NAME

6       dccd_selinux - Security Enhanced Linux Policy for the dccd processes
7

DESCRIPTION

9       Security-Enhanced  Linux secures the dccd processes via flexible manda‐
10       tory access control.
11
12       The dccd processes execute with the dccd_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 dccd_t
19
20
21

ENTRYPOINTS

23       The dccd_t SELinux type can be entered via the dccd_exec_t file type.
24
25       The default entrypoint paths for the dccd_t domain are the following:
26
27       /usr/sbin/dccd, /usr/libexec/dcc/dccd
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       dccd policy is very flexible allowing users to setup  their  dccd  pro‐
37       cesses in as secure a method as possible.
38
39       The following process types are defined for dccd:
40
41       dcc_client_t, dcc_dbclean_t, dccd_t
42
43       Note:  semanage  permissive  -a  dccd_t can be used to make the process
44       type dccd_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.   dccd
51       policy is extremely flexible and has several booleans that allow you to
52       manipulate the policy and run dccd with the tightest access possible.
53
54
55
56       If you want to allow all domains to execute in fips_mode, you must turn
57       on the fips_mode boolean. Enabled by default.
58
59       setsebool -P fips_mode 1
60
61
62
63       If  you  want  to  allow  system  to run with NIS, you must turn on the
64       nis_enabled boolean. Disabled by default.
65
66       setsebool -P nis_enabled 1
67
68
69

PORT TYPES

71       SELinux defines port types to represent TCP and UDP ports.
72
73       You can see the types associated with a port  by  using  the  following
74       command:
75
76       semanage port -l
77
78
79       Policy  governs  the  access  confined  processes  have to these ports.
80       SELinux dccd policy is very flexible allowing users to setup their dccd
81       processes in as secure a method as possible.
82
83       The following port types are defined for dccd:
84
85
86       dcc_port_t
87
88
89
90       Default Defined Ports:
91                 udp 6276,6277
92

MANAGED FILES

94       The  SELinux process type dccd_t can manage files labeled with the fol‐
95       lowing file types.  The paths listed are the default  paths  for  these
96       file types.  Note the processes UID still need to have DAC permissions.

FILE CONTEXTS

169       SELinux requires files to have an extended attribute to define the file
170       type.
171
172       You can see the context of a file using the -Z option to ls
173
174       Policy governs the access  confined  processes  have  to  these  files.
175       SELinux dccd policy is very flexible allowing users to setup their dccd
176       processes in as secure a method as possible.
177
178       STANDARD FILE CONTEXT
179
180       SELinux defines the file context types for the dccd, if you  wanted  to
181       store  files  with  these types in a diffent paths, you need to execute
182       the semanage command to sepecify alternate labeling and  then  use  re‐
183       storecon to put the labels on disk.
184
185       semanage fcontext -a -t dccd_var_run_t '/srv/mydccd_content(/.*)?'
186       restorecon -R -v /srv/mydccd_content
187
188       Note:  SELinux  often  uses  regular expressions to specify labels that
189       match multiple files.
190
191       The following file types are defined for dccd:
192
193
194
195       dccd_exec_t
196
197       - Set files with the dccd_exec_t type, if you want to transition an ex‐
198       ecutable to the dccd_t domain.
199
200
201       Paths:
202            /usr/sbin/dccd, /usr/libexec/dcc/dccd
203
204
205       dccd_tmp_t
206
207       -  Set files with the dccd_tmp_t type, if you want to store dccd tempo‐
208       rary files in the /tmp directories.
209
210
211
212       dccd_var_run_t
213
214       - Set files with the dccd_var_run_t type, if you want to store the dccd
215       files under the /run or /var/run directory.
216
217
218
219       Note:  File context can be temporarily modified with the chcon command.
220       If you want to permanently change the file context you need to use  the
221       semanage fcontext command.  This will modify the SELinux labeling data‐
222       base.  You will need to use restorecon to apply the labels.
223
224

COMMANDS

226       semanage fcontext can also be used to manipulate default  file  context
227       mappings.
228
229       semanage  permissive  can  also  be used to manipulate whether or not a
230       process type is permissive.
231
232       semanage module can also be used to enable/disable/install/remove  pol‐
233       icy modules.
234
235       semanage port can also be used to manipulate the port definitions
236
237       semanage boolean can also be used to manipulate the booleans
238
239
240       system-config-selinux is a GUI tool available to customize SELinux pol‐
241       icy settings.
