Ok,
Here is the update:
I deleted the line: ROOTDIR="/var/named/chroot"
on /etc/sysconfig/named
restarted named and now, it shows me:
WARNING: key file (/etc/rndc.key) exists, but using default configuration file (/etc/rndc.conf) rndc: connection to remote host closed This may indicate that * the remote server is using an older version of the command protocol, * this host is not authorized to connect, * the clocks are not synchronized, or * the key is invalid. named (pid 3442) is running..
but, after this, the Nameservers and DNS are working and solving.
Anything to fix those awful messages?
