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. Disabled 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.

233 SELinux requires files to have an extended attribute to define the file
234 type.
235 You can see the context of a file using the -Z option to ls
237 Policy governs the access confined processes have to these files.
239 SELinux rlogind policy is very flexible allowing users to setup their
240 rlogind processes in as secure a method as possible.
241 STANDARD FILE CONTEXT
243 SELinux defines the file context types for the rlogind, if you wanted
245 to store files with these types in a diffent paths, you need to execute
246 the semanage command to sepecify alternate labeling and then use
247 restorecon to put the labels on disk.
248 semanage fcontext -a -t rlogind_var_run_t '/srv/myrlogind_con‐
250 tent(/.*)?'
251 restorecon -R -v /srv/myrlogind_content
252 Note: SELinux often uses regular expressions to specify labels that
254 match multiple files.
255 The following file types are defined for rlogind:
257 rlogind_exec_t
261 - Set files with the rlogind_exec_t type, if you want to transition an
263 executable to the rlogind_t domain.
264 Paths:
267 /usr/lib/telnetlogin, /usr/sbin/in.rlogind, /usr/ker‐
268 beros/sbin/klogind
269 rlogind_home_t
272 - Set files with the rlogind_home_t type, if you want to store rlogind
274 files in the users home directory.
275 Paths:
278 /root/.rhosts, /root/.rlogin, /home/[^/]+/.rhosts,
279 /home/[^/]+/.rlogin
280 rlogind_keytab_t
283 - Set files with the rlogind_keytab_t type, if you want to treat the
285 files as kerberos keytab files.
286 rlogind_tmp_t
290 - Set files with the rlogind_tmp_t type, if you want to store rlogind
292 temporary files in the /tmp directories.
293 rlogind_var_run_t
297 - Set files with the rlogind_var_run_t type, if you want to store the
299 rlogind files under the /run or /var/run directory.
300 Note: File context can be temporarily modified with the chcon command.
304 If you want to permanently change the file context you need to use the
305 semanage fcontext command. This will modify the SELinux labeling data‐
306 base. You will need to use restorecon to apply the labels.
307
310 semanage fcontext can also be used to manipulate default file context
311 mappings.
312 semanage permissive can also be used to manipulate whether or not a
314 process type is permissive.
315 semanage module can also be used to enable/disable/install/remove pol‐
317 icy modules.
318 semanage port can also be used to manipulate the port definitions
320 semanage boolean can also be used to manipulate the booleans
322 system-config-selinux is a GUI tool available to customize SELinux pol‐
325 icy settings.
