what's wrong with my Ubuntu 11.10 bind9 configuration?
- by John Bowlinger
I've followed several tutorials on installing your own nameservers and I'm pretty much at my wit's end, because I cannot get them to resolve. Note, the actual domain and ip address has been changed for privacy to example.com and 192.168.0.1. My named.conf.local file:
zone "example.com" {
type master;
file "/var/cache/bind/example.com.db";
};
zone "0.168.192.in_addr.arpa" {
type master;
file "/var/cache/bind/192.168.0.db";
};
My named.conf.options file:
options {
forwarders {
192.168.0.1;
};
auth-nxdomain no; # conform to RFC1035
listen-on-v6 { any; };
};
My resolv.conf file:
search example.com.
nameserver 192.168.0.1
My Forward DNS file:
ORIGIN example.com.
$TTL 86400
@ IN SOA ns1.example.com. root.example.com. (
2012083101 ; Serial
604800 ; Refresh
86400 ; Retry
2419200 ; Expire
3600 ) ; Negative Cache TTL
example.com. NS ns1.example.com.
example.com. NS ns2.example.com.
example.com. MX 10 mail.example.com.
@ IN A 192.168.0.1
ns1.example.com IN A 192.168.0.1
ns2.example.com IN A 192.168.0.2
mail IN A 192.168.0.1
server1 IN A 192.168.0.1
gateway IN CNAME ns1.example.com.
headoffice IN CNAME server1.example.com.
smtp IN CNAME mail.example.com.
pop IN CNAME mail.example.com.
imap IN CNAME mail.example.com.
www IN CNAME server1.example.com.
sql IN CNAME server1.example.com.
And my reverse DNS:
$ORIGIN 0.168.192.in-addr.arpa.
$TTL 86400
@ IN SOA ns1.example.com. root.example.com. (
2009013101 ; Serial
604800 ; Refresh
86400 ; Retry
2419200 ; Expire
3600 ) ; Negative Cache TTL
1 PTR mail.example.com.
1 PTR server1.example.com.
2 PTR ns1.example.com.
Yet, when I restart bind9 and do:
host ns1.example.com localhost
I get:
Using domain server:
Name: localhost
Address: 127.0.0.1#53
Aliases:
Host ns1.example.com.example.com not found: 2(SERVFAIL)
Similarly, for:
host 192.168.0.1 localhost
I get:
;; connection timed out; no servers could be reached
Anybody know what's going on? Btw, my domain name "www.example.com" that I've used in this question is being forwarded to my ISP's nameservers. Would that affect my bind9 configuration? I want to learn how to do set up nameservers on my own for learning, so that is why I'm going through all this trouble.
