02 Fix OS Install Issues


Overview

After I rebooted CRONULLA , I found I had several issues.

Diagnosis

I found the following issues:

  1. CRONULLA was not in DNS
  2. CRONULLA was not accessible
  3. CRONULLA could not do DNS lookup

Procedure

Update Name Server

I updated the following two (2) files on GRIDCTRL to match the data presented in IP Addresses :

  • /var/named/chroot/var/named/yaocm.id.au.rr.zone
  • /var/named/chroot/var/named/yaocm.id.au.zone

And I restarted the named service.

Created resolv.conf

On CRONULLA , I created /etc/resolv.conf with the following content:

search yaocm.id.au
nameserver 192.168.1.252
nameserver 10.1.1.1

Enable eth0 on Start-up

On CRONULLA , I updated /etc/sysconfig/network-scripts/ifcfg-eth0 with the following content:

ONBOOT=yes

Change NIC to Bridged Network

I had forgotten to set the NIC to Bridged Network instead of NAT. Used VirtualBox to change the settings for the NIC.
