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 at 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 at centos ~]# rpm -qa | grep nameserver
caching-nameserver-9.3.6-16.P1.el5
[root at centos ~]# 

Then i'm using chroot.

[root at centos ~]# cd /var/named/
[root at 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
-> /var/named/chroot//var/named/named.broadcast
0 lrwxrwxrwx  1 root  named   37 Jun 12 14:58 named.ca
-> /var/named/chroot//var/named/named.ca
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 at 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 :

I try use ping www.redefariat.com

root at centos named]# ping www.redefariat.com
ping: unknown host www.redefariat.com

What is wrong ?

Best regards,
