I installed CentOS 4 on a new box to use as a DNS server. It is a basic server install. I configured named and it is all up and running fine. It just isn't listening on Port 53. It also (obviously) does not respond to DNS requests. Requests from the machine itself are processed just fine, so the service is working. It just can't be used by other machines. Not good for a public DNS server. I did install and turn on SELinux. Maybe that was a mistake? I've not worked with SELinux before. Thanks for any ideas, Michael
