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(64)?/telnetlogin,        /usr/sbin/in.rlogind,       /usr/ker‐
31       beros/sbin/klogind
32

PROCESS TYPES

34       SELinux defines process types (domains) for each process running on the
35       system
36
37       You can see the context of a process using the -Z option to ps
38
39       Policy  governs  the  access confined processes have to files.  SELinux
40       rlogind policy is very flexible allowing users to setup  their  rlogind
41       processes in as secure a method as possible.
42
43       The following process types are defined for rlogind:
44
45       rlogind_t
46
47       Note:  semanage permissive -a rlogind_t can be used to make the process
48       type rlogind_t permissive. SELinux does not deny access  to  permissive
49       process  types, but the AVC (SELinux denials) messages are still gener‐
50       ated.
51
52

BOOLEANS

54       SELinux policy is customizable based on least access required.  rlogind
55       policy is extremely flexible and has several booleans that allow you to
56       manipulate the policy and run rlogind with the tightest  access  possi‐
57       ble.
58
59

PORT TYPES

154       SELinux defines port types to represent TCP and UDP ports.
155
156       You  can  see  the  types associated with a port by using the following
157       command:
158
159       semanage port -l
160
161
162       Policy governs the access  confined  processes  have  to  these  ports.
163       SELinux  rlogind  policy is very flexible allowing users to setup their
164       rlogind processes in as secure a method as possible.
165
166       The following port types are defined for rlogind:
167
168
169       rlogind_port_t
170
171
172
173       Default Defined Ports:
174                 tcp 513
175

MANAGED FILES

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

FILE CONTEXTS

282       SELinux requires files to have an extended attribute to define the file
283       type.
284
285       You can see the context of a file using the -Z option to ls
286
287       Policy  governs  the  access  confined  processes  have to these files.
288       SELinux rlogind policy is very flexible allowing users to  setup  their
289       rlogind processes in as secure a method as possible.
290
291       STANDARD FILE CONTEXT
292
293       SELinux  defines  the file context types for the rlogind, if you wanted
294       to store files with these types in a diffent paths, you need to execute
295       the  semanage  command  to  sepecify  alternate  labeling  and then use
296       restorecon to put the labels on disk.
297
298       semanage  fcontext   -a   -t   rlogind_var_run_t   '/srv/myrlogind_con‐
299       tent(/.*)?'
300       restorecon -R -v /srv/myrlogind_content
301
302       Note:  SELinux  often  uses  regular expressions to specify labels that
303       match multiple files.
304
305       The following file types are defined for rlogind:
306
307
308
309       rlogind_exec_t
310
311       - Set files with the rlogind_exec_t type, if you want to transition  an
312       executable to the rlogind_t domain.
313
314
315       Paths:
316            /usr/lib(64)?/telnetlogin,     /usr/sbin/in.rlogind,     /usr/ker‐
317            beros/sbin/klogind
318
319
320       rlogind_home_t
321
322       - Set files with the rlogind_home_t type, if you want to store  rlogind
323       files in the users home directory.
324
325
326       Paths:
327            /root/.rlogin,         /root/.rhosts,         /home/[^/]*/.rlogin,
328            /home/[^/]*/.rhosts, /home/staff/.rlogin, /home/staff/.rhosts
329
330
331       rlogind_keytab_t
332
333       - Set files with the rlogind_keytab_t type, if you want  to  treat  the
334       files as kerberos keytab files.
335
336
337
338       rlogind_tmp_t
339
340       -  Set  files with the rlogind_tmp_t type, if you want to store rlogind
341       temporary files in the /tmp directories.
342
343
344
345       rlogind_var_run_t
346
347       - Set files with the rlogind_var_run_t type, if you want to  store  the
348       rlogind files under the /run or /var/run directory.
349
350
351
352       Note:  File context can be temporarily modified with the chcon command.
353       If you want to permanently change the file context you need to use  the
354       semanage fcontext command.  This will modify the SELinux labeling data‐
355       base.  You will need to use restorecon to apply the labels.
356
357

COMMANDS

359       semanage fcontext can also be used to manipulate default  file  context
360       mappings.
361
362       semanage  permissive  can  also  be used to manipulate whether or not a
363       process type is permissive.
364
365       semanage module can also be used to enable/disable/install/remove  pol‐
366       icy modules.
367
368       semanage port can also be used to manipulate the port definitions
369
370       semanage boolean can also be used to manipulate the booleans
371
372
373       system-config-selinux is a GUI tool available to customize SELinux pol‐
374       icy settings.
