nslookup failing

newbie16 · 06-25-2012, 10:15 PM

Hello,

I have installed a 11.2 DB on Centos 5.7 and I am trying to do a nslookup.

I am getting the following error.

Can someone tell me what I am doing wrong? Thanks.

These are my files

/etc/sysconfig/network

Code:

[root@testhost named]# cat /etc/sysconfig/network
NETWORKING=yes
NETWORKING_IPV6=yes
#HOSTNAME=localhost.localdomain
HOSTNAME=testhost.a.pi

named.conf

Code:

// Default named.conf generated by install 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 { 192.168.100.1; };
};
include "/etc/rndc.key";


zone "localdomain." IN {
        type master;
        file "localdomain.zone";
        allow-update { none; };
};

zone "a.pi." IN {
        type master;
        file "a.pi.zone";
        allow-update { none; };
};

zone "100.168.192.in-addr.arpa." IN {
        type master;
        file "100.168.192.in-addr.arpa";
        allow-update { none; };
};

etc/hosts

Code:

[root@testhost named]# cat /etc/hosts
# Do not remove the following line, or various programs
# that require network functionality will fail.
127.0.0.1               localhost.localdomain localhost
192.168.100.90          testhost.a.pi testhost
::1             localhost6.localdomain6 localhost6

a.pi.zone

Code:

[root@testhost named]# cat a.p.zone 
$TTL    86400
@               IN SOA  localhost root.testhost (
                                        42              ; serial (d. adams)
                                        3H              ; refresh
                                        15M             ; retry
                                        1W              ; expiry
                                        1D )            ; minimum
                IN NS           localhost
localhost       IN A            127.0.0.1
testhost        IN A            192.168.100.90

in-addr.arpa

Code:

[root@testhost named]# cat 90.100.168.192.in-addr.arpa 
$ORIGIN 90.100.168.192.in-addr.arpa.
$TTL 1H
@       IN      SOA     testhost.a.pi.     root.testhost.a.pi. (      2
                                                3H
                                                1H
                                                1W
                                                1H )
90.100.168.192.in-addr.arpa.         IN NS     testhost.a.pi.
10 IN PTR  a.pi.

When I do a nslookup, this is my error.

Code:

[root@testhost named]# nslookup testhost
Server:         192.168.100.21
Address:        192.168.100.21#53

** server can't find testhost: NXDOMAIN

[root@testhost named]# nslookup testhost.a.pi
Server:         192.168.100.21
Address:        192.168.100.21#53

** server can't find testhost.a.pi: NXDOMAIN

I have disabled firewall. and selinux.
