Hello,
I installed bind in CentOS release 5.6 (Final).
My DNS Server not ping alias (with cname), so the steps:
I installed this packages:
[root@centos ~]# rpm -qa | grep bind
ypbind-1.19-12.el5
bind-libs-9.3.6-16.P1.el5
bind-chroot-9.3.6-16.P1.el5
bind-9.3.6-16.P1.el5
bind-utils-9.3.6-16.P1.el5
[root@centos ~]# rpm -qa | grep nameserver
caching-nameserver-9.3.6-16.P1.el5
[root@centos ~]#
Then i'm using chroot.
[root@centos ~]# cd /var/named/
[root@centos named]# ls -las
total 32
8 drwxr-x--- 5 root named 4096 Jun 12 14:58 .
8 drwxr-xr-x 24 root root 4096 Jun 12 10:04 ..
8 drwxr-x--- 7 root named 4096 Fev 22 19:35 chroot
4 drwxrwx--- 2 named named 4096 Jun 12 14:58 data
0 lrwxrwxrwx 1 root named 45 Jun 12 14:58 localdomain.zone
-> /var/named/chroot//var/named/localdomain.zone
0 lrwxrwxrwx 1 root named 43 Jun 12 14:58 localhost.zone
-> /var/named/chroot//var/named/localhost.zone
0 lrwxrwxrwx 1 root named 44 Jun 12 14:58 named.broadcast

0 lrwxrwxrwx 1 root named 44 Jun 12 14:58 named.ip6.local
-> /var/named/chroot//var/named/named.ip6.local
0 lrwxrwxrwx 1 root named 40 Jun 12 14:58 named.local
-> /var/named/chroot//var/named/named.local
0 lrwxrwxrwx 1 root named 39 Jun 12 14:58 named.zero
-> /var/named/chroot//var/named/named.zero
0 lrwxrwxrwx 1 root named 43 Jun 12 14:58 redefariat.com
-> /var/named/chroot//var/named/redefariat.com
Now I configured the domain.
[root@centos named]# cat /var/named/chroot//var/named/redefariat.com
$TTL 43200
@ IN SOA redefariat.com. root.redefariat.com. (
2011061214 ; Serial
28800 ; Refresh
14400 ; Retry
3600000 ; Expire
86400 ; Minimum
)
@ IN NS redefariat.com.
@ IN MX 0 mail.redefariat.com
@ IN A 192.168.1.100
wwww IN CNAME redefariat.com.
ftp IN CNAME redefariat.com.
mail IN CNAME redefariat.com.
pop IN CNAME redefariat.com.
pop3 IN CNAME redefariat.com.
smtp IN CNAME redefariat.com.
rodrigo IN A 192.168.1.100
rodrigo.redefariat.com. IN A 192.168.1.100
So I put in /etc/named.caching-nameserver.conf.
options {
listen-on port 53 { 127.0.0.1; };
listen-on-v6 port 53 { ::1; };
directory "/var/named";
dump-file "/var/named/data/cache_dump.db";
statistics-file "/var/named/data/named_stats.txt";
memstatistics-file "/var/named/data/named_mem_stats.txt";
// Those options should be used carefully because they disable
port
// randomization
// query-source port 53;
// query-source-v6 port 53;
allow-query { localhost; };
allow-query-cache { localhost; };
};
logging {
channel default_debug {
file "data/named.run";
severity dynamic;
};
};
view localhost_resolver {
match-clients { localhost; };
match-destinations { localhost; };
recursion yes;
include "/etc/named.rfc1912.zones";
};
view "redefariat" {
match-clients {192.168.1.0/24;};
recursion yes;
zone "redefariat.com" {
type master;
file "/var/named/redefariat.com";
allow-transfer { none; };
};
};
The logs :
root@centos named]# tail -f /var/log/messages

I try use ping www.redefariat.com
root@centos named]# ping www.redefariat.com
ping: unknown host www.redefariat.com
What is wrong ?
Best regards,
Rodrigo Faria
