    I followed the instructions on this link:
    Installation Of BIND As A Secondary (Slave) DNS Server On CentOS(http://www.howtoforge.com/installation-of-bind-as-a-secondary-slave-dns-server-on-centos)

    I created another slave DNS & here's the error I've got, I followed the intructions from 1 to 4.

    What's the output of
    Code:
    ls -la /var/named/chroot/etc/
    ?

    Is SELinux disabled on both systems?

    SELinux

    Hi Falco,

    How to verify that? Actually we have Primary & slave DNS already. Both are working fine. So this is a 3rd slave DNS. The reason for me to do this is I'm going to replace the 2nd slave. They are all CENTOS.

    /etc/named.conf

    Here's my /etc/named.config

    options {

    dump-file "/var/named/data/cache_dump.db";

    /*
    * 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;
    allow-transfer {208.99.198.184/32;};
    };

    //

    controls {

    zone "localhost" IN {

    I encounter this error when I do start the service named

    What are the outputs of
    Code:
    getenforce
    on both systems?

    Do you use ISPConfig 3?

    I just disable the firewall ip tables & it did works...

    Thank you falco. Will you be able to suggest a basic or important security on this DNS server?


    Thank you.

    C:\Users\1>nslookup 192.168.0.4
    Server: UnKnown
    Address: 192.168.0.4

    *** UnKnown can't find 192.168.0.4: Non-existent domain


    here's when I tried in slave dns:

    [root@dns03 ~]# nslookup 192.168.0.4
    Server: 192.168.0.1
    Address: 192.168.0.1#53

    ** server can't find 4.0.168.192.in-addr.arpa.: NXDOMAIN

    But on the primary DNS shows name when I did this.
