6 fingerd_selinux - Security Enhanced Linux Policy for the fingerd pro‐
7 cesses
8
10 Security-Enhanced Linux secures the fingerd processes via flexible
11 mandatory access control.
12 The fingerd processes execute with the fingerd_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 fingerd_t
20
24 The fingerd_t SELinux type can be entered via the fingerd_exec_t file
25 type.
26 The default entrypoint paths for the fingerd_t domain are the follow‐
28 ing:
29 /usr/sbin/[cef]fingerd, /usr/sbin/in.(x)?fingerd,
31 /etc/cron.weekly/(c)?fingerd
32
34 SELinux defines process types (domains) for each process running on the
35 system
36 You can see the context of a process using the -Z option to ps
38 Policy governs the access confined processes have to files. SELinux
40 fingerd policy is very flexible allowing users to setup their fingerd
41 processes in as secure a method as possible.
42 The following process types are defined for fingerd:
44 fingerd_t
46 Note: semanage permissive -a fingerd_t can be used to make the process
48 type fingerd_t permissive. SELinux does not deny access to permissive
49 process types, but the AVC (SELinux denials) messages are still gener‐
50 ated.
51
54 SELinux policy is customizable based on least access required. fingerd
55 policy is extremely flexible and has several booleans that allow you to
56 manipulate the policy and run fingerd with the tightest access possi‐
57 ble.
58 If you want to allow users to resolve user passwd entries directly from
62 ldap rather then using a sssd server, you must turn on the authlo‐
63 gin_nsswitch_use_ldap boolean. Disabled by default.

172 SELinux defines port types to represent TCP and UDP ports.
173 You can see the types associated with a port by using the following
175 command:
176 semanage port -l
178 Policy governs the access confined processes have to these ports.
181 SELinux fingerd policy is very flexible allowing users to setup their
182 fingerd processes in as secure a method as possible.
183 The following port types are defined for fingerd:
185 fingerd_port_t
188 Default Defined Ports:
192 tcp 79
193
195 The SELinux process type fingerd_t can manage files labeled with the
196 following file types. The paths listed are the default paths for these
197 file types. Note the processes UID still need to have DAC permissions.
198 cluster_conf_t
200 /etc/cluster(/.*)?
202 cluster_var_lib_t
204 /var/lib/pcsd(/.*)?

240 SELinux requires files to have an extended attribute to define the file
241 type.
242 You can see the context of a file using the -Z option to ls
244 Policy governs the access confined processes have to these files.
246 SELinux fingerd policy is very flexible allowing users to setup their
247 fingerd processes in as secure a method as possible.
248 STANDARD FILE CONTEXT
250 SELinux defines the file context types for the fingerd, if you wanted
252 to store files with these types in a diffent paths, you need to execute
253 the semanage command to sepecify alternate labeling and then use
254 restorecon to put the labels on disk.
255 semanage fcontext -a -t fingerd_var_run_t '/srv/myfingerd_con‐
257 tent(/.*)?'
258 restorecon -R -v /srv/myfingerd_content
259 Note: SELinux often uses regular expressions to specify labels that
261 match multiple files.
262 The following file types are defined for fingerd:
264 fingerd_etc_t
268 - Set files with the fingerd_etc_t type, if you want to store fingerd
270 files in the /etc directories.
271 fingerd_exec_t
275 - Set files with the fingerd_exec_t type, if you want to transition an
277 executable to the fingerd_t domain.
278 Paths:
281 /usr/sbin/[cef]fingerd, /usr/sbin/in.(x)?fingerd,
282 /etc/cron.weekly/(c)?fingerd
283 fingerd_log_t
286 - Set files with the fingerd_log_t type, if you want to treat the data
288 as fingerd log data, usually stored under the /var/log directory.
289 fingerd_var_run_t
293 - Set files with the fingerd_var_run_t type, if you want to store the
295 fingerd files under the /run or /var/run directory.
296 Note: File context can be temporarily modified with the chcon command.
300 If you want to permanently change the file context you need to use the
301 semanage fcontext command. This will modify the SELinux labeling data‐
302 base. You will need to use restorecon to apply the labels.
303
306 semanage fcontext can also be used to manipulate default file context
307 mappings.
308 semanage permissive can also be used to manipulate whether or not a
310 process type is permissive.
311 semanage module can also be used to enable/disable/install/remove pol‐
313 icy modules.
314 semanage port can also be used to manipulate the port definitions
316 semanage boolean can also be used to manipulate the booleans
318 system-config-selinux is a GUI tool available to customize SELinux pol‐
321 icy settings.
