6 yppasswdd_selinux - Security Enhanced Linux Policy for the yppasswdd
7 processes
8
10 Security-Enhanced Linux secures the yppasswdd processes via flexible
11 mandatory access control.
12
13 The yppasswdd processes execute with the yppasswdd_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 yppasswdd_t
20
21
22
24 The yppasswdd_t SELinux type can be entered via the yppasswdd_exec_t
25 file type.
26
27 The default entrypoint paths for the yppasswdd_t domain are the follow‐
28 ing:
29
30 /usr/sbin/rpc.yppasswdd, /usr/sbin/rpc.yppasswdd.env
31
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 yppasswdd policy is very flexible allowing users to setup their yppass‐
40 wdd processes in as secure a method as possible.
41
42 The following process types are defined for yppasswdd:
43
44 yppasswdd_t
45
46 Note: semanage permissive -a yppasswdd_t can be used to make the
47 process type yppasswdd_t permissive. SELinux does not deny access to
48 permissive process types, but the AVC (SELinux denials) messages are
49 still generated.
50
51
53 SELinux policy is customizable based on least access required. yppass‐
54 wdd policy is extremely flexible and has several booleans that allow
55 you to manipulate the policy and run yppasswdd with the tightest access
56 possible.

147
149 The SELinux process type yppasswdd_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.

218 SELinux requires files to have an extended attribute to define the file
219 type.
220
221 You can see the context of a file using the -Z option to ls
222
223 Policy governs the access confined processes have to these files.
224 SELinux yppasswdd policy is very flexible allowing users to setup their
225 yppasswdd processes in as secure a method as possible.
226
227 STANDARD FILE CONTEXT
228
229 SELinux defines the file context types for the yppasswdd, if you wanted
230 to store files with these types in a diffent paths, you need to execute
231 the semanage command to sepecify alternate labeling and then use
232 restorecon to put the labels on disk.
233
234 semanage fcontext -a -t yppasswdd_var_run_t '/srv/myyppasswdd_con‐
235 tent(/.*)?'
236 restorecon -R -v /srv/myyppasswdd_content
237
238 Note: SELinux often uses regular expressions to specify labels that
239 match multiple files.
240
241 The following file types are defined for yppasswdd:
242
243
244
245 yppasswdd_exec_t
246
247 - Set files with the yppasswdd_exec_t type, if you want to transition
248 an executable to the yppasswdd_t domain.
249
250
251 Paths:
252 /usr/sbin/rpc.yppasswdd, /usr/sbin/rpc.yppasswdd.env
253
254
255 yppasswdd_var_run_t
256
257 - Set files with the yppasswdd_var_run_t type, if you want to store the
258 yppasswdd files under the /run or /var/run directory.
259
260
261
262 Note: File context can be temporarily modified with the chcon command.
263 If you want to permanently change the file context you need to use the
264 semanage fcontext command. This will modify the SELinux labeling data‐
265 base. You will need to use restorecon to apply the labels.
266
267
269 semanage fcontext can also be used to manipulate default file context
270 mappings.
271
272 semanage permissive can also be used to manipulate whether or not a
273 process type is permissive.
274
275 semanage module can also be used to enable/disable/install/remove pol‐
276 icy modules.
277
278 semanage boolean can also be used to manipulate the booleans
279
280
281 system-config-selinux is a GUI tool available to customize SELinux pol‐
282 icy settings.
