NAME

6       ddclient_selinux - Security Enhanced Linux Policy for the ddclient pro‐
7       cesses
8

DESCRIPTION

10       Security-Enhanced Linux secures the  ddclient  processes  via  flexible
11       mandatory access control.
12
13       The  ddclient  processes  execute with the ddclient_t SELinux type. You
14       can check if you have these processes running by executing the ps  com‐
15       mand with the -Z qualifier.
16
17       For example:
18
19       ps -eZ | grep ddclient_t
20
21
22

ENTRYPOINTS

24       The ddclient_t SELinux type can be entered via the ddclient_exec_t file
25       type.
26
27       The default entrypoint paths for the ddclient_t domain are the  follow‐
28       ing:
29
30       /usr/sbin/ddtcd, /usr/sbin/ddclient
31

PROCESS TYPES

33       SELinux defines process types (domains) for each process running on the
34       system
35
36       You can see the context of a process using the -Z option to ps
37
38       Policy governs the access confined processes have  to  files.   SELinux
39       ddclient policy is very flexible allowing users to setup their ddclient
40       processes in as secure a method as possible.
41
42       The following process types are defined for ddclient:
43
44       ddclient_t
45
46       Note: semanage permissive -a ddclient_t can be used to make the process
47       type  ddclient_t permissive. SELinux does not deny access to permissive
48       process types, but the AVC (SELinux denials) messages are still  gener‐
49       ated.
50
51

BOOLEANS

53       SELinux   policy  is  customizable  based  on  least  access  required.
54       ddclient policy is extremely flexible and  has  several  booleans  that
55       allow  you  to manipulate the policy and run ddclient with the tightest
56       access possible.

MANAGED FILES

133       The SELinux process type ddclient_t can manage files labeled  with  the
134       following file types.  The paths listed are the default paths for these
135       file types.  Note the processes UID still need to have DAC permissions.

FILE CONTEXTS

212       SELinux requires files to have an extended attribute to define the file
213       type.
214
215       You can see the context of a file using the -Z option to ls
216
217       Policy  governs  the  access  confined  processes  have to these files.
218       SELinux ddclient policy is very flexible allowing users to setup  their
219       ddclient processes in as secure a method as possible.
220
221       STANDARD FILE CONTEXT
222
223       SELinux  defines the file context types for the ddclient, if you wanted
224       to store files with these types in a diffent paths, you need to execute
225       the  semanage  command  to  sepecify  alternate  labeling  and then use
226       restorecon to put the labels on disk.
227
228       semanage fcontext -a -t ddclient_var_t '/srv/myddclient_content(/.*)?'
229       restorecon -R -v /srv/myddclient_content
230
231       Note: SELinux often uses regular expressions  to  specify  labels  that
232       match multiple files.
233
234       The following file types are defined for ddclient:
235
236
237
238       ddclient_etc_t
239
240       - Set files with the ddclient_etc_t type, if you want to store ddclient
241       files in the /etc directories.
242
243
244       Paths:
245            /etc/ddtcd.conf, /etc/ddclient.conf
246
247
248       ddclient_exec_t
249
250       - Set files with the ddclient_exec_t type, if you want to transition an
251       executable to the ddclient_t domain.
252
253
254       Paths:
255            /usr/sbin/ddtcd, /usr/sbin/ddclient
256
257
258       ddclient_initrc_exec_t
259
260       -  Set files with the ddclient_initrc_exec_t type, if you want to tran‐
261       sition an executable to the ddclient_initrc_t domain.
262
263
264
265       ddclient_log_t
266
267       - Set files with the ddclient_log_t type, if you want to treat the data
268       as ddclient log data, usually stored under the /var/log directory.
269
270
271
272       ddclient_tmp_t
273
274       - Set files with the ddclient_tmp_t type, if you want to store ddclient
275       temporary files in the /tmp directories.
276
277
278
279       ddclient_var_lib_t
280
281       - Set files with the ddclient_var_lib_t type, if you want to store  the
282       ddclient files under the /var/lib directory.
283
284
285
286       ddclient_var_run_t
287
288       -  Set files with the ddclient_var_run_t type, if you want to store the
289       ddclient files under the /run or /var/run directory.
290
291
292       Paths:
293            /var/run/ddtcd.pid, /var/run/ddclient.pid
294
295
296       ddclient_var_t
297
298       - Set files with the ddclient_var_t type, if you want to store the ddcl
299       files under the /var directory.
300
301
302
303       Note:  File context can be temporarily modified with the chcon command.
304       If you want to permanently change the file context you need to use  the
305       semanage fcontext command.  This will modify the SELinux labeling data‐
306       base.  You will need to use restorecon to apply the labels.
307
308

COMMANDS

310       semanage fcontext can also be used to manipulate default  file  context
311       mappings.
312
313       semanage  permissive  can  also  be used to manipulate whether or not a
314       process type is permissive.
315
316       semanage module can also be used to enable/disable/install/remove  pol‐
317       icy modules.
318
319       semanage boolean can also be used to manipulate the booleans
320
321
322       system-config-selinux is a GUI tool available to customize SELinux pol‐
323       icy settings.
