   18.18.18.11	centos.linux.vmw	centos
   88.88.88.11	centos.linux.vmw	centos

4. Backup and Edit Host Resolve Addresses Configuration
   cp /etc/resolv.conf /bkup/resolv.conf.ori
   sudo vim /etc/resolv.conf

   domain linux.vmw
   search linux.vmw
   nameserver 192.168.44.2

5. Reboot the Machine
