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 all domains to execute in fips_mode, you must turn
63       on the fips_mode boolean. Enabled by default.
64
65       setsebool -P fips_mode 1
66
67
68
69       If  you  want  to  allow  system  to run with NIS, you must turn on the
70       nis_enabled boolean. Disabled by default.
71
72       setsebool -P nis_enabled 1
73
74
75
76       If you want to allow confined users the ability to execute the ping and
77       traceroute  commands,  you  must  turn on the selinuxuser_ping boolean.
78       Disabled by default.
79
80       setsebool -P selinuxuser_ping 1
81
82
83

PORT TYPES

85       SELinux defines port types to represent TCP and UDP ports.
86
87       You can see the types associated with a port  by  using  the  following
88       command:
89
90       semanage port -l
91
92
93       Policy  governs  the  access  confined  processes  have to these ports.
94       SELinux traceroute policy is very  flexible  allowing  users  to  setup
95       their traceroute processes in as secure a method as possible.
96
97       The following port types are defined for traceroute:
98
99
100       traceroute_port_t
101
102
103
104       Default Defined Ports:
105                 udp 64000-64010
106

FILE CONTEXTS

108       SELinux requires files to have an extended attribute to define the file
109       type.
110
111       You can see the context of a file using the -Z option to ls
112
113       Policy governs the access  confined  processes  have  to  these  files.
114       SELinux  traceroute  policy  is  very  flexible allowing users to setup
115       their traceroute processes in as secure a method as possible.
116
117       The following file types are defined for traceroute:
118
119
120
121       traceroute_exec_t
122
123       - Set files with the traceroute_exec_t type, if you want to  transition
124       an executable to the traceroute_t domain.
125
126
127       Paths:
128            /bin/tracepath.*,     /bin/traceroute.*,     /usr/bin/tracepath.*,
129            /usr/bin/traceroute.*,    /usr/sbin/traceroute.*,    /usr/bin/lft,
130            /usr/bin/mtr, /usr/bin/nmap, /usr/sbin/mtr
131
132
133       Note:  File context can be temporarily modified with the chcon command.
134       If you want to permanently change the file context you need to use  the
135       semanage fcontext command.  This will modify the SELinux labeling data‐
136       base.  You will need to use restorecon to apply the labels.
137
138

COMMANDS

140       semanage fcontext can also be used to manipulate default  file  context
141       mappings.
142
143       semanage  permissive  can  also  be used to manipulate whether or not a
144       process type is permissive.
145
146       semanage module can also be used to enable/disable/install/remove  pol‐
147       icy modules.
148
149       semanage port can also be used to manipulate the port definitions
150
151       semanage boolean can also be used to manipulate the booleans
152
153
154       system-config-selinux is a GUI tool available to customize SELinux pol‐
155       icy settings.
