6 rlogind_selinux - Security Enhanced Linux Policy for the rlogind pro‐
7 cesses
8
10 Security-Enhanced Linux secures the rlogind processes via flexible
11 mandatory access control.
12 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 For example:
18 ps -eZ | grep rlogind_t
20
24 The rlogind_t SELinux type can be entered via the rlogind_exec_t file
25 type.
26 The default entrypoint paths for the rlogind_t domain are the follow‐
28 ing:
29 /usr/lib/telnetlogin, /usr/sbin/in.rlogind, /usr/kerberos/sbin/klogind
31
33 SELinux defines process types (domains) for each process running on the
34 system
35 You can see the context of a process using the -Z option to ps
37 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 The following process types are defined for rlogind:
43 rlogind_t
45 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
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 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 setsebool -P authlogin_nsswitch_use_ldap 1
65 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 setsebool -P fips_mode 1
72 If you want to allow confined applications to run with kerberos, you
76 must turn on the kerberos_enabled boolean. Enabled by default.
77 setsebool -P kerberos_enabled 1
79 If you want to allow system to run with NIS, you must turn on the
83 nis_enabled boolean. Disabled by default.
84 setsebool -P nis_enabled 1
86 If you want to allow confined applications to use nscd shared memory,
90 you must turn on the nscd_use_shm boolean. Disabled by default.
91 setsebool -P nscd_use_shm 1
93 If you want to enable polyinstantiated directory support, you must turn
97 on the polyinstantiation_enabled boolean. Disabled by default.
98 setsebool -P polyinstantiation_enabled 1
100
104 SELinux defines port types to represent TCP and UDP ports.
105 You can see the types associated with a port by using the following
107 command:
108 semanage port -l
110 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 The following port types are defined for rlogind:
117 rlogin_port_t
120 Default Defined Ports:
124 tcp 543,2105
125 rlogind_port_t
128 Default Defined Ports:
132 tcp 513
133
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.

277 SELinux requires files to have an extended attribute to define the file
278 type.
279 You can see the context of a file using the -Z option to ls
281 Policy governs the access confined processes have to these files.
283 SELinux rlogind policy is very flexible allowing users to setup their
284 rlogind processes in as secure a method as possible.
285 STANDARD FILE CONTEXT
287 SELinux defines the file context types for the rlogind, if you wanted
289 to store files with these types in a diffent paths, you need to execute
290 the semanage command to sepecify alternate labeling and then use
291 restorecon to put the labels on disk.
292 semanage fcontext -a -t rlogind_var_run_t '/srv/myrlogind_con‐
294 tent(/.*)?'
295 restorecon -R -v /srv/myrlogind_content
296 Note: SELinux often uses regular expressions to specify labels that
298 match multiple files.
299 The following file types are defined for rlogind:
301 rlogind_exec_t
305 - Set files with the rlogind_exec_t type, if you want to transition an
307 executable to the rlogind_t domain.
308 Paths:
311 /usr/lib/telnetlogin, /usr/sbin/in.rlogind, /usr/ker‐
312 beros/sbin/klogind
313 rlogind_home_t
316 - Set files with the rlogind_home_t type, if you want to store rlogind
318 files in the users home directory.
319 Paths:
322 /root/.rhosts, /root/.rlogin, /home/[^/]+/.rhosts,
323 /home/[^/]+/.rlogin
324 rlogind_keytab_t
327 - Set files with the rlogind_keytab_t type, if you want to treat the
329 files as kerberos keytab files.
330 rlogind_tmp_t
334 - Set files with the rlogind_tmp_t type, if you want to store rlogind
336 temporary files in the /tmp directories.
337 rlogind_var_run_t
341 - Set files with the rlogind_var_run_t type, if you want to store the
343 rlogind files under the /run or /var/run directory.
344 Note: File context can be temporarily modified with the chcon command.
348 If you want to permanently change the file context you need to use the
349 semanage fcontext command. This will modify the SELinux labeling data‐
350 base. You will need to use restorecon to apply the labels.
351
354 semanage fcontext can also be used to manipulate default file context
355 mappings.
356 semanage permissive can also be used to manipulate whether or not a
358 process type is permissive.
359 semanage module can also be used to enable/disable/install/remove pol‐
361 icy modules.
362 semanage port can also be used to manipulate the port definitions
364 semanage boolean can also be used to manipulate the booleans
366 system-config-selinux is a GUI tool available to customize SELinux pol‐
369 icy settings.
