NAME

6       traceroute_selinux  - Security Enhanced Linux Policy for the traceroute
7       processes
8

DESCRIPTION

10       Security-Enhanced Linux secures the traceroute processes  via  flexible
11       mandatory access control.
12
13       The  traceroute  processes  execute with the traceroute_t SELinux type.
14       You can check if you have these processes running by executing  the  ps
15       command with the -Z qualifier.
16
17       For example:
18
19       ps -eZ | grep traceroute_t
20
21
22

ENTRYPOINTS

24       The  traceroute_t SELinux type can be entered via the traceroute_exec_t
25       file type.
26
27       The default entrypoint paths for the traceroute_t domain are  the  fol‐
28       lowing:
29
30       /bin/tracepath.*,        /bin/traceroute.*,       /usr/bin/tracepath.*,
31       /usr/bin/traceroute.*,      /usr/sbin/traceroute.*,       /usr/bin/lft,
32       /usr/bin/mtr, /usr/bin/nmap, /usr/sbin/mtr
33

PROCESS TYPES

35       SELinux defines process types (domains) for each process running on the
36       system
37
38       You can see the context of a process using the -Z option to ps
39
40       Policy governs the access confined processes have  to  files.   SELinux
41       traceroute  policy  is  very  flexible  allowing  users  to setup their
42       traceroute processes in as secure a method as possible.
43
44       The following process types are defined for traceroute:
45
46       traceroute_t
47
48       Note: semanage permissive -a traceroute_t  can  be  used  to  make  the
49       process  type  traceroute_t permissive. SELinux does not deny access to
50       permissive process types, but the AVC (SELinux  denials)  messages  are
51       still generated.
52
53

BOOLEANS

55       SELinux policy is customizable based on least access required.  tracer‐
56       oute policy is extremely flexible and has several booleans  that  allow
57       you  to  manipulate  the  policy  and  run traceroute with the tightest
58       access possible.
59
60
61
62       If you want to allow users to resolve user passwd entries directly from
63       ldap  rather  then  using  a  sssd server, you must turn on the authlo‐
64       gin_nsswitch_use_ldap boolean. Disabled by default.
65

PORT TYPES

160       SELinux defines port types to represent TCP and UDP ports.
161
162       You  can  see  the  types associated with a port by using the following
163       command:
164
165       semanage port -l
166
167
168       Policy governs the access  confined  processes  have  to  these  ports.
169       SELinux  traceroute  policy  is  very  flexible allowing users to setup
170       their traceroute processes in as secure a method as possible.
171
172       The following port types are defined for traceroute:
173
174
175       traceroute_port_t
176
177
178
179       Default Defined Ports:
180                 udp 64000-64010
181

FILE CONTEXTS

183       SELinux requires files to have an extended attribute to define the file
184       type.
185
186       You can see the context of a file using the -Z option to ls
187
188       Policy  governs  the  access  confined  processes  have to these files.
189       SELinux traceroute policy is very  flexible  allowing  users  to  setup
190       their traceroute processes in as secure a method as possible.
191
192       The following file types are defined for traceroute:
193
194
195
196       traceroute_exec_t
197
198       -  Set files with the traceroute_exec_t type, if you want to transition
199       an executable to the traceroute_t domain.
200
201
202       Paths:
203            /bin/tracepath.*,     /bin/traceroute.*,     /usr/bin/tracepath.*,
204            /usr/bin/traceroute.*,    /usr/sbin/traceroute.*,    /usr/bin/lft,
205            /usr/bin/mtr, /usr/bin/nmap, /usr/sbin/mtr
206
207
208       Note: File context can be temporarily modified with the chcon  command.
209       If  you want to permanently change the file context you need to use the
210       semanage fcontext command.  This will modify the SELinux labeling data‐
211       base.  You will need to use restorecon to apply the labels.
212
213

COMMANDS

215       semanage  fcontext  can also be used to manipulate default file context
216       mappings.
217
218       semanage permissive can also be used to manipulate  whether  or  not  a
219       process type is permissive.
220
221       semanage  module can also be used to enable/disable/install/remove pol‐
222       icy modules.
223
224       semanage port can also be used to manipulate the port definitions
225
226       semanage boolean can also be used to manipulate the booleans
227
228
229       system-config-selinux is a GUI tool available to customize SELinux pol‐
230       icy settings.
