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 allow users to resolve user passwd entries directly from
57       ldap  rather  then  using  a  sssd server, you must turn on the authlo‐
58       gin_nsswitch_use_ldap boolean. Disabled by default.
59
60       setsebool -P authlogin_nsswitch_use_ldap 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 confined applications to run with kerberos, you
72       must turn on the kerberos_enabled boolean. Enabled by default.
73
74       setsebool -P kerberos_enabled 1
75
76
77
78       If you want to allow nagios/nrpe to call sudo from NRPE utils  scripts,
79       you must turn on the nagios_run_sudo boolean. Disabled by default.
80
81       setsebool -P nagios_run_sudo 1
82
83
84
85       If  you want to determine whether Nagios, NRPE can access nfs file sys‐
86       tems, you must turn on the nagios_use_nfs boolean. Disabled by default.
87
88       setsebool -P nagios_use_nfs 1
89
90
91
92       If you want to allow system to run with  NIS,  you  must  turn  on  the
93       nis_enabled boolean. Disabled by default.
94
95       setsebool -P nis_enabled 1
96
97
98
99       If  you  want to allow confined applications to use nscd shared memory,
100       you must turn on the nscd_use_shm boolean. Disabled by default.
101
102       setsebool -P nscd_use_shm 1
103
104
105

MANAGED FILES

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

FILE CONTEXTS

177       SELinux requires files to have an extended attribute to define the file
178       type.
179
180       You can see the context of a file using the -Z option to ls
181
182       Policy  governs  the  access  confined  processes  have to these files.
183       SELinux nrpe policy is very flexible allowing users to setup their nrpe
184       processes in as secure a method as possible.
185
186       STANDARD FILE CONTEXT
187
188       SELinux  defines  the file context types for the nrpe, if you wanted to
189       store files with these types in a diffent paths, you  need  to  execute
190       the  semanage  command  to  sepecify  alternate  labeling  and then use
191       restorecon to put the labels on disk.
192
193       semanage fcontext -a -t nrpe_var_run_t '/srv/mynrpe_content(/.*)?'
194       restorecon -R -v /srv/mynrpe_content
195
196       Note: SELinux often uses regular expressions  to  specify  labels  that
197       match multiple files.
198
199       The following file types are defined for nrpe:
200
201
202
203       nrpe_etc_t
204
205       -  Set  files with the nrpe_etc_t type, if you want to store nrpe files
206       in the /etc directories.
207
208
209
210       nrpe_exec_t
211
212       - Set files with the nrpe_exec_t type, if you  want  to  transition  an
213       executable to the nrpe_t domain.
214
215
216       Paths:
217            /usr/bin/nrpe, /usr/sbin/nrpe
218
219
220       nrpe_var_run_t
221
222       - Set files with the nrpe_var_run_t type, if you want to store the nrpe
223       files under the /run or /var/run directory.
224
225
226
227       Note: File context can be temporarily modified with the chcon  command.
228       If  you want to permanently change the file context you need to use the
229       semanage fcontext command.  This will modify the SELinux labeling data‐
230       base.  You will need to use restorecon to apply the labels.
231
232

COMMANDS

234       semanage  fcontext  can also be used to manipulate default file context
235       mappings.
236
237       semanage permissive can also be used to manipulate  whether  or  not  a
238       process type is permissive.
239
240       semanage  module can also be used to enable/disable/install/remove pol‐
241       icy modules.
242
243       semanage boolean can also be used to manipulate the booleans
244
245
246       system-config-selinux is a GUI tool available to customize SELinux pol‐
247       icy settings.
