserver 194.179.1.100 #ISP's DNS

your ISP's nameserver shouldn't be here, it should be in named.conf, see below.

DNS caching-only running and working.
Then I added a zone to the end of /etc/named.conf
Here is the whole file:
===
// generated by named-bootconf.pl
//
// a caching only nameserver config
//
#include "/etc/rndc.key";
options {
        /*
         * If there is a firewall between you and nameservers you want
         * to talk to, you might need to uncomment the query-source
         * directive below.  Previous versions of BIND always asked
         * questions using port 53, but BIND 8.1 uses an unprivileged
         * port by default.
         */
        // query-source address * port 53;
        directory "/var/named";

          forwarders {
              194.179.1.100;
	      // could put more here if you have them
          }

};
controls {
        inet 127.0.0.1 allow { localhost; } keys { rndckey; };
};
zone "." {
        type hint;
        file "named.ca";
};
zone "localhost" {
        allow-update { none; };
        type master;
        file "localhost.zone";
};
zone "0.0.127.in-addr.arpa" {
        allow-update { none; };
        type master;
        file "named.local";
};
zone "carsten.peters.name" {
        type master;
        file "carsten.peters.name.zone";
};

You should have a reverse DNS zone here for carsten.peter.name

Here is the new zone file:
===
$TTL 86400
caluta.carsten.peters.name. IN SOA carsten.peters.name root (
5 ; serial
28800 ; refresh
14400 ; retry
3600000 ; expire
86400 ; ttl
) caluta IN NS 192.168.1.3
caluta IN A 192.168.1.3
kutter IN A 192.168.1.2
===

This looks wrong, but it could be a difference in our versions of bind. My bind9 zone looks like this:

$TTL    604800
@       IN      SOA     net.home. root.net.home. (
                        2003070410      ; Serial
                         604800         ; Refresh
                          86400         ; Retry
                        2419200         ; Expire
                         604800 )       ; Negative Cache TTL
;
        IN      NS      acephlaous.net.home.    ; name server
        IN      MX      10 mail.net.home.       ; Primary mail exchanger

mail            IN      A       209.67.232.227
antonov         IN      A       192.168.1.7
kalypso         IN      A       192.168.1.1
