NAME

6       yppasswdd_selinux  -  Security  Enhanced Linux Policy for the yppasswdd
7       processes
8

DESCRIPTION

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

ENTRYPOINTS

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

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       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

BOOLEANS

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.

MANAGED FILES

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.

FILE CONTEXTS

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

COMMANDS

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.
