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/bin/nrpe, /usr/sbin/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.
53
54
55
56       If you want to dontaudit all  daemons  scheduling  requests  (setsched,
57       sys_nice),  you  must turn on the daemons_dontaudit_scheduling boolean.
58       Enabled by default.
59
60       setsebool -P daemons_dontaudit_scheduling 1
61
62
63
64       If you want to allow all domains to execute in fips_mode, you must turn
65       on the fips_mode boolean. Enabled by default.
66
67       setsebool -P fips_mode 1
68
69
70
71       If  you want to allow nagios/nrpe to call sudo from NRPE utils scripts,
72       you must turn on the nagios_run_sudo boolean. Disabled by default.
73
74       setsebool -P nagios_run_sudo 1
75
76
77
78       If you want to determine whether Nagios, NRPE can access nfs file  sys‐
79       tems, you must turn on the nagios_use_nfs boolean. Disabled by default.
80
81       setsebool -P nagios_use_nfs 1
82
83
84
85       If  you  want  to  allow  system  to run with NIS, you must turn on the
86       nis_enabled boolean. Disabled by default.
87
88       setsebool -P nis_enabled 1
89

91

MANAGED FILES

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

FILE CONTEXTS

174       SELinux requires files to have an extended attribute to define the file
175       type.
176
177       You can see the context of a file using the -Z option to ls
178
179       Policy  governs  the  access  confined  processes  have to these files.
180       SELinux nrpe policy is very flexible allowing users to setup their nrpe
181       processes in as secure a method as possible.
182
183       STANDARD FILE CONTEXT
184
185       SELinux  defines  the file context types for the nrpe, if you wanted to
186       store files with these types in a different paths, you need to  execute
187       the  semanage  command  to  specify alternate labeling and then use re‐
188       storecon to put the labels on disk.
189
190       semanage fcontext -a -t nrpe_exec_t '/srv/nrpe/content(/.*)?'
191       restorecon -R -v /srv/mynrpe_content
192
193       Note: SELinux often uses regular expressions  to  specify  labels  that
194       match multiple files.
195
196       The following file types are defined for nrpe:
197
198
199
200       nrpe_etc_t
201
202       -  Set  files with the nrpe_etc_t type, if you want to store nrpe files
203       in the /etc directories.
204
205
206
207       nrpe_exec_t
208
209       - Set files with the nrpe_exec_t type, if you want to transition an ex‐
210       ecutable to the nrpe_t domain.
211
212
213       Paths:
214            /usr/bin/nrpe, /usr/sbin/nrpe
215
216
217       nrpe_var_run_t
218
219       - Set files with the nrpe_var_run_t type, if you want to store the nrpe
220       files under the /run or /var/run directory.
221
222
223
224       Note: File context can be temporarily modified with the chcon  command.
225       If  you want to permanently change the file context you need to use the
226       semanage fcontext command.  This will modify the SELinux labeling data‐
227       base.  You will need to use restorecon to apply the labels.
228
229

COMMANDS

231       semanage  fcontext  can also be used to manipulate default file context
232       mappings.
233
234       semanage permissive can also be used to manipulate  whether  or  not  a
235       process type is permissive.
236
237       semanage  module can also be used to enable/disable/install/remove pol‐
238       icy modules.
239
240       semanage boolean can also be used to manipulate the booleans
241
242
243       system-config-selinux is a GUI tool available to customize SELinux pol‐
244       icy settings.
