I think I will need to make sure that BIND configuration was fine. So going to re-install and configure to make sure I did not miss anything. Will post the results soon.
I had removed the bind packages by the time your message was posted. But this time I did not install the bind-chroot package and used the standard bind. However, I hit exactly the same issue. [can ping ip addresses in all directions but hostname ping only works from server]. So I checked the udp/tcp port 53 but did not find them in netstat -an. I issued the following commands as found in google and did /etc/init.d/iptables restart but no joy. So looks like this might be the issue why my clients cannot reach the dns server. Any ideas on how to open udp and tcp port 53 please (CentOS 5)?
