NAME

6       dictd_selinux - Security Enhanced Linux Policy for the dictd processes
7

DESCRIPTION

9       Security-Enhanced Linux secures the dictd processes via flexible manda‐
10       tory access control.
11
12       The dictd processes execute with the  dictd_t  SELinux  type.  You  can
13       check  if  you have these processes running by executing the ps command
14       with the -Z qualifier.
15
16       For example:
17
18       ps -eZ | grep dictd_t
19
20
21

ENTRYPOINTS

23       The dictd_t SELinux type can be entered via the dictd_exec_t file type.
24
25       The default entrypoint paths for the dictd_t domain are the following:
26
27       /usr/sbin/dictd
28

PROCESS TYPES

30       SELinux defines process types (domains) for each process running on the
31       system
32
33       You can see the context of a process using the -Z option to ps
34
35       Policy  governs  the  access confined processes have to files.  SELinux
36       dictd policy is very flexible allowing users to setup their dictd  pro‐
37       cesses in as secure a method as possible.
38
39       The following process types are defined for dictd:
40
41       dictd_t
42
43       Note:  semanage  permissive  -a dictd_t can be used to make the process
44       type dictd_t permissive. SELinux does not  deny  access  to  permissive
45       process  types, but the AVC (SELinux denials) messages are still gener‐
46       ated.
47
48

BOOLEANS

50       SELinux policy is customizable based on least access  required.   dictd
51       policy is extremely flexible and has several booleans that allow you to
52       manipulate the policy and run dictd with the tightest access possible.

PORT TYPES

167       SELinux defines port types to represent TCP and UDP ports.
168
169       You can see the types associated with a port  by  using  the  following
170       command:
171
172       semanage port -l
173
174
175       Policy  governs  the  access  confined  processes  have to these ports.
176       SELinux dictd policy is very flexible allowing  users  to  setup  their
177       dictd processes in as secure a method as possible.
178
179       The following port types are defined for dictd:
180
181
182       dict_port_t
183
184
185
186       Default Defined Ports:
187                 tcp 2628
188

MANAGED FILES

190       The SELinux process type dictd_t can manage files labeled with the fol‐
191       lowing file types.  The paths listed are the default  paths  for  these
192       file types.  Note the processes UID still need to have DAC permissions.

FILE CONTEXTS

235       SELinux requires files to have an extended attribute to define the file
236       type.
237
238       You can see the context of a file using the -Z option to ls
239
240       Policy governs the access  confined  processes  have  to  these  files.
241       SELinux  dictd  policy  is  very flexible allowing users to setup their
242       dictd processes in as secure a method as possible.
243
244       STANDARD FILE CONTEXT
245
246       SELinux defines the file context types for the dictd, if you wanted  to
247       store  files  with  these types in a diffent paths, you need to execute
248       the semanage command  to  sepecify  alternate  labeling  and  then  use
249       restorecon to put the labels on disk.
250
251       semanage fcontext -a -t dictd_var_run_t '/srv/mydictd_content(/.*)?'
252       restorecon -R -v /srv/mydictd_content
253
254       Note:  SELinux  often  uses  regular expressions to specify labels that
255       match multiple files.
256
257       The following file types are defined for dictd:
258
259
260
261       dictd_etc_t
262
263       - Set files with the dictd_etc_t type, if you want to store dictd files
264       in the /etc directories.
265
266
267
268       dictd_exec_t
269
270       -  Set  files  with the dictd_exec_t type, if you want to transition an
271       executable to the dictd_t domain.
272
273
274
275       dictd_initrc_exec_t
276
277       - Set files with the dictd_initrc_exec_t type, if you want  to  transi‐
278       tion an executable to the dictd_initrc_t domain.
279
280
281
282       dictd_var_lib_t
283
284       -  Set  files  with  the dictd_var_lib_t type, if you want to store the
285       dictd files under the /var/lib directory.
286
287
288
289       dictd_var_run_t
290
291       - Set files with the dictd_var_run_t type, if you  want  to  store  the
292       dictd files under the /run or /var/run directory.
293
294
295
296       Note:  File context can be temporarily modified with the chcon command.
297       If you want to permanently change the file context you need to use  the
298       semanage fcontext command.  This will modify the SELinux labeling data‐
299       base.  You will need to use restorecon to apply the labels.
300
301

COMMANDS

303       semanage fcontext can also be used to manipulate default  file  context
304       mappings.
305
306       semanage  permissive  can  also  be used to manipulate whether or not a
307       process type is permissive.
308
309       semanage module can also be used to enable/disable/install/remove  pol‐
310       icy modules.
311
312       semanage port can also be used to manipulate the port definitions
313
314       semanage boolean can also be used to manipulate the booleans
315
316
317       system-config-selinux is a GUI tool available to customize SELinux pol‐
318       icy settings.
