NAME

6       pptp_selinux - Security Enhanced Linux Policy for the pptp processes
7

DESCRIPTION

9       Security-Enhanced  Linux secures the pptp processes via flexible manda‐
10       tory access control.
11
12       The pptp processes execute with the pptp_t SELinux type. You can  check
13       if  you  have  these processes running by executing the ps command with
14       the -Z qualifier.
15
16       For example:
17
18       ps -eZ | grep pptp_t
19
20
21

ENTRYPOINTS

23       The pptp_t SELinux type can be entered via the pptp_exec_t file type.
24
25       The default entrypoint paths for the pptp_t domain are the following:
26
27       /usr/sbin/pptp
28

PROCESS TYPES

30       SELinux defines process types (domains) for each process running on the
31       system
32
33       You can see the context of a process using the -Z option to ps
34
35       Policy  governs  the  access confined processes have to files.  SELinux
36       pptp policy is very flexible allowing users to setup  their  pptp  pro‐
37       cesses in as secure a method as possible.
38
39       The following process types are defined for pptp:
40
41       pptp_t
42
43       Note:  semanage  permissive  -a  pptp_t can be used to make the process
44       type pptp_t permissive. SELinux does  not  deny  access  to  permissive
45       process  types, but the AVC (SELinux denials) messages are still gener‐
46       ated.
47
48

BOOLEANS

50       SELinux policy is customizable based on least  access  required.   pptp
51       policy is extremely flexible and has several booleans that allow you to
52       manipulate the policy and run pptp with the tightest access possible.

MANAGED FILES

150       The  SELinux process type pptp_t can manage files labeled with the fol‐
151       lowing file types.  The paths listed are the default  paths  for  these
152       file types.  Note the processes UID still need to have DAC permissions.

FILE CONTEXTS

220       SELinux requires files to have an extended attribute to define the file
221       type.
222
223       You can see the context of a file using the -Z option to ls
224
225       Policy governs the access  confined  processes  have  to  these  files.
226       SELinux pptp policy is very flexible allowing users to setup their pptp
227       processes in as secure a method as possible.
228
229       STANDARD FILE CONTEXT
230
231       SELinux defines the file context types for the pptp, if you  wanted  to
232       store  files  with  these types in a diffent paths, you need to execute
233       the semanage command  to  sepecify  alternate  labeling  and  then  use
234       restorecon to put the labels on disk.
235
236       semanage fcontext -a -t pptp_var_run_t '/srv/mypptp_content(/.*)?'
237       restorecon -R -v /srv/mypptp_content
238
239       Note:  SELinux  often  uses  regular expressions to specify labels that
240       match multiple files.
241
242       The following file types are defined for pptp:
243
244
245
246       pptp_exec_t
247
248       - Set files with the pptp_exec_t type, if you  want  to  transition  an
249       executable to the pptp_t domain.
250
251
252
253       pptp_log_t
254
255       -  Set files with the pptp_log_t type, if you want to treat the data as
256       pptp log data, usually stored under the /var/log directory.
257
258
259
260       pptp_var_run_t
261
262       - Set files with the pptp_var_run_t type, if you want to store the pptp
263       files under the /run or /var/run directory.
264
265
266
267       Note:  File context can be temporarily modified with the chcon command.
268       If you want to permanently change the file context you need to use  the
269       semanage fcontext command.  This will modify the SELinux labeling data‐
270       base.  You will need to use restorecon to apply the labels.
271
272

COMMANDS

274       semanage fcontext can also be used to manipulate default  file  context
275       mappings.
276
277       semanage  permissive  can  also  be used to manipulate whether or not a
278       process type is permissive.
279
280       semanage module can also be used to enable/disable/install/remove  pol‐
281       icy modules.
282
283       semanage boolean can also be used to manipulate the booleans
284
285
286       system-config-selinux is a GUI tool available to customize SELinux pol‐
287       icy settings.
