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

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

FILE CONTEXTS

206       SELinux requires files to have an extended attribute to define the file
207       type.
208
209       You can see the context of a file using the -Z option to ls
210
211       Policy  governs  the  access  confined  processes  have to these files.
212       SELinux ddclient policy is very flexible allowing users to setup  their
213       ddclient processes in as secure a method as possible.
214
215       STANDARD FILE CONTEXT
216
217       SELinux  defines the file context types for the ddclient, if you wanted
218       to store files with these types in a diffent paths, you need to execute
219       the  semanage  command  to  sepecify  alternate  labeling  and then use
220       restorecon to put the labels on disk.
221
222       semanage fcontext -a -t ddclient_var_t '/srv/myddclient_content(/.*)?'
223       restorecon -R -v /srv/myddclient_content
224
225       Note: SELinux often uses regular expressions  to  specify  labels  that
226       match multiple files.
227
228       The following file types are defined for ddclient:
229
230
231
232       ddclient_etc_t
233
234       - Set files with the ddclient_etc_t type, if you want to store ddclient
235       files in the /etc directories.
236
237
238       Paths:
239            /etc/ddtcd.conf, /etc/ddclient.conf
240
241
242       ddclient_exec_t
243
244       - Set files with the ddclient_exec_t type, if you want to transition an
245       executable to the ddclient_t domain.
246
247
248       Paths:
249            /usr/sbin/ddtcd, /usr/sbin/ddclient
250
251
252       ddclient_initrc_exec_t
253
254       -  Set files with the ddclient_initrc_exec_t type, if you want to tran‐
255       sition an executable to the ddclient_initrc_t domain.
256
257
258
259       ddclient_log_t
260
261       - Set files with the ddclient_log_t type, if you want to treat the data
262       as ddclient log data, usually stored under the /var/log directory.
263
264
265
266       ddclient_tmp_t
267
268       - Set files with the ddclient_tmp_t type, if you want to store ddclient
269       temporary files in the /tmp directories.
270
271
272
273       ddclient_var_lib_t
274
275       - Set files with the ddclient_var_lib_t type, if you want to store  the
276       ddclient files under the /var/lib directory.
277
278
279
280       ddclient_var_run_t
281
282       -  Set files with the ddclient_var_run_t type, if you want to store the
283       ddclient files under the /run or /var/run directory.
284
285
286       Paths:
287            /var/run/ddtcd.pid, /var/run/ddclient.pid
288
289
290       ddclient_var_t
291
292       - Set files with the ddclient_var_t type, if you want to store the ddcl
293       files under the /var directory.
294
295
296
297       Note:  File context can be temporarily modified with the chcon command.
298       If you want to permanently change the file context you need to use  the
299       semanage fcontext command.  This will modify the SELinux labeling data‐
300       base.  You will need to use restorecon to apply the labels.
301
302

COMMANDS

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