NAME

6       rlogind_selinux  -  Security Enhanced Linux Policy for the rlogind pro‐
7       cesses
8

DESCRIPTION

10       Security-Enhanced Linux secures  the  rlogind  processes  via  flexible
11       mandatory access control.
12
13       The  rlogind processes execute with the rlogind_t SELinux type. You can
14       check if you have these processes running by executing the  ps  command
15       with the -Z qualifier.
16
17       For example:
18
19       ps -eZ | grep rlogind_t
20
21
22

ENTRYPOINTS

24       The  rlogind_t  SELinux type can be entered via the rlogind_exec_t file
25       type.
26
27       The default entrypoint paths for the rlogind_t domain are  the  follow‐
28       ing:
29
30       /usr/lib/telnetlogin, /usr/sbin/in.rlogind, /usr/kerberos/sbin/klogind
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       rlogind  policy  is very flexible allowing users to setup their rlogind
40       processes in as secure a method as possible.
41
42       The following process types are defined for rlogind:
43
44       rlogind_t
45
46       Note: semanage permissive -a rlogind_t can be used to make the  process
47       type  rlogind_t  permissive. SELinux does not deny access to permissive
48       process types, but the AVC (SELinux denials) messages are still  gener‐
49       ated.
50
51

BOOLEANS

53       SELinux policy is customizable based on least access required.  rlogind
54       policy is extremely flexible and has several booleans that allow you to
55       manipulate  the  policy and run rlogind with the tightest access possi‐
56       ble.
57
58
59
60       If you want to allow users to resolve user passwd entries directly from
61       ldap  rather  then  using  a  sssd server, you must turn on the authlo‐
62       gin_nsswitch_use_ldap boolean. Disabled by default.
63
64       setsebool -P authlogin_nsswitch_use_ldap 1
65
66
67
68       If you want to allow all domains to execute in fips_mode, you must turn
69       on the fips_mode boolean. Enabled by default.
70
71       setsebool -P fips_mode 1
72
73
74
75       If  you  want  to allow confined applications to run with kerberos, you
76       must turn on the kerberos_enabled boolean. Enabled by default.
77
78       setsebool -P kerberos_enabled 1
79
80
81
82       If you want to allow system to run with  NIS,  you  must  turn  on  the
83       nis_enabled boolean. Disabled by default.
84
85       setsebool -P nis_enabled 1
86
87
88
89       If  you  want to allow confined applications to use nscd shared memory,
90       you must turn on the nscd_use_shm boolean. Enabled by default.
91
92       setsebool -P nscd_use_shm 1
93
94
95
96       If you want to enable polyinstantiated directory support, you must turn
97       on the polyinstantiation_enabled boolean. Disabled by default.
98
99       setsebool -P polyinstantiation_enabled 1
100
101
102

PORT TYPES

104       SELinux defines port types to represent TCP and UDP ports.
105
106       You  can  see  the  types associated with a port by using the following
107       command:
108
109       semanage port -l
110
111
112       Policy governs the access  confined  processes  have  to  these  ports.
113       SELinux  rlogind  policy is very flexible allowing users to setup their
114       rlogind processes in as secure a method as possible.
115
116       The following port types are defined for rlogind:
117
118
119       rlogin_port_t
120
121
122
123       Default Defined Ports:
124                 tcp 543,2105
125
126
127       rlogind_port_t
128
129
130
131       Default Defined Ports:
132                 tcp 513
133

MANAGED FILES

135       The SELinux process type rlogind_t can manage files  labeled  with  the
136       following file types.  The paths listed are the default paths for these
137       file types.  Note the processes UID still need to have DAC permissions.

FILE CONTEXTS

275       SELinux requires files to have an extended attribute to define the file
276       type.
277
278       You can see the context of a file using the -Z option to ls
279
280       Policy  governs  the  access  confined  processes  have to these files.
281       SELinux rlogind policy is very flexible allowing users to  setup  their
282       rlogind processes in as secure a method as possible.
283
284       STANDARD FILE CONTEXT
285
286       SELinux  defines  the file context types for the rlogind, if you wanted
287       to store files with these types in a diffent paths, you need to execute
288       the  semanage  command  to  sepecify  alternate  labeling  and then use
289       restorecon to put the labels on disk.
290
291       semanage  fcontext   -a   -t   rlogind_var_run_t   '/srv/myrlogind_con‐
292       tent(/.*)?'
293       restorecon -R -v /srv/myrlogind_content
294
295       Note:  SELinux  often  uses  regular expressions to specify labels that
296       match multiple files.
297
298       The following file types are defined for rlogind:
299
300
301
302       rlogind_exec_t
303
304       - Set files with the rlogind_exec_t type, if you want to transition  an
305       executable to the rlogind_t domain.
306
307
308       Paths:
309            /usr/lib/telnetlogin,        /usr/sbin/in.rlogind,       /usr/ker‐
310            beros/sbin/klogind
311
312
313       rlogind_home_t
314
315       - Set files with the rlogind_home_t type, if you want to store  rlogind
316       files in the users home directory.
317
318
319       Paths:
320            /root/.rhosts,         /root/.rlogin,         /home/[^/]+/.rhosts,
321            /home/[^/]+/.rlogin
322
323
324       rlogind_keytab_t
325
326       - Set files with the rlogind_keytab_t type, if you want  to  treat  the
327       files as kerberos keytab files.
328
329
330
331       rlogind_tmp_t
332
333       -  Set  files with the rlogind_tmp_t type, if you want to store rlogind
334       temporary files in the /tmp directories.
335
336
337
338       rlogind_var_run_t
339
340       - Set files with the rlogind_var_run_t type, if you want to  store  the
341       rlogind files under the /run or /var/run directory.
342
343
344
345       Note:  File context can be temporarily modified with the chcon command.
346       If you want to permanently change the file context you need to use  the
347       semanage fcontext command.  This will modify the SELinux labeling data‐
348       base.  You will need to use restorecon to apply the labels.
349
350

COMMANDS

352       semanage fcontext can also be used to manipulate default  file  context
353       mappings.
354
355       semanage  permissive  can  also  be used to manipulate whether or not a
356       process type is permissive.
357
358       semanage module can also be used to enable/disable/install/remove  pol‐
359       icy modules.
360
361       semanage port can also be used to manipulate the port definitions
362
363       semanage boolean can also be used to manipulate the booleans
364
365
366       system-config-selinux is a GUI tool available to customize SELinux pol‐
367       icy settings.
