dccd_selinux(8) SELinux Policy documentation for dccd dccd_selinux(8)
NAME dccd_selinux - Security Enhanced Linux Policy for the dccd processes
DESCRIPTION Security-Enhanced Linux secures the dccd processes via flexible manda- tory access control.
The dccd processes execute with the dccd_t SELinux type. You can check if you have these processes running by executing the ps command with the -Z qualifier.
ps -eZ | grep dccd_t
ENTRYPOINTS The dccd_t SELinux type can be entered via the "dccd_exec_t" file type. The default entrypoint paths for the dccd_t domain are the following:"
PROCESS TYPES SELinux defines process types (domains) for each process running on the system
You can see the context of a process using the -Z option to ps
Policy governs the access confined processes have to files. SELinux dccd policy is very flexible allowing users to setup their dccd pro- cesses in as secure a method as possible.
The following process types are defined for dccd:
dccm_t, dcc_client_t, dcc_dbclean_t, dccifd_t, dccd_t
Note: semanage permissive -a dccd_t
can be used to make the process type dccd_t permissive. Permissive pro- cess types are not denied access by SELinux. AVC messages will still be generated.
FILE CONTEXTS SELinux requires files to have an extended attribute to define the file type.
You can see the context of a file using the -Z option to ls
Policy governs the access confined processes have to these files. SELinux dccd policy is very flexible allowing users to setup their dccd processes in as secure a method as possible.
The following file types are defined for dccd:
- Set files with the dccd_exec_t type, if you want to transition an executable to the dccd_t domain.
- Set files with the dccd_tmp_t type, if you want to store dccd tempo- rary files in the /tmp directories.
- Set files with the dccd_var_run_t type, if you want to store the dccd files under the /run directory.
Note: File context can be temporarily modified with the chcon command. If you want to permanently change the file context you need to use the semanage fcontext command. This will modify the SELinux labeling database. You will need to use restorecon to apply the labels.
PORT TYPES SELinux defines port types to represent TCP and UDP ports.
You can see the types associated with a port by using the following command:
semanage port -l
Policy governs the access confined processes have to these ports. SELinux dccd policy is very flexible allowing users to setup their dccd processes in as secure a method as possible.
The following port types are defined for dccd:
Default Defined Ports: udp 6276,6277
Default Defined Ports: tcp 5679 udp 5679
MANAGED FILES The SELinux process type dccd_t can manage files labeled with the fol- lowing file types. The paths listed are the default paths for these file types. Note the processes UID still need to have DAC permissions.

COMMANDS semanage fcontext can also be used to manipulate default file context mappings.
semanage permissive can also be used to manipulate whether or not a process type is permissive.
semanage module can also be used to enable/disable/install/remove pol- icy modules.
semanage port can also be used to manipulate the port definitions
system-config-selinux is a GUI tool available to customize SELinux pol- icy settings.
