17.3. Booleans
SELinux is based on the least level of access required for a service to run. Services can be run in a variety of ways; therefore, you need to specify how you run your services. Use the following Booleans to set up SELinux:
named_write_master_zones- When disabled, this Boolean prevents
namedfrom writing to zone files or directories labeled with thenamed_zone_ttype. The daemon does not usually need to write to zone files; but in the case that it needs to, or if a secondary server needs to write to zone files, enable this Boolean to allow this action. named_tcp_bind_http_port- When enabled, this Boolean allows BIND to bind an Apache port.
Note
Due to the continuous development of the SELinux policy, the list above might not contain all Booleans related to the service at all times. To list them, enter the following command:
~]$ getsebool -a | grep service_name
Enter the following command to view description of a particular Boolean:
~]$ sepolicy booleans -b boolean_name
Note that the additional policycoreutils-devel package providing the sepolicy utility is required for this command to work.
