Hi ,
OS Version : Oracle Linux 6
I'm trying to setup Oracle RAC with GNS. I've configured DNS and DHCP on TEST server. DIG works fine on the localhost, but when i trying it from a different server its failing. Not sure what i need to check. Firewall is disabled and have mentioned the DNS address in the resolv.conf file. Please suggest
[root@test Desktop]# cd /etc/named.conf
bash: cd: /etc/named.conf: Not a directory
[root@test Desktop]# cat /etc/named.conf
//
// named.conf
//
// Provided by Red Hat bind package to configure the ISC BIND named(8) DNS
// server as a caching only nameserver (as a localhost DNS resolver only).
//
// See /usr/share/doc/bind*/sample/ for example named configuration files.
