If the running named process is not confined to the named_t SELinux context. Then check the labeled context for the named binaries and set the binary files to have a context of named_exec_t as shown below. The named-checkconf executable should have named_checkconf_exec_t type. # ls -Z /usr/sbin/named /usr/sbin/named-checkconf /usr/sbin/unbound-anchor system_u:object_r:named_exec_t:s0 /usr/sbin/named system_u:object_r:named_checkconf_exec_t:s0 /usr/sbin/named-checkconf system_u:object_r:named_exec_t:s0 /usr/sbin/unbound-anchor If the executable files are not labeled correctly, they may be relabeled with the chcon command, as shown, however the file system labeling is based on the SELinux ...
