The servers allow lookup to proceed to an external DNS so that the rest of the internet can be accessed if desired. The AOC cluster uses the NRAO name servers {mala, zia}.aoc.nrao.edu. This is configuration is set in /etc/resolv.conf

restorecon
on the files will usually ensure that the appropriate context is applied. When files are moved or copied from elsewhere (e.g., during patching) they may be labelled incorrectly and daemon startup will be incomplete or unsuccessful. In addtion, an SELinux bool is set to allow named to write the zone files. This was set using setsebool -P named_write_master_zones on
