[Josef16]

This is the error

root@localhost /]# service named restart 
Restarting named (via systemctl):  Job failed. See system logs and 'systemctl status' for details.
[FAILED]
[root@localhost /]# service named status
rndc: connect failed: 127.0.0.1#953: connection refused

In the named.conf I have this:

options {
listen-on port 53 { 127.0.0.1; any; };
listen-on-v6 port 53 { ::1; };
directory   "/var/named";
dump-file   "/var/named/data/cache_dump.db";

memstatistics-file "/var/named/data/named_mem_stats.txt";
allow-query     { localhost; any; };
recursion yes;

dnssec-validation yes;
dnssec-lookaside auto;

/* Path to ISC DLV key */

bindkeys-file "/etc/named.iscdlv.key";
managed-keys-directory "/var/named/dynamic";
};

logging {
        channel default_debug 
{
                file "data/named.run";
                severity dynamic;
        };
};

zone "." IN {
    type hint;
    file "named.ca";
};

zone "prueba.com" IN {
    type master;
    file "db.prueba.com";
};

zone "1.168.192.in.addr.arpa" IN {
    type master;
    file "1.168.192.in.addr.arpa.zone";
};
include "/etc/named.rfc1912.zones";
include "/etc/named.root.key";

In the prueba.com file I have this:

$TTL 86400
@   
IN  SOA prueba.com. root.prueba.com. (
            1;
            28800;
            7200;
                604800;
            86400;
            )

@       IN  NS      prueba.com.             
@               IN  A           192.168.1.2     

And in the 1.168.192.in.addr.arpa.zone I have this:

$TLL 86400
@   
IN  SOA prueba.com. root.prueba.com. (
            1;
            28800;
            7200;
            604800;
            86400;
            )
@   IN  NS  prueba.com. 
2   IN  PTR prueba.com.

I need to resolve this if someone knows how to fix it please reply!!!!!!
