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 all domains to execute in fips_mode, you must turn
61 on the fips_mode boolean. Enabled by default.
62 setsebool -P fips_mode 1
64 If you want to allow confined applications to run with kerberos, you
68 must turn on the kerberos_enabled boolean. Enabled by default.
69 setsebool -P kerberos_enabled 1
71 If you want to allow system to run with NIS, you must turn on the
75 nis_enabled boolean. Disabled by default.
76 setsebool -P nis_enabled 1
78 If you want to enable polyinstantiated directory support, you must turn
82 on the polyinstantiation_enabled boolean. Disabled by default.
83 setsebool -P polyinstantiation_enabled 1
85
89 SELinux defines port types to represent TCP and UDP ports.
90 You can see the types associated with a port by using the following
92 command:
93 semanage port -l
95 Policy governs the access confined processes have to these ports.
98 SELinux rlogind policy is very flexible allowing users to setup their
99 rlogind processes in as secure a method as possible.
100 The following port types are defined for rlogind:
102 rlogin_port_t
105 Default Defined Ports:
109 tcp 543,2105
110 rlogind_port_t
113 Default Defined Ports:
117 tcp 513
118
120 The SELinux process type rlogind_t can manage files labeled with the
121 following file types. The paths listed are the default paths for these
122 file types. Note the processes UID still need to have DAC permissions.

260 SELinux requires files to have an extended attribute to define the file
261 type.
262 You can see the context of a file using the -Z option to ls
264 Policy governs the access confined processes have to these files.
266 SELinux rlogind policy is very flexible allowing users to setup their
267 rlogind processes in as secure a method as possible.
268 STANDARD FILE CONTEXT
270 SELinux defines the file context types for the rlogind, if you wanted
272 to store files with these types in a diffent paths, you need to execute
273 the semanage command to specify alternate labeling and then use re‐
274 storecon to put the labels on disk.
275 semanage fcontext -a -t rlogind_var_run_t '/srv/myrlogind_con‐
277 tent(/.*)?'
278 restorecon -R -v /srv/myrlogind_content
279 Note: SELinux often uses regular expressions to specify labels that
281 match multiple files.
282 The following file types are defined for rlogind:
284 rlogind_exec_t
288 - Set files with the rlogind_exec_t type, if you want to transition an
290 executable to the rlogind_t domain.
291 Paths:
294 /usr/lib/telnetlogin, /usr/sbin/in.rlogind, /usr/ker‐
295 beros/sbin/klogind
296 rlogind_home_t
299 - Set files with the rlogind_home_t type, if you want to store rlogind
301 files in the users home directory.
302 Paths:
305 /root/.rhosts, /root/.rlogin, /home/[^/]+/.rhosts,
306 /home/[^/]+/.rlogin
307 rlogind_keytab_t
310 - Set files with the rlogind_keytab_t type, if you want to treat the
312 files as kerberos keytab files.
313 rlogind_tmp_t
317 - Set files with the rlogind_tmp_t type, if you want to store rlogind
319 temporary files in the /tmp directories.
320 rlogind_var_run_t
324 - Set files with the rlogind_var_run_t type, if you want to store the
326 rlogind files under the /run or /var/run directory.
327 Note: File context can be temporarily modified with the chcon command.
331 If you want to permanently change the file context you need to use the
332 semanage fcontext command. This will modify the SELinux labeling data‐
333 base. You will need to use restorecon to apply the labels.
334
337 semanage fcontext can also be used to manipulate default file context
338 mappings.
339 semanage permissive can also be used to manipulate whether or not a
341 process type is permissive.
342 semanage module can also be used to enable/disable/install/remove pol‐
344 icy modules.
345 semanage port can also be used to manipulate the port definitions
347 semanage boolean can also be used to manipulate the booleans
349 system-config-selinux is a GUI tool available to customize SELinux pol‐
352 icy settings.
