NAME

6       nrpe_selinux - Security Enhanced Linux Policy for the nrpe processes
7

DESCRIPTION

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

ENTRYPOINTS

23       The nrpe_t SELinux type can be entered via the nrpe_exec_t file type.
24
25       The default entrypoint paths for the nrpe_t domain are the following:
26
27       /usr/s?bin/nrpe
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       nrpe policy is very flexible allowing users to setup  their  nrpe  pro‐
37       cesses in as secure a method as possible.
38
39       The following process types are defined for nrpe:
40
41       nrpe_t
42
43       Note:  semanage  permissive  -a  nrpe_t can be used to make the process
44       type nrpe_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.   nrpe
51       policy is extremely flexible and has several booleans that allow you to
52       manipulate the policy and run nrpe with the tightest access possible.

MANAGED FILES

157       The SELinux process type nrpe_t can manage files labeled with the  fol‐
158       lowing  file  types.   The paths listed are the default paths for these
159       file types.  Note the processes UID still need to have DAC permissions.

FILE CONTEXTS

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

COMMANDS

295       semanage  fcontext  can also be used to manipulate default file context
296       mappings.
297
298       semanage permissive can also be used to manipulate  whether  or  not  a
299       process type is permissive.
300
301       semanage  module can also be used to enable/disable/install/remove pol‐
302       icy modules.
303
304       semanage boolean can also be used to manipulate the booleans
305
306
307       system-config-selinux is a GUI tool available to customize SELinux pol‐
308       icy settings.
